POROUS HOLLOW-FIBER MEMBRANE WITH SUPERIOR STABLE PERMEABILITY

摘要

PROBLEM TO BE SOLVED: To provide a blood purifier having high water permiation performance and used for treatment of chronic renal failure, which has stable treatment performance not influenced by concentration of the blood. SOLUTION: This porous hollow-fiber membrane is provided for the blood purifier capable of exerting a certain level of performance despite of conditions of the blood and the performance is attained by controlling the filling state and the degree of freedom of substrate polymers. This hollow fiber membrane having such characteristic and suited to the blood purification membrane is acquired by controlling the membrane-forming conditions. COPYRIGHT: (C)2009,JPO&INPIT
