Description

[Technical field]

[0001] The embodiments disclosed in this specification and the drawings relate to an automated analysis device and an automated analysis system. [Background technology]

[0002] An automatic analyzer is a device that analyzes components of a test sample corresponding to each measurement item by, for example, optically measuring a reaction solution obtained by mixing a test sample collected from a subject such as blood or a standard sample for each measurement item with a reagent corresponding to each measurement item. In such an automatic analyzer, the reagent is stored in a reagent container in a reagent repository of the automatic analyzer.

[0003] Conventionally, in an automatic analyzer, as one of the methods for managing the amount of reagent stored in a reagent repository, a reagent remaining processing warning can be set for each reagent to warn that a specified amount of reagent remains. Then, a user refers to the reagent remaining processing warning output from the device to determine whether or not to continue the measurement process of the measurement item.

[0004] However, it is rare to measure one measurement item for one test and link the measurement results to a diagnosis. Instead, users measure multiple measurement items as one set for one test and comprehensively judge the measurement results of each of the multiple measurement items to link them to a diagnosis. For this reason, the user's decision on whether to continue the measurement process when a reagent remaining processing warning is issued must be made in consideration of the processing status of the set including multiple measurement items. Therefore, if a group of multiple measurement items that need to be measured simultaneously clinically can be managed as one set, the user's burden in judging whether to continue the measurement process can be reduced, and the sample (specimen) can be processed efficiently.

[0009] Hereinafter, an embodiment of an automatic analyzer and an automatic analysis system will be described with reference to the drawings. In the following description, components having substantially the same functions and configurations are denoted by the same reference numerals, and duplicated descriptions will be given only when necessary.

[0010] [First embodiment] FIG. 1 is a block diagram showing an example of the functional configuration of an automatic analyzer according to the first embodiment. The automatic analyzer 10 according to this embodiment is an apparatus that analyzes a mixture of a sample and a reagent using the sample and a reagent corresponding to a measurement item of the sample. In other words, the automatic analyzer 10 is an apparatus that measures components in a sample by measuring a mixture obtained by adding a reagent to a sample to be measured. As shown in FIG. 1, the automatic analyzer 10 according to this embodiment is configured to include, for example, an analysis mechanism 20, an analysis circuit 30, a drive mechanism 40, an input interface 50, an output interface 60, a communication interface 70, a memory circuit 80, and a control circuit 90.

[0011] The analysis mechanism 20 adds a reagent corresponding to the measurement item of a sample, such as a standard sample or a test sample, to the sample. The analysis mechanism 20 measures the mixed liquid obtained by adding the reagent to the sample, and generates, for example, standard data and test data. In this embodiment, the standard data represents the measurement result of absorbance for a standard sample containing a known concentration of the analyte. The test data represents the measurement result of absorbance for the test sample. In the following, when there is no distinction between the standard sample and the test sample, they may be simply referred to as "sample".

[0012] The analysis circuit 30 is a processor that generates calibration data, analysis data, etc. by analyzing the standard data and test data generated by the analysis mechanism 20. The analysis circuit 30 reads an analysis program from the storage circuit 80, and generates calibration data, analysis data, etc. according to the read analysis program. For example, the analysis circuit 30 generates standard data and calibration data that indicates a relationship with a standard value previously set for a standard sample based on the standard data. The analysis circuit 30 also generates analysis data expressed as a concentration value and an enzyme activity value based on the test data and calibration data of a test item corresponding to the test data. The analysis circuit 30 outputs the generated calibration data, analysis data, etc. to the control circuit 90.

[0013] The drive mechanism 40 drives the analysis mechanism 20 under the control of the control circuit 90. For example, the drive mechanism 40 is realized by a gear, a stepping motor, a belt conveyor, a lead screw, or the like.

[0014] The input interface 50 accepts, for example, settings of analysis parameters for each measurement item related to the sample requested to be measured. The input interface 50 is realized by, for example, a mouse, a keyboard, and a touch pad where instructions are input by touching the operation surface. The input interface 50 is connected to the control circuit 90, converts operation instructions input by a user into electrical signals, and outputs the electrical signals to the control circuit 90. In this embodiment, the input interface 50 is not limited to only those having physical operation parts such as a mouse and a keyboard. For example, an electrical signal processing circuit that receives an electrical signal corresponding to an operation instruction input from an external input device provided separately from the automatic analyzer 10 and outputs the electrical signal to the control circuit 90 is also included as an example of the input interface 50.

[0015] The output interface 60 is connected to the control circuit 90 and outputs a signal supplied from the control circuit 90. The output interface 60 is realized by, for example, a display circuit, a printed circuit, an audio device, and the like. The display circuit includes, for example, a CRT (Cathode Ray Tube) display, a liquid crystal display, an organic EL (Electro Luminescence) display, an LED display, and a plasma display. This display circuit corresponds to the display unit in this embodiment. The display circuit also includes a processing circuit that converts data representing a display object into a video signal and outputs the video signal to the outside. The printed circuit includes, for example, a printer, and the like. The printed circuit also includes an output circuit that outputs data representing a print object to the outside. The audio device includes, for example, a speaker, and the like. The audio device also includes an output circuit that outputs an audio signal to the outside.

[0016] The communication interface 70 is connected to, for example, an intra-hospital network NW, and connects the automatic analyzer 10 to the intra-hospital network NW. The communication interface 70 performs data communication with a Hospital Information System (HIS) via the intra-hospital network NW. The communication interface 70 may also perform data communication with an HIS via a Laboratory Information System (LIS) connected to the intra-hospital network NW.

[0017] The memory circuit 80 is composed of a processor-readable recording medium such as a magnetic or optical recording medium, or a semiconductor memory. The memory circuit 80 stores an analysis program executed by the analysis circuit 30 and a control program executed by the control circuit 90. The memory circuit 80 also stores analysis data generated by the analysis circuit 30 for each measurement item. As will be described in detail later, the memory circuit 80 also stores reagent information, item information, and item set information. The memory circuit 80 corresponds to the memory unit according to this embodiment. The memory circuit 80 does not necessarily have to be realized by a single storage device. For example, the memory circuit 80 can be realized by multiple storage devices.

[0018] The control circuit 90 is a processor that functions as the core of the automatic analyzer 10. The control circuit 90 executes an operation program stored in the memory circuit 80 to realize a function corresponding to the operation program. The control circuit 90 may include a memory area for storing at least a portion of the data stored in the memory circuit 80.

[0019] Fig. 2 is a schematic diagram showing the configuration of the analysis mechanism 20 according to the first embodiment.

Specifically, during an analysis operation of a reaction solution of a sample and a reagent, the reaction disk 201 is alternately rotated and stopped at predetermined time intervals by the drive mechanism 40. The reaction vessels 2011 are formed of, for example, glass, polypropylene (PP), or acrylic.

[0021] The thermostatic unit 202 stores a heat medium set to a predetermined temperature. The thermostatic unit 202 heats and keeps the temperature of the reaction liquid contained in the reaction vessel 2011 to a predetermined temperature by immersing the reaction vessel 2011 in the stored heat medium.

Also, a reader (not shown) is provided in the first reagent storage 204 to read reagent information from reagent labels attached to the reagent containers. The read reagent information is stored in the memory circuit 80.

[0026] A first reagent aspirating position is set at a predetermined position on the first reagent storage 204. The first reagent aspirating position is provided at a position where the rotation path of the first reagent dispensing probe 209 and the movement path of the openings of the reagent containers and standard sample containers arranged in a circular shape on the reagent rack 2041 intersect, for example.

[0027] The second reagent storage 205 keeps a plurality of reagent containers refrigerated, each containing a second reagent paired with a first reagent of a two-reagent system. The second reagent is a solution containing an insoluble carrier, for example, carrier particles, on which an antigen or antibody that binds or dissociates by a specific antigen-antibody reaction with a specific antigen or antibody contained in a sample is immobilized. The substance that binds or dissociates by a specific reaction may be an enzyme, a substrate, an aptamer, or a receptor. A reagent rack 2051 is provided in the second reagent storage 205 so as to be freely rotatable. In the following description, when the first reagent storage 204 and the second reagent storage 205 are expressed without distinction, they may be simply referred to as "reagent storage".

