- 摘要：
PROBLEM TO BE SOLVED: To provide a module for hemofiltration or hemodiafiltration dialysis which is a module using hollow fiber membrane which consists of a polysulfone polymer and polyvinylpyrrolidone, is hard to increase pressure of the blood in extracorporeal circulation circuit during a long treatment, has a long life time (membrane duration life) and a reduced albumin loss.
SOLUTION: In a module for extracorporeal circulation of a hollow fiber membrane type, the hollow fiber membrane consists of the polysulfone polymer and polyvinylpyrrolidone and the inside diameter of the hollow fiber membrane is 205-250 &mum, elevated liquid level of the hollow fiber membrane measured by the capillary ascending method is 60 mm-120 mm in terms of the hollow fiber membrane having an inside diameter of 230 &mum, furthermore, when the distance between opening ends of the hollow fiber membrane is defined as L and the minimum inside diameter of the cylindrical container is defined as D, the ratio of L/D is 3.5-6.5, and the sieving coefficient of albumin (Alb-Sc) after 3 hours in the bovine plasma filtering performance test in vitro is 0.0054 or less.
