Abstract

The pharmaceutical injection device of the present invention comprises an inner case (111) in which is mounted a preparation syringe (104) having an identification code (104a), a piston driving motor (115) that drives the preparation syringe (104) mounted in this inner case (111), and a code reader (112) that reads the identification code (104a) of the preparation syringe (104). A slide motor (113) is provided that drives the preparation syringe (104) mounted in the inner case (111) and/or the code reader (112), so that the identification code (104a) is read by the code reader (112).

Claims

1. A pharmaceutical injection device, comprising:

a mounting portion to which is mounted a preparation syringe having an identification code;

an injection driver that drives a preparation syringe mounted to the mounting portion;

reading section that reads an identification code on the preparation syringe; and

read driving section that drives the preparation syringe mounted to the mounting portion and/or the reading section, so that the identification code is read by the reading section.

2. The pharmaceutical injection device according to claim 1,

wherein the read driving section has first read driving section that moves the preparation syringe mounted to the mounting portion in the axial direction of the preparation syringe.

3. The pharmaceutical injection device according to claim 1,

wherein the read driving section has second read driving section that moves the preparation syringe mounted to the mounting portion in the peripheral direction of the preparation syringe.

4. The pharmaceutical injection device according to claim 1,

wherein the read driving section has a variable driver that changes the movement speed at which the preparation syringe is moved.

5. The pharmaceutical injection device according to claim 1,

further comprising:

a main body case that houses in its interior the mounting portion, the injection driver, the reading section, and the read driving section; and

an opening for the reading section, which is provided to the main body case.

6. The pharmaceutical injection device according to claim 5,

further comprising a reflecting plate that is provided inside the main body case and optically couples the reading section and the opening.

7. The pharmaceutical injection device according to claim 5,

further comprising a transparent plate that is mounted in the opening.

8. The pharmaceutical injection device according to claim 1,

wherein the read driving section has position detector that detect the position of the identification code.

9. The pharmaceutical injection device according to claim 1,

further comprising notification section connected to the reading section, that conveys a reading result.

10. The pharmaceutical injection device according to claim 1,

wherein the read driving section moves the preparation syringe in the axial direction, and also moves the preparation syringe again in the axial direction after the identification code has been read by the reading section.

11. The pharmaceutical injection device according to claim 10,

wherein the read driving section moves the preparation syringe to its initial position as a position before reading after the identification code has been read, and then moves the preparation syringe again in the axial direction.

12. The pharmaceutical injection device according to claim 11,

wherein the read driving section moves the preparation syringe to its initial position after the identification code has been read, and then moves the preparation syringe again in a puncture direction.
