Medical Face Fabric Textile Garment Protection Clothing Synthetic Blood Penetrability Tester

Medical Face Fabric Textile Garment Protection Clothing Synthetic Blood Penetrability Tester
Application:
Synthetic blood penetration tester is developed for ranking the synthetic blood penetration resistance performance of medical face masks in a manner representing actual use as might occur when the face mask is contacted by a high velocity stream of blood from the punctured wound.
Synthetic Blood Penetration Tester is used for the determination of resistance of penetration by the synthetic blood under the different levels of test pressure to medical protective clothing.
A specimen medical face mask is supported on an apparatus. A fixed volume of synthetic blood is sprayed horizontally at the specimen mask to simulate the scenario of a mask being splashed by a punctured blood vessel. The volume of fluid, distance to impact, orifice size and fluid velocity are defined in their methods and intended to be consistent with this health care scenario.
Standard:
GB 19082-2003Medical disposable protective clothing technology requires synthetic blood penetration test method;
ASTM F1670 / F1670M - 17a Standard Test Method for Resistance of Materials Used in Protective Clothing to Penetration by Synthetic Blood
Features:
1. Provides 0.5 ~ 30 +/- 0.1 kPa air pressure to the specimen
2. Air pressure can be set freely, set range 0.5 ~ 30 kPa
3. Color touch-screen display, user-friendly operation.
4. Equipped with the automatic specimen clamping
5. Test head is made of high-quality 316 stainless steel, a high strength cover
6. Square metal block network: more than 50% open space; less than 5mm bending under 30kPa.
Sample preparation:
In the sample of each protective suit, 3 pieces (75*75) mm are randomly selected. When conducting the experiment on the composite or multi-layer materials, the edges should be sealed and the diameter shoud be kepted greater than 57mm for testing.
Instrument characteristics:
1. The instrument adopts the air source which can provide (0.5---30 + 0.1)kPa pressure to continuously pressurize the sample, and is not subject to the space limitation of the test site;
2. The range of air pressure can be set freely and set range (0.5---30)kPa;
3. Color touch screen display, Chinese and English operation menu, user can freely choose the language operation;
4. The sample surface is made of imported special aluminum profiles, with light material, smooth surface and never rust;
5. The instrument adopts imported special aluminum drawing panel with metal buttons;
6. The instrument is equipped with a sample automatic clamping device without manual clamping;
7. The test tank is equipped with special fixed device to facilitate customer operation;
8. The test tank is made of high quality 316 stainless steel, with high transparent and high intensity protective cover.
9. Square metal block: open space is more than 50%; Under 30kPa, the bending is less than 5mm;
10. The precision of instrument time control is less than 0. 1 second;
11. High quality metal baking paint is used for the whole machine shell.
