Description

  Embodiments described herein relate generally to an automatic analyzer.

  The automatic analyzer is a device that measures the concentration and activity of a substance to be measured and an enzyme in a test sample. Specifically, the automatic analyzer dispenses a test sample such as human blood or urine and a reagent in a reaction tube, and after stirring and mixing, reacts at a constant temperature and measures changes caused by this reaction. .

  The automatic analyzer issues a warning when an error occurs (for example, the dispensing arm does not move, or there is no pure water used for cleaning), and the operator is made aware that the error has occurred. A function is provided.

  Examples of the warning include a method of repeatedly popping up a window indicating that an error has occurred on the entire display unit of the automatic analyzer every predetermined time.

JP 2005-265743 A

  In laboratories where automatic analyzers are used, a single operator often operates several devices simultaneously. Therefore, even if an error occurs in the automatic analyzer that is not operated, there is a possibility that it will be delayed to notice. Therefore, it is desirable that the warning be made in such a way that an error can be recognized early.

  Here, when operating the automatic analyzer, it may be troublesome for the operator to give a warning in the same manner as when the automatic analyzer is not operated. For example, when popping up a window on the entire display to warn of an error, an automatic analyzer that is away from the operator (an automatic analyzer that is not operating) displays a large window. An error can be easily recognized. On the other hand, if the same pop-up display is made on the automatic analyzer that the operator is operating while looking at the display unit, it is troublesome because it is necessary to stop the operation and close the window. As described above, the conventional warning method having the same warning mode may be troublesome for the operator who operates the automatic analyzer.

  The present embodiment has been made to solve such a problem, and an object thereof is to provide an automatic analyzer that issues a warning in such a manner that an error can be recognized at an early stage without bothering an operator. And

  In order to solve the above problems, the automatic analyzer described in the embodiment includes an analysis unit, a warning unit, an operation unit, a recording unit, a detection unit, and a control unit. The warning means is configured to output warning information. The recording means records the timing when the operation by the operation means is performed. The detecting means detects the occurrence of an error. The control means determines whether or not the latest timing recorded by the recording means exceeds a threshold when the occurrence of an error is detected. If the threshold is not exceeded, warning information is displayed in the first mode. Control is performed to output the warning information to the warning means in the second mode when the warning means outputs the threshold information.

<First Embodiment>
The configuration of the automatic analyzer 1 according to the first embodiment will be described with reference to FIGS. 1 to 6. In this embodiment, a rack sampler type automatic analyzer will be described, but the configuration of this embodiment can be applied to other types of automatic analyzers such as a disk sampler type.

  As shown in FIG. 1, the automatic analyzer 1 includes an analysis unit 2, an input unit 3, a display unit 4, an audio output unit 5, and a control unit 6.

[Analysis unit]
FIG. 2 is a view of the analysis unit 2 according to this embodiment as viewed from above. The analysis unit 2 is a unit that measures standard samples and test samples.

  The analysis unit 2 includes a reagent bottle 20a, a reagent storage 20b / 20c, a reagent storage cover 20d, a reaction line 21, a test sample container 22, a rack sampler 23, a dispensing arm 24a / 24b, a sampling arm 25, a stirring unit 26, A photometric unit 27 and a cleaning unit 28 are included. Furthermore, the analysis unit 2 is provided with an apparatus cover 29 (in FIG. 2, each component in the analysis unit 2 is illustrated by broken lines).

  The reagent bottle 20a is a container in which reagents that react with various components of the test sample are stored. The reagent bottle 20a is installed in the reagent storages 20b and 20c while being accommodated in a reagent rack (not shown). Reagent storage covers 20d that can be opened and closed are respectively provided in the reagent storage 20b and 20c (in FIG. 2, the reagent storage cover 20d is shown by a broken line so that the arrangement of the reagent bottles 20a in the reagent storage 20b and 20c can be seen. ) The opening / closing operation of the reagent storage cover 20d is detected by a micro switch (not shown) or the like. In the present embodiment, the reagent storage cover 20d is an example of the “operation means”. The opening and closing of the reagent storage cover 20d is an example of “operation by the operation means”.

  A plurality of reaction tubes (not shown) are arranged on the circumference of the reaction line 21. A reaction tube is a container used when a test sample and a reagent are reacted.

