Introduction
Product Overview
The Catheter Strength Tester is an industrial-grade testing instrument designed for evaluating the mechanical strength and reliability of balloon and non-balloon catheters. It ensures compliance with manufacturing quality standards and assists R&D and production teams in assessing catheter durability under tensile stress.
Equipped with PLC-controlled automation, multi-language touch screen interface, and intelligent motion control, this instrument provides precise measurement of tensile force, sliding force, and overall structural integrity. Real-time data display and automatic report generation allow streamlined quality control and documentation.
Application Fields
Balloon catheters (cardiac, urinary, angioplasty)
Side-hole and non-side-hole drainage catheters
Medical device R&D and prototype testing
Production quality control for catheter manufacturing
Compliance verification with ISO 5636-12 and other medical standards
Hospitals or third-party medical device testing laboratories
Test Principle
The testing procedure simulates the mechanical stresses catheters experience during use:
Pre-Treatment
Balloon-type catheters are immersed in simulated urine for 14 days to mimic real-life conditions.
Non-balloon catheters skip the pre-soak step.
Force Application
Apply tensile force to critical connection points:
Balloon catheters: Tip-to-shaft connection
Side-hole catheters: Focus on hole reinforcement area
Non-side-hole catheters: Shaft-to-drainage cone interface
Post-Test Inspection
Visually check for cracks, detachment, or deformation.
Document the degree of damage according to ISO 5636-12 standards.
This process ensures a standardized evaluation of catheter strength and failure points, providing reliable data for manufacturing quality control.

FAQ
1. What types of catheters can be tested?
The instrument is suitable for balloon-type, side-hole, and non-side-hole catheters, including cardiac, urinary, and drainage catheters.
2. How is the test performed for balloon catheters?
Balloon catheters are pre-soaked in simulated urine for 14 days, then a tensile force is applied at the tip-to-shaft connection to evaluate mechanical integrity.
3. How is damage detected?
Post-test inspection is conducted visually, focusing on cracks, detachment, or deformation. The instrument also provides automatic failure detection with an audible alarm.
4. Does it comply with international standards?
Yes. Testing procedures and reporting follow ISO 5636-12 and other applicable catheter strength standards.
5. Can test results be documented automatically?
Yes. The tester features a built-in printer and software integration to generate test reports including measurement data, pass/fail status, and inspection notes.
