JP7342122B2 - Automatic analyzer and display method of automatic analyzer display device - Google Patents

Description

The present invention relates to an automatic analyzer that analyzes biological samples (hereinafter referred to as specimens) such as blood and urine, and a display method for a display device of the automatic analyzer.

For the purpose of suppressing a decrease in analysis efficiency, Patent Document 1 describes an automatic analyzer having an analysis unit that measures the components of the sample by mixing a reagent with the sample and analyzing the mixture. For each sample, multiple judgment items are judged to determine whether there is any risk of abnormalities occurring in the analysis results, and based on the judgment results, the analysis units and analysis items related to the analysis of the sample are masked (temporarily stopped). It is described that the judgment items that caused the masking are stored in a storage device, and the judgment items that caused the masking are displayed on a display device.

Japanese Patent Application Publication No. 2013-140103

A pause (hereinafter referred to as mask) function is known as one of the functions of automatic analyzers used in clinical testing sites for qualitative and quantitative analysis of specimens. This mask function is a function that temporarily stops measurement of analysis items containing specific components.

Furthermore, Patent Document 1 discloses that, as a function of displaying the masking factors after the analysis results, it is possible to transition from the analysis result screen to a screen displaying the masking factors and solutions.

This mask function is primarily a function to maintain reliability of analysis results.

For example, in an automatic analyzer that has multiple analysis units, if the analysis results become unstable, you can mask the specific analysis unit that caused the instability and adjust the dispensing mechanism or the reaction mechanism. Maintenance such as cleaning can be performed.

In addition, if there is a shortage of reagents or the analysis result of a calibration substance shows an abnormal value, the execution of the related analysis items can be masked, and the reagent can be replaced or the calibration substance remeasured during that time. It is also known to resume analysis of related items after the results have stabilized.

However, the masking factor confirmation means described in Patent Document 1 is a function in which the masking factor is displayed after the analysis results are obtained. For this reason, it has become clear that if the mask is already masked before analysis, the user will not be able to understand the cause of the mask or how to solve it, and there is room for improvement.

Furthermore, it has become clear that there is room for improvement since the technique described in Patent Document 1 may result in unnecessary analysis. In other words, if an analysis is started without realizing that the analysis cannot be performed, reagents and other materials are wasted due to preparation before analysis, and the user has to backtrack, so there is room to solve these wastes. It became clear that

The present invention provides an automatic analyzer and automatic analyzer that can display mask status and factors in a list even before analysis, and can suppress a decrease in analysis efficiency and an increase in running costs compared to conventional methods. A display method for a display device of an apparatus is provided.

The present invention includes a plurality of means for solving the above problems, and one example thereof is an automatic analyzer that analyzes a specimen, including at least one analysis section that analyzes the specimen; a storage unit that stores the mask status and its factors set for each analysis item of the sample in the analysis unit to maintain reliability of the analysis result of the sample; and a storage unit that controls the operation of the analysis unit; a control unit that processes instructions from a user; and a display device that displays information regarding the automatic analysis device; The present invention is characterized in that a list screen is displayed on the display device in which masking statuses of whether or not each of the plurality of masking factors is masked at that timing are listed for each analysis item.

According to the present invention, the mask status and factors can be displayed in a list even before analysis, and it is possible to suppress a decrease in analysis efficiency and an increase in running costs compared to the conventional method. Problems, configurations, and effects other than those described above will be made clear by the description of the following examples.

<Example 1>
Embodiment 1 of the automatic analyzer and the display method of the display device of the automatic analyzer according to the present invention will be described with reference to FIGS. 1 to 6.

First, an example of the overall configuration of an automatic analyzer will be described using FIG. 1. FIG. 1 is a diagram schematically showing the overall configuration of an automatic analyzer according to this embodiment.