[0028] The reagent rack 2051 holds a plurality of reagent containers arranged in a circular ring shape. Note that a standard sample container that contains a standard sample may be kept cool in the second reagent storage 205. The reagent rack 2051 is rotated by the drive mechanism 40. Also, a reader (not shown) that reads reagent information from a reagent label affixed to the reagent container is provided in the second reagent storage 205. The read reagent information is stored in the memory circuit 80.

The second reagent aspirating position is provided at a position where the rotation path of the second reagent dispensing probe 211 and the movement path of the openings of the reagent containers arranged in a circular shape on the reagent rack 2051 intersect, for example.

[0030] The sample dispensing arm 206 is provided between the reaction disk 201 and the sample disk 203. The sample dispensing arm 206 is provided so as to be movable up and down in the vertical direction and rotatable in the horizontal direction by a driving mechanism 40.

[0032] The sample dispensing probe 207 is driven by the drive mechanism 40 and moves up and down at the dispensing position or the sample discharge position. The sample dispensing probe 207 also aspirates a sample from a sample container held on the sample disk 203 at the dispensing position under the control of the control circuit 90. The sample dispensing probe 207 also discharges the aspirated sample into a reaction container 2011 located directly below the sample discharge position under the control of the control circuit 90.

[0033] The first reagent dispensing arm 208 is provided near the outer periphery of the first reagent storage 204. The first reagent dispensing arm 208 is provided so as to be movable up and down in the vertical direction and rotatable in the horizontal direction by the drive mechanism 40. The first reagent dispensing arm 208 holds a first reagent dispensing probe 209 at one end.

[0034] The first reagent dispensing probe 209 rotates along an arc-shaped rotation orbit in association with the rotation of the first reagent dispensing arm 208. The above-mentioned first reagent aspirating position is provided on this rotation orbit. In addition, a first reagent dispensing position for discharging the first reagent or standard sample aspirated by the first reagent dispensing probe 209 into the reaction vessel 2011 is set on the rotation orbit of the first reagent dispensing probe 209. The first reagent dispensing position is provided at a position where the rotation orbit of the first reagent dispensing probe 209 and the movement orbit of the reaction vessel 2011 held on the reaction disk 201 intersect.

[0035] The first reagent dispensing probe 209 is driven by the drive mechanism 40 and moves up and down at a first reagent aspirating position or a first reagent dispensing position on the rotation orbit. The first reagent dispensing probe 209 also aspirates the first reagent or standard sample from a reagent container located directly below the first reagent aspirating position under the control of the control circuit 90. The first reagent dispensing probe 209 also discharges the aspirated first reagent or standard sample into a reaction container 2011 located directly below the first reagent dispensing position under the control of the control circuit 90.

[0036] The second reagent dispensing arm 210 is provided near the outer periphery of the first reagent storage 204. The second reagent dispensing arm 210 is provided so as to be movable up and down in the vertical direction and rotatable in the horizontal direction by the drive mechanism 40. The second reagent dispensing arm 210 holds a second reagent dispensing probe 211 at one end.

[0037] The second reagent dispensing probe 211 rotates along an arc-shaped rotation orbit in association with the rotation of the second reagent dispensing arm 210. The above-mentioned second reagent aspirating position is provided on this rotation orbit. In addition, a second reagent dispensing position for discharging the second reagent aspirated by the second reagent dispensing probe 211 into the reaction vessel 2011 is set on the rotation orbit of the second reagent dispensing probe 211. The second reagent dispensing position is provided at a position where the rotation orbit of the second reagent dispensing probe 211 and the movement orbit of the reaction vessel 2011 held on the reaction disk 201 intersect.

[0038] The second reagent dispensing probe 211 is driven by the drive mechanism 40 and moves up and down at a second reagent aspirating position or a second reagent dispensing position on the rotation orbit. The second reagent dispensing probe 211 also aspirates the second reagent from a reagent container located directly below the second reagent aspirating position under the control of the control circuit 90. The second reagent dispensing probe 211 also discharges the aspirated second reagent into a reaction container 2011 located directly below the second reagent dispensing position under the control of the control circuit 90.

[0039] The first stirring unit 212 is provided near the outer periphery of the reaction disk 201. The first stirring unit 212 has a first stirring arm 2121 and a first stirring bar provided at the tip of the first stirring arm 2121. The first stirring unit 212 stirs the reaction liquid of the standard sample and the first reagent contained in the reaction vessel 2011 located at the first stirring position on the reaction disk 201 with the first stirring bar. The first stirring unit 212 also stirs the reaction liquid of the test sample and the first reagent contained in the reaction vessel 2011 located at the first stirring position on the reaction disk 201 with the first stirring bar.

[0040] The second stirring unit 213 is provided near the outer periphery of the reaction disk 201. The second stirring unit 213 has a second stirring arm 2131 and also has a second stirring bar provided at the tip of the second stirring arm 2131. The second stirring unit 213 uses the second stirring bar to stir the reaction liquid of the standard sample, the first reagent, and the second reagent contained in the reaction vessel 2011 located at the second stirring position on the reaction disk 201.

[0041] The photometry unit 214 optically measures the reaction liquid of the sample, the first reagent, and the second reagent dispensed into the reaction vessel 2011. The photometry unit 214 has a light source 2141 and a photodetector 2142. The photometry unit 214 irradiates light from the light source in accordance with the control of the control circuit 90. The irradiated light is incident on a first side wall of the reaction vessel 2011 and is emitted from a second side wall opposite the first side wall. The photometry unit 214 detects the light emitted from the reaction vessel 2011 by the photodetector 2142.

[0042] Specifically, for example, the photodetector 2142 is disposed at a position on the optical axis of the light irradiated from the light source 2141 to the reaction vessel 2011. The photodetector 2142 detects light transmitted through the reaction solution of the standard sample, the first reagent, and the second reagent in the reaction vessel 2011. The automatic analyzer 10 acquires photometric data represented by the intensity of the light detected by the photodetector 2142.

The photodetector 2142 also detects light transmitted through the reaction solution of the test sample, the first reagent, and the second reagent in the reaction vessel 2011. The automatic analyzer 10 acquires photometric data represented by the intensity of the light detected by the photodetector 2142. The automatic analyzer 10 then generates test data represented by absorbance based on measurement data acquired at a predetermined timing from the photometric data. The photometry unit 214 outputs the generated standard data and test data to the analysis circuit 30 .

[0043] The cleaning unit 215 cleans the inside of the reaction container 2011 after the measurement of the reaction liquid by the photometry unit 214 has been completed.

[0044] 1 is configured to include an item information storage circuit 81, a reagent information storage circuit 82, and an item set information storage circuit 83. The item information storage circuit 81, the reagent information storage circuit 82, and the item set information storage circuit 83 may be realized by a single storage device or may be realized by multiple storage devices.

[0045] The item information storage circuit 81 stores item information. Specifically, the item information storage circuit 81 stores item information related to information required for measuring measurement items that can be measured by the analysis mechanism 20. For example, this item information stores information related to the measurement item, the amount of sample required for measuring the measurement item, information related to the reagent added when measuring the measurement item, the number of remaining processing warnings, and priority information related to the priority. Note that the item information may include information other than the measurement item, the amount of sample required for measuring the measurement item, information related to the reagent added when measuring the measurement item, the number of remaining processing warnings, and priority information related to the priority. This item information is also referred to as an assay parameter. Furthermore, hereinafter, the number of remaining processing warnings in the item information is also referred to as the second number of remaining processing warnings as appropriate.

[0046] Examples of measurement items include "TP (Total Protein)", "CRE (Creatinine)", "ALP (Alkaline Phosphatase)", "γ-GT", "GOT (AST)", "T-BIL (Total Bilrubin)", etc. Information on a reagent added when measuring a measurement item includes, for example, the name of the reagent added when measuring the measurement item, the amount of reagent added when measuring the measurement item, etc.

[0047] The remaining processing warning number in the item information is the second remaining processing number when the warning function described later outputs a warning to the user. This second remaining processing number indicates the remaining processing number of the measurement item in the item information, and is indicated, for example, by the remaining amount of reagent corresponding to the measurement item, or the remaining test number obtained by dividing the remaining amount of reagent corresponding to the measurement item by the reagent amount in the item information. Therefore, the remaining amount of reagent corresponding to the measurement item when the warning is output, the remaining test number of the measurement item when the warning is output, etc. are set as the second remaining processing number when the warning is output in the remaining processing warning number in the item information. This remaining processing warning number in the item information corresponds to the second threshold in this embodiment. Moreover, the priority information is information regarding the priority of the measurement processing of this measurement item and the item set described later.

