An embodiment of the present invention will be described below with reference to the drawings. §1. First Embodiment [Outline of Embodiment] It is well known that a human condition repeats a cycle of excitement and sedation according to a regular rhythm with a cycle of one day. One of the means for grasping this rhythm from outside the body is a pulse wave. Pulse waves are measured in an invasive or non-invasive manner. Methods for noninvasively obtaining a pulse wave include a method for obtaining a change in lateral pressure of a blood vessel accompanying the ejection of blood from the heart and a method for obtaining a change in blood volume in a blood vessel. In addition, as a specific means for detecting a pulse wave, in addition to a commonly used pressure sensor, a sensor using light such as visible light and near infrared, a sensor using sound such as audible sound and ultrasonic wave, and a sensor using electromagnetic wave can be considered. ing.

In the present embodiment, a pulse wave is measured by pressing a pressure sensor attached to a wristwatch against a radial artery, and some measured amounts obtained from the pulse wave are used as indicators of a health condition. . Although details will be described later, specific examples of these measured amounts include LF, HF, RR50, and pulse. In this embodiment, such information is collected every fixed time every day. Then, the moving average of the measured amount in the past several days, the measured value at the present time, and the like are displayed on the wristwatch, and the subject can grasp his or her own health condition from the display result. Further, by displaying the transition of these measured amounts, it is possible to know about recent changes in the health condition.

By the way, among the information described above, LF, H
F and RR50 are, as it were, information on pulse wave "fluctuation". Hereinafter, such information will be described. The pulse does not need to be particularly explained. A. LF and HF In an electrocardiogram, the time interval between the R wave of one heartbeat and the Rwave of the next heartbeat is called an RR interval. The RR interval is a numerical value serving as an index of the autonomic nervous function in the human body. FIG.
Shows heartbeats in an electrocardiogram and RR intervals obtained from waveforms of these heartbeats. As can be seen from the figure, according to the analysis of the measurement results of the electrocardiogram, it is known that the RR interval varies with time.

On the other hand, the fluctuation of the blood pressure measured in the radial artery and the like is defined as the fluctuation of the systolic blood pressure and the diastolic blood pressure for each beat, and corresponds to the fluctuation of the RR interval in the electrocardiogram. FIG. 3 shows the relationship between the electrocardiogram and the blood pressure. As can be seen from this figure, the systolic and diastolic blood pressures per beat are the maximum of the arterial pressure at each RR interval,
And the local minimum seen just before the maximum.

By performing a spectrum analysis of the heart rate variability or the blood pressure variability, it is understood that these variances are composed of waves of a plurality of frequencies. These are classified into the following three types of fluctuation components. -HF (High Frequency) component, which is a fluctuation that matches respiration-LF (Low Frequency), which fluctuates in a cycle of about 10 seconds
Component ・ Trend that fluctuates at a frequency lower than the measurement limit (Tren
d)

For each of the measured pulse waves, the RR interval between adjacent pulse waves is determined, and the obtained discrete value of the RR interval is determined by an appropriate method (for example, cubic spline interpolation).
(See FIG. 2). Then, by performing FFT (Fast Fourier Transform) processing on the interpolated curve and performing spectrum analysis, the above-mentioned fluctuation component can be extracted as a peak on the frequency axis. FIG. 4A shows a fluctuation waveform of the measured RR interval of the pulse wave, and a waveform of each fluctuation component when the fluctuation waveform is decomposed into the three frequency components. FIG. 4B shows the result of spectrum analysis of the fluctuation waveform of the RR interval shown in FIG. As can be seen from this figure, around 0.07 Hz,
Peaks are seen at two frequencies around 0.25 Hz. The former is the LF component and the latter is the HF component. Note that the trend component is below the measurement limit and cannot be read from the figure.

The LF component represents the degree of the sympathetic tone, and the greater the amplitude of this component, the greater the tone. On the other hand, the HF component represents the degree of parasympathetic tone, and the greater the amplitude of this component, the more relaxed the component. Since there are individual differences in the amplitude values of the LF component and the HF component, when this is taken into account, the amplitude ratio of the LF component and the HF component is “LF / HF”.
Is useful for estimating the degree of tension of the subject. LF mentioned above
From the characteristics of the component and the HF component, the higher the value of “LF / HF”, the higher the degree of tension, and the smaller the value of “LF / HF”, the lower the degree of tension and relaxed.

B. RR50 RR50 is defined as the number of absolute values of the RR interval of two consecutive heartbeats that have changed by 50 milliseconds or more in the measurement of a pulse wave for a predetermined time. It has been found that the larger the value of RR50, the more sedated the subject is, while the smaller the value of RR50 is, more excited.

