Highly efficient manufacture of medical filters: safe casting of blood filters and oxygenators

The membrane on a medical filter must have optimal permeation characteristics for its intended purpose and be highly efficient. It is often manufactured from tufted capillaries. To ensure safe functioning of the membrane, there must be no punctures whatsoever. In particular, the membrane must be securely sealed to the filter’s end plates during manufacture.
Because of the hydrophobic nature of the membrane, reliable adhesion is only possible at that location with appropriate surface modification. In this particular medical technology application, Openair® Plasma has already proven itself for years now—the membrane’s hydrophobic surface is pretreated at precisely the spot where the casting with the filter’s end plates is performed in the next step.
The result is a safe, high-quality processed medical filter.
