Description

  The present invention relates to a biological information measuring device and a control method thereof.

A biological information measuring device such as a biological information monitor or a telemeter continuously measures so-called vital signs, such as an electrocardiogram, a respiratory rate, a heart rate, a blood pressure, a body temperature, and an arterial oxygen saturation (SpO ₂ ). It is a device that transmits and displays in real time. There are two types of biological information measuring devices: stationary type and portable type. Depending on the application, either type is used, but the portable type can be used as a stationary type or input a stationary type. Some have a configuration that can be used as a module (Patent Document 1).

JP 2014-132931 A

  The biological information measurement device has a function to measure various biological information, display the measured biological information in various forms, and notify the abnormality of the measured biological information, and can set and give instructions to the user. There are a wide variety of items you can do. Conventional biometric information measurement devices secure menus for selecting items to be set and displayed, and screen display areas corresponding to the items selected in the menus by reducing the display area of the biometric information being measured. Was. Therefore, while the menu or the screen corresponding to the item selected in the menu is being displayed, the number of displayed biometric information items has been reduced or the area per display item has been reduced.

  FIG. 7 shows an example of a display screen of a portable biological information monitor as an example of a conventional biological information measuring device. FIG. 7A shows an example of a normal state, and FIG. 7B shows an example of a menu display. I have. The layout (first layout) of the display screen 800 in the normal state includes a bibliographic information area 810 that displays bibliographic information such as patient information such as name, ID, and gender, and a biometric signal waveform determined in advance. A user who displays a waveform area 820 to be displayed, a measurement value area 830 to display a measurement value of biological information, and a user key having a plurality of selectable areas having a button-like appearance for realizing the assigned function with one touch. And a key area 840. Thus, in the first layout used for normal display, the waveform region 820 and the measurement value region 830 used for real-time display of measured biological information, which are the most important functions of the biological information monitor, are displayed on the screen. Make up the majority.

  For example, when the operation on the menu button 841 included in the user key is detected in the state of FIG. 7A, the layout of the display screen 800 is changed to the layout at the time of menu display as shown in FIG. 2 layout). The second layout is the same as the first layout for the bibliographic information area 810 and the user key area 840, except that the waveform area 820 ′ and the measurement value area 830 ′ are smaller, and the menu area 850 is newly included. I have.

  The menu area 850 displays a list of selectable menu items 851 classified by type, and when any menu item is selected, a corresponding screen (setting screen, report screen, etc.) is displayed in the menu area 850. Is displayed. For example, when an operation for a menu item “sound” classified as a type “basic setting” is detected, a screen for setting the volume and tone of an alarm sound or the like as shown in FIG. It is displayed in area 850.

  In the second layout used at the time of displaying the menu and at the time of displaying the setting screen and the report screen, at least one of the number and the length of the displayed waveforms in the waveform area 820 ′ is smaller than the first layout. In the measurement value area 830 ', at least one of the number of display items and the display size is reduced. Therefore, in the second layout, the number of pieces of biometric information that can be grasped is smaller than in the first layout, and the visibility of the biometric information is reduced. Therefore, it is not desirable to use the second layout unnecessarily. This is even more so with a portable biological information measuring device having a small screen.

  The menu display can be skipped by setting a function for calling a specific screen in the user key. However, if a user key corresponding to each of all menu items is provided, the trouble of searching for a desired item from the user keys increases, and the usability of the user keys decreases. Also, if the user key area is increased in response to the increase of the user key, the display area of the biological information (the waveform area 320 and the measurement value area 330) decreases.

  The present invention has been made in view of such problems of the related art, and provides a biological information measuring device and a control method thereof, which can suppress the visibility of the biological information being displayed from being reduced by menu display. Aim.

