I. Introduction
With the continuous advancement of medical technology, the performance requirements of syringes, as common medical tools, are also increasing. Among them, the sliding performance of the syringe is one of the important indicators to evaluate its quality. The Slip Performance Tester for Low Resistance Syringes is a special device designed to accurately measure the slip performance of syringes. This article will detail how the tester works, how it is tested, and what it means in practical applications.
Second, the working principle of the low-resistance syringe sliding performance tester
The low-resistance syringe sliding performance tester is mainly composed of a fixed device, a force application system, a speed control system and a data acquisition and analysis system. During the test, the body of the syringe is first fixed on the fixing device of the tester to ensure the stability of the syringe. Then, through a force application system, a constant force is applied at one end of the core rod. The speed control system ensures that the mandrel slides at a set speed. During the sliding process, the data acquisition and analysis system records and analyzes the magnitude of the test tension and test thrust in real time.
3. Test methods and procedures
Preparation: Select the syringe to be tested and make sure it meets the test requirements. At the same time, check whether the functions of the tester are normal.
Install the syringe: Attach the body of the syringe to the fixture of the tester to ensure that it is firmly fixed.
Set parameters: According to the test requirements, set the size of the force application system, sliding speed and other parameters.
Start the test: Start the tester and let the core slide at the set speed. During the sliding process, the changes in the test tension and test thrust are observed and recorded.
Data processing: After the test, the collected data is sorted and analyzed to obtain the test results.
Fourth, the significance of the sliding performance test of low-resistance syringes
The sliding performance test of low-resistance syringes is of great significance to ensure the performance and safety of syringes. Through the test, the sliding resistance of the syringe can be evaluated to determine whether it meets the requirements for use. At the same time, the test results can also provide a reference for the improvement and optimization of syringes, and promote the technological progress of the medical device industry.
V. Conclusions
The design and application of the low-resistance syringe slide performance tester provides strong technical support for the performance evaluation of syringes. Through accurate measurement and analysis, it is possible to ensure that the sliding performance of the syringe meets the requirements of clinical use, improving medical quality and safety.
