Technical Field

The present disclosure relates to an automatic analysis device.

Background

One of the following blood coagulation assays is known: a reagent is injected into a reaction vessel (hereinafter, referred to as a "cuvette") into which a sample such as blood components or urine is dispensed, and scattered light or transmitted light when light is irradiated is measured, whereby the coagulation function and fibrinolysis function of the sample are analyzed.

As methods for such blood coagulation analysis, a method of measuring a coagulation time and a colorimetric method are known. The former is one of the following methods: the cuvette into which the specimen and the reagent are injected is irradiated with light, and the coagulation time of each item is calculated from the process of the change in the intensity of the scattered light. The latter is one of the following methods: the cuvette into which the sample and the reagent are injected is irradiated with light of a specific wavelength to measure absorbance, and the concentration or activity value of each item is calculated from the absorbance after a predetermined time or the amount of change in absorbance within a predetermined time. In addition, the colorimetric method is sometimes called an absorbance measurement method.

The cuvette supply 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 a sample into the cuvette. The cuvette transport device 120 transports cuvettes to which samples are dispensed. The reagent dispensing device 10 dispenses a reagent into a cuvette into which a sample is dispensed. The stirring device 200 stirs the contents of the comparison cuvette under prescribed conditions (e.g., stirring speed and stirring time). The measuring apparatus 300 performs a predetermined measurement on the contents of the cuvette. In the present embodiment, the measurement device 300 includes 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 a change in the amount of light detected by the photodetector.

Fig. 2 is a diagram showing a configuration in which the conveyance and disposal of cuvettes and the stirring and measurement of the content of cuvettes are performed in the analysis apparatus 1000 according to embodiment 1.

The analyzer 1000 includes a sample dispensing port P1. The cuvette supplying apparatus 110 includes a cuvette holding portion 111 and a supplying mechanism 112. The cuvette holding portion 111 can hold a plurality of cuvettes (for example, up to 1000 cuvettes). The supply mechanism 112 supplies the cuvette accommodated in the cuvette accommodating portion 111 to the sample dispensing port P1. Details of the cuvette holding section 111 and the supply mechanism 112 will be described with reference to FIG. 3.

The sample dispensing port P1 is disposed at a position where the sample dispensing device 20 (fig. 1) can dispense a sample to the cuvette. When the cuvette is placed at the sample dispensing port P1, a sample is dispensed to the cuvette by the sample dispensing device 20.

The cuvette conveying apparatus 120 includes an arm 121 with a gripper (hereinafter, simply referred to as "arm 121") and a driving apparatus 122. The arm 121 has a gripper configured to grip the cuvette. The arm 121 is configured to detachably hold the cuvette by a jig. The driving device 122 moves the arm 121 to change the position of the jig. Details regarding the arm 121 and the drive device 122 will also be explained in fig. 3.

The analyzer 1000 further includes a plurality of ports through which the cuvette can be conveyed by the cuvette conveying device 120, and specifically, further includes an agitation port P2, a photometric port P3, and a disposal port P4. The photometric port P3 includes a plurality of scattering ports P3a and a plurality of colorimetric ports P3 b. Port sensors for detecting the presence or absence of a cuvette are provided at the respective ports of the sample dispensing port P1, the stirring port P2, the photometric port P3, and the disposal port P4.

The stirring port P2 is disposed at the stirring position of the stirring device 200. When the cuvette is placed in the stirring port P2, the stirring apparatus 200 stirs the contents of the cuvette under prescribed conditions (e.g., stirring speed and stirring time).

The scattering port P3a and the colorimetric port P3b are disposed at the measurement positions of the measurement device 300, respectively. Hereinafter, the scattering port P3a and the colorimetric port P3b are respectively referred to as "photometric port P3" unless otherwise stated.

The measuring apparatus 300 is configured to measure the contents of the cuvette by a predetermined measurement. In the present embodiment, the measurement device 300 includes a light source and a photodetector, irradiates the content of the cuvette placed at any one of the photometric ports P3 with light from the light source, and measures the reaction state in the cuvette based on a change in the amount of light detected by the photodetector. The measurement device 300 includes a light source and a light detector for the scattering port P3a and a light source and a light detector for the colorimetric port P3 b. As the light source and the light detector for the scattering port P3a, a light emitting diode and a photodiode can be used, respectively. The 90 ° scattered light (i.e., scattered light in a direction orthogonal to the irradiation direction of the light) is detected by the photodetector of the scattering port P3 a. As the light source and the photodetector for the colorimetric port P3b, a halogen lamp and a photodiode can be used, respectively. The transmitted light amount is detected by the photodetector of the colorimetric port P3 b.

The waste port P4 is used to recover used cuvettes. The disposal port P4 is connected to the cuvette disposal container 400 via a pipe. When a cuvette is dropped into the discard port P4, the cuvette is guided to the cuvette discard container 400.

