Abstract
Peritoneal dialysis is performed by circulating peritoneal dialysis solution through a peritoneal cavity by conveying peritoneal dialysis solution through an inlet branch into the peritoneal cavity and by withdrawing peritoneal dialysis solution through an outlet branch from the peritoneal cavity. Peritoneal dialysis solution in the outlet branch is conveyed along a first side of a porous membrane while conveying a regeneration solution containing at least one regenerating agent along a second side of the porous membrane. The membrane is configured to transport the regenerating agent into the peritoneal dialysis solution while transporting waste from the peritoneal dialysis solution into the regeneration solution, thereby creating a regenerated peritoneal dialysis solution. The regenerated peritoneal dialysis solution is circulated through the inlet branch into the peritoneal cavity.
