Abstract
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.
Claims20
A method of performing peritoneal dialysis comprising:
- flowing dialysate along a first flow path through a manifold and into a dialysate reservoir;
- weighing the dialysate in the dialysate reservoir to obtain a first weight;
- flowing the dialysate out of the reservoir, along a second flow path through the manifold, and into a peritoneal cavity;
- flowing the dialysate out of the peritoneal cavity, along a third flow path through the manifold, and into a drain reservoir;
- weighing the dialysate in the drain reservoir to obtain a second weight;
- and
- flowing the dialysate out of the drain reservoir and along a fourth flow path through the manifold.
