Abstract
An oxygenator having a plurality of porous hollow fiber membranes for gas exchange to treat blood is manufactured by dissolving a silicone compound in an organic solvent having a surface tension of less than 70 dyn/cm to prepare a coating solution, and bringing an inner surface of the hollow fiber membranes into contact with the coating solution under a negative pressure of 50 hPa or more and 150 hPa or less to form a silicone compound-containing coating layer on the inner surface. An antithrombotic polymer compound-containing coat can be provided directly on an outer surface of the hollow fiber membranes.
