Information

The masks currently used in hospitals are medical surgical masks, which look thin and comfortable to wear, but they are also divided into three layers: from the outside to the inside are the waterproof layer, the filter layer and the comfort layer. In addition, it also meets the YY0469-2004 "Technical Requirements for Medical Surgical Masks" standard. The outermost blue layer is a waterproof layer, which prevents blood and saliva from penetrating into the mask. The innermost comfort layer is white and has a moisture-absorbing effect. Don't wear it backwards.

Medical surgical masks are usually head-worn, that is, there are four loose straps on the four corners of the mask, and these straps are tied to the neck and head. There is a piece of metal above the mask. After wearing, the mask can be shaped according to the shape of the nose and face to make it fit the face. Medical masks are highly resistant to bacteria and viruses. In daily life, they can be used to prevent the spread of infectious diseases such as flu and respiratory system, and to prevent patients from spreading the virus to others. The penetration rate of the fine dust medical mask with a diameter of 0.3um can reach 18.3%, which means the protection rate is about 81%. But for fine dust with a diameter of 5um, the protection rate can reach about 90%. But the filtration efficiency of bacteria is not less than 95%. Due to its good waterproof performance, it has a good protective effect on body fluids and saliva.

Disposable medical care masks, also known as medical protective masks, comply with GB19083-2003 "Technical Requirements for Medical Protective Masks". The mask is also divided into an inner layer, a middle layer and an outer layer. The inner layer is ordinary sanitary gauze or non-woven fabric, usually white, the middle layer is a layer of ultra-fine polypropylene fiber meltblown material, and the outer layer is non-woven. Woven fabric or ultra-thin layer. The polypropylene meltblown material layer is usually light blue. Also, be careful not to wear it backwards. This high-efficiency medical protective mask has high hydrophobicity and air permeability, and has a significant filtering effect on tiny virus aerosols or harmful fine dust. The overall filtering effect is good, the materials used are non-toxic and harmless and comfortable to wear. The filtration efficiency of fine dust particles is not less than 95%. There are also certain standards for size: the size of the central part of the expanded rectangular mask: the length is not less than 17cm and the width is not less than 17cm; the size of the closed arch mask: the horizontal diameter is not less than 14cm, and the longitudinal diameter is not less than 14cm. Medical protective masks cannot have exhaust valves. General medical masks that meet the relevant registered product standards (YZB) and have the lowest level of protection can only block spitting and spitting out of the mouth, and can be used for disposable health care in general medical environments, or health care activities in general wards, such as hygiene Cleaning, liquid distribution, cleaning beds, etc., or preventing or protecting other particles other than pathogenic microorganisms (such as pollen). The filtration efficiency of particles and bacteria cannot reach the standards of medical masks and medical protective masks. For an aerosol with a diameter of 0.3 μm, it can only achieve a protective effect of 20.0%-25.0%, and the filtration efficiency of particles and bacteria cannot meet current requirements. The required requirements cannot effectively prevent pathogens from invading the respiratory tract, cannot be used for clinical invasive operations, cannot protect particles, bacteria and viruses, and are limited to a certain mechanical barrier to dust particles or aerosols
