    Abstract: An antithrombotic blood treating system comprising a combination of a permselective hollow fiber membrane containing a copolymer having a polyethylene oxide unit; a header having a blood-contacting surface coated with either a heparinized hydrophilic copolymer containing vinyl chloride as the constituent or a hydrophilic copolymer having a polyethylene oxide unit; a catheter; and a circuit. It becomes possible for the first time to conduct extracorporeal circulation for a long period of time without the necessity for internally administering heparin by imparting an antithrombotic property to the entire blood-contacting surface.

    Abstract: This invention provides method and membrane for hemodialysis which has a total protein permeability of not more than 0.2%, and has a reduction rate of beta 2-microglobulin of not less than 5%. The hemodialysis membrane of the present invention selectively removes beta 2-microglobulin which was shown to cause some long-term complications such as carpel tunnel syndrome in the patients undergoing hemodialysis, while preventing the leakage of useful proteins.
