ABSTRACT:
Improved dialyzer construction has elongated tubular casing with enlarged casing ends and longitudinally-extending partitioning that divides its interior into a plurality of generally parallel passageways containing hollow dialysis fibers, the casing ends containing dialyzate flow manifolding and directing means for receiving dialyzate from a supply thereof, directing it from one casing end to the other through one of the passageways around the fibers, and so to and fro through the successive passageways, finally directing the dialyzate out through a discharge opening. The dialyzate flow can in each fiber-containing passageway be counter-current to the flow within the fibers of the liquid being dialyzed. A gas by-pass can be provided in the partitioning at one end to bleed out gas that tends to accumulate at the high point of the to-and-fro dialyzate travel.
