Medical masks synthetic blood penetration tester is used to determine the resistance of medical protective masks to penetration by synthetic blood at different test pressures,and can also be used to determine the resistance to blood penetration of other coating materials.
Application:
Mask synthetic blood penetration testeris used for anti-synthetic blood penetration of medical surgical masks, and mainly used in the field of medical protection products. It can also be used for other textile coating material determination.
Blood penetration resistance testerStandards:
GB 19083-2010Technical requirements of medical face masks - Anti-penetration property of 5.5 synthetic blood.
YY/T 0691-2008Clothing for protection against infectious agents-Medical face masks - Test method for resistance against penetration by synthetic blood (fixed volume, horizontally projected)
YY 0469-2011Technical requirements of medical face masks– Blood penetration test apparatus.
ISO 22609：2004Clothing for protection against infectious agents - Medical face masks - Test method for resistance against penetration by synthetic blood (fixed volume, horizontally projected)
ASTM F1862-07Standard Test Method for Resistance of Medical Face Masks to Penetration by Synthetic Blood (Horizontal Projection of Fixed Volume at a Know Velocity)
parameter：
| Items | Parameters |
| Injection distance | 300mm～305mm, adjustable |
| Nozzle diameter | 0.84mm |
| Jet velocity | 450cm/s,550cm/s,635cm/s |
1.The protruding sample fixture can simulate the actual use condition of the mask. Reserve the test target area without destroying the sample, and distribute synthetic blood in the sample target area.
2.A special jet device with constant pressure can spray a certain volume of synthetic blood in a controlled time.
3.It can fully simulate the corresponding injection rate to test under the average blood pressure of the human body at 10.6kPa, 16kPa, 21.3kPa.
4.The fixed target plate can block the high pressure part of the injected liquid flow to allow the steady flow to be sprayed to the sample, increasing the accuracy and repeatability of liquid spraying speed.