[Structure of Embodiment] FIG. 1 is a block diagram showing the structure of a health condition analyzing apparatus according to this embodiment. A user (subject) of this device wears a wristwatch 20 shown in FIG. 5, and the present device is incorporated in this wristwatch 20. In FIG. 1, a CPU (Central Processing Unit) 1 is a central unit that controls each circuit in the health condition analyzing apparatus, and its function will be described in the section of operation described later. A ROM (read only memory) 2 stores a control program and control data for the CPU 1. The temporary storage memory 3 is a kind of RAM (random access memory) and is used as a work area when the CPU 1 performs an operation.

The pulse wave detector 4 constantly measures the pulse wave in the radial artery of the user, and outputs the measurement result as an analog signal. A / D (analog / digital) converter 5
Converts the analog signal into a digital signal and outputs it. The data memory 6 is a non-volatile memory composed of a battery-backed RAM or the like. The data of the pulse wave fetched from the A / D converter 5 by the CPU 1, LF, HF, "LF" / H
F ", RR50, pulse rate and the like are stored.

The clock circuit 7 has a mechanism for generating a time to be displayed on the wristwatch 20 and for interrupting the CPU 1. That is, a specific time is detected or an interrupt signal is sent to the CPU 1 when a predetermined time has elapsed according to the designation of the CPU 1. Various buttons (details will be described later) provided on the wristwatch 20 are connected to the operation unit 8, and when these buttons are pressed down, the type of the button is output. The display 9 is a display device corresponding to various display units (details will be described later) provided on the wristwatch 20. The display control circuit 10 receives the display information created by the CPU 1 and assembles display data to be sent to the display 9 from the display information.

On the other hand, the wristwatch 20 shown in FIG. 5 is a timepiece having two modes, a "normal use mode" used as a normal timepiece and an "analysis mode" displaying a pulse wave analysis result. Reference numeral 21 denotes a body of the wristwatch,
A time display unit 22 and a graphic display unit 23 are provided on the upper surface. The time setting button 2 is located on the right side.
4. A mode switching button 25 and a display switching button 26 are attached.

The time display section 22 always displays the current time sent from the CPU 1. In the graphic display unit 23, the date, the day of the week, and the like are displayed in the normal use mode, and the analysis result of the pulse wave is displayed in a graph in the analysis mode. The time setting button 24 is a so-called crown,
Used for time adjustment and alarm setting. The mode switching button 25 is a button for switching between the normal use mode and the analysis mode, and switches between the normal use mode and the analysis mode each time the button is pressed. When the power is turned on, it is initialized to the normal use mode.

The display switching button 26 is used to switch display contents on the graphic display unit 23 in the analysis mode. The graphic display unit 23 can display any one of the following pulse wave analysis results in a graph. Moving average and current value of "LF / HF" Moving average and current value of LF and HF Moving average and current value of RR50 Moving average and current value of pulse rate Transition of "LF / HF" in past predetermined period In past predetermined period LF and HF Transition of RR50 in the past predetermined period Transition of pulse rate in the past predetermined period

Each time the display switching button 26 is pressed,
Are sequentially displayed on the graphic display unit 23. When the graph is displayed, the display switching button 2
When the user presses the button 6 only once, the graph is displayed again. In this embodiment, the value of the moving average is calculated based on the measured amount for the past week,
The predetermined period is also one week.

Reference numeral 27 denotes a pressure sensor, and reference numeral 28 denotes a fixture. These two components constitute the pulse wave detector 4 shown in FIG. The pressure sensor 27 is the mounting fixture 2
8, and the attachment 28 is slidably attached to a watch band 29. Watch 2
By attaching 0 to the wrist, the pressure sensor 27 can be pressed against the radial artery with an appropriate pressure. Here, the pressure sensor 27 is constituted by a strain gauge or the like, and terminals (not shown) provided at both ends of the pressure sensor 27.
From this, a pulse wave signal representing the radial artery waveform is obtained in an analog amount. This pulse wave signal is transmitted to the A / D converter 5 of FIG. 1 via a signal line (not shown) embedded in the watch band 29.

[Operation of Embodiment] Next, the operation of the health condition analyzing apparatus having the above configuration will be described. In order to measure the pulse wave at predetermined time intervals (for example, two hours), the CPU 1 causes the clock circuit 7 to generate an interrupt signal at, for example, “every two hours from midnight” when power is turned on. To

(1) Measurement and Analysis of Pulse Wave For example, when the clock circuit 7 generates an interrupt signal to the CPU 1 at 2:00 pm, the CPU 1 executes a pulse wave capturing process for a predetermined time (for example, 30 seconds). Therefore, first, the CPU 1 instructs the clock circuit 7 to monitor the time for 30 seconds. By the way, the pulse wave detection unit 4 constantly measures the pulse wave of the radial artery of the user, and the measurement result is A
The signal is converted into a digital signal by the / D converter 5 and output. The CPU 1 reads this digital signal and stores it in the data memory 6 together with the current time (2:00 pm) read from the clock circuit 7. The CPU 1 repeats the fetching process, but stops the process when an interrupt signal is sent from the clock circuit 7 after 30 seconds have elapsed. By the above processing, the waveform of the pulse wave for 30 seconds is accumulated in the data memory 6.

