Can filter particles in the air and block droplets of spray, blood, body fluid, secretion and the like, and belongs to a disposable product. The medical protective mask can prevent most pathogens such as bacteria, viruses and the like, and the WHO recommends that medical personnel adopt the protective mask for preventing particles so as to prevent virus infection in air of hospitals.

The medical surgical mask meets the standard of YY 0469 plus 2004 technical requirements for medical surgical masks, is a mask worn by medical workers during work and generally comprises a mask body and a tightening belt. The used materials are nontoxic and harmless and are comfortable to wear. The medical device is mainly used for medical environments with high requirements such as medical clinics, laboratories and operating rooms, and has relatively high safety coefficient. The medical surgical mask can block most bacteria and partial viruses, can prevent medical staff from being infected, and can prevent microorganisms carried in the breath of the medical staff from being directly discharged to threaten patients who are subjected to operations. The medical surgical mask requires a filtering efficiency of more than 95% for bacteria. The disposable medical surgical mask is also distributed to suspicious respiratory patients, so that the infection threat to other personnel in hospitals is prevented, and the cross infection risk is reduced. In daily life, it can be used for preventing transmission of infectious diseases such as influenza and respiratory system.

Since the SARS outbreak in 2003, respiratory infectious diseases such as influenza A, influenza B, etc., including pneumonia caused by this new coronavirus, have seriously harmed national health and caused enormous economic losses. The virus can be spread between people through oral liquid, sneeze and contact, and part of virus has the characteristics of long retention time and long delivery distance in the air, and can be directly inhaled into the bronchus of human body to interfere the exchange of lung gas so as to cause cross infection.

In the existing protective measures, the mask is worn by a convenient, effective and economic means. The mask on the market at present mainly has four kinds: common cotton cloth masks, common medical masks, disposable medical protective masks (N95 or FFP2 and above) and disposable medical surgical masks. If a common cotton gauze mask is used, the problems of low filtering efficiency and poor protection effect exist; although the common medical masks meet the relevant registered product standards (YZB), the common medical masks generally lack the requirements on the filtration efficiency of particles and bacteria, or the requirements on the filtration efficiency of particles and bacteria are lower than those of medical surgical masks and medical protective masks. Moreover, the existing mask cannot meet the requirement of timely reminding a user of replacement, so that the filtering efficiency is reduced and the breathing resistance is increased due to the fact that the user is used for a long time; on the other hand, frequent replacement is easily caused to the user, thereby causing unnecessary waste of resources. Furthermore, the existing mask cannot be used in different areas temporarily, but the infection severity of the isolation area, the diagnosis area and the social and family prevention area is different and should be distinguished.
