Medical surgical mask: YY0469-2011

Medical surgical masks must be produced in accordance with the medical standard YY0469-2011. If the enterprise standard set by the enterprise meets or even exceeds the requirements of YY0469, it can also be printed on the outer packaging of the mask. It still depends on the name of the mask and the content of the enterprise standard for identification). Surgical masks are mainly used for invasive operations such as surgery and tube placement in hospitals, and key monitoring and control departments generally require such masks.

YY0469 has the requirements for bacterial filtration performance of surgical masks. Generally, the filtration efficiency of non-oily particles should be more than 30%, and the filtration efficiency of bacteria should be more than 95%. (Note that this is not the meaning of N95. Do not confuse with medical protective masks. ) In addition, medical surgical masks also have requirements for the permeability of synthetic blood (which can be simply understood as impermeability). When companies make them, they generally divide the masks into three layers: the internal water absorption layer, the middle filter layer, and the outer waterproof layer. , Each layer has a special role.
