For example, Patent Document 1 describes an automated analyzer that, in order to set analysis parameters reflecting the characteristics of each reagent batch, classifies the analysis parameters into fixed and variable parameters, and controls the analysis using these parameters.

[0003] Patent Document 1: Japanese Patent Application Laid-Open No. 2012-107985 Summary of the Invention Technical problem to be solved by the invention

[0004] In conventional automatic analyzers, including the technology described in Patent Document 1, updating analysis parameters during analysis, for example, prevents the relationship between the analysis results and the parameters used for analysis. Therefore, the timing for updating analysis parameters is limited to when the device is in standby mode. Consequently, if a user wishes to update analysis parameters, they must first place the device in standby mode, requiring a waiting period before analysis can resume, potentially reducing processing capacity.

[0009] Hereinafter, embodiments of the present invention will be described using the drawings.

[0010] First, use Figure 1 and Figure 2 The structure of the automatic analyzer will be described. Figure 1 This is a front view showing the appearance of the overall structure of the automatic analyzer. Figure 2 1 is a plan view schematically showing the overall structure of the automatic analyzer. The automatic analyzer 100 of this embodiment includes a sampling module 200 , analysis modules 107 and 207 , and a control device 300 .

[0011] The sampling module 200 is a module that transfers sample racks introduced into the automatic analyzer 100 between the analysis modules 107 and 207. The sampling module 200 also includes a conveyor line 104, an emergency sample rack introduction unit 112, a sample rack supply unit 102, a sample rack storage unit 103, an emergency sample rack standby area 113, a sample identification device 105, a rack rotor 106, and the like.

[0012] The specimen rack is equipped with one or more specimen containers containing specimens to be analyzed qualitatively or quantitatively in the analysis modules 107 and 207. The specimen racks include at least a normal specimen rack 101 and an emergency specimen rack 101A. The normal specimen rack 101 is equipped with specimen containers containing specimens to be analyzed with normal priority (normal specimens). The emergency specimen rack 101A is equipped with specimen containers containing specimens with a higher analysis priority than normal specimens (emergency specimens).

[0013] Here, the various components of the sampling module 200 are described in detail. First, the conveyor line 104 is used to transport the specimen rack 101 or the emergency specimen rack 101A back and forth, and is, for example, a conveyor belt-type transport mechanism. Alternatively, the conveyor line 104 may employ a mechanism in which protrusions driven along the conveyor line 104 engage recesses pre-determined on the specimen racks. Next, the emergency specimen rack loading section 112 is provided adjacent to the conveyor line 104 and is an area for loading emergency specimen racks 101A. The specimen rack supply section 102 is provided adjacent to the conveyor line 104, closer to one end of the conveyor line 104 than the emergency specimen rack loading section 112, and is an area for supplying normal specimen racks 101. The specimen rack storage section 103 is provided adjacent to the conveyor line 104, closer to one end of the conveyor line 104 than the specimen rack supply section 102, and is an area for storing specimen racks 101. The emergency specimen rack waiting area 113 is provided on the other end of the conveyor line 104 than the specimen rack storage section 103, and is an area for temporarily holding the emergency specimen racks 101A. The specimen identification device 105 reads identification media (not shown) such as RFID and barcodes provided on the specimen rack 101 , the emergency specimen rack 101A, and the specimen container to identify analysis request information related to the transferred specimen.

[0014] The rack rotor 106 is located at one end of the conveyor line 104. It has slots 106a and 106b for loading sample racks 101 and other items. It serves as a mechanism for transferring sample racks 101 and other items between the end of the conveyor line 104 and the ends of the dispensing lines 109 and 209 of the analysis modules 107 and 207. The rack rotor 106 rotates clockwise and counterclockwise. The rotation of the rack rotor 106 is controlled to process sample racks 101 in the order they are loaded. Alternatively, when a high-priority emergency sample rack 101A is loaded, processing begins before normal sample racks 101.

[0015] The analysis modules 107 and 207 are units that sample (dispense) specimens contained in specimen containers mounted on specimen racks for qualitative and quantitative analysis. These modules include dispensing lines 109 and 209, specimen identification devices 110 and 210, reaction disks 118 and 218, specimen dispensing mechanisms 108 and 208, reagent disks 119 and 219, reagent dispensing mechanisms 120 and 220, and a measuring unit (not shown).

