Abstract
A pump assembly for ambulatory peritoneal dialysis transfer procedures includes a portable power supply geared to drive a high-volume peristaltic pump. A cassette of the pump comprises an encasement; tubing including an inner portion positioned within the encasement, a patient-side portion for connection to an indwelling peritoneal dialysis catheter and an opposing portion connectable to a system for containment and communication of a peritoneal dialysis solution which may be one single-compartment bag assembly; a safety valve for selectively occluding and permitting the communication of the solution through the inner portion; and a filter preferably interposed along the patient-side portion which filters air and particles from peritoneal dialysate that is flowing toward a patient and which allows peritoneal dialysate to flow substantially freely and unfiltered away from the patient.