[0048] FIG. 3 is a diagram showing an example of item information displayed on the display circuit of the automatic analyzer 10 according to this embodiment. As shown in FIG. 3, the display circuit 61, which is an example of the output interface 60, displays an item information setting screen S1, which is a screen for setting item information. In the example shown in FIG. 3, the item information setting screen S1 displays, as item information, a measurement item, a reagent name in the information on the reagent, and a reagent amount, a remaining processing warning indicating the number of remaining processing warnings in the item information, and a priority order, which is an example of priority information. More specifically, in the example shown in FIG. 3, the item information setting screen S1 displays, as item information, a measurement item "A", a first reagent "ReagentA-1" and its reagent amount "150", a second reagent "ReagentA-2" and its reagent amount "50", a remaining processing warning "XX times", and a priority order "3". In the item information setting screen S1, the user can arbitrarily set remaining processing warnings, priority orders, etc. for each measurement item via the input interface 50.

[0049] The reagent information storage circuit 82 stores reagent information. Specifically, the reagent information storage circuit 82 stores reagent information, which is information about the reagent stored in the reagent repository. The reagent information is information about the reagent, and includes, for example, the reagent name, bottle type, reagent bottle size, capacity, the position of the reagent container in the reagent repository in which the reagent is accommodated, the status of the reagent, reagent remaining amount information about the remaining amount of the reagent, expiration date, and warning information about the remaining amount and expiration date of the reagent. The warning information is information for outputting a warning to the user about the reagent, and includes, for example, information about the remaining amount of the reagent when a warning is output to the user, and information about the expiration date of the reagent when a warning is output to the user. This warning information is information that can be set by the user for each reagent.

[0050] FIG. 4 is a diagram showing an example of a reagent management screen displayed on the display circuit 61 of the automatic analyzer 10 according to this embodiment. As shown in FIG. 4, the reagent management screen S2 displays reagent storage information related to the reagent storage in which the reagent is stored, and a reagent list showing a list of the reagents stored in the reagent storage. More specifically, in the example shown in FIG. 4, the reagent management screen S2 displays a diagram showing a schematic diagram of the reagent storage as the reagent storage information. For example, the name of the reagent or the like is superimposed on the diagram showing the schematic diagram of the reagent storage. In addition, in the example shown in FIG. 4, the reagent management screen S2 displays a position, an item, a status, and a remaining amount as a reagent list. In the reagent list, the position is information about the position of the reagent container in which the reagent is stored in the reagent storage. Also, the item is information about the measurement item in the item information corresponding to the reagent. Also, the status is information about the state of the reagent, such as "calibration not completed", "usable", "invalid", "expired", etc. Also, the remaining amount is information about the remaining amount of the reagent in the reagent storage.

[0051] 4, the remaining amount of reagent is displayed in the reagent list, but instead of or together with the remaining amount of reagent, the number of remaining tests obtained by dividing the remaining amount of reagent corresponding to the measurement item by the reagent amount in the item information may be displayed. Also, the reagent management screen S2 displays the position, item, status, and remaining amount as the reagent list, but the information displayed as the reagent list is not limited to this. In other words, the content displayed as the reagent list on the reagent management screen S2 is arbitrary, and information other than the position, item, status, and remaining amount may be displayed on the reagent management screen S2.

[0052] The item set information storage circuit 83 stores the item set information. The item set information is information about an item set in which multiple measurement items are assigned to a test. A test refers to various tests performed on a sample, and includes, for example, basic tests and emergency tests set by a user in a biochemical test. This item set information includes, for example, an item set name, measurement items, the number of remaining process warnings, priority information, and the like. The item set name is information about the name of the item set. Note that the item set information may include information other than the item set name, measurement items, the number of remaining process warnings, and priority information. In the following, the number of remaining process warnings in the item set information is also referred to as the first number of remaining process warnings, as appropriate.

[0053] The measurement item in the item set information is information such as the name of the measurement item assigned to this item set. Based on the measurement item in this item set information, the item information in the measurement item is associated with the item set information. The remaining processing warning number in the item set information is the first remaining processing number when the warning function described later outputs a warning to the user. This first remaining processing number indicates the remaining processing number of the item set in the item set information, and is indicated by, for example, the remaining amount of reagent corresponding to the measurement item assigned to the item set, or the remaining test number obtained by dividing the remaining amount of reagent corresponding to the measurement item assigned to the item set by the reagent amount in the item information including the measurement item assigned to the item set. For this reason, the remaining processing warning number in the item set information is set to the remaining amount of reagent corresponding to the measurement item assigned to the item set when the warning is output, or the remaining test number of the item set when the warning is output, as the first remaining processing number when the warning is output. The remaining processing warning number in this item set information corresponds to the first threshold in this embodiment. Furthermore, the priority information is information regarding the priority of the measurement processing of this measurement item and item set.

[0054] FIG. 5 is a diagram showing an example of item set information displayed on the display circuit 61 of the automatic analyzer 10 according to this embodiment. As shown in FIG. 5, the display circuit 61 displays an item set information setting screen S3, which is a screen for setting item set information. In the example shown in FIG. 5, the item set information setting screen S3 displays, as item set information, the item set name, the measurement item, the remaining processing warning indicating the number of remaining processing warnings in the item set information, and the priority order, which is an example of priority information. More specifically, in the example shown in FIG. 5, the item set information setting screen S3 displays the item set name "set X", the measurement items "A, B, C", the remaining processing warning "XX times", and the priority order "1". Comparing FIG. 5 with the example shown in FIG. 3 described above, it is shown that the priority order of set X is higher than that of the measurement item "A" shown in FIG. 3. In the item set information setting screen S3, the user can set the remaining processing warning, the priority order, and the like for each item set via the input interface 50.

[0055] 1 executes a control program to realize a system control function 91, an acquisition function 92, a calculation function 93, and a warning function 94. In the present embodiment, a case in which the system control function 91, the acquisition function 92, the calculation function 93, and the warning function 94 are realized by a single processor will be described, but the present invention is not limited to this. For example, the control circuit may be configured by combining a plurality of independent processors, and the system control function 91, the acquisition function 92, the calculation function 93, and the warning function 94 may be realized by each processor executing a control program.

[0056] The system control function 91 is a function that comprehensively controls each part of the automatic analyzer 10 based on input information input from the input interface 50. For example, the system control function 91 controls the drive mechanism 40 and the analysis mechanism 20 in the control circuit 90, and also controls the analysis circuit 30 so as to perform an analysis according to the measurement item. The system control function 91 corresponds to the system control unit in this embodiment.

[0057] The acquisition function 92 acquires reagent information, item information, and item set information from the memory circuitry 80 etc. The acquisition function 92 corresponds to the acquisition unit in this embodiment.

[0058] The calculation function 93 calculates a first remaining processing number indicating the remaining processing number of the item set based on the reagent remaining amount information and the item set information. Specifically, the calculation function 93 calculates a second remaining processing number indicating the remaining processing number of the measurement item for each of the multiple measurement items in the item set information based on the reagent remaining amount information and item information of the measurement items included in the item set information, and calculates the smallest second remaining processing number of the multiple calculated second remaining processing numbers as the first remaining processing number. The calculation function 93 corresponds to the calculation unit in this embodiment.

[0059] The method of calculating the first remaining number of processes is not limited to the case of calculating the smallest second remaining number of processes among the calculated second remaining numbers as the first remaining number of processes. That is, the method of calculating the first remaining number of processes is arbitrary, and for example, the calculation function 93 may calculate the rate of change of the second remaining number of processes within a predetermined period and the second remaining number for each of the multiple measurement items in the item set information, and calculate the second remaining number with the largest rate of change of the second remaining number of processes within the predetermined period as the first remaining number of processes.

[0060] The warning function 94 outputs a warning when the first remaining processing number calculated by the calculation function 93 falls below the remaining processing warning number in the item set information. The warning function 94 also outputs a warning when the remaining amount of reagent or the expiration date of the reagent falls below the threshold of the warning information in the reagent information. The warning function 94 also outputs a warning when the second remaining processing number falls below the remaining processing warning number in the item information. The warning function 94 corresponds to the warning unit in this embodiment.

[0061] Fig. 6 is a flow chart illustrating the contents of the item set warning process executed by the automated analyzer 10 shown in Fig. 2. In this item set warning process, a first remaining number of processes is calculated and a warning is output to the user. For example, the item set warning process is a process that is executed when a measurement instruction for an item set is input.

