Description

[0001] This application is a divisional application of the Chinese invention patent application filed by the same applicant with application number 201910935609.0, application date September 29, 2019, and name “Display method, sample analysis device and storage medium”. Technical Field

[0002] The present invention relates to a display method and the like in a sample analyzer that analyzes a sample using a plurality of reagents. Background Art

[0003] It is now known that there is a sample analysis device that has the function of automatically measuring measurement items set for each sample. This sample analysis device places consumables such as reagents used in the measurement of each measurement item in a housing, and uses these consumables to automatically measure certain measurement items for each analysis object sample. For example, the sample analysis device can automatically perform the following steps (1) to (4) while sequentially replacing the analysis object samples. (1) The step of dispensing the sample into a reaction cup, (2) the step of taking out the reagent corresponding to the measurement item from the reagent container and mixing it with the sample to prepare the measurement sample, (3) the step of measuring each measurement item, and (4) the step of performing analysis based on the measurement results. This sample analysis device is very convenient when multiple samples need to be analyzed continuously.

[0004] However, when analyzing multiple samples continuously, the sample analyzer must be loaded with consumables such as cuvettes and reagents sufficient for the number of samples and the number of measurement items before the continuous analysis begins. If the number of consumables loaded in the sample analyzer is insufficient, the analysis of the samples may be stopped midway or the sample analyzer may malfunction.

[0005] Therefore, in order to properly manage the reagents placed in the sample analyzer, some devices display a display interface including icons corresponding to the reagents arranged in the device on the display unit, and then display information such as the status of the reagents used in the sample analysis and the measurement items on the display interface.

[0006] The above-mentioned display interface can be cited as disclosed in Patent Document 1. Patent Document 1 discloses a display interface, which includes: a reagent configuration display area A that displays a mark M corresponding to the reagent placed in the sample analyzer, and an operation means display area B that displays the operation on the reagent (refer to Fig.24 ). In this display interface, when the symbol M corresponding to the reagent is selected from the reagent configuration display area A, if a button included in the operation means display area B is selected, a certain operation will be performed on the reagent. For example, the reagent can be replaced or a new reagent can be added.

[0007] Prior art literature Patent Literature Patent Document 1: Japanese Patent Application Publication No. 2009-036513. Summary of the invention

[0008] Technical problem to be solved by the invention Unlike the management of cuvettes, etc., which can be properly replenished in the sample analyzer, the management of reagents requires complex and time-consuming operations and certain operations, which will become a burden on the operator of the sample analyzer. For example, the amount consumed in sample analysis varies for each reagent, so the remaining amount of each reagent must be confirmed before the analysis begins. In addition, the expiration date of the reagents used in the analysis of each batch of samples will also be different, so in order to obtain highly reliable analysis results, it is necessary to properly manage the expiration date of each reagent.

[0009] More specifically, when the remaining amount of a reagent is less than the amount used in the continuous analysis, the operator needs to replace or add each reagent separately. If there is a reagent with an unknown remaining amount, the operator needs to instruct the device to measure the remaining amount of the reagent. For unregistered batches of reagents, the operator needs to enter the expiration date and other information to be registered for each reagent. If there is a reagent whose barcode information on the reagent container fails to be read, the operator needs to instruct the device to read the barcode information again, or manually enter the information.

[0010] When performing such a certain operation, in the display interface disclosed in Patent Document 1, the certain operation must be performed for each mark. That is, the operator needs to input for each reagent to perform the certain operation. This method is relatively safe, but it is relatively cumbersome when performing a certain operation for more than two reagents, and there is room for improvement in terms of reducing the burden on the operator.

[0011] The present invention is to solve the above-mentioned technical problems, and one of its objects is to provide a display method that reduces the burden on an operator who manages reagents in a sample analyzer.

[0012] Technical means to solve technical problems In order to solve the above-mentioned technical problem, a display method according to one or more aspects of the present invention is a display method in a sample analysis device (30) having a placement portion (441) for placing a plurality of reagent containers (442) for placing reagents used for sample analysis, the display method comprising the following steps: a display step of displaying a plurality of icons (700) corresponding to each placement portion (441) on a display portion (33c), a selection step of accepting selection of a plurality of icons (700) from the icons displayed on the display portion (33c), and an operation acceptance step of accepting an instruction for a certain operation associated with the plurality of icons (700) selected in the selection step.

[0013] According to the technical solution, a plurality of icons (700) can be selected and the sample analysis device (30) can be made to perform certain operations associated with the plurality of icons (700). Therefore, the operator of the sample analysis device (30) can perform certain operations associated with the plurality of icons through a single operation input, thereby simplifying the operation.

[0014] Here, the icon ( 700 ) refers to, for example, an icon displayed on the reagent management interface ( 600 ) of the display unit ( 33 c ) of the sample analyzer ( 30 ).

[0015] Each reagent has reagent information corresponding thereto, and the icon (700) is displayed in a form corresponding to the reagent information.

[0016] According to the technical solution, the icon (700) is displayed in the form of reagent information corresponding to the reagent represented by the icon (700). Therefore, the operator of the sample analysis device (30) can visually identify the reagent information by looking at the icon (700).

[0017] Reagent information refers to various information related to the reagent. The reagent information can also include information related to the state of the reagent configured in the placement section (441) of the sample analysis device (30). The reagent information includes, for example, information for identifying the reagent, information indicating the reagent state, and information related to the measurement items of the reagent. The reagent container is sometimes not configured in the placement section (441), so the reagent information can also include information indicating whether the placement section (441) is configured with a reagent container.

[0018] Certain operations may include: (i) determining the remaining amount of a reagent, (ii) editing reagent-related information, and (iii) obtaining reagent-related information.

[0019] According to the technical solution, the sample analysis device (30) performs (i) measurement of the reagent remaining amount, (ii) editing of reagent related information, and (iii) acquisition of reagent related information on the reagents represented by the plurality of icons (700) selected in the selection step. Therefore, the operator of the sample analysis device (30) can perform (i) measurement of the reagent remaining amount, (ii) editing of reagent related information, and (iii) acquisition of reagent related information on the plurality of reagents in a unified manner.

[0020] The configuration of the icon ( 700 ) in the display interface displayed by the display unit ( 33 c ) corresponds to the configuration of the placement unit ( 441 ) on which the reagent container ( 442 ) represented by the icon ( 700 ) is mounted.

