Abstract: A peritoneal dialysis machine that includes a base, a boiling vessel, a condenser, a fluid storage vessel, a sterilizing UV lamp, a fluid mixer, a dialysate cassette, a boiling vessel demineralizing system, and an optional fluid storage vessel rinsing system. The peritoneal dialysis machine automatically generates a predetermined volume of distilled water each day. Pre-weighed quantities of low-endotoxin dialysate chemicals are then mixed into the warm distilled water, and the resulting peritoneal dialysate is sterilized via exposure to ultraviolet radiation. These actions are complete by the patient's indicated bed time. The peritoneal dialysis machine then exchanges spent peritoneal dialysate in the user's peritoneal cavity with fresh peritoneal dialysate throughout the night, causing each infusion of fresh dialysate to dwell in the user's peritoneal cavity for a predetermined time. All spent fluids are routed from the peritoneal dialysis machine to a toilet or a sewer drain.

Abstract: The present invention is a sorbent-based portable peritoneal dialysis system that uses 2.5 liters of tap water per day. The system comprises a control unit, a sterilized disposable cassette, a sterilized disposable glucose solution cartridge and a sterilized sorbent cartridge, and a three liter removable fluid storage container. A supply of concentrated electrolytes solution and a venting sterilizing dialysate filter are contained in the cassette. The glucose and sorbent cartridges snap into the cassette, which snaps onto the control unit. The cartridges are replaced daily, and the cassette is replaced weekly. During use (typically while the patient sleeps at night), the system removes all spent dialysate from the patient every two hours. The system then returns two liters of regenerated, sterilized dialysate to the patient. The patient discards the spent dialysate in the morning.
