Description

The present invention relates to an automatic analyzer for analyzing samples such as blood and urine, and a reagent storage cabinet.

Patent document 1 describes an automatic analyzer that is configured to be able to use reagent containers that have an ID such as a barcode attached to the top or bottom, or both, of the reagent container.

JP 2008-157970 A

For reagents used in automated analyzers that analyze samples, information such as the type of reagent is recorded on an information recording medium such as a barcode, and this information is read and used for quality control of the tests.

When an operator needs to input the type of reagent into a computer, there is a risk that incorrect analysis results will be reported if the operator inputs the information incorrectly or places the reagent container in the wrong position when installing it. To solve these problems, there is technology that allows the device to automatically identify the type of reagent by reading a recording medium (see, for example, Patent Document 1).

In recent years, the location where the information recording medium is attached is not limited to the top or side of the reagent container, but is also sometimes attached to the bottom. However, in the method described in Patent Document 1, it is considered preferable that the information recording medium is provided on the top surface of the reagent container, and it is difficult to read information recording media provided on the side or bottom of the reagent container.

The object of the present invention is to provide an automatic analyzer that can use reagent containers without distinguishing between those that have an information recording medium on the side or bottom for identifying the reagent, and that can perform tests using more correct reagents than conventional methods, and a reagent storage unit that realizes this.

The present invention includes multiple means for solving the above problems, and one example is a reagent storage cabinet comprising a reagent disk on which multiple reagent containers are placed, each of which holds a reagent therein and has an identification code on which information about the reagent is recorded, a main body for housing the reagent disk, a lid for the reagent disk that covers the top side of the main body, a rotating mechanism for rotating the reagent disk, and a reading device for reading the identification code, the cabinet being characterized by comprising a guide for moving the reading device between the side and bottom of the reagent containers placed on the reagent disk.

According to the present invention, reagent containers with information recording media on the side or bottom can be used without distinction, and tests can be performed using more accurate reagents than in the past. Problems, configurations, and effects other than those described above will become clear from the explanation of the following examples.

Below, examples of the reagent storage and automatic analyzer of the present invention are described with reference to the drawings. In the drawings used in this specification, identical or corresponding components are given the same or similar reference numerals, and repeated explanations of these components may be omitted.

Example 1
A reagent storage and an automatic analyzer according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 7. FIG.

First, the overall configuration of the automatic analyzer will be described with reference to Figure 1. Figure 1 is a diagram showing the schematic configuration of the automatic analyzer according to the first embodiment.

In FIG. 1, the automatic analyzer 100 is an apparatus for dispensing a sample and a reagent into a reaction section 105, and measuring the physical properties of the mixture prepared by reacting them, and is equipped with a sample installation section 103, a dispensing system 28, a reagent storage cabinet 1, the reaction section 105, a detection section 106, a control section 107, an operation section 108, etc.

The specimen mounting section 103 is structured to mount specimen containers (not shown for convenience) in a ring shape. When dispensing a specimen, the specimen mounting section 103 rotates and transports the specimen container to an access position of the dispensing system 28.

The reagent storage facility 1 is a mechanism for storing reagent containers 14 (see Figures 2 and 3) containing reagents, and has a reagent disk 13, etc.

The reagent disk 13 has multiple reagent placement positions, and is configured to allow placement of multiple reagent containers 14. The reagent disk 13 has a rotation drive mechanism, and the rotational motion moves each reagent container 14 to a predetermined position on the circumference.

The dispensing system 28 is composed of a rotation drive mechanism, a vertical drive mechanism, and a dispensing probe, and is moved by the rotation drive mechanism and the vertical drive mechanism between the sample suction position of the sample mounting section 103 and the sample discharge position of the reaction section 105, or between the reagent suction position (position of the dispensing hole 4) of the reagent storage 1 and the reagent discharge position of the reaction section 105, to dispense samples from sample containers or reagents from reagent containers 14. This dispensing system 28 may be in a form in which a system dedicated to samples and a system dedicated to reagents are provided separately, or in a form in which they are shared, and is not particularly limited.

The control unit 107 is composed of, for example, a hardware board and a computer, and has a built-in storage device such as a hard disk. In this embodiment, the control unit 107 controls the operation of the reading device 16 so that the reading device 16 reads the identification code 15 when the dispensing system 28 dispenses a reagent. Details will be described later.