In FIG. 1, a module type automatic analyzer 100 shown as an example in this embodiment includes a plurality of (two in this embodiment) analysis modules 107, 207 and samples to be analyzed in these analysis modules 107, 207. The automatic analyzer 100 is generally configured of a transport module 200 that transports a sample rack 101 loaded with one or more sample containers containing a sample container, and a control device 300 that controls the overall operation of the automatic analyzer 100.

The sample rack 101 is loaded with one or more sample containers containing samples to be subjected to qualitative and quantitative analysis in the analysis modules 107 and 207.

The transport module 200 is a module that transports the sample rack 101 loaded into the automatic analyzer 100 between the analysis modules 107 and 207, and includes the sample rack supply section 102, the emergency sample rack input section 112, the transport line 104, and the emergency sample rack input section 112. It includes a sample rack standby area 113, a sample identification device 105, a rack rotor 106, a sample rack storage section 103, and the like.

The transport line 104 is, for example, a belt conveyor type transport mechanism that reciprocates the sample rack 101 and the emergency sample rack 101A.

The emergency sample rack loading section 112 is provided adjacent to the transport line 104, and is an area for loading the emergency sample rack 101A.

The emergency sample rack standby area 113 is provided on the transport line 104, and is an area for temporarily making the emergency sample rack 101A stand by.

The sample identification device 105 uses RFID and bar information provided on the sample rack 101 and sample containers to inquire about analysis request information regarding samples contained in sample containers mounted on the sample rack 101 transported on the transport line 104. This is a mechanism for reading and identifying an identification medium (not shown) such as a code.

The rack rotor 106 is arranged at one end of the conveyance line 104. This rack rotor 106 has one or more slots 106a and 106b in which the sample rack 101 and the like can be mounted, and one end of the transport line 104 and one end of the dispensing lines 109 and 209 of the analysis modules 107 and 207, respectively. This is a mechanism for transferring sample racks 101 and the like to and from.

For example, the rack rotor 106 has a structure that rotates clockwise and counterclockwise, so that processing is started in the order in which sample racks 101 are loaded, or if a sample rack 101 with a high priority is loaded. In this case, the rotating operation is appropriately controlled so that processing can be started before the sample rack 101 loaded first.

The analysis modules 107 and 207 are units that perform qualitative and quantitative analysis by sampling (dispensing) samples contained in sample containers mounted on the sample rack 101, and are connected to dispensing lines 109 and 209, respectively. , a sample identification device 110, 210, a reaction disk 118, 218, a sample dispensing mechanism 108, 208, a reagent disk 119, 219, a reagent dispensing mechanism 120, 220, a measuring section (not shown), and the like.

The analysis module 107 further includes an electrolyte measuring section 121.

The dispensing lines 109, 209 are reciprocating transport mechanisms that draw the sample rack 101 from the transport module 200 to the analysis modules 107, 207 and deliver the sample rack 101 from the analysis module 107, 207 to the transport module 200. has been adopted. For example, a belt conveyor type mechanism.

Note that although a belt conveyor type transport mechanism is used as the dispensing lines 109 and 209, the protruding structures that are driven along the dispensing lines 109 and 209 are provided in advance on the sample rack 101. It is possible to adopt a configuration in which the device is transported while being fitted into a recess. Such a configuration is similarly applicable to the conveyance line 104.

The sample identification devices 110 and 210 are provided adjacent to the other ends of the dispensing lines 109 and 209, and collect analysis request information for samples stored in the sample racks 101 carried into the dispensing lines 109 and 209. This is a mechanism that reads and identifies identification media (not shown) such as RFID and barcodes provided on the sample rack 101 and sample containers.

The sample dispensing mechanisms 108 and 208 are mechanisms that dispense samples from the sample containers of the sample rack 101 transported to the dispensing positions on the dispensing lines 109 and 209 to the reaction containers of the reaction disks 118 and 218.

The reagent dispensing mechanisms 120 and 220 are mechanisms for dispensing the reagents contained in the reagent containers of the reagent disks 119 and 219 into the reaction containers of the reaction disks 118 and 218.

