Catheter Testing Equipment Faces Many Challenges

At one time, catheters and catheterizing equipment were mainly used for people who needed a way to empty their bladders. However, as medical technology continues to advance, catheters deliver tiny instruments and repair devices like arterial stints. They can also bring life-saving antibiotic drugs directly to infected tissues. Because these materials have such important roles in medicine, quality control is essential in their production, and catheter testing equipment must meet many rigid standards today. Here are some of the challenges this technology faces.

Reproducing Actual Test Conditions

One of the biggest challenges facing catheter testing equipment is replicating the human body. For example, if a tube is designed to go into an artery, you can’t use a human being for testing purposes. This takes sophisticated equipment produced by people with a great deal of knowledge on the human body and physics.

An arterial stint is tested for flexion and compression, and a complete catheterizing tube must be tested at the same time, as it pushes through a medium similar to an artery.

Multi-Lumen Catheters

A catheter can deliver blood to diagnostic equipment and can provide intravenous drugs to patients. In fact, some tubes have as many as seven smaller tubes within them. Leak and flow testing multi-lumen tubes take specialized catheter testing equipment. These test machines face the challenge of testing a tube containing many other tubes and must also test each tube within the system. This is not an easy task.

To solve this problem, one leak testing company created a unique instrument allowing the user to program as many as seven testing ports. Each channel can perform leak or flow tests separately. The tester can also customize the pressure decay testing parameters for each channel. This is just one of many challenges modern-day leak test equipment faces.
