China Surgical Mask Manufacturers introduced that medical masks are classified according to their performance characteristics and scope of application:

1. Medical protective masks are suitable for the protection of medical staff and related staff against airborne respiratory infectious diseases. It is a kind of close-fitting self-priming filtering medical protective equipment with high protection level, especially suitable for diagnosis and treatment activities. Wear it when you are in contact with patients with respiratory tract infections that are transmitted through the air or through droplets at close range. Can filter particles in the air,It blocks droplets, blood, body fluids, secretions, etc., and is a one-time use product.

2. Medical-surgical masks are suitable for basic protection of medical staff or related personnel, as well as protection to prevent the spread of blood, body fluids, and splashes during invasive operations.

Mainly in a clean environment with a cleanliness level of less than 100,000, working in the operating room, nursing patients with immunocompromised function, and performing body cavity puncture Wear it while waiting for the operation. Medical-surgical masks can block most bacteria and some viruses, prevent medical staff from being infected, and at the same time prevent the direct discharge of microorganisms carried in the breath of medical staff, posing a threat to patients undergoing surgery. Medical-surgical masks require a filtration efficiency of more than 95% for bacteria. For suspicious respiratory patients, a disposable medical external should also be issued. Medical masks prevent the threat of infection to other hospital personnel and reduce the risk of cross-infection, but the effectiveness of preventing infection is not as good as medical protective masks.

3. Ordinary medical masks are used to block sprays from the oral cavity and nasal cavity and can be used for one-time hygiene care in ordinary medical environments, with a low level of protection. It is suitable for general health care activities, such as sanitation, liquid preparation, cleaning bed units, etc., or barrier or protection of particles other than pathogenic microorganisms such as pollen.