B. Analysis of Pulse Waveform Next, the CPU 1 analyzes the waveform of the pulse wave stored in the data memory 6 to determine LF, HF, “LF / HF”, RR5
0, calculate the pulse rate. a. Calculation of RR Interval CPU 1 extracts the maximum point from the waveform of the pulse wave. For this purpose, first, the CPU 1 performs time differentiation on the pulse wave waveform. Next, the time at which the time differential value is zero is obtained, and all the times at which the waveform takes extreme points are obtained. Subsequently, whether the extreme point at each time is the maximum or the minimum is determined from the slope (that is, the time differential value) of the waveform near the extreme point. For example,
For a certain pole, a moving average of the slope of the waveform is calculated for a predetermined time period before the pole. If the moving average is positive, it is understood that the pole is maximum, and if it is negative, it is minimum.

Next, for each of the extracted maximum points, the CPU 1 finds the minimum point existing immediately before the maximum point. Then, the amplitude of the pulse wave at the local maximum point and the local minimum point is read from the data memory 6, and the amplitude difference between them is obtained. If the difference is equal to or greater than a predetermined value, the time at the maximum point is set as the peak of the pulse wave. Then, the peak detection processing is performed on all the pulse wave waveforms obtained within the measurement period. Then, based on the times of two adjacent peaks, a time interval (corresponding to an RR interval) between them is calculated.

B. Calculation of LF, HF, and “LF / HF” Since the values of the RR intervals obtained above are discrete on the time axis, interpolation between adjacent RR intervals is performed by an appropriate interpolation method, and FIG. A curve as shown in a) is obtained. Next, when an FFT (fast Fourier transform) process is performed on the interpolated curve, a spectrum as shown in FIG. 4B is obtained. Therefore, a local maximum determination process similar to that performed on the pulse wave waveform is applied to obtain the local maximum value in this spectrum and the frequency corresponding to the local maximum value. The maximum value obtained in the low frequency region is defined as the LF component, and the maximum value obtained in the high frequency region is defined as the HF component. The amplitude of each component is obtained, and the amplitude ratio “LF / HF” is calculated.

C. Calculation of RR50 Next, the CPU 1 sequentially calculates the time difference between adjacent RR intervals based on the RR interval obtained as described above, and checks whether the time difference exceeds 50 milliseconds for each of them. Then, the number corresponding to this is counted as RR50. d. Calculation of Pulse Rate Next, the CPU 1 converts the peak number of the pulse wave observed during one measurement period into the pulse rate in one minute as the pulse number. e. Storing in the data memory 6 Finally, the amplitude of LF, the amplitude of HF, "LF / HF", R
R50, each value of pulse rate, pulse wave measurement time (2:00 pm)
Together with the data memory 6.

(2) Display of Measurement Result When the user presses the mode switching button 25 of the wristwatch 20, the mode is switched from the normal use mode to the analysis mode. Upon receiving a notification that the mode switching button 25 has been pressed from the operation unit 8,
The CPU 1 instructs the display control circuit 10 to erase the graphic display unit 23. Thereby, the display of the date and the day of the week on the graphic display unit 23 is cleared.

A. Next, the CPU 1 performs measurement of the pulse wave and analysis of the state of the living body based on the same procedure as the process of “(1) Measurement and analysis of pulse wave” described above. That is, the waveform of the pulse wave is fetched into the data memory 6 for only 30 seconds, the waveform of the fetched pulse wave is analyzed, and the LF, HF, "L"
F / HF ", RR50, and pulse rate are calculated. Then, these values are stored in the temporary storage memory 3 (for example).

B. Interpolation Processing Next, the CPU 1 obtains the current time from the clock circuit 7 and
The pulse wave measurement time before and after the time is obtained. As described above, since the measurement time of the pulse wave is every two hours from midnight every day, for example, if the current time is 1:30 pm,
The pulse wave measurement time before and after is exactly at noon and 2:00 pm.
Then, for example, for each day of the past week, LF, HF, LF / HF, RR50, measured at noon and 2 PM
The value of the pulse rate is read from the data memory 6. And L
F, HF,. . . , The current value is estimated by interpolating the values at noon and 2:00 pm. Then, the CPU 1 outputs LF, HF,. . . The average value for one week is calculated for each of the above. Note that, depending on the interpolation method, information over a wider range than the time immediately before / after is required. In such a case, the necessary information is read out from the data memory 6 as appropriate and interpolation is performed.

