Description

  The present invention relates to an automatic analyzer that analyzes a test item of a sample, and relates to an automatic analyzer that can restrict an operation function accessible to the automatic analyzer according to an operator's password.

  The automatic analyzer automatically measures the concentration by reacting a component (test item) contained in a biological sample liquid such as patient-derived blood (serum, plasma) or urine with a reagent. The operation screen displayed on the user interface of the conventional automatic analyzer is displayed in a uniform screen regardless of the difference in the operator and the difference in work such as emergency inspection at night and daily work in the daytime. It is like that. Therefore, when a person who is not very familiar with the operation of the automatic analyzer, such as a nurse or doctor, performs an operation, such as a nighttime emergency test, the operation is not easy. Further, there is a possibility that an erroneous operation is performed by an operator who is not familiar with the operation of the automatic analyzer.

  In order to deal with such a problem, JP-A-1-250758 proposes to judge the level of an operator and permit use of only a specific range of functions corresponding to the level of the operator. ing. That is, in JP-A-1-250758, the operation function of the automatic analyzer is divided into analysis parameters, system parameters, registration, and maintenance, and levels are set corresponding to ID codes for each operator. If the operator inputs the ID code, only the operation function corresponding to that level is displayed on the screen. Operators are set in three levels, Advanced, Intermediate and Lower. All operations are permitted for advanced users, and only a part of operations are permitted for intermediate users. Only some of the functions are allowed.

JP-A-1-250758

  JP-A-1-250758 mentioned above teaches that only functions corresponding to the level of the operator are displayed on the screen based on the input of the operator's ID code. However, this prior art does not teach a convenient user interface configuration for the operator.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an automatic analyzer capable of overlooking the entire outline of operation functions in an automatic analyzer and easily selecting a plurality of operation function screens permitted for an operator. There is.

  Another object of the present invention is to enable an operator who has entered a password to access a higher-level operation function, and to provide an operator who has not entered the password a minimum operation function for specimen testing. It is to provide an automatic analyzer that enables access.

  The present invention is applied to an automatic analyzer that automatically analyzes a sample to obtain the concentration of a test item. The automatic analyzer determines a level corresponding to the input password and a memory for storing information obtained by grouping the operation functions into a plurality of groups, and accesses an operation function of a specific group according to the determined level. And a control unit to permit.

  The automatic analyzer of the present invention displays an area for displaying an operation function selection button corresponding to each group in an operation function grouped into a plurality of groups, and an operation function screen corresponding to the selected operation function selection button. And a control unit that controls the operation function selection button corresponding to the permitted group based on the determination of the level to be accessible and permits the display. The operation function selection buttons corresponding to the groups that are not set are controlled to be inaccessible.

  In a preferred embodiment according to the present invention, the operation function selection buttons corresponding to the groups permitted based on the determination of the level and the operation function selection buttons corresponding to the groups not permitted are displayed in different display colors. Is done. If there are multiple operation function screens related to the selected operation function selection button when the operation function selection button corresponding to the permitted group is selected, the multiple operation function screens are displayed in a hierarchical state. The In the hierarchized state in this case, a screen corresponding to the lowest-level operation function among the plurality of operation function screens is displayed on the surface. In addition, when the password is not input after the power to the analyzer is turned on, the control unit performs control so that only the operation function selection buttons necessary for the examination of the emergency sample can be accessed.

  According to the present invention, it is possible to overlook the entire functions that can be operated from the entire operator in the automatic analyzer, and display the screens of a plurality of operation functions permitted for the current operator at each level of operation. Can be easily selected. In addition, an operator who has entered a password can access an advanced operation function, and an operator who has not entered a password can have access to the minimum operation function for specimen testing.

  Hereinafter, an automatic analyzer according to an embodiment of the present invention will be described with reference to FIGS. In this preferred embodiment, the automatic analyzer can execute a sample analysis operation according to the contents input through the displayed operation function screen, and display the analysis result of each test item on the display device. This automatic analyzer can be operated by beginners unfamiliar with the operation of analyzers such as doctors and nurses when an emergency inspection is required at night, while the person in charge of the laboratory is in charge. The user interface is easy to handle even for an operator who is familiar with the operation of the analyzer.