  The above object has a touch display device, a measuring unit for measuring biological information of a patient, and a control unit for controlling display on the touch display device, and the control unit converts the measured biological information into a first Detecting that a first operation has been performed on the touch display device while displaying biological information in the first layout on the display screen of the touch display device in real time in the layout or the second layout. Then, a first menu screen corresponding to a predetermined part of a plurality of menu items is superimposed on one edge of the display screen while displaying the biological information in the first layout, and the first menu is displayed. When detecting that an operation of selecting a menu item including another menu item has been performed on the screen, the biological information is displayed in the first layout. Meanwhile, when a second menu screen including another menu item is displayed, and an operation of selecting a menu item not including another menu item is detected on the first menu screen or the second menu screen, A screen corresponding to a menu item that does not include other menu items while terminating the display of the displayed menu screen and displaying the biological information in the second layout of the first menu screen and the second menu screen Is displayed in the area where the biological information was displayed in the first layout.

  With such a configuration, according to the present invention, it is possible to provide a biological information measuring device capable of suppressing the visibility of biological information being displayed from being reduced by menu display, and a control method thereof.

  Hereinafter, the present invention will be described in detail based on exemplary embodiments with reference to the drawings. Hereinafter, an embodiment in which the present invention is applied to a portable biological information monitor as an example of a biological information measuring device will be described. Here, “portable” means that it can be driven by a battery and can be moved with a patient while measuring biological information. The present invention is also applicable to a stationary biological information measuring device.

  FIG. 1 is a block diagram showing a functional configuration example of a portable biological information monitor 100 according to an embodiment of the present invention and a docking station (base unit) 200 for using the portable biological information monitor 100 as a stationary monitor device. It is. FIG. 2 is a perspective view showing an external appearance example of a portable biological information monitor 100 (hereinafter, simply referred to as a biological information monitor) and a docking station 200 of the present embodiment.

The biological information monitor 100 has an input unit 110 to which various sensors and measurement modules can be connected, and constantly monitors a patient's condition by displaying biological signals sequentially obtained from the sensors and detecting abnormalities. It is a device for performing. Since the biological information monitor 100 is generally used for a patient who needs to monitor vital signs, such as a critically ill patient, a plurality of biological information such as an electrocardiogram, a respiratory rate, a heart rate, a blood pressure, a body temperature, and an arterial oxygen saturation (SpO ₂ ) are used. It has a function to measure information.

  The input unit 110 includes a connector and an interface for mechanically and electrically connecting various sensors and measurement modules. In the present embodiment, it is assumed that the following sensors and measurement modules are connected as examples. Depending on the measurement module connected to the input unit 110, bidirectional communication is possible.

  The electrocardiographic electrode 111 is composed of a plurality of electrodes attached to a predetermined site on the surface of the limb and / or chest of the patient, and detects a lead waveform corresponding to the site. The number and type of the electrocardiographic electrodes 111 differ depending on the number and type of the lead waveform to be measured. In addition, the impedance of the rib cage is measured by applying a high-frequency weak current between the electrocardiographic electrodes, and the respiratory rate can be calculated by an impedance method of detecting the movement of the rib cage from the change. A blood pressure transducer 112 is attached to the end of a catheter inserted into a patient's blood vessel and converts blood pressure to an electrical signal.

The pulse wave / SpO ₂ sensor 113 is a so-called pulse oximeter, which optically detects and inputs arterial oxygen saturation (SpO ₂ ) and fingertip plethysmogram. Taking advantage of the fact that hemoglobin absorbs light differently depending on whether it is linked to oxygen and that the absorbance also differs depending on the wavelength of light, arterial blood oxygen saturation is generally measured using two wavelengths of red light and infrared light. Is measured. Further, since the AC component of the transmitted light or the reflected light changes according to the blood volume, this AC component is detected as an optical fingertip plethysmogram (PTG: photoplethysmograph).

The body temperature sensor 114 is, for example, a thermistor temperature sensor attached to the patient, and indicates a resistance value according to the temperature. The cardiac output sensor 115 is a thermistor temperature sensor placed in the blood vessel of the patient, and measures the blood temperature. A thermodilution curve is obtained from the time change of the blood temperature, and the cardiac output (CO) can be obtained from an infusion fluid temperature and a formula applying the Stewart-Hamilton formula. Further, the vascular resistance (SVR) can be obtained from the cardiac output and the blood pressure value. The cardiac output may be obtained non-invasively by the impedance method. Respiratory gas sensor 116 measures the concentration of carbon dioxide (CO ₂ ) in exhaled air. It should be noted that the sensors and modules connected to the input unit 110 shown in FIG. 1 are merely examples, and other components may be included, or some of the illustrated components may not be provided.

