Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an analyzer used for various tests such as clinical tests such as blood tests and urine tests, and tests in the industrial field such as quality tests of toners and pigments. , An analyzer provided with a display device for performing various displays.

[0002]

2. Description of the Related Art Among the various analyzers described above, for example, in a blood analyzer, a basic measurement item is
Five items are known: white blood cell count (WBC), red blood cell count (RBC), platelet count (PLT), hemoglobin amount (HGB), and hematocrit value (HCT). Also, the mean red blood cell volume (MCV) calculated from these data,
The mean red blood cell hemoglobin amount (MCH) and the mean red blood cell hemoglobin concentration (MCHC) may be added to the measurement items to measure a total of eight items. The electric resistance method and the light scattering method are well known as methods for measuring blood cells of WBC, RBC, and PLT. For example, in the electrical resistance method, a minute amount of a blood sample is supplied to a detector, that is, a micropore (rectifier element having a function as an orifice) in which an electric current is flown, and an impedance change generated when passing through the micropore. Is detected to obtain the number of particles such as blood cells and the particle size distribution. As a method of measuring HGB, a method of measuring the absorbance of a blood sample subjected to hemolysis is used. It is well known that a method of measuring HCT is obtained by processing an RBC measurement signal.

Among WBC, RBC and PLT blood cell measurements, RBC is about 4 million cells / μl in a normal sample,
Is a single digit difference of about 200,000 cells / μl, and the size of blood cells is different, so that the same sample can be simultaneously measured. However, WBC is 5000 in normal specimen / μ
The number of cells is about 3 digits smaller than RBCs, and the number of blood cells is almost the same as red blood cells.
It is difficult to measure the same sample at the same time. Therefore, in the WBC measurement, a sample obtained by hemolyzing red blood cells is used.

Also, in consideration of a case where a sufficient amount of blood cannot be obtained because a sufficient amount of blood cannot be obtained in a child or the like, or when a sample having an abnormally large number of blood cells is measured, a normal measurement mode (measurement in this mode (Whole blood mode measurement)
In addition to this, the blood is diluted to increase the amount of the sample, then the measurement is performed, and after the measurement, the dilution measurement mode in which the increase in the amount is corrected by calculation processing (the measurement in this mode is referred to as the dilution mode measurement) can be executed. A blood analyzer is used. As described above, as a blood analyzer capable of performing measurement in a plurality of measurement modes, there can be mentioned XE-2100 manufactured by Sysmex Corporation.

In addition, in preparation, a constant volume flow path is used to perform a fixed amount of plural high-viscosity samples such as blood samples in a number corresponding to the number of measurement processes and perform a dilution process at a predetermined dilution ratio. , A pipette, a sampling valve composed of an electromagnetic valve, a mix chamber for preparing a blood sample, etc. are used, and a sensor for monitoring is attached to these as necessary, or the operating time is set by a timer. I'm measuring. When a sensor or the like detects an abnormality or when the operation is not completed within a fixed time, an alarm is issued to inform the measurer that a trouble has occurred.

Further, some blood analyzers and other various analyzers use a touch panel type input / display device that can perform an input operation and an output display from the viewpoints of downsizing of the device and improvement of operability. The touch panel has a pressure-sensitive sensor attached to a screen made of liquid crystal or the like. Then, an icon such as a button is displayed in a specific area on the screen, and when the measurer touches the area where the icon is displayed, the pressure-sensitive sensor corresponding to the specific area senses it and emits a signal. It has become. Some analyzers equipped with such a touch panel type input / display device display a start button on the screen for starting an operation for measuring a sample. In such an analyzer, a trouble occurs in any part of the analyzer, and the measurement operation for the next sample cannot be started as it is, or it is not preferable to start the measurement operation (these are referred to as “unmeasurable” state). ), There is also something to control the input is invalid even if you touch the start button.

