The experimental procedure of the slide tester of pen syringe piston

Pen syringe is mainly composed of pen cap, pen core, syringe and injection needle It is named after its pen shape It is mainly used for insulin injection, also known as insulin pen or injection pen Insulin is stored in the refill Before use, the injection needle is protected by a pen cap to prevent accidental puncture When using, take off the pen cap, expose the injection needle, and realize the delivery of drugs Through injection, drugs will directly enter the body or human blood, which will have a great impact on human health and life safety Therefore, the state specially formulated relevant standards to regulate and manage pen syringes Piston sliding is one of the most important indexes Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd has developed a pen syringe piston sliding tester according to the 2015 new drug packaging material standards such as ybb00152004-2015 chlorinated butyl rubber piston and gasket for pen syringe and ybb00162004-2015 Australian butyl rubber piston and gasket for pen syringe Yyb-01 is specialized in testing the piston sliding performance of pen syringe and pre filling syringe When the pen syringe piston sliding tester is used to test the pen syringe piston sliding tester, please refer to the steps specified in ybb00152004-2015 chlorinated butyl rubber piston and gasket for pen syringe: take 10 pen syringe sleeves with silicone oil treated inner surface, inject water, install the test piston and gasket, add aluminum cap and seal Install a pen syringe sleeve on the pen syringe sleeve holder (the holder must be able to puncture the gasket installed on the pen syringe sleeve, and the injection needle is a hypodermic needle with a cutting edge at one or two ends, with an outer diameter of 0.4mm, When the piston moves, the water in the sleeve shall be able to be discharged through the needle) and connected Move the piston downward at a speed of 40mm / min ± 3mm / min when moving half the distance in the pen syringe sleeve, pause for 5 seconds, and then press the piston completely to the end The other pen syringe sleeves are operated in the same way Record the Zui big force of starting piston in each test, take the average value of 10 Zui big values as "starting force", which shall not exceed 30n; record the force required to maintain its movement after starting in each test, take the average value of 10 values as "continuous driving force", which shall not exceed 15N; record the Zui big force of re pushing piston after 5 seconds pause in each test, which shall be taken as 10 Zui big forces The average value of the value is "restart force", which shall not exceed 30n; and check that there shall be no "chatter" (irregular movement of piston) during continuous movement Pen syringe piston slide tester The pen syringe piston sliding tester yyb-01 can be used with a number of test aids such as breaking force fixture, combined cover opening force fixture, stretching fixture, needle point puncture force test fixture, sliding test fixture, body tightness test fixture, thermal strength test fixture to complete a variety of packaging materials such as medical aluminum foil, PVC hard film, composite film bag, combined cover, ampoule bottle, medical rubber plug, etc Rational detection is a necessary instrument for research institutions, packaging manufacturers, pharmaceutical enterprises, inspection and quarantine institutions As a convenient and simple injection technology, pen syringe will get more and more attention and use of diabetic patients, which will promote the rapid development of pen syringe Manufacturers of relevant products should pay close attention to relevant standards, improve product quality and promote industry development For more information about the pen syringe piston slide tester, please call Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd.
