Abstract: 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.

Abstract: An apparatus for carrying out peritoneal dialysis includes a central manifold, a receptacle for waste dialysate, means for supporting and heating a plurality of fresh dialysate bags, a first conduit connecting the manifold with the patient catheter, a second conduit for connecting the manifold with the receptacle, and a plurality of additional conduits connecting the manifold individually with a plurality of fresh dialysate bags. The individual conduits can be selectively closed by clamping means controlled by an electronic control, and the latter has an automatic mode which cycles the apparatus through (a) a fill/dwell phase in which the contents of one of the fresh dialysate bags flows into the patient's peritoneum cavity by gravity and remains there, and (b) a drain phase which allows waste dialysate in the patient's peritoneum cavity to drain by gravity into the receptacle. The steps (a) and (b) are repeated for all of the bags until they have been used up.

Abstract: An apparatus for carrying out peritoneal dialysis on a patient having a catheter ending in a patient connector, includes a tubing set in a "Y" configuration, including a first, second and third arm. Each arm has a clamp and terminates in a connector. Along with the "Y" tubing set are also provided a cover for covering and protecting the patient connector after the tubing set has been disconnected, and a closure for sealing a dialysate container after it has been emptied, so that it can be used in a subsequent procedure as a drain bag.

Abstract: A cap and cover are provided as a separate, disposable adjunct to the process of peritoneal dialysis, the cap and cover being connectable either together or to the two connectors, respectively, which join the patient's catheter (or transfer set) to cycler tubing. The cap and cover are designed in such away as to define internal chambers that contain liquid disinfectant, whereby they can be applied to the respective connectors (when the latter are separated) in a safe and sterile manner.

Abstract: This invention relates to a dialysis apparatus having means for supplying dialysis fluid to the peritoneal cavity of a patient and for draining the fluid from the cavity. Valve means are provided to permit a "FILL", a "DWELL", and a "DRAIN" phase to be carried out each cycle. The valve means includes individually occluding cams which control fluid flow through individual tubes.
