Description

[Technical Field]

[0001] The present disclosure relates to an automated analyzer. [Background technology]

[0002] A known blood coagulation analysis involves injecting a reagent into a reaction vessel (hereinafter referred to as a "cuvette") into which a specimen such as blood components or urine has been dispensed, and measuring the scattered or transmitted light when light is irradiated onto the vessel, thereby analyzing the coagulation and fibrinolytic functions of the specimen.

[0003] Known techniques for such blood coagulation analysis include a method for measuring clotting time and a colorimetric method. The former is a method in which a cuvette containing a sample and a reagent is irradiated with light and the clotting time of each item is calculated from the process of change in scattered light intensity. The latter is a method in which a cuvette containing a sample and a reagent is irradiated with light of a specific wavelength, the absorbance is measured, and the concentration or activity of each item is calculated from the absorbance after a specified time period or the amount of change in absorbance within a specified time period. Note that the colorimetric method is sometimes called an absorbance measurement method.

[0004] Japanese Patent Laid-Open Publication No. 2017-111050 (Patent Document 1) discloses an automatic analyzer that analyzes a specimen contained in a specimen container using a reagent contained in a reagent container. The automatic analyzer disclosed in Japanese Patent Laid-Open Publication No. 2017-111050 includes a measurement unit, a transport unit, and an information processing unit. The information processing unit is a personal computer or the like, and includes a control unit, an input unit (keyboard, mouse, touch panel, etc.), and an output unit (monitor, etc.), and accepts user operations via the input unit and outputs measurement results received from the measurement unit and information based on signals received from the measurement unit via the output unit.

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2017-111050 Summary of the Invention [Problem to be solved by the invention]

[0006] In this type of automated analyzer, the output unit displays not only measurement results but also reagent information, sample information, analysis schedules, analysis history, and various settings (parameters) for the automated analyzer. When the automated analyzer is powered on, the input unit accepts not only user operations on the application program for performing automated analysis, but also user operations on the system program for managing the automated analyzer system. This allows users to edit or delete reagent information, sample information, analysis schedules, analysis history, parameters, and the like, and to save this data to any recording medium. Furthermore, users can edit or delete configuration files for the application program. Because users can freely perform operations such as editing, deleting, and saving, there is a risk of personal information being leaked or the application program, and ultimately the automated analyzer, being damaged.

[0007] The present disclosure has been made in consideration of the above-described circumstances, and one of its objects is to provide an automatic analyzer that can prevent leakage of personal information and breakdowns in the device. [Means for solving the problem]

[0008] The automated analyzer of the present disclosure includes a reception unit that receives user operations, a memory unit that stores a system program for managing the automated analyzer system and an application program that is executed under the control of the system program and performs automated analysis, and a control unit that executes the system program and the application program stored in the memory unit. The control unit limits the state in which the reception unit can receive user operations for the system program while the application program is running. [Effects of the Invention]

[0009] According to the present disclosure, the state in which the accepting unit can accept user operations for a system program while an application program is running is limited, thereby preventing leakage of personal information and device failure. [Brief explanation of the drawings]

[0011] Each embodiment will be described in detail below with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference numerals and description thereof will not be repeated.

[0012] [Embodiment 1] An automatic analyzer according to this embodiment (hereinafter simply referred to as "analyzer") is configured to dispense a specimen and a reagent into a reaction vessel using a dispensing nozzle and optically measure the reaction state in the reaction vessel. Hereinafter, the dispensing nozzle and specimen will be referred to as a "probe" and a "sample," respectively. Examples of samples that can be used include blood components and urine. In this embodiment, a disposable cuvette (e.g., cuvette 100 shown in FIG. 3, which will be described later) is used as the reaction vessel of the analyzer. An overview of the analyzer will be described below with reference to FIGS. 1 to 5. The automatic analyzer may be, for example, a (general-purpose) clinical chemistry analyzer, electrolyte analyzer, blood gas analyzer, immunoserological test apparatus, blood test apparatus, blood cell counter, blood coagulation analyzer, or urinalysis apparatus, and is an apparatus having a mechanism for transporting containers such as specimens.

[0013] 1 is a diagram showing a control system of an analysis device 1000 according to Embodiment 1. The analysis device 1000 includes a control device 500, an input device 610, an output device 620, a sample rack 800, a reagent refrigerator 700, a cuvette supplying device 110, a sample dispensing device 20, a cuvette transporting device 120, a reagent dispensing device 10, a stirring device 200, and a measuring device 300.

[0014] The control device 500 controls the input device 610 , output device 620 , sample rack 800 , reagent cooler 700 , cuvette supply device 110 , sample dispensing device 20 , cuvette transport device 120 , reagent dispensing device 10 , stirring device 200 , and measuring device 300 .

[0015] The control device 500 includes a CPU (Central Processing Unit) 510, a RAM (Random Access Memory) 520, and a storage device 530. The CPU 510 loads into the RAM 520 a system program 531 and an application program 532 stored in the storage device 530 and executes them. The system program 531 is a program for managing the system of the analysis device 1000, and the application program 532 is a program that is executed under the control of the system program 531 and performs automatic analysis. The application program 532 describes the procedures of various processes executed by the CPU 510.

[0016] The storage device 530 stores a system program 531 and an application program 532, as well as various data used in various processes (e.g., reagent information, sample information, analysis schedule, analysis history, parameters, etc.). The reagent information is information about the reagents stored in the reagent refrigerator 700. The sample information is information about the samples stored in the sample rack 800. The analysis schedule is the order in which the analyses are performed. In order to efficiently analyze all reserved samples, the analyzer 1000 determines the analysis schedule based on the analysis items for each sample and the availability of each port, which will be described later. This allows the analyzer 1000 to analyze multiple samples in parallel. The analysis history is information including the progress of the analysis and the measurement results, and is updated sequentially as the analysis progresses. The parameters are various settings for the analyzer 1000. The control device 500 executes various processes in the analyzer 1000 in accordance with these programs and various data. Note that the processes are not limited to being performed by software, but can also be performed by dedicated hardware (electronic circuits).

