Description

Automatic analyzer and analysis result display method

[0001] The present invention relates to an automatic analyzer and a method for displaying analysis results.

[0002] An automated analyzer that automatically performs quantitative and qualitative analysis of biological samples such as blood and urine (hereinafter referred to as "specimens") executes an analysis operation according to analysis parameters that are preset for the specified item when an analysis request for the specified item is received. For example, Patent Document 1 describes an automated analyzer that classifies analysis parameters into fixed parameters and variable parameters and controls analysis operations based on these parameters in order to set analysis parameters that reflect the characteristics of reagents that vary for each reagent lot. Generally, analysis parameters are version-managed, and the versions are updated according to the test subject and test status.

[0003] JP 2012-107985 A

[0004] In conventional automatic analyzers including the technology of Patent Document 1, if analysis parameters are updated during an analysis operation, the analysis results cannot be linked to the parameters applied to the analysis, so the timing of updating analysis parameters is restricted to when the analyzer is in standby mode. For this reason, when a user wants to update analysis parameters, they must first put the analyzer into standby mode, which requires a wait time before the analyzer can be re-enabled, potentially resulting in a decrease in processing power.

[0005] An object of the present invention is to provide an automatic analyzer with high processing capacity by enabling analysis parameters to be updated without the need for a standby state.

[0006] In order to achieve the above-mentioned object, the present invention provides an automatic analyzer comprising an analysis module that analyzes a sample, a memory unit that stores the analysis results of the analysis module, a display unit that displays the analysis results stored in the memory unit, and a control unit that controls the analysis module, the memory unit, and the display unit, wherein the memory unit stores the analysis results in association with the analysis parameters applied to the analysis, and the display unit displays the version of the analysis parameters for each analysis result.

[0007] According to the present invention, an automatic analyzer with high processing capacity can be provided by making it possible to update analysis parameters without going into standby mode.

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

[0010] First, the configuration of the automatic analyzer will be described with reference to Figures 1 and 2. Figure 1 is a front view showing the appearance of the overall configuration of the automatic analyzer, and Figure 2 is a top view showing a schematic of the overall configuration of the automatic analyzer. The automatic analyzer 100 of this embodiment includes a sampler module 200, analysis modules 107 and 207, and a control device 300.

[0011] The sampler module 200 is a module that transports sample racks to be loaded into the automatic analyzer 100 between the analysis modules 107 and 207. The sampler module 200 also includes a transport line 104, an emergency sample rack loading section 112, a sample rack supply section 102, a sample rack storage section 103, an emergency sample rack waiting area 113, a sample identification device 105, a rack rotor 106, etc.

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

[0013] Here, each component of the sampler module 200 will be described in detail. First, the transport line 104 transports the sample rack 101 and the emergency sample rack 101A back and forth, and is, for example, a belt conveyor-type transport mechanism. The transport line 104 may also use a mechanism in which a protruding structure driven along the transport line 104 fits into a recess pre-formed in the sample rack for transport. Next, the emergency sample rack input unit 112 is provided adjacent to the transport line 104 and is an area for inputting the emergency sample rack 101A. The sample rack supply unit 102 is provided adjacent to the transport line 104, closer to one end of the transport line 104 than the emergency sample rack input unit 112, and is an area for supplying normal sample racks 101. The sample rack storage unit 103 is provided adjacent to the transport line 104, closer to one end of the transport line 104 than the sample rack supply unit 102, and is an area for storing the sample rack 101. The emergency sample rack waiting area 113 is provided on the transport line 104 on the other end side of the transport line 104 from the sample rack storage unit 103, and is an area for temporarily waiting the emergency sample rack 101A. The sample identification device 105 is a mechanism that reads identification media such as RFIDs or barcodes (not shown) provided on the sample rack 101, the emergency sample rack 101A, and the sample containers, and identifies analysis request information related to the transported samples.

[0014] The rack rotor 106 is disposed at one end of the transport line 104. The rack rotor 106 has slots 106a and 106b on which the sample racks 101 and the like can be mounted, and is a mechanism for transferring the sample racks 101 and the like between one end of the transport line 104 and one end of the dispensing lines 109 and 209 of the analysis modules 107 and 207. The rack rotor 106 is configured to rotate clockwise and counterclockwise. The rotation of the rack rotor 106 is controlled so that the sample racks 101 start processing in the order in which they are loaded, or, when a high-priority emergency sample rack 101A is loaded, it starts processing before the normal sample racks 101.