C. Graphic Display First, a bar graph as shown in FIG. 6 is created from the moving average value of “LF / HF” and the current value of “LF / HF” at the present time (1:30 pm). When the display information of this graph is sent to the display control circuit 10, the average value and the current value of "LF / HF" in the past week are displayed on the graphic display section 23 of the display 9 (first screen). Thereafter, each time the user presses the display switching button 26, the CP
U1 creates display information for a graph described below and causes the graphic display unit 23 to display the information in order.

First press (second screen) As shown in FIG. 7, the average value and current value of LF in the past week and the average value and current value of HF in the past week are displayed as bar graphs. . Second press (third screen) As shown in FIG. 8, the average value and the current value of RR50 in the past week are displayed in a bar graph.

Third press (fourth screen) As shown in FIG. 9, the average value and the current value of the pulse rate in the past week are displayed in a bar graph. 4th press (5th screen) Based on the value of “LF / HF” for the past week,
A line graph shown at 0 is displayed. -Fifth press (6th screen) Fig. 1 based on LF and HF values for the past week
The two line graphs shown in FIG. 1 are displayed.

Sixth press (seventh screen) Based on the values of RR50 for the past week, a line graph in the same format as in FIG. 10 is displayed. Note that “LF / H
“RR50” is displayed instead of “F”. 7th press (8th screen) Based on the pulse rate values for the past week, a line graph in the same format as in FIG. 10 is displayed. Note that “LF / H
“Pulse rate” is displayed instead of “F”.

Eighth press (9th screen) The first bar graph shown in FIG. 6 is displayed again. Thereafter, when the display switching button 26 is pressed, the same graph is displayed every eight screens. Thereafter, when the user presses the mode switching button 25 again, the mode is switched to the normal use mode. Then, the CPU 1 instructs the display control circuit 10 to delete the graphic display unit 23, then obtains the date and the day of the week again, and causes the graphic display unit 23 to display them. When the mode switching button 25 is pressed in the analysis mode, the above-described graph display is interrupted, the mode is shifted to the normal use mode, and the date,
The day of the week is displayed.

As described above, according to the present embodiment, the health condition analyzer is incorporated in a wristwatch worn everyday, so that the subject can easily check the health condition at any time. Therefore, the subject can check the condition regularly or irregularly and, if the condition is changed, acquire a habit of consulting with a specialized organization such as a doctor, so that efficient health management can be performed. .

§2. Second Embodiment [Outline of Embodiment] The health condition analyzing apparatus according to the present embodiment includes:
The analysis is performed by using a finger plethysmogram instead of the pulse wave of the radial artery of the subject. Finger plethysmogram is a blood flow pulse wave in the peripheral circulatory system that can be measured non-invasively, and is used as a method to evaluate the state of peripheral circulation, blood oxygen concentration, and physical fatigue and tension. .

In the peripheral circulatory system, at the end of the arterial system, the arterioles branch off into a network of capillaries and then reassemble to form venules, and the total cross-sectional area of the capillaries is extremely large.
Since the collapse state of the true capillaries in this part occurs due to the excitement of the autonomic nervous system, a low-temperature environment, and the like, it is considered that in vivo information can be obtained by measuring the state of this part.

[Structure of Embodiment] The functional parts of the health condition analyzer according to the present embodiment are exactly the same as those of the first embodiment (see FIG. 1). However, as described above, the method of detecting a pulse wave in the present embodiment is different from that in the first embodiment. Thereby, the structure of the wristwatch worn by the user is
This is different from the case of the first embodiment (see FIG. 5).
That is, there is a difference between the first embodiment and the present embodiment in the configuration and structure of the pulse wave detector 4 in FIG.

FIG. 12 shows a mechanical configuration of the health condition analyzing apparatus according to the present embodiment. In FIG.
Reference numeral 20 denotes a main body of the watch, and an LCD (liquid crystal) display unit 12
1, a finger pad 122, a time setting button 123, an analysis mode button 124, and a display switching button 127 are provided. The LCD display unit 121 includes a time display unit 121a and a graphic display unit 121b. This LCD display section 121
Corresponds to the display 9 in FIG.

