Since the epidemic, the demand for disposable flocking swabs has continued to rise. In China, all major cities have successively introduced normal nucleic acid testing, so disposable flocking swabs are the most demanding consumables. Flocking swab usually refers to one of the medical devices used for nucleic acid sampling. Because the amount of nucleic acid samples collected and released by flocking swab is better than that of cotton swab, it is mainly used for collecting samples. Flocking swab is generally harmless to human body, because its material is mainly nylon short fiber, and nylon is a synthetic man-made fiber, which is extremely stable and will not produce substances harmful to human body. Therefore, when collecting nucleic acid, use the flocking swab. Don't worry too much about the damage to human health usually caused by the flocking swab. Just cooperate with medical personnel to sample. Common types of disposable sterile sampling swabs (flocking head+sponge head): throat swab, oropharynx swab, nasopharynx swab, throat swab, oral swab, nasal swab, front nose swab, middle nose swab, nose swab, short nose swab, children swab, adult swab, cervical swab, gynecologic swab, female swab, vaginal swab, HPV swab, TCT swab, influenza swab, monkeypox swab, virus sampling swab, stool stool swab DNA swab, gene detection swab, nucleic acid swab, antigen swab, judicial swab and other swabs Common uses of disposable sterile sampling swab (flocking head+sponge head): nucleic acid detection sampling, antigen detection self testing sampling, gene detection sampling, and collection applicable to microorganisms. It can assist hospitals or laboratories to detect viruses or study virus sampling for human or animal natural cavities, such as throat, nose, mouth, vagina, etc. Disposable sterile sampling swab (flocking head+sponge head) GMP workshop has excellent production quality, high collection and release, no irritation and allergic reaction during sampling Single use sterile sampling swab (flocking head+sponge head) for more convenient collection and breaking Better sample release rate, higher sample adsorption and sensitivity.

How do you clean and maintain glasses, cameras and jewelry Is this correct As a nearsighted person, glasses are an inseparable part of my daily life. Because wearing glasses can help my blurred eyes see clearly. However, when I use the glasses, the lenses will be constantly touched and scratched. Inevitably, the lens will be scratched or stuck with hand prints, dust, eyelashes and other dirty things. Therefore, we have to clean the glasses. Most people are Wipe the lens directly with the eyeglass cloth Others use clothes to clean their glasses In fact, this is not desirable Glasses cloth is not used to clean glasses There are many dust particles on the lens at ordinary times If you directly dry wipe with glasses cloth The glasses cloth will let these dust particles Rub back and forth on the lens It is similar to rubbing back and forth on the lens with sandpaper The damage to the lens can be imagined after a long time Cleaning tools are essential when cleaning lenses. Since many young friends have not formed good cleaning habits at the beginning, they will directly use towels or clothes to clean the lenses for convenience, and even use paper towels to clean them! This means that the possibility of lens scratching is basically 100%! The little friends may not know that such behavior not only reduces the clarity of the lenses, but also may start to decrease the vision during the long-term use of blurred glasses, and eventually the myopia becomes higher and higher, so that they regret it. Of course, some people will also say that I can use professional glasses cloth when cleaning glasses? There is no problem with this answer. Because professional glasses cloth can really bring good cleaning effect to glasses. The question is whether the glasses cloth purchased by the glasses manufacturer or the glasses shop is specially used to wipe the glasses, which is rather important. A long time ago, Xiaobian began to look for glasses cloth to wipe the lenses. Through some glasses shops, he bought glasses cloth from them to wipe the lenses. At the beginning, these glasses cloth really brought a good cleaning experience. But when the glasses cloth gets dirty, the wiping effect becomes worse and worse! When I want to use it after cleaning, I start to lose hair and chips again! Finally, Xiaobian decided to give up the eyewear cloth and use the above-mentioned clothes, towels or some soft paper towels to clean. It is conceivable that the result has not brought any improvement to the lens cleaning. Microfiber dust-free cloth: uniform, fine, soft, elastic and extensible No hair can be wiped off and no residue Used for wiping and protecting different types of products Glasses cloth is mainly used to wrap glasses Wrap the glasses with glasses cloth Put it in the glasses case like this The friction between the lens of the glasses and the case can be avoided Microfiber dust-free cloth is woven from polyester / nylon composite microfiber. It is a wiping cloth that has been opened and shaped for a long time. It not only has the characteristics of soft and delicate cloth surface, but also will not damage the surface of fragile products. The microfiber dust-free cloth has a very strong decontamination ability for handprints, inks and powders. It is widely used in optical glass wiping and fragile product surface wiping. Xiaobian has used microfiber dust-free cloth to wipe the lenses for one year, and the lens clarity of the glasses is still the same as that at the time of purchase, bright and transparent, with very good effect! Moreover, it can be cleaned and reused many times. It is simply a good cleaning cloth for wiping glasses, TV, computer and other digital furniture! Do you think that the glasses cloth is only used for wiping glasses for so many years It's important not only to take care of your eyes Glasses also need to be taken care of

I suggest you understand these two points as soon as possible Have you ever noticed that some people often pull out their ears, or even unconsciously want to pull out their ears... Put a long and thin ear scoop or cotton swab into their ears, and each touch will lead to a burst of numbness. If you can dig out a large piece of earwax from the inside after a while of groping, you must have had the sense of achievement from the inside out, and many people can't stop~ Why is it refreshing to pull out your ears? There are abundant nerves distributed in our ear canal. Pulling out the ear can stimulate the nerves at the end of the ear canal, thus promoting the secretion of dopamine in the brain, thus producing this fascinating sensation. Moreover, when pulling out the ear, we will produce a spontaneous perceptual meridian reaction, also known as intracranial climax and ear sound. It is a kind of unique stimulation generated in your brain, scalp and other parts through tactile or auditory sensory stimulation, which makes people feel happy and even unable to stop. Therefore, many people not only pick out their own ears, but also go to the shops specializing in ear picking and pay for help. But sometimes there may be hidden dangers! Picking out the ear may induce cross infection? That's why! Case: three months ago, Aunt Liu's ears grew grain by grain of rice like granulation, which was itchy and bleeding when she pulled it out with her hands. So he hurried to the hospital for examination. After the doctor examined Aunt Liu, he also examined Aunt Liu's wife and found the same granulation. Later, the doctor told them that they had papilloma of the external auditory canal, caused by papillomavirus (HPV). How can HPV virus breed in good ears? After some inquiry, the doctor found out that the problem was actually the wife. The wife usually went to the barber's shop to take out her ears. The ear scoop was not sufficiently disinfected, and different customers used the same tool, causing cross infection. The manifestation of papilloma of external auditory canal In the early stage of the tumor, there will be itching, blocking or hearing loss of the ear canal; Then ear digging may be accompanied by bleeding or digging out meat pieces; Accompanied by infection, purulence and ear pain may occur. In addition, the external auditory canal can also be seen with single or multiple lesions of different sizes, rough and uneven surface, pedicled or non pedicled brownish yellow tumors, which are hard to touch; Those with infection may be congested and swollen in the form of granulation; Those with local blood circulation disorder can be black and part of them can fall off naturally. If you have the above symptoms, you must see a doctor in time. Although papilloma of the external auditory canal is a benign tumor, it has the risk of malignant transformation into cancer of the external auditory canal! In addition, there is a hidden risk that people often pull out their ears unconsciously. Often pull out your ears. These risks should be known as soon as possible Cause abnormal secretion of ear wax and reduce the ability to protect the ear Digging the ear often may cause abnormal secretion of ear wax, resulting in more and more ear wax, and the newly secreted cerumen will change from the original flake into debris, thus reducing the ability to protect the ear. Ear wax pushes deeper and deeper, causing earwax embolism The Chinese otolaryngology society points out that if you use a cotton swab to pull out the ear, the wax in the ear may be pushed deeper and deeper. If it accumulates over a long period of time, it may form an earwax embolism. Once the ear plugs are formed, there will be ear pain, ear swelling, dizziness, hearing loss and other problems, which may also cause inflammation. Damage the tympanic membrane, causing otitis media or deafness The tympanic membrane is a very thin membrane, with a thickness of only 0.1mm. If the tool penetrates into the ear canal, it will damage the tympanic membrane and cause perforation. At this time, it is easy to cause otitis media in case of water or cold in the ear. Tip: acute suppurative otitis media can cause hearing loss, dizziness, facial paralysis, meningitis, sigmoid sinus thrombophlebitis, brain abscess, etc. many of these complications are fatal. If the acute otitis media does not heal for a long time, it will become chronic otitis media, which will easily lead to the gradual destruction of the middle ear structure by inflammation, resulting in permanent hearing loss and tinnitus, and even total deafness. Therefore, in case of persistent ear pain, tinnitus, ear tightness and hearing loss, it is necessary to seek medical examination in time. Ear wax is not useless. You don't have to take it out often In fact, ear wax is not excrement. It is also called cerumen in medicine. It is mainly composed of exfoliated skin cells, sweat and secretion of cerumen glands. Don't think ear wax is superfluous. It can actually help protect your ears: Proper ear wax has 4 advantages ① Ear wax can not only block the dust particles from the outside, but also prevent insects and other microorganisms from entering the ear. It has the function of protecting the skin of the external auditory canal and adhering to external objects. ② Earwax can also cushion the impact of sound waves on the eardrum and protect those who have been wearing earphones. ③ Ear wax containing oil can keep the ear canal moist and keep the tympanic membrane deep in the ear canal dry. ④ Ear wax contains lysozyme, immunoglobulin, fatty acid, etc., which can form a layer of acid film on the surface of the ear canal skin, leaving the external ear canal in an acidic environment, thus having the function of mild sterilization and inhibiting the growth of fungi. Ear wax can be discharged without pulling out Most people's ear wax can be discharged by themselves. For example, when we talk, eat and yawn, the ear wax will be pushed by the sweat in the ear canal with the movement of the jaw, and will be quietly discharged from the ear canal. Therefore, you don't need to pick out your ears often. Precautions for correct ear removal: ① wash your hands before ear removal to avoid bringing bacteria into your ears. ② Soak the medical disinfection cotton swab in warm boiled water, squeeze it slightly, put it into the external auditory canal, and gently rotate it in one direction to take out the earwax. It is better not to use tools such as ear scoop to avoid damaging the ear canal or tympanic membrane. ③ Don't dig your ears frequently, usually once a week or so; However, in places with more dust or people with oil ears, it can be shorter and controlled according to their own conditions. In addition, when pulling out the ear, it is necessary to ensure that the utensils are disinfected and hygienic. When pulling out the ear stick and other tools at home, it is also necessary to assign special personnel to clean them in place to avoid infection.

