Description

The present invention relates to a biological information output apparatus and method, and more particularly, to a biological information output apparatus and method serving as an index of arterial disease.
The present invention also relates to a biometric information report for presenting biometric information including at least a blood pressure value, and more particularly to a biometric information report that is easy to evaluate whether there is a risk of arterial disease.

  Conventionally, the ratio of blood pressure measured in the lower limbs and upper limbs (lower limb upper limb blood pressure ratio) is generally used as an index of vascular diseases such as arteriosclerosis. As the lower limb upper limb blood pressure ratio, for example, a systolic blood pressure ratio (ABI) measured at the upper arm and ankle, and a systolic blood pressure ratio (TBI) measured at the upper arm and toes are known. For example, when (lower limb blood pressure / upper arm blood pressure) ≦ 0.9 or less, it is used as an index for suspecting arterial stenosis of the lower limb.

  However, the lower extremity upper limb blood pressure ratio may show a normal value when arteriosclerosis is progressing throughout the body, so by using in combination with pulse wave velocity or pulse wave velocity (PWV), It has been proposed to use the lower limb upper limb blood pressure ratio as a more accurate index (see, for example, Patent Document 1).

JP 2000-316821 A

  However, in order to determine whether there is a suspicion of arterial disease, it is necessary to evaluate not only the ratio of blood pressure values as in ABI but also the blood pressure value itself.

● (first embodiment)

In the present embodiment, an example in which the present invention is applied to a biological information measuring apparatus capable of acquiring various biological information will be described. What is necessary is just to be acquirable by the method. For example, the already measured value may be acquired by reading from a storage device or the like, and in this case, it is not necessary to have a function of measuring a blood pressure value.

  The arithmetic control unit 10 controls the overall operation of the biological information measuring apparatus of this embodiment. The arithmetic control unit 10 is a general-purpose computer device having, for example, a CPU, ROM, RAM (including non-volatile RAM), and various interfaces (not shown), for example, a large-capacity storage device such as a built-in or external hard disk, an optical disk, or a ROM When the CPU executes the control program stored in, various operations described below are executed and controlled. Of course, not all may be processed by software, and at least a part thereof may be realized by hardware.

  The arithmetic control unit 10 controls the upper limb blood pressure control unit 201 and the lower limb blood pressure control unit 202, and the diastolic blood pressure Pd, the systolic blood pressure Ps in the upper limb (for example, the upper arm) and the lower limb (for example, the ankle or the toe) and The average blood pressure Pm is measured. From these measurement results, ABI (ratio between right or left ankle systolic blood pressure value and upper arm (representative) blood pressure value) and TBI (ratio between right or left footpad systolic blood pressure value and upper arm (representative) blood pressure value). ) May be requested.

  The arithmetic control unit 10 further detects a pulse wave signal supplied from the upper limb blood pressure control unit 201 and the lower limb blood pressure control unit 202 (if necessary, a heart sound signal or an electrocardiogram signal supplied from the heart sound detection unit 203 An electrocardiogram signal supplied from the unit 204 and a carotid artery wave, a hip artery wave, a popliteal artery wave, etc. supplied from the pulse wave detection unit 205 may be selectively used) and the blood vessel length between the measurement sites ( The pulse wave propagation velocity between the heart (aortic valve opening) —ankle, heart—foot toe, or cuff wearing site can be calculated using the previously obtained blood vessel length equivalent value.

  The upper limb blood pressure control unit 201 and the lower limb blood pressure control unit 202 are respectively connected to two cuffs connected via the hoses 21h and 22h using a pump, an exhaust valve, or the like (not shown) according to the control of the arithmetic control unit 10. 21R, L, and 22R, L rubber sac (21aR, 21aL, 22aR, 22aL) is pressurized / depressurized (blood-driven). The upper limb blood pressure control unit 201 and the lower limb blood pressure control unit 202 are also provided with sensors for detecting pulse waves propagating through the hoses 21h and 22h, such as pressure sensors (211R, L and 221R, L). The pulse wave propagating through the rubber sac and the hose is converted into an electric signal and output to the arithmetic control unit 10. Although FIG. 1 shows a configuration in which the upper limb blood pressure control unit 201 and the lower limb blood pressure control unit 202 are provided independently, they may be integrated. In the following description, when R and L are not added, such as cuff 21 and cuff 22, both R and L are collectively shown.

  The heart sound detection unit 203 supplies a heart sound signal of the subject detected using the heart sound microphone 23 to the calculation control unit 10. The heart sound signal is mainly used to determine the start time of the pulse wave in the heart.

  The electrocardiogram signal detection unit 204 acquires an electrocardiogram signal detected by the electrocardiogram electrodes 24 a and 24 b and supplies it to the arithmetic control unit 10. The electrocardiogram signal is acquired as necessary when performing a more comprehensive diagnosis.

  The pulse wave detection unit 205 supplies the pulse wave detected by the pulse wave sensors 25 a and 25 b, specifically, the carotid artery wave, the hip artery wave, and the popliteal artery wave to the calculation control unit 10. It should be noted that sensors similar to the pulse wave sensors 25a and 25b are arranged at the attachment parts of the cuffs 21 and 22 (including the case where they are built in the cuffs 21 and 22), and the pulse wave is detected from these pulse wave sensors. good.

  The arithmetic control unit 10 also includes a display unit 70 that can display and output various operation guidance, measurement results, and diagnostic indicators, a recording unit 75 that is an image forming apparatus such as a printer that can record and output measurement results and diagnostic indicators, Measurement results and diagnostic indicators are stored, for example, a storage unit 80 composed of a hard disk drive, a writable optical disk drive, a nonvolatile semiconductor memory, etc., a voice generation unit 85 capable of outputting voice guidance output and various notification sounds, a keyboard, An input / instruction unit 90 that includes a mouse, a button, a touch panel, and the like and enables input and instruction by the user is connected.

