How long can medical protective masks be used?

In fact, the use of protective masks is not only used by doctors, but also by practitioners in many professions. Medical protective masks are also used. For example, some scientific researchers will wear medical protective masks when conducting experiments on viruses or bacteria in the laboratory. Some friends who are allergic to pollen also need to wear medical protective masks when going out. Other workers who need to come into contact with toxic chemical gases also need to use medical protective masks.

Medical protective masks refer to self-priming filtering dust-proof medical protective masks that can filter particles in the air and block droplets, blood, body fluids, secretions, etc. This is a mask that can prevent infection from airborne infectious agents with a diameter of ≤5μmg or diseases transmitted through droplets at close range (≤1m). The use of medical masks includes fit testing, training, model selection, medical handling and maintenance.

The medical protective mask consists of a mask face and a tension strap. The mask face is divided into three layers: inner, middle and outer. The inner layer is ordinary sanitary gauze or non-woven fabric, the middle layer is an ultra-fine polypropylene fiber melt-blown material layer, and the outer layer is a non-woven fabric or an ultra-thin polypropylene melt-blown material layer. This high-efficiency medical protective mask is hydrophobic and breathable, and has a significant filtering effect on tiny virus-carrying aerosols or harmful dust. The overall filtering effect is good. The materials used are non-toxic and harmless and it is comfortable to wear.

Protect the human body from the harm of suspended particles in the air. Suitable for protection of medical staff in infectious disease areas. Suitable for protection of virus laboratory personnel. Protection of all types of personnel during epidemics of infectious diseases. Toxic chemicals, mining workers, and people with pollen allergies. Individual soldier protection against military biological and chemical weapons.

Medical protective masks are said to have better protective effects than ordinary disposable masks, but the price of medical protective masks is relatively higher than that of disposable masks. Even so, if we have an infectious disease or need to come into contact with people with infectious diseases, we must wear a protective mask during the operation to better protect our bodies from the disease.
