Description

  The present invention relates to an automatic analyzer for measuring a component concentration of a specimen composed of blood, urine, and the like, and a screen display method for the automatic analyzer.

  In laboratories such as hospitals, clinical technologists perform analysis by putting patient specimens into automatic analyzers.

  The measurement results issued in the laboratory are reported to the doctor, and the presence or absence of the disease is determined. Depending on the type of specimen, the doctor may want to know the results immediately. For example, analysis items that are urgently requested can be reported to the doctor in real time as to how long the results are output, in addition to the measurement results.

  Further, in recent medical practice, medical cost reduction is required, and one laboratory technician often performs analysis using a plurality of types and a plurality of types of analyzers.

  It is also conceivable that an operator who is unfamiliar with the automatic analyzer due to lack of manpower will use the apparatus.

  However, the operation of current automatic analyzers is complicated due to the addition of various functions, so it takes time to operate each automatic analyzer, and there are many operation screens. It takes a long time to get used to.

  Furthermore, as the screens of automatic analyzers become more complex, various functions are scattered across multiple screen displays. To obtain the necessary information, the operator collects information by referring to multiple screen displays. It is also a problem that we have to judge comprehensively.

  Patent Document 1 discloses a screen display that allows a busy laboratory technician to check the device status at a glance by displaying alarm information and the like using a screen saver and allowing the laboratory technician to check the device status from a remote location. Yes.

  Patent Document 2 discloses a screen display that facilitates adjustment by displaying X-ray count rate information and measurement waveform information of an X-ray analyzer on the same screen as parameters for adjusting a measurement state. Has been.

JP 2006-145882 A JP 2000-35411 A

  The invention disclosed in Patent Document 1 only displays the alarm information of the device on the screen saver, and the operation after confirming the display contents and releasing the screen saver is left to the experience and judgment of the laboratory technician. Therefore, it is not convenient for an operator who is not familiar with the apparatus.

  In addition, since the entire screen is covered with a screen saver, it is not possible to simultaneously confirm a plurality of types of information, for example, alarm information of the apparatus and the measurement result of the sample at the same time.

  The invention disclosed in Patent Document 2 includes an area for displaying X-ray count rate information and dead time information on a display device of an X-ray analyzer in order to optimize measurement conditions.

  However, display of only the X-ray count rate information and dead time information is sufficient for adjustment of the X-ray analyzer. However, since automatic analyzer has a wide variety of information related to measurement, as described in Patent Document 1 If the display is simply performed on the screen, the area for displaying the measurement conditions, operation information, and the like that should be originally displayed by the display unit is reduced, and the usability is deteriorated.

  In view of the above, an object of the present invention is to provide an automatic analyzer equipped with a screen display that makes it easy for an inspection engineer to grasp information such as measurement status and device status.

  Another object of the present invention is to provide an automatic analyzer having a screen display that makes it easy to make a screen transition to the next operation to be performed from the obtained information.

  In order to achieve the above object, a configuration of the present invention includes an analysis unit that performs analysis by mixing a sample and a reagent, and a display unit that displays at least one of a measurement status and an apparatus status in the analysis unit. In the automatic analyzer, at least one of the measurement status and the device status, and information related to the item are always displayed on a part of the screen of the display unit regardless of the display screen of the display unit. It is characterized by having a control unit that controls to display the area.

  The measurement status refers to the ID number of the sample, the measurement operation such as dispensing, stirring, and analysis performed on the sample, the remaining time until the measurement result is output, and the measurement result.

  The device status refers to information on whether or not an alarm has occurred and information on the content of alarm occurrence, information on whether or not maintenance is necessary, and information on necessary maintenance content. As a result, information that the operator wants to know in a hurry is displayed in the constant display area, so that information can be acquired easily and quickly.

  Here, an operator may specify the specimen whose measurement status is always displayed in the display area. As the designation means, a dedicated screen display is provided, and it is conceivable that the operator can designate a desired specimen by using an input device such as a keyboard, a mouse, or a touch panel. As a result, the display of the specimen that the operator focuses on can be always displayed in the display area over time.

  In addition, the constant display area may be controlled so that a plurality of items are switched with time so that information on the plurality of items can be displayed. Thereby, even when there are a plurality of items to be noted, it is possible to avoid that the display area is always excessively large and occupies the display screen.

  In addition to the above configuration, another configuration of the present invention includes a storage unit that stores a related screen display that displays information related to items that are always displayed in the display area, and the control unit is requested by an operator. The related screen display is controlled to be displayed on the display unit.