[0016] The dispensing lines 109 and 209 include a transport mechanism capable of reciprocating motions of introducing a specimen rack from the sampling module 200 to the analysis module 107 and 207 and delivering the specimen rack from the analysis module 107 and 207 to the sampling module 200 . Figure 2 Although an example of a conveyor type transport mechanism as the dispensing lines 109 and 209 is shown, a mechanism may be used instead in which a protrusion structure driven along the dispensing lines 109 and 209 is engaged with a recessed portion pre-formed on the specimen holder to perform transport.

[0017] The specimen identification device 110, 210 is a mechanism that reads identification media such as RFID and barcodes (not shown) provided on the specimen rack 101, the emergency specimen rack 101A, and the specimen container to identify analysis request information related to the transferred specimen. The specimen dispensing mechanism 108, 208 is a mechanism that dispenses the specimen from the specimen container of the specimen rack transferred to the dispensing position on the dispensing line 109, 209 into the reaction container of the reaction disk 118, 218. The reagent dispensing mechanism 120, 220 is a mechanism that dispenses the reagent contained in the reagent container on the reagent disk 119, 219 into the reaction container on the reaction disk 118, 218. The measuring unit is a mechanism that measures the mixed solution (reaction solution) of the specimen and reagent dispensed into the reaction container to perform qualitative and quantitative analysis.

[0018] Each analysis module has different inspection objectives (inspection items) and processing capabilities. For example, analysis module 107 is assumed to be a biochemical testing unit, while analysis module 207 is assumed to be an immunoassay unit. Alternatively, an electrolyte concentration measurement unit may be provided within analysis module 107, or a blood coagulation analysis unit may be appropriately configured within each module depending on the specifications and environment. In this embodiment, the number of analysis modules is two, but the number may be three or more.

[0019] The control device 300 includes the components of the analysis modules 107 and 207, as well as the sampling module 200. It is a computer that controls the overall operation of the automatic analyzer 100. In addition to the control unit 114, it also includes a display unit 116, an input unit 117, and a storage unit 115. The control unit 114 is composed of a CPU, memory, and other components. The display unit 116 is a display device such as a liquid crystal display that displays various setting screens, including analysis parameter settings, analysis project request screens, analysis result confirmation screens, and maintenance information. The input unit 117, such as a keyboard or mouse, receives input from the user. The storage unit 115 stores information such as analysis results and various settings in each analysis module.

[0020] Next, use Figure 3 The overall flow of the analysis operation in the automatic analyzer having the above configuration will be described. Figure 3 This is a flowchart showing the overall analysis operation of the automatic analyzer.

[0021] When the control unit 114 receives an analysis request from a user via the input unit 117 (step S301), it determines whether the automatic analyzer is in a standby state (step S302). If it is determined to be in the standby state, the control unit 114 performs analysis preparation operations such as reagent registration and sensor verification (step S305).

[0022] On the other hand, when it is determined in step S302 that the device is not in the standby state, the control unit 114 determines whether it is in a state capable of analysis (step S303). When other specimens are in the process of analysis or in the state of receiving the support, it is determined that it is in a state capable of analysis, and the analysis of the specimen with the analysis request is started (step S308). However, when the device is in the process of starting up or in the process of maintenance execution, it is determined that it is in a state where dispensing is not possible, and the analysis request is abandoned (step S304). The so-called support receiving state refers to a state that can be transferred to the analysis action in a shorter time than the standby state. In the stand receiving state, for example, the dispensing mechanism stops in the same way as the standby state, but unlike the standby state, the reaction disk does not stop. Therefore, when an analysis request is received from the user, the preparation action for the analysis can be omitted and the analysis can be started.

[0023] Furthermore, while the analysis preparation process is being performed in step S305, the control unit 114 also checks the status of the reagents and the status of the sensors, and continues to determine whether the analysis is possible (step S306). If, for example, the reagents are insufficient, the analysis is determined to be impossible, and the analysis preparation process is terminated (step S307). On the other hand, if the analysis preparation process is completed while the analysis is possible, the control unit 114 begins the analysis (step S308).

[0024] During the analysis, the control unit 114 continues to determine whether there is an abnormality in the analysis such as the confirmation of the reagent residue (step S309). If it is determined that there is an abnormality, the analysis is stopped (step S310). If the analysis ends without any abnormality (step S311), the control unit 114 determines whether the setting of the bracket receiving mode is valid (step S312). If it is determined that the bracket receiving mode is valid, the automatic analyzer transfers to the bracket receiving state (step S314) and continues the bracket receiving state for a time pre-specified by the user. On the other hand, if it is determined that the bracket receiving mode is invalid, the automatic analyzer transfers to the standby state after executing the action after the analysis is completed (step S313).

