Syringe Fit Positive Pressure Tester: A key tool for ensuring the safety and reliability of syringes.
With the advancement of medical technology and the wide application of syringes in the medical field, the syringe fit positive pressure tester has become a key tool to ensure the safety and reliability of syringes. This article will introduce the test principle, test process, test standard and equipment selection in detail, aiming to help readers understand the importance of the syringe fit positive pressure tester, and guide users to test correctly and scientifically.
First, the test principle.
The Syringe Fit Positive Pressure Tester uses the positive pressure method to evaluate the sealing performance of a syringe. During the test, the syringe is connected to the test instrument, and a certain positive pressure is formed inside the syringe by pressurization, and then the pressure change is observed to evaluate the sealing performance of the syringe. This method can effectively detect the leakage of syringes and ensure that there will be no leakage of liquid medicine during the use of syringes, resulting in potential safety hazards such as cross-infection.
Second, the test process.
1.Preparation: Prepare the syringes, test instruments and required auxiliary tools to be tested;
2.Install the syringe: connect the syringe to the test instrument and adjust the position;
3.Pressurization test: set the corresponding pressure value according to the test requirements, and start the test instrument for pressurization test;
4.Observation results: The sealing performance of the syringe is judged by monitoring the pressure change displayed by the test instrument;
5.Record data: record the test results, including important information such as syringe model, test date, test pressure value, etc.;
6.Analysis and evaluation: According to the test results, analyze and evaluate to determine whether the syringe meets the requirements.
3. Test standards.
Different regions and different medical institutions may have different testing standards, but in general, the following indicators are important bases for syringe fit positive pressure testing:
1.Pressure holding time: Under a certain test pressure, the syringe should be able to hold for a certain period of time without significant pressure drop;
2.Rate of pressure change: In a certain period of time, the rate of pressure change of the syringe should be within a certain range and cannot exceed the set threshold;
3.Leak detection: The syringe cannot leak any liquid medicine during the test, and there are strict requirements for sealing performance;
4.Repeatability testing: Syringes from the same batch should be tested multiple times to ensure reliable and consistent test results.
