摘要 |
A morphologically heterogenous, hydrophobic polysulfone hollow fiber membrane comprising a sponge-like dense inner surface permeable to molecules of less than or equal to 30,000 Daltons, said inner surface having a fractional surface porosity from 70 to 80%, and an outer surface having large pores from 6 to 16 mu m in diameter and small pores less than 500 ANGSTROM in diameter and a fractional surface porosity from 20 to 30%; a method for producing same and a hemodialysis treatment method and apparatus incorporating same.