[0017] The input device 610 functions as a reception unit that receives operations by the user. The input device 610 is, for example, a keyboard, a mouse, a touch panel, or the like. When the input device 610 receives an operation by the user, it outputs a signal corresponding to the operation to the control device 500. The output device 620 functions as a display unit that displays a screen provided by the application program 532. The output device 620 is, for example, a monitor, a touch panel display, or the like. When a request is received from the control device 500, the output device 620 displays a predetermined image in accordance with the request. The input device 610 and the output device 620 may be separate or integrated. An example of an integrated input device 610 and output device 620 is a touch panel display.

[0018] The sample rack 800 accommodates sample containers containing samples to be analyzed. The sample containers are provided with an identifier (e.g., a barcode, a QR code (registered trademark), a data matrix, etc.) that can identify the sample in the sample container. Information about the sample in the sample container (e.g., patient information, sample ID, analysis items, etc.) is embedded in the identifier provided to the sample container.

[0019] The reagent refrigerator 700 stores and keeps cool reagent containers containing reagents used in analysis. The reagent containers are affixed with identifiers (for example, barcodes, QR codes, data matrices, etc.) that can identify the reagents in the reagent containers. The identifiers affixed to the reagent containers contain embedded information about the reagent containers and the reagents in the reagent containers (for example, the type of reagent (analysis item), information indicating whether the reagent is a one-reagent system or a two-reagent system, the reagent lot number, the reagent expiration date, the reagent serial number, the shape of the reagent container, the capacity of the reagent container, the number of analyses possible, etc.).

[0020] The cuvette supplying device 110 supplies an empty cuvette to a position (sample dispensing port) where the sample dispensing device 20 can dispense a sample. The sample dispensing device 20 dispenses the sample into the cuvette. The cuvette transporting device 120 transports the cuvette into which the sample has been dispensed. The reagent dispensing device 10 dispenses a reagent into the cuvette into which the sample has been dispensed. The stirring device 200 stirs the contents of the cuvette under predetermined conditions (e.g., stirring speed and stirring time). The measuring device 300 performs a predetermined measurement on the contents of the cuvette. In this embodiment, the measuring device 300 has a light source and a photodetector, irradiates the contents of the cuvette with light from the light source, and measures the reaction state in the cuvette based on changes in the amount of light detected by the photodetector.

[0021] FIG. 2 is a diagram showing a configuration for transferring and discarding cuvettes, and stirring and measuring the contents of the cuvettes in the analyzer 1000 according to the first embodiment.

[0022] The analytical device 1000 includes a sample dispensing port P1. The cuvette supplying device 110 includes a cuvette storage unit 111 and a supply mechanism 112. The cuvette storage unit 111 can store a large number of cuvettes (for example, up to 1000). The supply mechanism 112 supplies the cuvettes stored in the cuvette storage unit 111 to the sample dispensing port P1. Details of the cuvette storage unit 111 and the supply mechanism 112 will be described with reference to FIG. 3.

[0023] The sample dispensing port P1 is placed at a position where the sample dispensing device 20 (FIG. 1) can dispense a sample into the cuvette. When a cuvette is set in the sample dispensing port P1, the sample dispensing device 20 dispenses the sample into the cuvette.

[0024] The cuvette transfer device 120 includes an arm 121 with a chuck (hereinafter simply referred to as "arm 121") and a drive device 122. The arm 121 has a chuck configured to be able to grip a cuvette. The arm 121 is configured to detachably hold the cuvette with the chuck. The drive device 122 operates the arm 121 to change the position of the chuck. The arm 121 and the drive device 122 will also be described in detail with reference to FIG. 3.

[0025] The analytical device 1000 further includes multiple ports through which cuvettes can be transferred by the cuvette transfer device 120, specifically, an agitation port P2, a photometry port P3, and a waste port P4. The photometry port P3 includes multiple scattering ports P3a and multiple colorimetric ports P3b. The sample dispensing port P1, the agitation port P2, the photometry port P3, and the waste port P4 are each provided with a port sensor that detects the presence or absence of a cuvette.

[0026] The stirring port P2 is disposed at the stirring position of the stirring device 200. When a cuvette is set in the stirring port P2, the stirring device 200 stirs the contents of the cuvette under predetermined conditions (for example, stirring speed and stirring time).

[0027] Each of the scattering port P3a and the colorimetric port P3b is disposed at a measurement position of the measurement device 300. Hereinafter, unless otherwise specified, each of the scattering port P3a and the colorimetric port P3b will be referred to as a "photometric port P3."

[0028] The measurement device 300 is configured to perform a predetermined measurement on the contents of a cuvette. In this embodiment, the measurement device 300 has a light source and a photodetector, and irradiates the contents of a cuvette set in one of the photometric ports P3 with light from the light source. The reaction state within the cuvette is measured based on changes in the amount of light detected by the photodetector. The measurement device 300 includes a light source and a photodetector for the scattering port P3a, and a light source and a photodetector for the colorimetric port P3b. The light source and the photodetector for the scattering port P3a can be a light-emitting diode and a photodiode, respectively. The photodetector for the scattering port P3a detects 90° scattered light (i.e., light scattered in a direction perpendicular to the direction of light irradiation). The light source and the photodetector for the colorimetric port P3b can be a halogen lamp and a photodiode, respectively. The photodetector for the colorimetric port P3b detects the amount of transmitted light.

[0029] The waste port P4 collects used cuvettes. The waste port P4 is connected via piping to a cuvette waste container 400. When a cuvette is placed in the waste port P4, the cuvette is guided to the cuvette waste container 400.

[0030] Fig. 3 is a plan view of the analysis table provided in the analysis device 1000 according to the first embodiment. Three mutually orthogonal axes (X-axis, Y-axis, and Z-axis) are shown in Fig. 3. Of the X-axis, Y-axis, and Z-axis, the X-axis indicates the width direction of the analysis device, the Y-axis indicates the depth direction of the analysis device, and the Z-axis indicates the vertical direction (i.e., the up-down direction). The direction indicated by the arrow on the Z-axis corresponds to "up," and the opposite direction corresponds to "down (i.e., the direction of gravity)."

[0031] 2 and 3, the cuvette storage unit 111 stores a plurality of cuvettes 100. A user can replenish the cuvettes 100 into the cuvette storage unit 111 through an inlet of the cuvette storage unit 111. The cuvettes 100 may be made of any material as long as they are light-transmitting, and for example, a material made of transparent acrylic may be used.