[0021] According to the technical solution, the configuration of the icon (700) in the display unit (33c) and the configuration of the reagent container (442) in the reagent table (440) correspond to each other. Therefore, the operator of the sample analysis device (30) can intuitively recognize the actual configuration of the reagent container (442) on the display interface, thereby further improving operability.

[0022] The sample analysis device (30) involved in one or more aspects of the present invention comprises a plurality of placement parts configured to place reagent containers for reagents used to analyze samples, a display part, an input part, and a control part. The control part is configured to: control the display part to display icons respectively associated with the placement parts; and accept, through the input part, a selection of an icon from the icons displayed on the display part; and receive, through the input part, an instruction for a certain operation related to the selected icon.

[0023] According to the technical solution, a sample analysis device (30) capable of accepting instructions is provided, wherein the instructions are used to obtain certain operations associated with a plurality of icons (700).

[0024] One or more aspects of the present invention involve a permanent computer-readable storage medium that stores a program that can be executed by a computer to perform operations, the operations including: displaying icons respectively associated with a placement portion on a display portion, the placement portion being configured as a reagent container for placing reagents for sample analysis; accepting a selection of an icon from the icons displayed on the display portion; and receiving instructions for a certain operation related to the selected icon.

[0025] According to the technical solution, a computer-readable non-volatile storage medium is provided, in which a program for controlling a sample analysis device (30) is stored, so that the device can receive instructions for certain operations associated with a plurality of icons (700).

[0026] Effects of the Invention According to the present invention, a display method is provided that reduces the burden on an operator who manages reagents in a sample analyzer. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] Hereinafter, one embodiment of the present invention will be described based on the drawings.

[0029] First, refer to Figure 1 , 2 , the structure of the sample analysis device 30 involved in one embodiment of the present invention is described. Figure 1 As shown, the sample analyzer 30 includes a measuring unit 32 and an analyzing unit 33 .

[0030] The measurement unit 32 includes a measurement control unit 32a, a measurement storage unit 32b, Figure 2 The various mechanism parts shown. The measurement control part 32a is, for example, a CPU. The measurement storage part 32b is, for example, a ROM, a RAM, and a hard disk. The measurement control part 32a controls each part in the measurement part 32 according to the program and data stored in the measurement storage part 32b. The measurement control part 32a performs the measurement required in the blood coagulation analysis of the sample, for example, and sends the measurement result to the analysis part 33.

[0031] The analysis unit 33 includes an analysis control unit 33a, an analysis storage unit 33b, a display unit 33c, and an input unit 33d. The analysis control unit 33a is, for example, a CPU. The analysis storage unit 33b is, for example, a ROM, a RAM, or a hard disk. The analysis control unit 33a controls each unit in the analysis unit 33 and the measurement unit 32 according to the program and data stored in the analysis storage unit 33b. The display unit 33c is, for example, a liquid crystal display. The input unit 33d is, for example, a mouse or a keyboard. The display unit 33c and the input unit 33d may also be integrally formed by a touch screen display or the like.

[0032] Here, the analysis control unit 33a may be implemented by hardware (for example, using a logic circuit formed on an integrated circuit or the like). Alternatively, the analysis control unit 33a may be implemented by software (for example, using a device having one or more processors and a computer-readable storage medium storing a program for causing the computer to implement various functions).

[0033] The analysis control unit 33a performs, for example, blood coagulation analysis of the sample based on the measurement results received from the measurement unit 32. At this time, the analysis control unit 33a analyzes the following measurement items: PT, APTT, Fbg, exogenous coagulation factors, intrinsic coagulation factors, coagulation factor XIII, HpT, TTO, FDP, D-dimer, PIC, FM, ATIII, Plg, APL, PC, VWF:Ag, VWF:RCo, ADP, collagen, adrenaline, etc.

[0034] like Figure 2As shown, the measuring unit 32 is arranged behind the transport unit 31. In one embodiment, the measuring unit 32 performs the measurement required for blood coagulation analysis. In this case, the sample contained in the sample container 20 is plasma.

[0035] The liquid stored as a sample in the sample container 20 is not limited to plasma. That is, the sample stored in the sample container 20 is not limited to plasma, and may be whole blood, serum, urine, lymph, body cavity fluid, etc. For example, when the sample is subjected to a blood cell test related measurement by the measuring unit 32, the sample can be whole blood. For example, when the sample is subjected to a blood coagulation test, an immunological test, or a biochemical test related measurement by the measuring unit 32, the sample can be plasma. For example, when the sample is subjected to an immunological test or a biochemical test related measurement by the measuring unit 32, the sample can be serum.

[0036] The measurement section 32 includes a sample dispensing section 410 , a reaction container stage 420 , a heating stage 430 , a reagent stage 440 , reagent dispensing sections 450 and 460 , a transfer section 470 , a detection section 480 , and a sample dispensing section 490 .

[0037] The sample dispensing unit 410 includes an aspirating unit 411, an arm 412, and a mechanism unit 413. The sample dispensing unit 410 aspirates a sample from a sample container 20 placed on the sample rack 10 and located at the aspirating position 301 via the aspirating unit 411. Then, the sample dispensing unit 410 discharges the aspirated sample into a reaction container 422 placed in a placement hole 421 of a reaction container stage 420.

[0038] The sample dispensing unit 490 is provided with a pipetting unit 491, an arm 492, and a mechanism unit 493 in the same manner as the sample dispensing unit 410. The pipetting unit 491 is provided at the front end of the arm 492. The pipetting unit 491 is composed of a suction nozzle. The mechanism unit 493 rotates the arm 492 in the circumferential direction and moves it in the vertical direction. Thus, the pipetting unit 491 can move in the circumferential direction and in the vertical direction.

[0039] The sample dispensing unit 490 lowers the pipetting unit 491 from the upper side of the sample container 20 placed on the sample rack 10 and located at the pipetting position 302 on the rack transport unit 42, and inserts the sample container 20. Then, the sample dispensing unit 490 aspirates the sample from the sample container 20 via the pipetting unit 491, and discharges the aspirated sample into the reaction container 422 placed in the placement hole 421 of the reaction container stage 420.

[0040] The reaction container table 420 is annular in a top view and is disposed outside the reagent table 440. The reaction container table 420 can rotate in a circumferential direction. The reaction container table 420 has a plurality of placement holes 421 for placing reaction containers 422.

