Abstract

An apparatus for continuous ambulatory peritoneal dialysis includes a weighing device secured to a support frame, with a suspending structure for hanging a container of fresh dialysis solution from the weighing device. A further support structure suspends from the same weighing device a container or bag for receiving spent dialysis solution. Three conduits are connected together at respective proximal ends, with one conduit being adapted for connection at its distal end to the fresh dialysate container, a second conduit adapted for connection at its distal end to the container for receiving spent dialysis solution, and the third conduit being a patient conduit adapted for communication at its distal end with a patient catheter through which dialysis solution can both enter and leave the peritoneal cavity. Each of the conduits has its respective clamp for selectively permitting and halting fluid flow through the respective conduit. A central processor is operatively associated with the weighing device, and monitors a signal from that device, the signal representing the weight being supported at any given time by the weighing device.
The central processor has data input/output capability by which it can be programmed to carry out a three-stage cycle consisting of a) a fill stage duringwhich the drain conduit is closed, and dialysis solution passes from the container of fresh dialysate through the fill conduit, thence through the patient conduit to the peritoneal cavity of the patient; b) a dwell stage during which the dialysis solution remains in the peritoneal cavity, and c) a drain stage during which the dialysissolution flows from the peritoneal cavity through the patient conduit, thence through the drain conduit to the container for receiving spent dialysis solution. The central processor also includes a real time clock allowing the central processor to track the time taken to fill, the dwell time and the drain time.
