Abstract

This pharmaceutical injection device comprises a main body case (2) that has an injection needle insertion and retraction opening (1); pharmaceutical syringe mounting portion (3) that is provided within the main body case (2); a piston (5) that is provided movably with respect to a pharmaceutical syringe (4) that is mounted to the pharmaceutical syringe mounting portion (3); a drive mechanism (6) that drives the piston (5); a controller (7) that is electrically connected to the drive mechanism (6); and a display section (35) that is electrically connected to the controller (7). The controller (7) updates the display content that is displayed on the display section (35) according to the number of times the drive mechanism (6) has been driven, and saves this updated display content in a memory (51), so that when the drive mechanism (6) has been driven a specific number of times, the display contents during the various instances of drive that were saved in the memory (51) are combined.

Claims

1. A pharmaceutical injection device, comprising:

a main body case that has an injection needle insertion and retraction opening;

a pharmaceutical syringe mounting portion that is provided within the main body case;

a piston that is provided movably with respect to a 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; and

a display section that is electrically connected to the controller,

wherein the controller updates the display content displayed on the display section according to the number of times the drive mechanism has been driven, and saves the updated display content in a memory, so that when the number of times the drive mechanism has been driven reaches a specific number, the display contents during the various instances of drive that were saved in the memory are combined.

2. The pharmaceutical injection device according to claim 1,

wherein, when the number of times the drive mechanism has been driven reaches a specific number, the controller combines the display contents for the various instances of drive that were saved in the memory, to give a finished product display.

3. The pharmaceutical injection device according to claim 1,

wherein, when the drive mechanism is driven again within a specific length of time, the controller puts the display content displayed on the display section in a non-updated state.

4. The pharmaceutical injection device according to claim 3,

wherein, when the drive mechanism is driven again within a specific length of time, the controller displays the display content from the previous update.

5. The pharmaceutical injection device according to claim 1,

wherein, when the number of times the drive mechanism has been driven within a specific length of time does not reach a specific number, the controller causes the display section to display a message to the effect that a finished product display in which the display contents for the various instances of drive are combined cannot be given.

6. The pharmaceutical injection device according to claim 5,

wherein, when the number of times the drive mechanism has been driven within a specific length of time does not reach a specific number, the controller deletes the display content saved in the memory.

7. The pharmaceutical injection device according claim 1,

wherein the controller saves in the memory a finished product display obtained by combining the display contents for the various instances of drive.

8. The pharmaceutical injection device according to claim 7,

wherein the controller selectively displays the finished product display saved in the memory, and the display content from the last update.
