Description

  The present invention mainly relates to a sample analyzer. Specifically, the present invention relates to a function for supporting or assisting input of an analysis order when automatic analysis is executed in a sample analyzer.

  For example, in order to examine cholesterol levels and the like using plasma, serum, urine and the like as a sample, a sample analyzer such as a biochemical automatic analyzer is used. In the biochemical automatic analyzer, a specimen is reacted with a predetermined reagent, the absorbance of the reaction solution is measured, and a test result such as a cholesterol value is obtained from the obtained data.

  In this type of analyzer, deterioration of reagents, changes in the state of the apparatus, etc. affect the test results. Therefore, in order to maintain the accuracy of the inspection result, operations such as calibration and accuracy management are performed regularly or irregularly. Calibration is an operation of creating a calibration curve by measuring a standard sample having a known concentration with a biochemical automatic analyzer. In addition, accuracy management refers to whether or not the analysis accuracy is maintained by examining a control sample of a known concentration with a biochemical automatic analyzer and determining whether or not the test result is within a predetermined range. This is a determination operation.

  The frequency with which the above calibration and accuracy management are performed is ultimately left to the user's judgment, and the manufacturer of the biochemical automatic analyzer cannot be determined uniformly. Therefore, the user needs to plan a schedule for performing calibration and accuracy management, and perform calibration and accuracy management according to the schedule. However, if all management of this schedule is left to the user, the user may forget to execute calibration and accuracy management. In this case, the accuracy of the analysis result cannot be guaranteed. In particular, since the biochemical automatic analyzer generally uses a plurality of types of reagents, calibration and accuracy management must be performed for each measurement item, which makes it difficult to manage the schedule. .

  In this regard, Patent Document 1 discloses an automatic analyzer having a function of automatically creating and displaying a calibration and accuracy management execution schedule table for a certain period in the future. With this, Patent Document 1 can appropriately design an analysis schedule for each date and assign an inspection engineer at each user facility, and efficiently prepare reagents and inventory that are necessary for calibration and accuracy management. Can be done automatically.

  Patent Document 2 discloses an automatic analyzer support system that displays an analysis item name and an analysis unit name on which calibration or accuracy management of the analysis item is to be performed on a screen in accordance with a user instruction. is doing. Thus, the patent document 1 can easily notify the operator of the analysis items to be calibrated or controlled in accuracy, and can accurately perform the predetermined calibration or accuracy control for the specific analysis unit in which the necessity arises. It can be executed.

JP 2009-168730 A JP-A-10-339732

  By the way, in a biochemical analyzer that performs automatic analysis by setting a plurality of samples, it is necessary to set in advance information (analysis order) on what sample should be analyzed. Such an operation is called order registration. By performing order registration in this manner, for example, even when samples having different test items are mixed, analysis can be performed appropriately.

  Such order registration is also required for calibration and accuracy management. That is, when calibration is performed, a sample having a known concentration is set in the biochemical automatic analyzer, and the sample is registered as an order as a standard sample for calibration. When performing quality control, a sample having a known concentration is set in the biochemical automatic analyzer, and the sample is registered as an order as a control sample for quality control. Here, as described above, since calibration and accuracy management should be performed periodically, it is necessary to periodically repeat the order registration of standard samples and control samples. However, if the user has to perform the same order registration for the standard sample and the control sample every time, it is troublesome for the user and there is a risk of an input error.

  In this respect, since the automatic analyzer disclosed in Patent Document 1 only displays the calibration and accuracy management execution schedule table, the user can see the standard sample and the control after viewing the displayed schedule table. You must register the sample order yourself. Therefore, the configuration of Patent Document 1 cannot solve the problem of reducing labor for order registration and reducing input errors.

  On the other hand, Patent Literature 2 discloses a configuration in which calibration or accuracy management is activated when a user operates an appropriate button when calibration or accuracy management is necessary. However, this configuration lacks flexibility because the standard sample and the control sample cannot be pre-ordered.

  The present invention has been made in view of the above circumstances, and a main object of the present invention is to provide a sample analyzer that can reduce a burden on the user and an input error when performing order registration.

Means and effects for solving the problems

  The problems to be solved by the present invention are as described above. Next, means for solving the problems and the effects thereof will be described.

  According to the first aspect of the present invention, the analysis of the sample is performed based on the sample tube setting unit capable of setting a plurality of sample tubes containing the sample and at least one test item corresponding to each sample. And a sample analysis device configured as follows, and a sample analyzer configured as follows. That is, the sample analyzer includes an analysis order setting unit, an analysis order information registration unit, a current value acquisition unit, and an analysis order information selection unit. The analysis order setting unit sets an analysis order including the position of the sample tube in which the sample is accommodated and the analysis content of the sample. The analysis order information registration unit registers analysis order information in which the analysis order is associated with an application condition. The current value acquisition unit acquires a current value corresponding to the application condition. The analysis order information selection unit selects the analysis order information whose application condition matches the current value.

  In this way, by creating analysis order information in advance and applying the analysis order information to create an analysis order, it is possible to reduce the effort that a user manually inputs, Input mistakes can be prevented. Further, by registering the analysis order information in association with the condition, the analysis order information that satisfies the condition can be automatically selected.

  The sample analyzer preferably includes an analysis order information application unit that creates the analysis order based on the analysis order information selected by the analysis order information selection unit.

  As a result, the analysis order information that satisfies the condition is automatically applied to create the analysis order, so that an appropriate analysis order can be created.