The measurement unit is a mechanism that performs qualitative and quantitative analysis by measuring a mixed solution (reaction solution) of a sample and reagent dispensed into a reaction container.

The electrolyte measuring section 121 is a measuring section that measures the concentration of electrolytes, such as Na ⁺ , K ⁺ , Cl ⁺ ions, etc., in a sample using an ion-selective electrode.

In this embodiment, the analysis module 107 is assumed to be a biochemical test unit that can also measure electrolyte items, and the analysis module 207 is assumed to be an immunological test unit, but the analysis items are not limited to these. The electrolyte measurement section 121 can be removed from the module 107, or a measurement unit for blood coagulation analysis or the like can be appropriately arranged in each module depending on the specification environment.

Further, although examples of a composite automatic analyzer and a multi-module automatic analyzer having measurement units for a plurality of measurement types have been shown, the form of the apparatus is not limited. For example, the configuration may include one analysis module. In this case, the transport module may or may not be provided, and the configuration can be configured according to the user's request.

Furthermore, as in Example 3, which will be described later, three or more analysis modules may be provided. Details of this case will be explained in Example 3.

The control device 300 is a device that controls the entire operation of the automatic analysis device 100, including the analysis modules 107, 207 and the transport module 200, and is a computer or the like equipped with a CPU, memory, and the like. This control device 300 includes a display device 303, an input device 304, a storage device 302, a control section 301, and the like.

The display device 303 displays information such as input screens for various parameters and settings, analysis test data for initial inspection or re-examination, and measurement results, as well as information related to maintenance of the analysis modules 107 and 207 and the transport module 200. This is a display device such as a liquid crystal display. Note that it may be configured with a touch panel display device that also serves as an input device 304, which will be described later.

The input device 304 includes a keyboard and a mouse for inputting various data such as various parameters and settings, analysis request information, and instructions to start analysis.

The storage device 302 is a semiconductor memory such as a flash memory that records measurement results of samples input into the automatic analyzer 100, analysis request information for samples contained in sample containers mounted on each sample rack, etc. It is a recording medium such as a magnetic disk such as an HDD. The storage device 302 also records various parameters and setting values for controlling the operation of each device in the automatic analyzer 100, various computer programs for executing various display processes, etc. to be described later.

Furthermore, the storage device 302 of the present invention stores information on the mask status and its factors, which are set for each sample analysis item in the analysis modules 107 and 207, to maintain reliability of the sample analysis results. There is. These pieces of information will be described in detail later.

The control unit 301 is a part that controls the entire operation of the automatic analyzer 100 including the analysis modules 107 and 207, and corresponds to the above-mentioned CPU or the like.

In this embodiment, the control unit 301 controls the display of a screen on which various information such as information regarding the specimen, information regarding analysis items, and information regarding analysis results is displayed on the display screen of the display device 303. Furthermore, it executes control to display various screens related to the operation of the automatic analyzer 100, such as an operation screen for starting analysis, a screen for instructing the progress of analysis, a screen for instructing execution of maintenance, and information regarding the progress of maintenance.

In particular, in the present embodiment, the control unit 301 displays a mask factor list screen that summarizes the mask status stored in the storage device 302, indicating whether or not masking is performed, and the mask factors corresponding to each mask in the mask status. 500 is displayed on the display device 303 at a predetermined timing.

Furthermore, in this embodiment, the control unit 301 configures the screen of the display device 303 into a global area 500A that is commonly displayed in all states, and a local area 500B whose contents change depending on each state, It is displayed on the display device 303. The masking factor list screen 500 described above is displayed in the local area 500B, as described later.

As a prerequisite for this, the control unit 301 of this embodiment has a masking function that temporarily suspends a specific analysis item. This mask function is determined to be valid or invalid depending on the situation inside the device when maintenance is performed, for example. The masks described in this embodiment include a manual mask, a reagent mask, a calibration mask, a QC mask, an inventory mask, and other masks. The details will be described later using the respective figures.

