Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a biological information display device, and more particularly, to a biological information display device suitable for simultaneously displaying a plurality of biological information.
[0002]
[Prior art]
A biological information display device represented by a biological information monitor has a function of displaying various biological information including an electrocardiographic waveform, a blood pressure waveform, a respiratory waveform, and a pulse waveform. Among these biological information, when displaying information that changes periodically, for example, an electrocardiographic waveform, one that displays a mark (synchronous mark) at a timing corresponding to a characteristic point of the waveform (for example, an R wave in an electrocardiographic waveform). Are known.
[0003]
By performing the synchronization mark display, the observer can grasp the general trend of the state of the biological information (for example, pulsation in the case of an electrocardiographic waveform) without continuously watching the waveform display. Very useful.
[0004]
The display of the synchronization mark is also useful for a bedside monitor arranged for each patient, but is a very useful function particularly for a central monitor that monitors biological information of many patients at once.
[0005]
[Problems to be solved by the invention]
Such a synchronization mark display is normally displayed corresponding to any one of the waveforms even in an apparatus having a function of displaying a plurality of biological information waveforms. However, in a conventional biological information device, when a plurality of waveforms of biological information and a synchronization mark are displayed, it is not possible to clearly and easily grasp which waveform the synchronization mark corresponds to.
[0006]
That is, in general, the synchronization mark detects a predetermined portion (R wave or the like) of the electrocardiogram waveform and is often displayed at that timing. Therefore, the display position of the synchronization mark is within the area where the information regarding the electrocardiogram waveform is displayed. There are many. However, even when the ECG waveform cannot be acquired, such as when the ECG electrode cannot be worn due to the patient having a burn on the chest, etc. Some devices have a function of displaying a synchronization mark in synchronization with information (eg, a pulse wave detected at a fingertip or the like or an arterial pressure measured invasively). In such a device, just because the synchronization mark is displayed does not necessarily correspond to the electrocardiographic waveform, but conventionally, it is clear and clear which waveform the synchronization mark corresponds to. I could not easily know. Therefore, it is sometimes necessary to determine the correspondence by comparing the waveform display with the synchronization mark display.
[0007]
It is also known to output a synchronization sound together with a synchronization mark display. For example, a device for monitoring the biological information waveform of a plurality of patients, such as a central monitor, is configured to output a synchronization sound for a selected patient, but the same synchronization mark is displayed for all patients. In fact, it is very difficult to know which waveform of the patient is synchronized with the currently output synchronization sound.
[0008]
The present invention has been made in view of such problems of the related art, and is a biological information display device that displays at least one biological information acquired from a subject and performs synchronous display in synchronization with the biological information. It is another object of the present invention to provide a biological information display device capable of easily and clearly grasping the correspondence between the synchronous display and the biological information based on which the synchronous display is performed.
[0009]
[Means for Solving the Problems]
In order to solve the above-described problem, a biological information display device according to the present invention is a biological information display device capable of simultaneously displaying a plurality of preset biological information, among a plurality of input biological information, and displaying the same. Information display means for displaying a plurality of biological information, and synchronous display means for displaying a synchronization mark indicating a predetermined state of the predetermined biological information based on a predetermined one of the plurality of biological information displayed by the information display means The information display means performs a predetermined color-coded display corresponding to the type of the biological information, and the synchronous display means changes the display color of the synchronization mark to a predetermined biological The display color is equal to the display color of the information.
[0010]
Another biological information display device according to the present invention is a biological information display device capable of simultaneously displaying biological information on a plurality of patients, and an information display means for displaying biological information set in advance for each of a plurality of patients. And a synchronous display means for displaying a synchronization mark indicating a predetermined state of the biological information based on the biological information displayed by the waveform display means for each of a plurality of patients, wherein the synchronous display means is provided by a user. The display brightness of the synchronization mark for other patients is made lower than the display brightness of the synchronization mark corresponding to the selected patient, based on the input selection instruction for selecting one of the plurality of patients. .
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in detail based on preferred embodiments with reference to the accompanying drawings.
■ (Overall configuration of biological information system)
FIG. 1 is a diagram showing a configuration example of a biological information acquisition and display system as one embodiment of the biological information display device of the present invention.
As shown in FIG. 1, the biological information acquisition and display system according to the present embodiment has a configuration in which a bedside monitor device 100 and a central monitor device 200 are communicably connected by wireless (wired connection is possible). Generally, a plurality of bedside monitor devices 100 can be connected to one central monitor device 200, but FIG. 1 shows only one bedside monitor device 100 for simplicity of description.
