Abstract: The invention relates to a testing system and related methods for detecting peritonitis or infection in peritoneal dialysate removed from a patient. The testing system can include a fluid sensor apparatus in a fluid line of a peritoneal dialysis cycler through which spent peritoneal dialysate can be pumped. The fluid sensor apparatus can detect one or more markers associated with peritonitis or infection.
Abstract: A stacked sorbent assembly for use in sorbent dialysis. The stacked sorbent assembly contains two or more interchangeable sorbent pouches that allow for fluid to freely pass into and through the sorbent materials, while keeping the sorbent materials inside the sorbent pouches. Any of the pouches in the sorbent cartridge can be reused and/or recharged.
