However, it is not clear whether it is true or false, and it is suggested that it can be checked and verified on the official website of the Drug Administration. Of course, there are more than a few brands and manufacturers that produce surgical masks, but there is less circulation on the market at present. Now that factories and express logistics have resumed operation, there should be a large number of qualified surgical mask on the shelves. Note: We usually go to public places to wear this, wearing the right can be effective protection. But not in close contact with the infected. Common medical mask image source network How to distinguish: "surgery" is not marked, only "medical", "nursing" and other words,Medical Disposable Coverall, corresponding to the standard YY/T0969-2013 Type: For example, Steady, Medtech, and the above-mentioned brands such as Haishi Hainuo all produce ordinary medical masks. Note: such as surgical mask can not achieve effective protection, in fact, the recent medical masks we bought in the city of this category. It can only be said that something is better than nothing! Disposable ordinary mask image source network How to distinguish: ordinary "anti-haze", "anti-bacterial",CE Certificate KN95 Mask, "activated carbon" and other masks have different colors, some of which are similar to medical masks in color and style, but do not have the same protective effect. Note: It is not that these masks are bad, but that they have their own uses, and they are not effective in preventing influenza. Not recommended. 4. Medical protective mask N95: Industrial dust mask Note: There are also many kinds of brands in N95 mask, such as 3m, Honeywell and other foreign brands, as well as many unknown domestic brands or manufacturers, but there are basically no medical protective masks on the market, and the current sales are basically dust-proof and anti-haze models. However, in this case, medical workers are short of special medical protective masks, 3 Ply Disposable Protective Face Mask ,Medical Full Body Coverall, usually we do not face such a severe environment, other types of N95 mask are enough. 5. What is the difference between N95 1860 and 9132 medical protective masks and other N95 industrial dust masks? N95 mask: "N" refers to unsuitable oily particles (such as cooking fume); "95" refers to 95% filtration rate under NIOS standard. N95 is not a specific product name, as long as it meets the N95 standard and passes the NIOSH review, it can be called "N95 mask". A green vegetable water protective layer is added on the outer surface of the medical protective mask to prevent slight liquid or blood splashing and penetration; and a colony bacteria standard test is added (the requirements of the hospital on the bacteria of the medical device products). What is the difference between KN95 and N95? 7. What is the validity of the mask? The one-time effective time limit is 4 hours, and the protective time limit of medical grade is 6h-8h. However, due to the different use environment, the pollution rate is accelerated, generally within 3 hours. Extended reading: There are three common types of medical masks: "medical protective masks" with the highest level of protection, "surgical mask" commonly used in invasive operating environments such as operating rooms, and "disposable medical masks" with ordinary level. The surgical mask generally has three layers, namely a waterproof layer, a filter layer and a comfortable layer from outside to inside, wherein the comfortable layer is a layer of gauze, and the surgical mask can prevent 70% of pathogenic bacteria.
Ordinary medical masks: There are many names, and there are no words such as "protection" and "surgery" on the name. This level of masks does not require a barrier effect on blood, nor does it require sealing, so it is only used in the general medical environment. Some cotton gauze masks may be made of cotton cloth, gauze, wool, canvas and velvet, etc. Because the material itself is not dense enough to prevent infection, it can only block 36% of pathogenic bacteria. Common medical protective masks are arch, butterfly, etc.; surgical mask are bandage, ear hanging, etc.; common medical masks are mostly ear hanging, which are similar to ear hanging surgical masks in appearance. In addition to a good filter material, the protective mask should also have a good shape design and nose clip design; the better the fit between the mask and the wearer's face, the better the protective effect, so as to prevent pollutants from entering the mouth and nose from the edge of the mask, especially from the gaps on both sides of the nose. Therefore, when wearing a mask, the nose clip at the bridge of the nose should be pressed tightly, and the length of the mask belt should be adjusted appropriately to make the mask fit the face as close as possible. When wearing medical masks, the appropriate level should be selected according to the type of transmission and risk of pollutants, not too high or too low. Medical protective masks with high protective grade have better protective effect, but because of the high level of filter material, good tightness and higher respiratory resistance, wearing them for a long time will increase the respiratory burden and cause dyspnea and other discomforts. Surgical mask and medical protective masks can block the pollution caused by blood and body fluid splashing,KN95 Face Mask, but if it is really necessary to block the pollution of particulate matter and pathogenic microorganisms in the air, please choose to wear medical protective masks.
