Catheter bending resistance tester

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.