  The sample analyzer is preferably configured as follows. That is, the analysis content of the sample includes at least information indicating the type of the sample. As the type of the sample, at least one of a standard sample for calibration and a control sample for accuracy control can be designated.

  That is, since calibration and accuracy management are routine analysis, registration of the sample for calibration and accuracy management in the analysis order can be saved by registering in the analysis order information. For example, if the analysis order information is registered by designating the date and time when calibration and accuracy management are performed as application conditions, forgetting to perform calibration and accuracy management can be prevented.

  The sample analyzer is preferably configured as follows. That is, when an analysis order is created based on analysis order information including information on the sample designated as the standard sample and calibration is performed based on the analysis order, if the calibration fails, the next time When generating an analysis order, the analysis order information selection unit selects the analysis order information regardless of whether the application condition matches the current value.

  Thereby, when calibration fails, calibration can be re-executed at the next analysis.

  The sample analyzer is preferably configured as follows. That is, when an analysis order is created based on the analysis order information including the information of the sample designated as the control sample, and the quality control is performed based on the analysis order, When generating an analysis order, the analysis order information selection unit selects the analysis order information regardless of whether the application condition matches the current value.

  Thereby, when accuracy management fails, accuracy management can be re-executed at the next analysis.

  The sample analysis apparatus inquires of the user whether or not to create an analysis order based on the analysis order information before the analysis order information is created based on the analysis order information in the analysis order information application unit. It is preferable to provide an analysis order information application confirmation unit.

  Thereby, when a user does not want, analysis order information can be prevented from being applied when creating an analysis order. Therefore, the analysis can be performed flexibly according to the situation.

  The sample analyzer is preferably configured as follows. That is, this sample analyzer includes a display unit. The display unit can display an analysis order edit screen for editing the analysis order. The display unit displays an analysis order edit screen calling unit for calling the analysis order edit screen when operated by a user. When the analysis order edit screen calling unit is operated, the current value is acquired by the current value acquisition unit. Next, analysis order information whose application condition matches the current value is selected by the analysis order information selection unit. The analysis order information application confirmation unit displays a confirmation message on the display unit as to whether to create an analysis order based on the analysis order information.

  As described above, when the user tries to display the analysis order edit screen in order to edit the analysis order, the analysis order information is automatically selected, and a confirmation message is displayed before the analysis order information is applied. Is done. In this way, analysis order information can be applied simply by performing an operation to edit an analysis order, and no special operation is required to apply the analysis order information, so forget to apply analysis order information. Can be prevented.

  In the sample analyzer, it is preferable that at least one of date, day of the week, time, and number of analyzes can be specified as the application condition.

  As described above, for example, the date, day of the week, time, the number of times of analysis, etc. can be specified as the application condition of the analysis order information. Therefore, when the specific date, day of the week, time, or number of times of analysis is reached, Since it is applied automatically, it is possible to save input and to forget to perform periodic analysis.

  In the sample analyzer, meta-analysis order information is prepared in advance, and it is preferable that the analysis order information can be created based on the meta-analysis order information.

  That is, for routine analysis, it is possible to reduce the labor of creating analysis order information by creating analysis order information based on meta-analysis order information prepared in advance.

  In the sample analyzer, when the analysis order information is created, when the user inputs the number of analyzes within a predetermined period, it is preferable to select and present the optimal analysis order information or meta-analysis order information.

  As described above, when creating analysis order information, the optimum analysis order information or meta-analysis order information is automatically selected and presented, thereby reducing the burden on the user when creating the analysis order information. Can do.

  According to the second aspect of the present invention, the analysis of the sample is performed based on the sample tube setting unit capable of setting a plurality of sample tubes containing the sample and at least one test item corresponding to each sample. An analysis control program for controlling a sample analyzer equipped with an analysis execution unit that executes the following is provided. That is, this analysis control program causes a computer to execute processing including an analysis order setting step, an analysis order information registration step, a current value acquisition step, and an analysis order information selection step. In the analysis order setting step, an analysis order including the position of the sample tube in which the sample is accommodated and the analysis content of the sample is set. In the analysis order information registration step, analysis order information in which the analysis order is associated with an application condition is registered. In the current value acquisition step, a current value corresponding to the application condition is acquired. In the analysis order information selection step, the analysis order information whose application condition matches the current value is selected.

  In this way, by creating analysis order information in advance and applying the analysis order information to create an analysis order, it is possible to reduce the effort that a user manually inputs, Input mistakes can be prevented. Further, by registering the analysis order information in association with the condition, the analysis order information that satisfies the condition can be automatically selected.

  Next, embodiments of the present invention will be described with reference to the drawings. A biochemical automatic analyzer 1 as a sample analyzer according to an embodiment of the present invention includes an analysis control device 2 and a biochemical analyzer main body 3. FIG. 1 shows a block diagram showing a functional configuration of the analysis control device 2 and a schematic plan view of the biochemical analysis device main body 3.

  The analysis control device 2 is configured as a general personal computer (PC), and includes a display unit 4, an operation unit 5, a storage unit 6, a control unit 7, and a communication unit 8.

  The display unit 4 is configured as a display device such as a liquid crystal display. The operation unit 5 includes an input device such as a keyboard and a mouse. The storage unit 6 is configured as a storage device such as a hard disk, but may be an external storage medium such as a CD-ROM. The storage unit 6 stores an analysis control program for controlling analysis by the biochemical automatic analyzer 1. The analysis control program includes an analysis order setting step, an analysis order information registration step, a current value acquisition step, an analysis order information selection step, an analysis order information application step, and an analysis order information application confirmation step. It is.