Fig. 3 is a plan view of an analysis stage provided in the analysis device 1000 according to embodiment 1. Three axes (X, Y, and Z axes) orthogonal to each other are shown in fig. 3. Among the X, Y, and Z axes, the X axis represents the width direction of the analyzer, the Y axis represents the depth direction of the analyzer, and the Z axis represents the vertical direction (i.e., the up-down direction). The direction indicated by the arrow of the Z axis corresponds to "up", and the opposite direction corresponds to "down (i.e., the direction of gravity)".

Referring to fig. 2 and 3, the cuvette storage portion 111 stores a plurality of cuvettes 100. The user can replenish the cuvette 100 in the cuvette holding portion 111 from the input port of the cuvette holding portion 111. The material of the cuvette 100 is arbitrary as long as the cuvette 100 can transmit light therethrough, and for example, a material made of transparent acrylic acid can be used.

The supply mechanism 112 takes out the cuvettes 100 one by one from the cuvette holding portion 111 and supplies the cuvette to the sample dispensing port P1. The conveyance method of the cuvette 100 by the supply mechanism 112 is arbitrary, and may be any of, for example, a slide table method (self-weight method), a conveyor belt method, a roller method, and a slide method. The supply mechanism 112 receives the detection result of the port sensor of the sample dispensing port P1, and if the sample dispensing port P1 is empty, supplies the next cuvette 100 to the sample dispensing port P1. However, the supply mechanism 112 is not limited to this case, and the cuvette 100 may be supplied to the sample dispensing port P1 in accordance with an instruction from the control device 500 (fig. 1).

The arm 21 is a device (sample dispensing apparatus 20 (fig. 1)) for dispensing the sample suctioned from the sample suction port P21 into the cuvette 100 placed in the sample dispensing port P1. The arm 21 includes a second probe 21a and an arm main body 21 b. The second probe 21a provided at the distal end of the arm main body 21b moves on the XY plane so as to draw an arc-shaped trajectory L2 by the arm main body 21b rotating about the rotation shaft 23 a.

By the rotation of the arm main body 21b, the second probe 21a moves to each of the sample dispensing port P1, the sample suction port P21, the S port P22, and the wash port P23 provided on the rail L2. S-ports P22 include detergent ports P22a, P22b, buffer ports P22c, P22d, P22e and plasma-deficient ports P22f, P22g, P22h, P22 i.

A movable sample holder 800 (fig. 1) is provided below the sample suction port P21. A plurality of sample containers each containing a sample such as blood components or urine are placed on the sample holder 800. Before dispensing a sample into the cuvette 100 placed in the sample dispensing port P1, the sample rack 800 operates such that a sample container to be dispensed is disposed directly below the sample suction port P21. The CTS mechanism 24 is disposed in the vicinity of the sample suction port P21. In the case where a cap is attached to the sample container to be dispensed, the CTS mechanism 24 drills the cap with a drill.

The arm 11 is a device (reagent dispensing apparatus 10 (fig. 1)) for dispensing a reagent suctioned from the suction ports P11 and P12 to the cuvette 100 placed as a target at the photometric port P3. The arm 11 includes a first probe 11a and an arm body 11 b. The first probe 11a provided at the distal end of the arm main body 11b moves on the XY plane so as to draw an arc-shaped trajectory L1 by rotating the arm main body 11b about the rotation shaft 13 a.

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 and P12. The reagent tray 710 is disposed inside the reagent cooling chamber 700. The plurality of reagent containers a hold different reagents from each other, and the plurality of detergent containers hold different detergents from each other. The reagent tray 710 is a disk-shaped turntable, and a desired reagent container a (or detergent container) is disposed directly below the suction ports P11 and P12 by driving the turntable. The first probe 11a is used for sucking a reagent (or a cleaning solution) in a reagent container a (or a detergent container) disposed directly below the suction ports P11 and P12.

By the rotation of the arm body 11b, the first probe 11a moves to each of the stirring port P2, the scattering ports P3a, the colorimetric ports P3b, the suction ports P11, P12, and the wash port P13 provided on the rail L1. In order to avoid contamination between reagents, the first probe 11a may be composed of two probes. The reagent tray 710 may have an outer peripheral tray and an inner peripheral tray. The two probes suck the reagent (or cleaning solution) on the outer peripheral tray and the reagent (or cleaning solution) on the inner peripheral tray from the suction ports P11, P12. Cleaning port P13 is a port for collecting used cleaning liquid, and includes a water accumulating portion for accumulating water ejected from first probe 11a and cleaning the outer surface of the tip of the probe, and a disposal portion for disposing of the liquid, although not particularly shown.

