First Claim
1. A hemodialysis system comprising:
- a dialyzer;
a blood circuit including a blood pump in fluid communication with the dialyzer;
a dialysate circuit including a dialysate circulation pump in fluid communication with the dialyzer, at least a portion of the dialysate circuit incorporated into a disposable dialysate cassette;
a sorbent cartridge for cleaning used dialysate flowing in the dialysate circuit;
a reservoir holding an initial supply of dialysate;
a reservoir pump in fluid communication with the dialysate circuit and the reservoir;
a supply of infusate; and
an infusate pump in fluid communication with the dialysate circuit and the supply of infusate.
