Ordinary medical masks are used to block the spray from the mouth and nasal cavity. They can be used for disposable sanitary care in the ordinary medical environment with the lowest protection level. Suitable for general health care activities, such as sanitary cleaning, dosing, cleaning bed units, etc., or the blocking or protection of particles other than pathogenic microorganisms such as pollen.

Studies have shown that, within a predetermined range, surgical masks are not worse than N95 masks in preventing flu. Zhong Nanshan, the leader of the high-level expert group of the National Health and Health Commission against SARS, also said, “Actually, it is not necessary to wear N95 masks. General masks can block most of the virus-borne droplets from entering the respiratory tract, preventing new coronavirus It ’s useful to wear a mask. ”So if you ca n’t buy a N95 mask, you can choose a general surgical mask.

At present, there are many types of masks on the market. The names of the masks include medical, protective and other words, which may not have the described effect. How do we judge?

Regardless of whether it is a medical protective mask or a surgical medical mask, ordinary medical masks are medical devices and are included in the management of medical devices. The production and management of medical devices in China is very strict. Masks for medical device production license and medical device product registration certificate.

Not all masks marked with N95 can protect against germs. There are two types of N95 masks, one is a bio-proof mask, that is, a N95 medical protective mask, and the other is a dust-proof mask.

They have the same protection level and pass the N95 level test, but the protection standards are different, and the objects to be protected are also different. The standard for biological masks is GB19083-2010 “Technical Requirements for Medical Protective Masks”, which is used in the medical and health industry, such as epidemic prevention stations, hospitals, and disease control centers. The standard for dust masks is GB2626-2006 “Respiratory Protective Products Self-Suction Filtering Anti-Particulate Matter Respirator”, which is used in industries such as coal mining, petroleum processing, mining and other industrial and mining enterprises. For new coronaviruses, a biologically-resistant N95 medical protective mask should be selected.
