Medical protective mask
Medical protective masks refer to self-absorbent filtering dust-proof medical protective articles that can filter the particles in the air, prevent the transmission of certain respiratory infectious microorganisms, and block droplets, blood, body fluids, secretions, etc.
Medical protective mask A mask capable of preventing infection through air-borne diameter ≤5μmg infectious factor or close-range (≤1m) contact with droplet-borne diseases. The use of medical masks includes tightness testing, training, model selection, medical handling and maintenance.
Composition and function
The medical protective mask is composed of a mask face and a tension band. The face mask is divided into inner, middle and outer layers. The inner layer is ordinary sanitary gauze or non-woven fabric. The middle layer is a superfine polypropylene fiber meltblown material layer and the outer layer. Non-woven fabric or ultra-thin polypropylene meltblown material layer. This highly effective medical protective mask is highly hydrophobic and breathable, and has a significant filtering effect on tiny virus aerosols or harmful dust. The overall filtering effect is good, the materials used are non-toxic and harmless, and they are comfortable to wear.
It can prevent infections caused by airborne diameter ≤ 5μmg infectious agents or close-range (≤ 1m) exposure to droplet-borne diseases. The particle filter efficiency of the mask filter should be no less than 95%, and the protection level is high.
Scope of application
Medical protective masks are better protective equipment. It is recommended to wear them when there is serious environmental pollution or medical infectious diseases (such as respiratory infections).
☆ Individual protection of military biochemical weapons
Dimensions of close-fitting arch mask: horizontal diameter is not less than 14cm, and vertical diameter is not less than 14cm .
Important technical indicators
Including non-oily particle filtration efficiency and airflow resistance.
(4) Be sure to fully open the mask to minimize the number of layers used during breathing.
How to wear ear-hung masks
(3) Gently pinch the nose clip to prevent air from entering.