Now many people use iodophor cotton swabs at home, because the germicidal spectrum of iodophor is broader than that of other medium effect disinfectants, and it can effectively kill bacterial propagators, fungi, Mycobacterium tuberculosis, viruses and other microorganisms. Although it has been documented that some varieties of iodophor, such as povidone iodine, polyethylene glycol iodine, polyol ether iodine, have a certain killing effect on bacterial spores, it takes a long time. Therefore, iodophor disinfectant, which has the characteristics of low pain and good sterilization effect, is milder than alcohol in treating wounds and is conducive to wound healing. It is often praised as the best choice for treating wounds, and iodophor cotton swabs are more convenient for wound treatment, but many people have some misunderstandings in the operation methods. Today, I will explain the use methods of iodophor cotton swabs. First of all, we should tell you that we must buy regular iodophor disinfectant, have production license, font size and other key signs, and do not buy three no products. When using, first open a cotton swab of iodophor disinfectant, see the end of the cotton swab with a colored ring end, and gently push it up along the package. After successfully taking out the iodophor disinfectant cotton stick, gently break the end of the cotton swab with the color strip upward and the other swab head downward, and then the iodophor disinfectant in the cotton stick will quickly flow from the end of the color strip to the swab head at the other end. In 1-2 seconds, the swab head without the color strip will be quickly soaked with Iodophor disinfectant, and the iodophor disinfectant will fill the whole swab head. At this time, gently wipe the abraded wound or the incision caused by carelessness and apply it back and forth until the iodophor of iodophor disinfectant cotton swab head is used. In fact, in addition to treating wounds, iodophor cotton swabs also play a certain role in neonatal care. After the umbilical cord of the baby is cut, a wound will be formed, which is an important way for bacteria to invade the body of the newborn. Light cases can cause omphalitis, serious cases can lead to sepsis, and the consequences of improper care are very serious. To learn umbilical cord care, we must first follow three principles, and take care of the baby on this basis: keep dry, avoid friction Avoid sultry. Iodophor disinfectant is selected because it has a strong killing effect on bacteria, fungi, spores, molds and some viruses. Compared with ethanol and iodine, iodophor has low irritation to the skin, so it is reliable and safe to disinfect the umbilical wound of newborns.

Recently, there are rumors that the sampling swab used in nucleic acid and antigen detection is toxic and looks even more shocking: it (sampling swab) is not called a cotton swab, because it is a chemical fiber, and its professional name is fluorescent probe. It contains easily broken nylon fiber, carcinogenic highly toxic ethylene oxide, mogilons fiber, radioactive element technetium, carcinogenic fluorescent agents... It will damage the blood-brain barrier, facial nerve and olfactory nerve. This rumor is not new. Since the outbreak of this round of epidemic, the sampling swabs have been poisonous, and they will appear every once in a while, which can be clarified all the time. In late April, the Shanghai Municipal Drug Administration Department also said at the Shanghai epidemic prevention and control press conference that it would implement high-frequency supervision on covid-19 reagents, medical masks, protective clothing, disposable samplers (swabs), etc. However, or because some members of the public do not understand the composition and function of the sampling swab, as well as the principle of nucleic acid and antigen detection, they misunderstand the sampling swab, leading to false rumors. There is no mogilons fiber According to the verification, the latest rumor that the sampling swab is not a cotton swab but a chemical fiber is not wrong, but other statements are wrong. At present, the top of most nucleic acid and antigen sampling swabs are not absorbent cotton of daily cotton swabs, but nylon fiber flocking swabs. However, this does not mean that the fibers of the sampling swab are easy to break. The fine nylon fiber is fixed on the top of the sampler to better collect samples. The rumor that mogilons fiber is nonsense. There is no mojilong fiber in the raw material market, only the controversial medical symptom named mojilong disease. The combination of Morgellons' disease and sampling swabs is completely nonsense, and the rumor mongers deliberately mislead the public with obscure words. The swab does not contain technetium oxide The sampling swab is produced for sampling and does not contain any soaking reagent or reagent; At the same time, sampling swabs belong to medical devices, and the basic requirement of qualified products is non-toxic and harmless. Therefore, the rumored ethylene oxide technetium is also irrelevant to the sampling swab. According to national regulations, sampling swabs, also known as disposable samplers, belong to medical device products, which not only need to be recorded for production, but also have strict production environmental requirements and quality supervision standards. Qualified products are definitely non-toxic and harmless. At the same time, the sampling swab is a general product in the medical field, which can sample different parts and also be used in different detection behaviors. It is not specially produced for nucleic acid detection or antigen detection, so the swab will not contain other reagents. Fluorescence detection is the operation after sampling, which has nothing to do with citizens The online news also includes the statement that the professional name of the sampling swab is that the fluorescent probe contains carcinogenic fluorescent agents. According to experts, fluorescent probes are indeed involved in nucleic acid detection, but they are completely different from sampling swabs. The sampling swab is a sampler used to collect human samples on the inner surface of the nasopharynx in the sampling links of antigen detection and nucleic acid detection. Fluorescent probes are used in sample detection, which refer to DNA probes labeled with fluorescent molecules. This component belongs to PCR reaction reagent, which needs to be kept away from light at -20 ℃. It is only added and used in laboratory test tubes. In short, in the swab sampling process, fluorescent probes will not be used at all, which is unlikely to affect the health of citizens. Mixing the fluorescent probe with the sampling swab shows that the rumor monger has sinister intentions. The sampling swab does not need to be sterile There are also rumors that most of the sampling swabs currently used are not labeled sterile, so they are unsafe. This is another misunderstanding about the sterility and non sterility of medical devices. In the field of medical devices, the concepts of sterility and non sterility are different from the common understanding. Sterility refers to the state without viable microorganisms. After sterilization, the theoretical probability of the existence of viable microorganisms in sterile medical devices should not exceed the negative power of 10. Therefore, sterile medical devices are required only in the use environment with particularly high requirements. While non sterile and non sterile medical devices cannot be as strict as sterile medical devices, which are almost free of bacteria, they will not hide dirt. All medical devices must meet certain health requirements before they can be qualified for marketing. Qualified products on the market can be safely used and sampled. In order to dispel the public's concern about non sterile sampling swabs, experts also cited an example: daily paper towels and other non sterile products often directly contact the mouth, nose, eyes and other parts, but the public did not get sick. Therefore, there is no need to worry about non sterile sampling swabs. However, if the unused sampling swabs are found to be damaged or contaminated, they should be discarded, and the supplier can be contacted to protect their rights. Why do you feel uncomfortable in your throat or nose after sampling? Some netizens also suggested that they felt uncomfortable in their pharynx and nose after each sampling, so they suspected that the sampling swab was toxic. This is also a misunderstanding of sampling swabs. Industry insiders pointed out that there are individual differences. Some people's throat or nasal cavity are sensitive to sampling, so they will feel uncomfortable after sampling. In addition, there are also differences in the operation methods of detection personnel. As the saying goes, gestures are light and heavy, which may also cause some discomfort. However, these discomfort will be relieved soon after stopping sampling, and will not cause harm to the body, which has nothing to do with the sampling swab. Some time ago, local epidemics occurred in many parts of the country, so it is necessary to carry out multiple rounds of nucleic acid testing for all staff again. I believe nucleic acid has become one of our daily work. Sometimes when we see nucleic acid spots, we always want to queue up to do it once, just for two words of peace of mind.