[0041] The heating stage 430 has a plurality of receiving holes 431 for receiving the reaction container 422 and a transfer unit 432 for transferring the reaction container 422. The heating stage 430 has a circular outline in a plan view and can rotate in a circumferential direction. The heating stage 430 heats the reaction container 422 placed in the receiving holes 431 to 37°C.

[0042] After the sample is discharged into the reaction container 422 placed on the reaction container stage 420, the reaction container stage 420 rotates and the reaction container 422 containing the sample is transferred to the vicinity of the heating stage 430. Then, the transfer unit 432 of the heating stage 430 clamps the reaction container 422 and places it in the placement hole 431 of the heating stage 430.

[0043] The reagent table 440 is provided with a plurality of placement parts 441. Reagent containers 442 containing reagents used in the measurement required for blood coagulation analysis can be placed in the placement parts 441. That is, a plurality of reagent containers 442 can be placed in the reagent table 440. The reagent table 440 can rotate in a circumferential direction. The reagent table 440 is provided with a plurality of reagent containers 442 containing reagents used in the measurement of the measurement items.

[0044] The reagent dispensing section 450 includes a suction nozzle 451 and a mechanism section 452. The mechanism section 452 allows the suction nozzle 451 to move horizontally in a manner that crosses the reagent table 440, and allows the suction nozzle 451 to move vertically. Similarly, the reagent dispensing section 460 includes a suction nozzle 461 and a mechanism section 462. The mechanism section 462 allows the suction nozzle 461 to move horizontally in a manner that crosses the reagent table 440, and allows the suction nozzle 461 to move vertically. The reagent dispensing sections 450 and 460 are arranged on the lower side of the upper side of the housing of the measuring section 32.

[0045] The reagent dispensing parts 450 and 460 dispense reagents into the reaction container 422 heated on the heating stage 430. When dispensing reagents, the transfer part 432 or the transfer part 470 takes out the reaction container 422 from the placement hole 431 of the heating stage 430 and places it at a certain position near the heating stage 430. Then, the reagent dispensing parts 450 and 460 aspirate the reagent from the reagent container 442 via the suction nozzles 451 and 461, and discharge the aspirated reagent into the reaction container 422. Thus, the sample and the reagent are mixed to prepare a measurement sample. After that, the transfer part 470 places the reaction container 422 in the placement hole 481 of the detection part 480.

[0046] The measuring principle of the detection unit 480 is, for example, a coagulation method, a synthetic matrix method, an immunoturbidimetric method, an agglutination method, etc. The detection unit 480 includes a plurality of placement holes 481. The detection unit 480 irradiates light to the reaction container 422 placed in the placement hole 481, receives light transmitted through the measurement sample, and outputs a signal corresponding to the received light intensity. The measurement control unit 32a of the measurement unit 32 stores the signal output from the detection unit 480 as a measurement result and sends the measurement result to the analysis unit 33.

[0047] 〔Departments involved in the display method〕 Next, refer to Figure 3 Each unit involved in a display method according to an embodiment of the present invention will be described.

[0048] exist Figure 3 In the embodiment, the measurement unit 32 includes a barcode reader 32c (the measurement control unit 32a is described above, so the description thereof is omitted). The measurement control unit 32a includes a barcode reader 41. The barcode reader 41 receives information read from the barcode by the barcode reader 32c and transmits it to each unit.

[0049] The analysis control unit 33 a includes a display control unit 51 , a related icon extraction unit 52 , and an icon generation unit 54 .

[0050] The display control unit 51 receives data required for generating a display interface from each unit, and causes the display unit 33c to display the display interface. The related icon extraction unit 52 extracts related icons 700 belonging to the icon 700 based on the input of selecting an icon 700 via the input unit 33d. The icon generation unit 54 obtains the reagent information corresponding to the received barcode information by referring to the reagent information database 36 stored in the analysis storage unit 33b, and generates an icon 700 including the reagent information.

[0051] The main structure of the above-mentioned measurement control unit 32a and analysis control unit 33a is an example. The two control units can be implemented by hardware (for example, a logic circuit formed on an integrated circuit, etc.) or by software (for example, a device having one or more processors and a computer-readable storage medium storing programs that enable the computer to implement various functions).

[0052] Next, refer to Figure 4 The following describes a process flow when executing a display method according to an embodiment of the present invention.

[0053] In S10 , the power of the sample analyzer 30 is turned on. Thus, the sample analyzer 30 is activated.

[0054] In S20, the barcode information is read in the measuring unit 32. Specifically, the barcode reader 32c reads the barcode provided in the reagent container 442 or the reagent container rack 440a. The read barcode information is sent to the analyzing unit 33. The details of step S20 will be described in detail later.

[0055] In S30, an icon is displayed on the display unit 33c. Specifically, the icon generation unit 54 reads the reagent information from the reagent information database 36 and generates an icon. At this time, the icon generation unit generates icons for each reagent placed on the reagent table 440. The generated icon is sent to the display control unit 51 and displayed on the display unit 33c.

[0056] Here, the reagent information database 36 is a relational database having fields such as holder number, reagent name, batch number, remaining quantity, remaining number of uses, storage date, storage time, etc. (see Figure 5 In the following description, "reagent" refers to the reagent container 442 and the reagent stored in the reagent container 442. The holder number is a number assigned to the placement section 441 for placing the reagent. Each record corresponds to one of the multiple reagents arranged on the reagent table 440.

[0057] In S40, an operation of selecting a plurality of icons 700 from the icons displayed on the display unit 33c is received via the input unit 33d. In one embodiment, the operation is the selection of one icon 700. At this time, the associated icon extraction unit 52 extracts the associated icons 700 of the selected one icon 700 and sends it to the display control unit 51. The display control unit 51 causes the display unit 33c to display the selected one icon 700 and the associated icons 700 of the one icon in a form that can be distinguished from other icons 700. Examples of different forms include, for example, changing the color of the icon 700, changing the brightness of the icon 700, changing the shape of the icon 700, etc.

[0058] In S50, input of a certain operation is received via the input unit 33d. The operation input may also be processed by the analysis control unit 33a. Alternatively, it may be processed by the measurement control unit 32a after being sent to the measurement unit 32. The result of the certain operation is that the reagent information changes from the time point of S30. For example, the reagent information may be newly input, or the reagent may be supplemented.

