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;

a piston unit that pushes out a pharmaceutical from the preparation syringe mounted to the mounting portion;

an injection driver that drives the piston unit;

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

a read driving section that drives the preparation syringe 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 a 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, 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.

4. The pharmaceutical injection device according to claim 3,

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

5. The pharmaceutical injection device according to claim 1,

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

6. The pharmaceutical injection device according to claim 1,

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

7. The pharmaceutical injection device according to claim 2, further comprising two photosensors which detect two positions of the mounting portion in the axial direction, respectively,

wherein the first read driving section moves the mounting portion for moving the preparation syringe mounted to the mounting portion,

and wherein the reading section reads the identification code while the mounting portion is reciprocated between the two positions by the first read driving section.

8. The pharmaceutical injection device according to claim 2, further comprising a driving section which drives the mounting portion for inserting an injection needle,

wherein the preparation syringe is configured such that the injection needle injecting the pharmaceutical in the preparation syringe is attached thereto,

wherein the first read driving section moves the mounting portion for moving the preparation syringe mounted to the mounting portion,

and wherein the driving section serves as the first read driving section.

9. The pharmaceutical injection device according to claim 3,

wherein the reading section is configured to turn between a first position and a second position, to read the identification code provided on the preparation syringe in the first position, and to read an identification code placed outside the main body case through the opening in the second position.
