Medical Device Leak Testing

The medical device industry faces several unique challenges that other markets don’t. Product failure in the medical device industry impacts patient comfort and can place their lives at risk.  Because of this, manufacturers are required to conduct thorough medical device diagnostic testing to ensure products meet strict federal criteria for health and safety.

Medical Device Diagnostic Testing Complexities

Medical devices come in different sizes and often feature complex geometries such as tubes, valves and other components that can make equipment testing more challenging. The flexibility and elasticity of silicone and other common medical device materials can also impact test pressure.  
 
To address the complexities, medical device leak testers must provide effective sealing and the correct amount of pressure and sensitivity to produce accurate test results. Choosing the correct equipment medical leak testing method is also important.

Medical Leak Testing Using Pressure Decay and Mass Flow Equipment

Products from CTS include a variety of medical device diagnostic testing solutions that provide reliable results in fast cycle times. The two most common methods of medical leak testing include mass flow and pressure decay, both of which can be conducted using our medical device leak testers.

What Is the Difference Between Mass Flow and Pressure Decay Medical Leak Testing?

Pressure decay equipment testing involves pressurizing the component and then isolating it from the pressure source. If a leak is present, the air will move from a high-pressure area to a low-pressure area, triggering a decrease in overall pressure that is then measured by the equipment.
 
Mass flow leak testing involves pressurizing the component and then monitoring the amount of air flowing into the part. The medical device leak tester then detects the presence of a leak by measuring how much air is required to maintain the internal pressure. The higher the volume of air required, the larger the leak.

Equipment Testing Options for Catheters, Bags and Other Medical Devices

We will work with you to determine which equipment and testing method is right for your unique medical device leak testing needs. Contact us to discuss your medical equipment testing requirements.
  • Catheter Testing Solutions: Cincinnati Test Systems offers many catheter testing options, including leak test devices for balloon catheters and multi-lumen catheters.
    • Compliant Balloon Catheters: Used in enteral feeding, tracheotomy tubes, occlusion (vascular/bronchial), drainage (urinary/chest), and more. This type of medical device leak testing often uses a combination of pressure and vacuum decay for verification of inflation/deflation, ramp to burst event, and dilation curve information.
    • Non-Compliant Balloon Catheters: Used in stent delivery, PTA/PTCA, dilation, and more. Catheter testing is often performed using positive pressure and/or vacuum decay testing and verification of inflation/deflation.
    • Multi-Lumen Catheters: Used in hemodialysis, diagnostics, pacing, drug delivery, CVC, PICC, and various other applications. These catheters are often tested using both pressure decay for leak testing and mass flow using multi-port instruments for blockage testing on each individual lumen.
  • Bags: Used for IV/saline, hemodialysis, blood transfer, urinary/waste collection, and more. Bag testing is often performed using pressure decay with restraining plates and bag functional testing using ramp to burst event.
  • Check Valves & Pressure Relief Valves: Used in drug/fluid delivery, hemodialysis, blood transfer, and more. Check valve testing is often performed using pressure decay (leak) and cracking/open pressure utilizing ramp to open event (functional).
  • Tubing Sets: Used in drug and solution delivery, blood transfer, and more. Set testing is often performed using pressure and/or vacuum decay testing and occlusion testing.
  • Sheath IntroducersUsed for guidewire and catheter entry into blood vessels. Testing often includes pressure and vacuum decay testing as well as occlusion testing.
