Description

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

For example, biological information such as heart rate, respiratory rate, blood pressure, arterial oxygen saturation (SpO ₂ ) is widely measured to diagnose the presence or absence of a patient's disease, identify the disease, and manage physical condition. ,It's being used. As an expression for performing the evaluation regarding the time change of the biological information, there is known a trend graph in which the measurement date and time is assigned to the horizontal axis and the measurement value range is assigned to the vertical axis and the measurement value is represented by a line graph (Patent Literature). 1).

JP 2010-82009 A (FIGS. 8 to 9)

  The trend graph works well when evaluating temporal changes related to measurement values of one type of biological information. However, as the number of types of biological information to be evaluated simultaneously increases, the scale of measurement values assigned to the vertical axis, the range of values, etc. There was a problem that it became complicated and the legibility deteriorated rapidly. The readability can be improved to some extent by changing the color and thickness of the line for each type of biometric information, or by shifting the biometric information with completely different measurement value ranges to a position where the polyline does not overlap. However, it has its limits. Further, for example, it is not possible to indicate a normal range that differs for each piece of biological information together with a measured value.

  The present invention has been made in view of such problems of the prior art. The present invention relates to a biological information output device capable of outputting biological information capable of providing other information useful for evaluation of measurement values while suppressing a decrease in visibility due to an increase in the types of biological information to be evaluated simultaneously. The purpose is to provide the control method.

Plots the measured data measured at different dates and times on the multiple axes extending radially from the origin, and uses the measured data measured at the same date as the apex among the plotted measured data This is achieved by a biometric information output device characterized by performing output by showing a figure.

  With such a configuration, according to the present invention, output of biological information that can provide other information useful for evaluation of measurement values while suppressing a decrease in visibility due to an increase in the types of biological information to be evaluated simultaneously is output. A possible biological information output device and control method thereof can be provided.

  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 biological information monitor as an example of a biological information output apparatus will be described. In addition, by carrying out the invention with a device that measures and presents biometric information in parallel (in real time), such as a biometric information monitor, it is easy to compare multiple types of biometric information and measure changes over time during measurement. This is useful in diagnosing the condition of the patient being measured. However, the function related to measurement is not essential to the present invention, and the present invention can be implemented in any electronic device that can read a measurement result of biological information from a network, a memory card, or the like and execute a presentation process described later. This electronic device includes a computer using device such as a personal computer, a tablet terminal, and a mobile phone.

FIG. 1 is a block diagram illustrating a functional configuration example of a biological information monitor (hereinafter simply referred to as a biological information monitor) 100 as a biological information output apparatus according to an embodiment of the present invention. The biological information monitor 100 includes an input unit 110 to which various sensors and measurement modules can be connected. The biological information monitor 100 constantly monitors a patient's state by displaying biological signals sequentially obtained from the sensors and detecting abnormalities. It is a device for doing. Since the biological information monitor 100 is usually used for patients who need to monitor vital signs such as critically ill patients, a plurality of living bodies such as an electrocardiogram, respiratory rate, heart rate, blood pressure, body temperature, arterial oxygen saturation (SpO ₂ ) and the like are used. It has a function to measure information.

The input unit 110 includes connectors and interfaces that mechanically and electrically connect various sensors and measurement modules. In the present embodiment, it is assumed that the following sensors and measurement modules are connected as an example.
The electrocardiogram electrode 111 is composed of a plurality of electrodes attached to a predetermined part of the patient's limbs and / or chest surface, and detects an induced waveform corresponding to the attachment part. The number and type of electrocardiographic electrodes 111 vary depending on the number and type of induced waveforms to be measured. Further, the respiration rate can be calculated by an impedance method in which a thin high-frequency current is passed between the electrocardiographic electrodes to measure the impedance of the thorax, and the movement of the thorax is detected from the change. A blood pressure transducer 112 is attached to the end of a catheter inserted into the patient's blood vessel and converts blood pressure into 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 volume pulse wave. Utilizing the fact that the light absorbance of hemoglobin varies depending on whether it is associated with oxygen, and also the absorbance varies depending on the wavelength of light. Generally, arterial oxygen saturation is obtained using two wavelengths of red light and infrared light. Measure. Further, since the AC component of the transmitted light or reflected light changes according to the blood volume, this AC component is detected as an optical fingertip volume pulse wave (PTG: photoplethysmograph).