Note that, in the present invention, the "predetermined timing" for displaying the mask factor list screen 500 is when the mask maintenance button 515 (see FIG. 2, etc.) is pressed, but is not particularly limited to this timing. There isn't.

For example, at the timing when the user of the automatic analyzer 100 is switched, when the automatic analyzer 100 returns from a standby state, or after analysis has been performed for a specified time or a specified number of times in the analysis modules 107 and 207, the automatic analyzer 100 This can be done at least one of the following: upon completion of warm-up, or immediately before the analysis modules 107 and 207 start analysis.

Note that the "prescribed time" and the "prescribed number of times" may be set arbitrarily by the user, or may be predetermined values on the device side. For example, analysis may be performed continuously for 1-2 hours.

The above is the general configuration of the automatic analyzer 100.

The sample analysis process by the automatic analyzer 100 as described above is generally executed in the following order.

The operator gives analysis instructions to the automatic analyzer 100 using the display device 303 and input device 304. The analysis instruction is stored in the storage device 302 and transmitted via the control device 300 to the transport module 200 and the target analysis module among the analysis modules 107 and 207. The target analysis module performs the analysis operation as follows according to the received analysis instruction.

The transport module 200 sends out the sample racks 101 installed in the sample rack supply section 102 onto the transport line 104 one rack at a time, and transports them into the rack rotor 106.

The sample rack 101 transported to the rack rotor 106 is transported to the dispensing line 109 of the analysis module 107 or the dispensing line 209 of the analysis module 207, depending on the analysis item requested by the control device 300.

When the sample racks 101 arrive at the dispensing lines 109 and 209, the sample dispensing mechanisms 108 and 208 perform a dispensing operation on each sample loaded on the sample racks 101.

When the analysis item is a biochemical item, the specimen dispensing mechanism 108 discharges the aspirated specimen into a reaction container located on the reaction disk 118. Thereafter, the reagent sucked from above the reagent disk 119 by the reagent dispensing mechanism 120 is further added to the reaction container and stirred. Thereafter, the absorbance and the like are measured by the measurement unit, and the measurement results are transmitted to the control unit 301 of the control device 300.

The reaction vessel used for analysis is washed with water, alkaline detergent, and acidic detergent dispensed from a washing mechanism (not shown), and used for the next analysis.

When the analysis item is an immunology item, the reagent dispensing mechanism 220 discharges the reagent sucked from the reagent disk 219 into the reaction container on the reaction disk 218, and the sample dispensing mechanism 208 discharges the reagent into the reaction container on the reaction disk 218. Add more sample and stir. Thereafter, after performing processing such as magnetic separation as necessary, the measurement unit performs measurement, and the measurement results are transmitted to the control unit 301 of the control device 300.

If the analysis item is an electrolyte item, the sample dispensing mechanism 108 discharges the aspirated sample into a container within the electrolyte measuring section 121, and the analysis is performed.

The control unit 301 calculates the concentration of a specific component in the sample from the transmitted measurement results through arithmetic processing, and performs processing such as displaying the results on the display device 303 or the like or storing them in the storage device 302.

Next, details of the display screen such as mask factors in the automatic analyzer 100 of this embodiment will be explained using FIG. 2 and subsequent figures.

First, details of the masking factor list screen 500 displayed on the display device 303 of the automatic analyzer of this embodiment will be explained using FIGS. 2 to 4 and the like. FIG. 2 is an example of an item-by-item mask factor screen, FIG. 3 is an example of a screen displaying remaining inventory, and FIG. 4 is a diagram showing an example of a mask details screen transitioned from the screen of FIG. 2.

The mask factor list screen 500 shown in FIG. 2 can be accessed by the user pressing the mask maintenance button 515 displayed in the global area 500A, which is displayed no matter which screen of the device is open.