  Thereby, it is possible to easily shift to the related screen display on which information to be obtained is displayed.

  According to the present invention, since the operator can easily check the current measurement status and device information if he / she always pays attention only to the display area, it is safe even for a busy operator or an unfamiliar operator. You can use the device with care.

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  The present embodiment is one of the forms of the present invention, and is not limited to this form.

  FIG. 2 is a schematic diagram of the overall configuration of the automatic analyzer. First, an outline of the automatic analyzer will be described.

  In FIG. 2, when an analysis measurement item of a sample is selected from the operation unit 201 having a display unit such as a display and an input unit such as a keyboard and a mouse, and a start button is pressed, the interface 202 starts the analysis unit 203 and starts maintenance and maintenance. An analysis control instruction or an analysis measurement request is transmitted. In the sample measurement, the analyzer rotates the reaction disk 204 according to the analysis control instruction and the analysis measurement request, dispenses the sample into the reaction container 205 using the sample dispensing probe 206, and installs the reagent probe 207. The reagent is dispensed to prepare a reaction solution, and the reaction solution is stirred by the stirring mechanism 208. Then, using the light source 209 and the multi-wavelength photometer 210, the absorbance of the reaction vessel 205 is measured, and the concentration is calculated. The reaction container 205 after the measurement result is output is cleaned by the cleaning mechanism 211. The analysis unit 203 transmits the concentration calculation result of the measured analysis item of the sample from the interface 202 to the operation unit 201. Further, the analysis unit 203 calculates the final measurement result output scheduled time of each sample from the analysis measurement request received from the operation unit 201, the operation status of each mechanism, and the current position of the sample, and the final measurement result via the interface 202. The scheduled output time and measurement status are transmitted to the operation unit 202. At the time of performing maintenance, the analysis unit 203 performs a mechanism operation according to the maintenance control instruction received from the operation unit 201. The remaining time until the end of the maintenance is calculated from the operation progress status of each mechanism, and the remaining time until the end of the maintenance and the apparatus state are transmitted to the operation unit 201 via the interface 202.

  Further, when the analysis unit 203 detects a reagent shortage or a mechanism error, the alarm information is transmitted to the operation unit 201 via the interface 202.

  The operator can check the information transmitted from the analysis unit 203 on the display of the operation unit 201 in real time.

  FIG. 1 is a screen configuration example of an automatic analyzer having a constant display area. A constant display area 102 is always displayed at the top of the automatic analyzer screen 101.

  In the example of FIG. 1, measurement information that the specimen ID is 001, the waiting time until measurement result output is 5 minutes, and the measurement data output is waiting is displayed in the constant display area 102, and the operator can display the specimen monitor screen 104. Is displayed. The sample monitor screen 104 is always displayed in an area that does not overlap the display area 102.

  As an example, the screen associated with the sample measurement information is the measurement result screen 103, and the display trigger of the associated screen is a press of the Enter key by the keyboard 212.

  When the operator selects the constant display area 102 with the mouse 213 and further presses the Enter key on the keyboard 212, the pressing of the Enter key triggers the screen guidance, the sample monitor screen 104 is automatically closed, and the constant display area 102 is displayed. The measurement result screen 103 associated with the sample measurement information being displayed is displayed in a region that does not always overlap the display region 102.

  At this time, on the measurement result screen 103, the measurement result and measurement state of the sample with the sample ID: 001 being displayed in the constant display area are initially displayed.

  The constant display area 102, the sample monitor screen 104, and the measurement result screen 103 are all displayed with a symbol ● as an icon indicating the sample ID: 001, and the operator can measure the measurement information and position of the target sample ID: 001. Information can be searched quickly and easily.

  FIG. 3 shows another example of the screen associated with the constant display area.

  The alarm screen 301 is a screen for confirming detailed information of alarm information.

  The maintenance screen 302 is a screen that displays a list of maintenance items of the apparatus and displays a maintenance execution instruction and a remaining time until the maintenance in progress is completed.

  Both the alarm screen 301 and the maintenance screen 302 are displayed by pressing a button or the like arranged in an area that does not always overlap the display area 102 at normal times.

  In the display item 402, a list of information (specimen measurement information, alarm information, maintenance information) that can be displayed in the constant display area 102 is displayed. Whether or not each information is always displayed in the display area 102 can be set by operating the display selection 403 with the mouse 213. When displaying, the display selection 403 is selected, and when not displaying, the display selection 403 is not selected.

