[Prior art]
2. Description of the Related Art Conventionally, in an automatic analyzer, a plurality of reagent containers containing reagents are generally arranged and stored in a circumferential shape on a mounting table rotatably provided in a reagent storage. . If dispensing of reagents is necessary, rotate the mounting table and move the reagent container to the dispensing point, then lower the reagent probe into the reagent container and aspirate the required amount of reagent. Is configured. When the reagent storage is stored with the reagent container kept open, it is generally kept cool at approximately 5 to 10 ° C. in order to prevent qualitative deterioration of the reagent.
[0003]
However, at low temperatures, the surroundings of the reagent container have a low humidity, so that there is a disadvantage that the reagent evaporates and its concentration changes. In addition, when a plurality of different reagents are installed in the reagent storage, there is a drawback in that, for example, an acid component in the reagent evaporates, altering other reagents, and causing rust inside the reagent storage.
[0004]
Further, the upper opening for the reagent may be sealed with an elastic film such as plastic or rubber, and when the reagent is sucked, the elastic film may be pierced with a reagent probe to perform suction. This is a so-called piercing dispensing. However, in this operation, although evaporation of the reagent can be prevented, a mechanical load is applied to the probe each time the reagent is aspirated. Therefore, it is necessary to strengthen the probe and make the reagent dispensing mechanism highly rigid. In addition, there is a possibility that fragments of the elastic film may reach the tip of the probe, which disturbs the dispensing accuracy.
[0005]
In view of such circumstances, a technique has been proposed in which a packing for preventing evaporation is attached to the cover of the reagent cool box (for example, see Patent Documents 1 and 2).

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of a reagent container and an automatic analyzer according to the present invention will be described in detail with reference to the drawings. It should be noted that the present invention is not limited by the embodiment.
[0015]
Embodiment 1 FIG.
FIG. 1 is a sectional view showing a reagent container and an automatic analyzer according to a first embodiment of the present invention, FIG. 2 is a sectional view showing a state in which a cap of the reagent container is opened by a guide pipe, and FIG. FIG. 4 is a plan view showing a cap of the container, and FIG. 4 is a cross-sectional view showing a cross section AA of the cap shown in FIG.
[0016]
As shown in FIGS. 1 to 4, the reagent container 1 includes a container body 2 having an opening 3 at an upper part, and a disc-shaped elastic member mounted on the opening 3 of the container body 2. And a cap 4 having four cap pieces 4b that can be elastically deformed by forming a cross-shaped notch 4a on the front side. The container body 2 is formed of, for example, polyethylene or polypropylene, and the cap 4 is formed of an elastic member such as rubber.
[0017]
That is, when no external force is applied to the cap 4, the reagent container 1 keeps the four cap pieces 4b closed (see FIG. 4) to prevent evaporation of the reagent solution in the container body 2 and will be described later. When the notch 4a of the cap 4 is pressed downward by the guide pipe 6, the four cap pieces 4b are elastically deformed downward and bent as the guide pipe 6 enters, so that an opening is formed in the reagent container 1. (See FIG. 2).
[0018]
Therefore, as shown in FIG. 2, the inside and the outside of the reagent container 1 communicate with each other through the opening 6a of the guide pipe 6, and the probe 30 and the cap 4 are inserted by inserting the probe 30 for aspirating the reagent through the opening 6a. The tip of the probe 30 can enter the reagent container 1 without contact with the (cap piece 4b).
[0019]
On the other hand, when the reagent suction by the probe 30 is completed and the probe 30 and the guide pipe 6 are raised, the cap piece 4b is released from the pressing force of the guide pipe 6, so that the cap piece 4b returns to the closed state before elastic deformation. Thus, evaporation of the reagent solution is prevented.
[0020]
Next, an automatic analyzer to which the reagent container 1 is applied will be described with reference to FIGS. As shown in FIG. 1, the automatic analyzer includes a mounting table 9 that is rotatably formed and mounts a plurality of reagent containers 1 in a circumferential arrangement, and a plurality of reagent containers mounted on the mounting table 9. Using a cooling means (not shown), the storage case 10 for storing the container 1 at a constant temperature (for example, keeping the temperature at 5 to 10 ° C.) and the cap 4 for closing the opening 3 of the reagent container 1 are selectively opened. A lid opening device 20, a position detection sensor (not shown) for detecting the position of the reagent container 1 placed on the mounting table 9, and a reagent detection sensor for detecting the type of reagent contained in the reagent container 1 (Not shown), receiving the signals from the sensors, rotating the mounting table 9 to position the desired reagent container 1 at the dispensing position, and then driving the lid opening device 20 to move the cap 4 And at the same time, lower the probe 30 in synchronization with this, And a control device for entering the drug container 1 (not shown).
[0021]
The storage case 10 includes a reagent storage 11 and a lid 12 having an opening 12a for inserting the probe 30. The mounting table 9 is connected to a shaft 14 rotatably supported by a bearing 13 and is formed to be rotatable. The shaft 14 has a gear 15 which meshes with a gear 17 connected to a motor 16. That is, the mounting table 9 is configured to rotate by a predetermined amount when the motor 16 operates according to a command from a control device (not shown) and the shaft 14 rotates via the gears 17 and 15.
[0022]
The lid opening device 20 provided in the storage case 10 opens the cap 4 of the reagent container 1, secures a space for the probe 30 to enter the reagent container 1, and prevents contact between the probe 30 and the cap 4.