FIG. 1 shows the overall configuration of the automatic analyzer. A number of reaction vessels 12 made of a translucent material are mounted along the circumference of the reaction disk 10 provided so as to be intermittently rotatable. The reaction vessel 12 is maintained at a predetermined temperature (for example, 37 ° C.) by the thermostatic chamber 14. The temperature of the fluid in the constant temperature bath 14 is adjusted by the constant temperature maintaining device 16.

  A large number of sample cups 22 containing biological samples such as blood or urine are placed on the sample disk 20. A pipette nozzle 26 attached to the movable arm 24 sucks a predetermined amount of sample from the sample cup 22 positioned at the suction position of the sample disk 20, and the sample in the reaction container 12 at the discharge position on the reaction disk 10. To discharge.

  A plurality of reagent bottles 32A and 32B with labels indicating reagent identification information such as barcodes are placed on the reagent disks respectively disposed in the reagent cold storages 30A and 30B. These reagent bottles contain reagent solutions corresponding to analysis items that can be analyzed by the analyzer. The barcode reader attached to each reagent cooler 30A, 30B reads the barcode displayed on the outer wall of each reagent bottle at the time of reagent registration. The read reagent information is registered in the memory 56 described later together with the position on the reagent disk.

  The reagent pipette nozzles in the reagent dispensing mechanisms 36 </ b> A and 36 </ b> B inhale the reagent liquid from the reagent bottle corresponding to the inspection item positioned at the reagent receiving position on the reaction disk 10 and discharge it into the corresponding reaction container 12. The mixture of the sample and the reagent accommodated in the reaction vessel 12 is stirred by the stirring mechanisms 38A and 38B.

  The rows of reaction vessels 12 are rotationally moved so as to pass through a photometric position sandwiched between the white light source 40 and the multi-wavelength photometer 42. The reaction liquid of the sample and the reagent in each reaction vessel 12 is photometrically measured while the reaction disk 10 is rotating. The analog signal measured for each sample is input to the A / D converter 44. The reaction container cleaning mechanism 18 disposed in the vicinity of the reaction disk 10 allows the reaction container to be used repeatedly by cleaning the inside of the used reaction container 12.

  Next, a control system and a signal processing system in the analyzer of FIG. 1 will be briefly described. The computer 50 is connected to the sample dispensing control unit 28, the reagent dispensing control unit 39, and the A / D converter 44 via the interface 52. The computer 50 sends a command to the sample dispensing control unit 28 to control the sample dispensing operation. The computer 50 also sends a command to the reagent dispensing control unit 39 to control the reagent dispensing operation. The photometric value converted into a digital signal by the A / D converter 44 is taken into the computer 50.

  Connected to the interface 52 are a printer 54 for printing, a memory 56 as a storage device, a floppy (registered trademark) disk drive 58, a keyboard 60 for inputting operation commands and the like, and a CRT display 100 for screen display. Has been. As the screen display device, a liquid crystal display or the like can be employed in addition to the CRT display. The memory 56 is configured by, for example, a hard disk memory or an external memory. The memory 56 stores information such as a password for each operator, a display level for each screen, analysis parameters, analysis item request contents, calibration results, and analysis results.

Next, a sample analysis operation in the automatic analyzer of FIG. 1 will be described. Analysis parameters relating to items that can be analyzed by the automatic analyzer are previously input via an information input device such as the keyboard 60 and stored in the memory 56. The operator selects an inspection item requested for each sample using an operation function screen described later. At this time, information such as a patient ID is also input from the keyboard 60. In order to analyze the specified inspection item for each sample, the pipette nozzle 26 dispenses a predetermined amount of sample from the sample cup 22 to the reaction vessel 12 according to the analysis parameters. The reaction container that has received the sample is transferred by the rotation of the reaction disk 10 and stops at the reagent receiving position. The pipette nozzles of the reagent dispensing mechanisms 36A and 36B dispense a predetermined amount of reagent solution into the reaction vessel 12 according to the analysis parameter of the corresponding inspection item. The dispensing order of the sample and the reagent may be reversed from this example, and the reagent may precede the sample.

