Author:QINSUN Released in:2023-08 Click:103

Medical Mask Synthetic Blood Penetration Tester is used to test the resistance of medical protective masks to synthetic blood penetration under different experimental pressures, and can also be used to test the resistance to synthetic blood penetration of medical masks. other coating materials. It is a test equipment independently developed and produced by Qisnun Precision Electromechanical Technology Co., Ltd.

Conforms to standard:

GB/T 32610, YY0469, ASTM F1862-07

Main parameters:

1. Spraying distance: 300-305mm adjustable;

2. Nozzle size: 0.84mm;

3. Spray rate: 450cm/s, 550cm/s, 635cm/s;

4. The nozzle length: 12.7mm;

5. The target plate aperture: 0.5cm.

Test principle:

The medical mask sample is supported on the test device and 2 ml of bloodare placed at a distance of 300 mm Spray horizontally from a housing with an internal diameter of 0.84 mm towards the mask to be tested. Simulate the scene where the mask is sprayed with blood from the punctured blood vessel, and observe the penetration of synthetic blood on the other side of the mask.

The medical mask samples were tested at the liquid injection pressure corresponding to the liquid injection speed: 450 cm/s, 550 cm/s and 635 cm/s. Record the test results of each jet speed and give the blood pressure corresponding to the acceptable quality level limit of the medical mask being 4.
