Document Type and Number:
Japanese Patent JP4533850
Kind Code:
B2
Abstract:
An oxygenator (1) is provided which can prevent the bubbles in blood from exiting through a blood outlet. An oxygenator (1) includes an oxygenators part (1A) for performing gas exchange on blood and a heat exchanging part (1B) for performing heat exchange on blood. The oxygenators part has a housing (2) wholly nearly in a rectangular parallelepiped form. The housing (2) receives therein a hollow fiber membrane bundle (3) formed by integrating together a multiplicity of hollow fiber membranes (31) serving for gas exchange and a filter member (4) formed by a mesh or so. The hollow fiber membrane bundle (3) wholly takes nearly a rectangular parallelepiped form. The filter member (4) is arranged on a downstream side of the hollow fiber membrane bundle (3). The blood, flowing from an upstream to downstream of the blood passage formed in the gaps (33) of between the hollow fiber membranes, goes into contact with a surface of the hollow fiber membranes where gas exchange is made with the gas flowing the lumens (32) of the hollow fiber membranes. Furthermore, the bubbles present in the blood are to be caught by the filter member (4).
