Classification of medical masks

Medical masks are a kind of medical protective textile, which is mostly made of one layer or multilayer nonwoven fabric. The main production process includes melting spray, spinning, hot wind or needle injection, which has the utility of resisting liquid, filtering particulate matter and bacteria.

According to the performance characteristics and scope of application, medical masks can be divided into: medical protective masks, medical surgical masks, and ordinary medical masks. Dalian Musk Medical Equipment Technology Co., Ltd

① Medical Protective Mask (as we often call N95,KN95 masks)

Medical protective masks are applicable for the protection of airborne respiratory infectious diseases by medical staff and related staff. It is a dense self-absorption filter medical protective device with high level of protection, especially suitable for patients with respiratory infection exposed to air or close droplets in diagnosis and treatment activities. Can filter the particles in the air, block the droplets, blood, body fluid, secretions droplets, etc., belongs to the disposable product. Medical protective masks can prevent most bacteria, viruses and other pathogens. WHO recommends medical staff to use anti-particulate protective masks to prevent virus infection in the air of the hospital.

Medical protective masks meet the Technical Requirements of GB19083-2003《 Medical Protective Masks. The important technical indicators include non-oil particle filtration efficiency and airflow resistance. Dalian Musk Medical Equipment Technology Co., Ltd

② medical surgical mask

Medical surgical masks are applicable to the basic protection of medical personnel or relevant personnel, as well as the protection to prevent the spread of blood, body fluids and sputters during invasive operation. Moderate level of protection and have certain respiratory protection performance. Mainly in the clean environment within 100,000 level of cleanliness, operating room work, care for patients with low immune function and body cavity puncture and other operations to wear. Medical surgical masks can block most bacteria and some viruses, prevent medical staff from being infected, and also prevent the direct discharge of microorganisms carried in their breath, posing a threat to patients undergoing surgery. Medical surgical masks require a bacterial filtration efficiency of more than 95%. For suspected respiratory patients should also issue disposable surgical masks to prevent an infectious threat to other personnel of the hospital and reduce the risk of cross-infection, but the effect of avoiding infection is not as good as medical protective masks.

Compliance with the YY0469-2004《 Technical Requirements, important technical indicators include filtration efficiency, bacterial filtration efficiency and respiratory resistance.

③ general medical mask

General medical masks are used to block sputters in the mouth and nasal cavity, and can be used for disposable health care in general medical environments, with the lowest level of protection. It is suitable for general health care activities, such as sanitary cleaning, liquid dispensing, sheet cleaning, or the blocking or protection of particles beyond pathogenic microorganisms such as pollen.

Compliance with the relevant registered product standards (YZB), generally lacks filtration efficiency requirements for particles and bacteria, or for particles and bacteria are lower than medical surgical masks and medical protective masks. Only 20.0% -25.0% protective effect for particles and bacteria, can not effectively prevent pathogens from respiratory invasion, not used for clinical invasive operation, particles and bacterial viruses, limited to a certain mechanical barrier on dust particles and aerosol.