  In addition to this, a wired and / or wireless communication interface for communicating with other devices, a storage device using a removable medium, and the like may be provided. Further, the display unit 70 and the recording unit 75 may be separately connectable to the outside. That is, apart from the display unit 70 and the recording unit 75 built in the apparatus main body, an external display device having a larger display area and / or a larger display color, or an external recording device having a larger print area and / or a larger print color. May be connectable. Thereby, the miniaturization of the main body and the diversity of output can be realized at the same time. In this case, a known display interface and printer interface may be provided.

(Measurement process: Preparation before measurement)
A procedure and operation when performing measurement using the biological information output apparatus having such a configuration will be described. Here, a case where measurement with the highest accuracy is performed will be described. It is assumed that initial setting processing relating to device operation such as time setting is performed in advance.

  First, as a preparation stage, a cuff, a sensor, and the like are attached to the subject. Specifically, the upper limb cuff 21R / 21L is attached to the subject's right / left upper arm, and the lower limb cuff 22R / 22L is attached to the subject's right / left ankle or toe. Although the cuff attached to the ankle and the cuff attached to the toe are different in configuration, the cuff 22 for the lower limb will be described here. The cuffs 21 and 22 can be attached with a hook-and-loop fastener or the like.

  Further, the electrocardiographic electrodes 24a and 24b are attached to the left and right wrists, for example. A cream or the like is applied to the mounting site as is usually done for good detection. The attachment site of the electrocardiographic electrode can be changed according to the type of guidance to be acquired. When measuring the pulse wave at or near the blood pressure measurement site using a mechanism other than the cuff, for example, an individual pulse wave sensor, the pulse wave sensor is attached here.

  In addition, the heart sound microphone 23 is attached to a predetermined chest position of the subject (second II intercostal sternum edge) with a tape or the like. Further, a pulse wave sensor 25a is attached to the neck carotid artery pulsation site. Further, a pulse wave sensor 25b for the hip artery is attached to the buttocks as necessary.

  Next, personal information of the subject such as age, sex, height, and weight is input using the input / instruction unit 90. From this height value, the blood vessel length is obtained by a predetermined formula. In addition, the blood vessel length may be obtained by a predetermined formula by measuring and inputting the distance from the II intercostal sternum edge and the cuff 21 and the cuff 22 attachment site with a scale or the like. This completes the preparation before measurement.

(Measurement processing: pulse wave measurement)
When preparation for measurement is completed and, for example, a measurement start instruction is given from the input / instruction unit 90, the arithmetic control unit 10 first starts a pulse wave measurement process at or near the blood pressure measurement site. When performing pulse wave measurement using the cuff, the order can be arbitrarily set. First, the upper limb blood pressure control unit 201 is instructed to start pressurization to the upper right arm cuff 21R.

  The blood extremity control unit 201 for the upper limbs sends air to the cuff 21R to inflate the rubber sac 21aR. At this time, the pressure applied to the body surface by the cuff 21R (the cuff internal pressure detected by the pressure sensor 2111R) can be set to a low pressure within a range where the pulse wave can be detected, for example, a pressure lower than a general minimum blood pressure value. .

  A pulse wave propagates as a pressure wave of air from the rubber bag 21aR through the hose 21h and is detected by the pressure sensor 211R. This pulse wave is converted into an electric signal (in general, the pressure sensor itself converts the pressure into an electric signal and output), and the pulse wave signal obtained from the cuff 21R is output to the arithmetic control unit 10. The arithmetic control unit 10 records this pulse wave signal in the storage unit 80. When a predetermined amount of pulse wave having a sufficient amplitude is measured, the upper limb blood pressure control unit 201 opens the exhaust valve and exhausts the cuff 21R.

  Such a pulse wave measurement operation is executed for all cuffs simultaneously or sequentially to measure a pulse wave at or near the blood pressure measurement site. In addition, when performing pulse wave detection with a pulse wave sensor different from the cuff, pulse waves may be acquired from all sensors simultaneously or sequentially and recorded.

(Measurement process: blood pressure measurement)
Next, the arithmetic control unit 10 starts a blood pressure measurement process. Here, the order can be arbitrarily set, but first, the upper limb blood pressure control unit 201 is instructed to start pressurizing the upper right arm cuff 21R.

  The blood extremity control unit 201 for the upper limbs sends air to the cuff 21R, inflates the rubber sac 21aR, and compresses the attachment site. According to the compression, the pulse wave propagates from the rubber sac 21aR through the hose 21h as a pressure wave of air and is detected by the pressure sensor 211R. This pulse wave is converted into an electric signal (in general, the pressure sensor itself converts the pressure into an electric signal and output), and the pulse wave signal obtained from the cuff 21R is output to the arithmetic control unit 10.

  The arithmetic control unit 10 seems that the pulse wave detected by the pressure sensor 211R is sufficiently small and is not detected as a waveform, and the cuff wearing part is driven, or the cuff wearing part is sufficiently driven. Until the cuff pressure reaches a predetermined value, air is fed into the rubber sac 21aR by the upper limb blood-feeding control unit 201. Then, pressurization is stopped when the pulse wave becomes sufficiently small and is no longer detected as a waveform, or at a predetermined cuff pressure. The cuff pressure (internal pressure) at this time can be detected by the pressure sensor 211R. Then, the upper limb blood pressure control unit 201 is instructed to gradually decrease the cuff pressure.

