Abstract
A hemodialysis unit has an integral partition disposed across the length and width of the interior of the dialysate chamber separating the dialysate chamber into two subchambers. The first of the two dialysate subchambers has a blood perfusion unit floor and the second dialysate subchamber has a blood perfusion unit ceiling respectively, both subchambers having the opposed exterior length and width margins of the blood perfusion unit sealed to the opposed bonding edges of the dialysate chamber. The cross sectional areas of the two dialysate subchambers so formed are adaptively sized to provide a high velocity flow of dialysate solution over the length of the two subchambers, providing a more rapid sweep of the diffusional boundary layer from the exterior of the two opposed faces of the blood perfusion unit, providing a high rate of removal of waste excreta products from a patient's blood.
