Medical masks are mainly used by medical staff to protect themselves and others, especially when there is severe environmental pollution or a sudden medical infectious disease . It is recommended to wear them when necessary.
Medical masks are suitable for medical staff and related workers for the protection against airborne respiratory infectious diseases. They are a kind of tight-fitting self-breathing filtering medical protective products with high protection level, especially suitable for wearing when contacting patients with respiratory infection diseases that are transmitted through air or close-range droplet transmission during medical treatment. They can filter out particles in the air, block droplets, blood, body fluids, and droplet micro-droplets, and are disposable products. Medical protective masks can prevent most bacteria, viruses and other pathogens, so it is recommended that medical staff use anti-particle protective masks to prevent viral infection in hospital air.
The outer layer of medical masks is a polypropylene moisture-proof non-woven fabric protective layer, which has waterproof function, thus effectively isolating droplets and preventing liquid from leaking into the mask interior; the middle layer is a high-density filtration layer, which helps protect large dust particles; the inner layer directly contacts the skin around the mouth and nose: the non-woven fabric has undergone special hydrophilic treatment, is soft and breathable; both sides are equipped with sturdy and flexible nose straps to form a good sealing effect. During an infectious disease outbreak, the Ministry of Health will also recommend that the public wear medical masks to protect themselves. These masks are relatively loose and can completely cover the nose and mouth. However, most surgical masks cannot effectively filter small particles in the air and cannot prevent leakage at the edges of the mask when the user inhales.
