Retention Needle Rigidity Tester - Overview

Retention needle rigidity testerThe model is GXY-02, developed and produced by Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd. It is suitable for measuring the deflection value of injection needles and other medical devices using hard straight stainless steel needles for intradermal, subcutaneous, muscular, and venous injection in the human body. Complies with the requirements of GB 18457-2015 "Stainless Steel Needle Tubes for Manufacturing Medical Devices", YBB00092004-2015 "Stainless Steel Injection Needles for Pre filled Syringes", and GB 15811-2001 "Sterile Injection Needles for Disposable Use". So why is it necessary to test the rigidity of medical injection needles, and what are the testing methods? Below, technicians from Jinan Sanquan Zhongshi will give you a brief introduction:

Stainless steel needle tubes for medical devices such as disposable sterile injection needles, disposable intravenous infusion needles, disposable anesthesia needles, and disposable venous blood collection needles all have requirements for needle tube rigidity. In actual measurement, due to different settings, the measurement results may vary, resulting in measurement deviation. So it is necessary to use a medical injection needle tube rigidity tester to test the rigidity of various needles.

GXY-02Retention needle rigidity testerIt has the permission setting function specified in the 2015 drug packaging material standard, and the instrument can be operated by both touch screen and button operation, which has epoch-making significance. The GXY-02 new generation medical injection needle tube rigidity tester contains a force sensor of 200N and a displacement sensor, with an accuracy of 0.001mm. Through multiple tests, the instrument can print the maximum value, minimum value, and average value. The testing principle is to apply a specified force to the center of the specified span of the needle tube supported at both ends, and measure the deflection value of the needle tube.
