Catheter strength tester

Instrument Features

The equipment is an industrial-grade testing system for manufacturing quality control, featuring:
1. PLC-controlled automation with touch screen interface
2. Multi-language (Chinese/English) menu operation
3. Force transducer measurement system
4. Intelligent motion control mechanism
5. Built-in printer for instant test result documentation
6. Three-tier password security system
7. Standardized parameter settings including nominal capacity, probe displacement, printing configuration, test modes, calibration functions
8. Real-time display of test parameters: load value, sliding force (initial force, average force, maximum thrust)
9. Automatic failure detection with audible alarm
10. Test report generation including measurement data and pass/fail status

Test Principle

For balloon catheters:
1. Pre-treatment: Immerse in simulated urine for 14 days
2. Apply tensile force to the connection between tip and shaft
3. For side-hole catheters: Apply force specifically to the hole area
4. For non-side-hole catheters: Apply force between shaft and drainage cone interface
5. After loading, inspect for damage to the catheter assembly

• Test preparation:
  　- Pre-soak balloon-type catheters in simulated urine solution for 14 days
  　- Skip soaking step for non-balloon catheters
• Force application:
  　- Apply specified tension to critical connection points
  　- Side-hole catheters: Focus force on hole reinforcement area
  　- Non-side-hole catheters: Apply load between drainage cone and main shaft
• Post-test inspection:
  　- Visually inspect for cracks, detachment, or deformation
  　- Document damage degree according to ISO 5636-12 standard
