[0009] Hereinafter, Figures 1 to 6 an embodiment of the automatic analysis device will be described. In the drawings used in this specification, the same or corresponding structural elements are denoted by the same or similar reference numerals, and repeated descriptions of these structural elements are sometimes omitted.

[0010] In the following embodiments, a biochemical analysis project group is exemplified as the first analysis project group, and an immunoassay analysis project group different from the first analysis project group is exemplified as the second analysis project group. However, the first analysis project group and the second analysis project group are not limited to these projects and can be appropriately selected.

[0011] First, Figure 1 the overall structure of the automatic analysis device will be described. Figure 1 FIG. is a diagram showing an outline of the automatic analysis device. In an automatic analysis device (also referred to as a composite automatic analysis device) that performs two measurements of a first analysis project and a second analysis project in one housing, the configuration of containers related to reagents (hereinafter referred to as system reagents) commonly used for multiple analysis projects in the liquid to be analyzed and units related to the system reagents are shown. For the system reagents commonly used for multiple analysis projects, there are reagents corresponding to each analysis project, hereinafter referred to as assay reagents.

[0012] The automatic analysis device 1 is a device for analyzing a specimen using a reagent corresponding to a prescribed analysis item, and includes: a specimen tray 25, a specimen dispensing mechanism 50, a reagent tray 40, a reagent dispensing mechanism 42, a reaction tank 52, an immunoassay unit 30, an ISE assay unit 58, a container cleaning mechanism 56 for cleaning reaction containers for biochemical analysis, a reader 18 for reading RFID, a control device 10, etc.

[0013] The specimen tray 25 is configured to be able to annularly hold a plurality of specimen containers (not shown) for accommodating specimens to be analyzed in a first analysis item and a second analysis item, and includes an access position (specimen suction position) of the specimen dispensing mechanism 50. The specimen tray 25 rotates immediately before the specimen dispensing mechanism 50 sucks the specimen to be analyzed, thereby conveying the specimen container to the specimen suction position.

[0014] The reaction tank 52 annularly has positions for holding reaction containers for biochemical analysis and ISE analysis and disposable reaction containers for immunoassay. Hereinafter, unless otherwise specified, the "reaction container" refers to both reaction containers for biochemical analysis and ISE analysis and disposable reaction containers for immunoassay. The reaction tank 52 controls the temperature to promote the reaction between the specimen and the reagent, and has a rotational drive mechanism that moves the reaction containers on the reaction tank 52 to a prescribed position.

[0015] The specimen dispensing mechanism 50 includes a rotational drive mechanism, an up-and-down drive mechanism, and a specimen probe, and enables access to the reaction containers at the specimen discharge position where specimens are dispensed onto the reaction tank 52. The rotational drive mechanism and the up-and-down drive mechanism move between the specimen suction position and the specimen discharge position, suck the specimen at the specimen suction position, and discharge it into the reaction containers on the reaction tank 52. After discharging the specimen, it moves to the specimen probe cleaning tank 54, is held in the detergent container 150, and is cleaned using the detergent supplied by controlling the opening and closing of the solenoid valve 152 via the flow path 155, and then moves on to the dispensing operation of the next specimen.

[0016] The reagent tray 40 is configured to be able to annularly hold a plurality of reagent containers (not shown) for accommodating reagents for causing a specimen to react to generate a reaction solution, and has an access position (reagent suction position) of the reagent dispensing mechanism 42. The reagent tray 40 rotates immediately before the reagent dispensing mechanism 42 sucks the reagent, thereby conveying the reagent container to the reagent suction position. In addition, it includes a cold insulation mechanism for keeping the reagent container cold. In addition, the reagent tray 40 may be configured to be able to arrange a plurality of reagent containers in a double ring.

[0017] The reagent containers can also be composed of multiple different reagent bottles respectively. When the shapes of the reagent containers are different, dedicated positions for holding each reagent container can be set, or the shape can be such that two reagent containers can be held at one position.

[0018] The reagent dispensing mechanism 42 is composed of a rotation drive mechanism, an up-and-down drive mechanism, and a reagent probe, enabling access to the reaction vessel at the reagent discharge position for dispensing reagents placed on the reaction tank 52. It moves between the reagent suction position and the reagent discharge position through the rotation drive mechanism and the up-and-down drive mechanism, sucks the reagent at the reagent suction position, and discharges it to the reaction vessel on the reaction tank 52. After discharging the reagent, it moves to the reagent probe cleaning tank 44, remains in the cleaning liquid container 131, and is cleaned using the cleaning liquid supplied under the control of the opening and closing of the solenoid valve 141 via the flow paths 137 and 138, and then moves on to the dispensing operation of the next reagent.