The control unit 107 may be configured as hardware using a dedicated circuit board, or may be configured as software executed by a computer. When configured as hardware, it can be realized by integrating multiple arithmetic units that execute the processing on a wiring board, or in a semiconductor chip or package. When configured as software, it can be realized by equipping the computer with a high-speed general-purpose CPU and executing a program that executes the desired arithmetic processing. It is also possible to upgrade existing devices using a recording medium on which this program is recorded. Furthermore, these devices, circuits, and computers are connected by a wired or wireless network, and data is sent and received as appropriate.

The operation unit 108 is composed of a display device, such as a display, and input devices such as a mouse and a keyboard.

Next, the configuration of the reagent container 14 preferably used in the automated analyzer 100 of this embodiment will be described with reference to Figures 2 and 3. Figure 2 shows the identification code on the side of the reagent container, and Figure 3 shows the identification code on the bottom of the reagent container.

The reagent containers 14 shown in Figures 2 and 3 are each a container with a tubular side, hold a reagent therein, and have an identification code 15 in which information about the reagent is recorded.

The reagent container 14 shown in Figure 2 has an identification code 15, which may be a two-dimensional barcode, a one-dimensional barcode, or the like, attached to its side. The identification code 15 stores a container ID for identifying the reagent container 14, the type of reagent, the amount of reagent, the expiration date of the reagent, and other necessary information.

The reagent container 14 shown in Figure 3 has an identification code 15, such as a two-dimensional barcode or a one-dimensional barcode, attached to its bottom surface.

In this embodiment, the reagent container 14 is described as having a tube shape as shown in Figures 2 and 3, but the shape is not particularly limited and may be a rectangular parallelepiped shape, etc. Also, the container may have two or more separated compartments so that one container can hold two or more types of reagents.

Next, the details of the structure of the reagent storage 1 of the automatic analyzer 100 of the present invention will be described with reference to Figures 4 to 6. Figure 4 is a diagram showing the schematic configuration of the reagent storage of the automatic analyzer of Example 1, Figure 5 is a diagram showing the schematic cross-sectional configuration of the reagent storage, and Figure 6 is a diagram showing the details of the curved guide, block, and reading device in the reagent storage.

As shown in Figures 4 and 5, the reagent storage cabinet 1 is composed of a reagent disk 13, a main body 3, a lid 2, a fixing device 5, a kettle 6, an insulating material 7, windows 9, 10, a rotation mechanism, a reading device 16, a curved guide 19, a block 17, a timing belt 20, a timing pulley 21, an idler pulley 22, etc.

The main body 3 is a container that houses the reagent disk 13 inside, and has an insulating material 7 that houses the kettle 6 interposed between the main body 3 and the reagent disk 13, and one or more windows 9 made of transparent material on the side and one or more windows 10 on the bottom for reading the identification code 15.

Window 10 is provided in the bottom surface of the substantially disk-shaped main body 3 in an area directly below the location of dispensing hole 4 in lid 2, by removing a portion of main body 3 and insulating material 7. Window 9 is provided in the side surface of the substantially disk-shaped main body 3 in an area toward the circumferential outer periphery of reagent disk 13, where dispensing hole 4 in lid 2 is provided, by removing a portion of main body 3 and insulating material 7.

These windows 9, 10 are provided in one location each on the side or bottom surface of the main body 3, but two or more locations each on the side or bottom surface may also be provided.

The reader 16 is a device that reads the identification code 15, and is installed on the curved guide 19 so as to read the identification code 15 placed on the reagent disk 13 through the windows 9 and 10. The reader 16 is equipped with an imaging element such as a CMOS camera, but may also be one that oscillates a laser and reads the code using the light, and is not particularly limited.

The curved guide 19 shown in Figures 4 to 6 is provided on the outside of the main body 3 of the reagent storage cabinet 1, and is provided to move between a window 10 capable of capturing an image of the bottom surface of a reagent container 14 placed on the reagent disk 13, and a window 9 capable of capturing an image of the side surface of the reagent container 14. The movement of the reading device 16 between the window 9 and window 10 is controlled by the control unit 107.