[0007]

When performing measurement using an analyzer using a display device, the measurer must check the output information on the screen displayed on the display device and perform the necessary input operation. Become. Therefore, if the information displayed on this screen is mistaken, it may lead to an erroneous operation or an erroneous determination.

As the output information, the measurement result of each blood measurement item is displayed on the display screen of the input / display device.
In the blood analyzer capable of measuring all eight items, all eight items are displayed on the measurement result display screen having a limited area. In this case, the characters are displayed in a small character size, which makes it difficult to see the screen and makes it easy to read the data. Furthermore, if too many items are displayed, it is difficult for the measurer to read the important items.

Also, after these measurement results are displayed,
After the preparation process for the next measurement (cleaning process etc.) is completed,
The next analysis is started by returning the measurement result display screen to the main screen, that is, the screen on which the start button is displayed, and performing the input operation to start the measurement. You have to perform an operation to switch from the display screen to the main screen.

Further, as described above, when the control by which the input by the start button is made invalid as a result of the trouble occurring in any part of the analyzer, it is not noticed that the measurement is impossible. There was a case where the measurer repeatedly pressed the start button displayed on the screen many times despite the invalid input (so-called "empty push"). If the number of such blank pushes becomes excessive, the touch panel is overloaded, which causes a failure.

Therefore, an object of the present invention is to provide an analyzer for displaying a display for preventing the operator from making an erroneous operation or an erroneous judgment.

It is another object of the present invention to prevent an erroneous operation of starting a measurement in an erroneous mode selection in an analyzer capable of selecting a measurement mode.

It is another object of the present invention to provide an analyzer which prevents the measurement from being started when a trouble affecting the measurement result occurs and reduces the load on the touch panel as much as possible.

Further, when the measurement screen is displayed, the contents of the display are devised so that the analysis result can be easily seen according to the needs of the measurer, and the operation of the continuous measurement is simplified. To aim.

[0015]

SUMMARY OF THE INVENTION The present invention, which has been made to solve the above-mentioned problems, has a measurement mode selecting section for selecting a measurement mode in an analyzer capable of operating in a plurality of measurement modes. A start button for inputting a command to start the measurement operation in the measurement mode, a color changing section for changing the color of the start button, and a color changing section for changing the color of the start button according to the selected measurement mode. And a color change control unit for controlling.

According to the present invention, the measurement mode selecting means,
For example, in an analyzer in which the measurement mode can be selected and executed by the measurement mode selection button, the color of the start button changes according to the measurement mode selected by the measurer. With this, when the start button is pressed to start the measurement, the measurement mode can be confirmed by the color display, so that the erroneous operation due to the mode selection error can be reduced.

The analysis device of the present invention made to solve the above-mentioned problems is an analysis device having a control section, input means, and display means, in which the display means is in a state where measurement can be started. The main screen and the measurement screen for displaying the measurement result after the start of measurement are displayed, and after the measurement result is displayed on the measurement screen, the uninput state by the input means continues until the predetermined state of the analyzer occurs. Then, the control unit controls to switch the measurement screen displayed by the display unit to the main screen.

According to the present invention, the measurement is started by touching the start button when the main screen is displayed, and the measurement screen is displayed. When the measurement is completed, the cleaning process starts, but during that time, the measurement result is displayed on the measurement screen. Then, if an input operation is not performed before a predetermined state of the analyzer such as the end of the washing process, the main screen is automatically switched to simplify the labor for the operator to switch the screen one by one. When an input operation is performed, the operation is manually returned to the main screen so that the screen can be switched according to the wishes of the measurer.

Further, in the analyzer of the present invention made to solve the above problems, output information is displayed on the screen, and when a specific position on the screen is touched, an input associated with the specific position is performed. An analysis device using a touch panel type input / display device called an analysis device,
It has a monitoring means for monitoring the equipment driven in the analyzer, and the monitoring means influences the measurement when displaying the main screen on which the start button for starting the measurement is displayed on the input / display device. When an abnormality is detected, a control unit for controlling the display of the start button on the screen is erased.