  The non-invasive blood pressure monitor 117 includes a cuff, a pump, an exhaust valve, a pressure sensor, and the like. By acquiring the signal of the pressure sensor, the blood pressure can be non-invasively measured by the oscillometric method. Since non-invasive blood pressure cannot be measured continuously, measurement is performed at predetermined intervals. The operation of the non-invasive blood pressure monitor 117 (the operation of the pump and the exhaust valve) is controlled by the control unit 140 through the input unit 110.

  The pre-processing unit 120 performs predetermined pre-processing on the biological signal input to the input unit 110 according to the signal, such as A / D conversion processing and application of a power supply noise removal filter, and stores the pre-processing in the buffer memory 130. I do. The preprocessing unit 120 may be configured by hardware such as a DSP or an ASIC, or at least a part of the function may be realized by software by the control unit 140. The buffer memory 130 is used as a temporary storage of signals, a work area of the control unit 140 and a video memory.

  The control unit 140 has a programmable processor such as a central processing unit (CPU), a RAM, and a ROM, and controls the operation of the biological information monitor 100 by loading a program stored in the ROM into the RAM and executing the program by the CPU. To achieve the overall function. Note that at least a part of the ROM may be rewritable.

  The external interface (I / F) 150 is a communication interface with the docking station 200, and is connected to the external interface 220 of the docking station 200 directly by a connector provided on the housing of the apparatus or via a cable. Whether the docking station 200 is connected or not and whether power is supplied from the docking station 200 can be detected by the control unit 140.

  When the control unit 140 determines that the operation of the device, the waveform or the value of the biological signal, or the like satisfies the conditions defined in the predetermined condition (alarm setting), the alarm indicator 160 is activated by, for example, light or sound. And one or more output devices for outputting and notifying the information. Alarm indicator 160 may typically be a light emitting element or a speaker. Warnings are classified into levels according to importance (level), and warnings according to the importance can be output. The alarm can be combined with not only the alarm indicator 160 but also a message display on the touch display 170 or the like. For example, when a predetermined operation on the operation unit 180 is detected, the control unit 140 stops outputting the alarm.

  The touch display 170 is a display device having a touch panel function. The control unit 140 causes the touch display 170 to display important biological information such as an electrocardiogram waveform, a heart rate, a body temperature, a blood pressure value, a respiratory rate, and a respiratory waveform in real time according to a predetermined layout. Further, control unit 140 changes the content and / or layout displayed on touch display 170 in response to an instruction from operation unit 180.

  The operation unit 180 is a group of keys and switches including a power switch, and enables a user to input instructions and information to the biological information monitor 100. Note that at least some of the switches and keys may be realized as software switches in which a touch panel provided on the touch display 170 and a GUI display by the control unit 140 are combined. The operation unit 180 may include external keys and switches.

  The wireless communication unit 190 transmits the measured data and information about an event that has occurred during the measurement to the external device, for example, the central monitor device or another biological information measuring device that takes over the measurement of the biological information. Used for There is no particular limitation on the protocol used for wireless communication, and for example, a near field communication (NFC) protocol such as Wi-Fi (IEEE 802.11x), Bluetooth (registered trademark), IrDA, and ISO / IEC 18092 can be used. Further, NFC may be used for the authentication process, and a plurality of communication methods may be combined, such as Bluetooth / Wi-Fi handover in which communication after the authentication process is performed using Bluetooth or Wi-Fi. Note that, instead of the wireless communication unit 190 (or in addition to the wireless communication unit 190), a wired communication unit for realizing the same function may be provided.

  In addition, in addition to the configuration shown in the figure, a configuration for handling a memory card (such as a memory card slot), a printer (recorder), or the like may be provided. Although the biological information monitor 100 can be driven by a battery, it can receive power from the docking station 200 through the external I / F 150 when connected to the docking station 200. When power is supplied through the external I / F 150, the biological information monitor 100 operates with the power from the external I / F 150 and charges the built-in battery.