[0015] The analysis modules 107 and 207 are units that perform qualitative and quantitative analysis by sampling (dispensing) samples from samples contained in sample containers mounted on a sample rack. Each analysis module 107 and 207 includes a dispensing line 109 and 209, a sample identification device 110 and 210, a reaction disk 118 and 218, a sample dispensing mechanism 108 and 208, a reagent disk 119 and 219, a reagent dispensing mechanism 120 and 220, a measuring unit (not shown), and the like.

[0016] The dispensing lines 109, 209 are equipped with a reciprocating transport mechanism that pulls in sample racks from the sampler module 200 to the analysis modules 107, 207 and delivers sample racks from the analysis modules 107, 207 to the sampler module 200. While Fig. 2 shows an example of a belt conveyor-type transport mechanism for the dispensing lines 109, 209, it is also possible to use a mechanism in which a protruding structure driven along the dispensing lines 109, 209 is fitted into a recess provided in advance in the sample rack for transport.

[0017] The sample identification devices 110, 210 are mechanisms that read identification media such as RFIDs or barcodes (not shown) attached to the sample rack 101, urgent sample rack 101A, and sample containers to identify analysis request information related to the transported samples. The sample dispensing mechanisms 108, 208 are mechanisms that dispense samples from sample containers in sample racks transported to dispensing positions on the dispensing lines 109, 209 into reaction containers on the reaction disks 118, 218. The reagent dispensing mechanisms 120, 220 are mechanisms that dispense reagents contained in reagent containers on the reagent disks 119, 219 into reaction containers on the reaction disks 118, 218. The measurement units are mechanisms that perform qualitative and quantitative analysis by measuring the mixture (reaction solution) of sample and reagent dispensed into the reaction containers.

[0018] The test purpose (test items) and processing capacity of each analysis module are different; for example, analysis module 107 is assumed to be a unit for biochemical testing, and analysis module 207 is assumed to be a unit for immunological testing. In addition, a unit for measuring electrolyte concentration can be provided in analysis module 107, and a unit for blood coagulation analysis can be appropriately placed in each module depending on the specification environment. Furthermore, although the number of analysis modules is two in this embodiment, it may be three or more.

[0019] The control device 300 is a computer that controls the overall operation of the automated analyzer 100, including the components of the analysis modules 107, 207 and the sampler module 200, and is equipped with a control unit 114, a display unit 116, an input unit 117, a memory unit 115, and the like. The control unit 114 is composed of a CPU, memory, and the like. The display unit 116 is a display device such as a liquid crystal display that displays various setting screens including those for setting analysis parameters, a request screen for analysis items, a confirmation screen for analysis results, maintenance information, and the like. The input unit 117 is, for example, a keyboard or mouse, and accepts input from the user. The memory unit 115 stores information such as the analysis results of each analysis module and the contents of various settings.

[0020] Next, the overall flow of the analytical operation in the automatic analyzer having the above-described configuration will be described with reference to Fig. 3. Fig. 3 is a flowchart showing the overall analytical 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 automated analyzer is in a standby state (step S302). If it is determined to be in a standby state, the control unit 114 executes preparatory operations for the analysis, such as registering reagents and checking sensors (step S305).

[0022] On the other hand, if it is determined in step S302 that the device is not in the standby state, the control unit 114 determines whether the device is in a state where analysis is possible (step S303). If the device is currently analyzing another sample or is in the rack reception state, it is determined that the device is in a state where analysis is possible, and analysis of the sample for which analysis was requested is initiated (step S308). However, if the device is in the startup operation or maintenance mode, it is determined that dispensing is not possible, and the analysis request is rejected (step S304). Note that the rack reception state is a state in which analysis can be initiated in a shorter time than the standby state. In the rack reception state, for example, the dispensing mechanism stops as in the standby state, but the reaction disk does not stop, unlike in the standby state. Therefore, when an analysis request is received from a user, the analysis can be initiated without performing the preparatory operations for analysis.

