HOLLOW FIBER MEMBRANE FOR HEMATOCATHARSIS AND HOLLOW FIBER MEMBRANE TYPE ARTIFICIAL KIDNEY

摘要

PROBLEM TO BE SOLVED: To provide a hollow fiber membrane for hematocatharsis and a hollow fiber membrane type artificial kidney in which endotoxine is adsorbed on an outer surface and to provide a hollow fiber membrane for hematocatharsis and a hollow fiber membrane type artificial kidney in which a hydrophilic polymer in the hollow fiber membrane is less and a blood platelet is not adsorbed. SOLUTION: In the hollow fiber membrane prepared from a membrane- forming stock solution in which a hydrophilic polymer and a hydrophobic polymer are solvent and mixed in a common solvent, a hollow fiber membrane for hematocatharsis in which a ratio of the hydrophilic polymer is used against the hydrophobic polymer on an outer surface of the hollow fiber membrane is 5-25%.