With the start of the anti epidemic war, in the process of large-scale nucleic acid screening, new rumors about covid-19 nucleic acid testing also took the opportunity to rub the heat. For example, do not eat oranges or drink coke before the covid-19 test, which will change the pH in the mouth and lead to a positive test result. Another example is that the cotton swabs used to make nucleic acid poke throat contain fluorescent agents, which can cause cancer and so on. What is the truth? The latest scientific gossip list refutes the rumors about the new crown. Rumor: the sampling swab tested by Xinguan is poisonous truth There are rumors that the cotton swabs used for nucleic acid detection and antigen detection are stained with toxic carcinogens such as fluorescent agents, which will lead to pharyngitis and even cancer. In fact, the swab used for detection and sampling does not contain any reagent, nor does it need to contain reagent. At the same time, sampling swabs belong to medical devices, and the basic requirement is non-toxic and harmless. The claim that the sampling swab is poisonous is completely nonsense. Cotton swabs in daily life are made of absorbent cotton. The sampling swab looks similar to ordinary cotton swabs, but the top is actually a flocking swab. The flocking swab is made of nylon fiber flocking technology, and the front end is coated with nylon short fibers fixed vertically, so that there are no absorption holes in the collection area of the whole collection swab. In this way, the collected samples will not be dispersed and retained in the fiber, which is conducive to faster and more efficient sample elution. Relevant data show that flocking swabs can elute more than 85% of the sample collection volume. In contrast, cotton swabs made of absorbent cotton cannot completely collect and elute samples because of their strong absorption capacity. Rumor: eating oranges and drinking Coke will lead to positive antigen test truth The covid-19 antigen detection kit has been put on the market, making rapid detection more convenient. However, will the self-test results of specific groups be affected by factors such as diet? Antigen detection should be carried out in strict accordance with the instructions. If the operation does not meet the standards, the results obtained are meaningless, but it cannot be considered that the antigen detection results are inaccurate. The principle of the detection kit is simply to capture virus antigens through specific antibodies, but the combination of antigen and antibody needs to occur at an appropriate pH (PH). Under normal circumstances, the sample treatment solution soaked with swabs contains a buffer system, which can ensure the binding of antigen and antibody at the appropriate pH. However, if cola, orange juice and other liquids are directly dropped on the antigen detection kit, the inappropriate pH value will cause non-specific false positive results. So, can you do antigen detection after eating acidic food? The answer is yes. The swab needs to be soaked in the sample treatment solution after sampling before testing. The sample treatment solution contains Tris glycine, high concentration sodium chloride and other substances, which can effectively stabilize the structure of the gold labeled antibody and avoid interfering with the reaction. As long as the collected swab is mixed with the sample treatment solution according to the standard operation process, there is no need to worry about false positives caused by acids. Rumor: sleeping in the east-west direction will lead to insomnia truth Some people think that when sleeping, the body should conform to the direction of the earth's magnetic field, that is, lying north-south. Sleeping with things will lead to insomnia. In fact, the earth's magnetic field has little effect on the human body. In this regard, experts from the sleep disorders coordination group of the Chinese Medical Association said that human beings are in various magnetic fields all the time, and the human body also has magnetic fields, but the human body's magnetic field is one tenth of the earth's magnetic field strength, and the two have established a certain balance. Therefore, the influence of the earth's magnetic field on the human body is negligible. At present, there is no research that can confirm that the direction of lying down will affect the quality of sleep. Insomnia is mainly caused by sleep rhythm disorders, such as often changing work and rest times, sleeping late and getting up late, and doing things unrelated to sleep in bed (reading books, playing mobile phones), which may affect human rhythm and aggravate insomnia. In addition, insomnia is also affected by age, genetic factors, health environment and so on. Mental diseases and taking drugs will also cause sleep disorders to varying degrees. It is precisely because there are many reasons for insomnia, so the treatment of insomnia cannot be given to thousands of people. Targeted treatment programs should be given, including improving the sleep environment, establishing good living habits, improving emotional state, appropriate drugs and physical therapy. Rumor: frequent hand shaking is Parkinson's disease truth The term of hand shaking is called tremor, which is a typical symptom of Parkinson's disease in the public's eyes, but the presence of hand shaking symptoms does not mean that there must be Parkinson's disease. Psychological stress, muscle fatigue or taking some drugs can also lead to tremor. On the other hand, not all patients with Parkinson's disease will shake their hands - some patients only have limb stiffness without tremor, which is called non tremor Parkinson's disease. In fact, bradykinesia is the core symptom of Parkinson's disease. The patient may feel that the fine actions such as brushing teeth and beating eggs are inflexible, the arm cannot swing freely when walking, the writing becomes smaller, and the expression becomes dull. Patients may also have trunk roll, limb involuntary movement or obvious postural abnormalities in some periods, which is called dyskinesia or dystonia in medicine. With the progress of the course of disease, patients with advanced Parkinson's disease will have symptoms such as unstable walking and easy to fall, and eventually cannot walk independently and need to rely on a wheelchair or lie in bed. In addition, Parkinson's disease also has many non motor symptoms, including olfactory failure, depression, sleep problems, decreased intelligence, frequent urination, intractable constipation, etc. it usually requires the participation of multiple disciplines to provide a better comprehensive treatment plan, not just to see whether the hand trembles or not. Rumor: negative pressure ward will cause patients to have difficulty breathing truth The negative pressure ward mainly treats patients with infectious diseases transmitted through aerosol and droplet respiratory tract. Because the air pressure in this kind of ward is lower than that outside the ward, only fresh air outside is allowed to flow into the ward, and the air polluted by pathogens in the ward will not leak out, but will be discharged to a fixed place in time through a special channel. Although the air pressure of the negative pressure ward is smaller than that of the outside world, it is generally only 15 PA less, while the atmospheric pressure on the ground is generally about 100 kPa, and the change of 15 Pa will not affect the patient's breathing at all. Moreover, the professional negative pressure ward is equipped with fresh air equipment. The fresh air entering the ward needs to be purified, and the discharged air also needs to be fully treated to ensure safety before it can be discharged into the external environment. Rumor: taking smart drugs can improve candidates' concentration truth Seeing that the college entrance examination season is coming, some parents hope to buy smart drugs to improve their children's concentration in order to make their children get good grades. The so-called medicine that can improve concentration was once popular among candidates and parents, online writers, postgraduate entrance examination and public examination in the name of smart medicine. In fact, smart drugs are actually central nervous system stimulants such as modafinil, Ritalin and Minda, which belong to a class of controlled psychotropic drugs. Such drugs are used clinically to treat children's attention deficit and hyperactivity disorder, severe narcolepsy, etc. healthy people will feel energetic at the beginning of taking them, but they will soon show side effects such as nausea, insomnia, headache, and may also form drug dependence. Rumor: food made of glutinous rice is difficult to digest truth People think glutinous rice is difficult to digest, probably because Tangyuan, yuanxiao, babaofan and other foods also contain a lot of sugar and fat, giving people a greasy feeling. In fact, sticky glutinous rice is easier to digest than other pasta. Staple foods that people often eat, such as rice and white flour, mainly contain amylose, while more than 99% of glutinous rice is amylopectin. Its molecular structure is more forked, so it is easier to gelatinize. When the human digestive system decomposes starch, it hydrolyzes it from the end of the molecule, so amylopectin with many branches is actually more efficient to be hydrolyzed and digested. However, because of faster digestion, compared with the rice flour we usually eat, the glycemic index (GI) of glutinous rice is also faster (GI of rice is 82, while GI of glutinous rice is 87), so we should not eat too much at one time.