[0019] In addition, the specimen dispensing mechanism 50 and the reagent dispensing mechanism 42 are not limited to the structure that accesses each position through a rotational movement, and can also be a structure that accesses each position through a linear movement.

[0020] After dispensing the specimen and the reagent, the reaction is promoted on the temperature-controlled reaction tank 52. When the reaction process between the specimen and the reagent on the reaction tank 52 ends, the reaction tank 52 rotates, and the reaction vessel containing the reaction liquid for the biochemical item is measured for the transmitted light by a photometer (not shown) provided near the reaction tank 52. The measurement result is sent to the control device 10.

[0021] When the measurement item is ISE analysis, the reaction vessel containing the specimen for ISE analysis is moved to the specimen suction position of the ISE measurement unit 58. Through the syringe 59 of the ISE measurement unit 58, the specimen is sucked into the flow path inside the ISE electrode. Then, the potential difference between the measurement electrode and the reference electrode is measured, and the reference electrode sucks the reference liquid held in the reference liquid container 151 and the supply of which is controlled by the opening and closing of the solenoid valve 154 provided on the flow path 157. The information on the potential difference is sent to the control device 10. The flow path inside the ISE measurement unit 58 for analysis is cleaned with the reference liquid or pure water for the next analysis.

[0022] When the measurement item is an immunoassay item, the disposable reaction container on the reaction tank 52 containing the reaction solution for the immunoassay item is moved to the reaction container transfer position and transferred to the immunoassay unit 30 by a reaction container transfer mechanism (not shown). In the disposable reaction container transferred into the immunoassay unit 30, B / F separation is performed to separate unreacted components and reaction components from the liquid after the sample and the reagent have reacted. Then, the reaction solution suction nozzle sucks the reaction solution, feeds it to the immuno unit (also called the flow cell unit), measures the signal, and sends the measurement result to the control device 10.

[0023] In the immunoassay unit 30, a buffer nozzle 32, a cleaning solution nozzle 34, a replacement solution nozzle 36, a B / F separation unit, a reaction solution suction nozzle, and an immuno unit are respectively provided.

[0024] The buffer solution in the buffer solution container 130 is provided to the buffer nozzle 32 via the flow path 136 by the suction and discharge actions of the syringe 133. A solenoid valve 140 is arranged on the flow path 136. The buffer solution is discharged into the reaction container arranged in the B / F separation unit.

[0025] The cleaning solution in the cleaning solution container 131 is provided to the cleaning solution nozzle 34 via the flow path 137 by the discharge action of the pump 134. The cleaning solution discharged from the cleaning solution nozzle 34 is provided inside the immuno unit where the measurement of the reaction solution has ended from the reaction solution suction nozzle for cleaning. In addition, the cleaning solution in the cleaning solution container 131 is provided to the reagent probe cleaning tank 44 via the flow path 138 branched from the flow path 137 by the discharge action of the pump 134. A solenoid valve 142 is arranged on the part of the flow path 137 closer to the cleaning solution nozzle 34 side than the bifurcation part with the flow path 138, and a solenoid valve 141 is arranged on the flow path 138.

[0026] The replacement solution in the replacement solution container 132 is provided to the replacement solution nozzle 36 via the flow path 139 by the discharge action of the pump 135. The replacement solution discharged from the replacement solution nozzle 36 is sucked by the reaction solution suction nozzle and provided into the immuno unit before measurement with the immuno unit and after cleaning with the cleaning solution. A solenoid valve 143 is arranged on the flow path 139.

[0027] The reaction container on the reaction tank 52 for biochemical analysis and ISE analysis discharges the residues in the reaction container through the container cleaning mechanism 56. Then, it is cleaned with the detergent held in the detergent container 150 and supplied via the flow path 156 branched from the flow path 155 and controlled by the opening and closing of the solenoid valve 153 for the next analysis.

[0028] In the automatic analysis device 1 of the present embodiment, the system reagent used in the biochemical analysis project group is a detergent, and the system reagents used in the immunoassay project group are a buffer solution, a cleaning solution, and a replacement solution. In addition, a standard solution container 151 for storing the standard solution of the system reagent for ISE analysis is arranged beside the detergent container 150.

