Surgical mask refers to the equipment that doctors wear on the mouth and nose during surgery to filter the air from the nose and mouth, so as to prevent harmful gases, odors and droplets from entering and leaving the wearer's mouth and nose. Especially in the prevention and control of respiratory infectious diseases play an important role.
Surgical masks generally consist of the following materials: Main filter material: such as polypropylene melt-blown cloth. Other materials: metal (used for nose clip), dye, elastic material (used for mask strap), etc.
Surgical masks can be divided into medical protective masks, medical surgical masks and ordinary medical masks according to their performance characteristics and scope of application.
1.Medical protective mask
The mask is composed of a mask body and a tension band. The mask body is divided into inner, middle and outer layers. The inner layer is common sanitary gauze or non-woven fabric, the middle layer is super-fine polypropylene fiber melt-blown material layer, and the outer layer is non-woven or ultra-thin polypropylene melt-blown material layer.
This high-efficiency medical protective mask has strong hydrophobic permeability, and has remarkable filtering effect on tiny viral aerosols or harmful fine dust. It has the function of filtering bacteria, blocking liquid spatter with pressure and protecting the breathing safety of medical staff.
2.Surgical mask
The mask is divided into three layers. The outer layer can block water and prevent droplets from entering the mask. The middle layer has a filtering effect, can block >90% of 5μm particles; The inner lining near the nose and mouth is used for moisture absorption. Medical surgical masks are suitable for the basic protection of medical staff or related personnel, as well as the protection to prevent the transmission of blood, body fluids and splashes during invasive operations. They have strong resistance to bacteria and viruses, and can also be used to prevent influenza.
3.Common medical mask
The filtering efficiency of particles and bacteria is lower than that of surgical masks and medical protective masks when using two-layer nonwoven fabric as filter material. Mainly in order to prevent infection between doctors and patients or medical staff inhaled bacteria in the environment and be infected, the protective effect of pathogenic microorganisms is also relatively limited.
Three principles of surgical mask selection:
1.Dust blocking efficiency of masks

The dust blocking efficiency of respirator is based on its blocking efficiency of fine dust, especially respirable dust less than 5μm.