  The test sample container 22 is a container for storing the test sample. A plurality of sample containers 22 are arranged on the rack sampler 23.

  The reagent in the reagent bottle 20a is dispensed into the reaction tube by the dispensing arm 24a or the dispensing arm 24b. The test sample in the test sample container 22 is dispensed into the reaction tube by the sampling arm 25.

  The reaction tube into which the test sample and the reagent are dispensed is transported along the reaction line 21 and moved to the position of the stirring unit 26. The agitating unit 26 agitates the reaction tube containing the test sample and the reagent, and mixes the test sample and the reagent.

  The stirred reaction tube is moved to the position of the photometric unit 27. The photometric unit 27 performs component analysis of the test sample by irradiating the reaction tube with light and measuring the absorbance of the mixed solution of the test sample and the reagent.

  The cleaning unit 28 cleans the reaction tube after the component analysis is completed and the mixed solution is discarded. Pure water and detergent used for cleaning are stored in a tank (not shown) or the like provided in the automatic analyzer 1.

  When the analysis of all the test sample containers 22 arranged on the rack sampler 23 is completed, the rack sampler 23 is taken out from the analysis unit 2. When there is another test sample to be analyzed, the rack sampler 23 in which another test sample container 22 containing the test sample is placed can be set in the analysis unit 2 and the analysis can be continued. The removal or setting of the rack sampler 23 is detected by a micro switch (not shown) or the like. In this case, the rack sampler 23 is an example of “operation means”. Further, taking out and setting the rack sampler 23 is an example of “operation by the operation means”.

  The device cover 29 is provided so that it can be opened and closed. By opening the apparatus cover 29, it is possible to perform operations on the analysis unit 2 (addition of reagents, arrangement of the rack sampler 23, etc.). The opening / closing operation of the device cover 29 is detected by a micro switch (not shown) or the like. In the present embodiment, the device cover 29 is an example of the “operation means”. The opening and closing of the device cover 29 is an example of “operation by the operating means”.

[Input unit]
The input unit 3 is used for performing operation input to the automatic analyzer 1. The input unit 3 includes input means such as a keyboard and a mouse. Alternatively, the input unit 3 may include a GUI (Graphical User Interface) displayed on the display unit 4. In the present embodiment, the input unit 3 is an example of “operation means”. An input operation by the input unit 3 (for example, key input by a keyboard) is an example of “operation by operation means”.

[Display unit]
The display unit 4 is a display device such as a monitor that displays an analysis result by the automatic analyzer 1, an input screen by the input unit 3, and warning information for warning an error. In the present embodiment, the display unit 4 is an example of a “display unit”.

[Audio output unit]
The audio output unit 5 includes audio output means such as a speaker. The voice output unit 5 outputs voice information as warning information for warning an error of the automatic analyzer 1. In the present embodiment, the audio output unit 5 is an example of “warning means”.

[Controller unit]
As shown in FIG. 3, the control unit 6 includes a main control unit 61, a recording unit 62, a detection unit 63, a determination unit 64, and a warning control unit 65.

  The main control unit 61 performs various controls of the automatic analyzer 1. For example, based on an instruction input from the input unit 3, the main control unit 61 starts analysis by the analysis unit 2.

  In the present embodiment, the main control unit 61 transmits operation information by the operation means to the recording unit 62. “Operation information” is information including operation details. For example, when the reagent storage cover 20d is opened, based on a detection signal from a micro switch that detects the operation of the reagent storage cover 20d, the main control unit 61 records operation information indicating that the reagent storage cover 20d has been opened and closed. 62.

  The recording unit 62 records the timing when the operation by the operation unit is performed. The “timing” includes any concept of an elapsed time from a certain time point (for example, a time point when the automatic analyzer 1 is turned on) and a time when an operation by the operation unit is performed. The recording unit 62 includes time measuring means (not shown) such as a timer. For example, the recording unit 62 refers to a timer when receiving operation information from the operation means from the main control unit 61 and records the time indicated by the timer in association with the operation information.

  In addition, when receiving a plurality of pieces of operation information by different operation means, the recording unit 62 can distinguish and record the operation timing by each operation means. For example, when the operation information regarding the key operation by the input unit 3 and the operation information regarding the reagent storage cover 20d are received, the timing of the key operation and the operation timing of the reagent storage cover 20d are distinguished and recorded.