[0025] exist Figure 3 Between steps S305 and S314, the user can use the input unit to operate the stop button displayed on the display unit to forcibly stop the analysis operation and the rack reception state, thereby switching the automatic analyzer to the standby state. However, if the automatic analyzer resumes analysis after switching to the standby state, the steps from step S305 onwards must be repeated.

[0026] Here, each analysis module of the automatic analyzer performs analysis based on analysis parameters pre-set by the control device 300. If these analysis parameters are incomplete, they must not only be updated (corrected), but also preferably updated to more appropriate parameters based on the analysis situation. The following describes the specific processing by the control device 300 from receiving a user's instruction to update analysis parameters to applying the updated analysis parameters to the analysis. First, as a comparative example, the processing in a conventional automatic analyzer will be described, followed by the processing in the automatic analyzer according to the embodiment.

[0027] (Comparative Example) Figure 4 This is a flowchart showing the update process of analysis parameters in a conventional automatic analyzer.

[0028] When the control unit receives an instruction to update analysis parameters (step S401), it checks the status of the automatic analyzer (step S402). Next, the control unit determines whether the automatic analyzer is in a standby state (step S403). If it is not in the standby state, the control unit causes the display unit to display a response indicating that the analysis parameters cannot be updated (step S404), and the update process is interrupted.

[0029] If the system is determined to be in the standby state in step S403, the control unit reads the settings of the analysis parameters for which an update instruction has been received (step S405), applies the update based on the read settings, and determines whether there is no problem (step S406). If a problem is determined, such as when the reagent aliquot volume is outside the measurable range, the control unit causes the display unit to output a response indicating that the analysis parameters cannot be updated (step S407), and interrupts the update process.

[0030] If it is determined that there is no problem in step S406, the control unit immediately updates the analysis parameters (step S408) and then executes the calibration, accuracy control, and general analysis processes. The order of steps S403 and S406 may be reversed.

[0031] Therefore, in the automatic analyzer of the comparative example, analysis parameters cannot be updated unless the analyzer is in the standby state. Therefore, if a user wishes to update analysis parameters while the automatic analyzer is in the process of performing an analysis or receiving a rack, the user must force the analyzer to switch to the standby state by pressing the stop button. However, when the automatic analyzer resumes analysis after switching to the standby state, as described above, it must perform the preparatory steps in step S305, which takes time before resuming analysis.

[0032] Here, depending on the analysis parameters, there are also analysis parameters whose impact on the analysis results is small even if they are updated. In this case, it can be imagined that the automatic analysis device does not necessarily have to be immediately transferred to the standby state even during the analysis action. However, in the automatic analysis device involved in the comparative example, assuming that the analysis parameters can also be updated during the analysis action, the user cannot grasp the association between the analysis result and the version of the analysis parameter applied to the analysis. The reason is that in the automatic analysis device involved in the comparative example, the information of the analysis parameters is also recorded in the storage unit, but the information of the analysis parameters is not displayed on the confirmation screen of the analysis result. By referring to the date and time when the analysis parameters were updated, it is possible to roughly infer which version of the analysis parameters was applied to which analysis, but it is difficult to determine. In particular, when the automatic analysis device updates the analysis parameters during the analysis action, it is also difficult to infer the version of the analysis parameters applied to the analysis. Example 1

[0033] based on Figures 5 to 8 The automatic analyzer according to Example 1 will be described.

[0034] Figure 5 This figure shows an example of an analysis result confirmation screen and a relational database stored in the storage unit in the automatic analyzer according to Example 1. The automatic analyzer according to Example 1 displays an analysis result screen 501 (analysis result confirmation screen) on the display unit based on information stored in the relational database 512 in the storage unit 115.

[0035] When outputting analysis results, regardless of whether the analysis results are successful or failed, the relevant information is accumulated and recorded in a relational database 512. The relational database 512 stores specimen information 513 and analysis result information 514, and also stores analysis parameter information 515 (e.g., analysis parameter version) in association with this information. The specimen information 513 includes, for example, the specimen ID 502, the rack ID 503, and the specimen type 504. The analysis result information 514 includes, for example, the analysis item name 505, the unit 506, the result 507 (measured value), the data alarm result 508, the analysis module used 509, and the analysis status 510. Even if the user deletes the analysis result information 514 or the analysis parameter information 515, it is not deleted from the relational database 512 and is managed as accumulated and recorded information.