This curved guide 19 is installed so as to trace a trajectory that aligns with the position at which the identification code 15 attached to the reagent container 14 installed inside can be seen from window 9 or window 10 of the reagent storage cabinet 1, and it is desirable that the reagent container 14 be installed so that the identification code 15 can be seen from window 9 if it is on the side, or from window 10 if it is on the bottom.

It is desirable that the curved guide 19 be arranged so as to connect windows 9 and 10 in a straight line when the automatic analyzer 100 is viewed from above in the vertical direction, and it is also desirable that the curved guide 19 be an arc-shaped motion guide that is curved when the reagent storage cabinet 1 is viewed from the vertical direction.

In the curved guide 19, a block 17 to which a reading device 16 is attached moves on the curved guide 19 which draws a curve. The block 17 can be moved by a timing belt 20. The timing belt 20 is moved by a timing pulley 21 and an idler pulley 22. In addition to the curved guide 19, the block 17 can be provided on a belt conveyor, and the reading device 16 can be attached to the block 17, allowing the reading device 16 to be moved.

In addition, the reading device 16 and the curved guide 19 are not limited to being placed outside the main body 3, but may also be installed inside the main body 3.

In addition, multiple reading devices 16 may be installed within the automatic analysis device 100, but it is preferable to have only one in the area close to the reagent storage room 1.

The lid 2 covers the top side of the main body 3 and is provided with a dispensing hole 4 that allows the dispensing system 28 to access the reagent container 14 installed on the reagent disk 13 inside the main body 3. The lid 2 is provided with a fixing device 5 that prevents the lid 2 from being freely opened after the reagent has been installed, and the fixing device can be opened and closed by a command from a device such as an electromagnetic lock.

The rotation mechanism rotates the reagent disk 13, and is composed of a motor 23, pulley 24, belt 25, shaft 26, base 27, etc. The shaft 26 is connected to the center of the reagent disk 13. The shaft 26 is rotated by the motor 23 via the pulley 24 and belt 25, making it possible to rotate the reagent disk 13. These components are held by the base 27. Note that the method of rotating the reagent disk 13 is not limited to this, and it may be rotated by other methods.

Next, the flow of reading the identification code 15 when reading reagent information in the automatic analyzer 100 of this embodiment will be explained using Figure 7. Figure 7 shows the reagent information reading workflow of the automatic analyzer of Example 1.

As shown in FIG. 7, when the introduction of a reagent container 14 into the device is started, for example, by manual introduction by an operator or automatic introduction by a reagent container transport device, reading of the identification code 15 is started (step 301).

First, the control unit 107 controls the rotation mechanism to rotate the reagent disk 13 so that the location where the reagent container 14 to be read is placed is directly below the dispensing hole 4, which is the first reading position, i.e., the position of the windows 9 and 10, and then stops the rotation (step 302). At the same time, the reading device 16 is moved to a position where it can capture an image of the reagent container 14 through the window 9 on the side of the main body 3 (step 302).

Then, the reader 16 reads the identification code 15 on the side of the reagent container 14 mounted on the reagent disk 13 through the window 9, and determines whether the identification code 15 is located on the side and whether the reading was successful (step 303). If the reading was successful, the process proceeds to step 306A.

On the other hand, if the reading fails, the process proceeds to step 304, and the reading device 16 is moved to a position where it can capture an image of the reagent container 14 through the window 10 on the bottom of the main body 3 (step 304).

Then, the reading device 16 reads the identification code 15 on the bottom surface of the reagent container 14 mounted on the reagent disk 13 through the window 10, and determines whether the identification code 15 is located at the bottom position and whether the reading was successful (step 305).

If the reading is successful, the process proceeds to step 306A; if the reading is unsuccessful, the process proceeds to step 306B.

If the identification code 15 is successfully read in step 303 or step 305, the address of the reagent disk 13 from which the identification code 15 was read is linked to the reagent information of the installed reagent container 14 (step 306A).

Thereafter, when dispensing reagents for sample analysis, the dispensing system 28 dispenses from the address on the reagent disk 13 where the reagent container 14 containing the reagent with the requested reagent information is located (step 307). Specifically, the dispensing system 28 dispenses the reagent from the reagent container 14 through the dispensing hole 4 on the lid 2 of the reagent storage cabinet 1.