The current time is displayed on the time display section 121a in both the normal use mode and the analysis mode. That is, the time display is continued even in the analysis mode, so that the user can know the current time during the analysis. On the other hand, the graphic display unit 121b displays information on the date and the day of the week in the normal use mode, and displays messages and information for measurement and analysis in the analysis mode. In addition, the user presses the fingertip of the second finger (for example) of the hand on the side not wearing the wristwatch against the finger rest 122. The time setting button 123 is a button used for setting the time of the wristwatch and other settings, and the analysis mode button 124 is a button used for setting the start / end of the pulse wave analysis function. The display switching button 127 is
Plays the same role as the display switching button 26 in the first embodiment, and switches the display content on the graphic display unit 121b in the analysis mode.

FIG. 13 shows a more detailed configuration of the pulse wave detector 4 incorporated in a wristwatch. In this figure, the optical pulse wave sensor 1 is
25 and a strain gauge 126 are provided. The optical pulse wave sensor 125 includes an infrared (wavelength: 940 nm) light emitting diode 135 and an optical sensor (phototransistor).
136. Infrared light emitting diode 13
The light radiated from 5 is reflected via the blood vessel at the fingertip placed on the finger rest 122, received by the optical sensor 136, and subjected to photoelectric conversion. As a result, a pulse wave detection signal M is obtained. The pulse wave detection signal M is converted into a digital signal by the A / D converter 5 shown in FIG.

Further, since the resistance value of the strain gauge 126 changes according to the strain, a pressure signal P corresponding to the pressing force of the user's finger pressed through the finger pad 122 is detected.
The A / D converter 133 converts the pressure signal P into a digital signal. This digital signal is directly read by the CPU 1 of FIG. Further, in the present embodiment, the pressing force to be applied to the finger pad 122 is <67, 83, 1 in advance.
00, 117, 133> g / cm ² . In the following description, the pressing force is 83 g /
cm ² is set. Furthermore, since the adjustment of the pressing force relies on the pressing force of the user's finger,
Unless a corresponding tolerance is provided for each pressing force, measurement becomes difficult. Therefore, for each of the above pressing forces, “± 2
g / cm ² ".

The CPU 1 described above provides message data for guiding the user to the analysis procedure, and graphic data for guiding the user to press the finger pad 122 with an appropriate pressing force. Figure 1
To the display control circuit 10. The display control circuit 10
Display data is created from these pieces of display information and output to the graphic display unit 121b.

By the way, in order to reduce the power consumption of the battery-type wristwatch as in the present embodiment, the power supplies of the optical pulse wave sensor 125 and the strain gauge 126 are driven only when the analysis mode is executed. Is desirable. Therefore, on the line that supplies power to each of these sensors,
A switch is provided. The symbol S in FIG.
This is a switch provided for the optical pulse wave sensor 125. A similar switch (not shown) is provided for the strain gauge 126. Then, a switch drive circuit (not shown) switches the ON / OFF state of each switch to supply power intermittently to sensors and the like.

That is, while the wristwatch is operating only as a normal wristwatch, the above switches are turned off, and power is not supplied to the optical pulse wave sensor 125 and the strain gauge 126. On the other hand, when the user enters the analysis mode by pressing the analysis mode button 124, each switch is turned on, and the optical pulse wave sensor 125
The power is supplied to the strain gauge 126. Then, when the user presses the analysis mode button 124 again to end the analysis mode, each switch is turned off, and power is not supplied to each sensor.

When viewed from the entire time when the user wears the wristwatch, the time in the analysis mode is considered to be extremely short. Therefore, by supplying power to each sensor used in the analysis mode as described above, current is supplied to each sensor only during the execution of the analysis mode, and the power consumption as viewed from the entire wristwatch is considerably reduced. It is possible to do. In addition, also about the strain gauge 126,
A similar configuration is possible.

[Operation of Embodiment] Next, the operation of the health condition analyzing apparatus having the above configuration will be described. In order to measure the pulse wave at a predetermined time every day, the CPU 1 causes the clock circuit 7 to generate an interrupt signal at, for example, “every two hours from 8:00 am to 10:00 pm” when the power is turned on. To Here, in the present embodiment, since the pulse wave is measured by the user pressing the finger, the night time zone is not set as the measurement time.

(1) Measurement and Analysis of Pulse Wave In order to execute the measurement of the pulse wave at a predetermined time interval (for example, 2 hours), the CPU 1 starts, for example, “2 hours from 00:00 The clock circuit 7 is instructed to generate an interrupt signal at “place”. A. For example, when the clock circuit 7 generates an interrupt signal to the CPU 1 at 2 pm, the CPU 1 executes the pulse wave capturing process for a predetermined time (for example, 30 minutes) in the same manner as in the first embodiment.
Seconds). This capture processing will be described in detail below.

