The synthetic blood is squirted on the mask sample at a pressure of 10.7kPa (80mmHg), and shouldn’t penetrate the interior of the mask.

Medical-Surgical Masks

These masks are suitable for basic protection of medical personnel, as well as protection against blood, body fluids, and splashes during invasive operation. The protection level is average, and it has some confirmed respiratory protection performance. It is generally worn in a clean environment of less than 100,000, operating in the operating room, nursing patients with low immune function, and performing body cavity puncture. This type of masks can wedge 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 masks require a filtration efficiency of more than 95% for bacteria. For suspicious respiratory patients, disposable medical surgical masks should also be distributed to prevent other hospital personnel from posing a threat of infection and reduce the risk of cross-infection.

Important technical indicators include filtration efficiency, bacterial filtration efficiency, and respiratory resistance. The specific indicators are as follows:

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