It is used to measure the resistance of medical protective masks to the penetration of synthetic blood under different test pressures, and can also be used to determine the blood penetration resistance of other coating materials.

Instrument characteristics
1. The convex sample fixing device can simulate the actual use state of the mask, leaving the test target area without damaging the sample, and distributing the synthetic blood in the target area of the sample.
2. The specially-made constant-pressure injection device can inject a certain volume of synthetic blood within a controlled time.
3. Can fully simulate the average blood pressure of the human body 10.6kPa, 16kPa, 21.3kPa corresponding to the injection speed to conduct the test.
4. There is a fixed target plate, which can block the high-pressure part of the sprayed liquid flow, and only let the steady-state flow part be sprayed on the sample, which increases the accuracy and repeatability of the liquid velocity sprayed on the sample.