First, the CPU 1 generates an alarm sound by an existing method to notify the user that the pulse wave measurement time has come. At this time, an instruction is given to the display control circuit 10 to display a message such as "Myakuhakarimas"(; measure a pulse) on the graphic display unit 121b. When the user sees this and presses the analysis mode button 124, the wristwatch can be used as a health condition analyzer. When the analysis mode button 124 is pressed again, the wristwatch returns to a normal operation. further,
If the analysis mode button 124 is pressed again during the analysis, the analysis operation is interrupted and the operation returns to the normal operation.

Next, when the operating unit 8 shown in FIG. 1 notifies that the analysis mode button 124 has been pressed, the CPU 1 causes the graphic display unit 121b to display "2 Made Ooatsu" (press to 2).
Is displayed. When the user sees this and places his / her finger on the finger pad 122, the resistance value of the strain gauge 126 changes, and the pressure signal P changes. The CPU 1 detects this pressure change from the output of the A / D converter 133 and switches the graphic display unit 121b to a graph display as shown in FIG. Here, the inverted triangular marks m1 to m5 in FIG.
7,. . . , 133> g / cm ² .

Then, when the user increases the pressing force of the finger and gradually presses the finger, the CPU 1 determines the magnitude of the actual pressing force detected by the strain gauge 126 based on the read pressure signal P. Are displayed in order from left to right, as indicated by the symbol PM (see FIG. 14). The user touches the second finger with the finger contact unit 122 so that the mark PM is displayed up to the position of the mark m2 indicating the second measurement point while referring to the bar-shaped mark (the state of FIG. 14B). Press

In a state where the mark PM is displayed up to the position of the mark m2, it indicates that the current pressing force is within the measurement allowable range (83 ± 2 g / cm ² ) of the second measurement point. Further, when the pressing force slightly deviates from the measurement allowable range, the mark PM before and after the mark PM blinks in and out. When it is detected that the pressing force is within the measurement allowable range for a short period of time, the CPU 1 terminates the graph display on the graphic display unit 121b, and replaces it with a message of "Sonoramasei"(; still as it is). Is displayed.

If the user moves his or her finger during this short period and the pressing force is out of the above-mentioned allowable range, the graphic display section 121b displays "Yarina Oshikudasai"(; start over). Message is displayed. Thereafter, the display of the graphic display section 121b is switched again to the above-mentioned graph display, so that the user again operates the mark P.
The pressing force is adjusted so that M is displayed up to the position of the mark m2.

When the pressing force becomes substantially constant in this way, measurement of a pulse wave is subsequently performed. The measuring operation of the pulse wave is the same as that of the first embodiment. The CPU 1 sets a predetermined time (for example, 30 seconds) in the clock circuit 7 and the A / D converter 5 only measures the pulse wave during this period. Signal to data memory 6
Take in.

B. Analysis of Pulse Waveform Next, the CPU 1 analyzes the waveform of the pulse wave and calculates the RR interval, as in the analysis processing of the first embodiment. Then, RR
By performing spectral analysis by interpolating the interval, L
F, HF, “LF / HF”, RR50, and pulse rate are sequentially calculated and stored in the data memory 6 together with the measurement time. As described above, the state of the living body is periodically measured.

(2) Display of Measurement Result When the user presses the analysis mode button 124 in order to know the current state of health, the CPU 1 clears the graphic display section 121b as in the first embodiment. Here, since the time of pressing this button does not correspond to the time of the periodic measurement of the pulse wave,
PU1 can recognize that the pressing of this button is due to the user's will. A. Collection of the current value of the state of the living body

Next, the CPU 1 executes the above-mentioned "(1) Measurement and analysis of pulse wave" process. That is, for 30 seconds,
The fingertip pulse wave is fetched into the data memory 6 and the current LF, HF, "LF / HF", and RR50 are analyzed from the pulse wave waveform analysis.
Is calculated. B. Interpolation Process Next, as in the first embodiment, the CPU 1 calculates the current state of the living body by interpolating the values of the past state of the living body. In addition, a moving average is obtained for each living body state. C. Graph Display In exactly the same procedure as in the first embodiment, the graph of the state of the living body shown in FIGS. 6 to 11 is displayed on the graphic display unit 121b when the user presses the display switching button 127.

In this embodiment, a strain gauge is employed as the pressing force detecting means. However, the present invention is not limited to this. The finger contact portion may be a movable mechanism using a spring, and the pressing force may be determined based on the degree of expansion and contraction of the spring. It may be detected. Although the wristwatch is presented as a portable form of the health analysis device, the present invention is not limited to this, and the same device can be incorporated in other everyday items.
Further, the part for detecting the pulse wave is not limited to the fingertip of the finger, and the toe or the other end may be similarly pressed and measured. Also, the graph display shown in FIGS. 6 to 11 may be performed at the time of the periodic measurement of the pulse wave.