The arm 121 includes a clamp 121a and an arm body 121 b. The gripper 121a is configured to be able to grip the cuvette 100. The mode of holding the cuvette 100 by the clamp 121a is arbitrary, and the clamp 121a may be a mechanical clamp, a magnetic clamp, or a vacuum clamp. The arm main body 121b rotates about the rotation shaft 122a, and the jig 121a provided at the distal end of the arm main body 121b can move on the XY plane so as to draw an arc-shaped trajectory L1.

As described above, the rotation centers of the arm 11 and the arm 121 are the same. 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 disposal port P4, suction ports P11, P12, and a wash port P13 are provided on the rail L1. The arm 121 can move the gripper 121a to the sample dispensing port P1, the agitation port P2, each photometric port P3, and the disposal port P4, and the arm 11 can move the first probe 11a to the suction ports P11, P12, the wash port P13, the agitation port P2, and each photometric port P3.

Fig. 4 is a diagram for explaining the configuration of the arm 11 and the arm 121 shown in fig. 3. The X, Y, and Z axes in fig. 4 correspond to the X, Y, and Z axes in fig. 3, respectively.

Referring to fig. 3 and 4, the arm 11 and the arm 121 are arranged to be offset in the vertical direction. In the present embodiment, the arm 11 is disposed at a position higher than the arm 121. The first probe 11a is connected to a distal end portion E1 of the arm main body 11b, and the rotary shaft 13a is connected to a base end portion E2 of the arm main body 11 b. First probe 11a has opening OP at its tip. The lift actuator of the driving device moves the arm 11 and the rotary shaft 13a in the vertical direction integrally, whereby the arm 11 (and thus the first probe 11a) is displaced vertically. For example, when dispensing a reagent into the cuvette 100B placed at the cuvette port P3B, the first probe 11a moves down to approach the cuvette 100B, and when dispensing of the reagent is completed, the first probe 11a moves up to separate from the cuvette 100B.

The holder 121a is connected to the distal end portion E3 of the arm body 121b, and the rotary shaft 122a is connected to the base end portion E4 of the arm body 121 b. The base end E4 of the arm body 121b is held on the rotary shaft 122a so as to be displaceable in the vertical direction. The arm 121 (and thus the gripper 121a) is displaced up and down by moving the arm 121 in the up and down direction by a lifting actuator of the driving device. For example, the gripper 121a descends to grip the cuvette 100A when transporting the cuvette 100A placed at the scattering port P3a, and ascends to leave the scattering port P3a while gripping the cuvette 100A. Thereafter, the arm 121 is rotationally driven by the driving device, and after the gripper 121a reaches the port of the transport destination (more specifically, one of the ports located on the rail L1), the gripper 121a is lowered again to place the cuvette 100A at the port. After the cuvette 100A is placed at the port, the gripper 121a releases the cuvette 100A (i.e., the gripper releases) and rises again.

Next, the flow of analysis by the analyzer 1000 will be described. The analysis device 1000 simultaneously analyzes a plurality of samples according to the analysis schedule (fig. 1). Specifically, the analyzer 1000 performs measurement of another sample (optical measurement at the photometric port P3 (fig. 3)) while performing measurement preparation of a certain sample (dispensing at the aspiration port P11 (fig. 3) or the sample aspiration port P21 (fig. 3)). The analysis schedule is decided based on the sample information (for example, analysis items of each sample) and the idle state of each port, so that the analysis of all the reserved samples is efficiently performed. The analysis schedule includes the dispensing timing and the measurement timing, information on a sample to be dispensed, information on a reagent to be dispensed, and the number of a photometric port P3 (fig. 3) for measurement. The analysis schedule is stored in the storage device 530 (fig. 1), and the analysis schedule is managed for each sample ID (for each sample container).

At the start of analysis, an ID (cell ID) is assigned to the cell 100 (fig. 3) used for analysis. When the analysis is performed, the analysis history (fig. 1) including the halfway passage is saved to the storage device 530 fig. 1). The analysis chronicle is updated in turn as the analysis progresses. The analysis history includes the movement path (including the current position) of the cuvette 100, the sample and reagent dispensed into the cuvette 100, the photometric port P3 (fig. 3) where the measurement is performed, and the measurement result. The analysis history is managed for each cuvette ID (each cuvette 100). The user can confirm whether or not the analysis is performed (or whether or not there is progress) on the analysis schedule by referring to the analysis history.

Fig. 5 is a flowchart showing an analysis flow of the analysis device 1000 according to embodiment 1. The process shown in fig. 5 is a process performed by control device 500, and CPU510 realizes the process shown in fig. 5 by executing a program stored in storage device 530.

