Anti-synthetic blood penetration tester

Anti-synthetic blood penetration tester

The synthetic blood penetration tester for medical masks is used to measure the jet penetration performance of synthetic blood and other liquid-derived liquids to evaluate its safety protection performance.

Applicable standards

GB19083-2010: Technical requirements for medical protective masks;

YY 0469-2011: medical surgical masks;

The main purpose

It is suitable for the determination of the anti-splatter penetration performance of synthetic blood of medical masks. It can be used by medical inspection department, safety inspection department and scientific research unit.

Principle

The medical mask sample is supported on the test device, and at a distance of 300mm, 2mL of synthetic blood is sprayed from a sleeve with an inner diameter of 0.84mm to the mask under test in a horizontal direction. Simulate the scene where the mask is splashed with blood from the perforated blood vessel, and observe the penetration of synthetic blood on the other side of the mask.

The medical mask samples were tested with the liquid ejection pressure corresponding to the liquid ejection velocity: 450 cm/s, 550 cm/s, and 635 cm/s. Record the test results of each jet velocity, and give the maximum blood pressure corresponding to the acceptable quality level limit of 4 for medical masks.