  The control unit 7 includes a CPU, a ROM, a RAM, and the like. The control unit 7 is configured to be able to communicate with the display unit 4, the operation unit 5, the storage unit 6, the communication unit 8, and the like. The control unit 7 reads and executes the analysis control program stored in the storage unit 6 to thereby execute an analysis order setting unit 10, an analysis order information registration unit 11, a current value acquisition unit 12, an analysis order information selection unit 13, an analysis It is configured to function as the order information application unit 14, the analysis order information application confirmation unit 15, and the like.

  The communication unit 8 is configured as an external communication adapter such as a LAN board, for example. The biochemical analyzer main body 3 is connected to the communication unit 8 via a LAN cable or the like. Thereby, mutual communication of a control signal and data is possible between the analysis control device 2 and the biochemical analysis device body 3.

  The biochemical analyzer main body 3 is used for the purpose of testing various test items such as cholesterol levels using plasma, serum, urine and the like as samples. Briefly, the biochemical analyzer main body 3 causes the sample set in the sample store 21 and the reagent stocked in the reagent store 22 to react in the reaction tank 23 and measures the absorbance of the reaction solution. The unit 24 is configured to measure.

  The flow of analysis using this biochemical automatic analyzer 1 will be briefly described with reference to the flowchart of FIG.

  First, the analysis control device 2 and the biochemical analysis device main body 3 are activated when the user turns on the power or by an automatic wakeup function such as a timer (step S101). Subsequently, the user installs the reagent in the reagent store 22 (step S102) and the sample in the sample store 21 (step S103). Next, when the user operates the analysis control apparatus 2, analysis order registration (order registration) is performed (step S104). The order registration will be described later.

  Subsequently, when the user performs a predetermined analysis start operation, measurement by the biochemical analyzer main body 3 is started in accordance with the registered analysis order (step S105). This measurement result is transmitted to the control unit 7 of the analysis control device 2. In the analysis control device 2, an inspection result is obtained based on the measurement data transmitted from the measurement unit 24, and the inspection result is displayed on the display unit 4 (step S106). When all the measurements are completed, the flow is terminated by turning off the power of the analysis control device 2 and the biochemical analysis device main body 3 or putting it in sleep (step S107).

  Next, the configuration of the biochemical analyzer main body 3 will be described in detail.

  The reaction vessel 23 includes a turntable 25, and a plurality of cells 26 (90 in FIG. 1) are arranged in a ring shape on the turntable 25, which is a reaction container for a sample and a reagent. A measurement unit (analysis execution unit) 24 configured as a photometer is disposed in the vicinity of the turntable 25 and configured to measure the absorbance of the reaction solution in the cell 26. The turntable 25 is configured to be able to rotate intermittently, for example, counterclockwise in FIG. Thus, by rotating the turntable 25 intermittently, the cells 26 whose absorbance is measured by the measurement unit 24 can be sequentially switched. Note that the inside of the reaction tank 23 is maintained at a temperature suitable for advancing the reaction between the specimen and the reagent. Therefore, while waiting for the measurement of the absorbance in the measurement unit 24, the specimen and the reagent can be appropriately reacted inside the cell 26.

  When viewed in the rotation direction of the turntable 25, a cell cleaning unit 27 is disposed on the downstream side of the measurement unit 24 to discard the reaction liquid in the cell 26 that has been measured and clean the cell 26. Has been. As a result, the cell 26 for which measurement has been completed can be reused.

  When viewed in the direction of rotation of the turntable 25, the sample store 21 is disposed further downstream than the cell cleaning unit 27. The sample store 21 includes a rotatable sample tray 28. The sample tray (sample tube setting portion) 28 can be mounted with a plurality of sample tubes 29 (92 samples in FIG. 1) arranged in a ring shape containing samples (patient samples) such as plasma, serum, and urine. A unique position number is assigned to each position of the sample tray 28 that holds each sample tube 29.

  In the vicinity of the sample storage 21, a sample nozzle 30 is arranged for sucking a predetermined amount of sample in the sample tube 29 and dropping it into the cell 26 of the reaction tank 23. A nozzle cleaning unit 31 is disposed in the vicinity of the sample nozzle 30 so that the sample nozzle 30 on which the sample has been dropped can be cleaned with a cleaning liquid.

  When viewed in the direction of rotation of the turntable 25, a reagent store 22 is disposed further downstream than the sample store 21. The reagent store 22 includes a rotatable reagent tray 32. The reagent tray 32 can be loaded with a plurality of reagent bottles 33 containing reagents (60 in FIG. 1) arranged in a ring shape. Further, a reagent nozzle 34 that draws a predetermined amount of the sample in the reagent bottle 33 and drops it in the cell 26 of the reaction tank 23 is disposed in the vicinity of the reagent container 22. Note that the biochemical analyzer main body 3 of the present embodiment includes two reagent nozzles 34 and is configured to be able to cope with a test item of two reagents.

  The state of measuring the sample by the biochemical analyzer main body 3 configured as described above will be briefly described as follows. The cell 26 (empty cell) cleaned by the cell cleaning unit 27 is sent to the downstream side by the rotation of the turntable 25. A predetermined amount of sample is dropped by the sample nozzle 30 into the empty cell 26 that has been sent. The cell 26 into which the specimen has been dropped is sent further downstream, and a predetermined amount of a predetermined reagent is dropped by the reagent nozzle 34. In the cell 26, the sample and the reagent react to form a reaction solution. The cell 26 containing the reaction solution is further sent to the downstream side, and the absorbance is measured by the measurement unit 24. Then, the measurement result by the measurement unit 24 is transmitted to the analysis control device 2.