  In the biological information monitor 100 having such a configuration, for example, when the power is turned on through the operation unit 180, the processing for the biological signal input through the input unit 110 is started. Specifically, the preprocessing unit 120 performs A / D conversion and the like, and starts storing various biological signals in the buffer memory 130 as measurement data. Then, the control unit 140 starts various parameter calculation processing, display processing, evaluation processing, abnormality determination processing, and the like for the measurement data stored in the buffer memory 130. Further, the control unit 140 transfers measurement data from the buffer memory 130 to the storage unit 195, and when a predetermined event occurs, associates predetermined information such as measurement data at that time with the event with the event in the storage unit 195. Or save. The control unit 140 further analyzes the measured biological signal, generates a report in a predetermined format, and displays the report according to a request. There are various types of reports, and a trend display that is useful for grasping a change over time of a biological signal or occurrence of an event is a typical example of the report.

  The docking station 200 reads data stored in the storage unit 195 of the biological information monitor 100, and transmits the data to an external device such as a central monitor or a server device for managing data relating to the biological information monitor 100 or a patient. Provides functions. The docking station 200 outputs measurement data to an external device in real time if the biological information monitor 100 is connected in a measurement state.

  The external I / F 220 is a communication interface for connecting the biological information monitor 100. The external I / F 200 is also used to supply power to the connected biological information monitor 100. Therefore, the docking station 200 is also an external power supply of the biological information monitor 100. The buffer memory 240 is used for temporarily storing the measurement data received through the external I / F 220, and is used as a work area of the control unit 210. The control unit 210 has a programmable processor such as a central processing unit (CPU), a RAM, and a ROM, and controls the operation of the docking station 200 by loading a program stored in the ROM into the RAM and executing the program by the CPU. To achieve the overall function. Note that at least a part of the ROM may be rewritable.

The operation unit 230 is a group of keys and switches including a power switch. When the biological information monitor 100 is connected, a part of the functions of the operation unit 180 of the biological information monitor 100 can be disabled, and the operation of the operation unit 230 can be enabled.
The communication unit 250 is connected to a network in the hospital and is used to communicate with an external device on the network. The communication unit 250 may be a wired communication unit or a wireless communication unit.
Bus 260 interconnects the components of docking station 200.

FIG. 2A is a perspective view showing an example of the appearance of the biological information monitor 100, and the same components as those in FIG. 1 are denoted by the same reference numerals.
As shown in FIG. 2C, the docking station 200 is provided with a space for mounting the biological information monitor 100. The biological information monitor 100 can be attached to the docking station 200 by directly fitting the connector of the external I / F 150 provided at the lower part on the right side surface to the connector of the external I / F 220 of the docking station 200. In addition, not only the connector of the external I / F 220 but also the housings of the biological information monitor 100 and the docking station 200 are fitted so that the biological information monitor 100 is not accidentally detached. FIG. 2B shows a state where the biological information monitor 100 is connected to the docking station 200.

  Next, a display control operation in the biological information monitor 100 according to the present embodiment will be described with reference to FIGS.

  FIG. 5A is a flowchart illustrating an outline of the operation of the biological information monitor 100 at the time of measurement. The biological information monitor 100 constantly measures the biological signal of the patient, and displays predetermined information based on the measured value in real time (S10).

  FIG. 3A shows an example of the layout (first layout) of the display screen 300 of the touch display 170 in the normal state of the biological information monitor 100 of the present embodiment. The first layout includes a bibliographic information area 310 for displaying bibliographic information such as patient information such as ID and gender, and date and time information, a waveform area 320 for displaying a waveform of a predetermined biological signal, and a measured value of biological information. And a measurement value area 330 for displaying Unlike the related art, there is no fixed display area for the user key.

  The control unit 140 monitors the operation on the touch display 170 while performing the measurement operation and the normal display in S10. Then, it is determined whether a predetermined n-th operation has been detected (S20). Here, n is a natural number, and is one of 1 to 4 in the present embodiment. Also, what kind of operation the n-th operation is, and what kind of operation to execute when the n-th operation is detected are set in advance and stored in the storage unit 195. .

