Abstract
Official abstract text for this publication.
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 ).
First claim
Opening claim text (preview).
The invention claimed is: 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, the drive mechanism including a piston drive motor 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 from the amount of movement of the piston, wherein, when the presence of a pharmaceutical is detected by the remaining pharmaceutical sensor, the controller causes the display section to display a warning that includes an express instruction that the pharmaceutical syringe be removed from the pharmaceutical syringe mounting portion and that the pharmaceutical syringe be stored in a refrigerator. 2. The pharmaceutical injection device according to claim 1 , wherein the controller turns off power of the device after the pharmaceutical syringe has been removed from the pharmaceutical syringe mounting portion following the display of a warning on the display section.