[0062] 6, first, the system control function 91 of the control circuit 90 determines whether or not a measurement instruction for the item set has been input (step S11). If a measurement instruction for the item set has not been input (step S11: No), the system control function 91 waits and repeats the process of step S11 until a measurement instruction for the item set is input.

[0063] On the other hand, if a measurement instruction for the item set is input in step S11 (step S11: Yes), the acquisition function 92 of the control circuit 90 acquires item set information (step S13). Specifically, the acquisition function 92 acquires, from the storage circuitry 80, the item set information for the item set for which a measurement instruction was input in step S11.

[0064] 6, the acquisition function 92 of the control circuit 90 acquires item information (step S15). Specifically, the acquisition function 92 acquires item information corresponding to the measurement items included in the item set information acquired in step S13 from the storage circuit 80. If the item set information includes item information corresponding to the measurement items included in the item set information, the item set information is acquired in step S13, and step S15 is omitted because the item information has already been acquired.

[0065] 6, the acquisition function 92 of the control circuit 90 acquires reagent information (step S17). Specifically, the acquisition function 92 acquires reagent information corresponding to the information on the reagent included in the item information acquired in step S15 from the storage circuit 80. Note that in step S17, the acquisition function 92 may acquire only the reagent remaining amount information from among the reagent information.

[0066] Next, as shown in FIG. 6, the calculation function 93 of the control circuit 90 calculates the first remaining number of processes (step S19). Specifically, the calculation function 93 calculates the first remaining number of processes of the item set for which the measurement instruction was input in step S11 based on the reagent remaining amount information in the reagent information acquired in step S15 and the item set information acquired in step S13. More specifically, when calculating the remaining amount of reagent as the first remaining number of processes, the calculation function 93 calculates the smallest remaining amount of reagent among the remaining amounts of reagent corresponding to the measurement items assigned to the item set as the first remaining number of processes. Also, when calculating the remaining number of tests as the first remaining number of processes, the calculation function 93 calculates the remaining number of tests of each of the multiple measurement items by dividing the remaining amount of reagent corresponding to each of the multiple measurement items assigned to the item set by the amount of reagent required for each of the multiple measurement items assigned to the item set for each of the multiple measurement items assigned to the item set. Then, the calculation function 93 calculates the smallest remaining number of tests among the remaining numbers of tests of each of the multiple measurement items as the first remaining number of processes.

[0067] 6, the warning function 94 of the control circuit 90 determines whether the first remaining number of processes is below the first remaining warning number (step S21). Specifically, the warning function 94 determines whether the first remaining number of processes is below the first remaining warning number by comparing the first remaining number of processes calculated in step S19 with the first remaining warning number in the item set information.

[0068] Then, in step S21, if the first remaining number of processes falls below the first remaining warning number (step S21: Yes), the warning function 94 outputs a warning (step S23). Specifically, the warning function 94 outputs a warning that the first remaining number of processes has fallen below the first remaining warning number via the output interface 60. The warning function 94 may be configured to output the first remaining number of processes of the item set together with the warning that the first remaining number of processes has fallen below the first remaining warning number. The warning function 94 may also be configured to output the second remaining numbers of each of the multiple measurement items assigned to the item set together with the warning that the first remaining number of processes has fallen below the first remaining warning number.

[0069] Then, when the first remaining process count is not below the first remaining process warning count (step S21: No), or when the process of step S23 has been executed, the itemset warning process according to this embodiment ends.

[0070] As described above, the automated analyzer 10 of this embodiment stores item set information for an item set to which multiple measurement items are assigned, calculates a first remaining processing number indicating the remaining number of processes in the item set, and outputs a warning if the first remaining processing number falls below the first remaining processing warning number for the item set.Therefore, it is possible to manage the remaining processing number for each set, with multiple measurement items as one set, and sample processing can be performed efficiently while reducing the burden on the user.

[0071] In step S11 of the item set warning process according to the present embodiment described above, the item set warning process is executed when an instruction to measure an item set is input, but the timing at which the item set warning process starts is not limited to this. That is, the timing at which the item set warning process starts can be arbitrary, and for example, the item set warning process may be started at predetermined time intervals, may be started when a sample is introduced into the automated analyzer 10, or may be started when measurement of one item set or measurement item is completed.

[0072] In the first embodiment described above, the itemset information and the item information do not necessarily need to include priority information.

[0073] Second Embodiment In the automated analyzer 10 according to the first embodiment described above, it is also possible to control the processing of measurement items and / or item sets based on priority information set in the item information and item set information. Hereinafter, a second embodiment will be described taking as an example a case where this modified example is applied to the first embodiment described above.

[0074] Fig. 7 is a block diagram showing an example of the functional configuration of an automatic analyzer 10 according to the second embodiment, and corresponds to Fig. 1 according to the first embodiment. As shown in Fig. 7, in the automatic analyzer 10 according to this embodiment, a control circuit 90 is additionally provided with a first process control function 95.

[0075] The first processing control function 95, like the other functions, is realized by the control circuit 90 reading and executing a program stored in the memory circuit 80. This first processing control function 95 controls the processing of measurement items and item sets based on priority information set in the item information and item set information. This first processing control function 95 corresponds to the first processing control unit in this embodiment.

[0076] Fig. 8 is a flow chart illustrating the contents of the measurement process executed by the automated analyzer 10 shown in Fig. 7. In this measurement process, the measurement of the item set for which a measurement instruction has been issued is executed, or the measurement of the measurement item for which a measurement instruction has been issued is executed, based on priority information set in the item set information and / or item information. For example, the measurement process is executed when a measurement instruction for an item set or a measurement instruction for a measurement item is input. In addition, this measurement process is executed for each measurement instruction for an item set or measurement item.

[0077] First, the system control function 91 of the control circuit 90 determines whether or not an instruction to measure the item set has been input (step S31). If an instruction to measure the item set has been input in step S31 (step S31: Yes), the acquisition function 92 of the control circuit 90 acquires item set information (step S13). The process from step S13 to step S17 is similar to the item set warning process in the first embodiment described above, and therefore will not be described here.

[0078] After this step S17, the first process control function 95 of the control circuit 90 judges whether or not there is a measurement item whose second remaining process number is less than the second remaining process warning number (step S33). Specifically, the first process control function 95 judges whether or not there is a measurement item whose second remaining process number is less than the second remaining process warning number based on the item set information acquired in step S13, the item information acquired in step S15, and the reagent information acquired in step S17. More specifically, when the remaining test warning number is set as the second remaining process warning number, the first process control function 95 calculates the remaining test number as the second remaining process number for each of the multiple measurement items assigned to the item set based on the reagent amount in the item information and the remaining amount of reagent in the reagent remaining amount information in the reagent information, and judges whether or not the remaining test number of each of the multiple measurement items is less than the remaining test warning number, which is the second remaining process warning number of each of the multiple measurement items, thereby judging whether or not there is a measurement item whose second remaining process number is less than the second remaining process warning number.

[0079] If there is a measurement item whose second remaining process count is less than the second remaining process warning count (step S33: Yes), the first process control function 95 of the control circuit 90 determines whether the measurement item whose second remaining process count is less than the second remaining process warning count is assigned to another itemset (step S35). Specifically, the first process control function 95 determines whether the measurement item whose second remaining process count is less than the second remaining process warning count is assigned to an itemset other than the itemset in the itemset information acquired in step S13.

[0080] Then, in step S35, if the measurement item whose second remaining process count is less than the second remaining process warning count is assigned to another itemset (step S35: Yes), the first process control function 95 of the control circuit 90 acquires itemset information of the itemset to which the measurement item whose second remaining process count is less than the second remaining process warning count is assigned (step S37). Specifically, the first process control function 95 acquires itemset information of itemsets to which the measurement item whose second remaining process count is less than the second remaining process warning count is assigned, other than the itemsets in the itemset information acquired in step S13, from the itemset information storage circuit 83 of the storage circuit 80.

[0081] On the other hand, in step S35, if the measurement item whose second remaining process count is less than the second remaining process warning count is not assigned to another item set (step S35: No), or after step S37, the first process control function 95 of the control circuit 90 determines whether there is an item set and / or measurement item with a higher priority than the priority of the item set for which a measurement instruction has been issued (step S39). Specifically, the first process control function 95 determines whether there is an item set and / or measurement item with a higher priority than the priority of the item set for which a measurement instruction has been issued, by comparing the priority information in the item set information acquired in step S13 with the priority information in the item information acquired in step S15 and / or the priority information in the item set information acquired in step S37.

