medical catheters, and it has extremely important application value in the medical industry. This instrument is mainly used to measure the friThe friction coefficient tester for medical catheters is a professional instrument used to measure the surface friction coefficient of ction coefficient of medical catheters (such as those made of natural rubber, silicone rubber, or polyvinyl chloride PVC) under simulated human environmental conditions, in order to evaluate their impact on patient tissues and comfort during use. By measuring the friction coefficient of the urinary catheter, manufacturers can optimize product design, improve product performance, and reduce discomfort and complications for patients during use.

This tester is usually based on the measurement principles of static friction and dynamic friction coefficient. During the testing process, the catheter is placed in a specific testing device and simulated under normal human body temperature conditions (such as 37 ℃). A standard slider (such as a silicone slider) is used to slide on the surface of the catheter, and the required force is recorded to calculate the friction coefficient. The smaller the friction coefficient, the better the smoothness of the surface of the catheter, and the less damage to the patient's tissue.The testing steps of the friction coefficient tester for medical urinary catheters generally include the following steps:

Preparation stage: Preheat the tester to the set temperature (such as 37 ℃), and prepare the catheter and standard slider to be tested.

Installation sample: Install the catheter into the testing device and secure it to ensure stability during the testing process.

Start testing: Start the tester and slide the standard slider on the surface of the catheter at the set speed, and record the required force.

Data processing: Calculate the friction coefficient based on the recorded force values and slider mass, and evaluate the smoothness performance of the catheter.

The application of the friction coefficient tester for medical urinary catheters is of great significance for improving the quality and safety of medical products. By testing the friction coefficient of the urinary catheter, the degree of damage to the patient's tissue during use can be evaluated, providing scientific basis for product design and production. At the same time, the tester also helps manufacturers optimize their production processes and quality control procedures, enhancing the market competitiveness of their products.
