Plasma Treatment of Medical Filters

It is no secret that medical manufacturers are turning to plasma treatment to help them improve the performance of their products. Whether used to alter PEEK and PVC to accept time-released medications or even to improve a plastic-to-metal bond in medical tools; plasma treatment has virtually unlimited potential for the medical and pharmaceutical fields. 

Today I wanted to share how we treated blood filters that are used in orthopedic surgery. Our team is proud to help ensure patient safety by treating the filters that inhibit platelet clotting and assist with gas exchange during surgery.

Our client cited they were having difficulty ensuring that blood would adhere to the polymeric filter material during surgery. Without a good bond, there was a real chance that air bubbles could form during surgery, which could lead to the formation of potentially deadly blood clots. 

Through our plasma treatment, we were able to modify the filter so blood would “wet” and create an intimate contact with the tubing. Plasma treatment has resulted in the client’s filters now boasting a greatly-improved molecular adhesion.