  FIG. 4 is an example of a display parameter display setting screen in the constant display area 102 and an association setting screen for setting the association of each screen.

  The operator can perform these settings on the display setting screen 401.

  In the example of FIG. 4, the display of sample measurement information and maintenance information is valid, and the display of alarm information is invalid. Therefore, even when an alarm occurs, alarm information is not output to the constant display area 102.

  The association between the constant output unit and each screen is set on the association setting screen 407 opened by pressing the association setting button 412.

  Whether the association is valid is displayed in the association selection 405. A list of screens to be associated is displayed on the association setting screen 407.

  As the sample measurement information, one of the sample monitor screen and the measurement result screen can be selected. In the example of FIG. 4, since the measurement result screen is selected, the measurement result screen is automatically opened when the related screen display trigger is issued.

  As alarm information, one of an alarm screen, a reagent screen, and a calib screen can be selected. In the example of FIG. 4, an alarm screen is associated.

  As the maintenance information, the association to the maintenance screen can be set, but in the example of FIG. 4, the association is invalid. In this case, even if the operator operates the screen guidance trigger with the mouse 213 and the keyboard 212 while the maintenance information is being displayed in the constant display area 102, the maintenance screen is not displayed and does not overlap with the constant display area 102. The displayed screen continues to be displayed.

  When a plurality of pieces of information to be displayed in the constant display area 102 exist at the same time, an interval for automatically switching each information is set at a display switching interval 406. In the example of FIG. 4, the display switching interval can be set in three stages, and is set to a normal switching interval.

  In addition, as a method of registering the sample measurement information in the constant display area 102, a method of registering the selected sample triggered by being selected from the list on the measurement result screen 103, or displaying the sample selected in the list at all times There may be a method of registering a specimen dragged and dropped with the mouse 213 in the area 102.

  FIG. 5 is an example of automatic display switching when a plurality of display information exists in the constant display area 102. FIG. 5 shows an example in which two pieces of information, one sample measurement information and one alarm information, exist simultaneously.

  A state 502 in which the constant display area 102 displays the alarm information (reagent shortage alarm) after the set time of the display switching interval 406 has elapsed after the constant display area 102 has entered the state 501 in which the specimen measurement information with the specimen ID: 001 is displayed. Automatically switch to. Thereafter, after the set time of the display switching interval 406 elapses, the state is automatically switched to the state 503 in which the sample measurement information of the sample ID: 001 is displayed.

  The operator can grasp the measurement status and device status if he / she pays attention only to the display area 102 at all times.

  In recent years, a monitor attached to a personal computer used for an operation unit tends to be enlarged. If the constant display area 102 can be secured to a certain size, the operator can visually check the measurement status of the apparatus and the occurrence of interruption work even from a position some distance from the apparatus without using screen saver technology.

  FIG. 6 shows an example in which the display is manually switched when a plurality of display information exists in the constant display area 102. As an example, a trigger for simultaneously displaying a plurality of pieces of information is assumed to be pressing the ↓ key on the keyboard 212.

  In normal times, as in the normal display state 601, one piece of information is displayed in the constant display area 102 at a time.

  When the operator selects the constant display area 102 with the mouse 213 and further presses the ↓ key on the keyboard 212, the display size of the constant display area 102 is temporarily changed to display a multiple information batch display state 602.

  In the example of FIG. 6, three pieces of information (alarm information of a reagent shortage alarm, sample measurement information of sample ID: 001, sample measurement information of sample ID: 002) are displayed simultaneously.

  When the operator selects one piece of information on the selection bar 603, the constant display area 102 returns to the original display size, and the screen associated with the information selected on the selection bar 603 overlaps the constant display area 102. Display in the area that is not.

  In FIG. 6, since alarm information is selected, the constant display area 102 displays a reagent shortage alarm display 604 and an associated alarm screen 605. On the alarm screen 605, information related to the reagent shortage alarm displayed in the constant display area 102 is initially displayed.

  In the display of alarm information such as the reagent shortage alarm display 604, it may be possible to always display the display area 102 using symbols and colors depending on the importance of the alarm. As a result, even when the operator is away from the operation unit 201, the urgency level and importance level of the alarm can be grasped by using colors and symbols.

  FIG. 7 shows a data structure used when display processing of the constant display area is performed. Using the display candidate storage data 715 and the detailed data 721, display is always performed in the display area.

  The detailed data 721 includes alarm information detailed data 701, maintenance information detailed data 706, and specimen measurement information detailed data 710.