When recognizing that the mask maintenance button 515 has been pressed, the control unit 301 collects masking factors for registered analysis items from the storage device 302 and displays them on the masking factor list screen 500. This mask factor list screen 500 displays a list of whether or not analysis items can be analyzed by masking.

In the form shown in FIG. 2, the masking factor list screen 500 shows the masking status by item in a table format, and the vertical axis shows an analysis unit item 501, a unit number item 502, and an analysis item 503. .

The horizontal axis shows mask factors, including manual mask status 504, analytical reagent mask status 505, calibration mask status 506, QC mask status 507, stock mask status 508, detergent and diluent mask status 509, and other masks. A status 510 is displayed, and if there is an item in the masking status on the masking factor list screen 500 that causes analysis not to be possible, that masking factor can be displayed.

For example, regarding whether or not it is a masked state, an "x" indicates a masked state (analysis not possible), and "O" indicates an unmasked state (analysis possible).

The manual mask status 504 is manually set by the user, and has a wide range of effects on devices, items, etc. The analytical reagent mask status 505 is manually set by the user, and includes items such as insufficient remaining amount of reagent and expiration date. The calibration mask status 506 is set by the device, such as a lack of calibration results. QC mask status 507 is set by the device, such as insufficient QC results.

The inventory mask status 508 is set by the apparatus according to situations such as insufficient remaining amount of system reagent, expiration date, shortage of consumables, etc., and has a common influence on the analysis modules 107 and 207. The detergent/diluent mask status 509 is set by the device due to insufficient remaining amount of detergent, diluent, etc. or expired expiration date, and affects the analysis modules 107 and 207 in common.

Among these mask statuses, only related items are masked for the analysis reagent mask status 505, calibration mask status 506, and QC mask status 507, but the inventory mask status 508, detergent and diluent mask status 509, and other mask status In 510, all items of the corresponding analysis modules 107 and 207 are masked.

For example, whether or not a certain analysis item is in a masked state can be determined from the item name 503a and mask status 503b. state (analyzable).

In addition, in the mask status 503b, if there are multiple mask factors for a certain analysis item and it is determined that masking is necessary for any one of them, the mask status is set regardless of the status of other items. Display “x”.

In the case shown in FIG. 2, if a certain analysis item is in mask status, manual mask status 504, analytical reagent mask status 505, calibration mask status 506, QC mask status 507, inventory mask status 508, detergent, diluent mask status 509 Either the mask status 510 or the other mask status 510 is in a masked state, and analysis becomes possible by canceling this mask, and the item of the mask status 503b becomes "o".

Other mask status 510 displays any of the following items: remaining amount of reagent, number of remaining tests, and expiration date.

In FIG. 2, the other mask status 510 shows the number of possible analyzes (the number of remaining tests) or the expiration date, and the user can check in advance not only the mask status but also how many analyzes can be performed for that item. You can find out from the list. If the target analysis item uses multiple reagents, the least possible number of analyzes and the shortest expiration date are displayed.

The other mask status 510 may display, in addition to reagents, the remaining amount of consumables used for the item.

Furthermore, in addition to the above-mentioned tabular information, the masking factor list screen 500 shown in FIG. Another selection pulldown 514 and details button 516 are displayed.

In the analysis unit selection pulldown 512, it is possible to select all items, biochemistry items, immunology items, or electrolyte items, and filter and display the items accordingly.

The item/inventory selection pulldown 513 allows selection of whether to display mask factors by item or remaining amount by inventory. When the inventory screen is displayed, an inventory filtering screen 521 that displays the expiration date and remaining amount of each item is displayed.

In addition, the mask status-specific selection pull-down 514 can filter and display all the masked analysis items regardless of their status, only the masked status, or only the unmasked status.

When the check box 511 is selected and the details button 516 at the bottom of FIG. By displaying it like a screen, it is possible to notify the user of more detailed masking factors for the checked items.

The inventory filtering screen 521 shown in FIG. 3 is a screen that is displayed after transitioning from the mask factor list screen 500 when "inventory" is selected from the item/inventory selection pulldown 513 shown in FIG.