[0082] If there is an item set and / or measurement item with a higher priority than the item set for which a measurement instruction has been given (step S39: Yes), the first process control function 95 of the control circuit 90 determines whether there is a measurement instruction for an item set and / or measurement item with a higher priority than the item set for which a measurement instruction has been given (step S41). Specifically, the first process control function 95 determines whether a measurement instruction has been input for an item set and / or measurement item with a higher priority than the item set for which a measurement instruction was input in step S11.

[0083] If there is a measurement instruction for an item set and / or measurement item with a higher priority than the priority of the item set for which the measurement instruction has been given (step S41: Yes), the process returns to step S33 and waits while repeating the processes from step S33 to step S41. That is, the first process control function 95 waits for measurement of the item set for which the measurement instruction has been input until the remaining amount of reagent exceeds the second remaining process warning number due to the reagent being replenished in step S33, or until the priority of the item set for which the measurement instruction has been given is changed in step S39 and the priority is increased, or until measurement of an item set and / or measurement item with a higher priority than the priority of the item set for which the measurement instruction has been given in step S41 is completed.

[0084] On the other hand, if there is no measurement item whose second remaining processing count is less than the second remaining processing warning count in step S33 (step S33: No), if there is no item set and / or measurement item with a higher priority than the item set for which a measurement instruction was given in step S39 (step S39: No), or if there is no measurement instruction for an item set and / or measurement item with a higher priority than the item set for which a measurement instruction was given in step S41 (step S41: No), the first process control function 95 of the control circuit 90 causes the measurement of the item set to be performed (step S43). Specifically, the first process control function 95 causes the system control function 91 to start control of the analysis mechanism 20, and causes the measurement of the item set for which a measurement instruction was input to be performed.

[0085] On the other hand, if a measurement instruction for the item set has not been input in step S31 (step S31: No), the system control function 91 of the control circuit 90 determines whether a measurement instruction for the measurement item has been input (step S45). If a measurement instruction for the measurement item has not been input in step S45 (step S45: No), the system control function 91 waits and repeats the processes of steps S31 and S45 until a measurement instruction for the item set or measurement item is input.

[0086] On the other hand, if a measurement instruction for the measurement item has been input in step S45 (step S45: Yes), the acquisition function 92 of the control circuit 90 acquires item information (step S47). The acquisition function 92 acquires item information for the measurement item for which a measurement instruction was input in step S31 from the item information storage circuit 81 of the storage circuit 80.

[0087] 8, the acquisition function 92 of the control circuit 90 acquires reagent information (step S49). Specifically, the acquisition function 92 acquires reagent information corresponding to the information on the reagent included in the item information acquired in step S47 from the reagent information storage circuit 82 of the storage circuit 80. Note that in step S49, the acquisition function 92 may acquire only the reagent remaining amount information from the reagent information.

[0088] Next, as shown in Fig. 8, the first process control function 95 of the control circuit 90 judges whether the second remaining process number is below the second remaining process warning number (step S51). Specifically, the first process control function 95 judges whether the second remaining process number is below the second remaining process warning number based on the item information acquired in step S47 and the reagent information acquired in step S49. More specifically, when the remaining test warning number is set as the second remaining process warning number, the first process control function 95 calculates the remaining test number as the second remaining process number based on the amount of reagent in the item information and the remaining amount of reagent in the reagent information, and judges whether the remaining test number is below the remaining test warning number, which is the second remaining process warning number, thereby judging whether the second remaining process number is below the second remaining process warning number.

[0089] Then, in step S51, if the second remaining process count is less than the second remaining process warning count (step S51: Yes), the first process control function 95 of the control circuit 90 determines whether there is an item set to which the measurement item for which the measurement instruction was input is assigned (step S53). Then, in step S53, if there is an item set to which the measurement item for which the measurement instruction was input is assigned (step S53: Yes), the first process control function 95 of the control circuit 90 acquires item set information of the item set to which the measurement item for which the measurement instruction was input is assigned (step S55). Specifically, the first process control function 95 acquires item set information of the item set to which the measurement item for which the measurement instruction was input is assigned from the item set information storage circuit 83.

[0090] 8, the first process control function 95 of the control circuit 90 determines whether there is an item set with a higher priority than the priority of the measurement item (step S57). Specifically, the first process control function 95 compares the priority information in the item information acquired in step S47 with the priority information in the item set information acquired in step S55 to determine whether there is an item set with a higher priority than the priority of the measurement item for which measurement has been instructed.

[0091] Then, in step S57, if there is an item set with a higher priority than the priority of the measurement item (step S57: Yes), the first process control function 95 of the control circuit 90 judges whether there is a measurement instruction for the high priority item set (step S59). If there is an item set with a higher priority than the priority of the measurement item for which a measurement instruction has been given (step S59: Yes), the process returns to step S51 and waits while repeating the processes from step S51 to step S59. That is, the first process control function 95 waits for the measurement of the measurement item for which a measurement instruction has been input until the remaining amount of the reagent corresponding to the measurement item exceeds the second remaining process warning number by replenishing the reagent in step S51, or until the priority of the measurement item for which a measurement instruction has been given in step S57 has been changed so that the priority of the measurement item becomes higher than the priority of the item set, or until the measurement of the item set with a higher priority than the priority of the measurement item for which a measurement instruction has been given in step S59 has been completed.

[0092] On the other hand, if the second remaining process number is not less than the second remaining process warning number in step S51 (step S51: No), if there is no item set to which the measurement item for which a measurement instruction has been input is assigned (step S53: No), if there is no item set with a higher priority than the measurement item for which a measurement instruction has been input in step S57 (step S57: No), or if there is no item set with a higher priority than the measurement item for which a measurement instruction has been input in step S59 (step S59: No), the first process control function 95 of the control circuit 90 executes the measurement of the measurement item (step S61). Specifically, the first process control function 95 starts the control of the analysis mechanism 20 by the system control function 91 to execute the measurement of the measurement item for which a measurement instruction has been input. Then, when the process of step S43 has been executed or the process of step S61 has been executed, the measurement process according to this embodiment ends.

[0093] As described above, according to the automated analyzer 10 of this embodiment, priority information is set for each of the item information and item set information, and the processing of item sets and measurement items is controlled based on the priority information, so that when the number of remaining measurement items to be processed is decreasing, i.e., when the number of remaining measurement items to be processed falls below the second remaining processing warning number, the automated analyzer 10 can process item sets or measurement items with higher priority, without the user having to decide the order in which to process the measurement items and item sets. This allows samples to be processed efficiently while reducing the burden on the user of deciding the order in which to process the measurement items and item sets.

[0094] Third Embodiment In the automated analyzer 10 according to each of the above-described embodiments, it is also possible to control the display circuitry 61 to display an item set view screen for checking the multiple measurement items assigned to an item set for each item set, and / or an item view screen for checking the item sets to which the measurement items are assigned for each measurement item. Below, the third embodiment will be described using the above-described first embodiment as an example where this modified example is applied, but this modified example can be similarly applied to the other embodiments.

[0095] Fig. 9 is a block diagram showing an example of the functional configuration of an automatic analyzer 10 according to a third embodiment, and corresponds to Fig. 1 in the above-mentioned first embodiment. As shown in Fig. 9, in the automatic analyzer 10 according to this embodiment, a control circuit 90 is configured by additionally providing a display control function 96.

[0096] The display control function 96, like the other functions, is realized by the control circuit 90 reading and executing a program stored in the memory circuit 80. The display control function 96 corresponds to the display control unit in this embodiment.

[0097] The display control function 96 controls the display circuit 61 to display an item set view screen for checking the multiple measurement items assigned to the item set for each item set. The display control function 96 also controls the display circuit 61 to display an item view screen for checking the item sets to which the measurement items are assigned for each measurement item. The display control function 96 also switches between the item set view screen and the item view screen based on a user's operation. Furthermore, the display control function 96 also switches between the item set view screen or the item view screen and a reagent information screen for checking reagent information related to the reagent corresponding to the measurement item based on a user's operation. The item set view screen corresponds to the first confirmation screen in this embodiment, the item view screen corresponds to the second confirmation screen in this embodiment, and the reagent information screen corresponds to the third confirmation screen in this embodiment.

