Medical Surgical Mask

Medical surgical masks are suitable for basic protection of medical personnel or related personnel, as well as protection against blood, body fluids and splashes during invasive operation. The protection level is medium and it has certain respiratory protection performance. It is mainly worn in a clean environment with a cleanliness of less than 100,000, operating in the operating room, nursing patients with low immune function, and performing body cavity puncture. Medical surgical masks can block most bacteria and some viruses, prevent medical staff from being infected, and prevent direct discharge of microorganisms carried by medical staff, which poses a threat to patients undergoing surgery. Medical surgical masks require a filtration efficiency of more than 95% for bacteria. For suspicious respiratory patients, disposable medical surgical masks should also be dispensed to prevent the threat of infection to other hospital personnel and reduce the risk of cross infection, but to avoid infections that are less effective than medical protective masks.
 

Performance of medical surgical masks:

1. Filtration efficiency: Under the condition of air flow (30 ± 2) L / min, the filtration efficiency for aerodynamic median diameter (0.24 ± 0.06) μm sodium chloride aerosol is not less than 30%.

2. Bacterial filtration efficiency: Under specified conditions, the filtration efficiency of Staphylococcus aureus aerosol with an average particle diameter of (3 ± 0.3) μm is not less than 95%; the filtration rate of bacteria should be ≥95%; The filtration rate should be ≥30%.

3. Breathing resistance: In the condition of filtering efficiency and flow rate, the inhalation resistance does not exceed 49Pa, and the exhalation resistance does not exceed 29.4Pa. When the pressure difference △ P for gas exchange on both sides of the mask is 49Pa / cm, the gas flow rate should be ≥264mm / s.

4. Nose clip and mask strap: The nose clip should be equipped with a nose clip made of a plastic material, and the length of the nose clip should be greater than 8.0cm. Mask strips should be easy to wear, and the breaking strength at the connection point between each mask strip and the mask body should be greater than 10N.

5. Synthetic blood penetration: After 2ml of synthetic blood is sprayed on the outer side of the mask at a pressure of 16.0kPa (120mmHg), the inner side of the mask should not penetrate.

6. Flame retardant performance: The mask material should be made of non-flammable material, and the mask will burn for less than 5s after leaving the flame.

7. Residual ethylene oxide: Ethylene oxide sterilized masks should have less than 10 μg / g of ethylene oxide.

8. Skin irritation: The primary irritation index of the mask material should be ≤0.4, and there should be no allergic reaction.

9. Microbiological indicators: The total number of bacterial colonies is ≤20CFU / g. Coliform bacteria, Pseudomonas aeruginosa, Staphylococcus aureus, hemolytic streptococcus and fungi shall not be detected.
