ABSTRACT:
A membrane type blood oxygenator with a microporous membrane separating blood and air channels, the blood in the blood channels flowing downward to cause any accidentally introduced air bubbles to have an increased residence time in the membrane device owing to buoyancy, the blood being at a pressure sufficiently greater than the air pressure to cause passage of air bubbles through the pores of the microporous membrane to the air side prior to being carried out of the device by flowing blood.
