Abstract:
1. A medical liquid supply device comprising: a liquid supply path, the liquid supply path having a distal end to which a liquid is supplied; a suction path, the suction path having a distal end through which a material is suctioned; a liquid supply driver which is configured to supply the liquid via the liquid supply path when being driven; a suction driver which is configured to perform suction via the suction path when being driven; a communication path having a first end which is communicated with the liquid supply path at a position between the liquid supply driver and the distal end of the liquid supply path, and having a second end which is communicated with the suction path at a position between the suction driver and the distal end of the suction path; a liquid supply mode input that is configured to select a liquid-supply ON mode in which the liquid is supplied from the distal end of the liquid supply path; and a control unit which is configured to control the liquid supply driver and the suction driver in accordance with whether the liquid-supply ON mode is selected, the control unit being configured to control the liquid supply driver to supply liquid such that liquid flows from the liquid supply driver in the liquid supply path regardless of whether the liquid-supply ON mode is selected, the control unit being configured to control the liquid supply driver and the suction driver such that all the liquid that flows from the liquid supply driver flows into the communication path and is suctioned by the suction driver through the suction path when the liquid-supply ON mode is not selected, and the control unit being configured to control the liquid supply driver and the suction driver such that at least a part of the liquid that flows from the liquid supply driver does not flow into the communication path and is supplied from the distal end of the liquid supply path when the liquid-supply ON mode is selected.