  Therefore, in S20, the control unit 140 determines whether any of the predetermined first to fourth operations has been detected, and if none has been detected, returns the process to S10 to perform the measurement process and the normal process. Display processing is continued. On the other hand, if it is determined that any one of the predetermined first to fourth operations has been detected, control unit 140 advances the process to S30, executes the process for the detected operation, and ends the process in S10. Return to

  Here, the first to fourth operations corresponding to the display instruction on the first menu screen 340 may be any operations that can be detected as touch operations, but are not operations of tapping a predetermined GUI, but gestures. , The operation of moving the contact position in a predetermined pattern. This makes it unnecessary to provide a GUI display area. In the present embodiment, as an example, the first to fourth operations include, for example, an operation of moving the contact position continuously in the first to fourth directions different from each other and by a predetermined distance or more (in the first to fourth directions). Swipe operation). In the present embodiment, as an example, the first to fourth directions are rightward, upward, downward, and leftward, respectively, toward the screen. Note that an input of another gesture (trajectory of a specific pattern), an operation in which a relationship between a plurality of contact positions satisfies a predetermined condition, and the like may be detected as the first to fourth operations. Hereinafter, processing when each of the first to fourth operations is detected will be specifically described.

  If the control unit 140 detects that the first operation (swipe operation to the right) has been performed on the touch display 170 in S20, the control unit 140 displays the first operation shown in FIG. 5B. Execute the process. In the present embodiment, it is assumed that the first operation is associated with the display of the menu screen.

  In S110, control unit 140 causes the first menu screen to be displayed on one edge of the display screen of touch display 170. FIG. 3B shows an example in which the first menu screen 340 is superimposed on the left edge of the display screen. At this time, the first menu screen may be scroll-displayed so as to appear in the first direction from the end of the display screen.

  The first menu screen 340 is a part of menu items that can be selected on the biological information monitor 100. Specifically, it is a menu item that is selected in advance and that is frequently used, or a menu item that is not included in other menu items. In the present embodiment, a menu item included in the first menu screen is called a top-level menu item, and other menu items included in the menu item A are called lower-level menu items of the menu item A. . Further, a menu item including the menu item B is referred to as a menu item in an upper layer of the menu item B. As described above, in the present embodiment, the menu items have a hierarchical structure or a tree structure, and the control unit 140 first controls only the first menu screen 340 corresponding to the highest layer (including only the menu items of the highest layer). Is displayed.

  Among the menu items, a menu item including a menu item of a lower layer is provided with an index (here, for example, a right-pointing triangle) indicating the menu item. Further, control unit 140 causes close button 350 to be displayed adjacent to menu screen 340.

  In the present embodiment, when the menu screen is displayed, the layout is not changed even if the normal layout (first layout) is used. Then, by narrowing down the number of menu items to be included in one menu screen, the size of one menu screen is made sufficiently smaller than the waveform area 320. Therefore, even if the first operation is detected and the first menu screen 340 is displayed, the range of the waveform area 320 hidden by the first menu screen 340 replaces most of the waveform area and the measurement value area. It is much smaller than the conventional configuration (FIG. 7B) that displays the menu screen from the beginning. Therefore, even during the display of the first menu screen 340, all of the measurement value area 330 and most of the waveform area 320 are visible, and the decrease in visibility from the normal state where the first menu screen 340 is not displayed is small. It is greatly suppressed. Furthermore, since the first layout is maintained even when the first menu screen 340 is displayed, the size and display content of the measurement value area 330 are unchanged, and the visibility of the measurement value area 330 is changed to the first menu. It does not decrease due to the display of the screen 340.

  In S112, control unit 140 determines whether or not an operation (for example, a tap operation) for selecting any of the menu items included in first menu screen 340 has been detected. If not, the process proceeds to S124.

  In S114, the control unit determines that the selected menu item is a menu item that includes a lower layer menu item among the menu items included in the first menu screen 340 (in the example of FIG. 3B, “patient entry / exit”). Other than "). If it is determined that the menu item including the menu item of the lower layer is selected, the process proceeds to S116, and if not, the process proceeds to S118.

