摘要: The blood flow channel sections of an oxygenator and a blood resevoir are hydrophilized by treatment with an acid, an albumin solution, polyhydroxy methacrylate, corona discharge, plasma or ozone, so that it has highly improved wettability by the priming liquid and the blood to prevent blood foaming. The blood flow channel sections of a medical instrument may be additionally hydrophilized by treatment with a polymer containing hydroxyethyl methacrylate and methyl methacrylate or in addition thereto a poly(oxyethylene)-poly(oxypropylene) block polymer.