  The recording by the recording unit 62 may record all timings every time an operation is performed, or may update and record only the latest timing. In the present embodiment, the recording unit 62 is an example of a “recording unit”.

  The detector 63 detects the occurrence of an error that occurs in the automatic analyzer 1. The “error” is a factor that hinders the analysis work by the automatic analyzer 1 and a factor that adversely affects the analysis result. For example, it relates to an analysis environment such as a mechanical error such as the dispensing arm 24a not moving, an error related to consumables such as the absence of detergent or pure water used for cleaning, or the temperature inside the automatic analyzer 1 being too high. Such as an error. In the present embodiment, the detection unit 63 is an example of a “detection unit”.

  The determination unit 64 determines whether or not the latest timing recorded by the recording unit 62 exceeds the threshold when the detection unit 63 detects the occurrence of an error. Specifically, the determination unit 64 subtracts the latest timing time counted by the timer from the time when the detection unit 63 detects the occurrence of the error, and determines whether the value exceeds the threshold value. . “Latest timing” is the time (or time) at which an operation was last performed as viewed from the time of error occurrence. The “threshold value” is a value serving as a reference for changing the mode of the warning information. The threshold value can be arbitrarily set using the input unit 3 and the display unit 4 as appropriate during analysis by the automatic analyzer 1. Alternatively, a plurality of preset threshold values may be stored in a storage unit (not shown) or the like, and the control unit 6 may selectively read and apply in accordance with the analysis content or the like.

  The warning control unit 65 controls the warning unit based on the determination result of the determination unit 64 to output warning information. Specifically, the warning control unit 65 outputs warning information to the warning means (for example, the display unit 4) in the first mode (for example, icon display) when the determination unit 64 determines that the threshold value is not exceeded. Output. Moreover, the warning control part 65 makes a warning means (for example, audio | voice output unit 5) output warning information in a 2nd aspect (for example, audio | voice), when the determination part 64 determines that it exceeds the threshold value. The output mode of the warning information can be set using the input unit 3 and the display unit 4 as appropriate at the time of analysis by the automatic analyzer 1. Further, a plurality of preset output modes may be stored in a storage unit (not shown) or the like, and the control unit 6 may selectively read out and apply in accordance with the analysis content or the like. In the present embodiment, the determination unit 64 and the warning control unit 65 are examples of “control means”.

  Further, the display unit 4 in the present embodiment can display warning information for warning the occurrence of an error by displaying a new object or changing the display mode of an existing object. For example, the display unit 4 performs pop-up display using a window that presents character string information indicating the warning content as warning information. Further, the display unit 4 turns on and blinks an icon indicating a warning content as warning information for warning an error of the automatic analyzer 1. That is, in the present embodiment, the display unit 4 is an example of “warning means”.

[Setting example of threshold and warning information output mode]
Here, a setting example of the output mode of the threshold value and warning information will be described with reference to FIG. FIG. 4 is an example of the display screen I of the display unit 4. On the display screen I, an operation content column O by the operating means of the automatic analyzer 1 and a warning information output mode column D are displayed.

  In the present embodiment, the operation content column O displays four operations: key operation o1 by the input unit 3, operation o2 of the device cover 29, addition operation o3 of the rack sampler 23, and operation o4 of the reagent storage cover 20d. . A check box C and an input field E for inputting a threshold value are provided for each operation content. The operator can select an operation for recording timing in the recording unit 62 by checking a check box C corresponding to the desired operation content. The threshold value can be input by time, for example. The operation content is not limited to this. Any operation on the automatic analyzer 1 can be adopted as the operation content.

  In the present embodiment, a window pop-up display d1, a warning sound d2, and an icon display d3 are displayed in the warning information output mode column D. Each of the pop-up display d1, the warning sound d2, and the icon display d3 is provided with a check box C for selecting and designating an output mode according to whether or not the timing set in the operation content column O is equal to or greater than a threshold value. Yes.

  For example, as shown in FIG. 4, the operator checks the check box C of the key operation o1 on the display screen I, and inputs “5 minutes” as the threshold value. Further, the operator checks “lighting” of the icon display d3 as a warning information mode when the threshold value is below the threshold value, and checks “high” of the warning sound d2 as a warning information mode when the value is above the threshold value. .

