1. Medical surgical mask refers to the medical mask commonly used in the environment with risk of body fluid and blood splashing, which can block blood and body fluid from passing through the mask to pollute the wearer. At the same time, the filtration efficiency of bacteria is more than 95%, but the filtration efficiency of particles is limited and mostly rectangular design, and the tightness of the mask is not as tight as that of the mask. Common surgical masks include bandage type and ear hanging type.
2. There are many names of medical masks at ordinary level. Those with no words of protection or surgery on the name are all medical masks at ordinary level. This level of masks is not required to have blocking effect on blood, nor to put forward requirements for tightness, so they are only used for wearing in ordinary medical environment. Most of the common medical masks are ear mounted, and their appearance is similar to that of ear mounted surgical masks.
