  • High-Flux Dialysis Membrane With an Improved Separation Behaviour
    Publication number: 20080000828
    Abstract: A hydrophilic, semipermeable hollow-fibre membrane for blood treatment, with an integrally asymmetric structure based on a synthetic polymer. The hollow-fibre membrane possesses on its inner surface a porous separating layer and an open-pored supporting layer adjoining the separating layer, and has an ultrafiltration rate in albumin solution of 25 to 60 ml/(h·m2·mmHg). The hollow-fibre membrane is free from pore-stabilising additives, and has a minimum sieving coefficient for cytochrome c of 0.8 and maximum sieving coefficient for albumin of 0.005.
    Type: Application

  • Dialysis membrane having improved average molecular distance
    Publication number: 20070163949
    Abstract: A hydrophilic semipermeable hollow-fibre membrane for blood treatment, with an integrally asymmetric structure based on a synthetic polymer. The hollow-fibre membrane possesses on its inner surface a separating layer and an adjoining open-pored supporting layer, and has an ultrafiltration rate in albumin solution of 5 to 25 ml/(h·m2·mmHg). The hollow-fibre membrane is free from pore-stabilizing additives and has a maximum sieving coefficient for albumin of 0.005 and a sieving coefficient for cytochrome c that satisfies the equation SCCC?5·10?5·UFRAlb3?0.004·UFRAlb2+1.081·UFRAlb?0.
