[0025] Hereinafter, embodiments of the automatic analyzer and the information reading method in the automatic analyzer will be described using the drawings. In the drawings used in this specification, the same or corresponding components are denoted by the same or similar reference numerals, and duplicate descriptions of these components are sometimes omitted.

[0026] In the following embodiments, the following case is described: the liquid is the specimen, the container to which the first identifier is affixed is the specimen container 102 for holding the specimen, the container holding portion is the specimen disk 114 for holding a plurality of specimen containers 102, and the information related to the automatic analysis device 1 recorded in the second identifier is information related to components or values ​​of the automatic analysis device 1, but of course it is not limited to this.

[0027] In addition to the specimen, the liquid may also be a reagent, which includes system reagents, various consumables, and the like.

[0028] <Example 1>

[0029] use Figures 1 to 7 , Example 1 of an automatic analysis device and an information reading method in the automatic analysis device is described.

[0030] First, use Figure 1 The overall structure of the automatic analyzer will be described. Figure 1 This is a diagram showing an example of a schematic configuration of an automatic analyzer.

[0031] The automatic analyzer 1 is used to analyze a specimen using reagents corresponding to predetermined analysis items, and comprises a specimen disk 114, a specimen dispensing mechanism 115, a reagent storage 116, a reagent dispensing mechanism 119, a reaction tank 120, a biochemical detection unit 121, a control unit 130, a UI unit 110, etc.

[0032] The specimen disk 114 is structured to arrange the specimen containers 102 in a ring shape. The specimen disk 114 rotates and conveys the specimen containers 102 to access positions of the specimen dispensing mechanism 115 during specimen dispensing.

[0033] A first identifier 101 described later is attached to the specimen container 102 , and a code reader (hereinafter referred to as a reader) 106 reads the first identifier 101 and transmits information of the first identifier 101 to the control unit 130 .

[0034] The specimen dispensing mechanism 115 is composed of a rotation drive mechanism, a vertical drive mechanism, and a dispensing probe, and is moved between a specimen suction position and a specimen discharge position by these mechanisms.

[0035] The reagent storage 116 is a mechanism having a cooling function for storing reagent packs containing reagents, and includes a reagent disk 117 and a reagent pack holding unit 118 .

[0036] The reagent pack holding portions 118 are arranged in a ring shape on the reagent disk 117, and a plurality of reagent packs can be held. The reagent disk 117 has a rotation drive mechanism, and each reagent pack is moved to a predetermined position on the circumference by a rotational motion.

[0037] The reagent dispensing mechanism 119 is composed of a rotation drive mechanism, an up-and-down drive mechanism, and a dispensing probe. The reagent dispensing mechanism 119 rotates and descends toward the position of a predetermined type of reagent package on the reagent disk 117 to suck a predetermined amount of reagent. After sucking the reagent, the reagent dispensing mechanism 119 rises. Then, as the reagent discharge destination, it rotates and descends toward a predetermined reaction unit on the reaction tank 120 to discharge each reagent.

[0038] The reaction vessel 120 is temperature-controlled to an appropriate temperature in order to promote the reaction between the sample and the reagent.

[0039] The biochemical analysis flow is described below.

[0040] Initially, the sample dispensing mechanism 115 dispenses a predetermined amount of sample into a predetermined reaction unit on the reaction tank 120. Then, the reaction tank 120 rotates to move the reaction unit from which the sample has been discharged to an access position of the reagent dispensing mechanism 119, and the reagent dispensing mechanism 119 dispenses a predetermined amount of reagent into the reaction unit from which the sample has been discharged.

[0041] When the reaction process between the specimen and the reagent on the reaction tank 120 is completed, the reaction tank 120 is rotated to move the reaction unit in which the reaction liquid after the reaction is completed is placed to the installation position of the biochemical detection unit 121 .

[0042] Then, the biochemical detection unit 121 measures the reaction signal.