According to the present invention, the analyzing device is adapted to monitor the operation of the equipment driven in the device by the monitoring means. This monitoring means measures various sensors (panel open / close sensor, pipette position sensor, sample detection sensor, sample adapter detection sensor, float switch, pressure sensor, etc.) mounted in the apparatus and processing time of programs. Includes a timer with a built-in controller. When the monitoring means detects an abnormality that affects the measurement,
Prevent the start button from appearing on the main screen where the start button is displayed. This prevents the measurer from accidentally starting the measurement because the start button is not displayed. Further, since the start button is not displayed in the first place, the start button is not pressed any more, and the load on the touch panel is reduced.

In addition, the analysis device of the present invention made to solve the above-mentioned problems has a display means for displaying a measurement screen showing the measurement results and the measurement results for one or more measurement items in the first character size. The control unit displays a first measurement screen to be displayed and a second measurement screen to display measurement results for a larger number of measurement items than the first measurement screen in a second character size.

According to the present invention, the analysis device has the first measurement screen for displaying the measurement results for one or more measurement items in the first character size, and the measurement for more measurement items than the first measurement screen. And a second measurement screen displaying the result in the second character size. For example, in an analyzer capable of displaying a maximum of eight measurement items at a time due to the display space and other factors, five particularly important items are displayed on the first measurement screen, and all eight items including the five items are displayed on the first measurement screen. 2 Display on the measurement screen. At this time, since the number of items to be displayed on the first screen is smaller than that on the second screen, the character size can be displayed larger than that on the second screen. This makes the data easier to see on the first screen, and reduces the possibility that the measurer will read the data of the important item.

Further, the control unit may be configured so that the measurement items displayed on the first measurement screen can be arbitrarily set.
As a result, it is possible for the measurer to select the items he or she considers important and to display them in a large character size, which enables display according to the wishes of the measurer.

The output signals from 3 are A / D converted and output to the control unit 500.

The control section 500 receives the output signal from the drive circuit section 501 and the output signal from the touch panel 3b, and processes these signals by a predetermined processing program.
Then, based on the processing result, the control unit 500 causes the drive circuit unit 501 to control the pipette vertical motor 405, the pipette front / back motor 205, the syringe pump motor STM4.
Syringe pump motor STM5, negative pressure pump P1, drainage pump P2, air pump P3, electromagnetic valves SV1 to SV
n is driven, the liquid crystal display 3a is caused to display, and the printer section 11 is made to print out.

Then, the control unit 500 displays various display screens on the liquid crystal display 3a based on the information stored in the ROM using a predetermined program stored in the ROM. Among these various display screens, a main screen on which a start button for starting the measurement is displayed, a mode selection screen on which the mode selection button is displayed, a setting screen for setting measurement items, and the like are included. The main screen (FIG. 4 (a), FIG. 5, FIG. 6) of this embodiment is designed so that the start button and the mode selection button are displayed at the same time.

The analysis operation of the blood analyzer will be described below with reference to the flowchart of FIG. 3, and at the same time, the transition of the screen displayed on the input / display device 3 will also be described with reference to FIG. As shown in FIG. 3, first, the blood analyzer is turned on (s1), and when a predetermined preparation time elapses (s
2), the main screen including the characters "standby" on the liquid crystal display 3a of the input / display device 3 (Fig. 4 (a))
Is displayed. This main screen includes a mode selection button and a start button.

Then, the measurer attaches the sample container containing the sample to the sample setting section 6 (s4). Next, the measurer selects whether to perform the measurement in the whole blood mode or the dilution mode (s5). Selection is made by touching any of the mode selection buttons on the main screen. When the sample in the attached sample container is a whole blood sample (a sample when performing a normal measurement), the measurer is displayed in red in the main screen displayed on the input / display device 3. Touch the "Whole blood mode" button, and if it is a diluted sample, touch the yellow "dilution mode" button (s
5).

