Cleanroom SwabCleanroom cotton swabs are a kind of clean room cleaning consumables produced in the clean room. And the cleanroom purification cotton swabs must strictly comply with the various production requirements of the clean room, but due to the difference in material and production process, they are also divided into different grades. Its grade is compatible with the grade of clean room.Flocked swabThe flocked swab is composed of a handle, a connecting rod and a sampling head. The long handle is easy to hold and can be adjusted back and forth while holding it, which is suitable for different people. The soft and slender connecting rod can effectively protect the sampled tissue from damage. The sampling head is composed of fluff and viscose, which is harmless to the human body and microorganisms, and can maximize the collection and release of samples. Flocking swabs and supporting collection tubes and transport tubes constitute the sample collection system!DifferenceMedical nylon flocked swabs are specially used for sample collection, and cotton swabs can also be used for sample collection, but the number of samples collected and the collection effect of the two cannot be compared. Nylon flocked swabs are used in the medical industry, such as collecting human mouth, nose, throat, cervix and other liquid microorganisms, DNA, viruses, bacteria, etc., while cotton swabs are used in industrial cleaning, such as wiping camera lenses, which are very small The gap, hard disk, magnetic head, microscope, instrumentation, optical and optoelectronic products, printer head.Shenzhen Cleanmo Technology Co., Ltd., a manufacturer of medical consumables: sampling swabs, disposable sampling swabs, sterile sampling swabs, DNA, virus sampling swabs, throat swabs, nasal swabs, oral sampling swabs Swabs, flocked sampling swabs, cervical sampling swabs, cell preservation solution, cell culture medium, disinfection swabs, cotton swabs, applicators, biological sampling cotton swabs and other products.

If you see someone in the news footage pushing a long swab into your nose and is undergoing a nucleic acid test for the new coronavirus, then you may be wondering if the process will be painful. I think the answer depends on your personal pain tolerance, but-having personally performed a flu swab test very similar to the coronavirus test-I would say, let your nose be "weird" and "discomfort" more than "pain" . "To test the new coronavirus nucleic acid test, a sample of secretions needs to be obtained from the nostril to the entire nasal passage that intersects the back of the throat. To obtain these secretions, medical staff will use a professional nasal swab. The clinician quickly inserts the cotton swab into the nasal cavity, then pushes it all the way to the back of the throat, and then rotates and removes it. The whole process only takes a few seconds to complete.However, the fact that it is fast does not mean that it is not uncomfortable. Along the path, the swab will stimulate the sinus tissue or activate multiple nerves. In fact, when the swab stimulates the lacrimal nerve, the procedure does bring tears to your eyes. The swab may also instantly itch the vagus nerve, causing the vomiting reflex.I won't say these feelings are painful-just annoying or uncomfortable.Don't postpone the new coronavirus swab test because you are worried that the procedure will be unpleasant. If your condition worsens, early diagnosis allows early medical intervention. Also, if you have coronavirus, you need to know about it so that you can self-quarantine and avoid spreading the virus to your loved ones in your family and anyone else you meet.Therefore, if you have symptoms of coronavirus, such as fever and dry cough, you should get rid of the fear of long flocked swabs and then take the test.

Oral swab is just similar to our daily cotton swab, but it is a product used to extract DNA. The swab is stretched into the cavity, hung back and forth on the inner wall of the oral cavity many times, packaged and sent to the testing agency for testing.The principle is to collect oral epithelial mucosal cells, and complete DNA identification by detecting the DNA in these cells.The oral swab has developed a product that collects microbial DNA from saliva. This is an integrated system update that can collect, stabilize, transport, and purify DNA from saliva, providing a painless and risk-free new way to collect microbial DNA for disease control and prevention.Oral swabs have the same test data as blood. They are painless and very scientific and credible. Many gene companies are recommending oral mucosa. A large number of clinical trials of oral swabs in foreign countries have shown that: compared with ordinary sterile swabs, nylon flocked swabs have a better effect on the collection and transportation of clinical biological samples, especially for those who cannot be sent for inspection in time, and the time is too long. This is especially true for long samples.Sampling swabs can be divided into throat swabs, oral swabs, DNA swabs, and cervical swabs according to different uses, and can be used by various laboratory testing centers and hospitals.How to use oral swabs:1. 30 minutes before sampling, do not eat, smoke, drink, etc.(1) Prepare a glass of water, drink about 50ml of water and rinse your mouth for about 10 seconds, then vomit;(2) Repeat the above steps 2-3 times.2. Sampling(1) Tear open the outer packaging of the oral swab and take out the oral swab carefully (note: the swab part should not be touched by the hand during the whole sampling process).(2) Hold the handle, extend the swab into the left mouth, make the head of the swab fully contact the mucous membrane of the left cheek/left upper and lower gums, rub it up and down with the strength of brushing, while rotating the swab Fully contact the swab head with the oral mucosa, repeat this action for 1 minute.(3) Use the same method to sample the second swab on the mucosa of the right cheek/right upper and lower gums.(4) Put the swab stained with oral exfoliated cells in a clean and ventilated place for at least one hour until it is dry, and put it back into the collection tube to complete the sampling.3. After sampling(1) After filling in your name on the label of the collection tube, put the collection tube into a ziplock bag, and then register your relevant information on the front label of the ziplock bag: name, gender, age, date of collection.(2) Please carefully fill in the relevant information on the registration form for submission. If you choose to test anonymously, please fill in the barcode number on the registration form for inspection.(3) Send the ziplock bag with the collection tube and the registration form for inspection to the testing agency at room temperature.

According to a CNN report, the FDA has approved the emergency use of the first over-the-counter home new coronavirus detection system. Users over 18 can buy it and use it at home.The FDA said that the new coronavirus detection system produced by U.S. Holding Laboratories which allows people over the age of 18 to purchase it. Users can collect nasal swab samples at home and then submit them to U.S. Holding Laboratories for testing. The test result will be notified to the user by phone or email.In November, the FDA has approved the emergency use of the first home rapid detection tool for new coronaviruses produced by the California manufacturer "Lucilla Medical", which can give test results within 30 minutes, but requires a prescription before it can be purchased.
