Problems solved by technology

[0010] However, such a conventional preparation injection system has a problem that it is difficult for the user to discriminate the preparation by simply looking at the preparation syringe because the identification is performed by the barcode.
[0011] In addition, in the above case, since the identification of the barcode and the attachment of the preparation syringe to the liquid medicine injector are not performed at the same time, there is a possibility that the user mistakenly attaches a medicine syringe different from the barcode to the liquid medicine injection device. risk of administering the wrong formulation
In addition, there is a problem that a code reader is required on the side of the liquid medicine injection device, so it is large in size, poor in portability, and expensive.

Embodiment approach 1

[0089] image 3 It is an overall perspective view of the drug injection device according to Embodiment 1 of the present invention.

[0090] Such as image 3 As shown, the structure of the drug injection device 1 includes: a housing 2, a front end cap 3, a confirmation window 4, a syringe cover 5, and a detection protrusion 5b (refer to Figure 4 ), a power button 6, an exhaust button 7, an end button 8, a drug injection button 9, and an LCD (Liquid Crystal Display) 10 as a display unit.

[0091] The drug administration device 1 is covered by a casing 2 which is an outer casing of the device main body.

[0092] The front end cap 3 can be detachably attached to one end of the housing 2, and the front end cap 3 can be detached as required when installing / detaching the preparation syringe 11 or the injection needle for injecting the medicinal solution.

[0093] The front end cap 3 has a confirmation window 4 for internal confirmation, so that the preparation syringe 11 can be v...

Embodiment approach 2

[0156] Embodiment 2 is an example in which a transmissive color detection unit is applied to a color detection unit.

[0157] Figure 10 and Figure 11 It is a sectional view showing the states before and after the preparation syringe 42 of the drug injection device according to Embodiment 2 of the present invention is mounted in the drug injection device 1 . Figure 10 is an internal cross-sectional view showing the state before the preparation syringe 42 is installed in the syringe holder 50, Figure 11 It is an internal cross-sectional view showing a state after the preparation syringe 42 is mounted in the syringe holder 50 . right with Figure 4 and Figure 5 The same structural parts are given the same reference numerals, and descriptions of overlapping parts are omitted.

[0158] Such as Figure 10 and Figure 11 As shown, the syringe cover 41 is used for transmission color detection and has a first opening 41a and a second opening 41b. In addition, a part or the...

Embodiment approach 3

[0170] Embodiment 3 is an example in which the features of the reflective color detection unit in Embodiment 1 are effectively utilized, and a plurality of color detection units are further provided.

[0171] Figure 13 and Figure 14 It is a sectional view showing the states before and after the preparation syringe 46 of the drug injection device according to Embodiment 3 of the present invention is installed in the drug injection device 1 . Figure 13 is an internal cross-sectional view showing the state before the preparation syringe 46 is installed in the syringe holder 50, Figure 14 is an internal cross-sectional view showing the state after the preparation syringe 46 is installed in the syringe holder 50. Figure 4 and Figure 5 The same structural parts are given the same reference numerals, and descriptions of overlapping parts are omitted.

[0172] Such as Figure 13 and Figure 14 As shown, the drug injection device 1 has a first color detection unit 47 and a ...

Abstract

A medication administering device for automatically identifying a medication syringe and administering a correct medication. A microprocessor (20) of the medication administering device (1) identifies the color of a medication or a medication syringe on the basis of a reference value, determines the adequateness of the medication, and indicates the result of the determination by means of an LCD (10) or the like to the user. In step S4, the microprocessor (20) determines whether or not color data received from a color detecting unit (13) is within a reference value range. If the color data is within the reference value range, the microprocessor proceeds to step S5, otherwise proceeds to step S6. In step S6, the microprocessor (20) issues a message to the effect that the user needs to check the medication.

Description

technical field [0001] The present invention relates to a drug injection device capable of administering a drug to a living body and the like by attaching a drug syringe filled with a drug. Background technique [0002] When administering the drug solution in the preparation syringe to the tester, the operator prepares a preparation syringe of an appropriate drug. In response to predetermined operations, the drug injection device relatively moves the piston member and the syringe member by the injection actuator, and administers the drug solution to the subject from the drug solution syringe. [0003] In the conventional drug injection device, the bar code printed on the packaging material attached to the drug or the bar code attached to the drug syringe can be read by a barcode reader mounted on the drug injection device, and the result can be displayed on the display. In part, the operator can easily and reliably confirm the preparation, and a drug injection system includ...