The COVID-19 has made nucleic acid testing a daily necessity for people. What has happened to nucleic acid testing from a cotton swab to a paper report? According to reports, medical workers first take samples from the examiner's oropharynx or nasopharynx, put the sampled cotton swabs into a closed test tube, and then send the sampled samples to the laboratory for testing. After signing for the samples, the laboratory staff should disassemble the samples one by one and enter the information into the system. It is worth noting that because nucleic acid detection is an extremely sensitive and precise experiment with certain risks, all nucleic acid detection laboratories have special environmental requirements, so they cannot be detected casually on the spot. Before detection, the nucleic acid in the sample needs to be extracted and then amplified. "The extraction area of nucleic acid and the amplification area of nucleic acid are polluted areas, so these areas are negative pressure." Sunxuemin, head of Jinan aidikang clinical laboratory, said that the nucleic acid extraction area has the largest degree of pollution, and the negative pressure of the whole area is also the largest, so as to ensure the Non-Proliferation of pollutants in the nucleic acid extraction area. So, what is amplification? Because the virus is invisible to the naked eye, and a small number of samples are not easy to detect, "amplification" is to increase the number of viruses. Next, you need to configure reagents in a completely zero polluted environment, and then "add samples". It is worth noting that only "amplification" requires 45 cycles, "Because DNA and RNA are double stranded, we need to open this chain and then replicate. When one chain is opened and then replicated, it becomes two chains, and when two chains are opened and then replicated, it becomes eight chains, and so on. If there is a detection signal, it is getting stronger and stronger. If not, 45 cycles of amplification is also 0. 45 cycles of amplification is equivalent to the 45th power of 2." With such a large quantity base, we can detect whether it is positive or negative. However, the detection process is not over. Next, we have to add various negative controls, positive controls, quality control, normal saline controls, etc. to monitor the quality of the whole process of this experiment and ensure the reliability and accuracy of the test results.

Many friends like to use cameras to record important moments. When purchasing a mobile phone, the pixels and photographic effect of the mobile phone will be regarded as the main selection criteria. Some friends who have high requirements for photos will still choose to take photos with cameras. What if the camera is dirty? There are various cleaning appliances on the market, not all of which are useful. Commonly used cleaners include lens paper, lens pen, cleaning brush, hair dryer, dust-free cotton swab, etc. they can also be equipped with anti-static gloves. As for lens water, there is no need to simply clean it. The lens water on the market will be corrosive to a certain extent, and excessive use will damage the coating. 1. How to use lens paper Many people buy lens paper and wipe it directly on the lens like a paper towel, which is actually a wrong use. When using the lens paper, roll it into a barrel, and then pull the two ends of the lens paper to divide it into two sections. You will find a lot of fine hairs on the damaged part. Start from the middle of the lens with these fine hairs and gently wipe them clockwise. General lens cloth is mainly used to wipe the camera body and lens body, and some large areas of dirt or water droplets. Because the lens cloth will drop some fine fibers, wiping the lens with it will not only scratch the lens, but also pollute the lens. 2. usage of Lens Pen One end of the lens pen on the market is a brush, and the other end is a soft pen tip with adsorption function, which is mainly used to clean the fingerprint and oil stains of the lens. Like lens paper, wipe the lens clockwise from the center to the outside. Do not wipe it at will. 3. How to use a clean cotton swab The dust-free cleaning rod is mainly used to clean some places that are not convenient to be cleaned with a brush, such as the hot shoe interface, eyepiece groove and other places that are easy to hide dust. I never thought I could clean the lens with a lint free cotton swab, right? Dustless cotton swabs are generally used for precision instruments, but they can also be used for camera body lenses. Dustless cotton swabs are widely used. It is much easier to use other lens cleaning products.

The medical protective mask is applicable to the protection of medical personnel and relevant staff from airborne respiratory infectious diseases. It is a kind of dense self-priming filtering medical protective articles with high protection grade. It is especially suitable for patients with respiratory infectious diseases transmitted through air or close droplets. It can filter particles in the air and block droplets, blood, body fluids, secretion droplets, etc. it is a disposable product. It is applicable to medical personnel who fight against the front line of the epidemic and have high (high) exposure risk. Medical protective masks are generally not recommended to be worn continuously for more than 6 hours, up to 8 hours. If the medical protective mask is contaminated, deformed, damaged or has difficulty breathing during use, it must be replaced immediately. It refers to the medical protective mask that can prevent the transmission of infectious particles in the blood and respiratory secretions, and can prevent the transmission of infectious particles in the respiratory tract. Composition and function of medical protective mask: medical protective mask is composed of mask surface and tensioning belt. The mask surface is divided into three layers: inner layer, middle layer and outer layer. The inner layer is ordinary sanitary gauze or non-woven fabric, and the middle layer is single-layer or multi-layer. A layer of ultra-fine polypropylene melt blown material layer, and the outer layer is non-woven fabric or ultra-thin polypropylene melt blown material layer. The high-efficiency medical protective mask has strong hydrophobicity and air permeability, and has a significant filtering effect on small virus aerosol or harmful dust. The overall filtering effect is good. The medical protective mask has a good fit to the wearer's face. It can filter particles in the air and block pollutants such as droplets, blood, body fluids and secretions. The filtration efficiency of non oily particles can reach more than 95%. Commonly used personal protective equipment for the transmission of diseases. Medical protective masks are made of one or more fabrics with isolation function, such as virus aerosol and virus containing liquid. It has low air flow resistance, synthetic blood barrier, specific strength, filtration efficiency, surface moisture resistance and flame retardancy. Scope of application of medical protective mask: This product is a good protective article. It is recommended to wear it in case of serious environmental pollution or sudden medical infectious diseases (such as respiratory infectious diseases) to prevent patients or environmental viruses from infecting users. Correct use of medical masks: 1. Wash hands with soap and water or alcoholic hand sanitizer before and after wearing masks. 2. The colored surface faces outward and the metal sheet faces upward. 3. Fasten the mask belt, press the nose clip with two fingertips, and move along the bridge of the nose to both sides to make it close to the face. 4. The mask should completely cover the mouth, nose and chin. 5. The disposable mask worn for a long time shall be replaced every 4 hours. 6. Patients with heart and respiratory diseases should not wear masks for a long time. 7. Put the discarded mask into a plastic bag or paper bag, and then throw it into a covered dustbin. Classification of medical masks: Medical masks are classified by belt type: usually including belt type, head wearing type, ear hanging type, etc. Belt type. Headwear is suitable for medical staff who wear it for a long time. It is troublesome to wear, but it has no burden on the ears; Ear wearing: easy to wear, suitable for frequent wearing and falling off. Medical masks are divided into plane type, folding type, duckbill type, fish type and arch type. The plane mask is easy to carry, but the sealing performance is poor; Foldable duckbill shape. The fish shaped mask is easy to carry; Arched breathing space is large, with good sealing, but it is inconvenient to carry. According to the executive standard, medical masks are generally divided into disposable medical masks, medical surgical masks and medical protective masks. According to the microbial status of the product, medical masks can be divided into non sterile masks and sterile masks. The non sterile mask shall meet the microbial control standard, that is, a certain number of microorganisms are allowed, but it must be within the controllable range and free of relevant pathogens. The sterile mask is sterilized accordingly and is in a sterile state within the period of validity. In our daily life, what are the tips for purchasing medical masks? 1. Dust suppression. The dust suppression performance of medical mask depends on its ability to block fine dust, especially respiratory dust below 2.5 microns. Because the size of dust particles can directly enter the alveoli, it has a greater impact on human health. This product is composed of filter material, activated carbon fiber felt or non-woven fabric. Dust below 2.5 microns can be transported to the filter material through the filter material. 2. Sealing performance. The solution to prevent facial side leakage is to prevent unfiltered air from inhaling the medical mask from the gap between the mask and the face. Air, like water, has less resistance and flows first. If the shape of the mask is not close to the face, harmful substances in the air will leak into the human respiratory tract from nearby. Well, even if you choose a better mask with filter material. Your health. According to many foreign laws and regulations, workers should regularly conduct mask sealing tests. The purpose is to ensure that workers choose the correct mask and wear it according to the correct procedures.