Referring to fig. 1, 3, and 5, first, the control device 500 supplies the cuvette 100 to the sample dispensing port P1 (step S510). Specifically, the supply mechanism 112 takes out the cuvette 100 from the cuvette holding portion 111 and supplies the cuvette to the sample dispensing port P1. The supply mechanism 112 supplies the next cuvette 100 to the sample dispensing port P1 if it is determined based on the output of the port sensor of the sample dispensing port P1 that the sample dispensing port P1 is empty.

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 controls the movable specimen holder 800 while referring to the analysis schedule, and thereby arranges a predetermined specimen (more specifically, a specimen set in the analysis schedule) directly below the specimen suction port P21. Next, the control device 500 controls the driving device so that the second probe 21a moves to the sample suction port P21 and the second probe 21a sucks the sample. Next, the control device 500 controls the drive device to move the second probe 21a to the sample dispensing port P1, and to 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 cleaned.

Next, the control device 500 conveys the cuvette 100 to the photometry port P3 (step S530). Specifically, the control device 500 controls the drive device to move the arm 121, thereby transferring the cuvette 100 from the sample dispensing port P1 to the photometric port P3.

Subsequently, the control device 500 conveys the cuvette 100 to the stirring port P2 (step S540). Specifically, the control device 500 controls the drive device to move the arm 121, thereby transporting the cuvette 100 from the photometric port P3 to the stirring port P2. However, when the analysis item is a freeze item, step S540 and step S560 described later are omitted. In this case, in step S550 to be described later, the control device 500 dispenses a reagent into the cuvette 100 positioned at the photometric port P3, and does not stir the dispensed reagent. The contents of the cuvette 100 are mixed by the momentum of the reagent ejection in step S550.

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 drives the turntable of the reagent cooling box 700 while referring to the analysis schedule, and thereby arranges a predetermined reagent (more specifically, a reagent specified by the analysis schedule) directly below the suction port P11. Next, control device 500 controls the driving device so that first probe 11a moves to suction port P11 and first probe 11a sucks the reagent. Subsequently, the controller 500 controls the driving device to move the first probe 11a to the stirring port P2, and to dispense the reagent from the first probe 11a into the cuvette 100. After dispensing, the contents of the cuvette 100 are stirred by the stirring apparatus 200. After dispensing, first probe 11a is cleaned.

When the analysis item is a colorimetric item of two reagents, the control device 500 repeats the processing of steps S530 to S550 and dispenses the first reagent and the second reagent. After dispensing of all reagents is completed, the control device 500 conveys the cuvette 100 to the photometric port P3 (step S560).

Next, the controller 500 controls the measuring device 300 to perform the measurement described below (step S570).

For example, when the sample is plasma and the analysis item is a coagulation item, the coagulation time of the sample is measured at the scattering port P3 a. Since the intensity of scattered light increases as the coagulation progresses and the intensity of scattered light hardly changes after the coagulation reaction is completed, the coagulation time can be determined from the intensity of scattered light.

In the case where the sample is plasma and the analysis item is a colorimetric item, the concentration and activity value of the sample are measured at the colorimetric port P3 b. The control device 500 dispenses the first reagent into the cuvette 100 after a predetermined time has elapsed from the dispensing of the sample into the cuvette 100, and dispenses the second reagent (more specifically, a reagent different from the first reagent) into the cuvette 100 after a predetermined time has elapsed from the dispensing of the first reagent. By dispensing the second reagent into the cuvette 100, the reaction between the sample and the reagent starts, and the absorbance of the contents of the cuvette 100 changes. The concentration and activity value of the sample can be determined from such a change in absorbance. In such a measurement, the first probe 11a is washed after dispensing each of the first reagent and the second reagent.

In the case where the sample is urine, the change in absorbance due to the reaction of the sample with the reagent is optically measured, for example, at the colorimetric port P3 b.

When the measurement is completed, the control device 500 discards the cuvette 100 (step S580). Specifically, the controller 500 controls the driving device to move the arm 121, thereby transferring the cuvette 100 from the photometric port P3 to the disposal port P4, releasing the clamp of the arm 121, and loading the cuvette 100 into the disposal port P4. When the cuvette 100 is thrown into the discard port P4, the cuvette 100 (i.e., the used reaction container) is collected in the cuvette discard container 400 (fig. 2).

After step S580, the control device 500 starts the analysis of the next sample specified by the analysis schedule, and therefore the process proceeds to step S510.