At this time, when the "whole blood mode" button is touched, the start button in the main screen becomes red, and when the "dilution mode" button is touched, the start button becomes yellow.
At this time, the control unit 500 controls the color change unit 500a that changes the color of the button and the color change control unit 50 that controls the color change unit.
It is functioning as 0b.

Subsequently, the start button is touched while confirming the measurement mode from the color of the start button displayed on the main screen (s6). The control unit 500 determines which of the "whole blood mode" and the "dilution mode" is selected, and starts the processing of the program corresponding to each (s).
7).

When the control unit 500 receives an abnormal signal from any of the devices in the apparatus and determines that the abnormality affects the measurement, the start button on the main screen is erased. , I'm trying not to accidentally touch the start button.

Here, almost simultaneously with the start of the measurement operation based on the input from the start button, the input / display device 3
The screen displayed by is switched from the main screen (FIG. 4A) to the measurement screen (FIG. 4B). Measurement items are displayed on the measurement screen at this time, but the measurement results of each item are not displayed because they have not been obtained yet. In addition, the measurement items displayed at this time are five items (WBC, RBC, HG) that are generally said to be important by default.
B, HCT, PLT).

When the "whole blood mode" is selected,
An RBC measurement sample and a WBC measurement sample are prepared from whole blood (s8, s9). When the "dilution mode" is selected, the RBC measurement sample and the WBC measurement sample are prepared from the diluted blood (s16, s17).

Subsequently, the W prepared in step 9 (s9)
The WBC and HGB (hemoglobin concentration) measurements are performed using the BC measurement sample (s10), and when the measurement results are obtained, the data of the measurement results of these two items are first displayed on the currently displayed measurement screen (Fig. 4 (c)) (s11).

Further, R prepared in step 8 (s8)
RBC was measured using the BC sample (s12), P
LT (platelet count), HCT (hematocrit value) and other measurement items are calculated (s13), and the measurement results and the calculation results are displayed on the measurement screen (s1).
4). At this time, the measurement results of five items are displayed on the measurement screen in a large character size (FIG. 4 (d)).

Then, cleaning is started to prepare for the next measurement (s15). It is monitored whether the touch panel operation for displaying 8 items is performed during washing (s18), and when the input operation for displaying 8 items is performed, the screen moves to the 8 item display screen (FIG. 4 (e)) having a small character size (s19). . Once the screen moves to the 8-item display screen (FIG. 4 (e)), the 8-item display is displayed until the "return" button displayed on the upper right of the screen is touched (s20). Touching the “Return” button switches to the main screen (FIG. 4A) (s21). If no input operation is performed in step 18 (s18), the 5-item display screen (FIG. 4 (d)) is continuously displayed and the completion of cleaning is waited (s22).

When cleaning is completed, the main screen (Fig. 4
(A)) is switched (s21), and step 3 (s) is performed again.
Return to 3) and prepare for the measurement of the next sample. That is, when the operation for displaying the eight items is not performed before the cleaning is completed, it is determined that the eight items are not necessary to be displayed, and the screen automatically switches to the main screen (FIG. 4A). When determining whether or not to automatically switch to the main screen (FIG. 4A), the control unit 500 needs to determine whether or not the cleaning is completed. In this embodiment, the control unit 50
0 determines the end of cleaning by a signal from a sensor or the like provided in each part of the analyzer. In addition, a separate timer is provided,
When a certain period of time has passed from the start of washing, it is considered that the washing has ended, and the 5 item display screen (Fig. 4) is automatically displayed as described above.
It is also possible to configure the control unit 500 to switch (d)) to the main screen (FIG. 4A). In addition, when a certain time has elapsed from the time when it is determined that the cleaning is completed, control is automatically performed to switch the 5-item display screen (FIG. 4 (d)) to the main screen (FIG. 4 (a)) as described above. It may be configured to be controlled by the section 500.

