Drick Instruments Co., Ltd. implements GB 19083-2010 Technical Requirements for Medical Protective Masks, 5.5 Synthetic Blood Penetration Barrier Performance YY/T 0691-2008 Infectious Pathogen Protective Equipment Medical Masks Anti-Synthetic Blood Penetration Test Method (fixed volume, horizontal injection ) YY 0469-2011 Technical Requirements for Medical Surgical Masks Blood Penetration Test Device ISO 22609:2004 Infectious Pathogen Protective Equipment Medical Face Masks Test Method for Penetration of Synthetic Blood (Fixed Volume, Horizontal Jet) ASTM F1862-07 Standard Test Method for Resistance The DRK227 mask synthetic blood penetration tester developed and produced by standards such as Medical Face Masks to Penetration by Synthetic Blood (Horizontal Projection of Fixed Volume at a Know Velocity) is used to determine the resistance of medical masks, disposable masks and other protective masks to synthetic blood spray Splash penetration performance evaluates the resistance of masks to synthetic blood penetration, also known as mask synthetic blood penetration tester, medical mask synthetic blood penetration tester, medical surgical mask synthetic blood penetration tester, etc. DRK227 Medical Mask Synthetic Blood Penetration Tester is specially designed with constant pressure spray device, which can spray a certain volume of synthetic blood within a controlled time.
The operation method of the mask synthetic blood penetration tester is as follows:
1. Fix the sample on the sample clip. If the mask has wrinkles, unfold the wrinkles and fix it on the sample clip to ensure that the target area is a single-layer material, and the center of the sample is used as the test target area. Close the specimen clamp.
2. Press the “Start” button. At this time, a certain amount of synthetic blood is sprayed horizontally to the mask to be tested behind the positioning target. The spraying starts, and the time relay starts timing. After the set spraying time, the instrument automatically stops spraying. .
3. Press the “Stop” button to open the sample holder. Under suitable lighting conditions, inspect the viewing surface of the specimen for the presence of synthetic blood.
4. One test is over. If you need to continue the test, repeat steps 1-3 until all tests are done.
5. After the test is over, remove the synthetic blood residue in the test solution tank, replace it with distilled water, and clean the entire pipeline. After the nozzle sprays clean water, continue to drain all the clean water in the test solution tank. Close the outlet valve on the air compressor and turn off the power switch. Scrub the residual liquid pan, clean the work surface, and remove the distilled water in the test solution box.