[0029] The reader 18 reads the information of the label that stores information about the reagent given to the reagent container, or the label that stores information related to the automatic analysis device 1 given to an object such as a consumable or a part of the device structure used in the automatic analysis device 1.

[0030] The housing 20 houses a biochemical analysis unit including a reaction tank 52, a container cleaning mechanism 56, and a photometer, an ISE measurement unit 58, and an immunoassay unit 30.

[0031] The automatic analysis device 1 includes a control device 10 that controls the operations of various devices in the automatic analysis device 1, such as the specimen tray 25 or the specimen dispensing mechanism 50.

[0032] The control device 10 may be composed of a computer having input devices such as a display 14, a keyboard 15, and a mouse 16, a storage unit 13, a control unit 12 composed of a CPU, a memory, etc. It may be composed of one computer or multiple computers, and there is no particular limitation.

[0033] In the present embodiment, the display 14 displays the replacement steps of the detergent container 150, the standard solution container 151, or the buffer solution container 130, the cleaning solution container 131, and the replacement solution container 132. The detailed content will be described Figure 1 later.

[0034] In the present embodiment, the keyboard 15 or the mouse 16 is used for the user to input a replacement request for the detergent container 150, the standard solution container 151, or the buffer solution container 130, the cleaning solution container 131, and the replacement solution container 132.

[0035] In addition, a touch panel type display may be used as the display 14 instead of the keyboard 15 or the mouse 16, or in addition to the keyboard 15 or the mouse 16, a touch panel type display may also be used as the display 14, so that the display 14 serves as both a display unit and an input unit.

[0036] The control unit 12 of the control device 10 controls the operations of various devices based on various programs recorded in the storage device. In addition, the control processing of the operations performed by the control unit 12 may be summarized into one program, or may be divided into multiple programs separately, or may be a combination of these programs. In addition, part or all of the program may be implemented on dedicated hardware or may be modularized.

[0037] The above is the structure of the automatic analysis device 1 of this embodiment.

[0038] In addition, the structure of the automatic analysis device is not limited to the structure in which the reactions of the reaction vessel for the first analysis item and the disposable reaction vessel for the second analysis item are carried out simultaneously on the reaction tank 52. Figure 1 It may also be a structure having an incubator for the second analysis item in addition to the reaction tank 52. In addition, although a common sample dispensing mechanism and reagent dispensing mechanism are used in the first analysis item and the second analysis item, they may also be configured to have each mechanism separately.

[0039] In addition, let the first analysis item be a biochemical item and the second analysis item be an immunological item, but as long as they are different, they may also be set as other analysis items.

[0040] In addition, it is assumed that different reagents are used in the first analysis item and the second analysis item, but they may also be set as common reagents, and there is no particular limitation.

[0041] In addition, the automatic analysis device is not limited to Figure 1 the shown single analysis module structure mode, and a structure in which two or more analysis modules capable of measuring various identical or different analysis items or pretreatment modules for pretreatment are connected by a transfer device may also be adopted.

[0042] Next, the characteristic structure of this embodiment will be described using Figure 2 the figures from and after. Figure 2 is a diagram showing an overview of the door of the automatic analysis device 1, Figure 3 is a diagram showing the state when the left door is open, Figure 4 is a diagram showing the state when the right door is open, Figure 5 is a diagram showing a sectional view of the device downward from Figure 2 plane A, Figure 6 is a flowchart showing the system reagent replacement operation.

[0043] The automatic analysis device 1 separates the areas of the system reagents by each analysis item group. Specifically, when the housing 20 is set to include a biochemical analysis unit and an immunoassay unit 30 that process and measure specimens, reagents, and reaction solutions as a first area, and a second area disposed on the lower side in the vertical direction of the first area, the second area is divided into a first block (inside the left door 60) that houses the detergent container 150, and a second block (inside the right door 62) that houses the buffer solution container 130, the cleaning solution container 131, and the replacement container 132. The detergent container 150 stores the first liquid used in the analysis in the biochemical analysis unit, and the buffer solution container 130, the cleaning solution container 131, and the replacement container 132 store the second liquid used in the analysis in the immunoassay unit 30. In this embodiment, the standard solution container 151 used in the analysis in the ISE measurement unit 58 is stored in the first block.

[0044] After being divided into such a first block and a second block, the detergent container 150, the standard solution container 151, the buffer solution container 130, the cleaning solution container 131, and the replacement solution container 132 are arranged on the surface of the floor 22 that constitutes the bottom surface of the housing 20.