  Thereafter, the sample and the reagent are stirred and mixed by the stirring mechanisms 38A and 38B. When the reaction vessel 12 crosses the photometric position, the multiwavelength photometer 42 measures the absorbance of the reaction solution. The photometric absorbance is taken into the computer 50 via the A / D converter 44 and the interface 52. This absorbance is converted into concentration data based on a calibration curve measured in advance by an analysis method designated for each inspection item. Component concentration data as an analysis result of each inspection item is output to the screen of the printer 54 or the CRT 100.

Before the above measurement operation is executed, the operator sets various parameters necessary for analysis measurement and registers the sample via the operation screen. In addition, the operator can use the CRT
Confirm with the operation screen on 100.

  Next, an example of an operation screen that can be displayed on the CRT of the automatic analyzer according to the present embodiment and the relationship between each level will be described with reference to FIG. FIG. 2 shows the relationship between the types of operation screens that can be displayed on the CRT display 100 and the levels permitted for the operator. The operation functions related to the automatic analyzer are grouped into a plurality as shown in A to E of FIG. 2, and information on these operation function screens is stored in the memory 56. Whether or not each operation function screen can be displayed is controlled by the computer 50.

  As shown in FIG. 2, the types of screens corresponding to the overall operation functions for the automatic analyzer are the routine screen A, the reagent management screen B, the accuracy management screen C, the calibration screen D, and the utility screen E. It is classified into each group. The operation function of each group receives an instruction via one or more operation function screens and is executed under the control of the computer 50 as a control unit.

  The routine screen A in FIG. 2 includes a patient sample request screen A1, a patient sample measurement result screen A2, and an initial setting screen A3. The utility screen E includes a maintenance / inspection screen E1, an analysis parameter setting screen E2, and a system parameter setting screen E3.

  Here, the contents of each screen will be described.

  The patient sample request screen A1 in the routine screen A is a screen for selecting and registering test items for each sample derived from each patient. The patient sample measurement result screen A2 is a screen that displays measurement data for each patient for confirmation by the operator. The initial setting screen A3 is a screen used for setting conditions for the analyzer at the start of analysis and instructing a preparation operation.

  The reagent management screen B is a screen used for checking the remaining amount of the reagent in each reagent bottle and for newly registering the reagent. The accuracy management screen C is a screen for displaying a monitoring result in which conditions for monitoring the presence / absence of abnormality of the measurement data or the deterioration state of the reagent can be set. The calibration screen D is a setting screen for performing calibration by reacting a standard sample or a calibrator with a reagent.

  The maintenance / inspection screen E1 in the utility screen E is a screen used when setting conditions for executing maintenance of the apparatus and displaying stored data as a result of periodic maintenance operations. The analysis parameter setting screen E2 is a screen for setting parameters as analysis conditions to be stored for each item that can be analyzed. The system parameter setting screen E3 is a screen for setting a sample type, system interface connection information, a password for each operator, and the like.

  There are various levels of operators of automatic analyzers, from beginners who are unfamiliar with the handling of equipment, such as doctors and nurses, to those who are familiar with the handling of equipment, such as laboratory managers. To do. Therefore, in the present embodiment, the operation functions that can be accessed by these operators are classified into four levels of level 1 to level 4. Among these, for example, level 1 is only an operation function required when a beginner who does not normally operate an automatic analyzer such as a doctor or a nurse uses an automatic analyzer in an emergency examination at night. Including. Level 2 includes an operation function required when a laboratory engineer operates the analyzer in a daytime hospital or the like, or when a laboratory administrator uses the analyzer to check data. In addition to the functions of level 1 and level 2, level 3 also includes functions required when an experienced laboratory technician changes analysis parameters related to reagents and the like. In addition to the functions of levels 1 to 3, level 4 includes functions required when a service engineer or a laboratory manager uses the analyzer. In other words, level 4 provides access to all operating functions of the analyzer.

  Next, the relationship between the displayable operation screen and each level will be described.

