Driving means for rotating the wheel about the vertical line passing therethrough (not shown). The inside of each container holding part is kept at a constant temperature. For example, the inside of the reagent container holding unit 13 is set to a temperature lower than room temperature in order to suppress deterioration and denaturation of the reagent. Further, the inside of the reaction container holding unit 14 is set to a temperature that is comparable to the human body temperature. When performing biochemical analysis, since two types of reagents are often used for one specimen, the reagent container holding unit 13 for the first reagent and the reagent container holding unit for the second reagent 13 may be provided separately, and a reagent dispensing unit 16 corresponding to each reagent container holding unit 13 may be provided separately.

And a search unit 232 for performing. The calculation unit 231 performs a calculation for converting the absorbance measured by the photometry unit 18 into a concentration by using a calibration curve included in the calibration data stored in the storage unit 24 as a specific analysis calculation.

  Next, a calibration curve display method of the automatic analyzer according to the first embodiment will be described. The user causes the display unit 22 to display a calibration curve display screen for displaying a calibration curve by performing a predetermined operation input from the input unit 21. FIG. 2 is a diagram illustrating a display example of an initial state of the calibration curve display screen on the display unit 22. The calibration curve display screen 41 shown in the figure includes a graph 42 in which the horizontal axis indicates the concentration value and the vertical axis indicates the photometric value (absorbance), a data selection button 43 for selecting the content to be displayed in the graph 42, and the calibration curve display screen. A cancel button 44 for canceling the display of 41 is displayed. In the initial state shown in FIG. 2, the calibration curve is not yet displayed on the graph 42.

  Subsequently, when the user operates a mouse that forms part of the input unit 21 to align the mouse pointer P displayed on the display unit 22 with the data selection button 43 and then presses a predetermined button on the mouse, the display is displayed. The unit 22 displays a data selection screen. At this time, the display unit 22 may further display the data selection screen while the calibration curve display screen 41 remains open. Note that the processing selection operation described here can also be realized using a pointing device (trackpad, trackball, etc.) other than a mouse.

  Thereafter, after operating a pointing device such as a mouse so that the mouse pointer P is set to a button provided on the screen, an operation of selecting a process by a predetermined button or the like included in the pointing device is simply clicked on the button. ".

  FIG. 3 is a diagram illustrating a display example of the data selection screen on the display unit 22. In the data selection screen 51 shown in the figure, the user can select up to two pieces of calibration data (basic data and comparison data) by operating the input unit 21.

  The basic data is calibration data corresponding to a calibration curve that is a target of abnormality determination. In FIG. 3, calibration data having an analysis date of “November 30, 2006, 11:45” is selected as basic data. When making this selection, the user clicks a selection button 53 provided on the right side of the analysis date / time display unit 52 for displaying the analysis date / time of the basic data, and selects from a plurality of candidates displayed on the analysis date / time display unit 52. Select the desired analysis date and time.

  The comparison data is calibration data selected for comparison with the basic data. On the data selection screen 51, a box 54 is provided in the left area where "comparison data" is displayed. When the user clicks on the box 54, a check is displayed inside the box 54, and display of comparison data is selected. Subsequently, the user clicks a selection button 56 provided on the right side of the analysis date / time display unit 55 for displaying the analysis date / time of the comparison data, and a plurality of candidates (in FIG. 3) displayed on the analysis date / time display unit 55. Click the desired analysis date / time from among the 5 candidates).

  When the user completes the data selection process described above, the user clicks an OK button 57. On the other hand, when the user cancels the data selection process, the cancel button 58 is clicked.

  Thereafter, the search unit 232 of the control unit 23 searches the storage unit 24 for the calibration data selected by the data selection process described above. FIG. 4 is a diagram illustrating a display example of a calibration curve corresponding to the calibration data obtained by the search by the search unit 232. The graph 42 shown in the figure displays two different calibration curves in an overlapping manner. Specifically, a calibration curve C1 indicated by a solid line corresponds to basic data, and a calibration curve C2 indicated by a broken line corresponds to comparison data. The two calibration curves C1 and C2 have the same coordinate system. Also, the plot point P1 (displayed by a square) of the calibration curve C1 and the plot point P2 (displayed by a circle) of the calibration curve C2 indicate the respective calibration points (in FIG. 4, the calibration points of each calibration curve). Is three). When a plurality of different calibration curves are displayed in an overlapping manner, the color may be changed for each calibration curve.

