Abstract
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 including a plurality of porous hollow fiber membranes 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 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° C. of 5,000 poise (500 Pa·s)[Chemical Formula 4](Wherein Ris hydrogen or a methyl group, Ris an alkylene group having 1 to 4 carbon atoms, and Ris an alkyl group having 1 to 4 carbon atoms).