  Next, main functions of the analysis control device 2 of the present embodiment will be described. The analysis control device 2 mainly includes a function for editing an analysis order, an automatic analysis function for performing an analysis by the biochemical analyzer main body 3 in accordance with the analysis order, and analysis order information for registering analysis order information (described later). And a registration function.

  When the analysis control device 2 is activated, an initial screen as shown in FIG. 3 is displayed on the display unit 4. The left side of FIG. 3 is a function selection unit 40 for selecting a main function of the analysis control apparatus 2, and includes an analysis start button 41 for instructing the start of automatic analysis, and an order edit button ( An analysis order editing screen calling unit) 42, an order information registration button 43 for instructing to call an analysis order information registration function, and the like are displayed. The user can call each function by pressing any one of the buttons 41, 42, and 43 displayed on the function selection unit 40 by appropriately operating the operation unit 5. The right side of FIG. 3 is a function-specific display unit 44 that displays various items according to the buttons 41, 42, and 43 pressed by the user. In the initial screen of FIG. 3, none of the buttons 41, 42, 43 are operated, so nothing is displayed on the function-specific display unit 44.

  Next, analysis order editing in the analysis control apparatus 2 will be described. Here, the analysis order refers to setting data for setting “what analysis content should be analyzed for which sample”.

  When editing the analysis order in the analysis control apparatus 2 of the present embodiment, the user calls the analysis order editing function by pressing the order edit button 42 in FIG. Then, after an analysis order information application confirmation message (described later) is displayed on the display unit, an analysis order edit screen is displayed. The user can appropriately edit the analysis order on this analysis order edit screen.

  FIG. 4 illustrates a state in which the analysis order is being edited in this way. As shown in FIG. 4, on the analysis order edit screen, an analysis order input field 60 and an analysis order save button 61 are displayed.

  In the analysis order input field 60, the contents of the analysis order can be appropriately input. The contents of the analysis order will be briefly described with reference to FIG. The analysis order specifies, for the position number (Pos.) Of the sample tray 28, the type (Type) of the sample set at the position and the inspection item (Method) to be performed on the sample. It is. For example, the analysis order input in the analysis order input field 60 of FIG. 4 will be described. The samples set in the positions No. 1 to No. 3 are standard samples for calibration, and the inspection items Is designated as “inspection item A”. In addition, the sample set in the number 4 position is a control sample for quality control, and the inspection item is designated as “inspection item B”. Samples set at positions No. 5 and later are patient samples to be subjected to normal analysis, and examination items for examinations to be performed on the respective samples are designated. In FIG. 4 and the like, the column for inputting the test item (Method) is one for each sample, but a plurality of test items can be set for one sample.

  The contents of the analysis order input field 60 can be added, deleted, or changed by appropriate operations. In the present embodiment, “patient sample”, “standard sample”, “control sample”, and the like can be designated as sample types. Also, by pressing the analysis order save button 61, the contents of the analysis order entered in the analysis order input field 60 can be saved (set).

  Next, automatic analysis according to the analysis order will be described. By pressing the analysis start button 41, the automatic analysis according to the stored analysis order can be started. The automatic analysis according to the analysis order illustrated in FIG. 4 will be specifically described as follows. That is, when the automatic analysis is started in accordance with the analysis order of FIG. 4, the biochemical analyzer main body 3 reacts the samples set in the positions 1 to 3 with the reagents corresponding to the “test item A”, respectively. Then, the measurement is performed by the measurement unit 24, and the result is transmitted to the analysis control device 2. The analysis control device 2 recreates a calibration curve for “inspection item A” based on the measurement result (calibration).

  Next, the biochemical analyzer main body 3 causes the sample set at the fourth position to react with the reagent corresponding to the “test item B”, and then performs measurement with the measurement unit 24 and analyzes the result. It transmits to the control apparatus 2. In the analysis control device 2, based on the measurement result, the accuracy management for “inspection item B” is performed.

  Next, the measurement unit 24 of the biochemical analyzer main body 3 reacts the specimen set at the fifth and subsequent positions with the reagent corresponding to the test item specified in the analysis order, and then the measurement unit 24 The measurement is performed at 24, and the result is transmitted to the analysis control device 2. In the analysis control device 2, an inspection result for the inspection item is obtained based on the measurement result and a calibration curve that has already been created.

  As described above, the measurement unit 24 is configured to execute the analysis of the specimen based on the examination item corresponding to each specimen. Even if patient specimens, standard specimens, and control specimens are mixed and the examination items of each specimen are different, the analysis contents (specimen type and examination items) should be registered in the analysis order in advance. Thus, it is possible to appropriately analyze.

  Incidentally, in general, analysis order editing as described above is performed each time automatic analysis is performed. This is because the number of patient samples, analysis items, etc. are usually different each time. On the other hand, since calibration and accuracy management are so-called routine analysis, the order registration of standard samples and control samples is the same every time. In the example of FIG. 4, the analysis orders from position numbers 1 to 4 must input the same contents every time calibration of inspection item A and accuracy management of inspection item B are performed.

  Therefore, in the biochemical automatic analyzer 1 of the present embodiment, in order to reduce the burden on the user required to input the analysis order, the typical part of the analysis order (for example, the contents from position numbers 1 to 4 in FIG. 4) ) Is registered in advance, and a new analysis order can be created based on the registered analysis order.