[0032] The supply mechanism 112 takes out the cuvettes 100 one by one from the cuvette storage unit 111 and supplies them to the sample dispensing port P1. The supply mechanism 112 may transport the cuvettes 100 in any manner, including, for example, a slide system (gravity system), a belt conveyor system, a roller system, or a slide system. The supply mechanism 112 receives the detection result of the port sensor of the sample dispensing port P1, and supplies the next cuvette 100 to the sample dispensing port P1 when the sample dispensing port P1 becomes available. However, the present invention is not limited to this, and the supply mechanism 112 may also supply the cuvettes 100 to the sample dispensing port P1 in accordance with an instruction from the control device 500 (FIG. 1).

[0033] The arm 21 is a device (sample dispensing device 20 (FIG. 1)) for dispensing a sample aspirated from a sample aspirating port P21 into a cuvette 100 set in a sample dispensing port P1. The arm 21 includes a second probe 21a and an arm body 21b. As the arm body 21b rotates around a rotation axis 23a, the second probe 21a provided at the tip of the arm body 21b moves along an arc-shaped trajectory L2 on the XY plane.

[0034] As the arm body 21b rotates, the second probe 21a moves to the sample dispensing port P1, the sample suction port P21, the S port P22, and the washing port P23, which are provided on the track L2. The S port P22 includes detergent ports P22a and P22b, buffer solution ports P22c, P22d, and P22e, and depleted plasma ports P22f, P22g, P22h, and P22i.

[0035] A movable sample rack 800 (FIG. 1) is provided below the sample suction port P21. A plurality of sample containers containing samples such as blood components or urine are placed on the sample rack 800. Prior to dispensing a sample into a cuvette 100 set in the sample dispensing port P1, the sample rack 800 operates to position the sample container to be dispensed directly below the sample suction port P21. The CTS mechanism 24 is provided near the sample suction port P21. If the sample container to be dispensed has a cap, the CTS mechanism 24 pierces the cap with a piercer.

[0036] The arm 11 is a device (reagent dispensing device 10 (FIG. 1)) for dispensing a reagent aspirated from suction ports P11 and P12 into a target cuvette 100 set in photometry port P3. The arm 11 includes a first probe 11a and an arm body 11b. As the arm body 11b rotates around a rotation axis 13a, the first probe 11a attached to the tip of the arm body 11b moves along an arc-shaped trajectory L1 on the XY plane.

[0037] A reagent tray 710 on which a plurality of reagent containers A (or a plurality of detergent containers) are placed is provided below the suction ports P11, P12. The reagent tray 710 is provided inside the reagent refrigerator 700. The plurality of reagent containers A contain different reagents, and the plurality of detergent containers contain different detergents. The reagent tray 710 is a disc-shaped turntable, and by driving the turntable, the desired reagent container A (or detergent container) is positioned directly below the suction ports P11, P12. The first probe 11a aspirates the reagent (or cleaning liquid) in the reagent container A (or detergent container) positioned directly below the suction ports P11, P12.

[0038] As the arm body 11b rotates, the first probe 11a moves to each of the agitation port P2, scattering ports P3a, colorimetric ports P3b, suction ports P11 and P12, and washing port P13, which are provided on the track L1. The first probe 11a may be configured with two probes to prevent contamination between reagents. The reagent tray 710 may have an outer tray and an inner tray. The two probes aspirate the reagent (or washing liquid) on the outer tray and the reagent (or washing liquid) on the inner tray through the suction ports P11 and P12. The washing port P13 is a port for collecting used washing liquid, and although not shown, includes a water reservoir that collects water discharged from the first probe 11a to wash the outer surface of the probe tip, and a waste disposal unit that discards the liquid.

[0039] The arm 121 includes a chuck 121a and an arm body 121b. The chuck 121a is configured to be able to grip the cuvette 100. The chuck 121a may hold the cuvette 100 in any manner, and the chuck 121a may be a mechanical chuck, a magnetic chuck, or a vacuum chuck. The arm body 121b rotates around the rotation axis 122a, allowing the chuck 121a provided at the tip of the arm body 121b to move along an arc-shaped trajectory L1 on the XY plane.

[0040] As described above, the arms 11 and 121 have the same center of rotation. A sample dispensing port P1, an agitation port P2, a plurality of photometric ports P3 (a plurality of scattering ports P3a and a plurality of colorimetric ports P3b), a waste port P4, suction ports P11 and P12, and a washing port P13 are provided on the orbit L1. The arm 121 can move the chuck 121a to the sample dispensing port P1, the agitation port P2, each photometric port P3, and the waste port P4, and the arm 11 can move the first probe 11a to the suction ports P11 and P12, the washing port P13, the agitation port P2, and each photometric port P3.

[0041] Fig. 4 is a diagram for explaining the structures of arms 11 and 121 shown in Fig. 3. The X-axis, Y-axis, and Z-axis in Fig. 4 correspond to the X-axis, Y-axis, and Z-axis in Fig. 3, respectively.

[0042] 3 and 4, the arm 11 and the arm 121 are disposed offset from each other in the vertical direction. In this embodiment, the arm 11 is disposed at a higher position than the arm 121. The first probe 11a is connected to the distal end E1 of the arm body 11b, and the rotation shaft 13a is connected to the proximal end E2 of the arm body 11b. The first probe 11a has an opening OP at its distal end. An elevation actuator of the drive device moves the arm 11 and the rotation shaft 13a integrally in the vertical direction, thereby displacing the arm 11 (and thus the first probe 11a) up and down. For example, when dispensing a reagent into a cuvette 100B set in the colorimetric port P3b, the first probe 11a descends to approach the cuvette 100B, and when dispensing of the reagent is completed, the first probe 11a ascends to move away from the cuvette 100B.