  The upper limb blood pressure control unit 201 adjusts an exhaust valve (not shown) and starts recording the detected pulse wave signal while reducing the cuff at a constant rate by letting air escape from the rubber sac 21aR. Also, the cuff pressure is continuously detected by the pressure sensor 211R. During the decompression process, the pulse wave starts to be detected again, and then the cuff at the point where the amplitude of the pulse wave increases rapidly, the point where the maximum amplitude of the pulse wave is obtained, and the point where the amplitude of the pulse wave decreases rapidly. From the pressure, systolic blood pressure Ps, average blood pressure Pm, and diastolic blood pressure Pd are obtained. The cuff pressure can also be calculated using the value at the start of decompression, the decompression rate, and the decompression time. Such a blood pressure measurement method is known as an oscillometric method (volume pulse vibration method). When the diastolic blood pressure is obtained, the cuff is depressurized at once.

Such blood pressure measurement processing is similarly performed on the remaining cuffs 21L, 22R, and 22L, and the blood pressure measurement of the upper limb and the lower limb is completed.
The measured systolic blood pressure value, average blood pressure value, and diastolic blood pressure value are stored in the storage unit 80 in association with the pulse wave signal detected at the same site.

(Measurement processing: PWV measurement)
Although it is possible to create a report to be described later from the blood pressure and pulse wave measurement results described above, in this embodiment, in order to obtain another index useful for the diagnosis of arterial disease, other biological information Also measure. Here, first, the process moves to the PWV measurement process. When the carotid artery wave is detected using the pulse wave sensor 25 a, the arithmetic control unit 10 acquires these pulse waves via the pulse wave detection unit 205 and from the heart sound signal acquired via the heart sound detection unit 203. Then, the generation of a heart sound (for example, II sound) corresponding to the rise of the pulse wave is detected. Each of the pulse wave and the heart sound signal is subjected to appropriate processing such as A / D conversion and stored in the storage unit 80. And PWV is calculated | required as follows.
PWV = AF / (t + tc)
here,
AF: Vascular length from the second intercostal sternum edge to the cuff 22R attachment site (ankle or toe) t: Time difference from the rise of the carotid wave (or brachial pulse wave) to the rise of the ankle (or toe) pulse wave tc: Time difference from the rise of the heart sound II sound to the carotid artery wave (or brachial pulse wave) notch point.

When the pulse wave sensor 25a is not used, the estimated blood vessel length is determined from the difference between the distance from the heart (aortic origin) to the cuff 21R attachment site and the distance from the heart (aorta origin) to the cuff 22R attachment. And a value obtained by dividing this by the time difference between the rising point of the pulse wave measured by the cuff 21R attached to the upper arm and the rising point of the pulse wave detected by the cuff 22R may be referred to as PWV (also called baPWV). ). Or you may use the value calculated | required similarly from the time difference of the pulse wave measured at arbitrary two points, and the blood vessel length (or its conversion value) between measurement points as PWV.
When the PWV measurement is completed, the arithmetic control unit 10 releases the cuff by the upper limb blood pressure control unit 201 and the lower limb blood pressure control unit 202, stores the measurement result in the storage unit 80, and ends the measurement process.

  Note that, as described above, the case where blood pressure and pulse wave measurement is performed with the left and right upper arms and the left and right ankles / footpads has been described here, but in order to enjoy the effect of the report format described later that is characteristic of the present embodiment. In other words, blood pressure and pulse wave may be measured at at least two places in the living body. Also, PWV may be calculated for both the heart-ankle and the heart-toe, or may be calculated for each of the left and right sides. Further, PWVs such as heart (aortic origin) -upper arm, heart-knee, thigh-ankle, upper arm-wrist, etc. may be obtained.

(Calculation of vascular elasticity index)
Next, the arithmetic control unit 10 calculates a vascular elasticity index. As the vascular elasticity index, for example, values obtained by equations 1 to 5 shown in FIG. 2 can be used. In Expressions 1 to 5, k is a constant. Which formula is used to calculate the vascular elasticity index is determined in advance. Of course, it is possible to calculate two or more equations.

  The blood pressure values (maximum blood pressure Ps, average blood pressure Pm, and minimum blood pressure Pd) used in Equations 1 to 5 are ideally the blood pressure values at the center of the section where PWV is measured. Measurement values can be substituted. The blood pressure value at the central point can be estimated from, for example, a blood pressure measured at a site where a pulse wave is measured in order to calculate PWV, and the measured value and a previously calculated conversion formula. Further, as the PWV used for calculating the vascular elasticity index, the result of measurement at any of the heart-ankle and the heart-footpad (or between two other points) may be used.

  Note that it is preferable to store various measured biological information and calculated values such as PWV and vascular elasticity index in association with the personal information of the subject and the measurement date and time. For example, a folder or directory is created for each subject, and each time measurement is performed, a folder or directory for each measurement is further created in the subject's folder or directory, and the acquired blood pressure value, pulse wave signal, etc. It is possible to save it.

  Note that, as described at the beginning of the present embodiment, the present embodiment is an example in which the present invention is applied to a biological information measuring apparatus capable of acquiring various biological information, and thus other biological information in addition to blood pressure, Specifically, measurement of pulse waves, electrocardiograms, heart sounds, etc., and calculation processing of PWV and vascular elasticity index have been described. However, the biological information output device according to the present invention only needs to have a function of outputting a report in the format described below from the measurement result of the blood pressure values of the limbs.

  The simplest form of a biometric information output device capable of outputting a report in the format described below is a form in which software for performing the following report output is mounted on a computer device commercially available as a personal computer, for example. is there. In this case, the measurement result of the biological information including blood pressure can be acquired from a removable medium or a network. Also in this case, the report output may be performed on either a display built in or externally attached to the computer apparatus, or a printer connected directly or indirectly.