  In S116, control unit 140 displays a menu screen including lower-layer menu items (hereinafter, referred to as a lower-layer menu screen). In the present embodiment, the menu screen of the lower layer is displayed at a position adjacent to the menu screen including the selected menu item. Further, the control unit 140 changes the display position of the close button 350 to a position adjacent to the menu screen of the lower layer. For example, it is assumed that an operation of selecting the menu item “setup” on the first menu screen 340 in the state of FIG. 3B is detected. In this case, as shown in FIG. 3C, the control unit 140 places the second menu screen 345 including the menu items in the lower layer of “setup” adjacent to the first menu screen 340 including “setup”. To display. The size of the second menu screen 345 is equal to the size of the first menu screen 340.

  Note that the lower layer menu screen need not be displayed adjacent to the upper layer menu screen. For example, the menu screen of the lower layer may be displayed so as to replace the menu screen of the upper layer. Alternatively, it may be displayed so as to partially overlap the menu screen of the upper layer. In this case, the area occupied by the entire menu screen can be reduced while maintaining the functions of grasping the hierarchical structure of the menu and moving directly between the layers.

  As can be seen from FIG. 3C, even when the second menu screen 345 is additionally displayed, the visibility of the waveform area 320 is still maintained. Further, the visibility of the measurement value area 330 is not different from the normal state. If a menu item including another menu item is selected on the second menu screen 345, a third menu screen is displayed in the same manner, and thereafter, lower-level menu screens are sequentially displayed according to the hierarchical structure of the menu. Is displayed. When the lower layer menu screen is displayed, control unit 140 returns the process to S112.

  In this way, by sequentially displaying the menu screen as necessary, the range in which the menu screen is superimposed on the area for displaying the biological information is made as small as possible, and the visibility of the display related to the biological information is reduced. Is suppressed. As a secondary effect, since the number of menu items displayed on each menu screen is smaller than that of a conventional menu screen in which menu items are comprehensively arranged, it is easy to search for a desired menu item from the menu screen. become.

  On the other hand, if a menu item that does not include a lower-layer menu item is selected, the control unit 140 ends the display of all menu screens in S118. Then, in S120, control unit 140 changes the layout of the display screen to the second layout. Specifically, control unit 140 assigns the area where waveform area 320 was located to menu area 360. Further, the control unit 140 reduces the number of items in the measurement value area 330 'and arranges the waveform area 320' in an empty area. In the second layout, at least one of the number of displayable waveforms and the section length is smaller than in the first layout, and at least one of the display item and the display size of the measured value is also reduced. As an example of the second layout, FIG. 8B illustrates an example of a setting screen displayed when a selection operation of the menu item “sound” is detected from the second menu screen 345.

  In the present embodiment, the entire waveform area 320 in the first layout is allocated to the menu area 360, but a part may be allocated. Further, at least a part of the measurement value area 330 in the first layout may be assigned to the menu area. That is, in the second layout, a part of the area where the display related to the biological information is performed in the first layout is assigned to the menu area.

  Next, in S122, the control unit 140 displays a screen corresponding to the selected menu item (a setting screen, a screen (report) displaying measurement values in a specific format), and measurement values not displayed in the measurement value area 330. Screen, etc.) in the menu area 360. After that, a process corresponding to the screen displayed in the menu area 360 is executed, and the display process for the first operation ends.

  On the other hand, if it is not determined in S112 that an operation to select any of the menu items included in the first menu screen 340 has been detected, the control unit 140 determines in S124 whether the condition for ending the display of the menu screen has been satisfied. Is determined. The menu screen end conditions include that a predetermined operation (for example, a tap operation) on the close button 350 is detected, an operation that can be regarded as an operation reverse to the first operation is detected, and an operation on the menu screen is performed. The detection may not be performed for a certain period of time, but is not limited thereto. The operation that can be regarded as the reverse operation to the first operation may be, for example, a swipe operation in a direction opposite to the first direction.

