    摘要: A portable hemodialysis system is provided including a dialyzer, a closed loop blood flow path which transports blood from a patient through the dialyzer and back to the patient, and a closed loop dialysate flow path which transports dialysate through the dialyzer. Preferably, the hemodialysis system includes a sorbent filter in the dialysate flow path. Furthermore, the hemodialysis machine includes a blood pump, and a pair of dialysate pumps. A processor controls the flow of blood through the blood flow path, and the processor controls the flow of dialysate through the dialysate flow path. In addition, the processor stores a patient treatment plan wherein the flow rate of dialysate reduces throughout treatment to maximize the amount of urea removed by the sorbent filter.

    摘要: Sorbent regeneration systems for use in dialysis machines are described. Sorbent regeneration cartridges may include a layer of urease, a layer of acid zirconium phosphate, and a layer of sodium zirconium phosphate. An apparatus for conducting dialysis may include a sorbent cartridge, and a dialyzer in fluid communication with the sorbent cartridge, wherein spent dialysate passes from the dialyzer to and through the sorbent cartridge, and wherein the sorbent cartridge comprises a layer of urease, a layer of acid zirconium phosphate, and a layer of sodium zirconium phosphate. The urease may be immobilized to or associated with a carrier.

    摘要: A portable hemodialysis system is provided including a dialyzer, a closed loop blood flow path, a closed loop dialysate flow path, a blood pump, and a pair of dialysate pumps. A processor controls the flow of blood through the blood flow path, and the processor controls the flow of dialysate through the dialysate flow path. In addition, the processor stores a preprogrammed patient treatment plan wherein the flow rate of the dialysate through the dialysate flow path reduces throughout the patient's treatment to maximize the amount of urea removed by the sorbent filter. In alternative embodiments, the processor stores a patient treatment plan wherein the dialysate flow rate increases throughout the patient's treatment. In still alternative embodiments, the processor stores a patient treatment plan wherein the flow rate of the dialysate through the dialysate flow path both increases and decreases throughout the patient's treatment.
