YY / T0691-2008 Medical Mask Synthetic Blood Penetration Tester
Overview:
The mask synthetic blood penetration tester is suitable for the measurement of the spatter penetration performance of medical mask synthetic blood. It can be used by medical inspection departments, safety inspection departments and scientific research units.
Principle
The medical mask sample was supported on the test device, and 2 mL of synthetic blood was sprayed from a cannula with an inner diameter of 0.84 mm in a horizontal direction toward the mask to be tested at a distance of 300 mm. Simulate the scene where the mask is sprayed with blood from the perforated blood vessels, and observe the penetration of synthetic blood on the other side of the mask. The medical mask samples were tested at the liquid ejection speeds of 450 cm / s, 550 cm / s, and 635 cm / s, respectively. Record the test results for each injection speed.