[0043] The chuck 121a is connected to the tip end E3 of the arm body 121b, and the rotation shaft 122a is connected to the base end E4 of the arm body 121b. The base end E4 of the arm body 121b is held by the rotation shaft 122a in a manner that allows it to be displaced in the vertical direction. An elevation actuator of the drive device moves the arm 121 in the vertical direction, thereby displacing the arm 121 (and thus the chuck 121a) up and down. For example, when transferring a cuvette 100A set in the scattering port P3a, the chuck 121a descends to grip the cuvette 100A, and then ascends while still gripping the cuvette 100A to move away from the scattering port P3a. Thereafter, when the arm 121 is rotationally driven by the drive device and the chuck 121a reaches the destination port (more specifically, any port located on the trajectory L1), the chuck 121a descends again to set the cuvette 100A in the port. Once the cuvette 100A is set in the port, the chuck 121a releases (ie, unchuches) the cuvette 100A and rises again.

[0044] Next, the flow of analysis in the analyzer 1000 will be described. The analyzer 1000 simultaneously analyzes multiple samples according to an analysis schedule (FIG. 1). Specifically, the analyzer 1000 performs measurement preparation for one sample (dispensing at the suction port P11 (FIG. 3) or the sample suction port P21 (FIG. 3)) while measuring another sample (optical measurement at the photometric port P3 (FIG. 3)). The analysis schedule is determined based on sample information (e.g., the analysis items for each sample) and the availability of each port so that all reserved samples can be analyzed efficiently. The analysis schedule includes the timing of each dispensing and measurement, information about the sample to be dispensed, information about the reagent to be dispensed, and the number of the photometric port P3 (FIG. 3) where the measurement will be performed. The analysis schedule is stored in the storage device 530 (FIG. 1) and managed for each sample ID (each sample container).

[0045] At the start of the analysis, an ID (cuvette ID) is assigned to the cuvette 100 (Figure 3) used in the analysis. As the analysis progresses, an analysis history (Figure 1) including the progress is saved in the storage device 530 (Figure 1). The analysis history is updated as the analysis progresses. The analysis history includes the movement path of the cuvette 100 (including the current position), the sample and reagent dispensed into the cuvette 100, the photometric port P3 (Figure 3) where the measurement was performed, and the measurement results. The analysis history is managed for each cuvette ID (each cuvette 100). By referring to the analysis history, the user can confirm whether the analysis was performed (or is progressing) according to the analysis schedule.

[0046] 5 is a flowchart showing the flow of analysis by analysis device 1000 according to embodiment 1. The processing shown in FIG. 5 is performed by control device 500, and is realized by CPU 510 executing a program stored in storage device 530.

[0047] 1, 3, and 5, first, the control device 500 supplies a cuvette 100 to the sample dispensing port P1 (step S510). Specifically, the supply mechanism 112 removes the cuvette 100 from the cuvette storage unit 111 and supplies it to the sample dispensing port P1. Based on the output of the port sensor of the sample dispensing port P1, the supply mechanism 112 supplies the next cuvette 100 to the sample dispensing port P1 when the sample dispensing port P1 becomes available.

[0048] Next, the control device 500 dispenses the sample into the cuvette 100 and stirs the contents of the cuvette 100 (step S520). Specifically, the control device 500, while referring to the analysis schedule, controls the movable sample rack 800 to place a predetermined sample (more specifically, a sample set by the analysis schedule) directly below the sample suction port P21. Next, the control device 500 controls the drive device to move the second probe 21a to the sample suction port P21 and cause the second probe 21a to aspirate the sample. Next, the control device 500 controls the drive device to move the second probe 21a to the sample dispensing port P1 and dispense the sample from the second probe 21a into the cuvette 100 (more specifically, the cuvette 100 supplied to the sample dispensing port P1 in step S510). After dispensing, the second probe 21a is washed.

[0049] Next, the control device 500 transfers the cuvette 100 to the photometry port P3 (step S530). Specifically, the control device 500 controls the driving device to move the arm 121, thereby transferring the cuvette 100 from the sample dispensing port P1 to the photometry port P3.

[0050] Next, the control device 500 transfers the cuvette 100 to the agitation port P2 (step S540). Specifically, the control device 500 controls the drive device to move the arm 121, thereby transferring the cuvette 100 from the photometric port P3 to the agitation port P2. However, if the analysis item is a coagulation item, step S540 and step S560, which will be described later, are omitted. In this case, in step S550, which will be described later, the control device 500 dispenses a reagent into the cuvette 100 located at the photometric port P3, without performing agitation after dispensing. The content of the cuvette 100 is mixed by the force of the reagent being dispensed in step S550.

[0051] In step S550, the control device 500 dispenses a reagent into the cuvette 100 containing the sample and stirs the contents of the cuvette 100. Specifically, the control device 500, while referring to the analysis schedule, drives the turntable of the reagent refrigerator 700 to place a predetermined reagent (more specifically, a reagent specified by the analysis schedule) directly below the suction port P11. Next, the control device 500 controls the drive device to move the first probe 11a to the suction port P11 and cause the first probe 11a to aspirate the reagent. Next, the control device 500 controls the drive device to move the first probe 11a to the stirring port P2 and dispense the reagent from the first probe 11a into the cuvette 100. After the dispensing, the contents of the cuvette 100 are stirred by the stirring device 200. Furthermore, after the dispensing, the first probe 11a is washed.

[0052] If the analysis item is a two-reagent colorimetric item, the control device 500 repeats the processes of steps S530 to S550 to dispense the first and second reagents. When dispensing of all reagents is completed, the control device 500 transfers the cuvette 100 to the photometric port P3 (step S560).

[0053] Next, the control device 500 controls the measurement device 300 to perform the measurement described below (step S570).

[0054] For example, if the sample is plasma and the analysis item is coagulation, the clotting time of the sample is measured at scattering port P3a. As the clotting reaction progresses, the intensity of the scattered light increases, and once the clotting reaction is complete, the intensity of the scattered light remains almost constant, allowing the clotting time to be determined from the intensity of the scattered light.

[0055] When the sample is plasma and the analysis item is colorimetric, the concentration and activity value of the sample are measured at the colorimetric port P3b. The control device 500 dispenses a first reagent into the cuvette 100 a predetermined time after dispensing the sample into the cuvette 100, and then dispenses a second reagent (more specifically, a reagent different from the first reagent) into the cuvette 100 a predetermined time after dispensing the first reagent. Dispensing the second reagent into the cuvette 100 initiates a reaction between the sample and the reagent, causing a change in the absorbance of the contents of the cuvette 100. The concentration and activity value of the sample can be determined from this change in absorbance. In such measurements, the first probe 11a is washed after each of dispensing the first and second reagents.

