The pen-type syringe is mainly composed of a cap, a refill, a syringe and an injection needle. It is named for its shape and is mainly used for insulin injection, also known as an insulin pen or an injection pen. Insulin is stored in the refill, and the needle is protected by a cap before use to prevent accidental puncture. When in use, the cap is removed to expose the needle for drug delivery. Through injection, the drug will directly enter the body or human blood, which will have a great impact on human health and life safety. Therefore, the state has specially formulated relevant standards to regulate and manage pen-type syringes. Piston sliding is one of the important indicators.
Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd. refers to YBB00152004-2015 "chlorinated butyl rubber piston and gasket for pen injector" and YBB00162004-2015 "Australian butyl rubber piston and gasket for pen injector" and other new 2015 drugs The standard for the packaging material has developed a pen-type syringe piston slidability tester YYB-01, which is specially used to detect the piston sliding performance index of pen-type syringes and pre-filled syringes.
Pen syringe piston sliding tester
When testing with the pen injector piston slidability tester, refer to the steps specified in YBB00152004-2015 "Chlorobutyl rubber pistons and gaskets for pen injectors":
Take 10 pen-type syringe sleeves treated with silicone oil on the inner surface, fill with water, install the test piston and gasket, add aluminum cap, and seal. Install a pen-type syringe sleeve on the pen-type syringe sleeve holder (with flat and piston contact, the holder must ensure that the spacer is mounted on the pen-type syringe sleeve, the injection needle is one end The hypodermic needle with a cutting edge has an outer diameter of 0.4 mm. When the piston moves, the water in the sleeve should be able to be connected through the needle. The piston is moved downward at a speed of 40 mm/min ± 3 mm/min, in a pen injector. When moving halfway through the sleeve, pause for 5 seconds, then fully press the piston to the end, and the remaining pen syringe sleeves operate the same way. Record the large force of the Zui starting piston in each test, take the average value of 10 large values ​​of Zui as the "starting force", should not exceed 30N; record the force required to keep the movement after starting in each test, take 10 The average value of the values ​​shall be “15% continuousâ€; the maximum force of the piston shall be re-pushed after 5 seconds of pause in each test, and the average value of 10 large values ​​of Zui shall be taken as “restarting forceâ€. ", should not pass 30N; and check that there must be no "vibration" during the continuous movement (referring to the irregular movement of the piston).
Pen syringe piston sliding tester
Pen Syringe Piston Sliding Tester YYB-01 can be used with breaking force clamp, combined cover opening force clamp, tensile clamp, needle tip penetration test fixture, slidability test fixture, body tightness test fixture, heat sealing strength test fixture And a number of test aids complete the physical properties testing of medicinal aluminum foil, PVC hard film, composite film bag, combination cover, ampoule, medicinal rubber plug and other packaging materials, is a research institution, packaging material manufacturer, pharmaceutical company , necessary equipment for inspection and quarantine institutions.
As a convenient and simple injection technique, pen syringes will gain more and more attention and use from diabetic patients, which will promote the rapid development of pen injectors. Manufacturers of related products should pay close attention to relevant standards, improve product quality, and promote industry development.
