<p>Provided are a medical-solution reservoir that is filled with at least a medical solution and that feeds the medical solution to a medical solution administration side; a pump that discharges to the medical-solution reservoir a driving liquid that is used in pushing the medical solution filled in the medical-solution reservoir; and a driving liquid reservoir that is filled with the driving liquid. The medical-solution reservoir forms a pipe in which the driving liquid discharged by the pump enters from an opening on one end so that the medical solution is pushed to the medical solution administration side from an opening on other end of the pipe. A marker is placed between the driving liquid and the medical solution, the marker being used in detecting a pushed quantity of the medical solution pushed by the driving liquid. As a result, it becomes possible to know the state of medical solution administration and administer a definite quantity of the medical solution that needs to be administered within a predetermined time period.</p> |