<Operation>
The operation of the automatic analyzer 1 according to this embodiment will be described with reference to FIGS. 5 and 6.

  Before starting the analysis by the automatic analyzer 1, the operator sets the output mode of the threshold value and the warning information by using the input unit 3 or the like (S10). Here, it is assumed that the output mode of the threshold value and the warning information is set as shown in FIG.

  After the setting in S10 is completed, analysis by the automatic analyzer 1 is started (S11). The recording unit 62 starts timing by the timer and records the timing every time the operation by the key operation o1 set in S10 is performed (S12).

  Here, when an error is detected by the detection unit 63 (S13), the determination unit 64 determines whether or not the latest timing recorded in S12 exceeds the threshold set in S10 (S14). Specifically, the determination unit 64 subtracts the latest timing time recorded in S12 (the latest timing time measured by the timer) from the time in S13 (the time when the occurrence of the error is detected). , It is determined whether or not the value exceeds a threshold value (5 minutes).

  When it is determined that the latest timing of the operation by the key operation o1 recorded in S12 does not exceed the threshold value (in the case of N in S14), the warning control unit 65 sets the warning information output mode set in S10. Based on the warning information for the error, the icon W3 is turned on on the display unit 4 (S15, first mode, see FIG. 6).

  On the other hand, when it is determined that the latest timing of the operation by the key operation o1 recorded in S12 exceeds the threshold value (Y in S14), the warning control unit 65 outputs the warning information set in S10. Based on the mode, a warning sound is output to the audio output unit 5 as warning information for the error (S16, second mode).

<Action and effect>
The operation and effect of this embodiment will be described.

  The automatic analyzer 1 according to the present embodiment includes an analysis unit, a warning unit, an operation unit, a recording unit (recording unit 62), a detection unit (detection unit 63), and a control unit. The warning means can output warning information. The recording means records the timing when the operation by the operation means is performed. The detecting means detects the occurrence of an error. The control means determines whether or not the latest timing recorded by the recording means exceeds a threshold when the occurrence of an error is detected. If the threshold is not exceeded, warning information is displayed in the first mode. Control is performed to output the warning information to the warning means in the second mode when the warning means outputs the threshold information.

  Therefore, since the manner in which the warning information is output can be changed depending on the timing when the operation means is operated, the warning is issued in such a manner that the occurrence of the error can be recognized at an early stage without bothering the operator. Can be done. For example, when the operator is performing an operation on the display screen of the display unit 4, an icon is lighted small below the display screen as a warning information output mode. On the other hand, when the operator is away from the automatic analyzer 1 and operates another automatic analyzer or the like, a warning sound is generated as an output mode of warning information. Therefore, the operator can recognize the occurrence of the error at an early stage without being hindered from the current operation.

Second Embodiment
With reference to FIG.7 and FIG.8, the structure of the automatic analyzer 1 which concerns on 2nd Embodiment is demonstrated. A description of the same configuration as that of the first embodiment may be omitted.

  For example, as in the first embodiment, when the error occurs at the time when the key operation o1 has been performed for five minutes or more since the last time, the warning control unit 65 displays an icon (first display) as warning information. The sound output unit 5 is caused to output a warning sound (second aspect) instead of the above aspect.

  However, even when no key operation is performed, the operator may be performing some operation on the automatic analyzer 1. For example, there are cases where the reagent storage cover 20d is opened and closed to replace the reagent bottle 20a, and the rack sampler 23 is replaced. In such a case, issuing a warning with a loud warning sound may be troublesome for an operator working beside the automatic analyzer 1.

  In the present embodiment, a configuration is described in which a warning is given by a method that can recognize the occurrence of an error at an early stage without bothering the operator even in such a case. In the present embodiment, the key operation is described as “first operation”, and the operation of the reagent storage cover 20d is described as “second operation”. The first operation and the second operation can be set in advance on a setting screen such as the display screen I in the first embodiment, for example.

  In the present embodiment, the icon display is the “first mode” as a mode for outputting the warning information. Further, among the modes of outputting voice information as warning information, the warning sound (high) will be described as “second mode” and the warning sound (low) will be described as “third mode”. The first to third aspects can be set in advance on a setting screen such as the display screen I in the first embodiment, for example.