It is composed of a rotary solenoid 23 that moves up and down through a shaft, and a guide 24 that guides the slide shaft 21.
[0023]
Next, the operation will be described. On the mounting table 9 of the automatic analyzer, a reagent container 1 containing reagents having different items is mounted for analyzing a plurality of types of analysis items. A command is issued by a control device (not shown) to drive the motor 16 and rotate the shaft 14 via the gears 17 and 15 so that the reagent container 1 corresponding to the selected analysis item is disposed immediately below the probe 30. Then, the mounting table 9 is rotated by a predetermined amount.
[0024]
That is, when the selected reagent container 1 is disposed immediately below the probe 30, the operation of the motor 16 is stopped, and the solenoid 23 is energized to lower the slide shaft 21 and the arm 5. The notch 4a of the cap 4 of the container 1 is pressed downward. As a result, the four cap pieces 4b are elastically deformed downward and bent as the guide pipe 6 enters, and an opening is formed in the reagent container 1. Therefore, the inside and outside of the reagent container 1 are opened through the opening 6a of the guide pipe 6. Communicate.
[0025]
Next, the probe 30 is lowered by a driving device (not shown) and inserted through the guide pipe 6 to enter the inside of the reagent container 1 to aspirate the reagent. At this time, a space for the probe 30 to enter the reagent container 1 is secured by the guide pipe 6, so that the probe 30 does not come into contact with the cap 4 (cap piece 4b).
[0026]
Therefore, the probe 30 to be washed before sucking the next reagent only needs to be immersed in the reagent, so that the washing is easy, the washing solution can be saved, and the waste liquid generated by washing can be reduced. Further, there is no influence of the occurrence of carryover, and there is no possibility of diluting the reagent liquid by bringing in the cleaning liquid attached to the probe 30.
[0027]
Then, the probe 30 having completed the suction operation is lifted by a driving device (not shown). At the same time, the solenoid 23 is energized to raise the slide shaft 21 and the arm 5 and raise the guide pipe 6 by a predetermined amount. Then, since the lower end of the guide pipe 6 moves away from the cap 4, the elastically deformed cap piece 4b is released from the pressing force of the guide pipe 6, and returns to the closed state before the elastic deformation.
[0028]
That is, the opening 3 of the reagent container 1 is closed again by the cap 4, and the evaporation of the reagent in the reagent container 1 is prevented. The reagent aspirated by the probe 30 is discharged to a reaction vessel (not shown) and analyzed. By repeating such an operation, continuous analysis can be performed for a plurality of types of analysis items.
[0029]
As described above, since the reagent container 1 and the automatic analyzer according to the first embodiment have a simple configuration, they can be manufactured easily and inexpensively, and the opening 3 of the reagent container 1 As a result, the reagent is securely closed, so that evaporation and deterioration of the reagent can be prevented. In addition, since the cap 4 is provided for each reagent container 1, the occurrence of contamination can be prevented.
[0030]
In addition, the automatic analyzer is configured so that the advancing / retreating operation of the probe 30 and the opening / closing operation of the cap 4 at the time of aspirating the reagent are synchronized, so that the reagent analysis of multiple items can be performed efficiently. Further, since the lid opening device 20 has a simple configuration in which the solenoid 23, the slide shaft 21, the arm 5, the guide pipe 6, and the like are combined, it can be manufactured easily and inexpensively.
[0031]
In the first embodiment, the solenoid 23 is used as a driving unit for the slide shaft 21 and the like. However, the present invention is not limited to this. For example, the solenoid may be driven by a motor. Further, the shape of the reagent container 1 is not limited to the illustrated example (cylindrical shape), but may be a rectangular parallelepiped or the like.
[0032]
Also, the cut 4a of the cap 4 has been described as being formed in a cross shape, but is not limited to this, and it is sufficient if there is at least one cut, and the opening of the cap 4 is appropriate when the guide pipe 6 enters. Any shape may be used as long as the shape can be formed.