(Report output processing)
Next, report output processing in the above-described biological information output apparatus will be described with reference to the flowchart of FIG. Here, description will be made assuming that the data is output by the recording unit 75 which is a color printer, for example. However, the output may be performed not only on the display unit 70 but also on an external display device or an external output device as described above.

  The report output process may be performed automatically after the measurement is completed, or a list of subjects that have been measured in the past and stored in the storage unit 80 is displayed on the display unit 70 as a list, for example. It is also possible to output a measurement result for the subject selected by the instruction unit 90. Here, it is assumed that the measurement result for the subject selected from the list of subjects who have measured in the past is output.

  First, the arithmetic control unit 10 reads out personal information and measurement results of the selected subject from the storage unit 80 (step S101). Then, the read information is arranged in a predetermined display format and laid out in an output format described later (step S103). In this embodiment, blood pressure value plots on coordinate axes, which will be described later, generation of quadrangular sides with blood pressure values as vertices, generation and arrangement of indices representing normal ranges and correlations, and the like are performed in this step.

  When the layout is completed, the output destination, for example, a format that can be output by the recording unit 75 is converted (step S105). This format conversion includes, for example, resolution conversion according to the output destination (72 or 96 dpi for display, 400 to 600 dpi for printing, etc.), color conversion (conversion to monochrome, increase / decrease in the number of colors, etc.) , Reduction / enlargement, expansion to a bitmap, and the like. When the conversion into a format suitable for the output destination is completed, the converted data is output as report data to the output destination (step S107) and displayed or printed.

  In addition, when the pre-measured data is placed in a state where the biometric information output device can be acquired via a network or a removable storage medium, a report is output by a biometric information output device that does not have a biometric information measurement function. Also, the output can be performed by the same processing. That is, the biometric information output device first acquires list information (such as a subject name list) of measurement data and displays it on the display. Then, after the subject is selected via an input device such as a keyboard or a mouse, the same processing as in steps S101 to S105 described above is performed, and the result is output to a preset output destination such as a display or a printer. (Step S107). As a result, a similar report is displayed or printed.

(Biometric report format)
FIG. 4 is a diagram illustrating an example of a biological information report output by the biological information output apparatus according to the present embodiment. Here, only the report format of blood pressure measurement values characteristic of the present embodiment will be described, but it is possible to include at least one of the other measurement values described above in the report. Needless to say.

  The report has a blood pressure value presentation area 320 that is a two-dimensional area for presenting blood pressure values. Then, linear first to fourth axes 325 to 328 extending from the origin 321 in the upper right, upper left, lower left, and lower right directions with the approximate center of the blood pressure value presentation area 320 as the origin 321 are arranged. The first and second axes 325 and 326 are arranged so as to be symmetrical with respect to a straight line 345 that passes through the origin 321 and extends vertically, and similarly, the third and fourth axes are also aligned with the straight line 345. It arrange | positions so that it may become symmetrical with respect to it. The straight line 345 need not be shown in the actual report, but may be shown.

  In the example of FIG. 4, the first axis 325 and the third axis 327, the second axis 326 and the fourth axis 328 are each represented by one straight line, and these straight lines are orthogonal to each other. However, it is sufficient that the graph can be plotted on the axis of symmetry in at least the upper limb and lower limb units.

  In the report of the present embodiment, these first to fourth axes 325 to 328 and the blood pressure values measured by the extremities are associated and plotted. Specifically, the first axis 325 has a blood pressure value measured at the left or right upper limb, the second axis 326 has a blood pressure value measured at the right or left upper limb, and the third axis 327 has a blood pressure value measured at the right or left upper limb. The blood pressure value measured on the lower limb on the same side as the blood pressure value plotted on the second axis 326, the blood pressure value measured on the lower limb on the same side as the blood pressure value plotted on the first axis 325 on the fourth axis. Plot each.

In the example of FIG. 4, the blood pressure value A1 in the left upper limb (LB: Left Brachial) is indicated on the first axis 325, and the right limb (RB: Right Brachial) is indicated on the second axis 326. Blood pressure value B1 of the right lower limb (RA: Right Ankle) on the third axis 327, and left lower limb (LA: Left Ankle) on the fourth axis 328. Each blood pressure value D1 is plotted. The left and right measurement positions of the blood pressure values to be plotted can be interchanged, the blood pressure values at the upper right limb and the right lower limb on the first and fourth axes, and the blood pressure values at the left upper limb and the left lower limb on the second and third axes. May be plotted.
In FIG. 4, A1 to D1 are indicated by coordinate values in an orthogonal coordinate system in which the origin 321 is common and the line 345 is the y-axis.

  Although the positional relationship of the upper limbs and lower limbs can also be interchanged, it is unnatural to plot the blood pressure values in the upper limbs downward, so the blood pressure values in the upper limbs extend upward from the origin 321 unless there are special circumstances. Plot on the first and second axes 325, 326.

  The relationship between the vertical position and the horizontal position may be interchanged so that the blood pressure value of the upper limb is plotted on the right plane, and the blood pressure value of the lower limb may be plotted on the left plane. The blood pressure values of the upper right limb, the left upper limb on the fourth axis, the right lower limb on the second axis, and the left lower limb on the third axis are plotted. Similarly, the blood pressure value of the upper limb may be plotted on the left plane, and the blood pressure value of the lower limb may be plotted on the right plane.

  In the example of FIG. 4, the first to fourth axes 325 to 328 have a common scale with the origin as 0 (the scale itself may or may not be displayed). The common scale means that points at the same distance from the origin on each axis indicate the same value, and includes sections with different rate of increase (scale ratio) per unit distance (scale). It may be.