The body temperature sensor 114 is, for example, a thermistor temperature sensor attached to a patient, and indicates a resistance value corresponding 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 equation applying the infusate temperature and the Stewart-Hamilton formula. Further, 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. The respiratory gas sensor 116 measures the carbon dioxide (CO ₂ ) concentration in the exhaled breath. Note that the sensors and modules connected to the input unit 110 illustrated in FIG. 1 are merely examples, and other components may be included, or some of the illustrated components may be omitted.

  The biometric information monitor is a device that continuously measures biometric information and performs real-time display and output to an external device such as a central monitor. ing. However, the present invention can be applied even to values measured intermittently. Therefore, for example, a blood pressure value can be measured noninvasively using a cuff.

  The preprocessing unit 120 performs preprocessing predetermined according to a signal, such as application of an A / D conversion process or a power supply noise removal filter, on the biological signal input to the input unit 110 and saves the same in the buffer memory 130. To do. The preprocessing unit 120 may be configured by hardware such as a DSP or an ASIC, or at least a part of functions 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 it by the CPU. To achieve the overall functionality. Note that at least a part of the ROM may be rewritable.

  The external interface (I / F) 150 is a communication interface with the host monitor 200, and is connected to the external interface 220 of the host monitor 200 directly or via a connector provided on a housing of the apparatus.

  The alarm indicator 160 is alerted by light or sound, for example, when the control unit 140 determines that the operation of the device, the waveform or numerical value of the biological signal, etc. satisfy the conditions defined in a predetermined condition (alarm setting). Are one or more output devices for outputting and notifying. The alarm indicator 160 may typically be a light emitting element or a speaker. Alarms can be classified according to importance (level), and alarms according to importance can be output. The warning can be combined with not only the alarm indicator 160 but also a message display on the display unit 170. For example, when a predetermined operation on the operation unit 180 is detected, the control unit 140 stops outputting the alarm.

  The display unit 170 is typically a color liquid crystal display, and the control unit 140 displays important biological information such as an electrocardiogram waveform, a heart rate, a body temperature, a blood pressure value, a respiration rate, and a respiration waveform according to a predetermined layout. It is displayed on the display unit 170 in real time. In addition, the control unit 140 changes the display content and layout of the display unit 170 in response to an instruction from the operation unit 180.

  An operation unit 180 that receives a user operation is a key and a switch group including a power switch, and allows the 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 a software switch that combines a touch panel provided on the display unit 170 and a GUI display by the control unit 140. The operation unit 180 may include an external key or switch.

  The printer 190 prints out a report related to the measurement result on a recording medium such as paper in a preset format. The printer 190 is not necessarily built in the biological information monitor 100 and may be one of external devices connected to the external I / F 150. The printer 190 is not essential.

The storage unit 195 is at least a part of a nonvolatile storage device, and is used to store setting information that is not in the ROM in the control unit 140, measured data, a value calculated based on the data, and the like. it can. It is assumed that the measurement data is associated with the measurement date / time. Here, the measurement date and time associated with the measurement data may not necessarily be the actual measurement date and time depending on the type of parameter. For example, systolic blood pressure, diastolic blood pressure, and average blood pressure cannot be measured strictly at the same time, but the values measured for the same heart rate are treated as if they were measured at the “same date and time”. Associate). The date and time to be associated at this time is determined in advance, for example, the date and time when all the measurement values for the same heart beat are obtained. Therefore, in this specification, “measurement date and time is the same” measurement data means measurement data having the same measurement date and time.
In addition to the illustrated configuration, a configuration for handling a memory card (such as a memory card slot) or a configuration for using a cuff (such as a pump or a pressure sensor) may be included.

  In the biological information monitor 100 having such a configuration, for example, when the power is turned on through the operation unit 180, processing for a 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. In addition, the control unit 140 transfers measurement data from the buffer memory 130 to the storage unit 195, or when a predetermined event occurs, the control unit 140 associates predetermined information such as measurement data at that time with the event in the storage unit 195. Save it.

(Report output processing)
Next, an example of report output processing and report format of the biological information monitor 100 of this embodiment will be described. In the present embodiment, the report output process is performed during measurement of biological information on the assumption that the measurement is performed on a biological information monitor. Can be executed at the timing. When executing report output processing using recorded data, the control unit displays a list of patients having measurement data in an accessible storage device in a selectable manner, and the measurement data for the patient selected through the operation unit. The report output process may be implemented for

  When a report output instruction is given through the operation unit 180 during measurement, the control unit 140 performs the report output process shown in the flowchart of FIG. 2 while continuing measurement processing and monitoring of measurement data based on alarm settings in the background. .