Next, the display contents of the main screen and the measurement screen will be described. Main Screen FIGS. 5 and 6 are diagrams showing the display contents of the main screen. FIG. 5 shows the screen state when the whole blood mode is selected and FIG. 6 shows the screen state when the dilution mode is selected. In the figure, 511 is a measurement mode area, 512 is a whole blood mode selection area in which a push button is displayed, and 514 is a dilution mode selection area in which a push button is similarly displayed. Reference numeral 516 is a start button area in which a start button is displayed, 518 is a P / F area for paper feeding of the printer, 520 is a menu area for selecting various menus such as maintenance, setting and calibration, and 522 is an apparatus. QC area for quality control of 5
Reference numeral 24 is a measurement result area for calling the measurement result display screen for the already-measured sample, 526 is a shutdown area for starting the shutdown operation (stopping the apparatus after cleaning), and 528 is the necessary dispensing in the dilution mode. Is a dispensing area for.

A touch panel is attached to each of these areas at a corresponding position, and each function is input by touching (pressing) with a finger or the like, and each function is stored in the control unit 500 in advance. It is processed by being executed by. Reference numeral 510 is an area for inputting a sample number, and a numerical value or the like is input from a keyboard (not shown) (which may be displayed as a pop-up menu).

The selection of the measurement mode will be described. Figure 5
As shown in, whole blood mode area 512 and dilution mode area 5
14 shows a red "whole blood button" and a yellow "dilution button", respectively. The "whole blood button" and the "dilution button" have different button colors, and mistakes are reduced by utilizing the discrimination function by color.

Then, for example, when the "whole blood button" is touched, it is displayed as if it was pressed and pressed, while the "dilution button" is displayed as if it were popped out without being pressed. Conversely, if you touch the "dilution button", this will be pushed in,
The "whole blood button" appears to pop out. As a result, even a button on the touch panel, which is a two-dimensional plane, is visually stereoscopically displayed, and it becomes clear which is selected, so that an error in the measurement mode is less likely to occur.

[Whole Blood] and [Pre-Dil] are displayed below the “Whole blood button” and the “Dilution button”.
A display indicating the meaning of whole blood or dilution, such as “uted”, is displayed at the same time to prevent further mistakes.

Further, the color of the start button in the start area 516 is changed in association with the color of the selected measurement mode button. For example, in this embodiment, the "whole blood button" is displayed in red and the "dilution button" is displayed in yellow, but when the "whole blood button" is pressed and the whole blood mode is selected, the start button also turns red. ,
When the "dilution button" is pressed and the dilution mode is selected, the start button also changes to yellow. The "whole blood button" may always be displayed in red, or may be displayed in red only when the whole blood mode is selected. Similarly, the "dilution button" may be always displayed in yellow, or may be displayed in yellow only when the dilution mode is selected. In any case, the "whole blood button" and "dilution button" need not be displayed in the same color at the same time. It should be noted that it is preferable to select a color that is easy to distinguish in terms of color as the color of each button.

On the main screen, the measurement is started by touching the start button. However, if the cleaning operation is not completed, the reagent is insufficient, or the measurement operation is started when the device is in a trouble state, it may cause a further failure. Therefore, the control section 500 monitors the signals from the drive circuit section 501 and the like to grasp the reagent shortage and the apparatus state, and if the measurement preparation is completed, the start button area 5
16 to display the "start button", and when the preparation is not completed and the measurement is impossible or the trouble occurs, the "start button" itself is not displayed in the start button area 516 as shown in FIG. By
It eliminates the need to press the start button carelessly and makes it clear that the driver cannot start.

The objects monitored by the control unit 500 include, for example, the end information of the cleaning process, the panel open / close sensor J shown in FIG.
1. Device trouble information based on outputs of various sensors such as the sample detection sensor J2 are included. In addition, when the start button is not displayed, a displayable space is formed therein, so that the display may be performed with a large character indicating that the measurement is not possible.

