Abstract

A method, system and apparatus for performing peritoneal dialysis are provided. To this end, in part, a peritoneal dialysis apparatus is provided that includes a body provided with an operating portion and a display, a mounting portion provided on the body for detachably mounting a cassette, a pumping actuating device for setting a diaphragm in a positive and negative pressure state to distribute fluid from the dialysis fluid container to the drained fluid container, and a heater for heating an amount of dialysis fluid. The apparatus further includes a flow path switching device for opening/closing a flow path switching portion in order to form a flow path through which the heated dialysis fluid is distributed into and drained from a peritoneal cavity of a patient, and a controller for controlling operation of the operating portion, the display, the pumping actuating device, the heater, and the flow path switching device.

Claims

1. A system for providing dialysis comprising;

a fluid pathway for coupling a patient to the dialysis system;

a pump for pumping dialysis fluid to and from the patient;

a heater for heating the fluid that flows to and from the patient;

a controller for controlling the heater and the pump; and

a single housing for the pump, heater and controller;

the housing including a display device for displaying selected characteristics of a therapy provided by the system.