In this way, the analyzer 1000 dispenses the sample and the reagent into the cuvette 100, and optically measures the reaction state in the cuvette 100. The measurement result is displayed on the output device 620. The output device 620 displays reagent information, sample information, an analysis schedule, an analysis history, parameters, and the like, in addition to the measurement results. In a state where the analyzer 1000 is powered on, the input device 610 accepts not only the operation of the application 532 by the user but also the operation of the system program 531 by the user. Therefore, the user can edit or delete the reagent information, the sample information, the analysis schedule, the analysis history, the parameters, and the like, and can store these data in an arbitrary recording medium. Also, the user can edit or delete the configuration file of the application 532. Since the user can freely perform operations such as editing, deleting, and saving, there is a concern that personal information may be leaked, or the application 532 and the analysis apparatus 1000 may malfunction. Therefore, in the state where the analyzer 1000 is powered on, the analyzer 1000 restricts the state in which the input device 610 can accept the operation of the system program 531 by the user, thereby preventing leakage of personal information and failure of the analyzer 1000. The limit has a first limit and a second limit. The first restriction is a restriction on the screen provided by the system program 531, in which the user can accept an operation of the system program 531 via the input device 610. The second restriction is a restriction on the screen provided by the application 532 in a state in which the user can accept an operation of the system program 531 via the input device 610. The first and second restrictions are specifically described below.

With reference to fig. 6, a process of limiting a state in which a user can accept an operation of the system program 531 by the input device 610 in a state in which the analysis device 1000 is powered on will be described. Fig. 6 is a flowchart showing a control process of the control device 500 according to embodiment 1. The process shown in fig. 6 is a process performed by control device 500, and CPU510 realizes the process shown in fig. 6 by executing a program stored in storage device 530.

First, the control device 500 determines whether or not an instruction to turn on the power of the analysis device 1000 is accepted (step S605). When an instruction to turn on the power of the analyzer 1000 is received (yes in step S605), the control device 500 starts the system program 531 (step S610).

Next, the control device 500 restricts the state (first restriction) in which the user can accept the operation of the system program 531 by the input device 610 on the screen provided by the system program 531 (step S615). Specifically, after the system program 531 is started, the control device 500 restricts the display on the screen provided by the system program 531 so that the user can be prompted to accept an operation on the system program 531. When the system program 531 starts, a screen provided by the system program 531 is displayed in the output device 620. Therefore, the control device 500 restricts display (for example, display of an operation button for detaching the external storage device, display of a shortcut key for Windows (registered trademark) in the case where the system program 531 is Windows) and the like) which can accept operations (for example, an operation of editing or deleting a configuration file of the application 532, an operation of saving backup data, an operation of securely detaching the external storage device and the like) with respect to the system program 531 to the user from the screen provided by the system program 531.

After the power of the analyzer 1000 is turned on, if a display (for example, a shortcut key of Windows is displayed) is displayed on the screen provided by the system program 531 to suggest to the user that the operation of the system program 531 can be accepted until the power of the analyzer 1000 is turned off after the system program 531 is started, the user can edit or delete the reagent information, the sample information, the analysis schedule, the analysis history, the parameters, and the like, and can store these data in an arbitrary recording medium. Also, the user can edit or delete the configuration file of the application 532. Since the user can freely perform operations such as editing, deleting, and saving, there is a concern that personal information may be leaked, or the application 532 and the analysis apparatus 1000 may malfunction. However, after the system program 531 is started, the analysis device 1000 does not display a screen provided by the system program 531 to suggest to the user that the operation on the system program 531 can be accepted, and therefore leakage of personal information or a failure of the analysis device 1000 can be prevented.

Next, the control device 500 starts the application 532 (step S620). In the analysis device 1000, the first restriction prevents the display of a screen provided by the system program 531, on which the user can accept operations on the system program 531, from being presented after the system program 531 is started. Therefore, after the power of the analysis device 1000 is turned on, the analysis device 1000 starts the application 532 without displaying on the screen provided by the system program 531 that can suggest to the user that an operation on the system program 531 can be accepted, and therefore, the state in which an operation on the system program 531 by the user can be accepted by the input device 610 is restricted until the application 532 is started after the power of the analysis device 1000 is turned on.

Further, in the analysis device 1000, even during the start-up of the application 532, the first restriction prevents the display that can accept the operation of the system program 531 from being presented to the user on the screen provided by the system program 531. Therefore, even during the start of the application 532, the state in which the user can accept the operation of the system program 531 by the input device 610 is limited.

Next, the control device 500 restricts the state (second restriction) in which the user can accept the operation of the system program 531 by the input device 610 on the screen provided by the application 532 (step S625). Specifically, after the application 532 is started, the control device 500 restricts the display of the screen provided by the application 532 so as to allow the user to accept the operation of the system program 531 (for example, displays an operation button for opening the screen provided by the system program 531).

The screen provided by the system program 531 includes, for example, a screen for specifying a storage location of the backup data (hereinafter, also referred to as "storage location specifying screen") and the like. The operation of specifying the save position of the backup data is one of the operations performed by the user on the system program 531. Here, as an example of the second restriction, a description will be given of a restriction on display of an operation button for turning on a storage position designation screen, with reference to fig. 7 to 10.

