The Pioneer of Modern Leak Testing

Catheter Testing Using the SprintMD


Catheters are used to diagnose and treat many different medical conditions. This creates a need for a wide range of catheter designs. As such, testing them to ensure safety and reliability is of critical importance. However, due to the range of tests that must be completed, this process can be lengthy and challenging. Multi-lumen catheters, for example, are intended for multiple configurations, and might be used for concurrent treatments, such as hemodialysis, pacing, drug delivery, CVC, PICC, and more.

Manufacturers of multi-lumen catheters face a demanding task during the quality testing process. Many regulatory bodies, including the FDA in the United States, require leak testers to check each lumen in the catheter to make certain nothing leaks. Each passageway must also be tested for possible blockage or partial occlusion.

Added to these concerns, the tester must be cost-effective so numerous stations can be implemented for increased production output.  This requirement has led some manufacturers to custom-build catheter testers in-house, assembling them from computers and various measuring equipment, so that they often become an unmanageable collection of difficult-to-operate and difficult-to-maintain components.


Uson’s SprintmD leak tester is designed specifically to meet the challenges of medical device manufacturers and is ideal for leak testing catheters. It can be configured as a four-channel sequential tester incorporating everything needed to test multi-lumen catheters for leakage and occlusion. The instrument checks for leaks in fittings, leaks through the outside catheter wall, inter-lumen leaks, and occlusion with each lumen. It also checks for occlusion to the distal exit ports.
