Scope of application: Used to determine the resistance of medical protective masks to synthetic blood penetration under different test pressures, and can also be used to determine the blood penetration resistance of other coating materials.
Instrument characteristics:
1, color touch display, friendly man-machine interface, easier to operate.
2, the spray area is equipped with a specially designed integrated sink and discharge system, which can avoid polluting other working areas and facilitate cleaning work.
3, the special sample fixing device can simulate the actual use of the mask, leaving a test area.
4, the special constant pressure injection device can spray a certain volume of synthetic blood within a specified time.
5, can simulate the average blood pressure of the human body 10.6kPa, 16kPa, 21.3kPa and other different pressure corresponding to the spray speed to carry out the test.
6, with a fixed target plate, can block the high-pressure part of the spray liquid flow, only let the steady flow part of the spray to the sample, increasing the accuracy and repeatability of the spray liquid speed to the sample.
7, the spray device is equipped with a height fine-tuning mechanism, adjustment is more convenient.