Cotton swabs are not only widely used, but also have good bending resistance. The bar shall be able to withstand an external force of 100g without permanent deformation or fracture. So, what is the correct use of cotton swabs? 1 cotton swabs can be used after opening the bag. 2. Take out the cotton swab from the end of the stick. If removed from the end of the cotton, bacteria on the hand can contaminate the sterile cotton. 3 medical cotton swabs can directly treat wounds. However, it should be noted that the cotton swab should be stored in a well ventilated room with a relative humidity of no more than 80% and no corrosive gas to avoid high temperature. Medical cotton swabs are generally in direct contact with patients' wounds, and have high requirements for disinfection. In addition, the selection of absorbent cotton raw materials for making cotton swabs must meet the requirements of national standards and industrial standards. There are also requirements for the quality of bars. Whether plastic rods, paper rods or wood rods, they should meet the specified requirements and can withstand certain external forces without permanent deformation or fracture. 4 household cotton swabs generally do not deal with human wounds, and are only suitable for general skin cleaning. When using a household cotton swab to clean the baby's body, pay attention to the operation when the baby is quiet to prevent the cotton swab from poking the baby. Precautions for using cotton swabs Pay attention to the shelf life Hospital cotton swabs are mostly packed with double-layer paper. This kind of cotton swab is sterilized by high temperature and high pressure. The shelf life is generally two weeks when it is unopened. However, in humid areas in the South or in the rainy season in spring, bacteria will penetrate into the packaging because the paper is easy to be damp. Therefore, the shelf life of cotton swabs is likely to be only about one week. It's important to keep cotton swabs When storing cotton swabs, ensure that the package is sealed, and pay attention to that the cotton swabs are stored in a well ventilated room with a relative humidity of no more than 80% and no corrosive gas, so as to avoid high temperature. Household cotton swabs should not be used for wound disinfection Ordinary families usually do not use many cotton swabs, and there is no condition to disinfect the remaining cotton swabs within 24 hours after opening. Therefore, it is recommended to use those cotton swabs as ordinary cotton swabs or discard them. Never use them for wound treatment, especially for infants. Sterile cotton swabs are needed for skin disinfection. Once contaminated, the wound may be infected. Some people think that the cotton swab should be stained with alcohol, iodophor and other disinfectants anyway. There is no bacteria at all. They don't know that disinfection and sterilization are two different concepts. Disinfection is to kill pathogenic microorganisms on articles; Sterilization is to completely kill all pathogenic microorganisms and non pathogenic microorganisms, including spores. Sterilization includes disinfection, but disinfection cannot replace sterilization. In other words, although disinfectants such as alcohol and iodophor can kill pathogenic microorganisms, if the cotton swab is not sterile, but contains microorganisms such as spores, the disinfectant has nothing to do with it, and even the disinfectant will be polluted. Therefore, ensuring the sterility of cotton swabs is an important measure to prevent infection.

With the improvement of health concept, many friends will prepare some basic medical supplies at home for emergencies. In the general concept of friends, cotton swabs are used for disinfection. Of course, some friends use them to pull out their ears, make-up and so on. However, what many friends don't know is that if the cotton swab is used incorrectly, it will have the opposite effect. I will use my experience to teach you how to use cotton swabs correctly. 1 usage of cotton swab First of all, let me tell you the most basic use of cotton swabs: disinfection. Let's take skin disinfection as an example. We focus on the parts to be disinfected, rotate in one direction in front of us, and the diameter should be more than 5cm. A cotton swab can only be used once and cannot be recycled to avoid cross infection. There is also a common function in front of us: pressing the wound. There are two pressing methods: one is ordinary pressing, which stops bleeding. Take subcutaneous injection (vaccination) and intramuscular injection (hip injection) as examples. The cotton swab can be pressed parallel to the wound. Second, press longitudinally. Taking intravenous injection (mainly blood test) as an example, the injection method of general nurses is: enter the skin from the top or side of the vein, and then sneak into the vein along the vein. So generally, this kind of wound looks like one wound from the surface of the skin after the needle is pulled out, but you are actually two wounds. If the pressing method is incorrect, the skin color around the needle inlet will appear blue and purple. In fact, this is caused by congestion in your skin wound. If this happens, don't worry. The congestion will disperse by itself in about a week. At this time, your face should be pressed vertically along the vein, as shown in the figure: Cotton swab pressing time. The pressing time of the cotton swab after pulling out the needle is also exquisite. Generally, people who are about 40 years old, have good coagulation function and have not taken anticoagulants for about five minutes. For people over 40 years old or who have taken anticoagulants, the pressing time should be about 10 minutes or more, depending on their personal situation. Cotton swab pressing taboo. After pulling out the needle, the most taboo of cotton swab pressing is to press for two minutes to see if it will bleed. Generally speaking, if you press for less than five minutes, the wound will bleed. When you pick up a cotton swab from time to time, it will only cause congestion, blue and purple around your skin. Finally, I hope that friends must standardize the use of cotton swabs in life and avoid unnecessary trouble. Hope to help you. Medical Cotton Swab 2 precautions for using cotton swabs 1. Pay attention to the shelf life. Hospital cotton swabs are mostly packed with double-layer paper. This kind of cotton swab is sterilized by high temperature and high pressure. In the unopened state, the shelf life is generally two weeks. In humid areas in the south, or rainy seasons in spring, the shelf life of cotton swabs is only about one week, because the paper is easy to be damp, which makes bacteria penetrate into the packaging. 2. Do not disinfect the wound with household cotton swabs. The cotton swabs usually used by ordinary families are not many, and there is no condition to disinfect the cotton swabs for the remaining 24 hours after opening. Therefore, it is recommended that those cotton swabs be used as ordinary cosmetic cotton swabs or discarded. They should not be used for wound treatment, especially for infants. Sterile cotton swabs are essential for skin disinfection. Once contaminated, the wound may be infected. Some people think that cotton swabs should be dipped in disinfectants such as alcohol and iodophor anyway, and some bacteria will not get in the way. They don't know that disinfection and sterilization are two different concepts. Disinfection is to kill pathogenic microorganisms on articles; Sterilization is the complete killing of all pathogenic and non pathogenic microorganisms on the article, including spores. Sterilization includes sterilization and cannot replace sterilization. In other words, although disinfectants such as alcohol and iodophor can kill pathogenic microorganisms, if the cotton swab is not sterile, but contains microorganisms such as spores, the disinfectant is powerless, and even the disinfectant will be contaminated. Therefore, sterile swabs are important measures to prevent infection. 3. It is important to keep cotton swabs. When storing cotton swabs, the package shall be sealed. It shall also be noted that the cotton swabs shall be stored in a room with relative humidity less than 80%, no corrosive gas and good ventilation to avoid high temperature. It is dangerous to use three cotton swabs multiple times. The germicidal efficacy of liquid medicine contaminated with cotton swabs may also be greatly reduced. Dr. Jiao told you that every time you need to use disinfectant, you might as well pour enough disinfectant into another small container first, so that the whole bottle of disinfectant will not be polluted by one use. In fact, it is not only the wrong method of use, but also the different use of these disinfectants by many people. According to Dr. Jiao, the bactericidal effect of Red Mercury lasts longer and is generally used when the skin is abraded. However, red mercury has potential mercury poisoning risk due to its mercury content, so it is generally not used in major hospitals at present. It should be noted that red mercury should never be used with iodine containing preparations, otherwise the combination of the two will cause oxidation reaction and burn the skin. Compared with alcohol, iodine has stronger bactericidal power, but due to its strong irritation, it will not cause skin trauma, such as boils. The use of iodine is also taboo. Infants and adults cannot use it on the face and scrotum. Alcohol is as irritating as iodine, but due to its short duration, it can also be used when there is a wound on the skin, but the bactericidal effect is poor. Compared with the above three disinfectants, Dr. Jiao recommends that you use iodine and fluorine. Fluoride has the same bactericidal ability as iodine, but its permeability is less than iodine. Therefore, it is less harmful to the skin and safer to use. Iodine and fluoride can be used whether there are wounds on the skin or only small boils. It is reported that iodine and fluorine can be bought in pharmacies. In addition, disinfectants should not be stored for too long. Experts suggest that family drugs should be packaged in small doses of 100 ~ 200 ml. After the potion is bought home, it must be sealed and stored in a cool place. 4. The harm of often using cotton swab to pull out the ear Earwax not only prevents dust and dirt from entering the eardrum, but also provides additional antibacterial and lubricating effects. In addition, there are many magical places in the human body - in fact, your ears can clean automatically. After earwax is dry, every time you move your chin (whether it's lunch or talking nonsense to friends), it will help your ears remove old earwax (almost like taking an elevator). The problem is that we always think we are much smarter than our physical functions, so we like to poke in our ears. Sure, cotton swabs look small, but their function is actually to push the wax deep into the ear to places where it cannot be cleaned automatically. Earwax is trapped deep, while fungi, bacteria and viruses accumulate in the outer ear, which can make us feel pain and infection. Pushing the wax deeper can also clog the ear holes and cause hearing problems. If you push the wax deeper and cause the eardrum to rupture, the pain is unspeakable. When you really need to clean your ears, or when you go to see a doctor to clean them, that is, when you feel your ears are full of this pile of dirt, or when you feel too much earwax and hearing loss. Aao-hnsf thought it was time to remind people, so it issued an official statement and even set up a website about taking out ears with cotton swabs to discuss whether a well-known brand that recommended people to take out ears with cotton swabs was reliable. In daily life, it is recommended that you do not often pull out your ears with a cotton swab, whether adults or children. This will have a certain impact on your hearing. It can be cleaned properly, but not too much. Teach you how to remove nail polish with a cotton swab. Step 1: take a cotton swab, hold the cotton swab with a pencil and apply nail wash. Remember to soak the cotton swab completely in nail washing water; Step 2: remove the nail polish on the small nail, and wipe it back and forth from the root of the nail to the front edge of the nail with a cotton swab stained with nail oil and water; Step 3: remove the nail polish left in the nail groove from the protective film of the nail skin to the nail along the nail groove; Step 4: change a cotton swab and slowly remove the nail polish that has not been removed once. Tips: 1: Just hold the cotton swab by holding the pen, which can better control the cotton swab; 2: Change a new cotton swab every time you wipe your nails; 3. removing nail polish with this method will be more time-consuming and labor-saving than other methods, but removing nail polish with a cotton swab can reduce the number of hand contact with chemicals, that is, reduce the injury to the opponent; 4: When wiping, be sure to soak the cotton swab in nail washing water. Because the cotton swab is thick, it is easier to clean nail polish only when it is soaked in nail washing water. The method of removing nail polish with a cotton swab is very simple and easy to operate. This method is also healthy and suitable for use at home.

