PHARMACEUTICAL INJECTION DEVICE
First Claim
1. A pharmaceutical injection device, comprising:
- a main body case that has an opening through which an injection needle is inserted and retracted;
a pharmaceutical syringe mounting portion that is provided inside the main body case and to which a pharmaceutical syringe is removably mounted;
a piston that is provided movably with respect to the pharmaceutical syringe mounted to the pharmaceutical syringe mounting portion;
a drive mechanism configured to drive the piston;
a controller that is electrically connected to the drive mechanism;
a display section that is connected to the controller; and
a remaining pharmaceutical sensor that is connected to the controller and configured to sense the amount of pharmaceutical remaining in the pharmaceutical syringe,wherein, if the presence of a pharmaceutical is detected by the remaining pharmaceutical sensor, the controller causes the display section to display a warning recommending removal of the pharmaceutical syringe from the pharmaceutical syringe mounting portion.

Abstract
The pharmaceutical injection device includes a pharmaceutical syringe mounting portion (3) provided within a main body case (2) and to which a pharmaceutical syringe (4) is removably mounted, a piston (5) provided movably with respect to the pharmaceutical syringe (4) mounted to the pharmaceutical syringe mounting portion (3), a drive mechanism (6) for driving the piston (5), a controller (7) that is electrically connected to the drive mechanism (6), a display section (35) that is connected to the controller (7), and an encoder (26) that is connected to the controller (7) and detects the amount of the pharmaceutical remaining inside the pharmaceutical syringe (4). The controller (7) displays a warning on the display section (35) recommending removal of the pharmaceutical syringe (4) from the pharmaceutical syringe mounting portion (3) when the presence of a pharmaceutical is detected by the encoder (26).