One of the various functions provided by the application 532 is a function of backing up information related to automatic analysis (for example, reagent information, sample information, analysis schedule, analysis history, setting information (parameters) necessary for analysis, and the like). The backup function includes an automatic backup function of automatically starting backup when the power of the analyzer 1000 is first turned on after day replacement, and a manual backup function of starting backup when a user instructs backup. Here, the user can set the validity/invalidity of the automatic backup function in the environment setting screen provided by the application 532, and can set the validity/invalidity of the manual backup function in the restoration setting screen provided by the application 532.

Fig. 7 is a diagram showing an environment setting screen 650 of the analysis device 1000 according to embodiment 1. Fig. 8 is a diagram showing a recovery setting screen 660 of the analysis device 1000 according to embodiment 1. Fig. 9 is a diagram showing an environment setting screen 650A of an analysis device for comparison with the analysis device 1000 according to embodiment 1. Fig. 10 is a diagram showing a recovery setting screen 660A of an analysis device for comparison with the analysis device 1000 according to embodiment 1.

Referring to fig. 7 and 8, the environment setting screen 650 and the resume setting screen 660 are screens provided by the application 532 and displayed on the output device 620 (fig. 1). An operation button 651 for setting the validity/invalidity of the automatic backup function is displayed on the environment setting screen 650, and the user can activate the automatic backup function by operating (for example, touching a touch panel and clicking with a mouse) the operation button 651 with the input device 610 (fig. 1). Further, an operation button 661 for setting the validity/invalidity of the manual backup function is displayed on the restoration setting screen 660, and the user can activate the manual backup function by operating the operation button 661 with the input device 610 (for example, by touching the touch panel and clicking with the mouse). On the other hand, the operation button for turning on the storage location designation screen is not displayed on the environment setting screen 650 and the resume setting screen 660, and the user cannot arbitrarily designate the storage location of the backup data. In the analysis device 1000, the storage location of the backup data is defined in advance by the configuration file of the application 532.

On the other hand, as shown in fig. 9, on the environment setting screen 650A displayed on the output device of the analysis device for comparison with the analysis device 1000, an operation button 652A for turning on the storage position designation screen is displayed in addition to an operation button 651A capable of setting the validity/invalidity of the automatic backup function. The user can specify the save position of the backup data by operating the operation button 652A (for example, by touching the touch panel and clicking with a mouse) to open the screen provided by the system program. As shown in fig. 10, on a restoration setting screen 660A displayed on an output device of the analysis device to be compared with the analysis device 1000, an operation button 661A for enabling the setting of the validity/invalidity of the manual backup function is displayed, and an operation button 662A for turning on the storage position designation screen is displayed. The user can specify a save position of the backup data by operating the operation button 662A (for example, touching the touch panel and clicking with a mouse) to open a screen provided by the system program.

When an operation button for turning on the save position designation screen is displayed on the environment setting screen 650 and the resume setting screen 660, the user may possibly save the backup data at a save position different from the predetermined save position. The backup data is information related to automatic analysis such as reagent information, sample information, analysis schedule, analysis history, and the like, and contains personal information. Therefore, the act of storing the backup data in a storage location different from the predetermined storage location causes leakage of the personal information. However, the analysis apparatus 1000 does not display an operation button for turning on the saving position designation screen in the screen provided by the application 532, and therefore leakage of personal information can be prevented.

Referring again to fig. 6, next, control device 500 determines whether or not connection of an external storage device to analysis device 1000 is detected (step S630). The external storage device is, for example, a USB (Universal Serial Bus) memory or the like. If connection of the external storage device to the analysis device 1000 is detected (yes in step S630), the control device 500 proceeds to step S635. On the other hand, if connection of the external storage device to the analysis device 1000 is not detected (no in step S630), the control device 500 proceeds to step S640.

In step S635, the control device 500 displays the operation button 671 for safely detaching the external storage device from the analysis device 1000 in the screen provided by the application 532, and shifts the process to step S640.

Here, with reference to fig. 11, a description will be given of a display provided by the application 532 when the external storage device is connected to the analysis device 1000, by taking a case where the external storage device is a USB memory as an example. Fig. 11 is a diagram showing a display in a case where a USB memory is connected to the analysis device 1000 according to embodiment 1. The screen 670 is a screen provided by the application 532 and displayed on the output device 620 (fig. 1). When it is detected that the USB memory is connected to the analyzer 1000, the operation button 671 is displayed on the screen 670. The operation button 671 is a button for instructing execution of processing for safely detaching the USB memory from the analysis apparatus 1000. The user can safely detach the USB memory from the analysis device 1000 by operating (for example, touching the touch panel, clicking with a mouse) the operation button 671 with the input device 610 (fig. 1).