[0045] Similarly, a tray 160 for placing system reagents is provided on the surface of the floor 22 at the same horizontal level, and the detergent container 150, the standard solution container 151, the buffer solution container 130, the cleaning solution container 131, and the replacement solution container 132 are arranged at horizontal positions with respect to each other on the tray 160.

[0046] In addition, in Figure 1 the system reagents are horizontally arranged on the tray 160 on the floor 22 that constitutes the bottom of the housing 20, but they can be horizontally arranged within the housing 20 regardless of whether a tray is used in other mechanisms.

[0047] In addition, a partition wall 23 between the detergent container 150 and the standard solution container 151 arranged in the first block and the buffer solution container 130, the cleaning solution container 131, and the replacement solution container 132 arranged in the second block can reliably prevent contamination and mis-taking caused by the scattering of reagents during replacement.

[0048] In addition, the flow paths 155, 156, 157 (first flow paths) connecting the detergent container 150, the standard solution container 151, the specimen probe cleaning tank 54, the container cleaning mechanism 56, and the ISE measurement unit 58, and the flow paths 136, 137, 138, 139 (second flow paths) connecting the buffer solution container 130, the cleaning solution container 131, the replacement solution container 132, and the immunoassay unit 30 are arranged so as not to cross.

[0049] In addition, as Figure 2As shown, it includes: a left door 60, which is set so that the user can access the first block but not the second block; and a right door 62, which is set so that the user cannot access the first block but can access the second block.

[0050] The left door 60 and the right door 62 are as Figure 3 shown. In a state where only the left door 60 is open and the right door 62 is closed, the buffer solution container 130, the cleaning solution container 131, and the displacement solution container 132 in the second block cannot be accessed due to the closed right door 62. In contrast, since the left door 60 is open, the detergent container 150 or the standard solution container 151 in the first block can be accessed.

[0051] In contrast, as Figure 4 shown. In a state where only the right door 62 is open and the left door 60 is closed, the detergent container 150 or the standard solution container 151 in the first block cannot be accessed due to the closed left door 60. In contrast, since the right door 62 is open, the buffer solution container 130, the cleaning solution container 131, and the displacement solution container 132 in the second block can be accessed.

[0052] In addition, in Figure 3 and Figure 4 the wall 23 is omitted. The user uses the left door 60 and the right door 62 to perform access control, so that it is possible to fully prevent mis-taking during reagent replacement. By combining with the wall 23 that prevents contamination during reagent replacement, the reliability of the device can be further improved.

[0053] In addition, as Figure 1 shown, a replacement wizard for system reagents can also be displayed on the display 14. As an example of the wizard displayed on the display 14 after RFID reading, for example, it can be cited that when replacing the system reagents for biochemical analysis, that is, the detergent container 150 or the standard solution container 151, the left door 60 is displayed as open. By opening the left door 60 according to the wizard, the user can prevent mis-accessing the system reagents for immunoassay, that is, the buffer solution container 130, the cleaning solution container 131, and the displacement solution container 132.

[0054] As Figure 5 shown, a second area vertically below the first area including the biochemical analysis unit and the immunoassay unit 30 is set with a water system area 100 including a first block and a second block, and an electrical system area 105 separated from the water system area 100 by a wall 24. In addition, the water system area 100 and the electrical system area 105 are not limited to one each. As long as they are separated by a wall from each other, there can be multiple water system areas 100 and electrical system areas 105.

[0055] The water system area 100 houses the first mechanism 120 involved in the water circulation system, and the electrical system area 105 houses the second mechanism involved in the electrical system other than the cables through which drive current flows.

[0056] In addition to the syringe 133, pumps 134, 135, the first mechanism 120 further includes flow paths 136, 137, 138, 139, 155, 156, 157 through which the first liquid or the second liquid flows, solenoid valves 140, 141, 142, 143, 152, 153, 154 in the flow paths 136, 137, 138, 139, 155, 156, 157, and at least one of the water flow paths starting from the water supply port 102 for introducing the water used in the reaction tank 52 into the automatic analyzer 1.

[0057] The second mechanism is composed of a control device 10 including a control unit 12, a power supply 17 for the control device 10, a power supply port 107 for supplying power to the power supply 17 from outside the automatic analyzer 1, and the like.

