Scope of Application

【Operating Instructions】

【Scope of Application】The main function of the catheter flow rate tester is to measure the flow rate through a needle or catheter. Under a specific pressure, the flow rate through the catheter represents its patency performance. By comparing the test result with the theoretical flow rate, it can be determined whether the flow velocity is acceptable. This product is easy to operate, features automatic water filling, stable pressure control, and a special structure that keeps the outlet pressure consistent with the set pressure, ensuring more accurate test results。The catheter flow rate tester is suitable for testing conventional intravascular catheters, non-vascular catheters, disposable sterile urinary catheters, disposable infusion sets, peritoneal dialysis catheters, and various other medical catheters. It is widely used by medical device manufacturers, quality inspection institutes, third-party testing organizations, colleges and universities, and research institutions.
