KÜNSTLICHES HERZ-LUNGENKREISLAUFSYSTEM

摘要

To provide an artificial cardiopulmonary circuit system having high heat resistance and excellent blood compatibility. The artificial cardiopulmonary circuit system includes a hollow fiber membrane oxygenator (50) including a plurality of porous hollow fiber membranes (52) for gas exchange having a blood contact part that contacts blood on one side thereof and a gas contact part that contacts a gas on the other side thereof, and a housing (51) that contains the hollow fiber membranes therein. At least a portion of the blood contact part of the hollow fiber membrane oxygenator is coated with a polymer comprising a repeating unit represented by the following general formula (1) as a main structural component and having a viscosity at 65 DEG C of 5,000 poise (500 Pa.s). ÄChemical Formula 4Ü (Wherein R<1> is hydrogen or a methyl group, R<2> is an alkylene group having 1 to 4 carbon atoms, and R<3> is an alkyl group having 1 to 4 carbon atoms).