[0059] In S60, the reagent information changed in the step S50 is written into the reagent information database 36. Thus, the reagent information included in the reagent information database 36 is updated. Thereafter, an icon including the updated reagent information is displayed on the display unit 33c by the same process as in S30.

[0060] In S70 , the power of the sample analyzer 30 is turned off. Thus, the operation of the sample analyzer 30 ends.

[0061] [Barcode information reading steps] Reference Figure 6 , 7 The processing of the barcode information reading step ( S20 ) is described. In S20 , the barcode provided on the reagent container 442 or the reagent container rack 440 a is read.

[0062] Figure 6 This is a perspective view of a reagent container rack 440a. A plurality of reagent container racks 440a are arranged on the reagent table 440. The reagent container rack 440a is provided with a placement portion 441, and a reagent container 442 can be placed in the placement portion 441 (refer to the placement portion 441 on the right). By designing the reagent container rack 440a so that the inner diameter of the placement portion 441 is different, or by installing an adapter (not shown) in the placement portion 441, reagent containers 442 of various sizes can be placed in the placement portion 441.

[0063] Here, the reagent container 442 is provided with a barcode A. A barcode B is provided on the front side of the outer side surface of the mounting portion 441 , and a barcode C is provided on the inner side surface of the mounting portion 441 .

[0064] Barcode A includes detailed information of the reagent stored in the reagent container 442 (reagent name, reagent container type, batch number, reagent expiration date, etc.). Barcode B includes position information (holder number) for identifying the position of each mounting portion 441. Barcode C includes information indicating that there is no mounted reagent container 442.

[0065] Figure 7 This is a flowchart of the processing flow in the barcode information reading step ( S20 ). In S21 , the states of various components (barcode reader 32 c and the like) related to the reading of the barcode information are confirmed.

[0066] In S22, the barcode of the reagent container 442 is read. Specifically, the barcode reader 32c sequentially reads the barcodes of the reagent container 442 or the reagent container rack 440a. Figure 6 In the example, the barcode B on the right is read first, and then the barcode A is read. Thus, the right placement section 441 is associated with the detailed information of the reagent stored in the reagent container 442. Next, the barcode B on the left is read, and then the barcode C is read. Thus, the left placement section 441 is associated with the information indicating "no reagent container".

[0067] In S23, it is determined whether there is a placement section 441 where the barcode information reading fails. Specifically, after the barcode reader 32c reads the barcode B, it is determined whether there is a situation where neither the barcode A nor the barcode C is read. For example, if the reagent container 442 is sideways, both the barcode A and the barcode C cannot be read, so S23 is determined to be yes. If it is determined to be no, the process goes to S24, and if it is determined to be yes, the process goes to S25.

[0068] In S24, the reagent information database is referenced to obtain the reagent information associated with the barcode information. Specifically, the barcode reader 41 sends the obtained barcode information to the icon generator 54. The icon generator 54 references the reagent information database 36 stored in the analysis storage unit 33b to obtain the reagent information corresponding to the received barcode information.

[0069] In S25, the reagent table 440 is rotated to move the reagent container rack 440a including the receiving portion 441 whose barcode information has failed to be read to a position where the reagent container 442 can be replaced. Thus, the operator can replace the reagent container 442 received in the receiving portion 441 whose barcode information has failed to be read or change the orientation of the reagent container 442.

[0070] In S26, the replacement of the reagent container 442 is accepted. This step can be triggered by, for example, closing the cover (not shown) of the reagent table 440. After S26, the process returns to S22 again, and the barcode is read again.

[0071] If the answer is YES in S23, the position information included in the barcode B and the information indicating "barcode reading error" may be associated with each other and displayed as an icon instead of proceeding to S25.

[0072] [Steps for selecting several icons] Below, refer to Figures 8 to 18 The following describes the selection procedure of the plurality of icons 700. The description is based on the interface transition.

[0073] [icon] Figure 8 (a) is a diagram showing an example of an icon 700 displayed on the display unit 33c. In this figure, the icon 700 includes a position display unit 701 that displays the position of the reagent and a reagent name display unit 702 that displays the name of the reagent. The holder number displayed on the position display unit 701 is determined by the icon generating unit 54 based on the information read by the barcode reader 32c from the barcode B provided on the reagent container rack 440a. In addition, the reagent name displayed on the reagent name display unit 702 is determined by the icon generating unit 54 with reference to the barcode information read by the barcode reader 32c from the barcode C provided on the reagent container 442 and the reagent information database 36. The icon representing the diluent or the cleaning solution can also display the position and the name of the reagent by the same method.

[0074] As other reagent information, Figure 8 (a) shows the number of times that the reagent can be used 703, the accuracy management warning 704, the calibration curve warning 705, and the order of use of the reagent 706. The number of times that the reagent can be used 703 is determined by the remaining amount of the reagent and the measurement item, indicating how many measurements can be performed. The accuracy management warning 704 indicates that the accuracy management of the reagent is outside the reference value. The calibration curve warning 705 indicates that the calibration curve corresponding to the reagent batch has not been made. The order of use of the reagent 706 indicates in which order the same reagent is used when it is configured in several placement sections 441. In addition, although not shown in the figure, the elapsed time (unit: hour) since the reagent was set and the remaining amount of the reagent (unit: mL) can also be displayed as reagent information.

[0075] In addition, there is also reagent information displayed in a larger area. Figure 8 The following explains (b) to (l) in the figure. Figure 8 (b) indicates "no reagent", (c) indicates "use prohibited", and (d) indicates "expired". Icons 700 displaying these reagent information cannot be selected in the selection step. The reason is as follows. Regarding the icon 700 displaying "no reagent", no reagent is configured in the corresponding placement section 441. Therefore, no operation can be performed on the placement section 441. Regarding the icon 700 displaying "use prohibited", the container size of the reagent to be configured in the placement section 441 is incorrect (for example, a small reagent container 442 is configured in the placement section 441 for setting a large reagent container 442). Therefore, the sample analyzer 30 cannot be operated until the reagent container 442 is reconfigured to the correct position. Regarding the icon 700 displaying "use expired", the use period of the corresponding reagent has expired. It is not recommended to use expired reagents, so the operation of the sample analyzer 30 has been prohibited by setting.

