PROBLEM TO BE SOLVED: To simplify and miniaturize a mechanism by pressurizing a fluid stored in a first container, feeding it to a prescribed portion, decompressing a second container, and sucking and forcefully storing the fluid at the prescribed portion in the second container. SOLUTION: A control arithmetic section 16 controls a series of actions, judges whether the connection states of various sections are normal or not, and sends an action instruction signal to an output display means 19 when the connection states are normal. Prior to a dialysis start, the control arithmetic section 16 sends an instruction to a decompressing means 8 to drive a displacement type pump 27b, and decompresses the decompressed chamber 5 of a drainage container 6. Normally closed valves 12, 13 are closed, and normally closed valves 14, 15 are opened. The body storage drainage is forcefully recovered into a drainage recovery chamber 4. A pressurizing means 7 is driven to open the normally closed valves 12, 15 and to close the normally closed valves 13, 14. A dialyzing fluid in a dialyzing fluid container 1a is fed into the abdominal cavity. A mechanism can be simplified and miniaturized according to this constitution.
