1. A method of performing peritoneal dialysis comprising:
- flowing dialysate along a first flow path through a manifold and into a dialysate reservoir, the manifold comprising a manifold body that defines a plurality of internal passageways and a plurality of ports providing fluid communication to fluid passageways external to the manifold body, the manifold further comprising a first pumping tube, a second pumping tube, and a third pumping tube each in fluid communication with the plurality of internal passageways, the plurality of internal passageways partially defining each of the first flow path, a second flow path, a third flow path, and a fourth flow path, the first flow path including the first pumping tube;
weighing the dialysate in the dialysate reservoir to obtain a first weight;
flowing the dialysate out of the reservoir, along the second flow path through the manifold, and into a peritoneal cavity, the second flow path including the second pumping tube;
flowing the dialysate out of the peritoneal cavity, along the third flow path through the manifold, and into a drain reservoir, the third flow path including the third pumping tube;
weighing the dialysate in the drain reservoir to obtain a second weight; and
flowing the dialysate out of the drain reservoir and along the fourth flow path through the manifold, the fourth path also including the third pumping tube,wherein the flowing the dialysate along the third flow path comprises pumping the dialysate through the third pumping tube in a first direction, and the flowing the dialysate along the fourth flow path comprises pumping the dialysate through the third pumping tube in a second direction that is opposite the first direction.

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.