[0012]
The bedside monitor device 100 is installed in a hospital room, an operating room, an intensive care unit, and the like, and is always placed near a patient. The multi-port module 2, the bedside monitor display unit 3, and the telemeter transmitter 4 are connected to the bedside monitor body 1 via cables. The multiport module 2 includes an electrocardiographic cable (also serving as a respiratory sensor) 5, a first blood pressure (aortic pressure) invasive blood pressure cable 6, a second blood pressure invasive blood pressure cable 7, a body temperature probe 8, a percutaneous oxygen saturation percentage. (SpO ₂ ), the pulse wave sensor 9, and the non-invasive blood pressure measurement cuff 10 are connected to each other, and the biological information collected from each sensor is output to the multiport module 2. The multiport module 2 performs processing such as amplification and digital conversion on biological information from each cable, probe, sensor, and the like, and transmits the information to the bedside monitor main body 1. In addition, the multiport module 2 in the present embodiment has two cables for measuring the invasive blood pressure, and is capable of measuring the invasive blood pressure of two channels. In addition, the blood pressure measured by the first invasive blood pressure cable 6 is set to the arterial pressure. There is no particular setting for the measurement site on the second blood pressure invasive blood pressure cable 7.
[0013]
The biological information is further displayed on the bedside monitor display unit 3 after being subjected to predetermined signal processing by a signal processing circuit (not shown) built in the bedside monitor main body 1. The signal processing circuit may be realized, for example, by executing software by a CPU, by using signal processing hardware such as a DSP or a dedicated circuit, or by a combination thereof.
[0014]
The bedside monitor body 1 controls the entire bedside monitor device 100 and realizes various functions of the device. The bedside monitor main body 1 is, for example, a computer having a CPU, a ROM, a RAM, an HDD, and various interfaces (a network interface, a video interface, an audio interface, a peripheral device interface, and the like). This can be realized by executing the program.
[0015]
The bedside monitor display unit 3 is connected to the bedside monitor main body 1 and displays biological information. A touch panel as a user interface is provided on the screen, and a speaker for outputting an alarm, a synchronization sound, a click sound for operation confirmation at the time of operating the touch panel, and the like are built in.
[0016]
The biological information is supplied to the telemeter transmitter 4 in addition to the bedside monitor display unit 3. When there are a plurality of types of biological information to be obtained, the number and types of biological information supplied to the bedside monitor display unit 3 and the biological information supplied to the telemeter transmitter 4 may be different. , May be the same. In the present embodiment, it is assumed that all of the acquired biological information (which may include information other than the information actually acquired by the multiport module 2, such as patient-specific information) is supplied to the telemeter transmitter 4. .
[0017]
The telemeter transmitter 4 transmits the biological information supplied from the bedside monitor main body 1 to the central monitor 200 located at a position apart from the bedside monitor 100 by wireless or wired. The central monitor main body 11 of the central monitor device 200 is realized by, for example, a general-purpose computer device like the bedside monitor main body 1. When information from the bedside monitor device 100 is received through the telemeter receiver 12, a predetermined signal is generated as necessary. After performing the processing, the biological information is displayed on the central monitor display unit 13.
[0018]
The central monitor display unit 13 is connected to the central monitor main body 11 and displays biological information on a plurality of patients. Therefore, by observing the central monitor display unit 13, the medical staff can manage the states of a plurality of patients at a location away from each patient and intensively. In addition, similarly to the bedside monitor display unit 3, a touch panel as a user interface is provided on the screen, and a speaker for outputting an alarm, a synchronization sound, a click sound for operation confirmation at the time of operating the touch panel, and the like are built in. I have.
[0019]
■ (Biological information display on the bedside monitor display)
Next, a display format of the bedside monitor display unit 3 in the present embodiment will be described with reference to FIG. The display is realized by the bedside monitor display unit 3 displaying the display data generated by the bedside monitor main body 1. The display area 21 of the bedside monitor display unit 3 is roughly divided into a numerical value display area 22 on the right and a waveform display area 23 on the left.
