Abstract

Official abstract text for this publication.

An oxygenator that inhibits or prevents bubbles in blood from exiting through a blood outlet includes an oxygenator part which performs gas exchange on blood and a heat exchanging part which performs heat exchange on the blood. The oxygenators part has a housing that is generally in a rectangular parallelepiped form, with a hollow fiber membrane bundle positioned in the housing. The hollow fiber membrane bundle is formed by a multiplicity of hollow fiber membranes adapted to perform gas exchange. Blood flows along a blood passage comprised of gaps between the hollow fiber membranes and contacts the surface of the hollow fiber membranes where gas exchange occurs with gas flowing through the lumens of the hollow fiber membranes. In addition, a filter member is arranged on a downstream side of the hollow fiber membrane bundle so that bubbles present in the blood are caught by the filter member.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of performing gas exchange for blood comprising: introducing blood into a blood inlet of a housing in which are positioned a plurality of hollow fiber membranes each having a lumen in communication with a gas inlet and a gas outlet so that the blood flows outside the lumens of the hollow fiber membranes toward a blood outlet; introducing gas into the lumens of the hollow fiber membranes to subject the blood flowing outside the lumens of the hollow…