[0043] The mechanism described above in the automatic analyzer 1 is referred to as an analysis operation unit.

[0044] Furthermore, the automatic analyzer 1 includes a control unit 130 for controlling the operation of each device in the automatic analyzer 1 and a UI unit 110 .

[0045] The control unit 130 is constituted by, for example, a hardware substrate and a computer, and has a storage device 132 such as a hard disk, the mechanism operation control unit 108 , and the analysis operation control unit 109 built therein.

[0046] The storage device 132 stores control parameters and the like corresponding to each unit.

[0047] The control unit 130 can be composed of a dedicated circuit substrate as hardware, or can be composed of software executed by a computer. In the case of being composed of hardware, it can be realized by integrating multiple operators that perform processing on a wiring substrate, or in a semiconductor chip or package. In the case of being composed of software, it can be realized by carrying a high-speed general-purpose CPU on a computer and running a program for performing the desired calculation processing. Existing devices can also be upgraded by recording a recording medium with the program recorded. In addition, these devices, circuits, and computers are connected through a wired or wireless network to appropriately send and receive data.

[0048] The UI unit 110 is composed of a display device such as a display, and input devices such as a mouse and a keyboard.

[0049] Next, use Figure 2 The following figures illustrate the characteristic structure of this embodiment. Figure 2 The structure for reading information will be described. Figure 2 This is a diagram schematically showing the structure of information reading.

[0050] As described above, the first identifier 101 such as a one-dimensional code (barcode) is affixed to the outer wall of the specimen container 102 that contains a liquid such as a specimen. That is, the first identifier stores information related to the contained liquid.

[0051] In addition, the container to which the first identifier is attached is not limited to the specimen container 102 containing a liquid as a specimen, and may be, for example, a container containing a liquid such as a reagent. In addition, the first identifier 101 may be not only a one-dimensional code but also a two-dimensional code, and may be composed of a semiconductor storage medium, a magnetic storage medium, an optical storage medium, etc.

[0052] The specimen container 102 is fixed to one of the plurality of holding areas 103A located in the specimen disk 114. The holding area 103A can hold a plurality of specimen containers 102. The holding area 103A may be a rectangular area such as a rack capable of holding a plurality of specimen containers, or a disc-like area capable of holding specimen containers in a circular shape, without particular limitation.

[0053] In addition, a sensor 113 may be provided to determine the presence or absence of a container when the reader 106 reads. The sensor 113 may use an optical sensor such as a reflective or transmissive sensor or an imaging sensor or an acoustic sensor, and the reading position may be the same as that of the reader 106.

[0054] In the object 105 such as consumables or a part of the device structure used in the automatic analyzer 1 , a second identifier 104 such as a two-dimensional code for storing information related to the automatic analyzer 1 is provided in the region 105A.

[0055] In addition, the second identifier 104 does not need to be set on the object 105, and can also be displayed on a screen of a smart device, printed on paper or a label, etc. The second identifier 104, like the first identifier 101, is not only a two-dimensional code, but can also be a one-dimensional code, and can also be composed of a semiconductor storage medium, a magnetic storage medium, an optical storage medium, etc.

[0056] In this embodiment, the reader 106 is fixed at a predetermined position in the automatic analysis device 1, and the reader 106 can read the information stored in the first identifier 101 located in the holding area 103A and the second identifier 104 located in the area 105A. In addition, its reading range 111 is fixed to include the holding area 103A and the area 105A. Preferably, the first identifier 101 and the second identifier 104 can be read at the same time.

[0057] After reading, the information of the first identifier 101 and the second identifier 104 is processed by the mechanism operation control unit 108 or the analysis operation control unit 109 and stored in the storage device 132, and the information related to the UI unit 110 is displayed. The operation of the reader 106 is controlled by the mechanism operation control unit 108 and the analysis operation control unit 109.