[0020]
The numerical value display area 22 is an area for numerically displaying biological information. In the present embodiment, a heart rate (HR), an arterial blood pressure value (ART), a second open blood pressure value (BP2), Percutaneous oxygen saturation percentage (SpO ₂ ), pulse wave pulse rate (PR), non-invasive blood pressure value (NIBP), and respiration rate (RR) display blocks 221 to 226 are formed. Each numerical value, other related information, and a synchronization mark described later are displayed. The number and type of numerical information displayed in the numerical display area 22 are not limited to these, and can be set as appropriate.
[0021]
The waveform display area 23 is an area for displaying a biological information waveform. In the present embodiment, an electrocardiogram waveform 231, an arterial pressure waveform 232, a second invasive blood pressure waveform 233, and a percutaneous oxygen saturation waveform (SpO ₂ Waveform 234 and the impedance respiratory waveform (RESP) 235 are displayed. The number of simultaneously displayable waveforms and the types of waveforms to be displayed can be arbitrarily set.
[0022]
In addition, the display area 21 displays the patient's name, gender, age, current date and time, and other information and operation buttons. However, these are not directly related to the present invention, and the description is omitted. I do.
[0023]
A touch panel is provided in the display area 21 of the bedside monitor display unit 3, and various settings for the bedside monitor main body 1 can be performed by pressing the display area with a finger. As a setting method, a method generally used in a GUI, such as selecting a desired item from a hierarchical menu screen, can be used. Selection of parameters to be synchronized described below can also be performed from a menu operation on the touch panel.
[0024]
The display color in each block of the numerical value display area 22 and the display color of the waveform in the waveform display area 23 are respectively associated with each other. For example, the electrocardiogram waveform 231 and the heart rate block 221 are green, and the first invasive blood pressure waveform 232 and The arterial blood pressure value block 222 is vermilion, the second invasive blood pressure waveform 233 and the second invasive blood pressure value block 223 are light blue, the percutaneous oxygen saturation waveform 234 and the percutaneous oxygen saturation percentage and pulse wave pulse rate block. Reference numeral 224 denotes yellow, other waveforms and numerical items, that is, the impedance respiratory waveform 235, the non-invasive blood pressure value block 225, the respiratory rate block 226, and the body temperature value are white in the example of FIG. These display colors can be changed by, for example, a menu operation using a touch panel.
[0025]
In the present embodiment, a synchronization mark can be displayed for each block corresponding to the biological information capable of generating a synchronization mark among the display blocks in the numerical value display area 22. Specifically, each of the heart rate block 221, the first invasive blood pressure value (arterial blood pressure value) block 222, the second invasive blood pressure value block 223, and the percutaneous oxygen saturation percentage and pulse wave pulse rate block 224. In addition, synchronization marks 24 to 27 can be displayed. FIG. 2 shows a state in which all the synchronization marks 24 to 27 are displayed for the sake of convenience, but in an actual operation, among the synchronization marks 24 to 27, the type of the waveform that is actually the source of the synchronization mark generation is Only the corresponding one is displayed.
[0026]
Since the respiration, body temperature, and non-invasive blood pressure are not suitable for synchronization with the above-described biological information, a synchronization mark corresponding to the biological information is not prepared in the present embodiment.
[0027]
In the present embodiment, the synchronization marks 24 to 27 are basically turned on (displayed) in synchronization with the phase at which the peak value of the corresponding waveform becomes maximum, and are turned off (not displayed) at other times. Become. Specifically, the electrocardiogram waveform synchronization mark 24 is turned on in synchronization with the R wave of the electrocardiogram waveform 231, and the arterial pressure waveform synchronization mark 25 is the maximum pressure of the arterial pressure waveform 232 and the second invasive blood pressure waveform synchronization mark 26. Is turned on at the highest pressure of the second invasive blood pressure waveform 233, and the pulse wave synchronization mark 27 is turned on in synchronization with the moment when the peak value of the percutaneous oxygen saturation (SpO ₂ ) becomes maximum. Incidentally, the pulse wave synchronization mark 27, but performs display based on the waveform of SpO _2, it is carried out for the sake of convenience on the display section of the pulse wave pulse rate. Note that the synchronization mark does not necessarily need to be displayed based on the local maximum point of the waveform, but may be displayed based on other characteristic points including the local minimum point.
[0028]
Which waveform (biological information value) to display the synchronization mark can be changed by setting using the touch panel. Further, by setting, a synchronization sound can be generated from a speaker (not shown) built in the bedside monitor display unit 3 in synchronization with the display of the synchronization mark.