  First, the control unit 140 acquires, from the measurement data stored in the storage unit 195, measurement data at two points on the time axis and corresponding to the type of biological information corresponding to the report format ( S101). There are no particular restrictions on the two points on the time axis acquired here, but one is the most recent (current) measurement data. There is no particular limitation on how much previous measurement data is read out as the other (that is, past measurement data), but it can be 48 hours ago, for example. For example, when the effect of periodic medication is grasped, it may be set to acquire measurement data at the most recent specific time instead of the relative time based on the current time.

  In S101, if a predetermined event occurs during the measurement period of the measurement data to be read, the control unit 140 also reads information on the event type and the occurrence time from the storage unit 195.

  In S103, the control unit 140 changes the layout of the display unit 170 from a normal layout for real-time display to a layout for report display, and displays a report. In addition, although report display may be performed on a full screen, real-time display may be continued in the peripheral area | region of report display about predetermined biological information.

  In the present embodiment, the report output is performed by, for example, drawing a polygon with the coordinates corresponding to the measurement values as vertices on a specific template image corresponding to the report format, or drawing an index at a position corresponding to the date and time. It can be realized by the processing. Since these processes can be realized by a known method according to the basic software used by the biological information monitor 100, a detailed description thereof will be omitted.

FIG. 3 is a diagram illustrating an example of a report format output to the display unit 170 by the biological information monitor 100 according to the present embodiment.
The report has a graph area 310 for plotting measurement data, and a time axis area 320 for indicating measurement date and time and event information of the plotted measurement data.

The graph area 310 has a so-called radar chart format having an n-corner shape corresponding to the type n of biological information to be plotted. In the example of FIG. 3, the heart rate (HR), open blood pressure (IBP), respiratory rate (RR), arterial blood oxygen saturation (SpO ₂ ), carbon dioxide concentration (CO ₂ ), body temperature (TEMP) clockwise from the top. The measurement data (measurement values) of the six types of biological information are plotted on a plurality of axes extending radially from the center (origin) to the apex.

  The time axis area 320 represents a length of time including the measurement date and time of the measurement data plotted in the graph area 310. In the time axis area 320, indicators 322, 324, and 326 indicating positions on the time axis corresponding to the measurement date and time and the event occurrence date and time are displayed. In the example of FIG. 3, the latest measurement at the time when the report display instruction is given is performed at 10:00 on December 26, and is indicated by an index 322. Further, 10:00 of 12/24 retroactive for 48 hours is indicated by an index 324, and two events occurring at two measurement date times are indicated by an index 326, respectively.

  In the graph area 310, a polygonal outline (hereinafter referred to as a graphic) 314 connecting the coordinates on the plotted axes is measured at the date and time indicated by the index 322, and the graphic 312 is measured at the date and time indicated by the index 324. Correspond to each of the data. In order to make it possible to visually recognize the correspondence between the index and the graphic, the control unit 140 displays the corresponding date and time index and the graphic in the same color. Therefore, the index 322 and the graphic 314 are displayed in the first color, and the index 324 and the graphic 312 are displayed in the second color. Further, the control unit 140 displays the index 326 indicating the occurrence of the event in a color corresponding to the type of event. In the example of FIG. 3, since the same type of event has occurred twice, the two indicators 326 are displayed in the same color.

  In addition, the control unit 140 can display graphics 316 and 318 indicating normal value ranges for individual biological information in the graph area 310. Here, the graphic 318 indicates the lower limit value of the normal range, and the graphic 316 indicates the upper limit value of the normal range. The graphics 316 and 318 are displayed in the third color. Note that the graphics 316 and 318 indicating the normal range may not be displayed, or may be switched on / off according to an instruction through the operation unit 180. Moreover, you may show a figure only about one of an upper limit and a lower limit.

  The time axis region 320 can be operated. For example, the index 322 and the index 324 can be moved in the time axis direction. When the display unit 170 is a touch display or the operation unit 180 includes a pointing device such as a mouse, the user can change the position of the index on the time axis by dragging a desired index. Note that these are examples of operations for moving the index, and other operation methods may be employed. Further, the operation unit 180 may include buttons and keys for moving each of the indexes 322 and 324.