[0058] Regarding the reading range 111 of the reader 106, at least one of the holding area 103A and the area 105A can be directly read optically. In the present embodiment, the second identifier 104 of the area 105A can be directly read optically. In contrast, a first optical path branching portion 107 such as a reflector is disposed within the reading range 111 between the reader 106 and the holding area 103A, and a portion of the optical path of the reading range 111 is bent to read the first identifier 101.

[0059] In addition, the first optical path branch portion 107 provided within the reading range 111 can be provided at one or more locations between the reader 106 and the holding area 103A and between the reader 106 and the area 105A, and can be provided at one location between the reader 106 and the area 105A where the second identifier 104 is located, or at two locations between the reader 106 and the holding area 103A and between the reader 106 and the area 105A (the method of Example 3, details of which will be described later).

[0060] FIG. 3A to FIG. 3C The following is a schematic diagram of an example of a method of dividing an image into sections when the reader 106 is capturing an image. In this embodiment, it is preferred that the reader 106 can simultaneously read the information stored in the first identifier 101 located in the holding area 103A and the second identifier 104 located in the area 105A. Figure 3A As shown, in the image region 301 at the time of imaging, the specimen container 102 to which the first identifier 101 is attached and the object 105 such as the consumables to which the second identifier 104 is attached are reflected in the same image.

[0061] Therefore, it is preferable to divide the image area 301 projected in the same image as the setting 302 of the decoding area on the software. For example, it is preferable to read the information of the first identifier 101 in the first identifier information reading mode. Figure 3B In the second identifier information reading mode for reading the information of the second identifier 104, the area 105A side is processed as the decoding area. Figure 3C In this way, the process is performed with the holding area 103A side as the decoding area, and the range of the reading area is switched to perform reading.

[0062] Alternatively, the decoding area may not be set and reading may be performed simultaneously.

[0063] Furthermore, it is preferable that the reader 106 can change the detection setting of reading between a first identifier information reading mode for reading information of the first identifier 101 and a second identifier information reading mode for reading information of the second identifier 104 .

[0064] For example, when reading the information of the first identifier 101 in the holding area 103A, since it passes through the first optical path branching portion 107, it is possible to make adjustments such as extending the exposure time and increasing the light amount compared to the case of reading the information of the second identifier 104 in the area 105A.

[0065] The mode switching between the first identifier information reading mode and the second identifier information reading mode is preferably performed on a screen displayed on the UI unit 110 , but the present invention is not limited thereto.

[0066] Figure 4 1 is a schematic diagram showing an embodiment of a cover provided at the second identifier reading position. A cover 402 is provided at the setting position of the second identifier 104. The cover 402 is provided to ensure the performance and safety of the reader, and may not be provided depending on the structure.

[0067] A cover identifier 401 is attached to the reader side of the cover 402. By reading the cover identifier 401 with the reader 106 at a certain timing on the system, it can be confirmed that the cover is closed.

[0068] Next, use Figure 5 The flow of reading the first identifier 101 will be described. Figure 5 101 is a flowchart showing the flow of reading the first identifier 101. The following operations are controlled by the mechanism operation control unit 108.

[0069] When the first identifier 101 is started to be read, the specimen disk 114 moves to the home position. As a result, one of the plurality of holding areas 103A located in the specimen disk 114 moves to a position suitable for starting reading (S501). Here, the home position refers to only one specific location determined for each movable mechanism. There is also a home position on the specimen disk 114. And, when the specimen disk 114 is in the home position, a specific one of the plurality of holding areas 103A is located at a location suitable for starting reading. In addition, when the specimen disk 114 is located at the home position when the first identifier 101 is started to be read, the specimen disk 114 does not move.

[0070] Next, it is determined based on the sensor result of the sensor 113 whether the specimen container 102 is set in the holding area 103A (S502). When there is a holding area 103A where the presence of the specimen container 102 has not been confirmed ("Yes" in S503), the specimen disk 114 moves the next holding area 103A to the reading position (S504). It is confirmed whether containers are set for all the holding areas 103A ("No" in S503), and when it is determined that there is no specimen container 102 on the specimen disk 114 ("No" in S505), the processing is completed. As long as there is one specimen container 102 ("Yes" in S505), it is moved to the original position (S506) and the processing enters S507. In addition, when the specimen disk 114 is at the original position at S505, S506 is not required.

