The main function of the needle patency tester is to test the flow rate of the needle, under a specific pressure, the flow flow through the needle represents its unobstructed performance, and the test results are compared with the theoretical flow rate, and its patency can be determined. This product is easy to operate, the pressure control is stable, and the equipment adopts a special structure to make the outlet pressure consistent with the set pressure, so that the test results are more accurate. The needle tube patency tester is suitable for detecting conventional rigid stainless steel needles, anesthesia needles, puncture needles, medical catheters and other medical devices for injection needles, and is widely used in medical device product manufacturers, quality inspection institutes, third-party testing institutions, colleges and universities, scientific research institutes and other units. 【Relevant Standards】

“GB18671-2009 Disposable Intravenous Infusion Needle”; GB 15811-2016 Disposable sterile injection needles; “YY/T 0321.2-2021 Disposable anesthesia needles”, etc.;
