Abstract:
An automated peritoneal dialysis system for performing continuous peritoneal dialysis of the type which includes repeated cycles of delivering sterile dialysate to a patient's peritoneal cavity and removing spent dialysate from the patient's cavity wherein said system comprises:a dialysate preparation component providing a generally continuous supply of proportioned osmotic dialysate ready on demand which is effective for dialysis; a fluid circuit connected to said dialysate supply for delivering a flow of the dialysate to the patient and a flow of spent dialysate from the patient to a drain; an inflow line segment in said fluid circuit for delivering said dialysate from said supply to the patient; a dialysate sterilization component having an in-line sterilization filter assembly disposed in said inflow line segment for real-time sterilization of said dialysate in said flow line segment prior to delivery of the dialysate to the patient's peritoneal cavity during the peritoneal dialysis; an outflow line segment included in said fluid circuit for connection to the patient to drain spent dialysate from the peritoneal cavity; a filter integrity test component operatively associated with said sterilization filter assembly for conducting a realtime, in-line integrity test on said filter assembly during peritoneal dialysis and prior to patient delivery to test for a filter failure which would allow contaminants into said dialysate; a control system controlling the filling and draining of the patient's peritoneal cavity to exchange a volume of dialysate until a desired fluid weight has been removed from the patient; a system sterilization component associated with said fluid circuit for sterilizing said fluid circuit including said dialysate sterilization component after a filter failure; and said control system controlling said filter test component and said system sterilization component aperative to test said sterilization filter assembly and sterilize the fluid circuit in the event of a filter failure.
