The Catheter Bending Resistance Tester is a specialized instrument designed to evaluate the bending performance and flow characteristics of catheters. It measures the reduction in flow rate under simulated bending conditions, providing critical data to ensure catheter reliability and safety in clinical applications. The system features real-time force monitoring, automatic result evaluation, and integrated printing for efficient test documentation.
Application
The tester is suitable for a wide range of medical devices, including:
(1) Urinary catheters – testing flow performance under bending to simulate patient conditions.
(2) Drainage catheters – assessing irrigation and drainage cavities.
(3) Infusion catheters – verifying consistent fluid delivery despite bends or kinks.
(4) Preclinical research – evaluating new catheter designs for flexibility and functionality.
(5) Quality control in medical device manufacturing – ensuring compliance with product specifications.
Standards
The instrument is designed to comply with the following standards:
(1) YY/T 0325-2016: Urinary Catheters – Flow and Bending Performance (China)
(2) GB/T 15812.1-2005: Disposable Catheters – General Requirements (China)
Optional references for broader compliance:
(3) ISO 10555-3: Sterile single-use intravascular catheters – Part 3: Single-use catheters for hemodialysis
(4) ASTM F2392: Standard Test Method for Catheter Performance
