The medical protective mask with the structure has the advantages of simple structure, low cost and the like, but has certain defects in the using process, and particularly has more remarkable defects in the using process in the period of epidemic respiratory infectious diseases. Specifically, the method comprises the following steps:

firstly, the existing medical protective mask can effectively cut off the air transmission channel of pathogens, but the main transmission paths of a plurality of pathogens are not only limited to air transmission but also include contact transmission, and obviously, the existing medical protective mask can 'fail' to the contact transmission of the pathogens; more importantly, pathogens in the air can be adsorbed in the medical protective mask during use, and the medical protective mask can be easily contacted with the pathogens during the process of taking off the mask by a user, namely the probability of contact transmission can be increased to a certain extent during use of the medical protective mask; although the risk of infection can be reduced by means of protective means such as thorough cleaning or disinfection treatment of hands after the mask is removed, the protective means is not provided in many cases;

secondly, in the epidemic period of respiratory infectious diseases, a large amount of pathogens often exist in the used medical protective mask, theoretically, the medical protective mask should be treated in a medical waste mode, and when the medical protective mask does not have the treatment conditions, the medical protective mask should be disinfected as necessary and then discarded to prevent secondary pollution; however, for ordinary people, the medical protective mask is influenced by factors such as self quality, epidemic prevention consciousness, thought consciousness or treatment condition limitation, the used medical protective mask is directly discarded as ordinary garbage, pathogens in the medical protective mask are bred and continuously transmitted through other ways, and great potential safety hazards exist; especially, when the epidemic situation is serious, the consumption amount of the medical protective mask is huge, and the medical protective mask which is directly discarded without being processed can cause serious pollution, which is not beneficial to the prevention and control of the epidemic situation.

Thirdly, after the medical protective mask reaches the service life, the medical protective mask does not have the expected protective effect any more, so that the medical protective mask does not have the repeated use value any more, but the existing medical protective mask usually does not have a destroying mechanism which is easy to operate, the destroying is troublesome, and the contact infection is easily caused by improper operation, so that a plurality of used protective masks are discarded in a perfect form, and the risk of repeated use exists; particularly, when respiratory infectious diseases are pandemic, the protective mask is in shortage as one of important epidemic prevention substances, and under the drive of benefits, lawless persons are not rare in the case of recycling, processing and re-selling the waste protective mask, so that the generated safety problem is extremely severe, and the situation brings extremely adverse influence on the prevention and control work of epidemic situations.

Fourth, present medical protective facial mask is ear-wearing type usually, and the gauze mask face body both sides are connected with the ear area promptly, and the ear area is thinner elastic cord usually, and protective facial mask wears the in-process ear area great to the oppression effect of ear, brings certain discomfort for the user, if wear the gauze mask for a long time, the ear area can cause the hindrance to the blood circulation of ear, causes comparatively serious health problem even.