Here, in the present invention, even during step 307, it is desirable for the control unit 107 to move the reading device 16 to the position of either window 9 or window 10, whichever is the side where reading was successful, and to read the reagent information even when dispensing the reagent, in order to confirm whether the correct reagent has been dispensed.

On the other hand, if reading fails even in step 305, the control unit 107 is notified that the identification code 15 cannot be read (step 306B).

Then, the workflow is terminated (step 308). If there are any unread reagent containers 14 on the reagent disk 13, the processes of steps 301 to 306B are repeated.

Next, the effects of this embodiment will be explained.

The reagent storage cabinet 1 in the automated analyzer 100 of the above-described embodiment 1 of the present invention holds reagents therein and comprises a reagent disk 13 on which are mounted a plurality of reagent containers 14 having identification codes 15 on which information about the reagent is recorded, a main body 3 which houses the reagent disk 13 therein, a lid 2 which covers the top side of the main body 3, a rotating mechanism which rotates the reagent disk 13, and a reading device 16 which reads the identification codes 15, as well as a curved guide 19 which moves the reading device 16 between the side and bottom of the reagent containers 14 mounted on the reagent disk 13.

This allows the identification code 15 attached to the reagent container 14 to be read and recorded in the device while the lid 2 of the reagent storage cabinet 1 is closed, eliminating the need to refill the reagent, and thus making it possible to more effectively prevent measurement errors caused by misplacement than before and to control the quality of the reagent. Furthermore, even without the need to install multiple reading devices 16, reagent containers 14 with identification codes 15 for identifying the reagent on the side or bottom can be used without distinction.

In addition, the reading device 16 reads the identification code 15 when the dispensing system 28 dispenses a reagent, thereby ensuring that the correct reagent is dispensed.

Furthermore, the main body 3 has one or more windows 9, 10 on each of the side and bottom surfaces for reading the identification code 15, and the reading device 16 and curved guide 19 are arranged on the outside of the main body 3. The reading device 16 reads the identification code 15 through the windows 9, 10, thereby preventing the volume of the main body 3 of the reagent storage cabinet 1 from becoming larger.

In addition, because the curved guide 19 is curved when the reagent storage cabinet 1 is viewed vertically, the distance traveled by the reading device 16 moving between the window 9 on the side of the main body 3 and the window 10 on the bottom can be shortened, thereby shortening the time required for processing such as reagent registration.

Example 2
A reagent storage and an automatic analyzer according to a second embodiment of the present invention will be described with reference to Fig. 8. Fig. 8 is a diagram showing a schematic configuration of a reagent storage of the automatic analyzer according to the second embodiment.

The reagent storage cabinet 1A shown in Figure 8 differs from the reagent storage cabinet 1 of Example 1 in that it further includes a cooling device 8 and a curved guide 19A is provided instead of the curved guide 19.

The cooling device 8 is composed of a Peltier element or the like in the reagent storage cabinet 1, and is thermally connected to the kettle 6 to cool the inside of the kettle 6.

The curved guide 19A extends to the top of the lid 2 compared to the curved guide 19, and the highest vertical position of the curved guide 19A is at a height position above the lid 2, which is the standby position of the reading device 16.

The other configurations and operations are approximately the same as those of the reagent storage cabinet and automatic analyzer of Example 1 described above, and details are omitted.

The reagent storage cabinet and automatic analyzer of the second embodiment of the present invention also provide substantially the same effects as the reagent storage cabinet and automatic analyzer of the first embodiment described above.

In addition, the highest vertical position of the curved guide 19A is at a height position equal to or higher than the lid 2, which is the standby position of the reading device 16. This allows the reading device 16 to wait in a position above the kettle 6 where it is less susceptible to the effects of exhaust heat from the cooling device 8, except when reading the identification code 15, and prevents the reading device 16 from being exposed to high temperatures due to exhaust heat. This prevents reading errors due to thermal runaway of the reading device 16.

Example 3
A reagent storage and an automatic analyzer according to a third embodiment of the present invention will be described with reference to Fig. 9. Fig. 9 is a diagram showing a schematic configuration of a reagent storage of the automatic analyzer according to the third embodiment.

