Peritoneal dialysis apparatus
First Claim
1. A peritoneal dialysis apparatus on which a disposable cassette, integrally formed with a fluid distributing diaphragm, a heating portion and a flow path switching portion, is loaded and which is used by connecting to a dialysis fluid container storing a dialysis fluid and a drained fluid container, comprising:
- a body provided with an operating portion and a display a mounting portion provided on the body for detachably mounting the cassette with respect to the body;
pumping actuating means for setting the diaphragm in a positive pressure state and negative pressure state, after the cassette is mounted, to distribute the fluid from the dialysis fluid container and to the drained fluid container;
a heater for heating an amount of dialysis fluid in the heating portion after the cassette is mounted;
flow path switching means for opening/closing the flow path switching portion in order to form a flow path through which the heated dialysis fluid is distributed into a peritoneal cavity of a patient and, after a period of time elapses, the dialysis fluid is sucked and drained from the peritoneal cavity; and
control means connected to the operating portion, the display, said pumping actuating means, said heater, and said flow path switching means for controlling operation of the operating portion, the display, said pumping actuating means, said heater, and said flow path switching means.

Abstract
The invention aims to provide a compact peritoneal dialysis apparatus using a disposable cassette integrally formed with a diaphragm and heating portion, in which a flow path can be switched quietly and a heating ability is high. By using a disposable cassette (8) integrally formed with a diaphragm, heating portion, and flow path switching portion, a predetermined amount of dialysis fluid is heated to a predetermined temperature with the heating portion. Clamps (111-118) for opening/closing a flow path switching portion are provided in order to form flow paths through which the heated peritoneal dialysis fluid is distributed into the peritoneal cavity of a patient almost continuously and is sucked and drained from the peritoneal cavity of the patient. The invention also aims to provide a peritoneal dialysis apparatus with which automatic dialysis treatment can be performed by the patient himself and the operation procedures of which are very clear and easy to understand, so treatment can be performed with optimal conditions, and even if a trouble should occur, it can be coped with easily.

2. A peritoneal dialysis apparatus on which a disposable cassette, integrally formed with a fluid distributing diaphragm, a heating portion forming upper and lower systems of flow paths through a gap and a flow path switching portion, is loaded and which is used by connecting to a dialysis fluid container storing a dialysis fluid and a drained fluid container, comprising:
-
a body provided with an operating portion and a display;
a mounting portion provided on the body for detachably mounting the cassette with respect to the body;
pumping actuating means for setting the diaphragm in a positive pressure state and negative pressure state, after the cassette is mounted, to distribute the fluid from the dialysis fluid container and to the drained fluid container;
three spaced sheet heaters that come into contact with the upper and lower systems of flow paths to perform heating from above and below, thereby heating an amount of dialysis fluid in the heating portion after the cassette is mounted;
flow path switching means for opening/closing the flow path switching portion in order to form a flow path through which the heated dialysis fluid is distributed into a peritoneal cavity of a patient continuously and, after a period of time elapses, the dialysis fluid is sucked and drained from the peritoneal cavity; and
control means connected to the operating portion, the display, said cassette mounting portion, said pumping actuating means, said three spaced sheet heaters, and said flow path switching means to control the operating portion, the display, said cassette mounting portion, said pumping actuating means, said three spaced sheet heaters, and said flow path switching means. - View Dependent Claims (3, 4, 5, 6, 7, 10)
