ABSTRACT:
A hydrophilic semipermeable hollow-fibre membrane for blood treatment, with an integrally asymmetric structure based on a synthetic polymer. The hollow-fiber membrane possess 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 fiber membrane is free from pore-stabilizing additives and has a maximum sieving coefficient for albumin of 0.005 and a sieving coefficient of cytochrome c that satisfies the equationin-line-formulae description="In-line Formulae" end="lead"?SCcc≧5·10−5·UFRAlb3−0.004·UFRAlb2+0.1081·UFRAlb−0.25.in-line-formulae description="In-line Formulae" end="tail"?
