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.

Product Overview

The catheter sliding performance tester is a high-precision professional testing instrument dedicated to evaluating the sliding friction performance of medical tubular products. It is applicable to a full range of interventional medical devices, including urinary catheters, endotracheal tubes, balloon catheters, vascular catheters, drainage tubes, and medical guide wires. The equipment simulates the actual clinical sliding state of catheters through standardized mechanical motion, accurately measures dynamic and static friction coefficients in the sliding process, and intuitively reflects the surface lubricity, coating uniformity and overall usability of catheter products .

Adopting a modular integrated design, the tester realizes automatic sample clamping, constant-temperature simulation testing, intelligent data acquisition and one-click result analysis. It effectively solves the problems of low manual testing efficiency, large data deviation and poor repeatability, and provides reliable technical support for medical device manufacturers, third-party testing institutions and medical research laboratories to optimize product formulas and verify production quality.
