[Operation of sample analyzer]
Next, the operation of the sample analyzer 1 according to this embodiment will be described. In the sample analyzer 1 according to the present embodiment, date processing can be executed. The date processing is processing for determining the time at which one day starts in the sample analyzer 1. The information processing unit 4 has an internal clock and can acquire the current time. In date processing, what is the actual time by the internal clock (local time of the information processing unit 4; generally, it is set to Japan standard time in Japan) (for example, 2:30 am). The user can set whether to start the day. The “current day” described below is the current day determined according to the date starting from the beginning determined by the user through date processing. For example, when 2:30 am is set as the first day of the day, when the actual time is 3:00 am on July 29, 2011, July 29, 2011 is set as the current day, When the actual time is 1:00 am on July 29, 2011, July 28, 2011 is set as the current day.

  11A and 11B are flowcharts showing the procedure of the analysis preparation operation of the sample analyzer 1. First, the operation of the measurement unit 2 will be described. When the sample analyzer 1 is turned on, the reagent setting unit 16 of the measurement unit 2 is set with the R1 / R3 reagent and the R2 reagent used on the day. When the power of the measurement unit 2 is turned on by the user, the CPU 201 of the measurement unit 2 performs initialization processing of each mechanism unit of the measurement unit 2 (step S101). By this processing, each mechanism unit such as the sample dispensing arm and the reagent dispensing arm is moved to the initial position for the measurement operation. Next, the CPU 201 causes the antennas 162b and 163b to read out the reagent management information from the RFID tag of the R1 / R3 reagent container and the RFID tag of the R2 reagent container installed in the reagent installing unit 16 (steps). S102). Further, the CPU 201 transmits the acquired reagent management information to the information processing unit 4 (step S103), and ends the process.

  Next, the operation of the information processing unit will be described. When the information processing unit 4 is powered on, the CPU 401 of the information processing unit 4 initializes hardware and software (step S201), and whether or not the reagent management information transmitted from the measurement unit 2 has been received. Is determined (step S202). If reagent management information has not been received (NO in step S202), CPU 401 repeatedly executes the process of step S202 and waits until reagent management information is received. When the information processing unit 4 receives the reagent management information (YES in step S202), the CPU 401 registers the reagent management information in the reagent management database DB100 (step S203).

  Next, the CPU 401 displays a logon screen on the display unit 420 (step S204). The logon screen is provided with an input box for inputting a user name (user ID) and a password. The user inputs a user name and password in these input boxes and instructs execution of the logon process. The CPU 401 determines whether or not a logon process execution instruction has been accepted (step S205). If the logon process execution instruction has not been accepted (NO in step S205), the CPU 401 repeats the process of step S205. Wait for execution instructions. When CPU 401 receives an instruction to execute logon processing (YES in step S205), CPU 401 executes logon processing (step S206). In the logon process, logon authentication is performed in which the user name and password entered on the logon screen are compared with the user name and password registered in the user database DB600. When the logon authentication fails (NO in step S207), the CPU 401 displays a logon screen including a message notifying the user that the logon authentication has failed on the display unit 420 (step S204).

  When the logon authentication is successful (YES in step S207), the CPU 401 acquires the setting value of the logged-on user from the user database DB 600, and an initial screen displayed as a screen that can be operated by the user for the first time immediately after the logon is a menu. It is determined whether the screen is set or the maintenance status confirmation screen is set (step S208). The initial screen setting value is the default value on the maintenance status confirmation screen.

  When the initial screen is set as the menu screen (“menu screen” in step S208), the CPU 401 displays the menu screen on the display unit 420 (step S209) and ends the activation process.

  FIG. 12 is a diagram showing the configuration of the menu screen. The menu screen D100 is provided with a toolbar area A110 in which a toolbar is displayed, and a main area A130 in which a plurality of icons for moving to another screen are displayed. The toolbar area A110 and the main area A130 are provided not only on the menu screen D100 but also on other screens of the information processing unit 4.

