The device is used for anti-synthetic blood penetration of medical surgical masks, and mainly used in the field of medical protection products. It can also be used for other textile coating material determination.

1. The convex sample fixing device can simulate the actual state of use of a mask, leave a test target area without damaging the sample, and distribute the synthetic blood in the target area of the sample.

2. The special constant pressure spray device can spray a certain volume of synthetic blood in a controlled time. 3. It can fully simulate the human body's average blood pressure of 10.6kPa, 16kPa, and 21.3kPa spray speeds for testing.

3. Equipped with a target plate, which can block the high-pressure edge portion of the sprayed liquid flow, and only let the steady-state flow portion be sprayed on the sample, which increases the accuracy and repeatability of the liquid velocity sprayed on the sample.

4. Color touch screen operation.

5. Equip with thermal printer for printing results.
