Main components and test methods of protective clothing anti-synthetic blood penetration tester

The protective clothing anti-synthetic blood penetration tester is a special equipment used to test the liquid penetration resistance of protective equipment such as surgical gowns and isolation gowns. This equipment is mainly used to evaluate whether the protective equipment can effectively prevent liquid penetration when it comes into contact with liquids such as synthetic blood, thereby protecting the safety of medical staff and patients.

It is mainly composed of a test chamber, injection system, pressure control system, data acquisition and processing system, and other parts. A sample fixture is provided in the test chamber to fix the protective clothing sample to be tested. The injection system includes nozzles, pumps, and other components, which are used to spray synthetic blood onto the protective clothing sample. The pressure control system is used to adjust the pressure of the injection system to ensure that the injected synthetic blood has a certain impact force. The data acquisition and processing system is used to record various parameters during the test and calculate the protective clothing's anti-synthetic blood penetration performance.

The working principle of the tester is: to fix the protective clothing sample on the sample fixture in the test chamber, start the injection system, and spray the synthetic blood onto the protective clothing sample at a certain pressure and speed. The protective clothing's anti-synthetic blood penetration performance is evaluated by observing whether there is synthetic blood penetration on the other side of the protective clothing sample and calculating the amount of synthetic blood that penetrates.

Test method of protective clothing anti-synthetic blood penetration tester:

1. Preparation: Cut the protective clothing sample into an appropriate size, place it on the sample fixture in the test chamber, and fix it. Check whether the injection system, pressure control system, and other equipment are working properly.

2. Injection parameter setting: Set the pressure, injection speed, and other parameters of the injection system according to the standard requirements.

3. Start the test: Start the injection system to spray synthetic blood onto the protective clothing sample. Observe whether there is synthetic blood penetration on the other side of the protective clothing sample, and record the amount of synthetic blood that penetrates.

4. Data processing: Calculate the anti-synthetic blood penetration performance of the protective clothing based on the test results.

5. Result analysis: Compare the anti-synthetic blood penetration performance of different protective clothing to provide a basis for medical staff to choose appropriate protective equipment.

Protective clothing anti-synthetic blood penetration tester is widely used in medical and health, disease prevention and control, biosafety, and other fields. By testing the anti-synthetic blood penetration performance of protective clothing, the safety performance of protective clothing in actual use can be effectively evaluated, providing effective protection for medical staff and reducing the risk of infection.