  Here, the “icon” refers to an image that is assigned a specific function and is designed to symbolically represent the function, and includes an image displayed in a window.

  The toolbar area A110 is provided at the top of the screen. A main area A130 is provided below the toolbar area A110. The main area A130 is an area larger than the toolbar area A110, and displays the main contents of the screen. In the main area A130 of the menu screen D100, icons are arranged over three lines. In the first line (uppermost line), a “logoff” icon C131 for a user who logs on to the sample analyzer 1 to log off, a “version information” icon C132 for confirming the version of the computer program 404a, a sample A “setting” icon C133 for representing a setting screen used for setting of the analyzer 1 and a “patient information” icon C134 for registering patient information in the patient information database provided on the hard disk 404 are provided. ing. In the second row, an “error history” icon C135 for displaying an error history of the sample analyzer 1, a “reagent history” icon C136 for displaying a history of reagents used in the sample analyzer 1, a sample analysis A “consumable history” icon C137 for displaying the history of consumables used in the apparatus 1, an “operation history” icon C138 for displaying an operation history by the user of the sample analyzer 1, and the sample analyzer 1 A “component replacement history” icon C139 for displaying a component replacement history is provided. In the third line, a “service call” icon C140 for contacting the maintenance service provider of the sample analyzer 1 and an “instruction manual” icon C141 for displaying an instruction manual are provided. These icons C131 to C141 can be selected by a mouse click operation. When any of these icons C131 to C141 is selected by a mouse click operation, a corresponding command is executed.

  Returning to the description of the activation process of the sample analyzer 1. When the initial screen is set as the maintenance status confirmation screen (“maintenance status confirmation screen” in step S208), the CPU 401 executes a reagent information acquisition process (step S210). FIG. 13 is a flowchart showing the procedure of the reagent information acquisition process. In the reagent information acquisition process, first, the CPU 401 sets the target date (start-up process) for each reagent installed in the reagent installation unit 16 of the measurement unit 2 based on the reagent usage history stored in the reagent usage history database DB200. Then, the usage prediction process for “current day”) is executed (step S301). In this use prediction process, for example, the CPU 401 calculates, for each measurement item, an average value per day of reagent usage within a certain period in the past (for example, three months immediately before the target date). Let each be the estimated amount of reagent used for each measurement item on the target day. Next, the CPU 401 selects one of the measurement items as a target measurement item (step S302). Next, the CPU 401 compares the remaining amount of the reagent of the target measurement item installed in the reagent installation unit 16 with the predicted usage amount of the target day of the reagent of the target measurement item (step S303). If the reagent remaining amount is equal to or greater than the predicted usage amount (YES in step S303), the CPU 401 sets the display color of the excess / deficiency amount of the reagent of the target measurement item to the first color (black) (step S304), and processing To step S306. On the other hand, when the reagent remaining amount is less than the predicted usage amount (NO in step S303), the display color of the excess / deficiency amount of the reagent of the target measurement item is set to the second color (orange) (step S305), and the process is performed. Move to step S306.

  Next, the CPU 401 calculates the difference between the remaining amount of the reagent of the target measurement item and the predicted usage amount, and acquires the excess / deficiency amount of the reagent of the target measurement item (step S306). This excess / deficiency is 0 or a positive value when the remaining amount of the reagent is greater than or equal to the predicted use amount, that is, when it is estimated that it is not necessary to replace the reagent during the target day even if the sample measurement is performed. When the remaining amount is less than the predicted use amount, that is, when it is estimated that it is necessary to replace the reagent during the target day when the sample measurement is performed, the negative value is obtained.

  Next, the CPU 401 determines whether or not all measurement items have been selected as target measurement items (step S307). If there is a measurement item that has not been selected as the target measurement item (NO in step S307), The process moves to step S302, and one of the unselected measurement items is selected as the target measurement item. On the other hand, when all the measurement items are selected as the target measurement items (YES in step S307), the CPU 401 returns the process to the call address of the reagent information acquisition process in the activation process.