[0076] Figure 8 (e) indicates "barcode reading error (no last reagent information)", (f) indicates "barcode reading error (last reagent information)", (g) indicates "unregistered reagent", and (h) indicates "unregistered reagent batch". For these reagent information, either the barcode information reading failed or the information is not stored in the reagent information database 36, and therefore, it cannot be displayed. Figure 8 The icon 700 of (a) is displayed as reagent information.

[0077] The sample analyzer 30 identifies each reagent container 442 based on the information stored in the reagent information database 36. Figure 8The sample analyzer 30 cannot recognize the reagent container 442 corresponding to the reagent information icon 700 shown in (e) to (h) of FIG. 3 , which reagent is stored, how much is left, what the calibration curve is, etc. As a result, the sample analyzer 30 cannot use the reagent container 442 corresponding to the reagent information icon 700 in sample analysis.

[0078] "Barcode reading error (no last reagent information)" is displayed when (i) the reagent barcode reader 350 fails to read information from the barcode A of the reagent container 442, and (ii) the reagent associated with the same placement section 441 is not registered in the reagent information database 36. For example, when a new reagent is placed in the placement section 441 where no reagent was placed when the sample analyzer 30 was used last time, and the barcode A fails to be read, this is an example.

[0079] For the reagent container 442 for which the icon 700 of "barcode reading error (no previous reagent information)" is displayed, the operator can edit the reagent information and register it in the reagent information database 36. By this operation, the display of the icon 700 changes from "barcode reading error" to " Figure 8 In addition, the analysis control unit 33a identifies the reagent container 442 corresponding to the icon 700 based on the reagent information newly registered in the reagent information database 36. As a result, the sample analyzer 30 can use the reagent container 442 corresponding to the icon 700 in the sample analysis. For the specific processing flow when editing the reagent information, please refer to the item [Example 2] described later.

[0080] "Barcode reading error (previous reagent information available)" is displayed when (i) the barcode reader 32c fails to read information from the barcode A of the reagent container 442, and (ii) the reagent associated with the same placement section 441 is registered in the reagent information database 36. For example, this is the case when the placement section where the reagent was placed when the sample analyzer 30 was used last time is configured with the same reagent, but the barcode A reading fails. For the icon 700 displayed with "Barcode reading error (previous reagent information available)", the operator can (i) edit the reagent information, and (ii) restore the reagent information by referring to the reagent information database 36 based on the position information of the placement section 441 corresponding to the icon 700.

[0081] As described above, when the reagent information is edited and registered in the reagent information database 36, the sample analyzer 30 can use the reagent container 442 corresponding to the icon 700 in the sample analysis. On the other hand, when the reagent information is restored, the analysis control unit 33a obtains information for identifying the reagent container 442 corresponding to the icon 700 from the reagent information database 36. As a result, the sample analyzer 30 can use the reagent container 442 corresponding to the icon 700 in the sample analysis. For the specific processing flow when restoring the reagent information, please refer to the item [Example 3] described later.

[0082] "Unregistered reagent" is displayed when the barcode reader 32c reads information from the barcode A of the reagent container 442 but the reagent name is not registered in the reagent information database 36. For the icon 700 displayed with "Unregistered reagent", the operator can edit the reagent information. "Unregistered reagent batch" is displayed when the barcode reader 32c reads information from the barcode A of the reagent container 442 but the batch is not registered in the reagent information database 36. For the icon 700 displayed with "Unregistered reagent batch", the operator can edit the reagent information. If the reagent information is edited and registered in the reagent information database 36, as described above, the sample analyzer 30 can use the reagent container 442 corresponding to the icon 700 in the sample analysis.

[0083] Figure 8 (i) indicates "remaining amount", (j) indicates "remaining amount warning", (k) indicates "reagent exhausted", and (l) indicates "remaining amount unknown". These are reagent information related to the remaining amount of the reagent, and usually "remaining amount" is displayed. When the remaining amount of the reagent is below a certain threshold, "remaining amount warning" is displayed, when there is no remaining amount, "no remaining amount" is displayed, and when the remaining amount is unknown, "remaining amount unknown" is displayed. For icons showing these reagent information, the operator can instruct the sample analyzer 30 to measure the remaining amount.

[0084] By measuring the remaining amount, the analysis control unit 33a can grasp the accurate amount of reagent stored in the reagent container 442 corresponding to each icon 700. When the amount of reagent is less than a certain threshold, the analysis control unit 33a can notify and urge the replenishment of reagent (for example, by changing the reagent information displayed by the icon 700). In addition, the analysis control unit 33a can also make the measurement unit 32 operate to receive reagent replenishment (for example, by rotating the reagent table 440 to a certain position). By replenishing the reagent, the operator can avoid the situation where the reagent remaining amount is insufficient in the middle of continuous analysis, and can make the sample analyzer 30 operate efficiently.

[0085] [Type of reagent information] Fig. 9 About Figure 8 (e) to (l) of the reagent information show what operations the operator can perform. Fig. 9 In the table, a "type" is set for each reagent information, and one or more reagent information are classified into one type.

[0086] The reagent status represented by the reagent information classified as the same type has at least some common items. In one embodiment, the common item refers to the common operation that the operator can perform on the reagent. For example, "unregistered reagent" and "unregistered reagent batch" are common in that "information is read from the barcode A of the reagent container 442, but part of the reagent information (reagent name or reagent batch) is not registered in the reagent information database 36", and are also common in that the operation of "editing reagent information" can be performed. Similarly, "remaining amount", "remaining amount warning", "reagent exhausted" and "remaining amount unknown" are common in that "information is read from the barcode A of the reagent container 442 and the reagent information is obtained from the reagent information database", and are also common in that "remaining amount measurement" or "remaining amount reset" can be performed.

[0087] originally, Fig. 9 The types of reagent information shown are just examples, and other types may be set appropriately according to the purpose. For example, "remaining amount", "remaining amount warning", "reagent exhausted", and "remaining amount unknown" may be set as different types.

[0088] In one embodiment, the related icons 700 that can be selected after selecting one icon 700 (or the icons 700 that are selected together with the one icon 700) are “icons of the same type as the selected one icon 700”. That is, the reagent status represented by the selected one icon 700 and the reagent status represented by the related icons 700 are at least partially the same.

