Catheter Sliding Performance Tester
Category：Medical Catheter tester
Introduction
The catheter sliding performance tester is a precision instrument specifically designed to evaluate the sliding performance of medical devices – catheters. Its main purpose is to assess the surface sliding performance of disposable non – intravascular catheters, ensuring that when used in the human body, the catheters can reduce friction, alleviate patient pain, and achieve smooth insertion and infection prevention effects. Meanwhile, this tester also provides important evidence for the quality control and safety evaluation of catheters. In addition, it can be used for multiple tests such as the bending performance and tensile performance of catheters, providing clinicians with more comprehensive and in – depth data on catheter performance, further ensuring the safety and effectiveness of surgical procedures.