[0098] Next, examples of the configuration of each of the item set view screen, item view screen, and reagent information screen and an example of a method of moving to each screen will be described with reference to Figs. 10 to 13. Fig. 10 is a diagram showing an example of a reagent management screen displayed on the display circuit 61 of the automatic analyzer 10 according to this embodiment, and corresponds to Fig. 4 in the above-mentioned first embodiment. Fig. 11 is a diagram showing an example of an item set view screen displayed on the display circuit 61 of the automatic analyzer 10 according to this embodiment. Fig. 12 is a diagram showing an example of an item view screen displayed on the display circuit 61 of the automatic analyzer 10 according to this embodiment. Fig. 13 is a diagram showing an example of a reagent information screen displayed on the display circuit 61 of the automatic analyzer 10 according to this embodiment.

[0099] As shown in Fig. 10, the reagent management screen S2a displayed on the display circuit 61 is additionally configured with an item set tab T2 in addition to the reagent tab T1. The user can move to an item set screen including an item set view screen and an item view screen by selecting the item set tab T2 via the input interface 50. Note that the method of moving from the reagent management screen S2a to the item set screen is not limited to the method of having the user select a tab. In other words, the method of moving from the reagent management screen S2a to the item set screen is arbitrary, and a button for moving to the item set screen or the like may be displayed.

[0100] Next, the item set view screen S4 will be described. In this embodiment, when an item set tab is selected on the reagent management screen S2a, the screen moves to the item set view screen S4. As shown in FIG. 11, the item set view screen S4 in the item set screen displayed on the display circuit 61 displays a plurality of measurement items assigned to the item sets so that each item set can be confirmed. The item set view screen S4 shown in FIG. 11 displays an item set X, an item set Y, and an item set Z, and it can be confirmed that item set X is assigned to item B, item A, and item C, item set Y is assigned to item D, item E, and item F, and item set Z is assigned to item A, item D, and item E. Here, the item refers to a measurement item. On this item set view screen S4, the user can move from the item set view screen S4 to the item view screen by pressing the item view button B1 via the input interface 50. In addition, on this item set view screen S4, the user can select any of the measurement items assigned to the item set via the input interface 50 and then press the reagent information button B2 to move to the reagent information screen for the reagent corresponding to that measurement item.

[0101] Next, the item view screen S5 will be described. In this embodiment, the item view button B1 on the item set view screen S4 is pressed to move from the item set view screen S4 to the item view screen S5. As shown in FIG. 12, the item view screen S5 in the item set screen displayed on the display circuit 61 displays the item sets to which the measurement items are assigned so that they can be confirmed for each measurement item. The item view screen S5 shown in FIG. 12 displays item A and item B, and it can be confirmed that item A is assigned to item set X, item set V, and item set Z, and item B is assigned to item set X, item set V, and item set W. On this item view screen S5, the user can move from the item view screen S5 to the item set view screen S4 by pressing the item set view button B3 via the input interface 50. Also, on this item view screen S5, the user can move to the reagent information screen of the reagent corresponding to the measurement item by pressing the reagent information button B2 with one of the measurement items selected via the input interface 50.

[0102] Next, the reagent information screen S6 will be described. As shown in FIG. 13, the reagent information screen S6 displayed on the display circuit 61 displays reagent information on the reagent corresponding to the measurement item so that it can be confirmed. The reagent information screen S6 shown in FIG. 13 displays reagent information on the reagent corresponding to the item A. Since the item A is a two-reagent system, the first reagent name of the item A, "ReagentA-1", the expiration date of the first reagent of the item A, the remaining reagent amount of the first reagent of the item A, and the threshold value for the expiration date and the threshold value for the remaining reagent amount as warning information set for the first reagent of the item A are displayed, and the second reagent name of the item A, "ReagentA-2", the expiration date of the second reagent of the item A, the remaining reagent amount of the second reagent of the item A, and the threshold value for the expiration date and the threshold value for the remaining reagent amount as warning information set for the second reagent of the item A are displayed. In this reagent information screen S6, the user can move from the reagent information screen S6 to the item set view screen S4 by pressing the item set view button B3 via the input interface 50. Furthermore, on this reagent information screen S6, the user can press the item view button B1 via the input interface 50 to move from the reagent information screen S6 to the item view screen S5.

[0103] As described above, according to the automatic analyzer 10 of this embodiment, it is possible to check the measurement items assigned to an item set, the item set to which the measurement items are assigned, and reagent information regarding the reagents corresponding to the measurement items. This allows the user to more easily manage the item sets, measurement items, and reagent information, thereby reducing the burden on the user.

[0104] In the third embodiment described above, the display control function 96 can also control the display circuitry 61 to display the first remaining number of processes corresponding to the item set on the item set view screen S4. FIG. 14 is a diagram showing another example of the item set view screen displayed on the display circuitry 61 of the automated analyzer 10 according to the third embodiment, and corresponds to FIG. 11. As shown in FIG. 14, the item set view screen S4a displays the first remaining number of processes for each item set. In this way, by displaying the first remaining number of processes on the item set view screen S4a, the user can check the number of times that the item set can be measured. In the example shown in FIG. 14, the first remaining number of processes is displayed, but information on the order status of each item set may be displayed together with or instead of the first remaining number of processes. Here, the information on the order status of each item set is information such as the number of orders for each item set.

[0105] In addition, in the third embodiment described above, selecting the item set tab T2 on the reagent management screen S2a moves to the item set view screen S4, but selecting the item set tab T2 on the reagent management screen S2a may also move to the item view screen S5.

[0106] [Fourth embodiment] In the automated analyzer 10 according to each of the above-described embodiments, it is also possible to select a measurement item and / or an item set, and temporarily disable the processing of the selected measurement item and / or item set. Below, the fourth embodiment will be described using the above-described first embodiment as an example in which this modified example is applied, but this modified example can be similarly applied to the other embodiments.

[0107] Fig. 15 is a block diagram showing an example of the functional configuration of an automatic analyzer 10 according to a fourth embodiment, and corresponds to Fig. 1 in the first embodiment described above. As shown in Fig. 15, in the automatic analyzer 10 according to this embodiment, the control circuit 90 is configured by additionally including a display control function 96, a selection function 97, and a second process control function 98. The display control function 96, the selection function 97, and the second process control function 98 are all realized by the control circuit 90 reading and executing a program stored in the memory circuitry 80, like the other functions.

[0108] The display control function 96 changes the display mode of the measurement item and / or item set selected by the selection function 97 in response to user input on the item set view screen S4 or item view screen S5. Changing the display mode is, for example, changing the color of the characters or the color of the background. Other functions and configurations are equivalent to those of the display control function 96 in the third embodiment described above, and therefore description thereof will be omitted.

[0109] The selection function 97 selects a measurement item and / or an item set in response to a user input. In this embodiment, the selection function 97 selects a measurement item and / or an item set in response to a user input via the input interface 50 on the item set view screen S4 or the item view screen S5. The selection function 97 corresponds to the selection unit in this embodiment.

[0110] The second process control function 98 controls the processing of the measurement items and item sets so as to restrict the processing of the measurement items and / or item sets selected by the selection function 97. Specifically, the second process control function 98 controls the measurement processing of the measurement items and / or item sets so as not to execute the measurement processing of the measurement items and / or item sets selected by the selection function 97. In other words, the second process control function 98 controls the measurement processing of the measurement items and item sets so as to invalidate the measurement items and / or item sets selected by the selection function 97. The second process control function 98 corresponds to the second process control unit in this embodiment.

[0111] Next, with reference to Figs. 16 to 18, an example of a method for selecting a measurement item and / or an item set to be disabled on the item set view screen or item view screen and a display mode of the selected measurement item and / or item set will be described. Fig. 16 is a diagram showing an example of a display mode of the item set view screen when an item set to be disabled is selected in the automatic analysis device 10 according to this embodiment. Fig. 17 is a diagram showing an example of a display mode of the item view screen when an item set to be disabled is selected in the automatic analysis device 10 according to this embodiment. Fig. 18 is a diagram showing an example of a display mode of the item view screen when a measurement item to be disabled is selected in the automatic analysis device 10 according to this embodiment.