[0029]
FIG. 3 is an enlarged view of the synchronization marks 24-27. As is clear from the figure, the ECG waveform synchronization mark 24, the arterial pressure waveform synchronization mark 25, the second invasive blood pressure waveform synchronization mark 26, and the pulse wave synchronization mark 27 are easy to intuitively grasp the type of the synchronization mark. It has a shape.
[0030]
As described above, in the present embodiment, in the biological information display on the bedside monitor device, the synchronization mark can be individually displayed for each corresponding biological information, and the display color is matched with the display color of the corresponding biological information waveform. Accordingly, it is possible to easily and clearly grasp which biological information the displayed synchronization mark corresponds to. Furthermore, by making the shape of the synchronization mark a shape suggesting the type of the corresponding biometric information, the correspondence with the biometric information is further clarified.
[0031]
■ (Biological information display on the central monitor display)
Next, a display format of the central monitor display unit 13 in the present embodiment will be described with reference to FIG. The display is realized by the central monitor display unit 13 displaying display data generated by the central monitor body 11 processing biological information received from the plurality of bedside monitor bodies 1. The central monitor body 11 may perform synchronous display on the central monitor display unit 13 using information necessary for synchronous display received from the bedside monitor device 100, or the bedside monitor device 100 The side may receive only the type information of the biological information used for the synchronous display, and the central monitor main body 11 may generate data for the synchronous display from the biological information.
[0032]
FIG. 4 shows a display example on the central monitor display unit 13. Here, information for four persons is displayed for simplicity of explanation, and the waveform display shows only the electrocardiogram waveform, but is connected to the bedside monitor device 100 of each patient as described above. Since the telemeter transmitter 4 transmits all the acquired biological information, it is possible to display a waveform other than the electrocardiogram waveform. Also, it is possible to display a plurality of waveforms for each patient.
[0033]
As shown in FIG. 4, a display area 41 of the central monitor display unit 13 is assigned a display area for one row for each patient, and each display area is a numerical display area 42 similar to the display on the bedside monitor display unit 3. And a waveform display area 43.
[0034]
Here, an electrocardiogram waveform is displayed in the waveform display area 43 for all patients, a heart rate (HR), an electrocardiogram waveform synchronization mark (44 to 47), and other numerical items such as an arterial blood pressure value are displayed in the numerical value display area 42. Shall be.
[0035]
The biological information displayed for each patient on the central monitor display unit 13 is arbitrary, and may not necessarily be the same for all patients (floor). Further, as shown in FIG. 4, the types of items displayed in the numerical value display area 42 can be set for each patient. However, in principle, it is preferable to determine the waveform type and the numerical display items so that a synchronization mark of the same type as the synchronization mark displayed on the bedside monitor device 100 is displayed.
[0036]
A touch panel is also provided in the display area 41 of the central monitor display unit 13, similarly to the bedside monitor display unit 3. By pressing this with a finger, a menu window is opened, and various settings can be made. Further, the patient can be selected by pressing the inside of the numerical value display area 42 corresponding to each patient. Further, the central monitor display unit 13 also has a built-in speaker for generating a synchronization sound in advance.
[0037]
FIG. 4 shows a state in which the numerical value display area 421 corresponding to the patient displayed third from the top is pressed and selected. As shown in the figure, in the present embodiment, in order to clarify the selected patient, the display of an arbitrary portion in the waveform display area 431 of the selected patient and the synchronization mark of the numerical value display area 421 are selected. Should be visually different from the indications for unpatiented patients.
[0038]
In the present embodiment, the label “BED-003” indicating the bed number in the waveform display area 431 is highlighted and the display brightness of the synchronization mark 46 in the numerical value display area 421 corresponds to the patient not selected. The brightness of the synchronization marks 44, 45, and 47 of the selected patients is reduced (in FIG. 4, the synchronization marks 46 of the selected patient are painted black and the synchronization marks 44, 45, and 47 of the other patients are white). Are shown here). At this time, it is preferable that the luminance is not changed for items other than the synchronization mark displayed in the numerical value display area corresponding to the non-selected patient. This is because the displayed numerical value is important for management, and it is not desirable to reduce the visibility of such important information.
[0039]
In addition, a method of changing the display color of the selected patient to another color different from that of another patient is also conceivable. However, as described above, the display color is associated with the waveform type, or the standard (for example, JIS T0601). -1) Because the colors that can be used as display colors are limited due to factors such as discrimination and the like, the method of clearing the visual difference without changing the color itself, such as reverse display or change in luminance, is better. Is considered preferable from the viewpoint of prevention of misidentification and distinctiveness.
