    摘要： A dialysate regeneration system for removing contaminants from spent dialysate according to this invention includes a dialysate circulation flow path including a pump (130) that pumps spent dialysate through the dialysate circulation flow path, a first cartridge (140) adapted to remove contaminants from the spent dialysate and being connected to a first cleaning solution flow path including a first cleaning stage (240), a second cartridge (150) adapted to remove urea from the spent dialysate, the second cartridge including semi-permeable hollow fibers adapted for transport of urea across the walls of the semi-permeable hollow fibers and adapted to retain at least calcium, magnesium, and sodium ions in the spent dialysate, the second cartridge being connected to a second cleaning solution flow path including a second cleaning stage (340).

    摘要： A portable peritoneal dialysis system for a patient includes an inlet port for providing inflow to the patient's peritoneal cavity, an outlet port for providing outflow from the patient's peritoneal cavity, and a volume of dialysate for flow into and out of the patient's peritoneal cavity, thereby removing from the dialysate uremic waste metabolites that have diffused into the dialysate. The portable peritoneal dialysis system also includes a closed liquid flow loop, including a pump, for flowing the dialysate into and out of the patient's peritoneal cavity, andan organic- and phosphate-removing stage, including at least one replaceable cartridge in the closed liquid flow loop, the cartridge containing material for removing organic compounds and phosphate from dialysate removed from the patient's peritoneal cavity. The portable peritoneal dialysis system further includes a urea- and ammonia-removing stage, including at least one replaceable cartridge in the closed liquid flow loop, the cartridge containing material for removing urea and ammonia from dialysate removed from the patient's peritoneal cavity, the material being packed around semi-permeable hollow fibers with interior fiber walls that reject cations, thereby retaining cations in the dialysate.