[0056] When the sample is urine, a change in absorbance caused by the reaction between the sample and the reagent is optically measured, for example, at colorimetric port P3b.

[0057] When the above measurement is completed, the control device 500 discards the cuvette 100 (step S580). Specifically, the control device 500 controls the drive device to move the arm 121, thereby transferring the cuvette 100 from the photometric port P3 to the waste port P4, and also releases the zipper of the arm 121 to deposit the cuvette 100 into the waste port P4. Once the cuvette 100 has been deposited into the waste port P4, the cuvette 100 (i.e., the used reaction vessel) is collected in the cuvette waste vessel 400 (FIG. 2).

[0058] After step S580, the control device 500 advances the process to step S510 to start the analysis of the next sample specified by the analysis schedule.

[0059] In this way, the analytical device 1000 dispenses each of the sample and reagent into the cuvette 100 and optically measures the reaction state in the cuvette 100. The measurement results are displayed on the output device 620. In addition to the measurement results, the output device 620 also displays reagent information, sample information, analysis schedules, analysis history, parameters, and the like. When the analytical device 1000 is powered on, the input device 610 accepts user operations not only for the application program 532 but also for the system program 531. Therefore, the user can edit or delete the reagent information, sample information, analysis schedules, analysis history, parameters, and the like, and can also save this data to any recording medium. Furthermore, the user can edit or delete configuration files of the application program 532. Since the user can freely perform operations such as editing, deleting, and saving, there is a risk of personal information being leaked or the application program 532, and ultimately the analytical device 1000, being damaged. Therefore, in the analytical apparatus 1000, when the analytical apparatus 1000 is powered on, a state in which the input device 610 can accept user operations for the system program 531 is restricted, thereby preventing leakage of personal information and breakdown of the analytical apparatus 1000. The restrictions include a first restriction and a second restriction. The first restriction restricts a state in which the input device 610 can accept user operations for the system program 531 on a screen provided by the system program 531. The second restriction restricts a state in which the input device 610 can accept user operations for the system program 531 on a screen provided by the application program 532. The first and second restrictions will be described in detail below.

[0060] Referring to Fig. 6, a process for restricting a state in which input device 610 can accept user operations on system program 531 when analytical device 1000 is powered on will be described. Fig. 6 is a flowchart showing control processing by control device 500 in embodiment 1. The processing shown in Fig. 6 is processing performed by control device 500, and is realized by CPU 510 executing a program stored in storage device 530.

[0061] First, the control device 500 determines whether or not an instruction to power on the analysis device 1000 has been received (step S605). If an instruction to power on the analysis device 1000 has been received (YES in step S605), the control device 500 starts the system program 531 (step S610).

[0062] Next, the control device 500 restricts a state in which a user's operation on the system program 531 can be accepted via the input device 610 on the screen provided by the system program 531 (first restriction) (step S615). Specifically, after the system program 531 is started, the control device 500 restricts a display suggesting to the user that an operation on the system program 531 can be accepted from being displayed on the screen provided by the system program 531. When the system program 531 is started, the screen provided by the system program 531 is displayed on the output device 620. Therefore, the control device 500 restricts a display suggesting to the user that an operation on the system program 531 (for example, an operation button for removing an external storage device, or, if the system program 531 is Windows (registered trademark), a Windows shortcut key, etc.) can be accepted on the screen provided by the system program 531.

[0063] After the power of the analytical device 1000 is turned on, during the period from when the system program 531 is started until the analytical device 1000 is turned off, if a display (e.g., a Windows shortcut key) indicating to the user that operations for the system program 531 are available is displayed on a screen provided by the system program 531, the user can edit or delete reagent information, sample information, analysis schedules, analysis history, parameters, etc., and can also save this data to any recording medium. Furthermore, the user can edit or delete configuration files of the application program 532. Since the user can freely perform operations such as editing, deleting, and saving, there is a risk of personal information being leaked or the application program 532 and, ultimately, the analytical device 1000 being damaged. However, in the analytical device 1000, after the system program 531 is started, a display indicating to the user that operations for the system program 531 are available is not displayed on a screen provided by the system program 531, thereby preventing personal information from being leaked or the analytical device 1000 from being damaged.

[0064] Next, control device 500 starts application program 532 (step S620). In analytical device 1000, due to the first restriction, even after system program 531 has started, a display suggesting to the user that operations for system program 531 can be accepted is not displayed on the screen provided by system program 531. Therefore, in analytical device 1000, after analytical device 1000 is powered on, application program 532 starts without a display suggesting to the user that operations for system program 531 can be accepted being displayed on the screen provided by system program 531. Therefore, after analytical device 1000 is powered on, a state in which input device 610 can accept operations for system program 531 is limited until application program 532 starts.

[0065] Furthermore, in the analysis device 1000, due to the first restriction, even while the application program 532 is running, a display suggesting to the user that operations on the system program 531 can be accepted is not displayed on the screen provided by the system program 531. Therefore, even while the application program 532 is running, the state in which the input device 610 can accept operations on the system program 531 from the user is limited.

[0066] Next, the control device 500 restricts a state in which a user's operation for the system program 531 can be accepted by the input device 610 on the screen provided by the application program 532 (second restriction) (step S625). Specifically, after the application program 532 is started, the control device 500 restricts a display suggesting to the user that an operation for the system program 531 can be accepted (for example, an operation button for opening a screen provided by the system program 531) from being displayed on the screen provided by the application program 532.

[0067] Screens provided by the system program 531 include, for example, a screen for specifying a storage location for backup data (hereinafter also referred to as a "storage location specification screen"). The operation of specifying a storage location for backup data is one of the operations performed by the user on the system program 531. Here, with reference to FIGS. 7 to 10, a display restriction on the operation button for opening the storage location specification screen will be described as an example of the second restriction.