In addition to wearing anti-static clothes and anti-static shoes, the personnel working in the dust-free production workshop also need to use some other dust-free products to better ensure the safety of the products, so that the products can pass the quality inspection and obtain greater market space. In the dust-free workshop, cleaning consumables are essential. With the help of sponge head purification cotton swab, I believe it will be better. Imported polyurethane sponge is adopted for the sponge head purification cotton swab, so that the purification cotton swab has good cleaning effect. In the process of wiping the camera, it is very convenient to use a dust-free cotton swab, especially some small gaps. For places that are difficult to wipe, this sponge head cotton swab can be used to obtain a good solution. The sponge head has strong adsorption capacity and can timely and effectively clean up the fine dust in the precision instrument. Especially for some instruments that need to dip cotton swabs into alcohol and other liquids, the head of the dust-free cotton swab is tight and not easy to loosen, which is conducive to wiping products and adjustment, and then help more workshops for the production and processing of instruments. While improving, it also brings great convenience to employees in the business process. The purifying cotton swab is a disposable product and can be discarded after wiping. After wiping with a dust-free cotton swab, the cleanliness of the product can be better improved. This can ensure that the processed products have higher quality and more competitive advantages in the market. The purifying sponge swab has been well applied and popularized in the laser electronic instrument and microscope in the chemical laboratory. With the help of purifying sponge suction head, we can get the data analysis and research, as well as the products in the sales process. There is much room for progress and development.

Today, let's talk about the performance of purification swabs. Does the selection of purification swabs determine the quality of products? Why is there such a saying? Because the purification cotton swab is generally used to wipe electronic products and prevent dust, anti-static will be used, but the current electronic products will be damaged by a little static electricity in the production process. At this time, you need to use an anti-static purification cotton swab, Therefore, it is best to choose the appropriate purification cotton swab, which needs to understand the performance characteristics of the purification cotton swab. Purification cotton swab, also known as dust-free cotton swab, has a soft surface and is easy to wipe the sensitive surface, leaving no dust after friction. It has good water absorption and cleaning efficiency. The cleaning and packaging of products are completed in the super clean workshop. Under the condition of good static control, a large mobile phone manufacturer failed in product testing one after another, and found problems in step-by-step inspection. Clean the production line with a cotton swab. Ordinary purification cotton swabs will produce high electrostatic voltage during wiping, which will lead to electrostatic discharge or dust absorption of some parts, causing intangible damage to product quality. The purifying cotton swab is indeed practical in the clean room environment, but the electrostatic charging voltage of the purifying cotton swab has been ignored. People are always easy to make mistakes in familiar things, mainly because they are familiar and easy to ignore some details. In the production line of electronic factory, there are many products with high requirements for static electricity. Most production lines are also equipped with good anti-static products, so that the electrostatic voltage can be controlled below 1000V, but sometimes some details are often ignored. The manufacturer did ignore this detail at the beginning, but the purification cotton swab still needs to be used. Therefore, in the selection of purification cotton swab, the purification cotton swab with anti-static function should be selected. Therefore, when selecting the purification cotton swab, the purification cotton swab with anti-static function should be selected. Purification cotton swab is generally used to wipe LCD, wafer, PCB, digital camera lens, camera film, CD and other high-tech products, and will not produce dust particles. At the same time, it can also absorb liquid and dust particles to achieve cleaning effect. Anti static cleaning cotton swab can solve these characteristics of anti-static and dust-free for you.

Dust-proof and anti static cotton swabs, also known as dustproof and anti-static wiping sticks, and antistatic cleaning cotton swabs, are divided into three main categories: cloth dustproof antistatic cotton swabs, sponge head dust removes, free antistatic cotton swabs and foam head dust-proof antistatic cotton swabs. Therefore, the dust-free and anti-static cotton swab is more suitable for cleaning very small and accurate areas. The main application fields of cotton swabs are concentrated in clean rooms, integrated circuits, precision instruments, liquid crystal displays, microelectronics, biomedicine, automobiles, hard disks, optics, food industry, aerospace and other fields. There are essential differences between dust-free wiper and cotton swab. The swab head is made of cotton. It cannot be cleaned without dust, and there is a risk of scraping off in the wiping process. Compared with the dust-free cloth wiping rod, the head material is divided into sponge head and cloth head, which have been cleaned in the dust-free room and cleaned and packaged in the dust-free room. The scrubbing consumables used must be above grade 100, so only the wiping cloth and wiping rod can meet the requirements, and the wiping paper and cotton swab can only be wiped with products in ordinary environment. Dust free cotton and dust-free paper are the only choice for precision cleaning and wiping. Under the special environment of the production process (the rag cannot be wiped), it can remove pollutants and keep clean. Low chemical residue after scrubbing. Flammable and explosive, easy to operate, environmentally friendly and harmless. Most cleaning swabs are conductive grade to keep operators and tools grounded. It is suitable for level 10 purification workshop with different packaging. Medical cotton is used to clean and disinfect skin or wounds. Daily cotton swab Immediate coating includes a cotton swab and a cotton swab fixed at one end of the cotton swab. The cotton swab is a hollow rod in which the liquid medicine is stored. One end of the hollow rod fixed on the cotton head is provided with an oil seal for sealing the liquid medicine. Compared with the prior art, the utility model is a hollow rod storage structure, which makes the cotton swab have the characteristics of ready to use, convenient and fast. It is suitable for necessary sanitary supplies such as hospitals, families, schools and hotels. It is also very suitable for travel. Dustless cotton swab is a kind of dustless wiping consumables used in industry. It can also be called purification cotton swab or anti-static cotton swab, sponge stick, etc. Eliminate pollutants in the special environment of the production process to keep clean. It is mainly used for the cleaning of laser and related industries, semiconductor and related industries, optics, electron microscope, magnetic read-write head, video head and magnetic head, and the wiping of corners, gaps and planes in precision devices and other industries. The cotton swab head is made of various materials and shapes, which can adapt to the wiping of various solvents. At present, there are cloth heads, sponge heads, non-woven cloth heads and non-woven fabrics on the market. Dust free cotton swabs are essentially different from ordinary cotton swabs. The swab head is made of cotton. It cannot be cleaned without dust and may be scraped off during wiping. They are cleaned and packaged in the clean room. Therefore, in the high-grade dust-free environment, the wiping consumables used must be above grade 100. Ordinary cotton swabs can only be used to wipe products under normal conditions. But now, with the development of society and people's attention to safety and health, dust-free cotton swabs no longer belong to the dust-free and anti-static industry. It is also widely used in beauty industry and ordinary families. Common daily necessities. It is widely used in the beauty industry. Now beauty has become the patent of young ladies and sisters. When using skin care products for care, you must use a dust-free cotton swab. In this industry, the requirements for cotton swabs are very high, especially in some beauty and makeup industries. Dust free cotton swabs should be developed for different uses in different industries in the future. Dustless cotton swabs are indeed cleaner and more suitable for occasions with high hygiene requirements. Cotton swab manufacturers can produce all kinds of cotton swabs according to the specific requirements of users. The main differences between different types of cotton swabs are the length and material of the handle, the size, shape and material of the cotton swab head, and the retention, absorption and adsorption capacity of the solvent. Foam clinker, polyester fabric and cotton are all used to produce cotton swab heads. The tip of the swab can be machined by thermal bonding, folding or fusion welding. Some new cotton swabs have spiral tips that can wipe away more debris.