  For example, doctors and nurses usually have few opportunities to use automatic analyzers, so if an analyzer displays an unnecessary screen during an emergency test, it will not be possible to perform an emergency specimen test smoothly and will be operated incorrectly. Fear also arises. On the other hand, the manager in charge of the laboratory needs to set system parameters and the like, but system parameters are matters that are not easily changed by anyone other than the manager.

  Based on this situation, the accessible screens are limited for each level except level 4.

  As shown in FIG. 2, for an operator who needs only the level 1 operation function, the control unit of the analysis apparatus displays only the operation function screen of the group of the routine screen A on the CRT display 100 as a display device. That is, the patient sample request screen A1, the patient sample measurement result screen A2, and the initial setting screen A3 are displayed. As a result, the operator can perform the minimum input setting for sample analysis by using these operation function screens. For example, when an emergency test is necessary, a doctor or a nurse can make an emergency sample test request to the automatic analyzer using the level 1 function, and obtain a measurement result related to the sample. In this case, the use of the functions of levels 2 to 4 is not permitted by the control unit.

  In level 2, in addition to the screens A1, A2, and A3 of the routine screen A, the control unit performs maintenance and inspection screens among the reagent management screen B, the accuracy management screen C, the calibration screen D, and the utility screen E. E1 is allowed to open on the screen of the CRT display and is controlled so that the operator can access these operation function screens. However, as will be described later, in the case of level 2, regarding the maintenance / inspection screen E1, not all of the included operation functions are released, and the use of some operations is restricted.

  In level 3, in addition to all operation function screens related to the routine screen A and B, C, and D screens, the control unit displays a maintenance inspection screen E1 and an analysis parameter setting screen E2 in the utility screen E. Opening to the screen of the CRT display is permitted, and the operator can access these operation function screens. That is, at level 3, all operation function screens except the system parameter setting screen E3 in FIG. 2 can be accessed.

  At level 4, the control unit permits the system parameter setting screen E3 to be opened on the screen of the CRT display in addition to all the operation function screens permitted for levels 1 to 3, and the operator selects the screen shown in FIG. It is possible to access all operation function screens. For example, the person in charge of the examination room is permitted by the control unit to access the system parameter setting screen E3, but since others are assigned levels 1 to 3, other persons change the system parameters. Can not.

  Next, the flow of processing when displaying the operation function screen in the automatic analyzer according to the present embodiment will be described with reference to FIG.

  In step 300, when the automatic analyzer is turned on, the screen display process starts. In step 310, the computer 50 as the control unit shown in FIG. 1 displays an operator name and password input screen on the CRT 100. The operator name and password are registered in the memory 56 in advance using the system parameter setting screen E3.

  In step 320, the computer 50 determines whether or not an operator name and a password have been input. If they are input, the process proceeds to step 330. If not, the process proceeds to step 340. Here, the case where the operator name and password are not input is, for example, a case where an examination of an emergency sample is required. Due to the urgency of an emergency test, the automatic analyzer can perform the minimum operation functions (request for an urgent sample and display of the measurement results) without entering the operator name and password. Operation controlled. Such an operation function corresponds to level 1 in FIG. The determination of whether or not the operator name and password are input is made based on a mode in which a password or the like is not input within a predetermined time, or a mode in which an instruction button for accessing level 1 without a password is provided.

  When no password or the like is input in step 320, the control unit displays an operation function selection screen as shown in FIG. 4 to be described later on the CRT display, and an operation function for instructing the screen display of the operation function corresponding to level 1 Control is performed so that only the selection button 110 can be accessed. Thereby, the analysis operation necessary for the examination of the urgent sample is executed by the automatic analyzer.

  When the operator name and password are input, in step 330, the computer 50 confirms a match with the operator name and password registered in the memory 56, and then is permitted to the operator. Determine.

  In step 340, the control unit permits access to the operation function of the specific group according to the determined level. That is, the computer 50 displays the operation function selection screen on the CRT display, and controls the access to the selection buttons provided corresponding to the respective operation function groups A to E, thereby achieving the level. The screen display is controlled so that the corresponding operation function screen can be opened. Specific contents of such a screen display will be described later with reference to FIGS.