[0068] One of the various functions provided by the application program 532 is a function to back up information related to automatic analysis (for example, reagent information, sample information, analysis schedule, analysis history, setting information (parameters) required for analysis, etc.). The backup function includes an automatic backup function that automatically starts a backup when the power of the analysis device 1000 is turned on for the first time on a new day, and a manual backup function that starts a backup when the user instructs a backup. Here, the user can enable / disable the automatic backup function on an environment setting screen provided by the application program 532, and can enable / disable the manual backup function on a recovery setting screen provided by the application program 532.

[0069] Fig. 7 is a diagram showing an environment setting screen 650 of the analysis apparatus 1000 according to the first embodiment. Fig. 8 is a diagram showing a recovery setting screen 660 of the analysis apparatus 1000 according to the first embodiment. Fig. 9 is a diagram showing an environment setting screen 650A of an analysis apparatus to be compared with the analysis apparatus 1000 according to the first embodiment. Fig. 10 is a diagram showing a recovery setting screen 660A of an analysis apparatus to be compared with the analysis apparatus 1000 according to the first embodiment.

[0070] 7 and 8, the environment setting screen 650 and the recovery setting screen 660 are provided by the application program 532 and displayed on the output device 620 (FIG. 1). The environment setting screen 650 displays an operation button 651 for enabling / disabling the automatic backup function. The user can enable the automatic backup function by operating the operation button 651 with the input device 610 (FIG. 1) (for example, by touching the touch panel or clicking with a mouse). The recovery setting screen 660 displays an operation button 661 for enabling / disabling the manual backup function. The user can enable the manual backup function by operating the operation button 661 with the input device 610 (for example, by touching the touch panel or clicking with a mouse). On the other hand, the environment setting screen 650 and the recovery setting screen 660 do not display an operation button for opening a save location specification screen, and the user cannot arbitrarily specify a save location for backup data. In the analysis device 1000, the save location for backup data is predefined in a configuration file of the application program 532.

[0071] In contrast, as shown in FIG. 9, an environment setting screen 650A displayed on an output device of an analytical device to be compared with the analytical device 1000 displays an operation button 651A for enabling / disabling the automatic backup function, as well as an operation button 652A for opening a save location specification screen. When the user operates operation button 652A (for example, by touching a touch panel or clicking with a mouse), a screen provided by the system program opens, allowing the user to specify a save location for the backup data. Also, as shown in FIG. 10, a recovery setting screen 660A displayed on an output device of an analytical device to be compared with the analytical device 1000 displays an operation button 661A for enabling / disabling the manual backup function, as well as an operation button 662A for opening a save location specification screen. When the user operates operation button 662A (for example, by touching a touch panel or clicking with a mouse), a screen provided by the system program opens, allowing the user to specify a save location for the backup data.

[0072] If an operation button for opening a storage location specification screen is displayed on the environment setting screen 650 and the recovery setting screen 660, there is a risk that the user will save the backup data in a storage location other than the predefined storage location. Backup data is information related to automated analysis, such as reagent information, sample information, analysis schedule, and analysis history, and includes personal information. Therefore, saving backup data in a storage location other than the predefined storage location can lead to the leakage of personal information. However, in the analytical device 1000, the operation button for opening the storage location specification screen is not displayed on the screen provided by the application program 532, thereby preventing the leakage of personal information.

[0073] 6 again, next, control device 500 determines whether or not connection of an external storage device to analysis device 1000 has been detected (step S630). An external storage device is, for example, a USB (Universal Serial Bus) memory. If connection of an external storage device to analysis device 1000 has been detected (YES in step S630), control device 500 proceeds to step S635. On the other hand, if connection of an external storage device to analysis device 1000 has not been detected (NO in step S630), control device 500 proceeds to step S640.

[0074] In step S635, the control device 500 displays an operation button 671 for safely removing the external storage device from the analytical device 1000 on the screen provided by the application program 532, and then proceeds to step S640.

[0075] Here, referring to FIG. 11, a display provided by the application program 532 when an external storage device is connected to the analysis device 1000 will be described, taking as an example a case where the external storage device is a USB. FIG. 11 is a diagram showing a display when a USB is connected to the analysis device 1000 in the first embodiment. A screen 670 is provided by the application program 532 and is displayed on the output device 620 (FIG. 1). When connection of a USB to the analysis device 1000 is detected, an operation button 671 is displayed on the screen 670. The operation button 671 is a button for instructing the execution of a process for safely removing the USB from the analysis device 1000. The user can safely remove the USB from the analysis device 1000 by operating the operation button 671 with the input device 610 (FIG. 1) (for example, by touching a touch panel or clicking with a mouse).

[0076] The process for safely removing the USB from the analysis device 1000 is a process performed by the system program 531, and the operation for instructing the execution of the process for safely removing the USB from the analysis device 1000 is one of the operations by the user on the system program 531. In the analysis device 1000, due to the first restriction, an operation button for safely removing the USB is not displayed on the screen provided by the system program 531. Therefore, in the analysis device 1000, when a USB is connected to the analysis device 1000, an operation button 671 is displayed on the screen provided by the application program 532, so that the USB can be safely removed from the analysis device 1000.

[0077] Note that USB is just one example, and displaying the operation button 671 for safely removing the external storage device on the screen provided by the application program 532 also applies to external storage devices other than USB.

[0078] 6 again, in step S640, control device 500 determines whether it has received an instruction to power off analysis device 1000. An operation button for powering off analysis device 1000 is displayed on the start / end screen of application program 532, and the user can power off analysis device 1000 by operating this operation button with input device 610.

[0079] 12 and 13, a display restriction on the start / end screen of the application program 532 will be described as another example of the second restriction. FIG. 12 is a diagram showing a start / end screen 680 of the application program 532 of the analysis device 1000 according to the first embodiment. FIG. 13 is a diagram showing a start / end screen 680A of an application program of an analysis device compared to the analysis device 1000 according to the first embodiment. The start / end screen 680 is provided by the application program 532 and is displayed on the output device 620 (FIG. 1). The start / end screen 680 displays an operation button 681 for powering off the analysis device 1000. When the user operates the operation button 681 with the input device 610 (FIG. 1) (for example, by touching the touch panel or clicking with a mouse), the application program 532 and the system program 531 are terminated, and the analysis device 1000 is powered off. On the other hand, the start / end screen 680 does not display any operation buttons for terminating the application program 532 and displaying the screen provided by the system program 531, and the user cannot operate the system program 531 after terminating the application program 532.

