Abstract

A pharmaceutical injection device comprises a main body case (2); a pharmaceutical syringe mounting component (3) that is provided inside the main body case (2) and onto which a pharmaceutical syringe (4) is mounted; a piston (5) provided movably with respect to the pharmaceutical syringe (4) mounted onto the pharmaceutical syringe mounting component (3); a drive mechanism (6) for driving the piston (5); a memory (46) that stores a preset pharmaceutical injection schedule; and a controller (7) that resets a current pharmaceutical dose by comparing a planned cumulative pharmaceutical dose, which is a planned cumulative amount of pharmaceutical injected up to the last time on the basis of the pharmaceutical injection schedule stored in the memory, and an actual cumulative pharmaceutical dose, which is a cumulative amount of pharmaceutical actually injected up to the last time.

Claims

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 component that is provided inside the main body case and onto which a pharmaceutical syringe is mounted;

a piston that is provided movably with respect to the pharmaceutical syringe mounted onto the pharmaceutical syringe mounting component;

a drive mechanism that drives the piston;

a display component that displays information related to the injection of a pharmaceutical;

a memory that is provided inside the main body case and stores a preset pharmaceutical injection schedule; and

a controller that is electrically connected to the drive mechanism, the display component, and the memory, and resets a current pharmaceutical dose by comparing a planned cumulative pharmaceutical dose, which is a planned cumulative amount of pharmaceutical injected up to the last time on the basis of the pharmaceutical injection schedule stored in the memory, with an actual cumulative pharmaceutical dose, which is a cumulative amount of pharmaceutical actually injected up to the last time.

2. The pharmaceutical injection device according to claim 1, wherein the controller resets a future pharmaceutical injection schedule, including a current pharmaceutical dose.

3. The pharmaceutical injection device according to claim 2, wherein the controller stores the reset future pharmaceutical injection schedule in the memory, and holds the preset pharmaceutical injection schedule.

4. The pharmaceutical injection device according to claim 3, wherein, if the reset future pharmaceutical injection schedule has been further reset, the controller updates the reset pharmaceutical injection schedule stored in the memory to the further reset pharmaceutical injection schedule.

5. The pharmaceutical injection device according to claim 2, wherein the controller causes the display component to display the current planned pharmaceutical dose that is planned on the basis of the reset future pharmaceutical injection schedule.

6. The pharmaceutical injection device according to claim 5, wherein the controller causes the display component to display whether the actual pharmaceutical dose produced by comparing the cumulative planned pharmaceutical dose up to the last time with the actual pharmaceutical dose up to the last time is too high or too low.

7. The pharmaceutical injection device according to claim 6, wherein the controller causes the display component to display the excess amount or the deficient amount of the actual cumulative pharmaceutical dose produced by comparing the cumulative planned pharmaceutical dose up to the last time with the actual cumulative pharmaceutical dose up to the last time.

8. The pharmaceutical injection device according to claim 7, wherein the controller causes the display component to display the reason why the actual cumulative pharmaceutical dose produced by comparing the cumulative planned pharmaceutical dose up to the last time with the actual cumulative pharmaceutical dose up to the last time is too high or too low.

9. The pharmaceutical injection device according to claim 6, wherein the controller causes the display component to display a message prompting the user to consult a physician when the excess amount or the deficient amount of the actual cumulative pharmaceutical dose produced by comparing the cumulative planned pharmaceutical dose up to the last time with the actual cumulative pharmaceutical dose up to the last time has exceeded a specific value.

10. A method for controlling a pharmaceutical injection device comprising a main body case that has an opening through which an injection needle is inserted and refracted;

a pharmaceutical syringe mounting component that is provided inside the main body case and onto which a pharmaceutical syringe is mounted;

a piston that is provided movably with respect to the pharmaceutical syringe mounted onto the pharmaceutical syringe mounting component;

a drive mechanism that drives the piston;

a display component that displays information related to the injection of a pharmaceutical; and

a memory that is provided inside the main body case and stores a preset pharmaceutical injection schedule;

wherein said method includes a resetting step of resetting a future pharmaceutical injection schedule by comparing a cumulative planned pharmaceutical dose, which is a planned cumulative amount of pharmaceutical injected up to the last time on the basis of a pharmaceutical injection schedule stored in the memory, and a actual cumulative pharmaceutical dose, which is a cumulative amount of pharmaceutical actually injected up to the last time.

11. Non-transitory computer readable medium comprising:

a program for causing a computer to execute the resetting step of the method for controlling a pharmaceutical injection device according to claim 10.

12. (canceled)
