With the rapid advancement of interventional medical technology, disposable medical catheters and guide wires have been widely applied in clinical diagnosis and treatment. The surface sliding performance of catheters is a core indicator that directly affects clinical operation safety, patient comfort, and product qualification rate. Excessive surface friction may cause tissue irritation, vascular damage, and operational resistance during intubation, bringing potential clinical risks. To standardize the quality inspection of medical catheters and meet global medical device testing standards, our Catheter Sliding Performance Tester is professionally developed for quantitative testing of surface friction coefficient and sliding lubricity of various medical catheters and guide wires, delivering accurate, stable and repeatable test data for medical device R&D, quality control and batch inspection.