  In the report according to the present embodiment, one of the features is that the quadrangle 330 whose apexes are the blood pressure values plotted on the respective axes in this way is shown. By showing such a quadrangular shape, the interrelationship between blood pressure values of the limbs can be intuitively grasped from the quadrangular shape.

  That is, the inclination of the side A1B1 and the side C1D1 of the quadrangle 330 represents the magnitude of the difference between the left and right blood pressure values of the upper limb and the lower limb. In addition, the inclinations of the side B1C1 and the side D1A1 represent the magnitude of the difference between the blood pressure values of the upper and lower limbs of the right and left bodies. Therefore, the closer the quadrangle 330 to the line 345 is to be symmetrical, the more the left and right blood pressure values are more uniform, and the side A1B1 is longer than the side C1D1, that is, the upper base is longer than the lower base, A squeezed trapezoid indicates that stenosis in the lower limb is suspected.

  Thus, from the shape of the quadrangle 330, it is possible to grasp the relationship between the left and right blood pressure values and the relationship between the blood pressure values of the upper limbs and the lower limbs in an instant. Moreover, it is easy to grasp individual specific blood pressure values by reading the values of the respective vertices. Of course, a specific blood pressure value may be indicated by a numerical value in association with each plotted point.

(Simultaneous presentation of different blood pressure values)
When blood pressure is measured, the highest blood pressure value, the lowest blood pressure value, and the average blood pressure value are usually measured. In the above example, for ease of explanation and understanding, a report that presents one of these blood pressure values has been described. However, a plurality of blood pressure values may be shown in the same presentation area.
FIG. 5 is a diagram showing an example in which the systolic blood pressure value, the diastolic blood pressure value, and the average blood pressure value measured in each of the four limbs are presented according to the format of FIG. In FIG. 5, the average blood pressure value is represented by a quadrangle A2B2C2D2, and the minimum blood pressure value is represented by a quadrangle A3B3C3D3.

(Auxiliary indicator)
Various auxiliary indexes can be added to the basic biological information report described above.
(Indicator of normal range)
FIG. 6 is a diagram illustrating an example of a biometric information report to which an index indicating a normal range of other blood pressure values is added on the basis of the right upper limb blood pressure value. 6A, a circle 610 that passes through the coordinates (−b, b) of the right upper limb blood pressure value and is centered on the origin O, and in FIG. 6B, has the coordinates (−b, b) as a vertex. An example is shown in which squares 611 with the origin O as the center of gravity are added as indices. If other blood pressure values, particularly lower limb blood pressure values, fall within these indicators, stenosis of the lower limbs is suspected.
When the upper limb blood pressure value is used as the reference of the index, the higher one of the left and right upper limb blood pressure values is preferably used as the reference.

(Indicator that clearly shows the difference in upper limb blood pressure)
FIG. 7 shows the upper limb blood pressure values, that is, the blood pressure values plotted on the first axis 325 and the second axis 326, the coordinates corresponding to the coordinates of the higher blood pressure value being plotted on the other blood pressure value. It is a figure which shows the example of the biometric information report which added the parameter | index shown on the axis | shaft which is.
When there is a difference between the left and right upper limb blood pressure values, this index is presented for evaluation because there is a possibility that a blood circulation disorder may be suspected in the upper limb on which a low value is measured.

  FIG. 7 shows an example in which this index is applied when the left upper limb blood pressure value is lower than the upper right limb blood pressure value. The index 710 is a mark indicating coordinates corresponding to the higher blood pressure value, which is indicated on the axis on which the lower blood pressure value is plotted. A line 711 extending horizontally from the coordinate of the higher blood pressure value toward the index 710 may also be shown.

(If there is a blood pressure value that could not be measured normally due to unmeasured or impossible measurement)
When measuring blood pressure, due to reasons such as the cuff being worn incorrectly, or when normal measurements could not be made, or extreme measurements that would normally not be possible (these are said to be impossible to measure), or When the measurement itself is not made (unmeasured), the above-described quadrilateral cannot be drawn.

  In such a case, in the present embodiment, a point insufficient to draw the quadrangle 330 having the blood pressure value as a vertex is compensated, and the quadrangle 330 is drawn using the compensated point. The compensated point can be identified by changing the mark drawn on the axis so that it can be distinguished from the blood pressure value obtained by normal measurement.

FIG. 15 shows that the blood pressure value to be plotted on the first axis 325 among the blood pressure values plotted on the first axis 325 and the second axis 326 is not obtained because the blood pressure value to be plotted on the first axis 325 is not measured and cannot be measured. Shows the case where the blood pressure value of the right upper limb obtained by normal measurement plotted on the second axis is plotted on the first axis by using the blood pressure value obtained by normal measurement as measured on the left upper limb. .
In FIG. 15, a mark 1501 indicating the blood pressure value plotted on the first axis is “X”, and it is possible to identify a supplemented point that is different from other plotted values.

  FIG. 15 shows a case where the upper limb blood pressure value is compensated. Similarly, the lower limb blood pressure value is represented by the coordinate corresponding to the blood pressure value on the side where the blood pressure can be measured in the lower limb, on the other axis without the blood pressure value. This makes it possible to compensate for the lack of points for drawing a quadrilateral.

  In addition, it is possible to clearly indicate which value is used to supplement the point using characters, arrows, or the like. In addition, the line style (visual characteristics such as thickness, color, solid line / dotted line) of the rectangle 330 that touches the index 1501 (with the index 1501 as a start point or an end point) is changed to be different from others. Also good.