In the inventory filtering screen 521, an analysis unit item 501 and a unit number item 502 are displayed on the vertical axis as in FIG. 2. On the horizontal axis, an inventory mask 522, inventory name 522a, mask status 522b, expiration date status 523, and remaining amount status 524 are displayed.

In the inventory filtering screen 521 shown in FIG. 3, similarly to the masking factor list screen 500, "x" indicates a masked state (analysis not possible), and "○" indicates a non-masked state (analysis possible). It is.

Similar to the masking factor list screen 500, this inventory filtering screen 521 can also filter and display information from the analysis unit selection pulldown 512, item/inventory selection pulldown 513, and mask status selection pulldown 514.

The details screen 600 shown in FIG. 4 is a sub-screen that is displayed on the masking factor list screen 500 when the checkbox 511 on the masking factor list screen 500 shown in FIG. 2 is checked and the details button 516 is pressed. It is.

Details are shown in a table format on the details screen 600, including mask status by item 601, item name 601a, mask status 601b, manual mask status 602, manual mask name 602a, mask status 602b, reagent mask status 603, reagent name 603a, mask Status 603b, calibration mask status 604, calibration item name 604a, mask status 604b, QC mask status 605, QC item name 605a, mask status 605b, inventory mask status 606, inventory item name 606a, mask status 606b, detergent, dilution It consists of liquid mask status 607, detergent name, diluted liquid name 607a, and mask status 607b.

This detailed screen 600 shows the masking state displayed on the masking factor list screen 500 in more detail.

In addition, in the manual mask situation 602, the mask situation 602b is a button, and when pressed, a manual mask setting balloon 608 is displayed. By pressing the mask setting button 608a or the mask release button 608b displayed in the manual mask setting balloon 608, the detailed screen 600 is transited to a mask release setting screen for removing the mask.

Guidance is displayed on the mask cancellation setting screen at the transition destination, and by following the guidance, the mask factor can be canceled. Note that the mask release setting screen can be a known screen, and its details will be omitted.

For example, a reagent mask status 603, a calibration mask status 604, a QC mask status 605, an inventory mask status 606, and a detergent/diluent mask status 607 are each buttons.

Click either the reagent mask status 603, which is the reagent registration screen transition button, the inventory mask status 606, which is the inventory registration screen transition button, or the detergent/diluent mask status 607, which is the reagent registration screen transition button. This will transition to the reagent registration screen (mask release setting screen).

By pressing the calibration mask status 604, which is a calibration screen transition button, the screen transitions to the calibration order screen. By pressing the QC mask status 605, which is a QC screen transition button, it is possible to transition to the QC order screen, and the user can intuitively cancel the mask.

By pressing the close button 609, the details screen 600 can be closed and the screen can return to the original mask factor list screen 500.

Describing the details screen 600 in detail, for example, in the case of the %HbA1c item, the mask factor list screen 500 in FIG. 2 shows that a mask is applied because there is no analytical reagent.

However, since Hb and A1c are used as analytical reagents, it is not possible to determine which reagent is missing from the screen of FIG. 2 alone. Therefore, by displaying the details screen 600 in FIG. 4, it can be seen that a mask is applied to the %HbA1c item because there is no Hb reagent. In this case, the user can cancel the reagent mask by registering a new Hb reagent.

Next, the flow of each process related to the mask maintenance function in the automatic analyzer according to this embodiment will be explained with reference to FIG. FIG. 5 is a flowchart of each process related to the mask maintenance function. Each step shown in FIG. 5 is executed by the control unit 301.

In FIG. 5, when it is first recognized that the mask maintenance button 515 has been pressed by the user, the control unit 301 performs maintenance (step S901).

After the maintenance is completed, the control unit 301 calls each masking situation and factor from the storage device 302, and displays the masking factor list screen 500 on the display device 303 (step S902).

