Abstract
Systems and methods for hemodialysis or peritoneal dialysis having integrated electrodialysis and electrodeionization capabilities are provided. In an embodiment, the dialysis system includes a carbon source, a urease source, an ED/EDI unit. The carbon source, urease source, and/or the ED/EDI unit can be in the form of removable cartridges.
Claims15
A dialysis fluid system recycling used dialysis fluid, the system comprising:
- a carbon source;
- a urease source in fluid communication with the carbon source;
- and
- an electrodialysis/electrodeionization (“ED/EDI”) unit in fluid communication with at least one of the carbon and urease sources, the ED/EDI unit including
- (i) an ED component, and
- (ii) an EDI component in fluid communication with the ED component, wherein the ED component and the EDI component are separate.
A hemodialysis system recycling used dialysis fluid, the hemodialysis system comprising:
- a blood circuit and a dialysis fluid circuit in fluid communication with a dialyzer;
- a carbon source in the dialysis fluid circuit;
- a urease source in fluid communication with the carbon source;
- and
- an electrodialysis/electrodeionization (“ED/EDI”) unit in fluid communication with at least one of the carbon and urease sources and, the ED/EDI unit including an ED component and an EDI component in fluid communication with the ED component, wherein the ED component and the EDI component are separate.
A peritoneal dialysis system comprising:
- a dialysis fluid recirculation flow path configured to be placed in fluid communication with the peritoneal cavity of a patient;
- a carbon source in the dialysis fluid recirculation flow path;
- a urease source in fluid communication with the carbon source;
- and
- an electrodialyzer/electrodeionization (“ED/EDI”) unit in fluid communication with one of the carbon and urease sources, the ED/EDI unit including
- (i) an ED component, and
- (ii) an EDI component in fluid communication with the ED component, wherein the ED component and the EDI component are separate.
