Medical Mask Synthetic Blood Penetration Tester Ejection Rate

Author:QINSUN Released in:2023-10 Click:112

The synthetic blood penetration tester for medical masks is used to measure the resistance of medical protective masks to the penetration of synthetic blood under different experimental pressures. It can also be used to measure the blood penetration resistance of other coating materials. This is a qisnun precision testing equipment independently developed and produced by Mechanical and Electrical Technology Co., Ltd.

Complies with standards:

GB/T 32610, YY0469, ASTM F1862-07

Main parameters:

1. Distance from spray: 300-305 mm adjustable;

2. Nozzle size: 0.84mm;

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

4.Nozzle length: 12.7mm;

5. Fixed target plate opening: 0.5cm.

Test principle:

The sample of the medical mask is supported on the test device, And2 mL of synthetic blood are placed at a distance of 300 mm. Spray from a housing with an inner diameter of 0.84 mm onto the mask under test in an actual direction. Simulate the scene where the mask is splattered with blood from a punctured blood vessel and watch as the synthetic blood penetrates the other side of the mask.

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