  Next, the CPU 401 executes maintenance information acquisition processing (step S211). FIG. 14 is a flowchart illustrating a procedure of maintenance information acquisition processing. In the maintenance information acquisition process, first, the CPU 401 records a record of an implementation schedule or a record date of a target date, that is, maintenance work information scheduled to be performed on the day (hereinafter referred to as “maintenance work schedule information”), into a maintenance schedule record database. Extracted from the DB 500 (step S401). Next, the CPU 401 determines whether there is selectable maintenance work schedule information (step S402). In the process of step S402, the maintenance work schedule information already selected in step S403 described later is not included in the selectable maintenance work schedule information. That is, only unselected maintenance work schedule information can be selected. Therefore, after all the maintenance work schedule information extracted in step S401 is selected, there is no selectable maintenance work schedule information. If no maintenance work schedule information is extracted in step S401, that is, if there is no maintenance work scheduled to be performed on the day, there is no selectable maintenance work schedule information.

  If there is selectable maintenance work schedule information in step S402 (YES in step S402), the CPU 401 selects one of the unselected maintenance work schedule information (step S403). Next, the CPU 401 determines whether or not the user name of the practitioner is included in the selected maintenance work schedule information (step S404). If the user name of the practitioner is included in step S404 (YES in step S404), it means that the maintenance work is being performed. Therefore, in this case, the CPU 401 stores the execution information indicating that it has been executed in association with the selected maintenance work schedule information in the RAM 403 (step S405), and moves the process to step S402. On the other hand, if the user name of the practitioner is not included in step S404 (NO in step S404), the CPU 401 proceeds to step S402 as it is.

  In step S402, if there is no selectable maintenance work schedule information (NO in step S402), the CPU 401 returns the process to the call address of the maintenance information acquisition process in the start process.

  Next, the CPU 401 acquires bulletin board information (poster's user name and message) from the bulletin board database DB 700 (step S212). Further, the CPU 401 obtains output signals from the remaining amount sensors 10a and 13a, the capacity sensor 910a, the liquid level sensors 920a, 930a, 940a, and 950a, and determines whether the remaining amount of the cuvette is equal to or larger than a predetermined amount Whether the remaining amount is more than a predetermined amount, the number of times the filter paper is used is less than a predetermined value, the amount of waste in the waste container 910 is less than a predetermined amount, the amount of waste liquid in the drainage container 920 is less than a predetermined amount, It is determined whether the remaining amount is a predetermined amount or more, the remaining amount of the B / F separation cleaning liquid is a predetermined amount or more, the remaining amount of the probe washer is a predetermined amount or more, and the remaining amount of the R4 / R5 reagent is a predetermined amount or more. (Step S215). Further, the CPU 401 displays a maintenance status confirmation screen on the display unit 420 based on the information acquired in steps S210 to S212 (step S213), and ends the activation process. With these activation processes, the measurement preparation operation ends, and the sample analyzer 1 enters a measurement standby state in which the sample measurement can be performed.

  FIG. 15 is a diagram showing the configuration of the maintenance status confirmation screen. In the toolbar area A110 of the maintenance status confirmation screen D200, the same icon group as the toolbar area A110 of the menu screen D100 is displayed. The main area A130 of the maintenance status confirmation screen D200 has a content area A231 and a menu area A232 provided on the right side of the content area A231.

  The content area A231 is divided into four areas A233 to A236. More specifically, the content area A231 includes a maintenance work display area A233 provided in the upper left portion of the content area A231, a bulletin board area A234 provided below the maintenance work display area A233, a maintenance work display area A233, and It has a reagent information display area A235 provided on the right side of the bulletin board area A234, and a consumable information display area A236 provided below the content area A231.