(Indicator for improving visibility)
In addition, an index for improving visibility can be added.
For example, character strings 341 to 344 that can visually identify the correspondence with each axis are added as an index indicating the measurement site of the plotted blood pressure value, or as shown in FIG. An image 350 representing the image may be added by a pattern indicating a silhouette or an outline. According to Fig.8 (a), it can grasp | ascertain intuitively that the blood pressure value plotted on the 1st-4th axis | shafts 325-328 is a blood pressure value on the left and right upper limbs. In order to make the correspondence between the axis and the blood pressure value clearer, a pattern in which both hands and / or both legs are expanded can be used.

  FIG. 8B shows an example in which coordinates indicating representative values on each axis are connected by lines in the same manner as the measured values. By clearly indicating the scale of the representative value in this way, an approximate value of the measured value can be grasped. In FIG. 8B, the scale of the representative value is shown by a quadrangle having each coordinate as a vertex, but it may be expressed using a circle or an ellipse passing through each coordinate.

(Indicator indicating the degree of suspected stenosis and suspected stenosis)
As described above, it is possible to easily grasp whether or not there is a stenosis due to the shape of the quadrangle 330. In addition to the quadrangle 330, an index indicating whether or not there is a stenosis, An indicator that more specifically indicates whether stenosis is suspected can be added.

First, the barycentric position of the quadrangle 330 can be added to the report as an index indicating the degree of suspected stenosis. As described above, as the ratio of the blood pressure values of the upper limbs and lower limbs approaches 1, and the difference between the left and right blood pressure values decreases, the quadrangle 330 becomes square and the center of gravity approaches the origin. Conversely, stenosis is suspected as the position of the center of gravity of the square 330 is further away from the origin. FIG. 9A shows an example of a report in which the center of gravity of the quadrangle 330 is indicated by a mark 910 (here, x). In the present embodiment, the position of the center of gravity G (x, y) is
x = (− right upper arm blood pressure + left upper arm blood pressure−right ankle blood pressure + left ankle blood pressure) / 3√2
y = (upper right arm blood pressure + left upper arm blood pressure−right ankle blood pressure−left ankle blood pressure) / 3√2
Asking.

  FIG. 9B shows an example of a report in which an arrow 911 from the origin to the center of gravity 910 is further added as an index in order to more clearly show the position of the center of gravity and the distance from the origin. By adding such an arrow, the suspicion of stenosis can be expressed by the length of the arrow.

  As another example of an index using the position of the center of gravity, an index indicating a site where stenosis is suspected can be added. This utilizes the fact that the even-numbered direction of the center of gravity represents a stenosis-proposed part. Further, since the distance between the pair of centroid positions and the origin corresponds to the distance between the centroid position and the origin, the magnitude of the distance from the origin to the pair represents the degree to which stenosis is suspected.

FIG. 10A shows an example of a report in which an arrow extending from the origin in the direction of the even number of the center of gravity position 910 of the quadrangle 330 is added as an index indicating the degree of suspected stenosis.
In FIG. 10A, the meaning of the index is emphasized by adding an arrow extending to a position that is a predetermined multiple (10 times here) of the even number. FIG. 10B shows the simultaneous presentation of a plurality of blood pressure values explained in FIG. 5, the index 610 indicating the normal range explained in FIG. 6A, the maximum blood pressure value, the minimum blood pressure value, and the average blood pressure value. The example of the report which applied combining the gravity center position 910 and the arrow 915 extended from an origin to the position of predetermined multiple of the even number of each gravity center position is shown.

(ABI index)
11 and 12 are diagrams illustrating examples of reports to which an index indicating the size of ABI is added. In the example of FIG. 11, a combined vector 380 of a vector extending from the origin to the right (or left) upper limb blood pressure value coordinate and a vector extending from the origin to the right (or left) lower limb blood pressure value coordinate is added as an index representing the size of ABI. doing.

That is, if the angle between the vector 380 and the x axis 346 of the xy coordinate system having the common origin 321 is θ (positive counterclockwise),
θ [°] = tan −1 (1 / ABI) −45
It is.

11A shows the case where ABI = 1.0, FIG. 11B shows the case where ABI = 1.5, and FIG. 11C shows the case where ABI = 0.5. Θ = 0, θ = −, respectively. 11.31, θ = 18.43.
In the example of FIG. 11, since the index is a composite vector, the index becomes longer as the blood pressure value is larger.

Similarly, FIG. 12 uses a vector extending from the origin as an index, but the angle θ and how to determine its size are different from the example of FIG.
In the example of FIG.
θ [°] = tan −1 (1 / ABI−1)
It is.

The end point of the vector is defined as the midpoint of a straight line connecting the intersection of the y-axis 345 and a straight line extending horizontally from the higher coordinate of the upper limb blood pressure value and one of the coordinates of the lower limb blood pressure value. . By this method, it is possible to realize an index whose angle changes by ABI.
FIGS. 12A to 12C show the indicators 390 when the ABI is 1.0, 1.5 and 0.5, as in FIGS. 11A to 11C.

FIG. 13 shows an example in which the biological information report of the present embodiment is applied to a comprehensive report including other measurement results. In FIG. 13, the biological information report of the present embodiment is shown in an area indicated by 400. In the example of FIG. 13, the report of FIG. 5 presenting the systolic blood pressure value, the diastolic blood pressure value, and the average blood pressure value includes the representative scale index of each axis, the pattern of the human body, and the center of gravity of the rectangle formed by the systolic blood pressure value Various indices such as a position and an arrow extending from the origin in the direction of the even position of the center of gravity position are applied.
Note that various indexes can be used in appropriate combinations, and combinations other than those shown in FIG. 13 may be used.