[0071] Next, it is determined whether the first identifier 101 can be read and whether the information of the first identifier 101 can be recorded through the above-mentioned processing of S501 to S505 (S507).

[0072] When it is determined that information can be read and recorded, in addition to the setting position information of the specimen container 102 in the holding area 103A, the corresponding first identifier 101 information is associated and recorded in the storage device 132 (S508), and the required information is displayed on the UI unit 110 (S509), so that the processing enters S512.

[0073] In contrast, when it is determined in S507 that the sample container 102 cannot be read or cannot be recorded, the setting position information of the sample container 102 in the holding area 103A is recorded in the storage device 132 (S510), an alarm indicating that there is an unreadable sample container 102 is displayed on the UI unit 110 (S511), and the processing enters S512.

[0074] If it is determined in S503 that a specimen container 102 exists in another holding area 103A, it is determined whether it is necessary to continuously read the first identifier 101 of the other specimen container 102 (S512). If reading is necessary, the next container is moved to a position suitable for reading (S513), and the process is returned to S507 to continue reading. If reading is not necessary, the process is completed.

[0075] Next, use Figure 6 and Figure 7 The flow of reading the second identifier 104 will be described. Figure 6 The reading process of the second identifier 104 is shown by a flowchart. Figure 7 express Figure 6 part of the process.

[0076] In this embodiment, since a cover 402 is provided at the second identifier reading position, Figure 6 As shown, the user opens the cover 402 (S601) when starting to read the second identifier 104. If the cover 402 is not provided, S601 is omitted.

[0077] Next, the user selects a reading mode for the second identifier 104 from the UI unit 110 or the like (S602). After that, the mechanism operation control unit 108 changes the setting of the reader 106 to the setting for reading the second identifier (S603). Alternatively, the setting of the reader 106 may not be changed, and a preparatory mechanism operation for reading the second identifier 104 may be performed on the mechanism.

[0078] Next, the mechanism operation control unit 108 determines whether the second identifier 104 can be read and whether the information of the second identifier 104 can be recorded (S604). If it is determined that the information can be read and recorded, the process proceeds to step S605. On the other hand, if it is determined that the information cannot be read or recorded, the process proceeds to step S700.

[0079] like Figure 7 As shown, S700 is composed of the following steps.

[0080] First, in Figure 6 After S604 shown, the mechanism operation control unit 108 displays the first error warning (S701) that reading is impossible on the UI unit 110, and advances the process to S702.

[0081] After that, the mechanism operation control unit 108 performs reading again after a certain time has passed (S702). Based on this, it is determined whether the second identifier 104 can be read and whether the information of the second identifier 104 can be recorded by the re-reading (S703). If it is determined that the reading can be performed and the information can be recorded, the process proceeds to step S605. On the other hand, if it is determined that the reading cannot be performed or the read information cannot be recorded, the process proceeds to step S704.

[0082] Next, the mechanism operation control unit 108 displays a warning that there is an abnormality in the reading state on the UI unit 110 ( S704 ), ends the reading mode of the second identifier 104 of the device ( S705 ), and proceeds to S612 .

[0083] return Figure 6 The mechanism operation control unit 108 determines whether the second identifier 104 is information different from the cover identifier 401 (S605).

[0084] If it is determined in S605 that the information is the same as the cover identifier 401, the mechanism operation control unit 108 displays a warning on the UI unit 110 that the information is in an unreadable state because the cover 402 is still installed (S606). According to the situation, the setting is changed to read the first identifier (S607), and the process returns to S601. In addition, the setting of the reader 106 may not be changed, and the preparatory mechanism operation for reading the first identifier 101 may be implemented on the mechanism.