[0089] picture Fig. 9 When the category is set in this way, in one example, the selected one icon 700 and the related icons 700 may display one of "remaining amount", "remaining amount warning", "reagent exhausted" and "remaining amount unknown". In this case, the operator can measure the remaining amount of the plurality of reagents corresponding to the plurality of icons 700 displaying one of "remaining amount", "remaining amount warning", "reagent exhausted" and "remaining amount unknown".

[0090] In one example, the selected icon 700 and the related icons 700 may all display "barcode read error (no last reagent information)". In this case, the operator can edit the reagent information uniformly for the reagent containers 442 corresponding to the icons 700 displaying "barcode read error (last reagent information)". In another example, the selected icon 700 and the related icons 700 may all display "barcode read error (last reagent information)". In this case, the operator can edit the reagent information uniformly for the reagent containers 442 corresponding to the icons 700 displaying "barcode read error (last reagent information)", and can also restore the reagent information uniformly. In another example, the selected icon 700 and the related icons 700 may display either "barcode read error (no last reagent information)" or "barcode read error (last reagent information)". At this time, the operator can edit the reagent information collectively for the reagent containers 442 corresponding to the icons 700 displaying either "barcode reading error (previous reagent information available)" or "barcode reading error (previous reagent information available)".

[0091] In one example, the selected icon 700 and the related icons 700 may display either “unregistered reagent” or “unregistered reagent batch.” In this case, the operator can edit reagent information for the reagent containers 442 corresponding to the icons 700 displaying “unregistered reagent” or “unregistered reagent batch,” for example.

[0092] In one example, the selected one icon 700 and the related icons 700 may correspond to the reagent whose information is read from the barcode A of the reagent container 442 and whose expiration date has not expired ( Fig. 9 In the classification of ", there are icons 700 showing "remaining amount", "remaining amount warning", "reagent exhausted" and "remaining amount unknown". At this time, the operator can, for example, uniformly measure the remaining amount of several reagents corresponding to several icons 700 showing "remaining amount", "remaining amount warning", "reagent exhausted" and "remaining amount unknown", and can also uniformly create calibration curves and uniformly perform accuracy management.

[0093] [Reagent management interface] Fig.10 6 is an overall diagram of the reagent management interface 600. The reagent management interface 600 includes a reagent configuration display area 610, a holder information display area 620, a consumables information display area 630, an overview information display area 640, an operation instruction area 650, and a mode switching unit 680. Here, the display unit 33c has a touch screen function. Therefore, the operator can make a selection or operation by directly touching the buttons displayed on the reagent management interface 600.

[0094] Fig.10The interface design in is an interface design that makes the arrangement of icons 700 correspond to the arrangement of reagents in the placement section 441 of the sample analyzer 30. In the same figure, 38 icons 700 are arranged corresponding to the arrangement status of the reagents arranged on the reagent table 440. And 6 icons 700 are arranged in the reagent arrangement display area 610 at the bottom of the reagent management interface 600 corresponding to the arrangement status of the diluent or the cleaning solution. When the placement section 441 is not arranged with a reagent, an icon 700 containing the reagent information "no reagent" is displayed.

[0095] These icons 700 can be selected by a selection operation (a touch with a finger, a click with a mouse, etc.). Fig.10 In the figure, the icon 700 of A1-10 is displayed so that it can be identified as being selected. Note that the icon 700 (A1-10) is surrounded by a thick frame (in the following figures, the holder name of the corresponding mounting portion 441 is sometimes indicated by the content in parentheses to distinguish each icon 700).

[0096] As described above, various reagent information is displayed in icon 700. For example, Fig.10 In the diagram, icons 700 (A1-10), 700 (A1-7), and 700 (D2-2) all represent reagents used in sample analysis, but the remaining amounts of the reagents are different. Icon 700 (B-2) represents a diluent. Icon 700 (A2-5) indicates that an unregistered reagent is configured.

[0097] The reagent configuration display area 610 displays icons 700 corresponding to the reagents configured in the placement section 441. The holder information display area 620 displays information related to the reagents configured in the placement section 441 corresponding to the icon 700 in the selected state. Such information includes the holder number, reagent name, usage order, available remaining amount (usable amount), remaining number of tests, presence or absence of stirring, batch number, type of reagent container, reagent expiration date, placement date, placement time and elapsed time, etc. The consumables information display area 630 displays the storage amount of washing water and reaction cups, the remaining capacity of the waste liquid tank and the used reaction cup waste box, etc. The overview information display area 640 displays the remaining number of tests that can be performed (determined by the reagent remaining amount, etc.), the reagent remaining amount, the diluent remaining amount, etc. through labels. The operation instruction area 650 contains buttons for instructing to perform certain operations on the reagent corresponding to the selected icon. Fig.10There are four buttons, namely, "remaining quantity measurement" button, "remaining quantity reset" button, "reagent information input" button, and "reagent information recovery" button. By touching the buttons, the reagent corresponding to the icon 700 in the selected state is operated as described in each button. The mode switching unit 680 switches the mode of the reagent management interface 600. The switching between the "normal selection mode" and the "multiple selection mode" is particularly important. This will be described in detail in embodiments 1 to 3.

[0098] [Implementation method 1] Below, refer to Fig.11 The display method according to the first embodiment of the present invention will be described. In the first embodiment, a plurality of reagents are selected in the plurality of selection modes.

[0099] First, tap the mode switching unit 680 to switch to a plurality of selection modes ( Fig.11 (a) in FIG. 1 ). Note that the check box in the mode switching portion 680 is checked. A plurality of icons 700 can be selected in the display interface of the plurality of selection modes.

[0100] from Fig.11 The display interface when icon 700 (A1-10) is selected in the state (a) is as follows: Fig.11 (b) in the figure. In the first embodiment, icon 700 (A1-10) is selected by tapping. At this time, the icon of the reagent associated with the reagent information contained in the selected icon 700 (A1-10) (the second reagent icon), namely icon 700 (A1-8) and icon 700 (A1-2), is displayed brighter. In contrast, the other icons 700 are displayed darker. Thus, icon 700 (A1-10), the associated reagent icons 700 (A1-2), and 700 (A1-8) are displayed in a manner that can be distinguished from the other icons 700.

