HOLLOW FIBER MEMBRANE-TYPE ARTIFICIAL LUNG

摘要

[PROBLEMS] To provide a hollow fiber membrane-type artificial lung which has excellent permeability against an oxygen gas and a carbon dioxide gas and an excellent exchange ability, is hardly eluted into the blood, has excellent strength, and hardly causes the blood coagulation, the plasma leakage or the like. [MEANS FOR SOLVING PROBLEMS] Disclosed is a hollow fiber membrane-type artificial lung which comprises two or more hollow fiber membranes encased in a housing, wherein at least a part of the region of contact with the blood on each of the hollow fiber membranes is covered with a water-insoluble (meth)acrylate copolymer produced by the copolymerization of a hydrophobic (meth)acrylate and a hydrophilic (meth)acrylate at a molar ratio of 50-90:50-10 (wherein the term "water-insoluble" means that the rate of the reduction in the amount of the copolymer after leaving the copolymer in physiological saline in an amount of 99 wt% relative to 1 wt% of the copolymer at 37°C for 30 days is 1 wt% or less).