  Thus, according to the present embodiment, blood pressure values measured by the extremities are plotted on the linear first to fourth axes extending from the origin in the upper right, upper left, lower left, and lower right directions, and these are plotted. By showing a quadrangle with the blood pressure value as the apex, it is easy to grasp specific measurement values at individual sites, and the interrelationship between the blood pressure values of the limbs can be intuitively grasped from the quadrilateral shape. . Therefore, it is very useful as an index for judging whether or not there is a possibility of arterial occlusion and the extent of the occlusion site and degree.

● (Second Embodiment)
Next, a biological information output apparatus according to the second embodiment of the present invention will be described. Except for the format of the report to be output, it may be the same as that of the first embodiment, so only the report output format characteristic of this embodiment will be described.

  In the first embodiment, the first axis 325 and the third axis 327, the second axis 326 and the fourth axis 328 are each a linear straight axis scale and / or direction between the upper limb and the lower limb. It is characterized by making it different.

  As described above, the inclination of the two vertical sides forming the quadrangle 330 is determined by the magnitude relationship between the upper limb blood pressure value and the lower limb blood pressure value. For example, when the inclination of the side B1C1 is negative, the right lower limb (ankle) blood pressure is determined. Value / upper right limb (upper arm) blood pressure value <1. Since this ratio is ABI itself, it is possible to suggest the value of ABI by the inclination of the vertical side of the rectangle 330.

  Based on this idea, the scale and inclination of the axis (the direction from the origin or the angle with the line 345 so that the inclination of the vertical side of the quadrilateral is divided into positive and negative with the abnormal ABI value as the boundary. Can also be adjusted). This also means that when the relative relationship of blood pressure values measured in the left upper limb, upper right limb, left lower limb, and right lower limb is in the normal range, the scale and inclination of the shaft are adjusted so that the quadrilateral is substantially square. Can do. By making such an adjustment, it is possible to evaluate whether or not stenosis of the lower limb is suspected only by looking at the inclination of the vertical side of the square 330.

Specifically, when the lower limb blood pressure value / upper limb blood pressure value is equal to a certain threshold value (for example, 0.9), the side connecting these blood pressure values is parallel to the line 345 (inclination is infinite). The axis direction and / or scale may be adjusted. More specifically, the inclination and / or scale of the axis may be adjusted so that the horizontal components of the plotted blood pressure value coordinates are equal.
For example, in the example of FIG. 4, it is assumed that such adjustment is performed based on the upper right limb blood pressure value and the right lower limb blood pressure value (or the left upper limb blood pressure value and the left lower limb blood pressure value). The upper right limb blood pressure value is assumed to be 120 mmHg.

  In this case, the above-described control can be realized by changing the scale and inclination (direction) of the third axis 327 for plotting the right lower limb blood pressure value as shown in FIG. FIG. 14A shows a case where the scale is changed without changing the inclination of the shaft. That is, when the blood pressure value of the upper limb is 120, the value represented by the third axis at the position where the straight line extending directly from the coordinates intersects the third axis 327 is 108 obtained by multiplying 120 by the threshold 0.9. Then, the scale of the scale of the shaft 327 is changed. As a result, when the lower limb blood pressure value is less than 108, the slope of the side B1C1 becomes negative, so it can be evaluated that there is a suspicion of lower limb stenosis from the quadrangular shape.

Further, the same control can be performed by changing the inclination of the shaft without changing the scale of the shaft. FIG. 14B shows a situation similar to FIG. 14A in which the inclination β of the third axis 327 is made larger than the inclination α of the second axis 326, so that The increase rate of the x-axis component of the point is made larger than that of the second axis 326, and the same control is realized without changing the scale.
The control may be performed for the upper limb blood pressure value axis with the reference blood pressure value as the lower limb blood pressure value. Further, both axes may be adjusted, or tilt adjustment and scale adjustment may be combined.

  As described above, the biometric information output device according to the present embodiment has an effect that the evaluation based on the quadrangular shape is easier than the biometric information report in the first embodiment. Also in this embodiment, it is possible to present a plurality of blood pressure values as shown in FIG. 5, and it is also possible to apply various combinations of auxiliary indexes described in the first embodiment as appropriate. Needless to say.

(Third embodiment)
As an index indicating the degree of stenosis suspicion or the site where stenosis is suspected, the difference between the blood pressure values of the upper and lower limbs or the magnitude of the ratio and an index focusing on ABI can be used together.
FIG. 16 is a diagram for explaining an index adding method according to the present embodiment. FIG. 16 (a) is similar to FIG. 6 (b), using the upper right limb blood pressure value as a reference, the index indicating the normal range of other blood pressure values, the coordinates (−b, b) as the apex, and the origin O as The example of the biometric information report which added the square 611 made into a gravity center as a parameter | index is shown.

In the present embodiment, the following two conditions are used as additional conditions for an index indicating the degree of stenosis suspected or the site where stenosis is suspected.
(1) When the blood pressure difference between the left and right upper limbs is greater than or equal to a predetermined value (for example, 20 mmHg or more) (2) When either the left or right ABI is less than 1.00 If any of these conditions is met, an index is added to the report To do.

  In the present embodiment, when the condition (1) is satisfied, the origin O is the starting point on the first or second axis 325 or 326 corresponding to the upper limb from which the lower blood pressure value is measured, An arrow having a length that has a positive correlation with the magnitude of the blood pressure difference is added as an index indicating the degree of suspected stenosis in the upper limb or a site suspected of stenosis.

  FIG. 16B shows a state in which an index 612 indicating a range satisfying the condition (1) is added to FIG. For example, when the condition is whether the absolute value of the left-right blood pressure difference is 20 mmHg or more, it is 20 mmHg from the reference upper limb blood pressure value (usually the higher blood pressure value, here the upper right limb blood pressure value). Add a square corresponding to the lower value.