  However, calibration and accuracy management are often performed intermittently (for example, every week) at regular intervals, and are not always executed every time an automatic analysis is performed (each time an analysis order is created). . Therefore, it is not realistic to use a pre-registered analysis order every time. On the other hand, when creating a new analysis order, if the user decides whether or not to use a pre-registered analysis order, the user forgets to apply the pre-registered analysis order. There is a risk that.

  Therefore, in the analysis control program of this embodiment, the analysis order and the application condition can be associated and registered as “analysis order information”. In this way, by registering the analysis order in association with the application condition, the analysis order information is automatically applied when the application condition is satisfied, and the analysis order information is registered when the application condition is not satisfied. It can be made not to apply.

  Hereinafter, registration of analysis order information will be described. When registering analysis order information, the user appropriately operates the operation unit 5 and presses the analysis order information registration button 43. With this as a trigger, the control unit 7 starts the flow of FIG. 5 and causes the display unit 4 to display an analysis order information registration screen. A display example of this analysis order information registration screen is shown in FIG. As shown in FIG. 6, the analysis order information registration screen includes an analysis order information identification information input field 71, an application condition input field 72, an analysis order information content input field 73, an analysis order information storage button 74, Is displayed.

  The user inputs the number and name of newly created analysis order information in the analysis order information identification information input field 71 (step S201).

  The number of the analysis order information is a number for identifying each analysis order information, and is input to the analysis order information number input field 46. The analysis order information number input field 46 is a so-called pull-down list type input field. In this embodiment, numbers from 1 to 10 can be designated. That is, in the biochemical automatic analyzer 1 of this embodiment, up to 10 pieces of analysis order information can be registered. However, the number of pieces of analysis order information that can be registered is not limited to ten. The name of the analysis order information specifies an arbitrary character string so that the user can easily identify each analysis order information, and is input to the name input field 47.

  Subsequently, the user inputs an application condition for the newly created analysis order information in the application condition input field 72 (step S202).

  The application conditions of the analysis order information specify conditions for applying each analysis order information, and different application conditions can be set for each analysis order information. In this embodiment, the date or day of the week and the time or round number can be specified. For example, in the example of FIG. 6, “Mon (Monday)” is input in the day of the week input field 49, and “00: 00 to 11: 59” is input in the time input field 51. In this case, “every Monday from 0:00 to 11:59” is the application condition of the analysis order information.

  On the other hand, in the example of FIG. 7, for example, a date is specified instead of the day of the week, and a round number is specified instead of the time, respectively. In the example of FIG. 7, “1” is entered in the date entry field 55 and “1” is entered in the round number entry field. Here, the round number indicates the cumulative number of analyzes since the biochemical analyzer main body 3 is turned on. Therefore, in the example of FIG. 7, “when the analysis is first performed when the biochemical analyzer is turned on on the first day of every month” is the application condition of the analysis order information.

  Note that which of the date and the day of the week is used as the application condition is specified by the date / day of the week selection field 48. The date / day of the week selection field 48 is a pull-down list type input field, and can select either “Day (date)” or “Week (day of the week)”. When “Week” is selected in the date / day of the week selection field 48, a day of the week input field 49 is displayed on the right side of the date / day of the week selection field 48 as shown in FIG. Thereby, a day of the week can be input as an application condition. On the other hand, when “Day” is selected in the date / day of the week selection field 48, a date input field 55 is displayed on the right side of the date / day of the week selection field 48 as shown in FIG. Thereby, a date can be input as an application condition. In addition, as the date, any one of the dates in the month (1st to 31st) can be designated, and “end of month” or “daily” can also be designated. Further, it may be possible to specify a period (from what day to how many days).

  Similarly, which of the time and the round number is used as the application condition is designated by the time / round number selection column 50. The time / round number selection field 50 is a pull-down list type input field, and can select either “Time (time)” or “Round No. (round number)”. When “Time” is selected in the time / round number selection field 50, a time input field 51 is displayed on the right side of the time / round number selection field 50 as shown in FIG. Thereby, time can be input as application conditions. On the other hand, when “Round No.” is selected in the time / round number selection field 50, a round number input field 56 is displayed on the right side of the time / round number selection field 50 as shown in FIG. Thereby, a round number can be input as an application condition. As the round number, one or more numbers can be designated, and “every time” can be selected.

  In the present embodiment, it is possible to individually specify whether or not to enable automatic application for analysis order information. Specifically, when “Enable” is selected in the automatic applicability selection column 58, automatic application of the analysis order information is enabled, and when “Disable” is selected, automatic application of the analysis order information is disabled. . Thereby, the registered analysis order information can be invalidated individually and temporarily.

  Subsequently, the user inputs the content of the analysis order (analysis content of each position) desired to be associated with the application condition in the analysis order information content input field 73 (step S203). In the analysis order information content input field 73, a fixed part of the analysis order is input. For example, in the example of FIG. 6, since the application condition of this analysis order information is “between 0:00 and 11:59 on every Monday”, analysis of a routine analysis to be performed in the morning every Monday Enter the content (specimen type and test content). Here, “standard sample”, “control sample”, and the like can be selected as the type of sample. In FIG. 6 and the like, the column for inputting a test item (Method) is one for each sample, but a plurality of test items can be set for one sample.

