The Catheter Friction Tester is a precision instrument used to measure the surface friction properties of various tubular materials. Employing advanced force sensing technology and a precise motion control system, it accurately determines the static and dynamic friction coefficients of pipes under different conditions.
The catheter friction performance tester is a professional instrument used to detect the surface slipperiness of medical catheters, and it has a wide range of applications, mainly including the following aspects: Medical Device R & D: During the R & D of new - type catheter - based medical devices, the tester can be used to evaluate the friction performance of catheters made of different materials and with different design schemes, providing a basis for product quality control. Meanwhile, by selecting catheters with appropriate frictional force through testing, product design can be optimized and product performance can be improved. Clinical Assessment: In clinical practice, the tester can provide parameter data for doctors, helping them select suitable catheters, thus improving the safety and effectiveness of treatment. Academic Research: Academic institutions and research units can use the tester to conduct relevant basic research, and deeply explore the influence mechanism of friction performance on the effects of interventional treatment.
