Manual Control Method Synthetic Blood Penetration Tester For Medical Masks

Product overview:

The synthetic blood penetration tester for medical masks is used to measure the jet penetration performance of synthetic blood and other liquid sources in order to evaluate the safety performance of masks. It is mainly used to test the permeability of mask to blood, body fluid, blood causative agent (using Phi-X174), synthetic blood, etc. Suitable for liquid penetration resistance of protective equipment such as masks, gloves, protective clothing, overalls, work clothes, boots, etc. The equipment can output test reports and save test data.

Test method:

The sample of medical mask was supported on the test device, and 2 mL synthetic blood with a surface tension of 0.042 ± 0.002 n / m was sprayed from 300 mm away from the mask under test at a pressure of 16 kPa in the horizontal direction by a catheter with an inner diameter of 0.84 mm. To simulate the mask being splattered with blood from a perforated vessel. Remove the mask within 10 seconds and visually inspect the artificial blood infiltration on the other side of the mask. Respectively with the corresponding liquid injection pressure of 450 cm / s, 550 cm / s, 635 cm / s The medical masks were tested, the test results of each jet velocity were recorded, and the maximum blood pressure corresponding to the quality qualification level limit 4 of the medical masks was given.