  Finally, when the user presses the analysis order information storage button 74 (step S204), the control unit 7 executes the analysis order information registration step of the analysis control program. At this time, the control unit 7 functions as the analysis order information registration unit 11. Specifically, the analysis order information registration unit 11 inputs information input to the analysis order information identification information input field 71, information input to the application condition input field, and input to the analysis order information content input field 73. The stored contents (analysis order) are associated with each other and stored in the storage unit 6. As described above, the analysis order and the application condition can be registered in association with each other.

  Next, a process for actually creating an analysis order based on the analysis order information registered by the analysis order information registration unit 11 will be described. When a new analysis order is created, the analysis order editing function is called by pressing the order edit button 42. When the analysis order editing function is called, the control unit 7 starts the flow shown in FIG.

  First, the control unit 7 causes the display unit 4 to display an analysis order edit screen (step S301). The analysis order edit screen displayed at this time is shown in FIG. Since an analysis order is newly created at this time, the contents of the analysis order input field 60 are empty as shown in FIG.

  Then, when progressing to step S302, the control part 7 will perform the present value acquisition step of an analysis control program. At this time, the control unit 7 functions as a current value acquisition unit 12. Specifically, the current value acquisition unit 12 acquires a current value corresponding to the application condition of the analysis order information. As described above, in the present embodiment, as the application condition, date, day of the week, time, and round number (number of analyzes) can be specified, so that the current value acquisition unit 12 corresponds to the current value, that is, Get the current date, current day of the week, current time, and current round number. The current date, the current day of the week, and the current time can be obtained by referring to a clock and calendar function inside the PC.

  Then, when progressing to step S303, the control part 7 performs the analysis order information selection step of an analysis control program. At this time, the control unit 7 functions as the analysis order information selection unit 13. Specifically, the analysis order information selection unit 13 searches the registered analysis order information to determine whether there is analysis order information that satisfies the application condition, and such analysis order information. If the information exists, the analysis order information is selected. Here, the application condition is satisfied, specifically, the date or day of the week specified as the application condition of the analysis order information matches the current date or day of the week, and the application condition of the analysis order information Means that the time or round number designated as 合 致 matches the current time or round number. Note that the application condition matches the current value when the value specified as the application condition matches the current value as well as when the application condition is specified as a range (for example, in FIG. Including the case where the current value is included in the range.

  When the analysis order information that satisfies the application condition is not found, the process of the control unit proceeds to step S306. On the other hand, when the analysis order information that satisfies the application condition is found and the analysis order information is selected, the process of the control unit 7 proceeds to step S304. However, even if the application condition is satisfied, if the automatic application is invalidated, the application condition of the analysis order information is regarded as not satisfied, and the process proceeds to step S306.

  In step S304, the control unit 7 executes an analysis order information application confirmation step of the analysis control program. At this time, the control unit 7 functions as the analysis order information application confirmation unit 15. Specifically, the analysis order information application confirmation unit 15 causes the display unit 4 to display an analysis order information application confirmation message as shown in FIG. In the display of the analysis order information application confirmation message, specifically, the analysis order information is applied together with the message “Analysis order information that satisfies the condition was found. Do you want to apply the analysis order information?” A Yes button 45 to specify and a No button 59 to specify that the analysis order information is not applied are displayed.

  Thus, since the user is once inquired whether or not to apply the analysis order information, the analysis order can be flexibly created according to the user's judgment.

  When the Yes button 45 is pressed in step S304, the control unit 7 advances the process to step S305. On the other hand, when the No button 59 is pressed, the control unit advances the process to step S306.

  In step S305, the control unit 7 executes an analysis order information application step of the analysis control program. At this time, the control unit 7 functions as the analysis order information application unit 14. Specifically, the analysis order information application unit 14 creates an analysis order based on the analysis order information selected by the analysis order information selection unit 13. As a more specific process, the analysis order information application unit 14 copies the content of the selected analysis order information (the content input in the analysis order information content input column 73) to the analysis order input column 60. .

  For example, consider a case where an analysis order is created by pressing the order edit button 42 in the morning on Monday. In this case, for example, the application condition of the analysis order information shown in FIG. 6 is “Every Monday from 0:00 to 11:59 (Monday morning)”, so the application condition of the analysis order information is satisfied. Yes. Therefore, after the analysis order information is selected by the analysis order information selection unit 13, an analysis order information application confirmation message is displayed. When the user presses the Yes button 45, the contents registered in the analysis order information (FIG. 6), which is input to the analysis order information content input field 73 on the analysis order information registration screen 6). As a result, as shown in FIG. 10, an analysis order is created based on the contents of the analysis order information shown in FIG.

  As described above, when the application condition of the analysis order information is satisfied, the analysis order is created based on the content of the analysis order information. Therefore, for the routine analysis performed periodically, the labor required for editing the analysis order can be greatly reduced by specifying appropriate application conditions and registering them in the analysis order information. Also, if the application condition is satisfied, the analysis order information is automatically applied, so that the user does not have to manage the schedule for applying the analysis order information. Therefore, analysis schedule management becomes easy.

  Furthermore, in order to create an analysis order, the user must press the order edit button 42 to display the analysis order edit screen. In this embodiment, the analysis order information can be selected simply by pressing the order edit button 42. Applied. Therefore, it is possible to prevent the user from forgetting to apply the analysis order information when creating the analysis order.

  The user can freely edit the analysis order created based on the analysis order information on the analysis order edit screen (S306). For example, the analysis order as shown in FIG. 4 can be formed by sequentially inputting the analysis orders of the patient specimens to be analyzed from the state of FIG. In this way, since the automatically created analysis order can be freely edited by the user, the analysis order can be flexibly created according to the situation.

