ABSTRACT:
This disclosure relates to a transfer device, such as an artificial kidney, which is formed of a plurality of identical plates and wherein between each pair of adjacent plates first and second fluids flow on opposite sides of a transfer membrane. One face of each plate is provided with grooves defining flow passages and the other face of each plate is planar with there being a membrane clamped between unlike faces of adjacent plates and wherein the membrane is deformed into the grooves by fluid flowing along the planar surface of a plate at a pressure higher than the fluid flowing on the opposite side of the membrane in the grooves. The grooved side of the plate is provided with first distribution and collection channels and the planar side side of the plate is provided with second distribution and collection channels, the second channels being more widely spaced than the first channels and thereby providing for an elimination of the possibility of trapping of the fluid flowing on the planar face of each plate beyond its respective distribution and collection channels.