[0080] In contrast, application program start / end screen 680A of an analyzer compared to analyzer 1000 in embodiment 1 displays operation button 681A for powering off the analyzer, as well as operation button 682A for terminating the application program and displaying a screen provided by the system program. The user can terminate the application program and then operate the system program by operating operation button 682A with input device 610 (for example, by touching the touch panel or clicking with a mouse).

[0081] If the system program 531 can be operated after the application program 532 has been terminated, the user may perform operations on the system program 531 (for example, operations to save backup data to another storage device, operations to edit and / or delete configuration files of the application program 532, etc.). Saving backup data to another storage device may result in the leakage of personal information because the backup data includes personal information such as reagent information, sample information, analysis schedules, and analysis histories. Furthermore, operations to edit and / or delete configuration files of the application program 532 may cause a malfunction of the application program 532 and, ultimately, the analytical device 1000. However, the analytical device 1000 does not display, on the screen provided by the application program 532, a display that suggests to the user that operations on the system program 531 can be accepted via the input device 610 after the application program 532 has been terminated (for example, an operation button for terminating the application program 532 and displaying a screen provided by the system program 531). As a result, in the analytical device 1000, operations on the system program 531 after the application program 532 has been terminated are restricted, thereby preventing personal information from being leaked and the analytical device 1000 from breaking down.

[0082] Referring again to FIG. 6, when an instruction to power off analytical device 1000 is received (YES in step S640), control device 500 terminates application program 532 (step S645).

[0083] Next, the control device 500 terminates the system program 531 (step S650). In the analytical device 1000, due to the first restriction, even after the application program 532 has terminated, no indication is displayed on the screen provided by the system program 531 to suggest to the user that operations on the system program 531 can be accepted. Therefore, in the analytical device 1000, after the application program 532 has terminated, no indication is displayed on the screen provided by the system program 531 to suggest to the user that operations on the system program 531 can be accepted, and the termination process for the system program 531 is started. This restricts the state in which the input device 610 can accept operations on the system program 531 from the user after the application program 532 has terminated until the system program 531 has terminated.

[0084] After step S650, control device 500 ends the series of processes shown in FIG.

[0085] 6, the analytical device 1000 can limit the state in which the input device 610 can accept user operations on the system program 531 from the time the analytical device 1000 is powered on until the time the analytical device 1000 is powered off. As a result, it is possible to prevent leakage of personal information and breakdown of the analytical device 1000. Furthermore, the analytical device 1000 can be controlled to a state in which it can exceptionally accept an operation for safely removing an external storage device from the analytical device 1000, so that the external storage device can be safely removed from the analytical device 1000.

[0086] In the above, restricting the display of Windows shortcut keys was given as an example of the first restriction, but if system program 531 is a system program other than Windows (for example, MacOS, etc.), it is also possible to restrict the display of Windows shortcut keys provided in the system program other than Windows.

[0087] Furthermore, in the above description, the first restriction is set to restrict the display on the screen provided by the system program 531 of a message indicating to the user that operations on the system program 531 can be accepted, but it may also be set to restrict the acceptance of the operation of pressing the Windows button on the keyboard when it is pressed.

[0088] The start / end screen 680 (FIG. 12) also displays fields for inputting a user ID, user name, and password, as well as an operation button 681 (FIG. 12) for powering off the analytical device 1000. When the input user ID, user name, and password are authenticated, the analytical device 1000 is controlled to a state in which the user has logged in with that user ID, and the user can use the various functions provided by the application program 532.

[0089] [Embodiment 2] In the first embodiment, the first and second restrictions were imposed on the analytical device 1000 regardless of whether the logged-in mode was user mode or service mode. In contrast, in the analytical device of the second embodiment, the first and second restrictions are imposed when the logged-in mode is user mode, and neither the first nor the second restrictions are imposed when the logged-in mode is service mode. Note that although the control processing by the control device differs between the first and second embodiments, the configurations of the analytical devices are similar, and therefore, similar configurations are denoted by the same reference numerals and their description will not be repeated. In the following, only the differences from the first embodiment, i.e., the control processing by the control device, will be described.

[0090] Fig. 14 is a flowchart showing control processing by control device 500 in embodiment 2. The processing shown in Fig. 14 is performed by control device 500, and is realized by CPU 510 executing a program stored in storage device 530. Note that, hereinafter, processing similar to that in embodiment 1 will not be described in detail.

[0091] First, the control device 500 determines whether or not an instruction to power on the analysis device 1000 has been received (step S1405). If an instruction to power on the analysis device 1000 has been received (YES in step S1405), the control device 500 starts the system program 531 (step S1410).

[0092] Next, the control device 500 restricts the state in which the input device 610 can accept user operations for the system program 531 on the screen provided by the system program 531 (step S1415).

[0093] Next, the control device 500 starts the application program 532 (step S1420).

[0094] Next, the control device 500 determines whether a login operation in the service mode has been accepted (step S1425). The service mode is a mode that is mainly used during maintenance of the analytical device 1000, and the user mode is a mode that is mainly used during analysis. The control device 500 determines whether a login operation in the service mode has been accepted based on the user ID entered on the start / end screen 680. If it is determined that a login operation in the service mode has been accepted (YES in step S1425), the control device 500 releases the first restriction (step S1445) and proceeds to step S1450. On the other hand, if it is determined that a login operation in the service mode has not been accepted (i.e., a login operation in the user mode has been accepted) (NO in step S1425), the control device 500 proceeds to step S1430.

[0095] In step S1430, the control device 500 restricts the state in which a user's operation on the system program 531 via the input device 610 can be accepted on the screen provided by the application program 532.

[0096] Next, control device 500 determines whether or not connection of an external storage device to analysis device 1000 has been detected (step S1435). If connection of an external storage device to analysis device 1000 has been detected (YES in step S1435), control device 500 proceeds to step S1440. On the other hand, if connection of an external storage device to analysis device 1000 has not been detected (NO in step S1435), control device 500 proceeds to step S1450.

[0097] In step S1440, the control device 500 displays an operation button 671 for safely removing the external storage device from the analytical device 1000 on a screen provided by the application program 532, and then proceeds to step S1450.

