Catheter Flexibility Tester

• 

Main Uses

The catheter flexibility tester is mainly used to evaluate the flexibility and durability of catheters or guidewires during bending or twisting processes. This equipment is widely applied in medical, industrial and other fields to ensure the safety and reliability of catheters during use. In the medical field, it is particularly suitable for evaluating the flexibility and durability of medical catheters such as blood vessel catheters, urinary catheters, and biliary catheters, ensuring that they will not cause harm to patients during use. In the industrial field, it can be used to assess the flexibility of catheters transporting fluids, gases and other media in different environments, ensuring their good performance during use. In addition, in fields such as aviation and automotive, the catheter flexibility tester is also used to evaluate the flexibility and durability of catheters under different temperature and pressure conditions.

Technical Parameters

Testing Range: Force Range: Usually 0 - 10 kilograms or more, specifically depending on the model and specifications of the tester. Testing Stroke: The strokes in the vertical and horizontal directions may vary. For example, the vertical stroke could be 0 - 300mm, and the horizontal stroke could be 0 - 700mm, etc. Testing Speed: Press - down Speed: Usually adjustable within the range of 0 - 300mm/min. Wire - drawing Speed: Some testers may have a wire - drawing function, with a speed of 0 - 500mm/min or faster. Catheter Clamping Method: Usually, pneumatic clamping or mechanical clamping methods are adopted to ensure the stability and accuracy of the catheter during the testing process. Control System: Usually, a PLC control system is adopted, featuring high precision and stability. The operation interface may be equipped with a color touch screen, which is convenient for users to make settings and operations.