In the example of FIG. 16B, since the left upper limb blood pressure value exists inside the index 612, the condition (1) is satisfied.
In this case, an arrow extending outward from the origin O along the first axis 325 is added as an index. In addition, the length of the arrow is made longer as the difference between the left and right blood pressures is larger (the situation is suspected to be worse). Specifically, when the distance from the origin O to the vertex P is L,
L × (1—lower limb systolic blood pressure value / left / right upper limb systolic blood pressure value + α)
As the length can be determined. However, α is a positive constant less than 1. The constant α is for adjustment so that the maximum value of the blood pressure difference that can be actually observed is expressed by a sufficiently long index.

Alternatively, the realistic maximum value of the values of (lower left upper limb systolic blood pressure value / left and higher upper limb systolic blood pressure value) assumed when the condition (1) is satisfied at the origin O and the vertex P. And the minimum value may be assigned, and the length may be determined according to the actually obtained value.
In addition, as shown in FIG. 16, when the mark ([LB], [RB], [RA], [LA]) indicating the part exists at the apex, the axis is closest to the apex (for example, P ′). A minimum value may be assigned to.

  FIG. 16C shows an example of the index 620 added when the condition (1) is satisfied. By the index 620, it is intuitively determined by the length (size) of the index that the blood pressure of the left upper limb is significantly lower than the blood pressure value of the upper right limb and how much stenosis is suspected (how much the difference is). Can be grasped.

  Next, addition of an index according to condition (2) will be described. Unlike condition (1), condition (2) can be determined independently on the left and right sides, and here it will be described as being determined independently on the left and right, but condition (2) is determined only for the right and left ABIs. You may do it.

Condition (2) is a condition that ABI is less than 1.00. Therefore, when the ABI of the right half or the ABI of the left half is less than 1.00, a longer (larger) index is added to the corresponding lower limb axis as the value is smaller.
For example, when the ABI of the left half is less than 1.00, an index similar to that when the condition (1) is satisfied is added on the fourth axis 328 corresponding to the left lower limb.

In addition, the length of the index is assigned to the origin O and the vertex Q (or R) by 1 and an assumed realistic minimum value (for example, 0.5), and the length is determined according to the actually obtained value. Can be determined. However, in this case, when the value of ABI is close to 1, the index is short and difficult to discriminate. Therefore, when the value is close to 1, an index corresponding to a value lower than the actual value is used.
For example, when 1.00>ABI> 0.9, an index is added as ABI = 0.9. At this time, the indicator may be visually clarified by, for example, a dotted line.

  In FIG. 16 (c), the ABI of the right half is 1.00 or more, but the ABI of the left half is less than 1.00, and is outward from the origin O on the fourth axis 328 corresponding to the left lower limb. An arrow 630 extending to is added.

  Note that it is only necessary to finally add an index (620 or 630) based on the conditions (1) and (2) to the report, and an index 611 indicating the normal blood pressure range and an abnormal range of the difference between the left and right blood pressure values are indicated. The indicator 612 may or may not be added to the final report.

FIG. 17 is a diagram showing a modification of the present embodiment, in which the indicators 611 and 612 are circular indicators as shown in FIG. FIGS. 17A to 17C show states corresponding to FIGS. 16A to 16C, respectively.
In FIG. 17, since the plotted blood pressure values are different from those in FIG. 16, the positions and lengths of the finally added indices are different, but the indices 635 and 640 are obtained by the method described with reference to FIG. It is added. In the example of FIG. 17, ABI of the right half is low, and the blood pressure of the left upper limb is lower than the blood pressure of the right upper limb by a predetermined value or more.

  As described above, in this embodiment, as the index indicating the degree of stenosis suspicion and the site where stenosis is suspected, the magnitude of the difference between the blood pressure values of the left and right upper limbs and the index focusing on ABI are added together. It is possible to instantly grasp the suspected part and a guide to its extent.

  The index described in this embodiment can be added to a report in any format described in the first and second embodiments described above. For example, a scale of representative values of the human body pattern and axes as shown in FIG. 8 may be added, or not only the systolic blood pressure value but also the diastolic blood pressure value and the average blood pressure value may be plotted. It can also be used in combination with other additional indicators.

18 plots the systolic blood pressure value 641, the average blood pressure value 642, and the diastolic blood pressure value 643 in the report format shown in FIG. 8B, and the blood pressure centroid 645 described in FIG. 9 and the index 651 of this embodiment. It is a figure which shows the example which applied -653.
FIG. 19 shows an example in which the biological information report of FIG. 18 is applied to a comprehensive report including other measurement results. In the example of FIG. 19, since the ABI of the left half is 0.78, the index 660 according to this embodiment is added. Further, more information than the comprehensive report shown in FIG. 13 is shown, such as an estimated value of blood vessel age and a history of measured values.

● (Other embodiments)
The report output process in each embodiment described above can also be executed by a computer device that reads out these values from, for example, a storage device in which previously measured blood pressure values are stored and outputs a report of the above-described format. . Therefore, it goes without saying that a program for causing a computer apparatus to execute the report output processing in each of the above-described embodiments or a computer-readable recording medium storing the program also constitutes the present invention.

  In addition, an area for printing out the above-described biological information report, for example, the first to fourth axes in advance, the human body pattern and the scale of the representative values shown in FIG. 8, characters 341 to 344 in FIG. A recording medium such as a printing paper having an area printed with at least one of the above also constitutes the present invention.

  The blood pressure measurement method itself is not limited, and the blood pressure value may be measured by a method other than the oscillometric method, for example, a method using Korotkoff sound, ultrasonic waves, light, or an invasive method.

  It is also possible to configure the display format of the various reports described above and the measurement results included in the report so that the user can select them, or to change the scale of the graph so that the user can change them.