  Here, the advantage when the user performs the abnormality determination of the calibration curve using the graph 42 will be described in comparison with the case where the abnormality determination of the calibration curve using the graph 81 of the conventional method shown in FIG. 8 is performed. First, when a user performs an abnormality determination of a calibration curve using the graph 81, it is possible to confirm a change over time for each calibration point, but it is difficult to compare the shapes of calibration curves with different analysis dates and times. It is. In particular, in the case of an analysis item in which the calibration curve forms a curve, it is almost impossible for the user to compare the shapes of different calibration curves using only the polygonal lines L1 to L3 of the graph 81. On the other hand, when the user determines the abnormality of the calibration curve using the graph 42, the shape of the calibration curve C1 and the calibration curve C2 that form a curve can be easily compared. Therefore, the user can accurately determine the abnormality of the calibration curve by using the graph 42.

  According to the first embodiment of the present invention described above, a plurality of different calibration curves for the same analysis item created by performing calibration analysis are displayed on one screen so that the same user can be obtained. Therefore, it is possible to easily confirm the change over time in the shape of the calibration curve for the analysis item, and to accurately determine the abnormality of the calibration curve.

  Further, according to the first embodiment, the user can display the calibration curve by selecting the calibration curve to be displayed on the display unit, searching the calibration data in the storage unit according to the selection input, and displaying the calibration data. The calibration curve to be performed can be arbitrarily selected.

  Furthermore, according to the first embodiment, since the user can easily compare the shape of the calibration curve on the same screen, the burden on determining the abnormality of the calibration data is greatly reduced. . As a result, the accuracy of the calibration curve abnormality determination by the user is improved, and as a result, the reliability of the calibration data in the automatic analyzer can be further improved.

  The number of calibration curves displayed on the display unit 22 may be three or more. In other words, in the first embodiment, two or more comparison data may be selected for the basic data.

  When selecting calibration data, select not only the analysis date but also information on reagent lots and reagent bottles used in calibration analysis, or information on lots of calibration samples (calibrator lots). It is also possible to add it as a condition.

(Embodiment 2)
The second embodiment of the present invention is characterized in that the automatic analyzer automatically displays a plurality of calibration curves in accordance with preset display conditions. The configuration of the automatic analyzer according to the second embodiment is substantially the same as the configuration of the automatic analyzer 1 according to the first embodiment (see FIG. 1), but the search process of the search unit 232 of the control unit 23. The contents stored in the storage unit 24 are different from those in the first embodiment.

  FIG. 5 is a flowchart showing an outline of processing of the calibration curve display method of the automatic analyzer according to the second embodiment. FIG. 5 shows an outline of processing performed after the user selects and inputs an analysis item to be displayed from the input unit 21.

  In FIG. 5, the search unit 232 of the control unit 23 searches the storage unit 24 for calibration data of the specified analysis item based on a predetermined search condition (step S1). The search conditions at this time differ depending on the analysis item. Therefore, the storage unit 24 stores analysis items and search conditions in association with each other. Further, the search unit 232 reads a search condition corresponding to the analysis item from the storage unit 24 and searches for calibration data based on the read search condition.

  Here, the search condition will be described. For example, in the case of an analysis item that requires a calibration curve for each reagent lot, the calibration curve for the same reagent lot should be displayed in an overlapping manner. Therefore, it is preferable that the search condition for the analytical curve for such an analysis item is “same reagent lot”. On the other hand, in the case of an analysis item that requires a calibration curve for each reagent bottle, since the calibration curve for the same reagent bottle should be displayed in an overlapping manner, the search condition is preferably “same reagent bottle”. In the case of analysis items that do not require the creation of a calibration curve according to reagent lots or reagent bottles, it is not necessary to impose special search conditions. In addition, “same calibrator lot” can be adopted as a search condition that can be paralleled with the information related to the reagent.