[0101] That is, in Fig.11 In (b), (i) the first selected icon 700 (A1-10) is displayed so as to be recognized as being selected, and (ii) icons of reagents associated with the reagent information included in the icon 700 (A1-10), namely, icons 700 (A1-2) and 700 (A1-8), are displayed so as to be recognized as being selectable.

[0102] Fig.11 In (b), icons with the same reagent name are used as “related reagent icons.” However, the method of selecting related reagent icons is not limited to this (the same applies to other embodiments).

[0103] from Fig.11 The display interface when icon 700 (A1-8) is selected in the state (b) is Fig.11(c) in the figure. At this time, the additionally selected icon 700 (A1-8) also becomes selected (note that it is surrounded by a thick frame), and together with the initially selected icon 700 (A1-10), two icons are selected. On the other hand, the icon 700 (A1-2) that is selectable but not selected by the operator is not selected.

[0104] Right now, Fig.11 In (c) of FIG. 1 , by selecting the icon 700 ( A1 - 8 ) displayed in a manner that allows recognition that the icon 700 ( A1 - 8 ) is selected, the icon 700 ( A1 - 8 ) is also displayed in a manner that allows recognition that the icon 700 ( A1 - 8 ) is selected.

[0105] [Reference example] As a reference example, refer to Fig.12 Operations in a mode other than the several selection modes (hereinafter referred to as a "normal selection mode") will be described. In this reference example, please note that the check box of the mode switching unit 680 is not checked.

[0106] Fig.12 (a) in the figure shows the state where icon 700 (A1-10) is selected in the normal selection mode. Please note that icon 700 (A1-10) is surrounded by a thick frame. In addition, the surroundings of icons other than icon 700 (A1-10) are neither displayed brightly nor displayed darkly. In other words, the related reagent icons are not displayed in a discernible manner.

[0107] from Fig.12 The display interface when icon 700 (A1-8) is selected in the state (a) is Fig.12 (b) in FIG. 1 . At this time, icon 700 (A1-8) is selected, whereas icon 700 (A1-10) is not selected. That is, when a certain icon 700 is selected, even if another icon 700 is selected, only the selected icon is changed, and multiple icons cannot be selected.

[0108] [Implementation method 2] Below, refer to Fig.13 A display method according to Embodiment 2 of the present invention will be described. In Embodiment 2, a plurality of reagents are selected at once in a plurality of selection modes. Fig.13 (a) in the figure is a state where the tap mode switching unit 680 switches to a plurality of selection modes (i.e., Fig.11 (a) same state as in (a).

[0109] from Fig.13 The display interface when icon 700 (A1-10) is selected in the state (a) is Fig.13(b) in the figure. In the second embodiment, the icon 700 (A1-10) is selected by long pressing. At this time, in addition to the icon 700 (A1-10) selected by the operator, the related reagent icons 700 (A1-2) and 700 (A1-8) are also in the selected state. That is, there is no need for an additional tap operation as in the first embodiment, and the selected icon 700 (A1-10) and the related reagent icons 700 (A1-2) and 700 (A1-8) can be uniformly selected.

[0110] That is, in Fig.13 In (b) of FIG. 1 , icons 700 ( A1 - 2 ), 700 ( A1 - 8 ), and 700 ( A1 - 10 ) are all in a selected state, and are displayed in a manner that allows identification.

[0111] [Implementation method 3] Below, refer to Fig.14 The display method according to Embodiment 3 of the present invention will be described. In Embodiment 3, switching from the normal selection mode to the multiple selection mode and collective selection of multiple reagents are performed by the same operation. Fig.14 (a) in the figure shows a state where the mode switching portion 680 is tapped and switched to the normal selection mode.

[0112] from Fig.14 The display interface when icon 700 (A1-10) is selected in the state (a) is Fig.14 (b) In Embodiment 3, the icon 700 (A1-10) is selected by long pressing. At this time, the selected icon 700 (A1-10) and the related reagent icons 700 (A1-2) and 700 (A1-8) are collectively selected. In addition, the selection mode is also switched, and the mode switching unit 680 is in a checked state.

[0113] [Variant 1] Embodiment 1 and Embodiment 2, or Embodiment 1 and Embodiment 3 (see Fig.15 ). In this modified example, the analysis control unit 33a sets a certain threshold for the time the touch screen is touched, and distinguishes between a light touch (first selection means) and a long press (second selection means). Then, corresponding to the light touch (first selection means) selection, the selected icon 700 (A1-10) is in a selected state, and the related reagent icons 700 (A1-2) and 700 (A1-8) are in a selectable state. On the other hand, corresponding to the long press (second selection means) selection, the selected icon 700 (A1-10) and the related reagent icons 700 (A1-2) and 700 (A1-8) are in a selected state.

[0114] [Variant 2] You can also switch whether to perform unified selection by preparing two types of multiple selection modes (refer to Fig.16 ). That is, in the first selection mode, the selected icon 700 (A1-10) is selected (touch) in accordance with the selection of the icon 700 (A1-10), and the related reagent icons 700 (A1-2) and 700 (A1-8) are selectable. On the other hand, in the second selection mode, the selected icon 700 (A1-10) and the related reagent icons 700 (A1-2) and 700 (A1-8) are selected in accordance with the selection of the icon 700 (A1-10). The difference from the first modification is that it is not necessary to prepare a plurality of selection means.

[0115] [Variant 3] In the above-described embodiment and modified examples, a method of canceling the selection state of icon 700 may be provided.

[0116] (Variant 3-1) As an example of this approach, Fig.17 , there is an example of a method for reselecting an icon in a selected state. In (a), icons 700 (A1-2), 700 (A1-8), and 700 (A1-10) have been selected. In (b), by selecting icon 700 (A1-2), only icons 700 (A1-8) and 700 (A1-10) are selected. Here, the selection means for releasing the selected state of icon 700 may be the same as the selection means for selecting icon 700, or may be different. For example, when selecting icon 700 by tapping once, it may be designed so that the selected state is released by tapping once in the same manner, or it may be designed so that the selected state is released by tapping twice.

[0117] (Variant 3-2) As another example of a method of canceling the selection state of icon 700, Fig.18 , a method for switching from the multiple selection mode to a mode other than the multiple selection mode is illustrated. In (a), icons 700 (A1-8) and 700 (A1-10) are selected, and 700 (A1-2) is in a selectable state. In (b), by switching from the multiple selection mode to the normal selection mode, all icons are in a state where they are not selected. When switching from the multiple selection mode to the normal selection mode, at least one icon 700 may be deselected.