§3. Third Embodiment In the present embodiment, a description will be given of a case where the health condition analyzing apparatus is combined with an accessory (accessory). here,
The necklace shown in FIG. 15 is taken as an example of the accessory, but there is no problem even with other accessories. In this figure, reference numeral 131 denotes a sensor pad, which is made of, for example, a sponge-like cushioning material. In the sensor pad 131, a photoelectric pulse wave sensor 125 corresponding to the pulse wave detector 4 in FIG. 1 is attached so as to come into contact with the skin surface. Thus, when the necklace is put on the neck, the photoelectric pulse wave sensor 125 can contact the skin on the back side of the neck to measure the pulse wave. The above-described photoelectric pulse wave sensor 125 is exactly the same as that shown in FIG.

The main body 137 having a hollow portion incorporates the components (such as the CPU 1) shown in FIG. 1 except for the pulse wave detector 4. The main body 137 has a broach-like shape, and is provided with a graphic display section 23, a mode switching button 25, and a display switching button 26 similar to those shown in FIG. The photoelectric pulse wave sensor 125 and the main body 1
37 are attached to the chains 134, respectively, and are electrically connected via lead wires (not shown) embedded in the chains 134. In this embodiment, since the clock function itself is unnecessary, the main body 137 is not provided with the time display section 22 and the time setting button 24 shown in FIG.

In this embodiment, the pulse wave is generated by the pressure sensor 2 shown in FIG.
7, not by the photoelectric pulse wave sensor 125,
The only difference is that a pulse wave at the neck is measured instead of a pulse wave at the radial artery. That is, the health condition analyzer according to the present embodiment is the same as the first embodiment except that the pulse wave is captured as described in the second embodiment, and the state of the living body is automatically collected every predetermined time. The analysis result is displayed according to the user's instruction. Therefore, a detailed description of the operation of the health condition analyzing apparatus according to the present embodiment will be omitted.

§4. Fourth Embodiment In this embodiment, a case will be described in which the health condition analyzing apparatus is combined with eyeglasses. FIG. 16 is a perspective view illustrating a state where the health condition analyzing apparatus is attached to eyeglasses. As shown in this figure, the health condition analyzer is attached to a vine 151 of a frame of glasses. The main body of this health condition analyzing apparatus is divided into a main body 152a and a main body 152b, and each is separately attached to the vine 151. Further, these main bodies are electrically connected to each other via lead wires embedded inside the vine 151. Note that this lead wire may be crawled along the vine 151.

The main body 152a corresponds to the display control circuit 10 in FIG. A liquid crystal panel 153 is attached to the entire surface of the main body 152a on the side surface on the lens 150 side. A mirror 154 is fixed to one end of the side surface at a predetermined angle. Further, a drive circuit for the liquid crystal panel 153 including a light source (not shown) and a circuit for creating display data are incorporated in the main body 152b. Light emitted from this light source is reflected by a mirror 154 via a liquid crystal panel 153, and is projected on a lens 150 of spectacles. The mirror 154
May be movable so that the user can adjust the angle between the liquid crystal panel 153 and the mirror 154.

The main body 152b has a pulse wave detector 4,
Each part (CPU 1 etc.) of FIG. 1 except for the display 9 and the display control circuit 10 is incorporated, and the mode switching button 25 and the display switching button 2 same as FIG.
6 are provided. In addition, as in the third embodiment,
The mode switching button 25 and the display switching button 26
The time display section 22 and the time setting button 24 shown in FIG.

The structure of the pulse wave detector 4 (see FIG. 1) is the same as that of the third embodiment, and is an optical pulse wave sensor 125 shown in FIG. Here, the infrared light emitting diode 1
35 and the optical sensor 136 are built in the pads 155 and 156 shown in FIG.
Further, the earlobe is sandwiched by the pads 156 so as to be fixed to the ear. These pads 155 and 156 are electrically connected by lead wires 157, 157 drawn from the main body 152b, as shown in FIG. In the present embodiment, since the various graphs described above are configured to be projected on the lens 150 of the glasses, it can be said that the lens 150 of the glasses corresponds to the display 9 in FIG.

The difference between this embodiment and the first embodiment is that
Since the pulse wave is captured by the photoelectric pulse wave sensor 125 of FIG. 13 instead of the pressure sensor 27 of FIG. 5, the pulse wave of the earlobe is measured instead of the pulse wave of the radial artery, and FIG.
Only the graph shown in FIG. 11 is displayed on the lens 150. Therefore, the operation of the health condition analyzing apparatus according to the present embodiment is the same as that of the above-described embodiment, and the description thereof is omitted here. In this embodiment, the case where the main body is divided into the main body 152a and the main body 152b has been described, but there is no problem if they are integrally configured.