  If it is determined that the condition for ending the display of the menu screen is satisfied, the control unit 140 ends all the display of the menu screen in S126, and ends the processing. When it is determined that the condition for ending the display of the menu screen is not satisfied, the control unit 140 returns the processing to S112.

  As described above, in the present embodiment, the menu items have a hierarchical structure or a tree structure, and first, only the menu screen corresponding to the uppermost layer of the menu structure is displayed. Then, in accordance with the selected menu item, a menu screen corresponding to the lower layer or a screen (setting screen or the like) corresponding to the selected menu item is displayed. As described above, by narrowing down menu items to be included in one menu screen, each menu screen can be reduced. Further, since a menu screen including only necessary menu items can be displayed, the display area of the menu screen can be minimized. Therefore, the visibility of the display area of the biological information during measurement, such as the waveform area 320, can be suppressed from being reduced by the display of the menu screen.

  Therefore, unlike the related art that displays a menu screen that comprehensively displays menu items, there is no need to secure the display area of the menu screen by changing the screen layout. For this reason, the display of the menu screen does not lead to a reduction in the number of items or the display size of the biometric information that can be immediately displayed.

  Further, as shown in FIGS. 3B and 3C, by making the menu screen translucent, it becomes possible to visually recognize the display content of the area where the menu screen is superimposed over the menu screen, and the visibility is improved. Can be further suppressed.

  On the other hand, when the control unit 140 detects that a predetermined second operation (upward swipe operation) has been performed on the touch display 170 in S20, the control unit 140 illustrated in FIG. A display process for the second operation is executed. In the present embodiment, it is assumed that the second operation is associated with the display of the user key.

  First, in S210, the control unit 140 changes the layout of the display screen. In the present embodiment, when the second operation is detected, the user key is displayed. When the user key 410 is displayed at a position overlapping the waveform area 320, the control unit 140 determines the size of the waveform area 320 in S210. May be changed. For example, a region where the user key 410 is superimposed can be excluded from the waveform region 320. This is because, unlike the menu screen 340, the user key 410 may be displayed for a long time.

  Next, in S212, the control unit 140 superimposes and displays the user key 410 on one edge (here, the left edge) of the display screen as shown in FIG. The user key 410 is a group of so-called shortcut keys, and a function to be executed when selected is assigned to each of a plurality of selectable areas having a button-like appearance. The function assigned to each area can be specified by the user.

  In particular, in a biological information measuring device having a small display screen such as a portable biological information monitor, it may be better to enlarge the waveform region 320 or the measured value region 330 rather than to display the user key 410 in a fixed manner. Therefore, the user key 410 is displayed only when an instruction (second operation) is given.

In S214, control unit 140 determines whether or not an operation of selecting any of user keys 410 has been detected. If it is determined that the operation has been detected, the process proceeds to S216, and if not, the process proceeds to S224.
In S216, control unit 140 executes the function assigned to the selected user key, and ends the process.

  If it is not determined in S214 that an operation to select any of the user keys has been detected, the control unit 140 determines in S224 whether or not the condition for terminating the display of the menu screen is satisfied. As the end condition of the menu screen, an operation of a predetermined hardware key or a hardware button included in the operation unit 180 is detected, an operation that can be regarded as an operation reverse to the second operation is detected, The operation on the user key 410 may not be detected for a certain period of time, but is not limited thereto. The operation that can be regarded as the reverse operation to the second operation may be, for example, a swipe operation in a direction opposite to the second direction.

  If it is determined that the condition for terminating the display of the user key 410 is satisfied, the control unit 140 terminates the display of the user key 410 in S226, and terminates the processing. When it is determined that the display termination condition of the user key 410 is not satisfied, the control unit 140 returns the process to S112.

  On the other hand, when the control unit 140 detects that a predetermined third operation (swipe operation in the downward direction) has been performed on the touch display 170 in S20, the control unit 140 illustrated in FIG. A display process for the third operation is executed.

  In step S310, the control unit 140 determines whether or not a screen that requires a change in the layout of the display screen is associated with the third operation, and changes the layout of the display screen if necessary. In the present embodiment, it is assumed that a setting screen of a time interval for executing the non-invasive blood pressure measurement (NIBP) is associated with the third operation. In the present embodiment, it is assumed that the display of the setting screen of the time interval for executing the NIBP is a screen that does not require a layout change (superimposed display). Therefore, control unit 140 does not change the layout in S310.