  The alarm information detailed data 701 stores an alarm generated in the apparatus in real time. An alarm handling state 702, an alarm code 703, an alarm name 704, and an alarm level 705 are stored. An alarm that has been handled by the operator has an alarm handling state 702, and an alarm that has not been handled has an alarm handling state 702 that is not yet handled.

  For example, when the alarm is deleted from the screen because the alarm is dealt with on the alarm screen 605, the alarm handling state 702 is updated from not yet. An alarm whose alarm handling state 702 is not yet becomes a display candidate in the constant display area 102.

  The maintenance information detailed data 706 stores a list of maintenance items executed in the apparatus and a maintenance execution state. A maintenance execution state 707, a maintenance name 708, and an ongoing maintenance remaining time 709 are stored.

  Maintenance information in which the maintenance execution state 707 is being executed becomes a display candidate in the constant display area, and the remaining time 709 of the ongoing maintenance is updated in real time based on the progress of the maintenance.

  The specimen measurement information detailed data 710 stores a list of specimens registered in the apparatus, specimen identification information, and measurement state. The display selection state 711, the specimen ID 712, the specimen measurement state 713, and the measurement result output remaining time 714 are always stored in the display area, and the sample measurement information having the display selection state 711 is a display candidate in the constant display area. .

  Data that is a display candidate in the constant display area is registered in the display candidate storage data 715. The display candidate storage data 715 stores a record number 716, a display information type 717, key information 718, a display state 719, and a display elapsed time 720.

  Based on the display information type 717 and key information 718 of the display candidate storage data 715, the detailed data to be displayed in the constant display area can be retrieved from the detailed data 721 and displayed. The data whose display state 719 is being displayed is the data currently displayed in the constant display area.

  A record in which both the display information type 717 and the key information 718 are NUL is an empty record, and new display candidate data is stored. When the display candidate data is no longer targeted, both the display information type 717 and the key information 718 are updated to NUL.

  FIG. 8 is a display processing flow of the constant display area.

  First, the display elapsed time 720 is updated by the display elapsed time update process 801 if there is data being displayed in the constant display area 102.

  Next, the record number stored in the record number 716 whose display state 719 is being displayed is stored by the record number storage processing 802.

  In the alarm information registration process 803, the maintenance information registration process 804, and the sample measurement information registration process 805, data to be registered in the display candidate storage data 715 is determined based on the contents of the detailed data 721. Data that has not been registered in the display candidate storage data 715 is additionally registered, and the data that has already been registered and is not subject to display candidate data is updated to NUL for both the display information type 717 and the key information 718.

  The presence / absence of display data is determined by the display candidate data presence / absence determination process 806. If there is no display data, the display area 811 is always displayed.

  If there is display data, the display elapsed time check processing 807 compares the updated display elapsed time 720 with the display switching interval 406. If the display switching interval 406 is exceeded, the display elapsed time 720 of the record is determined. The display state 719 is changed to undisplayed at 0 second.

  Further, the data to be displayed next is searched, and the record number 716 whose display information type 717 and key information 718 are not NUL is set as a new display record number. At this time, the display state 719 of the new display record number is changed during display. If the display switching interval 406 is not exceeded, the display record number is the same as the previous value.

  When the display record number is determined, the display update processing 809 for the constant display area searches and reads the data of the detailed data 721 from the display information type 717 and the key information 718, and updates the display of the constant display area.

  Next, in an association screen request check process 810, it is checked whether or not a screen operation for displaying the association screen from the apparatus, for example, an operation such as pressing the ↓ key on the keyboard 212 described above has occurred. .

  If there is a screen operation, an association screen display process 813 outside the constant display area is performed, and a display process of the screen set on the association setting screen 407 is performed.

  As described above, by providing a constant display area on the apparatus screen, the operating status of the apparatus can be grasped at any time in real time without a screen transition operation by paying attention to only one display area. Furthermore, by guiding to the screen associated with the constantly displayed information, it becomes possible for an inexperienced operator to easily and quickly cope with the interrupting work without hesitation in screen transition.

  Although not explained in this example, even when an interruption operation occurs due to an alarm such as expiration of a reagent, standard solution, or quality control sample, or a lot change, an interruption operation occurs in the constant display area. It is also possible to display a message indicating what to do and to guide to a screen for performing the work associated therewith. Therefore, the technique of the present invention can be applied not only during the routine but also during the preparation work of the routine.
