Applications
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.
Standards
YY/T 1536-2017:Catheters other than intravascular catheters—Standard test model for evaluating the surface sliding performance
GB/T:National Recommended Standards of the People's Republic of China
ASTM:Standards of American Society for Testing and Materials

Test Procedures
Install the tubing clamps into the clamping grooves of the clamping system. Adjust the distance between the two sliding clamps to the specified clamping distance, and then tighten the clamps, ensuring a good fit between the tubing clamps. Pass one end of the test tubing through the two tubing clamps from bottom to top, with the upper clamp of the testing instrument holding the tubing head. Insert the remaining portion of the tubing into a round tube filled with water, allowing it to immerse naturally for the manufacturer's recommended time. Adjust the position of the two sliding clamps in the grooves so that the tubing is centered. Start the testing instrument to allow the tubing to pass through the silicone pad a sufficient distance, and record the force versus displacement curve. Report the result as the average force value of the wetted section of the tubing on the curve.
