ABSTRACT:
Disclosed is a method of hemodialysis and a modification for existing hemodialyzers to facilitate use of the method. A highly porous membrane is utilized in a single pass hemodialysis system. The membrane is freely supported, such that it distends in use to maintain a constant transmembrane pressure over its entire surface. The modification to existing dialyzers includes the use of a highly porous membrane, in combination with a transmembrane pressure sensor, which controls the dialysate output flow to maintain a precise transmembrane pressure.