  In addition, a target date designating unit C237 for designating a target date is provided in the upper right part of the content area A231. The target date designating part C237 is composed of an input box and two buttons. This input box is used to enter the date of the target date. The designated target date is displayed in this input box. The two buttons are arranged side by side, and the left button displays a triangle with one vertex directed to the left. The right button displays a triangle with one vertex pointing to the right. The left button is a button for returning the date displayed in the input box by one day, and the right button is a button for advancing the date displayed in the input box by one day. The user can specify the target date by using such an input box and two buttons. Note that the default value of the target day is the current day, and in the above-described activation process, the maintenance status confirmation screen D200 is displayed with the current day as the target day.

  In the maintenance work display area A233, maintenance work to be performed on the target day is displayed. That is, the maintenance work schedule information acquired in the maintenance information acquisition process of step S213 described above is displayed in the maintenance work display area A233. The maintenance work display area A233 will be described in more detail. The maintenance work display area A233 displays a list of item names of maintenance work (ToDo) that the user should perform on the target day. This maintenance work information can be set by the user on another setting screen. A check mark icon C238 is displayed next to the work already executed. That is, the check mark icon C238 is displayed beside the maintenance work schedule information stored in the RAM 403 in association with the execution information in step S405. Further, on the right side of the maintenance item name, the name of the user who executed the maintenance work (“automatic” when automatically executed by the sample analyzer 1) is displayed, and further on the right side, the maintenance item name is displayed. The work execution time is displayed. For maintenance work that has not yet been executed, the user name and execution time are not displayed. As a result, the user can easily confirm the maintenance work to be performed on the target day, which work has already been completed, who has performed the work, and when the work has been performed. .

  Above the maintenance work display area A233, a button B239 on which a character string “maintenance” is displayed is provided. The button B239 can be selected by a mouse click operation, and a command for displaying a user maintenance screen to be described later is issued when the button B239 is selected.

  In the bulletin board area A234, communication items from other users are displayed in a list format. That is, the bulletin board information acquired in step S214 described above is displayed in the bulletin board area A234. This contact item can be input by the user on another screen (bulletin board registration screen), and the bulletin board information including the input contact item is registered in the bulletin board database DB700. Further, on the right side of the contact item, the user name and input time of the user who has input the contact item are displayed. Thereby, even if a user does not talk directly, communication between users can be taken easily. In addition, it is possible to easily know who and what communication items have been input by simply checking the contents of the bulletin board area A234.

  A button B240 on which a pencil mark is displayed is provided between the maintenance work display area A233 and the bulletin board area A234. This button B240 can be selected by clicking the mouse, and a command for displaying a bulletin board registration screen (a screen for inputting a message and registering it in the bulletin board database DB 700) is issued when the button B240 is selected. It is like that.

  In the reagent information display area A235, information on the remaining amount of reagent, the predicted usage amount, and the excess / deficiency amount is displayed for each measurement item. The reagent information display area A235 is a table-like area composed of a plurality of rows, and each row corresponds to one measurement item. The reagent information display area A235 is divided into two columns, and the name of the measurement item is displayed in each row in the left column. In the right column, numerical information C241 of the remaining amount of the reagent, numerical information C242 of the excess / deficiency of the reagent, and graphic information G243 schematically showing the remaining amount of the reagent, the predicted usage amount, and the excess / deficiency amount, Is displayed. The graphic information G243 includes a horizontally long bar G244 indicating the reagent remaining amount. The bar G244 is displayed in green, and the remaining amount corresponds to the length. That is, the longer the remaining amount, the longer the length of the bar G244, and the smaller the remaining amount, the shorter the length of the bar G244. The bar G244 is displayed so as to extend rightward from the left end (hereinafter referred to as “reference position”). That is, the reference position of the area where the bar G244 can be displayed corresponds to the state where the remaining amount of the reagent is “0”, and the right end position (hereinafter referred to as “upper limit position”) of the area is full of the reagent. It corresponds to the state. When the reagent remaining amount is “0”, the bar G244 is not displayed, and when the reagent is full, the bar G244 is displayed in the range from the reference position to the upper limit position of the area. For example, when the remaining amount of the reagent is 70%, the bar G244 having a length of 70% with respect to the entire length from the reference position to the upper limit position extends rightward from the reference position. Is displayed. In this way, the user can visually grasp the approximate reagent remaining amount simply by confirming the length of the bar G244.

