The working principle of Synthetic blood penetration tester

Synthetic Blood Penetration Tester is a specialized device used to evaluate the impermeability of materials, particularly playing a crucial role in industries such as medical care, textiles, and protective clothing manufacturing.

I. Brief Introduction

The Synthetic Blood Penetration Tester simulates the penetration behavior of human blood using a special synthetic liquid to assess the blood resistance of materials. This tester is widely used in the medical industry to test the impermeability of medical supplies such as surgical gowns, protective clothing, and masks, ensuring that these products can effectively block the penetration of blood or other bodily fluids, thereby providing necessary protection.

II. Working Principle

The working principle of this tester is based on the penetration behavior of synthetic blood under pressure. During the testing process, synthetic blood is evenly dripped or sprayed onto the material to be tested, and then it is observed whether the liquid can penetrate the material within a certain period. If the liquid can penetrate quickly, it indicates that the material has poor impermeability; conversely, it suggests good impermeability. The tester usually has multiple settings for spray pressure and spray duration to accommodate different materials and testing requirements.

III.Standards

ASTM F903, ASTM F1670, ASTM F1671/F1671M , YY/T0700, GB19082, ISO16603, ISO 16604, IS 16545, ISO 16546

IV. Main Features

• Efficiency: The tester can complete testing of a large number of samples in a short period, improving testing efficiency.
• Stability and Repeatability: Due to the use of synthetic liquid, test results are not limited by the availability of actual blood, providing higher stability and repeatability.
• Simulation of Real-world Conditions: The tester can simulate penetration scenarios under different pressures and flow rates, providing a more comprehensive assessment of the material's impermeability.

• Ease of Operation and Maintenance: The tester's operating interface is usually simple and intuitive, easy to learn; meanwhile, the equipment is also easy to clean and maintain to ensure long-term stable operation.

V. Testing Standards and Application Scope

The testing standards for the Synthetic Blood Penetration Tester typically include international standards such as ISO, ASTM, YY/T, as well as national standards like GB. These standards stipulate requirements for the tester's testing methods, testing conditions, and test result judgments. The application scope of the tester is broad, not limited to medical supplies such as protective clothing and masks in the medical industry, but also used to evaluate the waterproof, oil-repellent, and stain-resistant properties of textiles.
