In this battle against the pneumonia caused by the novel coronavirus infection in Wuhan, the Hubei Provincial Institute of Apparatus was responsible for the emergency call of the Provincial New Coronavirus Pneumonia Prevention and Control Headquarters and the New Coronavirus Pneumonia Prevention and Control Leading Group of the Hubei Provincial Drug Administration. The benchmarking evaluation, inspection and testing of controlled products (medical masks, protective clothing and other medical emergency products that have not been registered in China). At 10 pm on January 27, the Hubei Provincial Institute of Medical Device Supervision and Inspection received 6 batches of medical protective clothing inspection tasks. The technicians worked day and night to complete all inspection tasks within 24 hours, half a working day earlier than expected.

The instrument used to test the synthetic blood penetration performance of medical protective clothing isLFY-228 Medical Protective Clothing Synthetic Blood Penetration Performance Tester developed by Shandong Textile Science Research Institute.

LFY-228 Synthetic Blood Penetration Tester for Medical Protective Clothing

The main purpose
It is suitable for testing the resistance of protective clothing to penetration of synthetic blood under different levels of test pressure.
Working principle
The protective clothing material is tested with synthetic blood under continuous pressure, and the penetration of synthetic blood on the material is visually inspected.
Instrument characteristics
1. The instrument uses an air source that can provide (20 ± 1) kPa air pressure to continuously pressurize the sample without being restricted by the space of the test site.
2. The instrument has a pressure gauge to display the pressure, which is adjustable.
3. Use pressurized medium: compressed air.
4. The special stainless steel penetrating test tank guarantees a firm grip on the sample and prevents synthetic blood from splashing around.
5. Square metal blocking net: open space ≥50%; bending ≤5mm under 14kPa.
6. Digital display timer, accuracy ±0.01min.
7. The instrument has a clamp that can produce 13.5N·m torque.
8. The structure of the instrument is the same as the "Schematic diagram of the test instrument" and "The structure of the test tank" in the GB19082-2009 standard.
Technical index
1. Pressure point: 1.75kPa 3.5kPa 7kPa 14kPa 20kPa
2. Sample size: 75mm×75mm
3. Power supply: AC220V, 50Hz, 100W
Applicable standards
