Effective removal of gas bubbles and dissolved gases from blood


A German university offers a new method to degas blood extracorporeally, e.g. during surgery, via a cardiotomy reservoir on microporous hollow fibers. The method is very efficient and allows simultaneous oxygenation of the blood. Licencees are sought.

Partner sought

The German university offers interested companies the opportunity to acquire licenses for the invention and for further development of the technology, which has been verified experimentally to date. Sectors of interest are cardiac surgery, mobile emergency service providers or generally the healthcare sector.


During the extracorporeal treatment of blood during surgery both gas bubbles and dissolved toxic gases frequently occur. These pose a life-threatening risk. A German university now offers a solution. Their invention describes a novel cardiotomy reservoir based on the degassing technology of liquids: It consists of three components: a container as a blood volume depot in which a hollow fiber module is arranged, with the blood flowing through the container along the outside of the hollow fibers and the hollow fiber module having a gas inlet and a gas outlet. The gas inlet and outlet can be connected to a vacuum pump in order to degas the blood and thus avoid air bubbles in the blood. If the gas inlet is supplied with oxygen, the blood can be enriched with oxygen at the same time as being vented if an appropriate oxygen flow is selected. The invention can be used in the operating theater as well as in mobile applications. The construction is similar to that of an oxygenator and also uses porous hollow fibers and membranes. The use of negative pressure allows gas bubbles and dissolved gases to be removed from the blood very effectively. If oxygen is also added, the solution can also partially take over the function of an oxygenator. Healthcare companies with activities in cardiac surgery or mobile emergency services are sought for license agreements. Within the collaboration further development is possible.

Advantages and innovations

• Higher efficiency in removing gas bubbles than conventional solutions • Simpler construction • Low cost • Allows simultaneous oxygenation of the blood

How it works

  • Tell us about yourself
  • We’ll discuss with you
  • We put the right partners in touch

EEN help you find the right partner, rather than you going it alone.

Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.

These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.

Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
