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
Features
(1) Programmable controller with touch screen interface for easy parameter setup.
(2) Real-time monitoring of force and flow data.
(3) Automatic result evaluation with buzzer alarm for unqualified tests.
(4) Integrated printer for immediate documentation of test results.
(5) Adjustable fixtures to accommodate various catheter sizes and types.
(6) Automatic circulation of water pump to simulate physiological conditions.
(7) Dual language interface (Chinese/English) for global usability.

Test Procedures
(1) Install the catheter into the test fixture, ensuring proper alignment.
(2) Adjust the static water level using the automatic circulation pump.
(3) Set test parameters via the touch screen: nominal capacity, flow measurement, test duration, calibration, and verification.
(4) Start the test; the system applies bending force to the catheter loop while measuring flow reduction.
(5) Monitor real-time force and flow data on the screen.
(6) The system automatically evaluates results, sounds an alarm if the catheter fails, and prints a report for record-keeping.
Maintenance Information
(1) Regularly clean the water circulation system and fixtures to prevent debris buildup.
(2) Calibrate the flow measurement system periodically to ensure accuracy.
(3) Avoid prolonged exposure to direct sunlight or excessive moisture.
(4) Inspect electrical connections and sensors for wear or damage.
(5) Follow standard electrical safety procedures during operation.