[0058] Next, use Figure 6 to illustrate the process when the user replaces the system reagent. Hereinafter, "su" represents the user's processing, and "ss" represents the processing of the control unit 12.

[0059] First, when the user requests the replacement of the system reagent using the GUI on the display 14 (su1), the control unit 12 causes the system reagent that has received the replacement request to migrate to a replaceable state (ss1). Next, the control unit 12 displays a wizard for reading the RFID of the system reagent on the display 14 (ss2).

[0060] After the user confirms the display on the display 14, the user places the RFID tag of the system reagent container in front of the reader 18 (su2). When the RFID tag is placed in front of the reader 18, the reader 18 reads the reagent information (ss3), and the control unit 12 causes the display 14 to display a wizard for the configuration method corresponding to the read system reagent (ss4).

[0061] The user configures or replaces the system reagent according to the wizard displayed on the display 14 (su3). After the configuration or replacement is completed, the user presses the registration completion button on the display 14 (su4). When the control unit 12 recognizes the pressing of the registration completion button, it updates the screen reagent information (ss5) and completes the replacement process.

[0062] Next, the effects of this embodiment will be described.

[0063] The automatic analysis device 1 of this embodiment includes: a biochemical analysis unit for analyzing a first analysis item group; an immunoassay unit 30 for analyzing a second analysis item group different from the first analysis item group; an ISE measurement unit 58 for performing ISE analysis; and a housing 20 for housing the biochemical analysis unit, the immunoassay unit 30, and the ISE measurement unit 58. When a first area including the biochemical analysis unit, the immunoassay unit 30, and the ISE measurement unit 58, and a second area arranged on the lower side in the vertical direction of the first area are set, the second area is divided into a first block for accommodating a detergent container 150 for storing a first liquid used in the analysis of the biochemical analysis unit, and a standard solution container 151 for storing a standard solution used in the measurement of the ISE measurement unit; and a second block for accommodating a buffer container 130, a cleaning solution container 131, and a replacement solution container 132 for storing a second liquid used in the analysis of the immunoassay unit 30.

[0064] On this basis, the detergent container 150, the standard solution container 151, the buffer container 130, the cleaning solution container 131, and the replacement solution container 132 are arranged on the surface of the floor 22 constituting the bottom surface of the housing 20, or arranged in horizontally parallel positions.

[0065] In the structure of such an automatic analysis device 1, since the arrangement areas of the system reagents are divided, the flow paths for each analysis item can be arranged so as not to cross the flow paths of other analysis items, and the maintainability can be improved. In addition, the operations when replacing each system reagent can be made to have a sense of unity, the burden on the user to remember the steps can be reduced, and the reliability can be improved. In addition, for example, the distance for lifting a heavy bottle during replacement becomes shorter, which also has the effect of reducing the burden on the user.

[0066] In addition, since there is a dividing wall 23 arranged between the first block and the second block, the contamination of the reagents can be reliably prevented.

[0067] In addition, it includes a first flow path connecting the detergent container 150, the standard solution container 151, the biochemical analysis unit, and the ISE measurement unit 58; and a second flow path connecting the buffer container 130, the cleaning solution container 131, the replacement solution container 132, and the immunoassay unit 30. The first flow path and the second flow path are arranged so as not to cross, so that even in the event of a malfunction such as a liquid leak, the impact on other flow paths can be reduced, and the maintainability such as replacement can be further improved.

[0068] In addition, it includes: a left door 60, which is set so that the user can access the first block but not the second block; and a right door 62, which is set so that the user cannot access the first block but can access the second block, enabling access from different doors, and thus making it easier to suppress replacement errors while maintaining the operating feel of the existing product.

[0069] In addition, the second area includes an electrical system area 105 separated from the water system area 100 by a wall 24. The water system area 100 houses a first mechanism 120 related to the water circulation system, and the electrical system area 105 houses a second mechanism related to the electrical system other than the cables through which the driving current flows, thereby minimizing the possibility of failures such as electric leakage.

[0070] Furthermore, by having a keyboard 15, a mouse 16 for receiving inputs related to the user's replacement requests for the detergent container 150, the standard solution container 151, or the buffer solution container 130, the cleaning solution container 131, the replacement solution container 132, and a display 14 for displaying the replacement steps of the detergent container 150, the standard solution container 151, or the buffer solution container 130, the cleaning solution container 131, the replacement solution container 132, even users who are not accustomed to operating the automatic analyzer 1 can replace them without hesitation, further improving the usability.
