During the test, a certain amount of synthetic blood was sprayed horizontally to one side of the mask at a certain pressure and distance, and the penetration of synthetic blood on the other side of the mask was observed.

The device is used for the anti-synthetic blood penetration ability of medical surgical masks, mainly used in the field of medical protective products, and can also be used for the determination of other textile coating materials.

Its application fields include but are not limited to:

Manufacturer of medical masks;

 Metrology verification department;

Research institutes;

Commodity inspection or quality control department of the manufacturer;

 Third-party testing platform;

Quality supervision and market supervision and inspection units in various places;

GB 19083-2010 Medical protective mask technical requirements, 5.5 synthetic blood penetration barrier performance

YY / T 0691-2008 protective equipment for infectious pathogens, medical masks, synthetic blood penetration resistance test method (fixed volume, horizontal injection)

YY 0469-2011 Technical requirements for medical surgical masks Blood penetration test device

ISO 22609: 2004 protective equipment for infectious pathogens, medical masks, test method for penetration of synthetic blood (fixed volume, horizontal injection)

l lThe mask fixture is a metal human head model, which can fully simulate the actual use state of the mask.

l lThe metal human head mold can rotate at a certain angle, which is convenient for sample clamping.

l l Special spray control device can spray a certain volume of synthetic blood within the controlled time.

l l The instrument adopts an air source that can provide (700 ± 25) kPa stable air pressure, which is not affected by the space of the test site.

l lIt can simulate the liquid ejection speed corresponding to human blood pressure 10.6kPa, 16.0 kPa, 21.3 kPa (namely 80mmHg, 120mmHg, 160mmHg) for testing.

l l There is a fixed target plate, which can block the high-pressure part of the sprayed liquid flow, and only let the steady-state flow part be sprayed on the area sample, which increases the accuracy and repeatability of the test.

l lThe instrument adopts imported special aluminum brushed panel with metal buttons, which is sensitive to operation and not easy to damage.

l lThe 7-inch color touch screen displays the test parameters, and the menu-type operation mode is as convenient as a smartphone.

l lThe core control components adopt STMicroelectronics 32-bit multi-function motherboard.

l lThe instrument code adopts 304 stainless steel, which is durable, neat and clean in appearance. ;
