    摘要: Filtration membrane, especially adapted for use in hemofiltration as well as filtration of infusion solutions.
    The membrane, preferably in the form of a hollow fiber, is made of a polymer which is soluble in a polar, non-protonic organic solvent. The most preferred polymer for the membrane material is polyamide. Characterizing for the membrane is high ultrafiltration rates (permeabilities to water) of up to 500 x 10- 4 ml/sec. x cm2 x atm., and impermeability to albumin (M w 68,000).
    The membrane is prepared by extruding a polymer solution with a center liquid under conditions such that the volume of polymer solution to volume of center liquid ratio is within the range of from 2 : 1 to 4 : 1. Simultaneously, the inner diameter to wall thickness ratio of the hollow fiber is preferably correlated to the polymer concentration and is set to 150:75 to 280:75 at a polymer concentration of 5-20%. The most preferred such correlation is 220 : 75 at a polymer concentration of 11 %.