Next, in step 350, the computer 50 receives an input from the display screen or an input from the keyboard 60, and executes a process according to the input. Thereafter, the process returns to step 310 to display an input screen such as a password and waits until the next input.

  Next, a display example of an operation screen that can be used by an operator who is permitted only to use the level 1 operation function in the automatic analyzer of FIG. 1 will be described with reference to FIG.

  When the process proceeds to step 340, a plurality of operation function selection buttons 110, 120, 130, 140 and 150 in the screen of FIG. 4 are displayed on the screen of the CRT display 100. A1, A2 and A3 are not displayed yet. These operation function selection buttons are displayed regardless of whether the password is input by the operator or not, but the selection buttons that can be accessed by the operator differ depending on the level. In the case of level 1, B to E exist as operation function groups that are not permitted to access, but the control unit prevents the selection buttons 120, 130, 140, and 150 corresponding to these groups from being accessed. Be controlled.

  In the screen of FIG. 4, an area for displaying a selection button corresponding to each of a plurality of operation function groups is formed on the upper side in the screen, and an area for displaying an operation function screen corresponding to the selected selection button is displayed. It is formed on the lower side in the screen.

  Of the five operation function selection buttons, the button 110 is a button for instructing to display the routine screen A. By selecting the button 110 using the keyboard 60 or the mouse, the routine screen A is selected. The patient sample request screen A1, the patient sample measurement result screen A2, and the initial setting screen A3 can be displayed. A plurality of lower-level operation function screens A1, A2, A3 related to the operation function group A are displayed in a hierarchical state. The patient sample request screen A1 that is most necessary for the operator appears on the uppermost surface layer. On the second layer, the patient sample measurement result screen A2, which is most necessary next, is displayed in a hidden state so that only the tag 114 can be seen. In the lowest layer, the initial setting screen A3 is displayed in a state where only the tag 116 is shown and hidden.

  These lower screens can be selected in a form format, and by selecting any of the tags 112, 114, or 116 as the instruction buttons of the individual operation function screens, the screens A1, A2 are selected. Alternatively, a screen corresponding to the selection from A3 appears on the top layer. In the state shown in FIG. 4, the tag 112 is selected, and the patient sample request screen A1 is displayed. In the patient sample request screen A1, a column 112A for inputting a sample number and a plurality of examination item selection buttons 112B are displayed. If the number of inspection items is large, the list of inspection items can be in a form of a plurality of forms.

  Therefore, when testing an urgent sample, the sample number can be entered in the input field 112A and the test item can be selected for each sample sequentially from the series of selection buttons 112B. Request operations can be performed.

  A button 120 in FIG. 4 selects an operation function group on the reagent management screen B, a button 130 selects a group on the accuracy management screen C, and a button 140 selects a group on the calibration screen D. The button 150 is used to select a group on the utility screen E. By the way, it is restricted that an operator who is permitted only level 1 cannot access the selection buttons 120, 130, 140, and 150 other than the selection button 110. The operation function selection button corresponding to the group permitted to access according to the level and the operation function selection button corresponding to the group not permitted to access are displayed in different display colors. In the case of level 1, specifically, the buttons 120 to 150 displayed by broken lines are displayed in gray, for example, and the accessible button 110 is highlighted, and an accessible screen and an inaccessible screen are displayed. Are visually distinguished. For example, even if an operator who is permitted only level 1 tries to select the button 120, the reagent management screen B corresponding to the button 120 is not displayed.

  When analyzing an emergency sample corresponding to level 1, a nurse or doctor who is a beginner inputs a sample number and selects a test item using the patient sample request screen A1. Further, the sample set position (sample disk number and position) is input. When the analysis operation is executed and the examination is completed, the patient data can be confirmed after confirming the sample number using the patient sample measurement result screen A2. That is, since an emergency sample can be analyzed only by operating the patient sample request screen A1 and the patient sample measurement result screen A2, even those who are unfamiliar with the operation of the automatic analyzer can be easily operated. Further, since unnecessary screens cannot be accessed, there is no erroneous operation, and the reliability of the obtained measurement data is improved.