Proper use, storage and cleaning of masks are the key to maintaining their effectiveness. What are the precautions for citizens to wear masks on a daily basis: 1. Wear the mask correctly to ensure that the mask covers the mouth, nose and chin, and the nose clip is pressed tightly; 2. The mask is dirty, deformed, damaged and has peculiar smell, which needs to be replaced in time. The cumulative wearing time of each mask shall not exceed 8 hours; 3. Masks used in cross regional public transport or hospitals are not recommended to be reused; 4. Masks that need to be reused should be hung in a clean, dry and ventilated place; 5. In case of suffocation, shortness of breath and other discomfort when wearing the mask, take off the mask immediately and place it in an open and ventilated place; 6. When going out, carry a spare mask and store it in the original packaging bag or clean storage bag to avoid extrusion and deformation. Waste masks belong to other garbage disposal. The continuous demand for masks and the expanded production of masks may make hundreds of millions of masks circulate. Then these disposable masks can not be reused after wearing. What should we do to avoid new infections? In hospitals, medical waste is usually divided into black, yellow and red. Among them, domestic waste in black plastic bags, medical waste in yellow plastic bags (including infectious waste), radioactive waste in red plastic bags and other special medical waste. These used disposable masks are put into clean and sealed bags and thrown into the Yellow dustbin. Masks belong to medical waste. According to the classification catalogue of medical waste, cotton balls, cotton swabs, drainage surfaces, gauze and other dressings; Disposable sanitary articles, disposable medical articles and disposable medical devices belong to infectious waste. In addition, more masks are used outside the hospital to prevent and avoid infection. They may not be infected with the virus. How should we deal with them? In cities with strict regulations on waste classification and treatment, it is suggested to put used masks into plastic bags and other sealed bags and put the sealed bags into harmful garbage cans in accordance with the principle of prudence and from the perspective of maximizing the protection of public life and health. In city where there is no strict garbage classification, the respirator with alcohol spray can be bagged and sealed. 75% of high temperature and medical alcohol can kill COVID-19. In the new version of the mask wearing guide, key occupational groups mainly involve high-risk posts of overseas input and pollution transmission, staff of medical institutions and service personnel in public places. The first category is the high-risk personnel imported from abroad and the diffusion of pollution, focusing on the posts related to overseas cold chain food transportation, such as customs officers, cleaners, porters, drivers, etc. Strengthen protection, wear particle protective masks at work to prevent the transmission risks of economic substances, environment and people. The second category is the staff of medical institutions. In addition to the key protection of service personnel and staff in direct contact with patients or infected persons, personnel exposed to potential pollutants, such as cleaners, nurses, plumbers, laboratory staff, etc., wear anti particulate masks, and other hospital staff, such as security guards, doctors, etc. Wear a medical surgical mask or a higher level of protective mask. The third category is the service personnel in public places, such as stewardess, police, couriers, etc. in the past, they needed disposable medical masks. This revision is upgraded and strengthened. It is required to wear medical surgical mask or higher-level protective mask during work. In recent years, due to overseas tourism, entry and exit and other reasons, some places have added some new ones. At present, it has involved many fields in many cities. In order to prevent the epidemic from fighting back, people should pay attention to wearing protective masks. It has been more than two years since the outbreak. From inadequate preparation to strict control, China has invested a lot of manpower and energy, and finally achieved good results. However, in other countries, the epidemic prevention and control is not strict, resulting in very serious consequences. It can be seen from the figure that the cumulative number of deaths from the epidemic abroad is very terrible. No matter where you go or in which city, please remember to wear a protective mask to ensure your safety. In the past, few people used to wear masks when traveling. Now people wear masks for health reasons. What kind of masks do we usually use? Most of us use disposable medical masks. 1. There are many kinds of disposable medical masks, which can be used by adults and children. They are very suitable for wearing. 2. The mask is mainly composed of non-woven fabric. Its production process is strictly sterile, which can reduce people's adverse reactions when wearing. 3. It can effectively block dust, dust, particles, droplets and other substances in the air and play a good protective role. 4. It is mainly composed of three layers with good air permeability. It can prevent the mask of harmful substances from entering our respiratory system and protect users. 5. There are many kinds of medical masks, including medical protective masks, medical surgical masks and ordinary medical masks, which can be purchased on demand. With the outbreak of the epidemic, we need to wear masks every day. Have you ever observed the mask you're wearing? Most of them are medical masks, which have a good protective effect and have a good protective effect on us. Let's see. 1. There are many kinds of medical masks. We usually use medical protective masks and kf94 masks. In addition, medical surgical masks and ordinary medical masks are also included. Disposable products are disposable. You can't use it! Disposable masks should not be reused, because the protection time of disposable masks is limited, generally about 4 hours. If it is reused for more than 4 hours, the protective effect will be reduced, which is not conducive to the prevention of infectious diseases. If the disposable mask is worn many times, it is relatively harmful. First, the filtration efficiency will be greatly reduced, and the droplets in the air cannot be effectively separated, which greatly reduces the effect of preventing virus infection. Then wear it many times. If disinfection is not timely, cross infection is easy to occur, which is very dangerous.