Measurement Screen Next, the screen displayed during measurement will be described. Figure 8
Is a measurement screen immediately after the measurement is started by pressing the start button, FIG. 9 is a measurement screen after the measurement result of the WBC measurement sample is obtained, and FIG. 10 is a measurement screen after the measurement result of the RBC measurement sample is obtained. The measurement screen immediately after completion is shown.
8 and 9 which are screens during the measurement, a graphic display (triangle display) 53 showing the progress of the measurement by the change of the color.
0 is displayed at the bottom.

This measurement screen has five basic items (W
(BC, RBC, PLT, HGB, HCT) is displayed in a larger character size. Immediately after the start of measurement, no measurement result is obtained, so the measurement item (and its unit) is simply displayed. About 20 seconds after starting measurement, WB
Since the measurement by the C measurement sample is completed, the WBC and HGB data obtained by this measurement are immediately displayed as shown in FIG. After about 80 seconds, RBC
Since the measurement with the measurement sample is completed, the results of 5 items are displayed as shown in FIG.

Here, a “→” button (referred to as a “forward button”) which is a touch button provided at the lower right of FIG.
By touching 32, a measurement result display screen of 8 items as shown in FIG. 11 including each item of MCV (average red blood cell volume), MCH (average red blood cell hemoglobin amount), MCHC (average red blood cell hemoglobin concentration) is displayed. It Although all the items measured by this blood analyzer are displayed on this screen, the character size is small because there are many items.

Incidentally, the button 5 which advances further in FIG.
By touching 32, various statistical data screens regarding the measurement results of the WBC measurement sample and the RBC measurement sample as shown in FIGS. 12 and 13 may be displayed. Further, it may be set to be able to return from the state of displaying 8 items in FIG. 11 (or FIG. 4 (e)) to the state of displaying 5 items in FIG. 10 (or FIG. 4 (d)).

After that, by touching the "return" button 534 displayed at the upper right of FIGS. 11, 12, and 13, the main screen is returned.

Depending on the measurer, it may be desired to move to the next measurement without considering the display of 8 items (further, the statistical data screen). Therefore, when the non-operation state continues for about 20 seconds after the screen is moved to the screen of FIG. 10 until the cleaning process is completed, that is, when the “advance button” 532 for viewing the 8 item display is not operated during that time. , It automatically returns to the main screen because it is not necessary to see the data in FIG.

In the above embodiment, the basic 5
Although it is set to display items, it is possible to pre-register only the desired items of measurable items in advance, and to display only the items that are arbitrarily selected in addition to the screen that displays 8 items. May be provided.

FIG. 14 shows a screen when only WBC and RBC are registered as the first measurement screen. The operation of registering only an arbitrary item is performed by touching the menu area 520 of FIGS. 5 and 6 to call a “setting” screen and executing a program for designating a measurement item from the “setting” screen. In this program, the character size is predetermined according to the number of display items (for example, 20 points for up to 2 items, 16 points for up to 5 items, etc.), and the character size is determined according to the number of items.

Although the above embodiment relates to a blood analyzer, it can also be applied to various clinical analyzers including urine analyzers, and analyzers in the industrial field such as quality inspection of toner and pigment. It can be applied.

[0059]

According to the present invention, since the color of the start button is changed and displayed in correspondence with the color of the selected mode selection button, the measurement is started in the wrong mode selection state. It is possible to prevent erroneous operation.

Further, since the start button is not displayed when a trouble or the like affecting the measurement result occurs in the analyzer, it is possible to prevent the measurement from being started. In addition, it is possible to prevent a blank push and reduce the load on the touch panel.

Further, since the screen is automatically returned to the main screen if the measurement screen remains unoperated for a predetermined period of time, the operation can be simplified.

Further, since not only the screen for displaying all measurable items but also the basic items are displayed so that the character size is displayed large, it is possible to prevent the reading error.

Further, not only the screen for displaying all measurable items but also the necessary items are arbitrarily selected and displayed in a large character size, so that the reading error is prevented and the display is easy to use. You can
