  • Anticoagulant composition for use in blood dialysis circuit
    Patent number: 5637081
    Abstract: An anticoagulant composition for a blood dialysis circuit contains a fatty acid derivative in liquid form at ambient temperature, and an antioxidant. The antioxidant is contained in an amount of 0.0001 to 5.0 parts by weight relative to 100 parts by weight of the fatty acid derivative. An air trap chamber device for a blood dialysis circuit contains a vessel for storing blood dialysed by a dialysis unit, an inlet tube for introducing the blood treated with dialysis into a liquid in the vessel selected from the group consisting of a layer of the aforementioned anticoagulant composition, and the blood, a measurement unit for measuring the pressure of air in the vessel lying above the layer of the anticoagulant composition, an adjustment unit for adjusting the pressure of the air and an outlet tube for conducting the blood treated with dialysis out of the vessel.
    Type: Grant

    Date of Patent: June 10, 1997
    Assignee: NOF Corporation
    Inventors: Yasuhisa Noguchi, Toshio Kasama