The process for securely unmounting the USB memory from the analysis apparatus 1000 is a process performed by the system program 531, and the operation indicating that the process for securely unmounting the USB memory from the analysis apparatus 1000 is performed is one of the operations performed by the user on the system program 531. In the analysis apparatus 1000, the operation button for safely detaching the USB memory is not displayed on the screen provided by the system program 531 by the first restriction. Therefore, when the USB memory is connected to the analysis apparatus 1000, the analysis apparatus 1000 can safely detach the USB memory from the analysis apparatus 1000 by displaying the operation button 671 on the screen provided by the application 532.

The USB memory is an example, and the case where the operation button 671 for safely detaching the external storage device is displayed on the screen provided by the application 532 is also applicable to external storage devices other than the USB memory.

Referring again to fig. 6, in step S640, the control device 500 determines whether or not an instruction to turn off the power supply of the analysis device 1000 is accepted. An operation button for turning off the power of the analysis apparatus 1000 is displayed on the start/end screen of the application 532, and the user can turn off the power of the analysis apparatus 1000 by operating the operation button with the input apparatus 610.

Here, as another example of the second limitation, a description will be given of a display limitation on the start/end screen of the application 532 with reference to fig. 12 and 13. Fig. 12 is a diagram showing a start/end screen 680 of the application 532 of the analysis device 1000 according to embodiment 1. Fig. 13 is a diagram showing a start/end screen 680A of an application program of an analysis device compared with the analysis device 1000 according to embodiment 1. Start/end screen 680 is a screen provided by application 532 and displayed on output device 620 (fig. 1). On start/end screen 680, operation button 681 for turning off the power of analysis device 1000 is displayed. When the user operates the operation button 681 (for example, touches the touch panel and clicks the mouse) using the input device 610 (fig. 1), the application 532 and the system 531 are terminated, and the power of the analysis device 1000 is turned off. On the other hand, no operation button for displaying a screen provided by the system program 531 after the application 532 is ended is displayed on the start/end screen 680, and the user cannot operate the system program 531 after the application 532 is ended.

On the other hand, on the start/end screen 680A of the application program of the analysis device to be compared with the analysis device 1000 according to embodiment 1, in addition to the operation button 681A for turning off the power supply of the analysis device, an operation button 682A for displaying a screen provided by the system program after the application program is ended is displayed. The user can terminate the application program by operating the operation button 682A with the input device 610 (for example, touching the touch panel and clicking with the mouse), and thereafter operate the system program.

In a case where the system program 531 can be operated after the application 532 is ended, there is a fear that the user operates the system program 531 (for example, an operation of saving backup data in another storage device, an operation of editing or/and deleting a configuration file of the application 532, or the like). Since backup data includes personal information such as reagent information, sample information, analysis schedule, analysis history, and the like, the act of storing the backup data in another storage device becomes a cause of leakage of the personal information. In addition, the operation of editing or/and deleting the configuration file of the application 532 becomes a cause of a failure of the application 532 and even the analysis apparatus 1000. However, the analysis device 1000 does not display a screen provided by the application 532 on which the user is prompted to accept an operation on the system program 531 by the input device 610 after the application 532 is ended (for example, display an operation button for displaying a screen provided by the system program 531 after the application 532 is ended). Thus, the analysis device 1000 restricts the operation of the system program 531 after the application 532 is finished, and thus leakage of personal information or failure of the analysis device 1000 can be prevented.

Referring again to fig. 6, when an instruction to turn off the power supply of analysis device 1000 is received (yes in step S640), control device 500 terminates application 532 (step S645).

Subsequently, the control device 500 ends the system program 531 (step S650). In the analysis device 1000, the first restriction prevents the display of a screen provided by the system program 531, on which the user can be prompted to accept an operation on the system program 531, even after the application program 532 is finished. Therefore, after the application 532 is ended, the analysis device 1000 starts the ending process of the system program 531 without displaying on the screen provided by the system program 531 that the user can accept an operation on the system program 531. Thus, the state in which the user can accept the operation of the system program 531 by the input device 610 is restricted until the system program 531 is ended after the application 532 is ended.

After step S650, the control device 500 ends the series of processes shown in fig. 6.

Through the series of processing shown in fig. 6, the analysis device 1000 can restrict the state in which the user can accept the operation of the system program 531 by the input device 610 from the time when the power of the analysis device 1000 is turned on to the time when the power of the analysis device 1000 is turned off. As a result, leakage of personal information and failure of the analysis device 1000 can be prevented. In addition, since the analysis device 1000 can control the operation for safely detaching the external storage device from the analysis device 1000 to a receivable state, the external storage device can be safely detached from the analysis device 1000.

In addition, although the above example in which the display of the shortcut key of Windows is restricted is given as an example of the first restriction, in the case where the system program 531 is a system program other than Windows (for example, MacOS or the like), the display corresponding to the shortcut key of Windows provided in the system program other than Windows may be restricted.

