ABSTRACT:
An apparatus for peritoneal dialysis including a first vessel to contain dialysis fluid and a second vessel to contain spent dialysis fluid. The first and second vessels are connected through a conduit means with the abdominal cavity of a patient, and a pump is located in the conduit means between the first vessel and the abdominal cavity to pump dialysis fluid into the cavity, while a flow control means, such as a valve, is located in the conduit means between the abdominal cavity and the second vessel to control the flow of dialysis fluid being removed from the patient. A branch conduit interconnects the conduit means at a location between the first vessel and the abdominal cavity and the branch conduit is provided with a third overflow vessel located at a higher level than the abdominal cavity. A weighing mechanism is provided for weighing all three vessels, and a control unit is responsive to the weight as determined by the weighing mechanism for controlling operation of the pump and the valve means to obtain the desired flow of dialysis fluid through the conduit means.