  In addition, on both upper and lower sides of the bar G244, a bar G245 indicating the estimated usage amount of the reagent is displayed in parallel with the bar G244. The bar G245 is gray and is narrower than the bar G244. The bar G245 can be displayed in the range from the reference position to the upper limit position, and the amount of predicted usage corresponds to the length. That is, the greater the predicted usage amount, the longer the length of the bar G245, and the smaller the predicted usage amount, the shorter the length of the bar G245. The bar G245 is displayed so as to extend rightward from the reference position. That is, when the predicted usage amount is “0”, the bar G245 is not displayed, and when the predicted usage amount is full of the reagent container, the bar G245 is displayed in the range from the reference position to the upper limit position of the region. The For example, when the estimated usage amount of the reagent is 70% of the full reagent container, the bar G245 having a length of 70% with respect to the entire length from the reference position to the upper limit position is It is displayed so as to extend rightward from the reference position. By doing so, it is possible to visually grasp the approximate estimated usage amount of the reagent only by the user confirming the length of the bar G245.

  Further, since the bars G244 and G245 are displayed in parallel so as to be adjacent to each other, and are displayed so as to extend to the right according to the capacity from the same reference position, the user can determine the current reagent remaining amount and the estimated usage amount. Can be easily compared.

  The difference between the reagent remaining amount and the predicted usage amount is displayed as an excess / deficiency amount C242. Specifically, when the remaining amount of the reagent exceeds the predicted usage amount, the remaining amount of the reagent, that is, the remaining amount of the reagent when the predicted usage amount is consumed is displayed as the excess / deficiency amount C242. In this case, the reagent remaining amount bar G244 is longer than the predicted usage amount bar G245, and the bar G244 protrudes to the right of the right end of the bar G245. This protruding amount corresponds to an excessive amount of reagent. On the other hand, when the predicted usage exceeds the reagent remaining amount, when the reagent shortage amount, that is, when all the reagent remaining amount is consumed, the reagent amount necessary for the day is further displayed as the excess / deficiency amount C242. In this case, the predicted usage amount bar G245 is longer than the reagent remaining amount bar G244, and the bar G245 protrudes to the right of the right end of the bar G244. This amount of protrusion corresponds to an insufficient amount of reagent. Such a shortage is displayed by a red bar G246. That is, the shortage amount bar G246 is displayed so as to be adjacent to the right side of the reagent remaining amount bar G244 in the range from the right end of the reagent remaining amount bar G244 to the right end of the predicted usage amount bar G245. For example, when the remaining amount of the reagent is 60% with respect to the total capacity of the reagent container and the predicted use amount is the total capacity of the reagent container, the length is 60% with respect to the entire length from the reference position to the upper limit position The bar G244 is displayed so as to extend rightward from the reference position, and the bar G245 is displayed in a range from the reference position to the upper limit position. At this time, the bar G246 is displayed in a range from the right end of the bar G244 to the right end of the bar G245 (see the measurement item “HBsAb” in FIG. 15). Further, when the remaining amount of the reagent is “0” and the predicted usage amount is the full capacity of the reagent container, a shortage bar G246 is displayed in the entire range from the reference position to the upper limit position (measurement item “ FT3 "). Furthermore, when the remaining amount of the reagent is “0” and the predicted usage amount is 5% of the total capacity of the reagent container, a bar having a length of 5% of the length from the reference position to the upper limit position is displayed. G246 is displayed so as to extend rightward from the reference position (see measurement item “TestA” in FIG. 15). By doing in this way, a user can grasp | ascertain the rough excess and deficiency amount of a reagent easily.

  When the excess / deficiency amount C242 is 0 or a positive value, the excess / deficiency amount C242 is displayed in the first color (black). On the other hand, when the excess / deficiency amount C242 is a negative value, the excess / deficiency amount C242 is displayed in the second color (red). Therefore, the user can easily determine which reagent needs to be replaced and which reagent does not need to be replaced based on the color of the excess / deficiency amount C242.

