What is a medical surgical mask?
According to performance characteristics and scope of application. Medical masks can be divided into: medical protective masks, medical surgical masks, and ordinary medical masks.
Medical surgical masks are suitable for basic protection of medical staff or related personnel. As well as protection against the spread of blood, body fluids and splashes during invasive operations. The protection level is medium, with certain respiratory protection performance. Mainly in a clean environment with a cleanliness level of 100,000 or less. It is worn when working in the operating room, nursing patients with weakened immune function and performing body cavity puncture operations.
Medical surgical masks can block most bacteria and some viruses, and can prevent medical staff from being infected. At the same time, it can also 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. Disposable medical surgical masks should also be issued to suspicious respiratory patients. Prevent the threat of infection to other hospital personnel and reduce the risk of cross-infection. However, the effectiveness of preventing infection is not as good as medical protective masks.
