Description

[Detailed Description of the Invention] This invention relates to an automatic analyzer, and more particularly to an automatic analyzer that can easily confirm the amount of liquid in a reagent container containing a predetermined amount of a reagent corresponding to an analysis item.

As is well known, when various reagents corresponding to analysis items are arranged in an automatic analyzer for blood, etc., and a predetermined amount of these reagents is automatically dispensed to a specimen, etc., the remaining amount of reagents in the reagent container is checked at any time. Confirmation is important for analysis accuracy control.

This invention aims to provide an automatic analyzer suitable for extremely easily confirming the amount of remaining liquid of a reagent.

In order to achieve this object, in this invention, a movable reagent liquid amount confirmation device is disposed along the protrusion communicating with the hollow portion of the reagent container.

Hereinafter, this invention will be explained in detail based on an embodiment shown in the accompanying drawings.

The reagent container B according to this example is shown in FIGS. 1 and 2.
As shown in the figure, the container body 1 is made of a chemical-resistant material with excellent translucency and is formed into a hollow box shape, and the upper surface 2 thereof has two reagent injection ports 4 that communicate with the hollow part of the container body 1. has been done. This reagent inlet 4 is covered with a cap 5. Further, a protruding portion 7 of a convex strip communicating with the hollow portion 3 of the container body 1 is formed on the front surface 6 of the container body 1, and the protruding portion 7 is particularly designed for the container as shown in FIG. It is provided so as to protrude in the height direction of the main body 1 so as to have a convex strip shape.

Therefore, when the reagent S corresponding to the analysis item is sealed in the reagent container B, the reagent S also fills the protrusion 7 communicating with the hollow part 3 of the reagent container B, and the reagent S in the protrusion 7 The liquid level of S is accommodated so as to be on the same plane as the liquid level in the hollow part of the container body 1.

Next, a case where the remaining amount of the reagent S is confirmed using the reagent container B according to the above embodiment will be explained based on FIG. 3.

The reagent container B attached to a reagent placement section (not shown) of the automatic analyzer is disposed with its front surface 6 facing the liquid amount confirmation device 10. This liquid level confirmation device 10 includes a bracket 12 having a recess 11 formed in a portion facing the front surface 6 of a reagent container B, a light irradiator 13 disposed on a surface opposite to the recess 11, and a It consists of a photoreceptor 14 and a control device 15 that detects the rotation angle of the motor M that controls the movement of the bracket 12 based on the data received by the photoreceptor 14. The above-mentioned bracket 12 is configured to slide from top to bottom along the length direction of the protrusion 7 by a motor M, and when the vertical sliding of this bracket 12 is started, the light irradiation body Infrared light is emitted from 13, passes through the protrusion 7, and enters the photoreceptor 14.
Then, the photoreceptor 14 converts this amount of transmitted light into a voltage. In other words, as shown in FIG.
Since the amount of light entering the photoreceptor 14 decreases, and as a result, the voltage V rapidly decreases, the control device 15 detects the rotation angle of the motor M at the time when the voltage suddenly decreases, In this way, the remaining amount of the reagent S can be confirmed by calculating and detecting the descending distance of the bracket 12.

As shown in the above embodiment, the protrusion 7 is made of a material with excellent translucency, like the container body 1, but only the protrusion 7 is made of a material with excellent translucency. The protruding portion 7 may be formed of any material, and it is desirable that the protruding portion 7 be formed to be as narrow as possible in order to prevent light dispersion and ensure sufficient translucency.

Furthermore, in the above embodiment, the case where the protruding part 7 is disposed on the front surface 6 of the container body 1 has been explained as an example, but this invention is not limited to this, and for example, the protruding part 7 can be disposed on the rear surface or other parts. In short, it is sufficient that it is formed at a portion facing the liquid amount confirmation device 10.

As explained above, this invention can provide an automatic analyzer that can easily confirm the remaining amount of reagent.