[0036] The information read from the relational database 512 is output to the analysis result screen 501. A list of previously analyzed specimens is displayed in the specimen information 513 column on the analysis result screen 501. When the user selects a specific specimen from the specimen information 513 column, the display unit displays not only the analysis result information 514 corresponding to the specimen, but also analysis parameter information 515 applied to the analysis for each analysis result. Figure 5 This indicates that AAAAA is selected as the sample ID, and all analysis results for the sample and the versions of the analysis parameters in each analysis are displayed.

[0037] Thus, the analysis parameter version is displayed for each analysis result on the analysis result screen 501 . Therefore, even when the analysis parameter is updated during the analysis operation, the user can understand the relationship between the analysis result and the analysis parameter used for the analysis.

[0038] Figure 66 is a diagram showing an example of a setting screen for analysis parameters. In the analysis parameter screen 601, the setting contents of the analysis parameters can be confirmed or updated. When the user selects a module type using the analysis module type selection combo box 602, the display unit displays all analysis items corresponding to the selected analysis module on the analysis item list 604. In addition, when the user selects a specified analysis item in the analysis item list 604, the display unit displays detailed information on the analysis parameters currently set for the analysis item. The detailed information on the analysis parameters includes, for example, basic information such as code number, unit system, technical restrictions, and reagent-related information such as the reagent injection amount, dilution amount, and special reagents used during analysis. When the user wishes to update the analysis parameters, the input unit operates the update button 605.

[0039] when Figure 6 When the update button 605 is operated in the analysis parameter screen 601 of Figure 7 Analysis parameter update screen 701 is shown. Figure 7 702 is a diagram showing an example of an analysis parameter update screen. When the user selects an application version using the analysis parameter version combo box 702 and operates the overwrite button 703, the analysis parameters are updated.

[0040] Figure 8 This is a flowchart showing the update process of analysis parameters in the automatic analyzer according to the first embodiment.

[0041] When the control unit passes Figure 6 and Figure 7 When an instruction to update analysis parameters is received on the screen shown (step S801), the update is applied based on the received settings and a determination is made as to whether there is a problem (step S802). If a problem is determined, such as when the reagent aliquot volume is outside the measurable range, the control unit causes the display unit to output a response indicating that the analysis parameters cannot be updated (step S803), and the update process is interrupted.

[0042] If, in step S802, the control unit determines that there are no problems, the analysis parameter update is not immediately applied, but the current analysis parameters are continued to be applied, pending an analysis parameter update (step S804). Next, the control unit determines whether the automatic analyzer has reached the calibration time (step S805), and the current analysis parameters are continued to be applied until the calibration time is reached. If the calibration time is reached, the control unit applies the analysis parameter update based on the received settings (step S806).

[0043] Thus, in Example 1, the user can instruct the update of the analysis parameters even if the automatic analyzer is not in the standby state. That is, since there is no need to immediately switch to the standby state, the waiting time before becoming capable of analysis again can be eliminated, thereby improving the processing capacity. In addition, in Example 1, when the automatic analyzer is in the analysis action or the bracket receiving state and the user issues an update instruction, the analysis parameters of the version before the update can be directly applied to continue the analysis action, etc., until the timing of the next calibration. In particular, in the case of analysis parameters that have a smaller impact on the analysis results, a certain degree of accuracy can be guaranteed even for analysis results based on the analysis parameters before the update. Example 2

[0044] based on Figure 9 The automatic analyzer according to Example 2 will be described. Hereinafter, the differences from Example 1 will be focused on for description.

[0045] Figure 9 This figure shows an example of a parameter information screen displayed by version and an integrated database stored in the storage unit in the automatic analysis device according to Example 2. The automatic analysis device according to Example 2 displays a parameter information screen displayed by version 901 on the display unit based on information stored in the integrated database 909 in the storage unit 115.

[0046] When analysis results are output, similar to the relational database of Example 1, regardless of whether the analysis result is successful or unsuccessful, relevant information is accumulated and recorded in the integrated database 909. The integrated database 909 stores sample information 910, analysis result information 911, and analysis parameter information 912 in an integrated form.

