Abstract
An apparatus and method for use in blood dialysis. The apparatus includes: two dialyzers each containing a semipermeable membrane that divides the dialyzer into a blood compartment and a dialysate compartment; a blood compartment connecting line connecting the blood compartments of the dialyzers together in series; blood connecting lines for connecting the blood compartments to the vascular system of a patient; a dialysate compartment connecting unit connecting the dialysate compartments of the dialyzers together in series; and dialysate connecting lines for connecting the dialysate compartments to a dialysis machine. The dialysate compartment connecting unit includes an adjustable flow varying device for controllably setting the rate of the flow of dialysate through the connecting unit.