[0098] In step S1450, control device 500 determines whether or not it has received an instruction to power off analysis device 1000. If it has received an instruction to power off analysis device 1000 (YES in step S1450), control device 500 terminates application program 532 (step S1455).

[0099] Next, the control device 500 ends the system program 531 (step S1460), and ends the series of processes shown in FIG.

[0100] 6 and 14, the control process in the second embodiment differs from the control process in the first embodiment in the following two points. First, after application program 532 is started (step S1420), it is determined whether a login operation in service mode has been accepted (step S1425), and if it is determined that a login operation in service mode has been accepted (YES in step S1425), the first restriction is lifted (step S1445). Second, if it is determined that a login operation in service mode has been accepted (YES in step S1425), the second restriction is not imposed.

[0101] 14, in the analysis device 1000 according to the second embodiment, the first and second restrictions are imposed when logged in as a user, but neither the first nor the second restrictions are imposed when logged in as a service. When logged in as a service and performing maintenance, for example, there are situations where an operation on the system program 531 must be performed. According to the second embodiment, when logged in as a service, the state in which the input device 610 can accept user operations on the system program 531 is not restricted, and maintenance can be performed efficiently. Furthermore, when logged in as a user, the state in which the input device 610 can accept user operations on the system program 531 is restricted, thereby preventing leakage of personal information and breakdown of the analysis device 1000.

[0102] [Variations] The exemplary embodiment described above may be applied not only to the analyzer 1000 that performs biochemical analysis of a sample by reacting the sample with a reagent, but also to other sample testing equipment, such as (general-purpose) clinical chemistry analyzers, electrolyte analyzers, blood gas analyzers, immunoserological testing equipment, blood testing equipment, blood cell counters, blood coagulation analyzers, and urinalysis equipment.

[0103] [Aspect] It will be appreciated by those skilled in the art that the exemplary embodiments described above are examples of the following aspects.

[0104] (Item 1) An automatic analyzer according to one embodiment includes a reception unit that receives user operations, a memory unit that stores a system program for managing the system of the automatic analyzer and an application program that is executed under the control of the system program and performs automatic analysis, and a control unit that executes the system program and the application program stored in the memory unit. The control unit limits the state in which the reception unit can receive user operations for the system program while the application program is running.

[0105] According to the automatic analyzer described in paragraph 1, the state in which the accepting unit can accept user operations for the system program while an application program is running is limited, thereby preventing leakage of personal information and device failure.

[0106] (2) In the automatic analyzer described in paragraph 1, after the application program has ended, the control unit starts the termination process of the system program without setting a period during which the reception unit can accept user operations on the system program.

[0107] According to the automatic analyzer described in paragraph 2, after an application program has finished, the state in which the reception unit can receive user operations for the system program is limited, thereby preventing leakage of personal information and device failure.

[0108] (Item 3) In the automatic analyzer described in item 1 or 2, the control unit starts the application program after the automatic analyzer is turned on, without setting a period during which the reception unit can accept user operations on the system program.

[0109] According to the automatic analyzer described in paragraph 3, after the power of the automatic analyzer is turned on, the state in which the reception unit can receive user operations for the system program is limited, thereby preventing the leakage of personal information and device failure.

[0110] (4) In the automatic analyzer described in any one of paragraphs 1 to 3, the control unit restricts a user's operation to specify a backup destination for information related to automatic analysis while an application program is running.

[0111] According to the automatic analyzer described in paragraph 4, backup data of information related to automatic analysis can be restricted from being stored in a storage location other than a predetermined storage location, thereby preventing leakage of personal information.

[0112] (Item 5) The automated analyzer according to any one of Items 1 to 4 further includes a display unit that displays a screen provided by the application program. The control unit restricts the display unit from displaying a message that suggests to the user that operations for the system program are available while the application program is running.

[0113] According to the automated analyzer described in paragraph 5, while an application program is running, no indication is displayed on the display unit to indicate to the user that operations on the system program are available, thereby restricting user operations on the system program, thereby preventing leakage of personal information and device malfunctions.

[0114] (Item 6) In the automatic analyzer described in item 5, when an external storage device is connected to the automatic analyzer, the control unit displays an operation button for removing the external storage device on a screen provided by the application program.

[0115] According to the automatic analyzer described in paragraph 6, an operation button for removing the external storage device is displayed on a screen provided by the application program, thereby enabling the external storage device to be safely removed.

[0116] (Item 7) In the automatic analyzer described in Item 5 or 6, after the application program has terminated, the control unit starts the termination process of the system program without displaying on the display unit a message informing the user that operations on the system program are available.

[0117] According to the automatic analyzer described in paragraph 7, after an application program has finished, no indication is displayed on the display unit to indicate to the user that operations on the system program are available, thereby restricting user operations on the system program, thereby preventing leakage of personal information and device malfunctions.

[0120] (Item 9) In the automatic analyzer described in any one of Items 5 to 8, the control unit limits the display on the display unit of a screen related to a user's operation to specify a backup destination for information related to the automatic analysis while the application program is running.

[0121] According to the automatic analyzer described in paragraph 9, backup data of information related to automatic analysis is restricted from being stored in a storage location other than the predetermined storage location, thereby preventing leakage of personal information.

[0122] (Item 10) In the automatic analyzer described in any one of Items 1 to 9, the control unit switches between a first mode, which limits the state in which the reception unit can accept user operations for the system program while the application program is running, and a second mode, which enables the reception unit to accept user operations for the system program while the application program is running, based on operations accepted by the reception unit.

[0123] According to the automatic analyzer described in paragraph 10, when logged in in service mode, the state in which the reception unit can accept user operations for the system program is not limited, allowing for efficient maintenance. Also, when logged in in user mode, the state in which the reception unit can accept user operations for the system program is limited, preventing leakage of personal information and device failure.

[0124] (Item 11) The automatic analyzer according to any one of items 1 to 10 is an apparatus that performs biochemical analysis of a sample by causing the sample to react with a reagent.

[0125] According to the automatic analyzer described in paragraph 11, in an apparatus that performs biochemical analysis of a sample by causing the sample to react with a reagent, leakage of personal information and breakdown of the apparatus can be prevented.