[0112] First, a case where an item set is invalidated will be described. As shown in FIG. 16, the item set view screen S4b displayed on the display circuit 61 is additionally configured with an item set invalidation button B4 in comparison with the item set view screen S4 shown in FIG. 11. That is, the item set can be invalidated in the item set view screen S4b shown in FIG. 16. When the user presses the item set invalidation button B4 and presses an item set via the input interface 50 in this item set view screen S4b, or when the user presses an item set and presses the item set invalidation button B4, the selection function 97 selects the item set. Then, the display control function 96 changes the display mode of the item set selected by the selection function 97. In the example shown in FIG. 16, the item set Z is selected, so the background color of the item set Z is changed. Therefore, the invalidated item set can be confirmed in the item set view screen S4b.

[0113] When switching to the item view screen S5a with this item set Z in a disabled state, the display mode of item set Z within item A on the item view screen S5a will change as shown in Fig. 17. In other words, the disabled item set can be confirmed even on the item view screen S5a.

[0114] Next, a case where a measurement item is disabled will be described. As shown in FIG. 18, the item view screen S5a displayed on the display circuit 61 is additionally configured with an item disable button B5 in comparison with the item view screen S5 shown in FIG. 12. That is, in the example shown in FIG. 18, the measurement item can be disabled in the item view screen S5a. When the user presses the item disable button B5 and presses a measurement item via the input interface 50 in this item view screen S5a, or when the user presses a measurement item and presses the item disable button B4, the selection function 97 selects the measurement item. Then, the display control function 96 changes the display mode of the measurement item selected by the selection function 97. In the example shown in FIG. 18, the measurement item of item B is selected, so the background color of item B is changed. Therefore, the disabled measurement item can be confirmed in the item view screen S5a. Note that, similarly to the case of disabling an item set, the disabling of the measurement item can also be confirmed in the item set view screen S4b.

[0115] As shown in Figs. 16 to 18, the measurement items and / or item sets can be disabled, and the disabled measurement items and / or item sets are managed, for example, in a management table. Fig. 19 is a diagram showing an example of a management table for managing disabled measurement items and / or item sets in the memory circuit 80 of the automatic analyzer 10 according to this embodiment. In the example shown in Fig. 19, the management table MT1 holds management numbers associated with the disabled measurement items or item sets. In addition, the management table MT1 shown in Fig. 19 registers item set Z and item B as the disabled measurement items or item sets. Note that the management table MT1 may include other information. This management table MT1 is stored, for example, in the memory circuit 80.

[0116] FIG. 20 is a flow chart illustrating the contents of the measurement process executed by the automatic analyzer 10 shown in FIG. 15. In this measurement process, the automatic analyzer 10 executes the measurement of the item set or measurement item for which a measurement instruction has been issued, while restricting the processing of the measurement item and / or item set selected by the selection function 97. For example, the measurement process is a process that is executed when a measurement instruction for an item set or a measurement instruction for a measurement item is input. In addition, this measurement process is a process that is executed for each measurement instruction for an item set or measurement item. Note that the process of step S31 is similar to the measurement process in the second embodiment described above, and therefore a description thereof will be omitted.

[0117] Then, if a measurement instruction for the item set is input in step S31 (step S31: Yes), the second process control function 98 of the control circuit 90 determines whether or not processing of the item set is restricted (step S71). Specifically, the second process control function 98 refers to the management table MT1 stored in the memory circuit 80 to determine whether or not processing of the item set for which a measurement instruction was input in step S31 is restricted.

[0118] If the processing of the item set is restricted in step S71 (step S71: Yes), the second processing control function 98 of the control circuit 90 waits and repeats the processing of step S71 until the restriction on the processing of the item set is lifted. On the other hand, if the processing of the item set is not restricted in step S71 (step S71: No), the second processing control function 98 of the control circuit 90 acquires item set information. Note that the processing of step S13 is similar to the measurement processing in the second embodiment described above, and therefore will not be described.

[0119] After this step S13, as shown in FIG. 20, the second process control function 98 of the control circuit 90 judges whether the process of the measurement item of the item set is restricted (step S73). Specifically, the second process control function 98 judges whether the process of the measurement item assigned to the item set in the item set information acquired in step S13 is restricted by referring to the management table MT1 stored in the memory circuit 80. Then, in step S71, if the process of the item set is restricted (step S71: Yes), the second process control function 98 of the control circuit 90 waits by repeating the process of step S73 until the restriction on the process of the measurement item is lifted. On the other hand, in step S73, if the process of the measurement item is not restricted (step S73: No), the second process control function 98 of the control circuit 90 acquires the item information (step S15). Note that the process of steps S17 and S43 after this step S15 is the same as the measurement process in the second embodiment described above, and therefore the description will be omitted. Moreover, the process of step S45 is similar to the measurement process in the second embodiment described above, and therefore a description thereof will be omitted.

[0120] In step S45, if a measurement instruction for the measurement item is input (step S45: Yes), the second process control function 98 of the control circuit 90 judges whether the process of the measurement item is restricted (step S75). Specifically, the second process control function 98 judges whether the process of the measurement item for which the measurement instruction is input is restricted by referring to the management table MT1 stored in the memory circuit 80. Then, in step S75, if the process of the measurement item is restricted (step S75: Yes), the second process control function 98 of the control circuit 90 waits by repeating the process of step S75 until the restriction on the process of the measurement item is lifted. On the other hand, in step S75, if the process of the measurement item is not restricted (step S75: No), the second process control function 98 of the control circuit 90 acquires item information (step S47). Note that the processes of steps S47, S49, and S61 after this step S47 are the same as the measurement process in the second embodiment described above, and therefore will not be described. Then, when the process of step S43 is executed, or when the process of step S61 is executed, the measurement process according to this embodiment ends.

[0121] As described above, the automated analyzer 10 according to this embodiment controls the processing of the measurement items and / or item sets by selecting the measurement items and / or item sets for which processing is to be disabled and restricting the processing of the selected measurement items and / or item sets, so that the user can disable the processing of low-priority item sets or measurement items and have the automated analyzer process high-priority item sets or measurement items. This allows samples to be processed efficiently.

[0122] In the above-mentioned fourth embodiment, the management table MT1 is used to manage the disabled measurement items and / or item sets, but the method of managing the disabled measurement items and / or item sets is not limited to this. That is, any method of managing the disabled measurement items and / or item sets may be used, and for example, the item information or item set information corresponding to the disabled measurement items or item sets may include information on disabling indicating whether or not they have been disabled. In this case, in the measurement process according to the above-mentioned fourth embodiment, the item information or item set information corresponding to the measurement items or item sets for which a measurement instruction has been input may be obtained, and it may be determined whether or not the processing of the measurement items or item sets is restricted based on the information on disabling included in the item information or item set information.

[0123] Fifth embodiment In each of the above-described embodiments, the automatic analyzer 10 stores item information and item set information, calculates the first remaining number of processes, and outputs a warning, but these are not limited to being performed by the automatic analyzer 10. In the fifth embodiment, a management device connected to one or more automatic analyzers via a network may store item information and item set information of each of the one or more automatic analyzers, calculate the first remaining number of processes, and output a warning. Below, the fifth embodiment will be described taking as an example a case where this modification is applied to the above-described first embodiment, but this modification can be similarly applied to the other embodiments.

[0124] FIG. 21 is a block diagram showing the overall configuration of an automatic analysis system according to a fifth embodiment. As shown in FIG. 21, an automatic analysis system 1 according to this embodiment is configured to include three automatic analyzers 10a and a management device 100 capable of communicating with each of the three automatic analyzers 10a. In the example shown in FIG. 21 in this embodiment, the automatic analysis system 1 is configured to include three automatic analyzers 10a, but the number of automatic analyzers 10a is not limited to this. In other words, the number of automatic analyzers 10a is arbitrary, and one or two automatic analyzers 10a may be capable of communicating with the management device 100, or four or more automatic analyzers 10a may be capable of communicating with the management device 100.

[0125] The automatic analyzer 10a according to this embodiment is an apparatus that uses a sample and a reagent corresponding to a measurement item of the sample to analyze a mixture of the sample and the reagent. The automatic analyzer 10a performs measurement of the measurement items based on measurement instructions such as a test order, reagent information, item information, and item set information transmitted from the management device 100. The automatic analyzer 10a also stores reagents corresponding to the sample to be measured in a reagent repository provided in the automatic analyzer 10a. The automatic analyzer 10a communicates with the management device 100 and transmits reagent information, which is information on the reagents stored in the reagent repository, to the management device 100.