Dustless cotton swabs are essential items in the process of industrial production. Dustless cotton swabs need to be used for wiping equipment or disinfection and sterilization. Dustless cotton swabs have slowly replaced pure cotton swabs. Dustless cotton swabs can deal with higher environmental cleaning above level 100, and are harmless to the environment and health. The nylon swab can be used repeatedly as a cotton swab, which can not only reduce the intensity of wear-resistant cloth, but also reduce the intensity of dust-free cloth in the industrial environment. If you need to wipe precision instruments, it is recommended to use ultra-fine fibers, which not only wipe carefully, but also not easy to leave dust and debris. The surface of his cotton swab is smooth and dust-free. If you need to wipe optical fiber equipment, you need to use professional cotton swabs and fine fibers woven by machines. This kind of fiber is very durable and can be specially used to wipe optical fiber, which can be seen from the degree of cleanliness. If the surface of the instrument is too dirty, it can be wiped with knitted polyester. The wiping ability of dust-free cotton swab knitted polyester is general, but it can absorb more garbage and waste, and its gap is deep, so it can accommodate more garbage. 1. The overall packaging of the cotton swab is better, because the cotton swab manufacturer pays attention to packaging, which is equivalent to putting protective clothing on the purified cotton swab. 2. The color of cotton swabs should be uniform, because some cotton swab manufacturers will mix different quality purification cotton swabs together in order to save costs. 3. You can call the seller and mail the samples to test or test the use effect in advance. 4. If the price of a dust-free cotton swab is far lower than the market price, it is certain that there must be problems in the workmanship and quality of the product. Because there is no free lunch in the world. Consumers feel that they have taken advantage of cheaper products. In fact, it is at the cost of quality, and the gains outweigh the losses. Therefore, when purchasing dust-free cotton swabs, we should not simply pursue low price, but also consider the performance, quality and other factors of the products. Therefore, when you decide to purchase dust-free cotton swabs, don't just look at the price of dust-free cotton swabs. Analyze their cost performance and select a dust-free cotton swab manufacturer that meets your requirements. Precautions for dust-free purification cotton swab 1. After the sterile cotton swab is used up, the outer package shall be sealed. Once the outer package is opened and properly stored, it can remain sterile within 24 hours. If it exceeds 24 hours, it will no longer be sterile due to the pollution of bacteria in the air. 2. Disinfection only kills pathogenic microorganisms, and sterilization can kill the seeds and spores of bacteria. The cotton swab has bacterial spores, and the disinfectant can't help it. Even the disinfectant may be contaminated. At this time, not only can it not disinfect, but it may cause infection. Therefore, the cotton swab that is no longer sterile should not be used on the wound. 3. Do not place cotton swabs in the ear canal. Taking out earwax with a cotton swab may make the earwax fall off from the original place and pile up in a pile, which is easier to go deep into the ear canal and block the ears, resulting in pain, hearing problems, tinnitus or dizziness. If necessary, it may also need drug treatment. In addition, the cotton swab may enter too deep and cause rupture of the eardrum.

Mask is a kind of sanitary product, which generally refers to the appliance worn on the mouth and nose to filter the air entering the mouth and nose and prevent harmful gases, odors and droplets from entering and leaving the mouth and nose. It is made of gauze or paper. The mask has a certain filtering effect on the air entering the lungs. When respiratory infectious diseases are prevalent, the working effect in dust and other polluted environment is very good. The outer layer of the mask often accumulates a lot of dust, bacteria and other dirt in the outside air, while the inner layer will block the exhaled bacteria and saliva. Therefore, the two sides cannot be used alternately, otherwise the dirt polluted by the outer layer will be directly attached to the face and will be inhaled into the human body and become a source of infection. When the mask is not in use, it should be folded, put it in a clean envelope, and fold the side close to the mouth and nose inward. Don't put it in your pocket or hang it around your neck. Dust prevention efficiency. The dust blocking efficiency of the mask is based on its blocking efficiency against fine dust, especially respiratory dust below 2.5 microns. Because the dust with this particle size can directly enter the alveoli, it has a great impact on human health. The dustproof principle of gauze mask is mechanical filtration, that is, when dust collides with gauze, it will block some large particles of dust in the gauze through layers of barriers. For some small dust, especially dust below 2.5 microns, enter the respiratory system through gauze mesh. The filter material of the dust mask is activated carbon fiber felt pad or non-woven fabric. In the process of filtering air through this filter material, it will block inhalable dust less than 2.5 microns.

Under the current development of cleaner production conditions, with the higher and higher requirements for dust-free grade, dust-free wiping products are also sought after by users. Indeed, dust-free wipes can bring unprecedented "cleanliness" to cleaner production. At present, the common dust-free rags with good effects are dust-free rags and dust-free rags, which can no longer meet the needs of our industry for micro pollution control. However, there is a very easy-to-use micro pollution wipes, that is, dust-free cotton swabs, also known as dust-free wiping cloth. It can effectively remove small particles on products or product carriers, and has become the best tool. Precision testing. However, there are many kinds of dust-free cotton swabs. How should users choose the most suitable dust-free cotton swab? Let's take a look at the material classification of dust-free cotton swabs: Dust free purification cotton swab (also known as dust-free wiping stick) is essentially different from ordinary cotton swab: The material of ordinary cotton swab head is cotton. It cannot be cleaned without dust and may be scraped off during wiping; It can only be wiped with products in ordinary environment, such as ordinary medical cotton swabs, beauty cotton swabs, etc; The materials of dust-free cotton swab head / wiping rod are divided into sponge head and cloth head, which have been cleaned and packaged in the dust-free room. Therefore, the wiping consumables used in the advanced dust-free environment must reach more than 100. Only the dust-free cotton swab can meet the requirements, such as huby purification cotton swab, which is mainly used to wipe accessories and dust in HDD, PCB, FPD, lens, semiconductor and other industries.

Cloth ends can be divided into the following types according to different fabrics and their functional properties: A: knitted nylon cloth (super wear-resistant) B: Knitted microfiber (wipe fine dust, average wear-resistant)) C: woven microfiber (fiber wiping specialty) d: knitted polyester (longitudinal grain on the cloth surface, deep gap, can accommodate more dirt). Dust-free cloth ends above cotton swabs can be cleaned in class 100 rooms, Suitable for electronic use. 2. The sponge head can be divided into the following two types according to the density and chip removal of the sponge: perforated Pu sponge, 100ppi (PPI -- port per inch, refers to the number of holes per inch, the more the number), the finer the sponge, the lower the sponge density, easy to drop chips, but the water absorption speed is fast, which is suitable for medical use; b: Perforated Pu sponge, 400-500ppi, has higher density than 100ppi sponge, is not easy to break, and has high dust-free grade.

Different dust-free cotton swabs are used according to their own needs to ensure the cleaning effect of products. 2. Although the cotton swab is small in size, its cleaning ability is very powerful. When using the previous cotton swab, the cotton dust will fly around and affect its cleaning ability. Now, with the higher and higher requirements for dust-free in all walks of life, the function of cotton swabs is becoming more and more perfect. People invented dust-free cotton swabs.

After sterilization and purification for many times, the dust-free cotton swab has good cleaning effect. It can be used with most cleaners to thoroughly clean the product. For example, the head of the sponge head dust-free cotton swab is composed of several layers of sponge fiber, which not only removes stains quickly, but also has high strength. Because the high-quality plastic rod has anti-static function, it can effectively remove the adhesion of various dust. The performance of dust-free cotton swab reflects the characteristics of high strength, flexibility, environmental protection and easy disposal of waste products. Because of its good wiping buffer ability and good liquid water locking ability, it is widely used in microcomputer, microcomputer cleaning, hard disk pollutant cleaning, optical lens surface treatment, electronic product cleaning and so on. Products. In addition to industrial applications, in daily life, it is also used by more and more consumers to clean daily necessities with its low price and high efficiency. 4. Dustless cotton swabs are essential items in the process of industrial production. Clean cotton swabs are required for wiping equipment or disinfection and sterilization. Dust free cotton swabs gradually replace pure cotton swabs. The above-mentioned high-level environment is clean and harmless to the environment and health. Dust free cotton swabs are ideal for industrial environments. Using knitted nylon cloth as cloth head can not only be used repeatedly, but also reduce wear resistance, reduce cotton swab investment, environmental protection and sanitation. If you need to wipe the precision instrument, it is recommended to use superfine fiber, which is not only delicate, but also not easy to leave dust and debris. Wipe the smooth surface of the instrument with a dust-free cotton swab, and its wear resistance is obviously reduced. If you need to wipe optical fiber equipment, you need to use professional cotton swabs and machine woven fine fibers. This kind of optical fiber is very durable and can be used to wipe the optical fiber with obvious cleanliness. If the surface of the instrument is too dirty, it can be wiped with knitted polyester. Knitted polyester has a general wiping ability with a dust-free cotton swab, but it can absorb more garbage and waste, and its gap is very deep, so it can hold more garbage 2. How to identify the quality of dust-free purification cotton swabs: 1. The overall packaging of cotton swabs is better, because cotton swab manufacturers pay attention to packaging, which is equivalent to wearing protective clothing on purified cotton swabs. 2. The color of cotton swabs should be uniform, because some cotton swab manufacturers will mix different quality purification cotton swabs in order to save cost. 3. You can call the seller and mail samples for advance test or check the use effect. 4. If the price of dust-free cotton swabs is far lower than the market price, there must be a problem with the workmanship and quality of the products. Because there is no free lunch in the world, consumers may feel that they are taking advantage when buying, but in fact, it is at the cost of sacrificing quality, and the gains outweigh the losses. Therefore, when purchasing dust-free cotton swabs, do not simply pursue cheap prices, but also consider product performance, quality and other factors.