[0023] Furthermore, while the analysis preparation operation is being performed in step S305, the control unit 114 checks the state of the reagent and the status of the sensor, and continuously determines whether the analysis is possible (step S306). If the remaining amount of reagent is insufficient, it is determined that the analysis is not possible, and the analysis preparation is stopped (step S307). On the other hand, if the analysis preparation operation is completed while the analysis is still possible, the control unit 114 starts the analysis (step S308).

[0024] During the analysis, the control unit 114 continues to determine whether there are any abnormalities in the analysis, such as by checking the remaining amount of reagent (step S309), and if it determines that there are any abnormalities, it stops the analysis (step S310). If the analysis is completed without any abnormalities (step S311), the control unit 114 determines whether the rack reception mode setting is valid (step S312). If it is determined that the rack reception mode is valid, the automatic analyzer transitions to a rack reception state (step S314) and continues the rack reception state for a time period previously specified by the user. On the other hand, if it is determined that the rack reception mode is invalid, the automatic analyzer performs an operation after the analysis is completed (step S313) and then transitions to a standby state.

[0025] 3, the user can forcibly stop the analysis operation and rack reception state and transition the automatic analyzer to a standby state by operating the stop button displayed on the display unit using the input unit. However, if the automatic analyzer is to perform analysis again after transitioning to the standby state, it must again perform the operations from step S305 onwards.

[0026] Here, each analysis module of the automated analyzer performs analysis according to analysis parameters preset by the control device 300. These analysis parameters not only need to be updated (corrected) when there is a defect, but are also preferably updated to more appropriate parameters depending on the analysis situation. Below, specific processing from when the control device 300 receives an instruction to update the analysis parameters from the user to when the updated analysis parameters are applied to the analysis will be described. First, processing in a conventional automated analyzer will be described as a comparative example, and then processing in the automated analyzer according to the embodiment will be described.

[0027] Comparative Example FIG. 4 is a flowchart showing the process of updating analysis parameters in a conventional automatic analyzer.

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

[0029] If it is determined in step S403 that the analyzer is in the standby state, the control unit reads the setting contents of the analysis parameters for which the update instruction was received (step S405), and determines whether there are any problems when applying the update based on the read setting contents (step S406). If it is determined that there is a problem, such as when the amount of reagent dispensed is outside the measurable range, the control unit outputs a response to the display unit that the analysis parameters cannot be updated (step S407), and interrupts the update process.

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

[0031] As described above, the automated analyzer according to the comparative example cannot update analysis parameters unless it is in standby mode. Therefore, if the automated analyzer is in the middle of an analysis or rack reception mode when a user requests an update of analysis parameters, the user must force the automated analyzer into standby mode by operating the stop button. However, when the automated analyzer performs an analysis again after switching to standby mode, as described above, the automated analyzer must perform the preparatory operations of step S305, etc., which takes time before the analysis can be started again.

[0032] Some analysis parameters, even if updated, have little effect on the analysis results. In such cases, it is considered that the automated analyzer does not necessarily need to immediately transition to a standby state even during an analysis. However, if the automated analyzer according to the comparative example were to be able to update analysis parameters during an analysis, the user would not be able to understand the association between the analysis results and the version of the analysis parameters applied to the analysis. This is because the automated analyzer according to the comparative example records information about the analysis parameters in a memory unit, but does not display the information about the analysis parameters on the analysis result confirmation screen. While it is possible to roughly estimate which version of the analysis parameters was applied to which analysis by referring to the date and time the analysis parameters were updated, it is difficult to determine the exact version. In particular, if the analysis parameters are updated while the automated analyzer is performing an analysis, it is difficult to estimate the version of the analysis parameters applied to the analysis.

[0033] An automatic analyzer according to a first embodiment will be described with reference to FIGS.

[0034] 5 is a diagram showing an example of an analysis result confirmation screen and a linked database stored in a 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 linked database 512 in the storage unit 115.

