A needle tube rigidity tester is a professional equipment used to test the rigidity of needle tubes (such as syringes, infusion sets, etc.). In medical, pharmaceutical and other fields, the rigidity of the needle is crucial for its performance and safety. The Needle Rigidity Tester ensures the quality and reliability of the needle through a series of precise tests to ensure the safety and effectiveness of medical operations.
1. The working principle of the needle tube rigidity tester.
The needle tube rigidity tester usually uses the principle of mechanics to detect the bending, deformation or fracture of the needle tube by applying a certain force or pressure. During the test, the needle stiffness tester will simulate various conditions in actual use, such as temperature, humidity, pressure, etc., to more accurately reflect the real performance of the needle.
Second, the main components of the needle tube rigidity tester.
1.Main unit: The main unit is the core part of the needle tube rigidity tester, which is usually composed of high-precision sensors, controllers and actuators. The sensor is used to detect the deformation of the needle tube after being forced, the controller is responsible for controlling the various parts of the testing process, and the actuator is responsible for applying force and pressure.
2.Test fixture: The test fixture is a device used to fix and position the needle tube, which can be replaced or adjusted according to different specifications of the needle tube. The design of the fixture should fully consider factors such as the size, shape and material of the needle to ensure the accuracy and reliability of the test results.
3.Control system: The control system is an important part of the needle tube rigidity tester, which is responsible for controlling the test process and data collection and processing. The control system is usually implemented using computer technology, which can complete the test process automatically and display or record the test data in real time.
4.Software system: The software system is the "brain" of the needle tube rigidity tester, which is responsible for controlling the testing process, data processing, result analysis, etc. Software systems are usually written in professional programming languages, with user-friendly interfaces and powerful data processing capabilities.
3. Test method of needle tube rigidity tester.
1.Prepare the sample: Select a certain number of samples of the stylus tube to be tested and ensure that the sample has no obvious cosmetic defects or damage.
2.Mounting the fixture: Install the needle tube sample into the test fixture to ensure that the fixture is in good contact with the sample and there is no loosening.
3.Set test parameters: Set appropriate test parameters, such as force, deformation, test speed, etc., according to relevant standards and requirements.
4.Start Test: Start the instrument and start the test. During the test, the instrument applies a certain force or pressure to the needle tube sample and monitors its deformation in real time.
5.Result analysis: According to the test data, the stiffness performance of the needle tube is analyzed. Parameters such as deformation and bending angle are usually calculated and compared to standard values to determine whether the needle is qualified or not.
6.Generate reports: Generate detailed test reports based on test and analysis results. The report should include test data, results analysis, and conclusions to evaluate the quality and reliability of the syringe.
Fourth, the application value of the needle tube rigidity tester.
1.Ensure medical safety: By testing the rigidity of the needle, unqualified products can be found in time to avoid medical accidents and potential safety hazards caused by substandard quality of the needle.
2.Improve pharmaceutical efficiency: Rigid and qualified needles can ensure the smooth operation of injections and infusions, thereby improving pharmaceutical efficiency.
3.Reduce costs: Timely detection of unqualified syringes can prevent them from entering the production and use process, and reduce the cost loss caused by quality problems.
