Abstract: An automatic cycler for performing Continuous Cycling Peritoneal Dialysis (CCPD) and Intermittent Peritoneal Dialysis (IPD) is provided. The apparatus of the present invention is a safe and convenient cycler apparatus for performing peritoneal dialysis in either home or clinical environment. The apparatus provides a stable base by storing dialysate at a relatively low position. Tubing administration set length is reduced to a minimum by the use of individual, separated valves and by the elimination of redundant, duplicate tube sections. Administration set complexity is reduced by the use of a conventional design dialysate container for heating and weighing of an infusing dialysate dosage. The apparatus allows for gravity feed to a patient with an optional capability of adjusting the pressure head for the gravity feed.