  As shown in FIG. 7, in the present embodiment, the control unit 6 includes an operation determination unit 66. The operation determining unit 66 determines whether the second operation is actually performed when the timing of the latest first operation exceeds the threshold by the determining unit 64. The determination result by the operation determination unit 66 is sent to the warning control unit 65. The “actually” includes not only the case where the operating means is actually operated at the time of occurrence of the error but also the case where there is a high possibility that the operating means is being operated. For example, there is a high possibility that some work is being performed on the reagent containers 20b and 20c from when the reagent container cover 20d is opened to when it is closed. Therefore, when the reagent storage cover 20d is already opened at the time of occurrence of the error, the operation determining unit 66 determines that “the second operation is being performed”. An arbitrary operation is set in advance as the second operation to be determined by the operation determining unit 66.

  If the operation determination unit 66 determines that the second operation is actually being performed, the warning control unit 65 causes the warning unit to output the warning information in the third mode instead of the first mode. If the time during which no key operation is performed exceeds the threshold and the operation determination unit 66 determines that the second operation is not currently being performed, the warning control unit 65 displays warning information as a warning sound. (Large) is output to the audio output unit 5 (second mode). On the other hand, when the operation determining unit 66 determines that the second operation is actually being performed, the operator is likely to be working near the automatic analyzer 1. Therefore, the warning control unit 65 causes the audio output unit 5 to output the warning information with a warning sound (small) instead of the pop-up display by the window (third mode).

<Operation>
The operation of the automatic analyzer 1 according to this embodiment will be described with reference to FIG.

  Before starting the analysis by the automatic analyzer 1, the operator sets the output mode of the threshold value and the warning information by using the input unit 3 or the like (S20). Here, it is assumed that the threshold is set to 5 minutes for the key operation. It is assumed that the warning information output mode is set as described above.

  After the setting in S20 is completed, analysis by the automatic analyzer 1 is started (S21). The recording unit 62 starts timing by the timer and records the timing every time the operation by the key operation o1 set in S20 is performed (S22).

  Here, when an error is detected by the detection unit 63 (S23), the determination unit 64 determines whether or not the latest timing recorded in S22 exceeds the threshold set in S20 (S24).

  When it is determined that the latest timing recorded in S22 does not exceed the threshold value (in the case of N in S24), the warning control unit 65 warns the error based on the warning information output mode set in S20. Then, the icon W3 is turned on on the display unit 4 (S25, first mode).

  On the other hand, when it is determined that the latest timing recorded in S22 exceeds the threshold value (Y in S24), the operation determination unit 66 operates the reagent storage cover 20d (second operation). It is determined whether or not (S26).

  When it is determined that the operation of the reagent storage cover 20d is not performed (N in S26), the warning control unit 65 warns as warning information for an error based on the warning information output mode set in S20. (Large) is output to the audio output unit 5 (S27, second mode).

  On the other hand, if it is determined that the operation of the reagent storage cover 20d is being performed (Y in S26), the warning control unit 65 uses the warning information output mode set in S20 as warning information for an error. A warning sound (small) is output to the audio output unit 5 (S28, third mode).

  The second operation not only sets a specific operation (operation of the reagent storage cover 20d) as in the present embodiment, but also the first operation among the operations performed on the automatic analyzer 1. It is also possible to target all except.

<Action and effect>
The operation and effect of this embodiment will be described.

  In the automatic analyzer 1 according to the present embodiment, the operation by the operation means includes at least a first operation and a second operation that are different from each other. The recording means (recording unit 62) records the timing of the first operation and the timing of the second operation separately. When the occurrence of an error is detected, the control means sets the warning information to the first mode when the timing of the latest first operation exceeds the threshold and the second operation is actually being performed. Instead, the warning means is output in the third mode.

  Therefore, since the output mode of the warning information is changed depending on whether or not the second operation is being performed, the warning can be performed in such a way that the occurrence of the error can be recognized at an early stage without bothering the operator. . For example, when the operator is away from the automatic analyzer 1 and operates another automatic analyzer or the like, a warning sound is generated with a large volume as an output mode of warning information. On the other hand, when the operator is operating beside the automatic analyzer 1 (for example, opening and closing of the reagent storage cover 20d), a warning sound is generated with a small volume as an output mode of warning information. Therefore, the operator can recognize the occurrence of the error at an early stage without being hindered from the current operation.