[0118] 〔Certain operation steps〕 Here are three typical examples: Figure 4 The “certain operation” performed in S50 is explained.

[0119] [Example 1: Reagent Remaining Amount Determination] In Example 1, the remaining amount of the reagents corresponding to the selected icons 700 is measured. Fig. 9 This operation can be performed on the reagent information icons including "remaining amount", "remaining amount warning", "no remaining amount" and "remaining amount unknown". As described above, in order to perform efficient measurement, before using the sample analyzer 30 for continuous measurement, it is necessary to confirm in advance whether the reagents required for the measurement are sufficient.

[0120] In addition, the reagents used for analyzing blood coagulation and fibrinolysis are mostly sealed in small medicine bottles, not in cassettes. Therefore, reagents of the same category and the same batch can be collected in one small medicine bottle for use. For example, the following operation is performed on site: after the sample analyzer 30 is used, two reagents with half of their capacity used are transferred to one small medicine bottle for the next use. At this time, the reagent information database 36 stores the remaining amount of reagents before the sample analyzer 30 is about to be used, but the operator will not know the relevant matters related to the replenishment of the reagents by hand afterwards.

[0121] Because of this situation, it is important to measure the remaining amount before starting the continuous measurement of the sample analyzer 30. In the reagent management interface 600 displayed by the sample analyzer 30, several reagents (reagents whose reagent names and batches are known) can be selected, so several reagents can be collectively provided for the remaining amount measurement. In addition, by notifying the operator of the remaining amount measurement result, it is possible to prompt the operator to replenish the necessary reagents.

[0122] The following is based on Fig.19 The following describes a process flow when a plurality of icons 700 are selected and a plurality of corresponding reagent remaining amounts are measured.

[0123] In S51 a , an input for remaining amount measurement is accepted. This step is initiated when the operator taps the “remaining amount measurement” button in the operation instruction area 650 .

[0124] In S52a, the liquid level of the reagent stored in the reagent container 442 is detected. Specifically, the suction nozzle 451 (461) of the reagent dispensing unit 450 (460) moves downward from the initial position (height H1) for aspirating the reagent. The suction nozzle 451 (461) is driven by a stepping motor, and moves a distance D every time one pulse is input to the stepping motor. A sensor is provided at the front end of the suction nozzle 451 (461), thereby detecting the liquid level of the reagent. The number of pulses P when the sensor detects the liquid level of the reagent is also acquired by the measurement control unit 32a.

[0125] In S53a, the analysis control unit 33a calculates the liquid level (see Fig. 20). Specifically, the analysis control unit 33a receives the number of pulses P from the measurement control unit 32a. Then, the analysis control unit 33a calculates the liquid level H by the following formula (1) (H1 and D are stored in the analysis storage unit 33b as given values). H (liquid level) = H1 (height of the initial position) - P (number of pulses) × D (movement distance of 1 pulse) ... (1).

[0126] In S54a, the analysis control unit 33a calculates the reagent remaining amount from the container type and the liquid level. Specifically, the analysis control unit 33a obtains the horizontal inner area S of the reagent container 442 from the reagent information database 36. Next, the analysis control unit 33a calculates the reagent remaining amount T by the following formula (2). T (remaining amount) = H (liquid level) × S (inner area of ​​the reagent container) ... (2).

[0127] In S55a, the analysis control unit 33a stores the calculated reagent remaining amount T in the reagent information database 36. If the reagent remaining amount data is already stored in the reagent information database, the data is deleted and the reagent remaining amount T calculated in the steps of S51a to S54a is newly stored.

[0128] [Example 2: Unified editing of reagent information] In Example 2, information is edited for the reagents corresponding to the selected icons 700. Fig. 9 You can perform this operation on the icons of reagent information including "Barcode read error (no last reagent information)", "Barcode read error (previous reagent information)", "Unregistered reagent", and "Unregistered reagent batch". This example is useful, for example, when there are several unregistered batches of reagents, all of which are the same batch.

[0129] The following is based on Fig.21 The following describes a processing flow when, after selecting a plurality of icons 700 , the reagent information of the corresponding plurality of reagents is collectively edited.

[0130] In S51b, input for information editing is accepted. This step is initiated when the operator touches the "reagent information edit" button in the operation instruction area 650.

[0131] In S52b, the display control unit 51 causes the display unit 33c to display the reagent information editing area 2300. The reagent information editing area 2300 is, for example, Fig. 22 The pop-up interface is shown. Fig. 22 In the example, the information of the reagent name "PTTHS" has been read from the barcode A of the reagent container 442, and the container type, the batch number of the reagent, the expiration date, the order of use, etc. have not been set.

[0132] In S53b, information input is accepted. At this time, the operator appropriately inputs reagent information via the input unit 33d.

[0133] In S54b, the analysis control unit 33a stores the edited reagent information in the reagent information database 36. Thus, the reagent information of the plurality of reagents corresponding to the plurality of icons 700 that have been selected is updated.

[0134] [Example 3: Restoration of reagent information] In Example 3, the reagent information is restored for the reagents corresponding to the selected icons 700. Fig. 9 This operation can be performed on the icon of reagent information including "barcode reading error (previous reagent information)". For example, when the reagent container 442 has been placed on the mounting portion 441 since the last use of the sample analyzer 30, but a barcode reading error occurred before the current use of the sample analyzer 30, this operation can be performed.

[0135] The following is based on Fig.23 , the processing flow when a plurality of icons 700 are selected and the corresponding plurality of reagent information is restored will be described.

[0136] In S51c, an input for information restoration is received. This step is initiated when the operator touches the "reagent information restoration" button in the operation instruction area 650.

[0137] In S52c, the analysis control unit 33a retrieves the reagent information database 36 to obtain the required reagent information. Specifically, the analysis control unit 33a refers to the holder number of the placement section 441 corresponding to the selected plurality of icons 700. Next, the analysis control unit 33a obtains the reagent information corresponding to the holder number from the reagent information database 36. As a result, the reagents arranged at the positions of the placement sections 441 corresponding to the selected plurality of icons 700 at the time of the last use are extracted.

[0138] In S53c, the analysis control unit 33a stores the reagent information acquired in S52c in the reagent information database 36. The reagent information database 36 is thereby updated.