  Next, a display example of an operation screen that can be used by an operator who is permitted to use the level 2 operation function in the automatic analyzer of FIG. 1 will be described with reference to FIG.

  If the determination in step 330 of FIG. 3 is level 2, the operator adds the reagent management screen B, the accuracy management screen C, and the operation function screens A1, A2, and 3A below the operation function group A. The control unit is allowed to access the calibration screen D. Further, at level 2, the operator is permitted to partially access the maintenance / inspection screen E1, which is a lower screen of the utility screen E. However, access to the analysis parameter setting screen E2 and the system parameter setting screen E3 is not permitted. Therefore, at step 340 in FIG. 3, the plurality of operation function selection buttons 110, 120, 130, 140, 150 displayed on the upper area of the screen by the CRT display 100 are as shown by the solid lines in FIG. The highlight display means that access is possible.

By selecting the operation function selection button 150 corresponding to the group on the utility screen E in step 350 of FIG. 3, a plurality of lower-level operation function screens related to this button 150 are displayed in a hierarchical state. However, in the case of level 2, since access to only the maintenance inspection screen E1 in the utility screen is permitted, the analysis parameter setting screen E2 and the system parameter setting screen E3 include portions of tags 154 and 156. Except for this, it is hidden by the maintenance inspection screen. In level 2, the tag 152 on the maintenance inspection screen E1 that can be accessed is highlighted as shown by the solid line in FIG. 5, but the tag 154 and system parameter setting on the analysis parameter setting screen E2 that is not allowed to be accessed. The tag 156 on the screen E3 is displayed in gray as indicated by a broken line in FIG.

  The utility screen E has a plurality of lower-level operation function screens, and the hierarchical order of these lower-level screens is a function whose level is higher in order from the upper layer to the lower layer. That is, the operator who is permitted level 2 can access the maintenance inspection screen E1 of the uppermost layer, and the analysis parameter setting of the second layer is made for the operator who should be permitted level 3. Access to the screen E2 is permitted, and access to the system parameter setting screen E3 in the lowest layer is permitted for an operator who should be permitted level 4. An operator who is permitted an advanced-level operation function can open a corresponding lower-level operation function screen in the uppermost layer by selecting the tag 154 or 156.

  Thus, since the operator determined to be level 2 cannot access the analysis parameter setting screen E2 and the system parameter setting screen E3, these settings are not erroneously changed.

  Next, with reference to FIG. 6, a description will be given of a restriction example in the case where an operator who is permitted level 2 uses the operation function screen.

  The maintenance inspection screen E1 in the utility screen group can be accessed by each of the operators from level 2 to level 4. However, some of the maintenance inspection screens may or may not be accessible according to the level of the operator. I try to divide it into possible ones. That is, for example, among the operation functions for daily accuracy management included as one of the lower-level functions of the maintenance inspection screen, the management data is any of the operators permitted for level 2, level 3 and level 4. However, the deletion of management data and the accumulation of management data cannot be accessed by level 2 operators, but can be accessed by level 3 and level 4 operators. By doing so, it is possible to prevent the level 2 operator from deleting the management data by mistake.

  On the other hand, an operator who is permitted level 3 can also manage reagents and calibration. Analysis parameters and other settings have specialized knowledge such as reagent amount, wavelength, photometry point designation, alarm generation level designation, calibration result judgment, etc., so measurement by accessing those without such knowledge There is no loss of data reliability.

  The level setting accessible to the operator can be performed by the person in charge of the laboratory using the system parameter setting screen. The password assigned to each operator can also be registered using the system parameter setting screen E3, and only the person corresponding to the level 2 to 4 holds the password to prevent unauthorized use by a third party. To do. The password can also be changed using the system parameter setting screen E3.

  As described above, according to the present embodiment, by setting the level of the operator in advance and limiting the accessible screens according to each level, the operation for beginners and the like is facilitated, and there is no erroneous operation. . As described above, in the automatic analyzer, a screen that clarifies which operation functions of each function can be accessed by each operator and hierarchizes a plurality of lower screens belonging to the operation function group selected by the operator. By providing the user interface having the configuration, the operability is improved and the reliability is improved.