[0040]
Therefore, when the display color of the electrocardiogram waveform and the heart rate display block is set to green, as described in the display of the bedside monitor display unit 3, the synchronization mark 46 of the third floor (BED-003) has the normal brightness. And the synchronization marks 44, 45 and 47 on the other floors (BED-001, 002, 004) are displayed as low-luminance green. Of course, a visual difference may be provided by increasing the brightness of the synchronization mark 46 of the selected patient, but from the viewpoint of visibility, the brightness of the synchronization marks 44, 45 and 47 of the non-selected patient is reduced. Is more preferred.
[0041]
When outputting the synchronization sound, the synchronization sound for the selected patient is generally output. However, the display is performed so that the selected patient is clearly displayed, and the synchronization sound is generated from the central monitor display unit 13. It becomes clear at a glance which patient's ECG waveform the synchronization sound is synchronized with.
[0042]
In the state of FIG. 4, when the numerical value display area 422 corresponding to “BED-004” is pressed with a finger, the fourth floor is selected, and the “BED-004” display in the waveform display area 432 is inverted, and the fourth floor is inverted. The floor synchronization mark 47 changes to a normal green display, while for the third floor, the “BED-003” display in the waveform display area 431 returns to the normal display, and the synchronization mark 46 changes to dark green. If the output of the synchronization sound is set, the synchronization sound to be output is changed from the synchronization sound for the ECG waveform on the third floor to the synchronization sound synchronized with the ECG waveform on the fourth floor.
[0043]
In this embodiment, the synchronization mark is displayed as blinking.However, in order to prevent the light-off state from continuing when the peak value is not clear or when the blinking interval is long, the size is not blinking but changes stepwise. May be displayed.
[0044]
Further, the shape of the synchronization mark displayed on the central monitor display unit 13 can also be changed by the corresponding biological information, similarly to the display on the bedside monitor display unit 3.
[0045]
In addition, the shape of the synchronization mark is not limited to the present embodiment, but may be variously changed, and the same shape may be associated with a plurality of types of biological information. Instead of separately providing a synchronization mark, a label display such as “HR” or “PR” can be used as the synchronization mark. That is, these labels may be displayed blinking in synchronization with the biological information. In this case, the central monitor display unit 13 may use other display elements unique to the patient, such as “BED-001” and the patient name.
[0046]
Note that the size and arrangement of the display area shown as a display example, the actually displayed numerical values, character strings, icons, and the like are not limited to the disclosed positions and sizes, and can be arbitrarily set. is there.
[0047]
In the above embodiment, the biological information acquisition and display system having both the bedside monitor device 100 and the central monitor device 200 has been described, but the biological information display device and the biological information display method of the present invention are only one of them. It goes without saying that it may be implemented by
[0048]
Furthermore, in the above-described embodiment, only the case where the synchronization mark is displayed in the numerical value display area has been described. May be configured to display the synchronization mark described above.
[0049]
Similarly, in the above-described embodiment, only the bedside monitor device and the central monitor device having both the region for displaying the waveform of the biological information and the region for numerically displaying the biological information have been described, but the biological information display device according to the present invention is described. Does not necessarily require both waveform display and numerical display. For example, in the case of a monitor device that does not perform waveform display, the color of the numerical value display of the biological information and the display color of the synchronization mark based on the biological information may be made equal. Conversely, when performing only the waveform display of the biological information, the display color of the synchronization mark based on the biological information may be the same color as the waveform display.
[0050]
Further, the monitor device connected to the central monitor device 200 is not limited to the bedside monitor device, but may be a telemeter device mounted on the subject. In this case, if the telemeter device does not have a signal processing function for displaying a synchronization mark, signal processing for displaying a synchronization mark may be performed in the central monitor main unit 11 from the received biological information.
[0051]
In addition, the configuration (multi-port module 2, various sensors, and the like) for acquiring biological information in the above-described embodiment is not necessarily a configuration necessary for the present invention, and a device that reproduces and displays previously recorded biological information. It is needless to say that the present invention can be applied also to the above.
[0052]
Also, only the case where a touch panel is used as the user input device has been described, but other input devices such as hardware buttons and keys, a trackball, and a mouse may be used.
[0053]
【The invention's effect】
As described above, according to the present invention, in displaying biological information, it is possible to easily and clearly grasp the correspondence between the synchronous display and the biological information on which the synchronous display is based.