[0047] On the version-specific parameter information screen 901, analysis parameter settings and analysis results are displayed side by side for each version, as information read from the integrated database 909. Analysis parameter settings include, for example, version 903, unit 904, technical limit 905, and dilution amount 906. Analysis results include, for example, data alarm 907 and measured value 908.

[0048] Here, the version-specific parameter information screen 901 displays not only the settings of the analysis parameters of the version actually applied and the actual analysis results, but also the settings of the analysis parameters of other versions and the predicted analysis results if the analysis parameters were applied. The control unit uses the actual analysis results stored in the integrated database 909 to predict the analysis results. The predicted results can be stored in the integrated database 909 in association with the actual analysis results. Figure 9, the state in which the ASTP analysis item is selected for the sample with the sample ID AAAAA and not only the data of the actually applied version "101-1" but also the data of other versions is displayed on the version-specific parameter information screen 901 is shown.

[0049] Thus, in Example 2, the updated version can be compared with the non-updated version, allowing the user to visually confirm the effect of the version update. Furthermore, since the predicted value is also displayed if a different version that was not actually applied is applied, this can serve as a sign that a valid version has been found even if the actual analysis results are unexpected. Example 3

[0050] based on Figures 10 to 12 The automatic analyzer according to Example 3 will be described. Hereinafter, the differences from Example 1 will be focused on for description.

[0051] In the first embodiment described above, even if an instruction to update the analysis parameters is received, the current analysis parameters continue to be applied, and the analysis parameter updates are applied at the calibration timing. However, in the case of analysis parameters that significantly affect the analysis results, the analysis parameter update and calibration must be performed immediately to ensure the accuracy of the analysis results. In particular, for analysis items related to immunoassays, upon receiving an instruction from the user to update analysis parameters, the control unit preferably immediately applies the updated analysis parameters, and does not perform general analysis or accuracy management related to the analysis item until the next calibration. Therefore, in Example 3, the user can select the timing for applying the updated analysis parameters via the input unit.

[0052] Figure 10 FIG. 1 is a diagram showing an example of a setting screen for applying updated analysis parameters.

[0053] In the application timing setting screen 1001, if the "Immediately after manual update" radio button 1002 is selected, a mode is set to apply the update immediately when an update instruction for an analysis parameter is received. If the "Automatic update (all items)" radio button 1003 is selected in the application timing setting screen 1001, a mode is set to apply the update after the next calibration, regardless of which analysis parameter an update instruction is received.

[0054] In the application timing setting screen 1001, when the automatic update (specific item) radio button 1004 is selected, the display unit displays Figure 11 The application timing optimization target item screen 1101 is shown. Figure 11This figure shows an example of a setting screen for specifying analysis items to be automatically updated. In the analysis item list 1102, analysis items with an enabled application switch checkbox 1103 are set to automatic update, that is, even if an update instruction for analysis parameters is received, the update is applied after the next calibration.

[0055] Figure 12 This is a flowchart showing the update process of analysis parameters in the automatic analyzer according to Example 3. Here, a case where the automatic analyzer receives an instruction to update analysis parameters during analysis operation or in a rack receiving state will be described.

[0056] When the control unit receives an update instruction for analysis parameters (step S1201), it determines whether the "immediately after manual update" setting is valid (step S1202). If the setting is valid, the control unit immediately applies the updated new version based on the subsequent analysis (step S1203).

[0057] If the setting is determined to be invalid in step S1202, the control unit determines whether the "Automatic Update (All Items)" setting is valid (step S1204). If the setting is valid, the control unit continues the analysis operation or the rack reception status while maintaining the current analysis parameter version, and applies the updated version at the next calibration (step S1205).

[0058] If the setting is determined to be invalid in step S1204, the control unit determines whether the project is an optimization target with "auto update" set (step S1206). If it is determined to be an optimization target, the control unit retains the current version of the analysis parameters and applies the updated version at the next calibration (step S1207).

[0059] In step S1206 , when it is determined that the project is not an optimization target project, the control unit immediately applies the updated new version (step S1208 ).

[0060] Thus, in the third embodiment, the application timing can be changed according to the analysis item, so it is possible to achieve both guarantee of the accuracy of the analysis result and improvement of the processing capacity.

[0061] The present invention is not limited to the above-described embodiments but also includes various variations.
