HOLLOW FIBER MEMBRANE EXTERNAL BLOOD PERFUSION TYPE ARTIFICIAL LUNG

摘要

PROBLEM TO BE SOLVED: To provide a hollow fiber membrane external blood perfusion type artificial lung which lessens the tacky adhesion and activation of platelets and lessens the leakage of plasma components. SOLUTION: The hollow fiber membrane external blood perfusion type artificial lung 1 is formed lay housing many porous hollow fiber membranes 3 for gas exchange into a housing 2 and is the artificial lung of a type in which blood flows to the outside surface side of the hollow fiber membranes 3 and oxygen-contg. gas flows in the hollow fiber membranes 3. The outside surfaces or outside surface layers of the hollow fiber membranes 3 are coated with a synthetic high polymer consisting essentially of alkoxy alkyl (meth)acrylate consisting of 1-4C alkoxy groups and 1-4C alkyl groups. The synthetic high polymer does not substantially exist in the inside layers of the hollow fiber membranes 3 or the inside surface layers of the hollow fiber membranes.