Note that in steps S901 and S902, a case is described in which the masking factor list screen 500 is displayed after maintenance is performed in step S901, but when the masking maintenance button 515 is pressed, the masking factor list screen is immediately displayed. 500 may be displayed.

In addition to the timing when the mask maintenance button 515 is pressed as in step S901, the timing when the user of the automatic analyzer 100 is switched, when the automatic analyzer 100 returns from the standby state, etc. After the analysis has been executed for a certain period of time, when the automatic analyzer 100 is warmed up, and immediately before the analysis modules 107 and 207 start analysis, the mask factor list screen 500 is displayed on the display device 303 in the same manner as in step S902. be able to.

Thereafter, the user refers to the masking factor list screen 500 to confirm the presence or absence of masking setting items. If there is a mask item that needs to be canceled in the mask setting items, the user selects the item. The control unit 301 determines whether or not the user selects a masking item (step S903), and if no setting is necessary, no particular selection is made and an area different from the masking factor list screen 500 is selected. If so, the process advances to step S906 and the mask maintenance screen is ended (step S906).

On the other hand, if settings are required, the relevant item is selected, so the control unit 301 advances the process to step S904, opens the details screen 600 as necessary (step S904), and performs mask release settings. (Step S905).

After the cancellation setting, the user confirms again, and if settings are necessary, they are set for all factors. The control unit 301 ends the maintenance when the setting is no longer necessary (step S906).

Next, the effects of this embodiment will be explained.

In the automatic analyzer 100 of the first embodiment of the present invention described above, at a predetermined timing, the mask status stored in the storage device 302, which indicates whether or not the mask is applied, and the mask factors corresponding to each mask in the mask status. By displaying a masking factor list screen 500 summarizing the masking factors on the display device 303, the user can determine at a glance which analysis item is masked and for what reason at a predetermined timing. Therefore, it is possible to efficiently perform a mask setting operation, a mask canceling operation, and an analysis operation, which can lead to improved user efficiency compared to the conventional method.

Furthermore, by displaying a list of each analysis item, the user does not have to check each analysis item or analysis reagent one by one, which leads to an improvement in the user's work efficiency. In addition, it is possible to reduce the risk of having to redo an analysis due to an unintended mask, and to suppress the increase in user effort caused by redoing and the increase in running costs due to preparation, etc. compared to conventional methods. I can do it.

The control unit 301 further includes a mask maintenance button 515 that can be pressed by the user, and the control unit 301 displays the mask factor list screen 500 on the display device 303 when the mask maintenance button 515 is pressed. A mask factor list screen 500 can be displayed. Therefore, convenience for the user can be improved, and analysis efficiency can be further improved.

Furthermore, the predetermined timing is the timing when the user of the automatic analyzer 100 is switched, when the automatic analyzer 100 returns from the standby state, after the analysis has been executed for a prescribed time in the analysis modules 107 and 207, and after which the analysis is executed for a prescribed number of times. After execution, at least one of the following: upon completion of warm-up of the automatic analyzer 100, or immediately before the start of analysis by the analysis modules 107, 207. The user's convenience can be further improved by being able to grasp the mask status and mask factors at a glance, such as when reagents are consumed due to continuous use, or when the expiration date of the calibration curve has not been noticed. can.

Furthermore, if there is an item that cannot be analyzed in the masking status on the masking factor list screen 500, the control unit 301 displays the masking factor, allowing the user to more easily understand the reason why it is masked. Therefore, the processing required to restart the analysis can be quickly executed, and analysis efficiency can be further improved.

Further, regarding reagents, if there is enough reagent to be analyzed even once, the control unit 301 determines that analysis is possible. Therefore, there was a risk that the reagents would run out during the analysis, making it impossible to perform the analysis. Conventionally, in order to avoid such a situation, the user had to check the remaining amount of reagent for each analysis item one by one from the reagent registration screen, which was very time-consuming.

