1. A method of performing peritoneal dialysis, the method 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, out of the manifold, and through a sorbent cartridge, wherein the manifold comprises a body, internal passageways integrated into the body, a plurality of external ports on the body to allow for fluid communication with conduits or fluid passageways that are external to the body, a plurality of pairs of intra-manifold ports, and a plurality of pump tubes, each pair of the plurality of pairs of intra-manifold ports comprising a first intra-manifold port and a second intra-manifold port that are in fluid communication with one another through a respective one of the pump tubes;
flowing the dialysate out of the dialysate reservoir, back through the manifold along a second flow path that differs from the first flow path, and to a filter;
flowing the dialysate from the second flow path across the filter and into a peritoneum circuit, the filter and peritoneum circuit being in fluid communication with each other via a tube connecting the peritoneum circuit to a first outlet of the filter;
flowing the dialysate through the peritoneum circuit and into a peritoneal cavity;
maintaining the dialysate in the peritoneal cavity for a dwell time, to form spent peritoneal dialysate;
flowing, via a third flow path, the spent peritoneal dialysate out of the peritoneal cavity, through the peritoneum circuit, into the filter, out of the filter through a second outlet of the filter, through the manifold and into the dialysate circuit, the third flow path connecting the peritoneal cavity, the filter via the first and second outlets, the manifold, and the dialysate circuit, in fluid communication with each other; and
further flowing the spent peritoneal dialysate through the third flow path and through the sorbent cartridge to form regenerated dialysate.