  Above the reagent information display area A235, a button B247 on which a character string “setup” is displayed is provided. The button B247 can be selected by a mouse click operation, and a command for displaying a setup screen (to be described later) is issued when the button B247 is selected.

  In the consumable information display area A236, whether or not replenishment / exchange of consumables other than the reagent is necessary is displayed for each consumable. More specifically, in the consumable information display area A236, the cuvette remaining amount icon C248 indicating whether or not the cuvette supply unit 10 needs to be replenished, and the pipette tip 80 is replenished in the pipette tip supply unit 13. Pipette tip remaining amount icon C249 indicating whether or not it is necessary, filter paper replacement icon C250 indicating whether or not the filter paper 90c needs to be replaced, and a trash can icon indicating whether or not the amount of the waste container 910 is greater than or equal to a predetermined amount. C251, drainage icon C252 indicating whether or not the amount of waste liquid container 920 is greater than or equal to a predetermined amount, line washer replacement icon C253 indicating whether or not the line washer container 930 needs to be replaced, and B / F separation A B / F separation cleaning liquid replacement icon C254 indicating whether or not the cleaning liquid container 940 needs to be replaced; A probe washer exchange icon C255 indicating whether or not it is necessary to replace the blanking washer container 950, and the R4 / R5 exchange icon C256 is provided which indicates whether or not it is necessary to replace the R4 / R5 reagent.

  The remaining cuvette icon C248 indicates remaining cuvette information in the cuvette supply unit 10. When a cuvette of a predetermined amount or more is stored in the cuvette supply unit 10, a gray figure is displayed on the remaining cuvette icon C248. On the other hand, when the CPU 401 determines that the remaining amount of the cuvette in the cuvette supply unit 10 is less than a predetermined amount based on the output signal of the remaining amount sensor 10a, the figure of the remaining cuvette icon C248 is displayed in red. Thus, the display color of the figure of the remaining cuvette icon C248 indicates whether or not the cuvette needs to be replenished.

  Similarly, the pipette tip remaining amount icon C249 indicates the remaining amount information of the pipette tip in the pipette tip supply unit 13. In the pipette tip supply unit 13, when the pipette tip capacity changes from a predetermined amount to less than a predetermined amount, the figure of the pipette tip remaining amount icon C249 changes from gray to red based on the output signal of the remaining amount sensor 13a. Switch to Thus, the display color of the figure of the remaining pipette tip icon C249 indicates whether or not the pipette tip needs to be replenished.

  When the number of times the filter paper 90c installed in the measurement unit 2 is used is less than a predetermined value, a gray graphic is displayed on the filter paper replacement icon C250. Gray is a display color indicating that it is not necessary to replace the filter paper. On the other hand, when the CPU 401 of the information processing unit 4 counts the number of times the filter paper is used and reaches a predetermined value or more, the CPU 401 displays a red graphic on the filter paper replacement icon C250. Red is a display color indicating that the filter paper needs to be replaced. Thus, the display color of the graphic of the filter paper replacement icon C250 indicates whether or not the filter paper needs to be replaced.

  In the trash can icon C251, information on the amount of waste contained in the waste container 910 is shown. When the amount of waste contained in the waste container 910 is less than a predetermined amount, a gray figure is displayed on the trash can icon C251. On the other hand, when the CPU 401 determines that the amount of waste contained in the waste container 910 is greater than or equal to a predetermined amount based on the output signal of the amount sensor 910a, the figure of the trash can icon C251 is displayed in red. Thus, the display color of the figure of the trash can icon C251 indicates whether or not the waste contained in the waste container 910 needs to be processed.

  The drainage icon C252 indicates information on the amount of waste liquid contained in the waste liquid container 920. The drain icon C252 includes two figures. The two graphics correspond to each of the two containers in the waste liquid container 920. When the amount of waste liquid contained in one container is less than a predetermined amount, the graphic corresponding to the container is displayed in gray.