Further, the first restriction is set to restrict the display in which the user is prompted to accept the operation of the system program 531 on the screen provided by the system program 531, but the acceptance of the pressing operation may be restricted when the Windows button of the keyboard is pressed.

In addition, on start/end screen 680 (fig. 12), not only operation button 681 (fig. 12) for turning off the power of analysis device 1000 but also fields for inputting a user ID, a user name, and a password are displayed. If the input user ID, user name, and password are authenticated, the analysis device 1000 is controlled to be registered with the user ID, and the user can use various functions provided by the application 532.

[ embodiment 2]

In embodiment 1, the analysis device 1000 performs the first restriction and the second restriction regardless of whether the login mode is the user mode or the service mode. In contrast, in the analysis device according to embodiment 2, when the login mode is the user mode, the first restriction and the second restriction are performed, and when the login mode is the service mode, neither the first restriction nor the second restriction is performed. In embodiment 1 and embodiment 2, although the control processing of the control device is different, since the analyzing devices have the same configuration, the same reference numerals are given to the same configuration, and the description thereof will not be repeated. In the following, only the control processing of the control device, which is different from embodiment 1, will be described.

Fig. 14 is a flowchart showing a control process of the control device 500 according to embodiment 2. The process shown in fig. 14 is a process performed by control device 500, and CPU510 realizes the process shown in fig. 14 by executing a program stored in storage device 530. Hereinafter, the same processing as that of embodiment 1 will not be described in detail.

First, the control device 500 determines whether or not an instruction to turn on the power of the analysis device 1000 is accepted (step S1405). When an instruction to turn on the power of the analyzer 1000 is received (yes in step S1405), the control device 500 starts the system program 531 (step S1410).

Next, the control device 500 restricts the state in which the user can accept the operation of the system program 531 by the input device 610 on the screen provided by the system program 531 (step S1415).

Next, the control device 500 starts the application 532 (step S1420).

Next, control device 500 determines whether or not a login operation in the service mode is accepted (step S1425). The service mode is a mode mainly used for maintenance of the analysis device 1000, and the user mode is a mode mainly used for analysis. Control device 500 determines whether or not the login operation in the service mode is accepted based on the user ID input on start/end screen 680. If it is determined that the login operation in the service mode has been accepted (yes in step S1425), the first restriction is lifted (step S1445), and the process proceeds to step S1450. On the other hand, if it is determined that the login operation in the service mode has not been accepted (that is, the login operation in the user mode has been accepted) (no in step S1425), the process proceeds to step S1430.

In step S1430, the control device 500 restricts the state in which the user can accept the operation of the system program 531 by the input device 610 on the screen provided by the application 532.

Next, the control device 500 determines whether or not connection of an external storage device to the analysis device 1000 is detected (step S1435). If connection of the external storage device to the analysis device 1000 is detected (yes at step S1435), the control device 500 proceeds to step S1440. On the other hand, if connection of the external storage device to the analysis device 1000 is not detected (no in step S1435), the control device 500 shifts the process to step S1450.

In step S1440, the control apparatus 500 displays the operation button 671 for safely detaching the external storage apparatus from the analysis apparatus 1000 on the screen provided by the application 532, and the process proceeds to step S1450.

In step S1450, the control device 500 determines whether or not an instruction to turn off the power supply of the analysis device 1000 is accepted. When an instruction to turn off the power of the analysis device 1000 is received (yes at step S1450), the control device 500 terminates the application 532 (step S1455).

Next, the control device 500 ends the system program 531 (step S1460), and ends the series of processing shown in fig. 14.

As is clear from fig. 6 and 14, the control processing of embodiment 2 differs from the control processing of embodiment 1 in the following two points. First, after the application 532 is started (step S1420), it is determined whether or not the login operation in the service mode is accepted (step S1425), and if it is determined that the login operation in the service mode is accepted (yes in step S1425), the first restriction is cancelled (step S1445). Second, when it is determined that the login operation in the service mode is accepted (yes in step S1425), the second restriction is not imposed.

Through a series of processes shown in fig. 14, in the analysis device 1000 according to embodiment 2, the first restriction and the second restriction are performed when the user mode is used for registration, and neither of the first restriction and the second restriction is performed when the service mode is used for registration. When performing maintenance by logging in the service mode, the system program 531 may have to be operated. According to embodiment 2, when the system program 531 is registered in the service mode, the input device 610 is not limited to a state in which the user can accept the operation of the system program 531, and therefore, the maintenance can be performed efficiently. Further, when the user mode is registered, the input device 610 is restricted from accepting the user operation of the system program 531, and therefore leakage of personal information and failure of the analysis device 1000 can be prevented.