<Third Embodiment>
The configuration of the automatic analyzer 1 according to the third embodiment will be described with reference to FIGS. 9 and 10. A description of the same configuration as in the first embodiment and the second embodiment may be omitted.

  For example, an error relating to the reagent storage 20b (for example, the temperature adjustment mechanism fails and the temperature in the reagent storage 20b cannot be maintained) occurs during the operation of opening the reagent storage cover 20d of the reagent storage 20b and replacing the reagent bottle 20a. In such a case, the operator needs to recognize the error early and eliminate it. On the other hand, if the error is not related to the reagent storage 20b that is currently working, it is sufficient that the error can be found after the work in the reagent storage 20b is completed.

  In the present embodiment, a configuration is described in which a warning is given by a method that can recognize the occurrence of an error at an early stage without bothering the operator even in such a case. In the present embodiment, as in the second embodiment, the key operation is described as “first operation”, and the operation of the reagent storage cover 20d is described as “second operation”.

  In the present embodiment, as in the second embodiment, the icon display is the “first aspect” as an aspect for outputting the warning information. Further, as in the second embodiment, among the modes of outputting the voice information as the warning information, the warning sound (large) is described as the “second mode”, and the warning sound (small) is described as the “third mode”. . Furthermore, the emergency warning sound will be described as a “fourth aspect” among the aspects in which sound information is output as the warning information. The “emergency warning sound” is different from the warning sound (high), the warning sound (small), and the sounding timing (in the case of an emergency warning sound, the sound is frequently repeated).

  As shown in FIG. 9, in the present embodiment, the control unit 6 includes an error determination unit 67. When the operation determination unit 66 performs the second operation, the error determination unit 67 determines whether the operation is related to the error detected by the detection unit 63. Specifically, table information in which an operation by the operation means (second operation) and an error type (error content or error part) are associated is stored in advance in a storage unit (not shown). The error determination unit 67 acquires information related to the error detected from the detection unit 63 (for example, error type) and information related to the second operation (for example, the type of second operation) from the operation determination unit 66, respectively. The error determination unit 67 applies the acquired error information and the second operation information to the table information, and determines whether or not they are associated with each other. The determination result by the error determination unit 67 is sent to the warning control unit 65.

  The warning control unit 65 changes the output mode of the warning information when the error determination unit 67 determines that the second operation and the error detected by the detection unit 63 are related. Specifically, the warning control unit 65 causes the audio output unit 5) to output an emergency warning sound (fourth mode) instead of the icon display (first mode).

<Operation>
The operation of the automatic analyzer 1 according to this embodiment will be described with reference to FIG.

  Before starting the analysis by the automatic analyzer 1, the operator sets the output mode of the threshold value and the warning information by using the input unit 3 or the like (S30). Here, it is assumed that the threshold is set to 5 minutes for the key operation. It is assumed that the warning information output mode is set as described above.

  After the setting in S30 is completed, analysis by the automatic analyzer 1 is started (S31). The recording unit 62 starts timing by the timer and records the timing every time the operation by the key operation o1 set in S30 is performed (S32).

  If an error is detected by the detection unit 63 (S33), the determination unit 64 determines whether the latest timing recorded in S32 exceeds the threshold set in S30 (S34).

  When it is determined that the latest timing recorded in S32 does not exceed the threshold value (in the case of N in S34), the warning control unit 65 warns information about an error based on the output mode of the warning information set in S30. Then, the icon W3 is turned on on the display unit 4 (S35, first mode).

  On the other hand, when it is determined that the latest timing recorded in S32 exceeds the threshold value (Y in S34), the operation determination unit 66 determines whether the reagent storage cover 20d is operated. (S36).

  When it is determined that the reagent storage cover 20d is not operated (N in S36), the warning control unit 65 generates warning sound as warning information for the error based on the warning information output mode set in S30. (Large) is output to the audio output unit 5 (S37, second mode).

  On the other hand, when it is determined that the operation of the reagent storage cover 20d is performed (Y in S36), the error determination unit 67 relates to the error detected by the detection unit 63 in the operation of the reagent storage cover 20d. Whether or not (S38).

  When it is determined that the operation of the reagent storage cover 20d is not related to the error detected by the detection unit 63 (N in S38), the warning control unit 65 is based on the output mode of the warning information set in S30. A warning sound (small) is output to the audio output unit 5 as warning information for the error (S39, third mode).

