Medical needle tube toughness tester principle

　　The medical needle toughness tester is a professional testing instrument for detecting disposable medical consumables, mainly used to test the toughness performance of medical needles. Common medical needles include injection needles, blood collection needles, acupuncture and moxibustion needles, retention needles, collection needles, microwave ablation needles, puncture needles, biopsy needles, etc.

　　Working principle:

　　Fix one end of the needle firmly on the fixture, adjust the specified span load corresponding to the tested needle according to the standard regulations, and select the following bending angles: normal wall 25 °, thin-walled 20 °, and ultra-thin wall 15 °. Apply a sufficiently large force at the specified span position, at a frequency of 0.5Hz, 20 times in both directions, and observe the breakage of the needle tube visually.

　　Technical advantages:

　　1. Precision

　　We use high-precision and high-density sensors to accurately measure the changes and load conditions of the test needle during the force process, so the accuracy of the test data provided after the test is very high. Effective and high-precision testing data can provide strong data support for medical needle (needle) production enterprises in evaluating product quality.

　　2. [Easy to operate]

　　We use a user-friendly human-machine dialogue interface, and the operation can be completed according to the instructions on the interface. In addition, manufacturers of medical needle (needle) toughness testers generally provide operation training services to help staff quickly get started.

　　3. 【 Listen to the sound to know the result 】

　　Equipped with a built-in buzzer, if the detection result is unqualified, the buzzer will be activated, and an alarm will remind the staff to pay attention to the unqualified toughness performance of the medical needle being tested.
