Ybb00092004 test method of needle point puncture force tester for pre filling injection needle

Pre potting injection needle, including needle head, needle seat, infusion tube and protective sleeve, is a basic clinical nursing operation equipment With the wide use of pre potting injection needle in clinical, its quality is directly related to human health and life safety Whether the puncture force of the needle tip of the pre filling injection needle is suitable or not directly affects its use adaptability, which is one of the key indicators of the manufacturers Ybb00322004-2015 test method for puncture force of medical rubber plug clearly stipulates that: the puncture force test method of infusion needle tip is to use a puncture force test device to make the injection needle pass the Zui peak force measured when simulating the skin vertically at the specified speed to evaluate the puncture force of the injection needle The national standard ybb00092004-2015 specifies the puncture force of the injection needle Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd has developed ccy-02 pre filling needle tip puncture force tester in accordance with the requirements of the standard, It is also known as needle point puncture force tester, medical needle point puncture force tester, etc the instrument is equipped with professional sensors, full-automatic operating system, micro printer, professional humanized fixture, which can complete the experiment quickly and accurately The needle point puncture force tester is used to detect the needle point puncture force of the pre filling injection needle The detection methods are as follows: 1 Place the tested needle and the simulated skin at 22 ℃± 2 ℃ for at least 24 hours, and test at the same temperature; 2 Clamp the appropriate size of simulated skin C on the fixture of the measuring device, without any obvious stretching or shrinking force applied on the simulated skin 3 Install the tested needle on the device B, its axis is perpendicular to the surface of the simulated skin C, and the needle tip points to the center of the circular puncture area 4 Set the moving speed to 100 mm / min, 5 Start the test device 6 During the process of puncture on the membrane, measure the peak force or record the force / displacement diagram at the same time Note: do not use the membrane that has been punctured in the circular puncture area Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd has advanced testing technology, packaging testing equipment and professional laboratory, and is committed to providing customers with comprehensive packaging quality control solutions