  In S312, control unit 140 displays a screen associated with the third operation. The display may be a translucent or opaque superimposed display or a display that replaces the normal waveform region 320 as described later, but is not limited thereto. As shown in FIG. 4B, the control unit 140 causes the NIBP execution timing setting screen 420 to be displayed in a translucent and superimposed manner.

  In step S314, the control unit 140 determines whether any selection operation has been detected on the screen displayed in step S312. If it is determined that the selection operation has been detected, the process proceeds to step S316. If not, the process proceeds to step S324.

  In S316, control unit 140 executes a function corresponding to the area in which the selection operation has been detected, and advances the process to S326. For example, in the example of FIG. 4B, it is set to execute the non-invasive blood pressure measurement at a time interval corresponding to the selected area.

  If it is not determined in S314 that the selection operation has been detected, in S324, the control unit 140 determines whether or not the condition for terminating the screen display is satisfied. The screen end conditions include a detection of an operation of a predetermined hardware key or a hardware button included in the operation unit 180, a detection of an operation that can be regarded as an operation reverse to the third operation, a display The operation on the screen may not be detected for a certain period of time, but is not limited thereto. The operation that can be regarded as the reverse operation to the third operation may be, for example, a swipe operation in the direction opposite to the third direction. When it is determined that the condition for terminating the display of the screen associated with the third operation is satisfied, the control unit 140 advances the processing to S326. On the other hand, when it is determined that the condition for terminating the display of the screen associated with the third operation is not satisfied, the control unit 140 returns the processing to S112.

  In S326, control unit 140 ends the display of the screen associated with the third operation, and ends the process. At this time, if the layout has been changed in S310, the control unit 140 restores the original layout.

  When the control unit 140 detects that a predetermined fourth operation (swipe operation to the left) has been performed on the touch display 170 in S20, the control unit 140 executes a display process for the fourth operation. I do. The display processing for the fourth operation may be the same as the display processing for the third operation, and a description thereof will not be repeated. In the present embodiment, it is assumed that the fourth operation is associated with the display of the trend screen.

  FIG. 4C shows a display example of the trend screen 430 displayed by the fourth operation in the present embodiment. The trend screen 430 is an opaque screen that requires a change in the layout of the display screen. Therefore, in S310, control unit 140 changes the screen layout to the second layout. The second layout at the time of displaying the trend shown in FIG. 4C and the second layout at the time of displaying the setting screen shown in FIG. 8B include a waveform area 320 ′ and a measurement value area 330 ′. Is different. As described above, the configurations of the waveform area 320 'and the measurement value area 330' in the second layout can be changed by setting.

  A screen (display operation) may not be associated with at least the second to fourth operations. The operation associated with the operation may be configured to be changeable by the user. When associating any display operation, information such as the layout of a screen used for display, whether to display in a superimposed manner, or to display in a translucent manner, can be registered in advance in association with display contents. Therefore, when the layout associated with the screen whose display is instructed is different from the current layout, control unit 140 changes the layout and displays the screen. Note that, in the present embodiment, a configuration using mainly two types of screen layouts has been described for ease of explanation and understanding. However, more screen layouts may be used.

  As described above, according to the present embodiment, only a menu screen including only some menu items among the selectable menu items is displayed first. After that, a menu screen including further menu items or a screen (setting screen or the like) corresponding to the selected menu item is displayed only when necessary according to the selected menu item. This makes it possible to suppress a decrease in the visibility of the biological information when the menu is displayed in the biological information measuring device that displays the patient's biological information in real time while measuring the biological information.

  Further, since the display of the menu screen can be instructed by a touch operation (here, a swipe operation) that does not require a GUI, an area for displaying the GUI for displaying the menu screen is not required. Therefore, it is particularly advantageous in a biological information measuring device with a small screen, such as a portable biological information monitor. Furthermore, if different touch operations are used to call operations other than the display of the menu screen, usability can be further improved.