[0085] On the other hand, when it is determined in S605 that the information is different from the cover identifier 401, the mechanism operation control unit 108 records the information of the second identifier 104 in the storage device 132 (S608), displays the recorded information on the UI unit 110 (S609), and then advances the process to S610.

[0086] Next, the mechanism operation control unit 108 determines whether to register a plurality of second identifiers 104 (S610). If it is determined that the reading is to be performed continuously, the process returns to S604. If it is determined that the reading is not to be performed continuously, the process proceeds to S611, and the second identifier reading mode is terminated from the UI unit 110 or the like (S611).

[0087] The user closes the cover 402 at the second identifier reading position opened in S601 (S612). At this time, in order to confirm whether the cover 402 is installed as it is, the mechanism operation control unit 108 determines whether the cover identifier 401 can be read (S613). If it is determined that it cannot be read, the mechanism operation control unit 108 displays an alarm on the UI unit 110 that the cover 402 is not installed and the reading state is not possible (S614), and the process returns to S612.

[0088] On the other hand, if it is determined that the reading is possible in S613, the mechanism operation control unit 108 changes the setting to read the first identifier according to the situation and ends (S615). It is also possible not to change the setting of the reader 106 in S615, and to implement the preparatory mechanism action for reading the first identifier on the mechanism.

[0089] Next, the effects of this embodiment will be described.

[0090] The above-mentioned automatic analyzer 1 comprises: a specimen disk 114 for holding a specimen container 102, wherein the specimen container 102 has a first identifier 101 for storing information related to the contained liquid attached to its outer wall; a holding area 103A, which is located in the specimen disk 114 and is provided with the specimen container 102 attached with the first identifier 101; an area 105A, which is provided with a second identifier 104 for storing information related to the automatic analyzer 1; and a reader 106, whose reading range 111 includes the holding area 103A and the area 105A and is fixed to be able to read the information stored in the first identifier 101 and the second identifier 104.

[0091] According to this embodiment, even if a plurality of reading objects are arranged at different reading positions, the reading angles can be divided and read simultaneously, and the installation area of ​​the automatic analyzer 1 can be reduced compared to the related art, thereby achieving miniaturization of the device.

[0092] In addition, regarding the reading range 111, at least one of the holding area 103A and the area 105A can be directly read optically, so there is no need to configure a plurality of first optical path branching portions 107 and the like, and the number of components can be reduced.

[0093] Furthermore, a first optical path branching portion 107 is provided between the reader 106 and the holding area 103A or between the reader 106 and the area 105A within the reading range 111, thereby increasing the degree of freedom in setting the positions of the holding areas 103A and 105A and partially alleviating the constraints on the device layout.

[0094] In addition, the reader 106 is capable of changing the detection settings for reading in a first identifier information reading mode for reading information of the first identifier 101 and in a second identifier information reading mode for reading information of the second identifier 104. Thus, settings suitable for reading the first identifier 101 and settings suitable for reading the second identifier 104 can be made in a single reader 106, and information reading of any identifier can be performed with high precision.

[0095] <Example 2>

In addition, the reading range 111C is fixed to include the holding area 103A, the area 105A, and the second holding area 603, and in addition to the first optical path branching portion 107 such as a reflecting mirror, a third optical path branching portion 604 is also arranged in the reading range 111C.

[0106] In addition, the third optical path branching portion 604 is connected to a driving portion 605 that moves the position of the third optical path branching portion 604, and the reading range 111C changes so that any one of the area 105A and the second holding area 603 is included in the reading range 111C. The second identifier 104 located in the area 105A can be directly optically detected without passing through the third optical path branching portion 604, while the third identifier 601 located in the second holding area 603 can be detected through the third optical path branching portion 604.

[0107] In addition, the moving method of the third optical path branching portion 604 is not limited to Fig.10 The rotation shown can also be performed by moving up, down, left, and right.
