A syringe pump, comprising: a syringe mounting part on which to mount an outer cylinder of a syringe; a slider for holding a plunger of the syringe mounted on the syringe mounting part; a clamp which contacts an upper surface of the outer cylinder mounted on the syringe mounting part and which thereby fixes the outer cylinder; an outer cylinder detecting part (40a, 40b) for detecting that the outer cylinder is mounted on the syringe mounting part; a plunger detecting part for detecting that the plunger is held by the slider; a clamp detecting part for detecting that the outer cylinder is fixed by the clamp; a display unit for displaying predetermined information; and a control unit for controlling the display of the display unit; whereby the control unit is connected to the outer cylinder detecting part (40a, 40b), the plunger detecting part and the clamp detecting part, to produce detection information therefrom, and is inputted with the detection information; wherein the control unit is configured to perform a control, based on the detection information, for displaying guidance in a character information display section and/or graphic display section showing respective changes between the states of the syringe pump before and after the operation of mounting the outer cylinder onto the syringe mounting part, the operation of holding the plunger by the slider and the operation of fixing the outer cylinder by the clamp. a syringe mounting part on which to mount an outer cylinder of a syringe; a slider for holding a plunger of the syringe mounted on the syringe mounting part; a clamp which contacts an upper surface of the outer cylinder mounted on the syringe mounting part and which thereby fixes the outer cylinder; an outer cylinder detecting part (40a, 40b) for detecting that the outer cylinder is mounted on the syringe mounting part; a plunger detecting part for detecting that the plunger is held by the slider; a clamp detecting part for detecting that the outer cylinder is fixed by the clamp; a display unit for displaying predetermined information; and a control unit for controlling the display of the display unit; whereby the control unit is connected to the outer cylinder detecting part (40a, 40b), the plunger detecting part and the clamp detecting part, to produce detection information therefrom, and is inputted with the detection information; wherein the control unit is configured to perform a control, based on the detection information, for displaying guidance in a character information display section and/or graphic display section showing respective changes between the states of the syringe pump before and after the operation of mounting the outer cylinder onto the syringe mounting part, the operation of holding the plunger by the slider and the operation of fixing the outer cylinder by the clamp. an outer cylinder detecting part (40a, 40b) for detecting that the outer cylinder is mounted on the syringe mounting part; a plunger detecting part for detecting that the plunger is held by the slider; a clamp detecting part for detecting that the outer cylinder is fixed by the clamp; a display unit for displaying predetermined information; and a control unit for controlling the display of the display unit; whereby the control unit is connected to the outer cylinder detecting part (40a, 40b), the plunger detecting part and the clamp detecting part, to produce detection information therefrom, and is inputted with the detection information; wherein the control unit is configured to perform a control, based on the detection information, for displaying guidance in a character information display section and/or graphic display section showing respective changes between the states of the syringe pump before and after the operation of mounting the outer cylinder onto the syringe mounting part, the operation of holding the plunger by the slider and the operation of fixing the outer cylinder by the clamp.