This is to secure a space for entry into the inside and to prevent contact between the probe 30 and the cap 4. The guide pipe 8 has a double pipe structure including an inner pipe portion 8a and an outer pipe portion 8b shorter than the inner pipe portion 8a, and both are connected by a ceiling surface 8d having an opening 8c. .
[0036]
As shown in FIG. 6, the length of the outer pipe portion 8b is such that the guide pipe 8 is pressed by a pressing arm 35 described later, and the ceiling surface 8d of the guide pipe 8 and the ceiling surface 7c of the reagent container lid 7 are flush.

When they become one, the guide pipe 8 is set to such an extent that the cap piece 4b can be completely pushed and spread. That is, the tip of the cap piece 4b is not exposed to the inside of the opening 8c of the guide pipe 8 to prevent contact between the cap piece 4b and the probe 30 when the probe 30 enters.
[0037]

The inner diameter of the washer hole 33a is formed to be slightly larger than the outer diameter of the inner pipe portion 8a, and the inner pipe portion 8a is formed so as to be insertable, and the lower end of the compression coil spring 32 is formed at the outer peripheral edge of the washer hole 33a. It is formed so that the part can be locked.
[0039]
Next, the automatic analyzer will be described. The difference from the configuration of the first embodiment shown in FIG. 1 is that, as shown in FIGS. 7 and 8, a pressing arm 35 for pressing the guide pipe 8 is provided at the lower end of the slide shaft 21. It is a point. An opening 35 a for inserting the probe 30 is provided on the pressing arm 35 so as to be coaxial with the opening 12 a of the lid 12 and the opening 8 c of the guide pipe 8. Other configurations are the same as those described in the first embodiment, and thus redundant description will be omitted.
[0040]
Next, the operation will be described mainly with reference to FIG. On the mounting table 9 of the automatic analyzer, a reagent container 1 containing reagents having different items is mounted for analyzing a plurality of types of analysis items. A command is issued by a control device (not shown) to drive the motor 16 and rotate the shaft 14 via the gears 17 and 15 so that the reagent container 1 corresponding to the selected analysis item is disposed immediately below the probe 30. Then, the mounting table 9 is rotated by a predetermined amount.
[0041]
That is, when the selected reagent container 1 is disposed immediately below the probe 30, the operation of the motor 16 is stopped, and the solenoid 23 is energized to lower the slide shaft 21 and the pressing arm 35. The ceiling surface 8d of the guide pipe 8 of the reagent container 1 is pressed.
[0042]
Then, as shown in FIGS. 6 and 7, the compression coil spring 32 of the guide pipe 8 is compressed by this pressing force, and the guide pipe 8 is pushed down. Press down. As described above, the four cap pieces 4b are elastically deformed downward and bent as the guide pipe 8 enters, and an opening is formed in the reagent container 1. Therefore, the inside and outside of the reagent container 1 are opened through the opening 8c of the guide pipe 8. Communicate.
[0043]
Next, the probe 30 is lowered by a driving device (not shown) and inserted through the guide pipe 8 to enter the inside of the reagent container 1 to aspirate the reagent. At this time, a space for the probe 30 to enter the reagent container 1 is secured by the guide pipe 8, so that the probe 30 does not come into contact with the cap 4 (cap piece 4b).
[0044]
Therefore, the probe 30 to be washed before sucking the next reagent only needs to be immersed in the reagent, so that the washing is easy, the washing solution can be saved, and the waste liquid generated by washing can be reduced. Further, there is no influence of the occurrence of carryover, and there is no possibility of diluting the reagent liquid by bringing in the cleaning liquid attached to the probe 30.
[0045]
Then, the probe 30 having completed the suction operation is lifted by a driving device (not shown). At the same time, the solenoid 23 is energized to raise the slide shaft 21 and the pressing arm 35. Then, since the guide pipe 8 is released from the pressing force of the pressing arm 35, it is lifted by the urging force of the compression coil spring 32, and returns to the position shown in FIG. At the same time, since the lower end of the guide pipe 8 moves away from the cap 4, the elastically deformed cap piece 4b is released from the pressing force of the guide pipe 8, and returns to the closed state before the elastic deformation (FIG. 5).
[0046]
That is, the opening 3 of the reagent container 1 is closed again by the cap 4, and the evaporation of the reagent in the reagent container 1 is prevented.

Data can be obtained.
[0048]
As described above, since the reagent container 1 and the automatic analyzer according to the second embodiment have a simple configuration, they can be manufactured easily and inexpensively, and the opening 3 of the reagent container 1 As a result, the reagent can be reliably blocked, so that evaporation and deterioration of the reagent can be prevented.
