Speaking of medical masks, I believe that many people are not unfamiliar. Medical surgery and dressing change and other operations need to wear, but some packaging although it is written with this name, it is worthy of the name.

Generally speaking, medical medical medical masks must comply with YY 0469-2004 "technical requirements for medical medical masks". The important technical objectives include filtration efficiency, bacterial filtration efficiency and respiratory resistance

1. Filtration efficiency: under the condition of air flow rate (30 ± 2) l / min, the filtration efficiency of sodium chloride aerosol with aerodynamic median diameter of (0.24 ± 0.06) μ m should not be less than 30%;

2. Bacterial filtration efficiency: under regular conditions, the filtration efficiency of Staphylococcus aureus aerosol with uniform particle diameter of (3 ± 0.3) μ m is no less than 95%;

3. Respiratory resistance: under the condition of filtration efficiency flow, the inspiratory resistance does not exceed 49 PA and the expiratory resistance does not exceed 29.4 PA.

Medical protective mask is suitable for all invasive operations, which need to stop the splashing of blood and body fluids. At the same time, the qualified medical protective mask should have a blocking effect on the small amount of aerosol and smoke particles caused by electric cutting and electrocoagulation during operation.

Attention: ear hanging type can't be used as medical protective mask during operation.

Due to the long time-consuming operation in internal medicine, the task personnel need to stop the necessary verbal communication. In order to avoid the "sunset scene" (referring to the droplet caused by the operator's speech, cough, etc.) falling in the operation along the lower edge of the mask, if lighting is used, If the knot is tied to the mandible, when wearing the operating clothes and during the operation, the internal medicine mask must be of the lace up type, and it is not allowed to tie the knot in the lower jaw, It is easy to clean the neckline). The two ties should be identified and tied at the neck and the back of the head. At the end of wearing the mask, make sure that the nose clip is molded and the lower part of the mask fits the lower jaw tightly.