[0035] When analysis results are output, related information is cumulatively recorded in the linked database 512, regardless of whether the analysis results are successful or unsuccessful. The linked database 512 stores specimen information 513 and analysis result information 514, and also stores analysis parameter information 515 (e.g., the version of the analysis parameters) linked to this information. The specimen information 513 includes, for example, a specimen ID 502, a rack ID 503, and a specimen type 504. The analysis result information 514 includes, for example, an analysis item name 505, a unit 506, a result 507 (measured value), a data alarm result 508, an analysis module used 509, and an 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 linked database 512 and is managed as cumulatively recorded information.

[0036] Information read from the linked database 512 is output to the analysis result screen 501. A list of samples that have been analyzed in the past is displayed in the sample information 513 column of the analysis result screen 501. When a specific sample is selected by the user from the sample information 513 column, the display unit displays not only analysis result information 514 corresponding to that sample, but also analysis parameter information 515 applied to the analysis for each analysis result. Note that Figure 5 shows a state in which AAAAA is selected as the sample ID, and all analysis results performed on that sample and the versions of the analysis parameters for each analysis are displayed.

[0037] In this way, the analysis result screen 501 displays the version of the analysis parameters for each analysis result, so even if the analysis parameters are updated during the analysis operation, the user can understand the association between the analysis results and the analysis parameters applied to the analysis.

[0038] FIG. 6 shows an example of an analysis parameter setting screen. The analysis parameter screen 601 allows the user to confirm and update the analysis parameter settings. 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 in an analysis item list 604. Furthermore, when the user selects a specific analysis item from the analysis item list 604, the display unit displays detailed information about the analysis parameters currently set for that analysis item. The detailed analysis parameter information includes, for example, basic information such as code numbers, units, and technical limits, as well as reagent-related information such as the amount of reagent dispensed and diluted during analysis and special reagents used. If the user wishes to update the analysis parameters, an update button 605 is operated using the input unit.

[0039] When the update button 605 is operated on the analysis parameter screen 601 in Fig. 6, the display unit displays an analysis parameter update screen 701 shown in Fig. 7. Fig. 7 is a diagram showing an example of the analysis parameter update screen. When the user selects the version to be applied using the analysis parameter version combo box 702 and operates the overwrite button 703, the analysis parameters are updated.

[0040] FIG. 8 is a flowchart illustrating the analysis parameter update process in the automatic analyzer according to the first embodiment.

[0041] 6 and 7, the control unit receives an instruction to update the analysis parameters (step S801), and determines whether there are any problems with applying the update based on the received settings (step S802). If it determines that there is a problem, such as when the reagent dispensed amount is outside the measurable range, the control unit outputs a response to the display unit indicating that the analysis parameters cannot be updated (step S803), and interrupts the update process.

[0042] If it is determined in step S802 that there is no problem, the control unit does not immediately apply the updated analysis parameters, but continues to apply the current analysis parameters and waits for the analysis parameters to be updated (step S804). Next, the control unit determines whether the state of the automated analyzer has reached the time for calibration (step S805), and continues to apply the current analysis parameters until the time for calibration arrives. When the time for calibration arrives, the control unit applies the updated analysis parameters based on the received settings (step S806).

[0043] As described above, in the first embodiment, the user can instruct the automatic analyzer to update the analysis parameters even when the automatic analyzer is not in standby mode. In other words, since there is no need to immediately transition to standby mode, the waiting time until the automatic analyzer is ready for analysis again is eliminated, thereby improving processing capacity. Furthermore, in the first embodiment, if a user instructs the automatic analyzer to update while the automatic analyzer is performing an analysis or while the automatic analyzer is in a rack reception state, the analysis operation can be continued until the timing of the next calibration while applying the analysis parameters of the pre-update version. In particular, in the case of analysis parameters that have little impact on the analysis results, a certain level of accuracy can be ensured even for analysis results based on the analysis parameters before the update.

[0044] An automatic analyzer according to a second embodiment will be described with reference to Fig. 9. The following description will focus on differences from the first embodiment.

[0045] 9 is a diagram illustrating an example of a version-specific parameter information screen and an integrated database stored in a storage unit in an automatic analyzer according to Example 2. The automatic analyzer according to Example 2 displays a version-specific parameter information screen 901 on the display unit based on information stored in an integrated database 909 in the storage unit 115.