  Returning to FIG. 3, in step S107, the control unit 140 determines whether or not an instruction to change the measurement date and time of the data to be displayed (plotted) (an operation to move at least one of the indexes 322 and 324) has been issued. When the date / time change instruction is detected, the control unit 140 advances the process to S111 to execute the report output update process. That is, for the graph area 310, the control unit 140 plots the measurement data measured at the date and time corresponding to the position after the movement of the index, instead of the measurement data measured at the date and time corresponding to the position before the movement of the index. And about the time-axis area | region 320, the display position of a parameter | index is changed according to movement operation. When the report output is updated, the control unit 140 advances the process to S113. In addition, regarding the index whose position has been changed, the date and time after the change may be displayed in the time axis region 320.

  Thus, the user can easily compare the measurement data at two desired points on the time axis by changing the positions of the indexes 322 and 324. Further, if the report output update process is continuously executed while the index movement operation is performed, it is possible to easily grasp the temporal change of the measurement data from the shape change of the figure accompanying the movement of the index.

  Note that the change of the measurement date and time of the measurement data plotted in the graph area 310 is not limited to the index movement operation in the time axis area 320 but may be an input operation of a specific date and time. For example, the date and time corresponding to each of the indices 322 and 324 are displayed on the report output screen so that they can be edited, and when the date and time are edited through the operation unit 180, the measurement data corresponding to the edited date and time is displayed in the graph area 310. It can also be configured to.

  When the date / time change instruction is not detected in S107, the control unit 140 advances the process to S109 and determines whether or not an operation for selecting any of the event indices 326 has been performed. Here, the selection operation of the event index 326 may be an arbitrary operation according to the implementation, such as a press operation of the event selection button of the operation unit 180 other than a touch operation on the screen or a click operation with a mouse or the like.

  When an operation for selecting one of the event indicators 326 is detected, the control unit 140 advances the process to S111, acquires measurement data of the date and time corresponding to the selected event indicator from the storage unit 195, and stores it in the graph region 310. Plot. At this time, the control unit 140 draws the color of the figure connecting the plots with the color of the selected event index (that is, the color according to the event type).

  The measurement data corresponding to the event index 326 may be displayed only while the operation for selecting the index is continuously performed, or may be continuously displayed until an instruction to cancel the display is given. You may comprise. You may comprise so that a display may be cancelled | released automatically when predetermined time passes. When there are a plurality of event indicators 326 and one of them is selected and data is displayed, the original display may be canceled or left as it is. In the latter case, each time a different event index is selected, the number of figures displayed in the graph area 310 increases and the display becomes complicated. Therefore, the maximum simultaneous display number is determined in advance, and the maximum simultaneous display number is set. If it exceeds, the display of measurement data corresponding to the index with the oldest selection time may be canceled.

  If an operation such as movement or selection of the index displayed in the time axis region 320 is not detected in S107 and S109, the control unit 140 advances the process to S113, and whether or not an instruction to end report output is given through the operation unit 180. Determine. If the end instruction is detected, the control unit 140 ends the report output process and returns the screen display to the normal layout at the time of measurement. If the end instruction is not detected, the control unit 140 returns the process to S107.

  As described above, according to the present embodiment, by using the graph area in which the measurement values are plotted in a radar chart shape, even if the number of pieces of biological information to be compared simultaneously increases, the visibility of the biological information is not reduced. It makes it possible to easily grasp changes over time. Furthermore, it is possible to indicate the range of normal values for each biological information together with the measured values, and to understand whether each measured value is normal. In addition, by using the time axis region, it is possible to easily change or specify the measurement date and time of the measurement data to be compared.

(Modification)
In the above-described embodiment, the report output for comparing a plurality of types of biological information measured at two different dates and times for the same patient has been described. However, the comparison target is not limited to two dates and times, and the report output in the same format as in FIG. 3 may be performed for the biological information measured at three or more dates and times.

  Further, in the above-described embodiment, the measurement value information at a plurality of discrete dates and times can be obtained from the display of the graph area 310 except for the case where the graphic is continuously displayed during the movement operation of the index. Information on measured values during no period is not available. Therefore, the control unit 140 may present information regarding the measurement values that are not plotted, for example, by using a section between the plotted values of each axis.

  The carbon dioxide gas concentration (CO2) in FIG. 3 will be described as an example. A section between the 12/24 10:00 measurement value plot 3121 and the 12/26 10:00 measurement value plot 3141 on the axis is shown. Use. For example, it is conceivable that the color of the section is changed in accordance with the ratio of the measured values out of the normal range among the measured values obtained between the two dates.