However, the control unit 301 can cause the masking factor list screen 500 to display at least one of the remaining amounts of reagents and consumables used for the item, and the number of remaining tests in addition to the masking status and masking factors. , it is possible to judge at a glance how many more analyzes it will take to run out of reagents, etc. for multiple items, and replenish reagents at an appropriate time before the reagents run out during the entire analysis. Therefore, it becomes possible to more reliably avoid the risk that when a plurality of samples are analyzed, the reagent runs out during the analysis of the first sample and subsequent samples cannot be analyzed.

The control unit 301 also displays the expiration date of the reagents and consumables used for that item on the mask factor list screen 500 in addition to the mask status and mask factors. It is possible to grasp the approximate timing and similarly replenish reagents at appropriate timing.

Furthermore, when a masking factor for an item that cannot be analyzed is selected, the control unit 301 displays the masking factor details screen 600 over the masking factor list screen 500 so that the reason why the analysis item was masked can be easily identified. Since it is possible to make judgments and understand what kind of work is required to perform analysis operations efficiently, it contributes to improvement in analysis efficiency.

Furthermore, when a masking factor for an item that cannot be analyzed is selected, the control unit 301 causes the masking factor list screen 500 to transition to the masking cancellation setting screen, thereby eliminating the need for the user to search for the means necessary to cancel the masking. , analysis can be restarted more easily and quickly, and user convenience can be further improved.

Furthermore, if there are multiple masking factors for a certain analysis item and it is determined that masking is necessary for any one of them, the control unit 301 displays each item as a mask. It is possible to clearly inform the user that analysis cannot be performed, and it is possible to urge the user to take action. Therefore, it is expected that actions for restarting the analysis will be taken more quickly, which can contribute to improving analysis efficiency.

Further, the control unit 301 configures the screen of the display device 303 into a global area 500A that is displayed in common in all states, and a local area 500B whose contents change depending on each state, and controls the mask maintenance button 515. By displaying the mask factor list screen 500 in the global area 500A, the user can display the mask factor list screen 500 at any time of interest, further improving convenience for the user and further improving analysis efficiency. can be achieved.

Note that the screen displayed on the display device 303 does not necessarily need to be composed of the global area 500A and the local area 500B, and may be a screen without the global area 500A.

In such a case, when it is recognized that the mask maintenance button 801 displayed on the order screen 800 as shown in FIG. can be controlled to display the screen. The display area of this screen may also be a sub-screen as shown in FIG. 4, or a separate screen as in Example 2, which will be described later. Note that FIG. 6 is a diagram showing another example of the order screen.

<Example 2>

Unlike the automatic analyzer 100 of Example 1, the automatic analyzer of this embodiment displays a detailed screen 600 as shown in FIG. 4 when the check box 511 is selected and the details button 516 at the bottom of FIG. 2 is clicked. Instead of displaying the mask factor list screen 500 as a child screen, a mask factor details screen 700 as shown in FIG. 7 is displayed by switching from the mask factor list screen 500.

The display contents and functions of the details screen 700 shown in FIG. 7 are the same as those of the details screen 600 shown in FIG. 4, and the details of the masking status of the selected analysis item are displayed. Since the screen is not in a child screen format, pressing the display all items button 701 transitions to the masking factor list screen 500 of FIG. 2, which displays all items.

The other configurations and operations are substantially the same as those of the automatic analyzer and the display device of the automatic analyzer of Example 1 described above, and the details will be omitted.

The automatic analyzer according to the second embodiment of the present invention also provides substantially the same effects as the automatic analyzer according to the first embodiment described above.

In addition, when a masking factor for an item that cannot be analyzed is selected, the details of the masking can be obtained by transitioning from the masking factor list screen 500 to the masking factor details screen 700, although the display format is different from the first embodiment. By selecting and implementing the desired items, the user can learn more about the cause of the mask, and therefore can more efficiently perform mask release operations and analysis operations, leading to improved efficiency.