The reagent storage cabinet 1B of this embodiment shown in Figure 9 differs from the reagent storage cabinet 1 of Example 1 in that it further includes a tilt block 18 for enabling the reading device 16 to read the identification code 15 from an angle.

When the side of the reagent container 14 is curved, halation may occur when reading the identification code 15 attached to the curved surface, making it difficult for the reader 16 to read the identification code 15. However, by tilting the reader 16, it is possible to prevent reflected light from the identification code 15 from entering the reader 16.

For example, if the distance from the reading device 16 to the identification code 15 is 40 mm, if the reading device 16 is tilted at 15±2° with respect to the identification code 15, the reflected light from the reagent container 14 will not interfere with the reading by the reading device 16, and the reading efficiency can be further improved.

The other configurations and operations are approximately the same as those of the reagent storage cabinet and automatic analyzer of Example 1 described above, and details are omitted.

The reagent storage cabinet and automatic analyzer of Example 3 of the present invention also provide substantially the same effects as the reagent storage cabinet and automatic analyzer of Example 1 described above.

In addition, the reader 16 further includes a tilt block 18 for reading the identification code 15 from an angle, which further reduces read failures. And since fewer read failures increase the angle at which the identification code 15 can be read, the angle at which the reagent container 14 can be placed on the reagent disk 13 can be increased, which has the effect of further improving convenience.

In addition, the tilt block 18 as in this embodiment can also be applied to the reagent storage cabinet 1A described in Example 2.

Example 4
A reagent storage and an automatic analyzer according to a fourth embodiment of the present invention will be described with reference to Fig. 10 to Fig. 12. Fig. 10 is a diagram showing a schematic configuration of a reagent storage of an automatic analyzer according to the fourth embodiment, Fig. 11 is a diagram showing a cross-sectional schematic configuration of the reagent storage, and Fig. 12 is a diagram showing a reagent information reading workflow.

The reagent storage cabinet 1C of this embodiment shown in Figures 10 and 11 differs from the reagent storage cabinet 1 of Example 1 in that the curved guide 19C is configured to move the reading device 16 between the outer and inner sides via the bottom surface of the reagent disk 13.

In this embodiment, the main body 3C of the reagent storage cabinet 1C has a window 9A on the inner surface side in addition to a window 9 on the outer surface side and a window 10 on the bottom surface.

Next, the flow of reading the identification code 15 when reading reagent information in the automatic analyzer of this embodiment will be explained using Figure 12.

Of the steps shown in Figure 12, steps 1101 to 1105 are the same as steps 301 to 305 shown in Figure 7, so details will be omitted.

In FIG. 12, after failure to read the identification code 15 at the bottom position in step 1105, the reader 16 is then moved to a position where it can capture an image of the reagent container 14 through the window 9A on the inner surface of the main body 3 (step 1106).

Then, the reader 16 reads the identification code 15 on the side of the reagent container 14 mounted on the reagent disk 13 through the window 9A, and determines whether the identification code 15 is located on the inner peripheral surface and whether the reading was successful (step 1107). If the reading was successful, the process proceeds to step 1108A. On the other hand, if the reading was unsuccessful, the process proceeds to step 1108B.

Subsequent steps 1108A to 1110 are the same as steps 306A to 308 shown in Figure 3, and so details will also be omitted.

The other configurations and operations are approximately the same as those of the reagent storage cabinet and automatic analyzer of Example 1 described above, and details are omitted.

The reagent storage cabinet and automatic analyzer of Example 4 of the present invention also provide substantially the same effects as the reagent storage cabinet and automatic analyzer of Example 1 described above.

In addition, the curved guide 19C allows the reading device 16 to move between the outer and inner sides via the bottom surface of the reagent disk 13, making it possible to read the identification code 15 affixed to the reagent container 14 even on the inner side of the main body 3. This increases the angle at which the identification code 15 is read, thereby relaxing the constraints on the installation direction when installing the reagent container 14 in the reagent storage cabinet 1, thereby further improving convenience.

The configuration of the curved guide 19C, which moves the reading device 16 between the outer and inner sides via the bottom surface of the reagent disk 13 as in this embodiment, is applicable to the reagent storage cabinet 1A of embodiment 2, the reagent storage cabinet 1B of embodiment 3, or a reagent storage cabinet in embodiment 2 having the structure of embodiment 3.