Also, the density of the plot can be changed according to the frequency with which the same value as the plotted value is obtained. For example, in the case of carbon dioxide gas concentration, the higher the frequency at which the same value as the plot 3121 is obtained among the measurement values obtained between 12/24 10: 00 to 12/26 10:00, the more the plot 3121 It is conceivable to increase the color density or to increase the plot 3121 (increase the diameter of a circle centered on the plot 3121). The same effect can be given to the plot 3141.
By such a method, it is also possible to provide information on the measurement values obtained during the designated date and time without increasing the complexity of the display of the graph area 310.

  FIG. 4 is a diagram showing another format example of the graph area 310. FIG. 4 shows a state in which measured values at one date and time are plotted in order to facilitate explanation and understanding of the format. However, as in the example shown in FIG. A figure indicating the normal range can be added.

  The format of FIG. 4 plots measured values of specific biological information in a specific arrangement, so that not only the measured values of individual biological information but also a plurality of types of biological information that can be used as an index useful for diagnosis. It is possible to grasp the relationship visually.

  In the example of FIG. 4, the graph region 310 has axes orthogonal to each other that extend radially from the center in the vertical and horizontal directions. Then, four pieces of biological information of the heart rate (HR), systolic blood pressure (IBP_SYS), average blood pressure (MAP), and pulse pressure (PP) are plotted on the axis clockwise from the top. By placing the heart rate and systolic blood pressure on adjacent axes, the slope of the straight line 410 connecting the plots on the axis represents the shock index (SI) = HR / IBP_SYS. The shock index is an index relating to the amount of bleeding. For example, when the absolute value of the slope exceeds 1, there is a risk of considerable bleeding. For example, it is useful information during follow-up after surgery.

  When the heart rate and systolic blood pressure are arranged on two adjacent axes, the area of the right triangle 415 having the origin and the plotted point as the apex is half of double product (DP) = HR × IBP_SYS. . Since the double product is a measure of the heart load (myocardial oxygen consumption), the area of the right triangle 415 can also be used as a similar measure.

  On the other hand, when the heart rate and the pulse pressure (PP) are arranged on two adjacent axes, the area of the right triangle 420 having the vertex plotted as the origin is an index of arteriosclerosis. The pulse pressure is a value obtained as the amplitude of the pulse wave (difference between systolic blood pressure and diastolic blood pressure), and PP = SV / C using cardiac ejection volume (SV) and arterial compliance (C). It can be expressed as. Since the reciprocal of compliance (1 / C) corresponds to the arterial stiffness, the pulse pressure increases as the aorta stiffens.

  On the other hand, when cardiac output (CO) is used, since there is a relationship CO = HR × SV, PP × HR = (SV / C) × (CO / SV) = CO / C = CO × arterial stiffness. . Therefore, PP × HR (twice the area of the right triangle 420) is a measure of the degree of arterial stiffness, and the area of the right triangle 420 can be used as a similar measure.

  The mean blood pressure (IBP_MAP) is the product of total peripheral blood vessel resistance (TPR) and cardiac output (CO), and can be expressed as IBP_MAP = CO × TPR. That is, the average blood pressure increases as the hardening of the small artery progresses. Therefore, the area of a triangle with the heart rate, pulse pressure, and average blood pressure as the apexes can also be used as a measure of the degree of arteriosclerosis.

  The biological information monitor 100 according to the present embodiment performs report output by selecting one of a plurality of formats including the formats shown in FIGS. 3 and 4 by operating a key or a button included in the operation unit 180, for example. be able to.

(Other embodiments)
In the above-described embodiment, the configuration for outputting (displaying) a report on the screen has been described. However, for example, the report in a state displayed on the screen may be printed and output by a printer 190 on a recording medium such as paper. it can.

  In the above-described embodiment, the configuration using the report format of FIG. 3 or FIG. 4 has been described for the purpose of comparing measured values at two or more points on the time axis. However, the report format of FIGS. 3 and 4 may be used for plotting the measured values at one point on the time axis. For example, the report format shown in FIGS. 3 and 4 may be used on the real-time display screen of the biological information measured by the biological information monitor 100.

  The present invention can also be realized as a program that causes the report output processing of the above-described embodiment to be performed by one or more processors in a computer of the system or apparatus. Therefore, such a program and a computer-readable recording medium recording the program also constitute the present invention. Moreover, the report output process of the above-mentioned embodiment can also be implemented using hardware (for example, ASIC, programmable logic, etc.).