  In step S305, the analysis order information application unit 14 merely copies the contents of the analysis order information to the analysis order input field 60. Therefore, even if the user edits the analysis order input field 60, There is no worry that the analysis order information will be overwritten. As described above, since the analysis order information itself is not inadvertently overwritten, the contents of the analysis order information can be prevented from being lost due to a user's mistake.

  When the editing of the analysis order is completed, the user presses the analysis order storage button 61 to store the analysis order (S307). Then, using this as a trigger, the control unit 7 executes the analysis order setting step of the analysis control program. At this time, the control unit 7 functions as the analysis order setting unit 10. Specifically, the analysis order setting unit 10 stores (sets) the contents (the position of each sample and the analysis contents of the sample) input in the analysis order input field 60 in the storage unit 6. Thus, the analysis order editing is completed. When the analysis order is set as described above, the sample can be analyzed based on the analysis order.

  If analysis order information that satisfies the application condition is not found in S303, or if the No button 59 is pressed in S304, editing of the analysis order is started without applying the analysis order information. In this case, the user inputs an analysis order from a state where nothing is input in the analysis order input field 60 as shown in FIG.

  As described above, the biochemical automatic analyzer 1 according to the present embodiment includes the sample tray 28 on which a plurality of sample tubes 29 in which samples are accommodated, and at least one test item corresponding to each sample. And a measurement unit 24 that executes the analysis of the specimen, and is configured as follows. That is, the biochemical automatic analyzer 1 includes an analysis order setting unit 10, an analysis order information registration unit 11, a current value acquisition unit 12, and an analysis order information selection unit 13. The analysis order setting unit 10 sets an analysis order including the position of the sample tube 29 in which the sample is accommodated and the analysis content of the sample. The analysis order information registration unit 11 registers analysis order information in which an analysis order is associated with an application condition. The current value acquisition unit 12 acquires a current value corresponding to the application condition. The analysis order information selection unit 13 selects analysis order information whose application condition matches the current value.

  Also, the analysis control program of this embodiment includes an analysis order setting step (step S307), an analysis order information registration step (step S204), a current value acquisition step (step S302), and an analysis order information selection step (step S303). ) Are executed by the computer. In the analysis order setting step, an analysis order including the position of the sample tube 29 in which the sample is accommodated and the analysis content of the sample is set. In the analysis order information registration step, the analysis order information in which the analysis order is associated with the application condition is registered. In the current value acquisition step, a current value corresponding to the application condition is acquired. In the analysis order information selection step, analysis order information whose application condition matches the current value is selected.

  In this way, by creating analysis order information in advance and applying the analysis order information to create an analysis order, it is possible to reduce the effort that a user manually inputs, Input mistakes can be prevented. Further, by registering the analysis order information in association with the condition, the analysis order information that satisfies the condition can be automatically selected.

  The biochemical automatic analyzer 1 according to the present embodiment includes an analysis order information application unit 14 that creates an analysis order based on the analysis order information selected by the analysis order information selection unit 13.

  As a result, the analysis order information that satisfies the condition is automatically applied to create the analysis order, so that an appropriate analysis order can be created.

  Moreover, the biochemical automatic analyzer 1 of this embodiment is configured as follows. That is, the analysis content of the sample includes at least information indicating the type of the sample. As the type of the sample, at least one of a standard sample for calibration and a control sample for accuracy control can be designated.

  That is, since calibration and accuracy management are routine analysis, registration of the sample for calibration and accuracy management in the analysis order can be saved by registering in the analysis order information. For example, if the analysis order information is registered by designating the date and time when calibration and accuracy management are performed as application conditions, forgetting to perform calibration and accuracy management can be prevented.

  In addition, the biochemical automatic analyzer 1 of the present embodiment creates an analysis order based on the analysis order information before the analysis order information application unit 14 generates the analysis order based on the analysis order information. An analysis order information application confirmation unit 15 that inquires the user whether or not to perform the analysis is provided.

  Thereby, when a user does not want, analysis order information can be prevented from being applied when creating an analysis order. Therefore, the analysis can be performed flexibly according to the situation.

  Moreover, the biochemical automatic analyzer 1 of this embodiment is configured as follows. That is, the biochemical automatic analyzer 1 includes a display unit 4. The display unit 4 can display an analysis order edit screen for editing an analysis order. The display unit 4 displays an order edit button 42 for calling the analysis order edit screen when operated by the user. When the order edit button 42 is operated, a current value corresponding to the application condition is acquired by the current value acquisition unit 12. Next, the analysis order information selection unit 13 selects analysis order information whose application condition matches the current value. Then, the analysis order information application confirmation unit 15 displays a confirmation message on the display unit 4 as to whether or not to create an analysis order based on the analysis order information.

  As a result, when the user tries to display the analysis order edit screen in order to edit the analysis order, the analysis order information is automatically selected and a confirmation message is displayed before the analysis order information is applied. The In this way, analysis order information can be applied simply by performing an operation to edit an analysis order, and no special operation is required to apply the analysis order information, so forget to apply analysis order information. Can be prevented.

  In the biochemical automatic analyzer 1 of the present embodiment, the application condition can specify a date, day of the week, time, and round number.

  As described above, for example, the date, day of the week, time, the number of times of analysis, etc. can be specified as the application condition of the analysis order information. Since it is applied automatically, it is possible to save input and to forget to perform periodic analysis.

