UNIVERSAL PORTABLE ARTIFICIAL KIDNEY FOR HEMODIALYSIS AND PERITONEAL DIALYSIS

摘要

Methods, systems, and kits are provided for performing hemodialysis, hemodiafiltration, and peritoneal dialysis on a portable machine suitable for both clinical and home use. Peritoneal dialysate can be flowed into and out of the peritoneal cavity, and can also be regenerated within the system, without the need for introducing fresh dialysate. Common hardware and software can be utilized for both peritoneal dialysis and other forms of dialysis such as hemodialysis, hemofiltration, and hemodiafiltration, allowing for facile transition between different dialysis modes using the same dialysis machine.

主权项

1. A method of performing peritoneal dialysis comprising:
flowing dialysate in a dialysate circuit through a first flow path, and into a dialysate reservoir, the first flow path comprising a flow path through a manifold and through a sorbent cartridge; flowing the dialysate out of the dialysate reservoir and through the manifold along a second flow path that differs from the first flow path; flowing the dialysate from the second flow path across at least one filter and into a peritoneum circuit; flowing the dialysate through the peritoneum circuit and into a peritoneal cavity; maintaining the dialysate in the peritoneal cavity; flowing the dialysate out of the peritoneal cavity, through the peritoneum circuit, across the filter, and back into the dialysate circuit; and flowing the dialysate through the manifold along a third flow path and back into the dialysate reservoir, the third flow path comprising a flow path through the sorbent cartridge.
