An automated peritoneal dialysis machine is provided which is capable of selecting and changing the composition of dialysate delivered to a patient in the course of treatment to meet specific physiological needs. The apparatus includes means for metering solutions of osmotic agent, electrolytes and other desired dialysate components from separate solution containers into mixing chamber means for combination in desired proportions. The means for delivery of fresh dialysis fluid to a patient and for removing spent dialysis fluid from the patient includes means for monitoring intraperitoneal pressure and other conditions of the fluid in the peritoneum and electronic control means responsible to the signal of monitoring means for controlling rates of dialysate infusion and removal.

[ I claim:] [1.]1. Apparatus for carrying out peritoneal dialysis on a patient whose peritoneal cavity is in communication with at least one patient catheter, said apparatus comprising:(a) a manifold comprising a plurality of liquid input/output ports;(b) occlusion means for selectively sealing off and re-opening communication between any one or more of said input/output ports and the other input/output ports of the manifold;(c) a patient conduit line for connecting at least a second one of said input/output ports to said patient catheter;(d) conduit lines for connecting others of said input/output ports to respective container bags of dialysate solution components; and(e) metering means in communication with at least a first one of said input/output ports, operable to withdraw and measure volume of a selected quantity of liquid from said manifold and to allow the mixing together of selected quantities of components of said dialysate solution to provide a dialysis solution of a desired final formulation; and(f) electronic control and sequencing means for controlling said occlusion means and said metering means, operable to cause the selected volume of each of selected ones of said components to be withdrawn by said metering means and further operable to cause a selected volume of said dialysis solution of a desired final formulation to be injected through said patient conduit line into a peritoneal cavity line of the patient in a FILL phase and, after a first selected time in a DWELL phase, to be withdrawn from the peritoneal cavity into said metering means.
