SYSTEMS AND METHODS FOR PRIMING SORBENT-BASED HEMODIALYSIS USING DIALYSIS FLUID
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.

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. - 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.