  Next, a modified example of the present invention will be described. As described above, how often the calibration and accuracy management are performed depends on the judgment of the user. Therefore, it is realistic that the manufacturer of the biochemical automatic analyzer 1 prepares analysis order information in advance. is not. However, since calibration and accuracy management are routine operations, it is considered that information that is the basis of analysis order information, that is, meta-analysis order information can be prepared.

  For example, the manufacturer prepares in advance meta-analysis order information in which only the sample type (Type) field in the analysis order information content input field 73 shown in FIG. 6 is entered, and the user fills in the test item (Method) field. Thus, the analysis order information can be completed. Note that the meta-analysis order information is prepared in advance includes not only the case where the meta-analysis order information is prepared in advance, but also the case where the meta-analysis order information is automatically created according to a pre-prepared algorithm.

  Further, when the analysis order information is registered based on the meta-analysis order information, it is more preferable that the optimum meta-analysis order information can be automatically selected and presented to the user. For example, when the user presses the analysis order information registration button 43 to newly register analysis order information, the control unit 7 causes the display unit 4 to display an input field for inputting the number of analyzes within a predetermined period. The user inputs how much the analysis using the analysis order information to be registered is to be executed within a predetermined period. Then, the control unit 7 determines calibration and accuracy management to be included in the new analysis order information from the designated number of analyzes, and presents appropriate meta-analysis order information to the user. At this time, if analysis order information already created exists and it can be determined that it is appropriate to create new analysis order information based on the existing analysis order information, the meta-analysis order information Instead, the ready-made analysis order information may be presented to the user.

  As described above, in the biochemical automatic analyzer 1 of this modification, meta-analysis order information is prepared in advance, and the analysis order information can be created based on the meta-analysis order information. is there.

  That is, for routine analysis, it is possible to reduce the labor of creating analysis order information by creating analysis order information based on meta-analysis order information prepared in advance.

  Further, in the biochemical automatic analyzer 1 of the present modification, when the analysis order information is created, when the user inputs the number of analyzes within a predetermined period, the optimum analysis order information or meta-analysis order information is selected. It is configured to present.

  As described above, when creating analysis order information, the optimum analysis order information or meta-analysis order information is automatically selected and presented, thereby reducing the burden on the user when creating the analysis order information. Can do.

  Next, another modification of the above embodiment will be described. Calibration and quality control may fail. Here, the failure of calibration means a case where the created calibration curve formula is greatly different from the expected formula. Further, the failure of accuracy control means a case where the result of analyzing the control sample exceeds a predetermined allowable range. If such a failure occurs, it is necessary to re-execute calibration and accuracy management.

  Therefore, in this modification, an analysis order is created by applying analysis order information in which standard samples for calibration and control samples for quality control are registered, and analysis is performed according to the analysis order. When the calibration or accuracy management fails, the analysis order information is applied to the next analysis regardless of whether the application condition is satisfied. That is, the failed calibration or accuracy management is redone regardless of whether the application conditions of the analysis order information are satisfied. As a result, it is possible to reduce the trouble that the user has to input the analysis order when performing calibration and accuracy management again.

  As explained above, the biochemical automatic analyzer 1 of the present modification is configured as follows. That is, when an analysis order is created based on analysis order information including information on the sample designated as the standard sample and calibration is performed based on the analysis order, if the calibration fails, the next time When generating an analysis order, the analysis order information selection unit 13 selects the analysis order information regardless of whether the application condition matches the current value.

  Thereby, when calibration fails, calibration can be re-executed at the next analysis.

  Moreover, the biochemical automatic analyzer 1 of this modification is comprised as follows. That is, when an analysis order is created based on the analysis order information including the information of the sample designated as the control sample, and the quality control is performed based on the analysis order, When creating an analysis order, the analysis order information selection unit 13 selects the analysis order information regardless of whether the application condition matches the current value.

  Thereby, when accuracy management fails, accuracy management can be re-executed at the next analysis.

  The preferred embodiments and modifications of the present invention have been described above, but the above configuration can be modified as follows, for example.

  In the above embodiment, the sample analyzer is described as an automatic biochemical analyzer. However, the configuration of the present invention is not limited to this, and can also be applied to other types of sample analyzers such as an immune analyzer.

  The analysis control device is a general PC, but may be a dedicated device.

  Further, the biochemical analyzer main body 3 and the analysis control device 2 may be integrated.

  In the above description, the information that can be input to the analysis order is the sample type and analysis item of each position. However, the present invention is not limited to this, and various information related to the sample can be input. For example, a serial number or a control sample serial number may be input.

  Although three types of specimens, a patient specimen, a standard specimen, and a control specimen, are exemplified as the specimen types, the specimen types are not limited to this. For example, a blank may be designated. In the above embodiment, the standard sample for calibration and the control sample for quality control are listed as examples of the sample to be registered in the analysis order information. However, other samples may be registered in the analysis order information. Is possible. In other words, for routine analysis that needs to be performed regularly, even if it is not calibration or accuracy control, the user creates an analysis order by registering the sample related to the analysis in the analysis order information. Can be reduced.

  The application conditions of the analysis order information are not limited to the date, day of the week, time, round number, etc., and other appropriate conditions can be designated.

  In the above embodiment, the analysis order information is assumed to be performed on the analysis order information registration screen, but is not limited to this configuration. For example, as shown in FIG. 4, after an analysis order is input on the analysis order edit screen, the analysis order may be registered as it is as analysis order information.
