The Needle Toughness Tester is an instrument specially used to test the toughness performance of medical needle tubes. The toughness of medical syringes is one of its important physical properties, which is directly related to the safety and effectiveness of syringes during use. Therefore, the needle tube toughness tester has a wide range of applications in the medical device industry.
The main working principle of the tester is to simulate the bending situation in the actual use process, apply a certain force to the needle tube to bend and deform, and then measure the degree of deformation of the needle tube and whether it is broken to evaluate its toughness. Instruments are usually composed of fixtures, sensors, control systems, and data processing systems, which can realize automated testing and data logging.
Applications for the Needle Toughness Tester include:
Quality control: In the production process of medical syringes, by using the syringe toughness tester for testing, the toughness of the syringe that does not meet the requirements can be found in time, so as to ensure the overall quality of the product.
Product R&D: The needle toughness tester can be used to evaluate the toughness performance of different materials and different designs, provide data support for product development, and help select the optimal design scheme.
Standards Development and Conformance Testing: The Syringe Toughness Tester can also be used to develop relevant standards for medical syringe toughness testing, and to perform compliance testing on medical syringes on the market to ensure that they meet the requirements of relevant regulations and standards.
In short, the needle toughness tester is an indispensable testing equipment in the medical device industry, and its use can improve the quality and safety of medical needles and ensure the safety of patients. During use, it is necessary to test in strict accordance with the operating procedures, and regularly maintain and calibrate the instrument to ensure the accuracy and reliability of the test results.
The measurement principle of the needle tube toughness tester is to evaluate the toughness of the needle tube by simulating the bending situation during actual use, applying a certain force to the needle tube to bend and deform, and then measuring the degree of deformation of the needle tube and whether it is broken. Specifically, during the test, the needle tube is fixed to the fixture of the test instrument, and then a gradually increasing bending force is applied to bend and deform the needle. During the application of force, the sensor monitors the deformation of the needle barrel in real time and records it. When a certain amount of force is applied, the needle tube may break. At this point, the instrument records the maximum bending force and deformation in the event of a fracture of the needle. Based on these test data, the toughness performance of the needle can be evaluated.
The measuring principle of the needle tube toughness tester is based on the relevant theories of material mechanics and elastic mechanics. During the application of force, the syringe undergoes elastic and plastic deformation. Elastic deformation refers to the deformation of a material after being subjected to force, but when the external force is removed, it can completely return to its original shape and size. Plastic deformation refers to the deformation of the material after being subjected to force, and even if the external force is removed, it cannot completely return to its original shape and size. The toughness of a syringe depends on its ability to resist plastic deformation and breakage.
The measurement results of the needle tube toughness tester usually include the maximum bending force, the maximum amount of deformation, the bending force at break, and other indicators. These indicators can reflect the toughness performance of the syringe and provide an important basis for the quality control, product development and production process monitoring of medical syringes. At the same time, the needle tube toughness tester also has the advantages of automation, high precision and high reliability, which can greatly improve the testing efficiency and accuracy.