In the above embodiment, from the viewpoint of directly appealing to the visual sense, the analysis result of the health condition is displayed as a graph. However, the present invention is not limited to this. For example, a numerical display may be used. In addition, for example, the maximum value and the minimum value of RR50, LF, etc. in the past week are respectively detected, and when the current value is larger or smaller than those values, a warning is sounded by a buzzer or the like, and the display of abnormality is performed. It may be performed. In addition, there is a difference between values of RR50 and the like between day and night. Therefore, the maximum value / minimum value in the daytime zone and the maximum value / minimum value in the nighttime zone are separately obtained, and each time zone is determined according to whether the present time is the daytime zone or the nighttime zone. May be compared with the current value.

The values such as RR50 change depending on the intensity of the movement of the user. Then, you may comprise as follows. That is, the acceleration sensor is attached to a part of the body of the user, and the value of the acceleration sensor is measured simultaneously with the measurement of the pulse wave. Then, the value such as RR50 and the value of the acceleration sensor are stored in the memory in pairs. When the user wants to know the current health condition, the user presses the mode switching button 25. When the mode switching button is pressed, the pulse wave is measured and the output of the acceleration sensor is detected. Next, the value of the acceleration sensor in the memory closest to the current output value of the acceleration sensor is detected, and a value such as RR50 paired with the detected value of the acceleration sensor is read out from the memory, and is read together with the current value. Is displayed.

In the above embodiment, after the mode switching button 25 is pressed, the pulse wave is measured to calculate the "current" state of the living body. As an alternative to this, the pulse wave waveform is always loaded into the data memory 6,
A method of always storing a waveform for a predetermined time (for example, 30 seconds) in the data memory 6 is conceivable. Then, when the mode switching button 25 is pressed, the state of the living body is calculated from the accumulated pulse wave waveform without measuring the pulse wave again. This makes it possible to significantly reduce the time from when the user presses the button until the result is displayed.

[0086] Further, when a subject finds an abnormality, R is determined so that a doctor or the like can make a diagnosis from various viewpoints.
The result of the spectrum analysis at the R interval may be displayed in a graph. Further, when the user presses the display switching button 26, the information to be displayed on the graphic display unit 23 is switched. However, by automating this,
You may make it display in order every predetermined time (for example, 5 seconds). In this way, it is possible to eliminate the trouble of operating the button each time another information is viewed.

Also, wristwatches, necklaces, and glasses have been presented as portable health analyzers.
However, the present invention is not limited to this, and it may be incorporated in other everyday items. Further, the part for detecting the pulse wave is not limited to the radial artery and the neck, and the measurement may be performed at another part as long as the pulse wave characteristics similar to those in the above embodiment can be obtained. Further, the method of detecting the pulse wave is not limited to the method described in the above embodiment, and various other methods such as an optical method, a method using sound, electromagnetic waves, and the like can be considered.

The optical pulse wave sensor used in the second to fourth embodiments can be applied to the first embodiment. That is, the optical pulse wave sensor 12 shown in FIG.
5 is incorporated in the wristwatch 20 shown in FIG. 5 as the pulse wave detector 4 shown in FIG. Then, a window is provided on the back surface of the wristwatch 20, and the infrared light emitting diode 135 and the optical sensor 136 in FIG. With this configuration, the infrared light emitting diode 135
Is emitted to the skin in contact with the back surface of the wristwatch 20 (the plastic plate attached to the wristwatch), reflected by blood vessels passing directly under the skin, and received by the optical sensor 136. This light is photoelectrically converted by the optical sensor 136, and the pulse wave detection signal M obtained as a result is sent to the A / D converter 5 in FIG. 1 to be used for pulse wave measurement.

The following modification can be considered by using the optical pulse wave sensor 125 described above.
In the first embodiment, the pulse wave is measured at the base of the finger instead of measuring the pulse wave at the radial artery. That is, the pulse wave detector 4 in FIG. 1 is configured as shown in FIG. 17 (in place of the pressure sensor 27 in FIG. 5). In FIG. 17, for example, a band 141 is wound around the base of the second finger. The band 141 is provided with an optical pulse wave sensor 125 (not shown) in FIG. 13, and a pulse wave at the base of the finger is obtained as a pulse wave detection signal M at an output terminal of the sensor. The band 141 and the wristwatch 20 are connected to the lead 1
The pulse wave detection signal M thus obtained is electrically connected to the A / D converter 5 shown in FIG. In this way, the pulse wave is measured in the same manner as described above.