  On the other hand, when it is determined that the operation of the reagent storage cover 20d is related to the error detected by the detection unit 63 (Y in S38), the warning control unit 65 is based on the output mode of the warning information set in S30. Then, an emergency warning sound is output to the voice output unit 5 as warning information for the error (S40, fourth mode).

<Action and effect>
The operation and effect of this embodiment will be described.

  In the automatic analyzer 1 according to the present embodiment, the control unit changes the output mode of the warning information by the warning unit based on the operation by the operation unit and the type of the detected error.

  Accordingly, since the output mode of the warning information is changed depending on whether or not the second operation is related to the error, the warning is issued in such a way that the occurrence of the error can be recognized at an early stage without bothering the operator. Can do. For example, when the operator is away from the automatic analyzer 1 and operates another automatic analyzer or the like, a warning sound is generated as an output mode of warning information. On the other hand, when an operator performs an operation (for example, opening and closing of the reagent storage cover 20d) beside the automatic analyzer 1, an error warning sound is generated as an output mode of warning information when an error related to the operation occurs. Let Therefore, the operator can recognize the occurrence of the error at an early stage without being hindered from the current operation.

<Modification 1>
There are various methods for outputting the warning information.

  When a pop-up display of a window is used as the output mode, the window display mode can be changed. For example, the display size of the window, the font size of the character string information presented in the window, the color of the window, and the like can be changed depending on whether or not the latest timing recorded by the recording unit 62 exceeds a threshold value.

  When icon display is used as the output mode, the icon display mode can be changed. For example, the icon size, shape, color, lighting / flashing, lighting / flashing time, lighting / flashing timing, etc. can be changed depending on whether or not the latest timing recorded by the recording unit 62 exceeds a threshold value. it can.

  When voice information is used as the output mode, the voice generation mode can be changed. For example, the loudness, timing, pattern, sound itself, etc. can be changed depending on whether or not the latest timing recorded by the recording unit 62 exceeds a threshold value.

  Furthermore, it is possible to change the output mode of the warning information according to the part of the error and the content of the error. For example, in the third embodiment, when an error related to the operation of the reagent storage cover 20d occurs, an emergency warning sound is generated. Among the related errors, there are an error related to the temperature adjustment mechanism and an error related to the dispensing arm 24a. Different emergency warning sounds. Thus, by distinguishing the emergency warning sound, the operator can easily recognize where the error has occurred in the portion related to the operation of the reagent storage cover 20d.

<Modification 2>
In the above embodiment, a plurality of operation details can be selected in the operation content column O. For example, in the setting example of the output mode of the threshold value and warning information in the first embodiment, it is assumed that the key operation o1 and the operation o2 of the device cover 29 are selected and the threshold values are set to 5 minutes and 30 minutes, respectively.

  In this case, if an error occurs in the automatic analyzer 1, the time when the error occurs is within 5 minutes after the last key operation o1 or 30 minutes after the operation o2 of the device cover 29 is performed. If within, the warning control unit 65 controls the display unit 4 to turn on the icon W3. On the other hand, when the time when the error occurs is 5 minutes or more after the key operation o1 is last performed and 30 minutes or more after the operation o2 of the device cover 29 is performed, the warning control unit 65 The audio output unit 5 is controlled to generate a warning sound.

  In the above embodiment, a plurality of modes can be selected as the output mode of the warning information. For example, on the display screen I, when “Yes” of the pop-up display d1 and “Lighting” of the icon display d3 are checked as the first mode, the pop-up display of the window W1 and the lighting of the icon W3 are performed as shown in FIG. Done at the same time. In this case, the error part and the specific contents of the error can be displayed in the window W1.

  According to the automatic analyzer of at least one embodiment described above, when the occurrence of an error is detected, it is determined whether or not the latest timing recorded by the recording unit exceeds the threshold, and the threshold is exceeded. If there is a control means for controlling the warning information to be output to the warning means in the first mode when there is not, and the warning information to be output to the warning means in the second mode if the threshold is exceeded, It is possible to issue a warning in such a way that an error can be recognized at an early stage without bothering the user.

  Although several embodiments of the present invention have been described, these embodiments are presented by way of example and are not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, replacements, and changes can be made without departing from the scope of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
