First Claim
Patent Images
1. A method for priming a hemodialysis treatment comprising:
- providing a sorbent cartridge for cleaning spent dialysate fluid returning from a dialyzer;
preparing a batch of dialysate in a quantity commensurate with being recycled through the sorbent cartridge multiple times;
priming a dialysate circuit in fluid communication with the dialyzer using the batch of dialysate; and
priming a blood circuit in fluid communication with the dialyzer using the batch of dialysate and reversing a blood pump at least one time to pump dialysate from the batch of dialysate.

19. A dialysis system comprising:
-
a batch container; a sorbent cartridge; first and second dialysate pumps; a blood pump; a dialyzer; a dialysate circuit (i) in fluid communication with the batch container, the sorbent cartridge, and the dialyzer and (ii) in operable communication with the first and second dialysate pumps; a blood circuit (i) in fluid communication with the dialyzer and (ii) in operable communication with the blood pump; and at least one processor configured to operate a priming sequence in which dialysate prepared in the batch container is flowed to prime both the dialysate and blood circuits, and wherein the blood circuit is primed by reversing the blood pump at least one time. - View Dependent Claims (20, 21, 22)

23. A dialysis system comprising:
-
a batch container; a sorbent cartridge; first and second dialysate pumps; a blood pump; a dialyzer; a dialysate circuit (i) in fluid communication with the batch container, the sorbent cartridge, and the dialyzer and (ii) in operable communication with the first and second dialysate pumps; a blood circuit (i) in fluid communication with the dialyzer, and (ii) in operable communication with the blood pump; a fluid line connected to an arterial line of the blood circuit upstream of the dialyzer; a valve in the fluid line; and at least one processor configured to operate a sequence in which the valve is opened to enable dialysate to enter the blood circuit upstream of the dialyzer to prime the blood circuit.