[0126] The management device 100 is communicably connected to one or more automatic analyzers 10a and manages the one or more automatic analyzers 10a. The management device 100 is, for example, a computer or the like that can function as middleware in an in-hospital system such as a clinical test information system or the automatic analysis system 1, which is responsible for measuring samples and managing reagents. In this embodiment, the management device 100 receives test order information related to a test order, and transmits reagent information, item set information, or item information based on the test order information to the automatic analysis device 10a. In addition, the management device 100 acquires reagent information including reagent remaining amount information related to the remaining amount of reagent from one or more automatic analysis devices 10a, calculates a first remaining processing number, and outputs a warning when the remaining amount of reagent stored in the reagent repository of the automatic analysis device 10a is low.

[0127] Fig. 22 is a block diagram showing an example of the functional configuration of an automatic analyzer 10a according to a fifth embodiment, and corresponds to Fig. 1 in the first embodiment described above. As shown in Fig. 22, the automatic analyzer 10a according to this embodiment is equivalent to the automatic analyzer 10 according to the first embodiment described above, except that it does not include the item information storage circuit 81, the reagent information storage circuit 82, the item set information storage circuit 83, the acquisition function 92, the calculation function 93, and the warning function 94. For this reason, a detailed description of the automatic analyzer 10a will be omitted here.

[0128] Fig. 23 is a block diagram showing an example of a functional configuration of a management device 100 according to the fifth embodiment. As shown in Fig. 23, the management device 100 according to this embodiment is configured to include, for example, an input interface 101, an output interface 102, a communication interface 103, a memory circuit 104, and a processing circuit 105, which are connected to each other via an internal bus.

[0129] The input interface 101 is connected to the processing circuit 105, and converts an input operation received from a user into an electrical signal and outputs the signal to the processing circuit 105. The input interface 101 receives, for example, a setting of a first remaining process warning number included in the item set information and a setting of a second remaining process warning number included in the item information. The input interface 101 is realized by, for example, a mouse, a keyboard, and a touchpad on which an instruction is input by touching the operation surface. In this embodiment, the input interface 101 is not limited to an interface having physical operation parts such as a mouse and a keyboard. For example, an example of the input interface 50 also includes an electrical signal processing circuit that receives an electrical signal corresponding to an operation instruction input from an external input device provided separately from the management device 100 and outputs the electrical signal to the processing circuit 105.

[0130] The output interface 102 is connected to the processing circuit 105 and outputs various information from the processing circuit 105. The output interface 60 is realized by, for example, a display circuit, a printed circuit, an audio device, and the like. The display circuit includes, for example, an organic EL display, a liquid crystal display, a CRT display, an LED display, a plasma display, and the like. This display circuit corresponds to the display unit in this embodiment. The display circuit also includes a processing circuit that converts data representing a display object into a video signal and outputs the video signal to the outside. The printed circuit includes, for example, a printer, and the like. The printed circuit also includes an output circuit that outputs data representing a print object to the outside. The audio device includes, for example, a speaker, and the like. The audio device also includes an output circuit that outputs an audio signal to the outside.

[0131] The communication interface 103 is realized by a communication interface for performing wireless communication or wired communication. In this embodiment, for example, it is configured by a communication interface for a wireless LAN (Local Area Network), and can transmit and receive information such as reagent information, item information, and item set information to and from one or more automatic analyzers 10a by wireless communication.

[0132] The storage circuit 104 is composed of a processor-readable storage medium such as a magnetic or optical storage medium, or a semiconductor memory. The storage circuit 104 stores a processing program executed by the processing circuit 105. The storage circuit 104 shown in FIG. 23 is composed of an item information storage circuit 1041, a reagent information storage circuit 1042, and an item set information storage circuit 1043. The item information storage circuit 1041, the reagent information storage circuit 1042, and the item set information storage circuit 1043 correspond to the item information storage circuit 81, the reagent information storage circuit 82, and the item set information storage circuit 83 in the automatic analyzer 10 according to the first embodiment described above, respectively, and have substantially the same functions. The item information storage circuit 1041, the reagent information storage circuit 1042, and the item set information storage circuit 1043 may be realized by a single storage device or may be realized by multiple storage devices. The storage circuit 104 corresponds to the storage unit according to this embodiment. Note that the memory circuit 104 does not necessarily have to be realized by a single storage device, but can be realized by a plurality of storage devices, for example.

[0133] The processing circuit 105 controls each component of the management device 100. For example, the processing circuit 105 is realized by a processor. In particular, in this embodiment, the processing circuit 105 realizes an acquisition function 1051, a calculation function 1052, and a warning function 1053 by, for example, executing a processing program. In this embodiment, the acquisition function 1051, the calculation function 1052, and the warning function 1053 are realized by a single processor, but this is not limited to this. For example, a processing circuit may be configured by combining multiple independent processors, and the acquisition function 1051, the calculation function 1052, and the warning function 1053 may be realized by each processor executing a control program. The acquisition function 1051, the calculation function 1052, and the warning function 1053 are equivalent to the acquisition function 92, the calculation function 93, and the warning function 94 of the control circuit 90 of the automatic analyzer 10a in the first embodiment described above, respectively. The acquisition function 1051, the calculation function 1052, and the warning function 1053 correspond to the acquisition unit, the calculation unit, and the warning unit in this embodiment.

[0134] Specifically, the acquisition function 1051 in the processing circuitry 105 of the management device 100 acquires reagent information, item information, and item set information from the memory circuitry 104 etc. in response to the test order information. The acquisition function 1051 also acquires reagent information in a reagent storage of the automatic analyzer 10a from the automatic analyzer 10a and stores the information in the memory circuitry 104. The calculation function 1052 calculates a first remaining processing number indicating the remaining processing number of the item set based on the reagent remaining amount information and item set information included in the reagent information.

[0135] The warning function 1053 outputs a warning when the first remaining processing number calculated by the calculation function 1052 falls below the remaining processing warning number in the item set information. The warning function 1053 according to this embodiment may output a warning to the output interface 102 of the management device 100, or may output a warning to the output interface 60 of the automatic analyzer 10a by communicating with the automatic analyzer 10a via the communication interface 103.

[0136] As described above, in the automatic analysis system 1 of this embodiment, the management device 100 stores item set information for an item set to which multiple measurement items are assigned, calculates a first remaining process number indicating the remaining process number for the item set based on the reagent remaining amount information and item set information acquired from the automatic analysis device 10a, and outputs a warning if the first remaining process number falls below the first remaining process warning number for the item set.Therefore, it is possible to manage the remaining process number for each set, with multiple measurement item groups as one set, and sample processing can be performed efficiently.

[0137] Furthermore, in the automated analysis system 1 according to this embodiment, one management device 100 manages reagent information, such as remaining reagent amount information, of multiple automated analyzers 10a. This makes it possible to centrally manage reagent information in the reagent storage chambers of multiple automated analyzers in the same facility, and item set information and item information that can be measured by multiple automated analyzers in the same facility, without having to set item set information in each of the multiple automated analyzers 10a or manage reagent information in each of the multiple automated analyzers 10a.

[0138] [Modifications of the first to fifth embodiments] Although the application of the automatic analyzers 10 and 10a according to the first to fifth embodiments to automatic analyzers that perform biochemical tests has been described above, the present invention is not limited to this. That is, the first to fifth embodiments can also be applied to automatic analyzers that perform blood coagulation analysis tests.

[0139] The term "processor" used in the above description means a circuit such as a central processing unit (CPU), a graphics processing unit (GPU), an application specific integrated circuit (ASIC), a programmable logic device (e.g., a simple programmable logic device (SPLD), a complex programmable logic device (CPLD), and a field programmable gate array (FPGA)). The processor realizes its function by reading and executing a program stored in a memory circuit. Instead of storing a program in a memory circuit, the processor may be configured to directly incorporate the program in the circuit. In this case, the processor realizes its function by reading and executing the program incorporated in the circuit. The processor is not limited to being configured as a single processor circuit, and may be configured as a single processor by combining multiple independent circuits to realize its function. Furthermore, multiple components may be integrated into a single processor to realize its function.

[0140] Although several embodiments have been described above, these embodiments are presented only as examples and are not intended to limit the scope of the invention. The novel device and method described in this specification can be implemented in various other forms. In addition, various omissions, substitutions, and modifications can be made to the forms of the device and method described in this specification without departing from the spirit of the invention. The appended claims and their equivalents are intended to include such forms and modifications that fall within the scope and spirit of the invention. [Explanation of symbols]