When calibration data of the selected analysis item is obtained as a result of the search by the search unit 232 in step S < _b > 1 (step S < _b > 2, Yes), the number of acquired calibration data nc is displayed in an overlapping manner on the display unit 22. If the number of calibration curves is N or less (step S3, Yes), the display unit 22 displays all calibration curves corresponding to the acquired calibration data (step S4). On the other hand, the number n _c of the obtained calibration data is, The more than the number N of the calibration curve to be displayed superimposed on the display unit 22 (step S3, No), the calibration data display unit 22 in accordance with a predetermined display condition The calibration curve corresponding to the remaining calibration data is displayed (step S5). The “display conditions” here include conditions corresponding to the search conditions in the search unit 232, the number N of calibration curves to be displayed in an overlapping manner, conditions for selecting calibration data, and the like. Among these, as a condition for selecting calibration data, for example, a condition of selecting from the latest calibration data in the newest order can be adopted.

  As a result of the search by the search unit 232 in step S1, if the calibration data of the selected analysis item is not obtained (No in step S2), the display unit 22 displays the calibration curve display screen 41 on the graph 42. "No calibration data" is displayed (step S6), and a series of processing ends.

  According to the second embodiment of the present invention described above, a plurality of different calibration curves for the same analysis item created by performing calibration analysis are displayed on one screen so that the same user can be obtained. Therefore, it is possible to easily confirm the change over time in the shape of the calibration curve for the analysis item, and to accurately determine the abnormality of the calibration curve.

  Further, according to the second embodiment, the calibration data in the storage unit is searched based on the display conditions of the calibration curve determined according to the analysis item, and a plurality of calibration curves obtained by this search are displayed. Thus, an optimal calibration curve can be displayed for each analysis item.

  Furthermore, according to the second embodiment, as in the first embodiment, the burden on the user when determining abnormality of the calibration data is greatly reduced. As a result, the calibration data in the automatic analyzer can be reduced. Reliability can be further improved.

(Modification of Embodiment 2)
One modification of the second embodiment has a configuration in which a user can set display conditions on the display unit 22. FIG. 6 is a diagram illustrating an example of a display condition setting screen displayed on the display unit 22 in this modification. In the display condition setting screen 61 shown in the figure, the user clicks the selection button 63 provided on the right side of the analysis item display unit 62 for displaying the analysis items, and the plurality of items displayed on the analysis item display unit 62 are displayed. A desired analysis item is selected from the candidates. In FIG. 6, albumin (ALB) is selected as the analysis item.

  On the display condition setting screen 61, four conditions of “same reagent lot”, “same reagent bottle”, “same calibrator lot”, and “not specified” are displayed as display conditions relating to the analysis item. The user selects a display condition related to the analysis item by clicking a box corresponding to a desired display condition among the boxes 64a to 64d provided on the left side of each display condition description place. In FIG. 6, “same reagent lot” is selected as the display condition for the analysis item.

  The above four conditions correspond to the calibration curve search conditions in the search unit 232. In this sense, in this modification, the search condition of the search unit 232 is also changed when the user sets the display condition.

  On the display condition setting screen 61, when the user sets the number N of calibration curves to be displayed on the display unit 22, the selection button 66 provided on the right side of the calibration curve number display unit 65 is clicked. Then, a desired number is selected from a plurality of candidates displayed on the calibration curve number display unit 65. In FIG. 6, “3” is selected as the value of N.

  When the user completes the display condition setting process described above, an OK button 67 is clicked. On the other hand, when the user cancels the display condition setting process, the cancel button 68 is clicked.

Note that the default value of the display condition corresponding to the analysis item is stored in the storage unit 24 in advance, and when the user selects the desired analysis item, the default value among the boxes 64a to 64d of the display condition setting screen 61 is displayed. A check may be automatically added to a box corresponding to. The setting, the number n _c of the calibration data is, if it exceeds the number N of the calibration curve to be displayed superimposed on the display unit 22 a calibration curve selection condition (n _c> N), the user from the input unit 21 You may enable it to input.