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

[0047] The version-specific parameter information screen 901 displays analytical parameter settings and analytical results for each version, side by side, as information read from the integrated database 909. The analytical parameter settings include, for example, version 903, units 904, technical limits 905, and dilution amount 906. The analytical results include, for example, data alarms 907 and measured values ​​908.

[0048] Here, the version-specific parameter information screen 901 displays not only the analytical parameter settings of the actually applied version and the analytical results actually obtained, but also the analytical parameter settings of other versions and the analytical results predicted if those analytical parameters were applied. The prediction of the analytical results is performed by the control unit using actual analytical results stored in the integrated database 909. The predicted results may be associated with the actual analytical results and stored in the integrated database 909. Note that FIG. 9 shows a state in which an ASTP analysis item for a sample with a sample ID of AAAAA is selected, and the version-specific parameter information screen 901 displays not only the data of the actually applied version "101-1" but also data of other versions.

[0049] In this way, in Example 2, the results when the version is updated and when the version is not updated can be compared, allowing the user to visually confirm the effect of the version update. In addition, the predicted values ​​when other versions that are not actually applied are applied are also displayed, which can serve as a guide for finding an effective version when the actual analysis results are unexpected.

[0050] An automatic analyzer according to a third embodiment will be described with reference to Figures 10 to 12. The following description will focus on differences from the first embodiment.

[0051] In the first embodiment described above, even when an instruction to update the analysis parameters was received, the current analysis parameters continued to be applied, and the updated analysis parameters were applied at the timing of calibration. However, in the case of analysis parameters that have a significant impact on the analysis results, the accuracy of the analysis results cannot be guaranteed unless the analysis parameters are updated and calibration is performed immediately. In particular, in the case of an immunoassay analysis item, when an instruction to update the analysis parameters is received from the user, it is desirable that the control unit immediately applies the updated analysis parameters and not perform general analysis or quality control for that analysis item until the next calibration is performed. For this reason, in the third embodiment, the user can select the timing of application of the updated analysis parameters via the input unit.

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

[0053] When the "immediately after manual update" radio button 1002 is selected on the application timing setting screen 1001, a mode is set in which an update is immediately applied when an instruction to update an analysis parameter is received. When the "automatic update (all items)" radio button 1003 is selected on the application timing setting screen 1001, a mode is set in which an update is applied from the next calibration onwards, regardless of the instruction to update any analysis parameter.

[0054] When the item selection button 1005 is operated with the automatic update (specific item) radio button 1004 selected on the application timing setting screen 1001, the display unit displays the application timing optimization target item screen 1101 shown in Fig. 11. Fig. 11 is a diagram showing an example of a setting screen for specifying analysis items to be subject to automatic update. Of the analysis item list 1102, analysis items for which the application switch checkbox 1103 is enabled are set to automatic update, that is, a mode in which the update is applied from the next calibration onwards even if an instruction to update the analysis parameters is received.

[0055] 12 is a flowchart showing the analysis parameter update process in the automatic analyzer according to Example 3. Here, a case will be described in which the automatic analyzer receives an instruction to update the analysis parameters during an analysis operation or while in a rack reception state.

[0056] When the control unit receives an instruction to update the analysis parameters (step S1201), it determines whether the setting "immediately after manual update" is valid (step S1202). If it is determined that the setting is valid, the control unit immediately applies the new version after the update from the immediately following analysis (step S1203).

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

[0058] If it is determined in step S1204 that the setting is invalid, the control unit determines whether the item is an optimization target item for which "automatic update" is set (step S1206). If it is determined that the item is an optimization target item, the control unit retains the current version of the analysis parameters and applies the updated new version at the timing of the next calibration (step S1207).

[0059] If it is determined in step S1206 that the item is not an optimization target item, the control unit immediately applies the new version after the update (step S1208).

[0060] In this way, in the third embodiment, the application timing can be changed depending on the analysis item, so that it is possible to ensure the accuracy of the analysis results and improve the processing capacity at the same time.

[0061] The present invention is not limited to the above-described embodiments and includes various modifications. For example, the above-described embodiments have been described in detail to clearly explain the present invention, and the present invention is not necessarily limited to those including all of the described configurations.
