[0015]
FIG. 1 is a basic system block diagram of the present invention, FIG. 4 is a basic component configuration diagram of the present invention, and FIG. 5 is a diagram showing a wearing state of an ear-mounted pulse meter according to the present invention. .
[0016]
A pulse sensor 500 for detecting a pulse is attached to the earlobe as shown in FIG. 5 and exposes a light emitting element 13 such as a light emitting diode and a light receiving element 14 such as a phototransistor in the earlobe clip 12 as shown in FIG. 1, the change in the current of the light receiving element 14 is converted into a voltage by the amplification filter unit 501 in FIG. 1, and amplified and filtered to detect a value corresponding to the change in blood flow in the earlobe as a change in voltage. To do.
[0017]
The output of the amplification filter unit 501 is an electrical signal corresponding to a pulse, and is connected to the multicolor light emitting element driving unit 504, and blinks the multicolor light emitting element 15 in accordance with a change in blood flow in the earlobe portion, that is, a pulse state.
[0018]
The output of the amplification filter unit 501 is connected to the FV converter 502, the pulse rate is converted into a voltage value, the output is connected to the voltage comparator 503, and multicolor light emission is performed according to the set voltage value. A control signal is sent to the multicolor light emitting element driving unit 504 so as to select a color to be emitted by the element.
[0019]
For example, if the multicolor light emitting element 15 is a three-color LED that emits three colors of green, orange, and red, the red light is emitted when only the red LED in the light emitting element is energized, and the green light is emitted when the green LED is energized. The red LED and the green LED are configured to emit orange when energized.
[0020]
As shown in the time chart of FIG. 2 and the diagram showing the relationship of the output to the pulse rate in FIG. 3, for example, if the pulse rate is less than 100 (beats / minute), the color of the three-color LED emits green. To do. As shown in FIG. 3, if the output voltage of the FV converter 502 at 100 (beats / minute) is Vb, the output voltage of the FV converter 502 is set in the voltage comparator 503 of FIG. When the voltage is equal to or lower than the voltage Vb, the voltage comparator 503 sends a control signal to the multicolor light emitting element driving unit 504 so as to emit the color of the three-color LED in green.
[0021]
Similarly, if the pulse rate is 100 (beats / minute) or more and less than 140 (beats / minute), both the red LED and the green LED of the three-color LED are energized to emit orange light, and the pulse rate is If it is 140 (beats / minute) or more, the three-color LED emits red light, and the three-color LED blinks according to the pulse rate. Of course, the reference voltage of the voltage comparator may be changed according to the age of the user.
[0022]
As shown in the figure showing the wearing state of FIG. 5, the multicolor light emitting element 15 of the earlobe clip 12 attached to the earlobe part blinks at the same tempo as the pulse state of the person wearing it, and as the pulse rate becomes faster Since the blinking color changes, it becomes possible to know the beating state of the person wearing it from the color and the speed of blinking.
[0023]
Next, the output of the amplification filter unit 501 in FIG. 1 is connected to the modulation unit A506, and modulates the sound of the first sound source A505 according to the blood flow volume of the earlobe part, that is, the pulse state, and has the same tempo as the heartbeat. Then, the speaker 4 is sounded through the speaker driving unit 507. As shown in FIG. 4, the output sound of the speaker 4 passes through the sound guide tube 6 and the sound path 7 in the hook 2 and reaches the vicinity of the ear hole as shown in the diagram showing the wearing state of FIG. The person who wears can hear the tempo of his / her pulse state with his / her ears.
[0024]
Further, in the voltage comparator 503, for example, if the pulse rate is less than 30 (beats / minute) or 140 (beats / minute) or more, the switch circuit in the modulation unit B508 is turned on to turn on the second sound source B507. The speaker 4 is caused to ring through the speaker driving unit 507, and an alarm sound is output to the wearer. Here, 140 (beats / minute) or more is the same as the determination value for switching the color of the multicolor light emitting element 15 to red, but this determination value may be different from the determination value for switching the color of the multicolor light emitting element 15 to red. good. In addition, the sound of the second sound source B507 may be a sound such as “Solid” or “Is it all right?”, Or may be useful for awakening when the consciousness is fading.
[0025]
The mode selector switch 9 shown in FIG. 1 or FIG. 4 is a switch for switching on / off the power source of the electronic circuit and ON / OFF state of the blinking of the multicolor light emitting element 15, and the volume volume 8 is a speaker. 4 is a volume for adjusting the output volume. However, when outputting the sound of the second sound source B 507, the speaker 4 may be sounded without using the volume volume 8.
[0026]
FIG. 4 is a basic component configuration diagram of the present invention. The case 1, the hook 2, the battery 3, the speaker 4, the sound guide tube 6, the sound path 7, the volume volume 8, and the mode selector switch 9 are the conventional ones. The electronic circuit board 5 in the case 1 is changed from the conventional electronic circuit board for a hearing aid to the electronic circuit board 5 shown in FIG. 1 or FIG. The connector 10 is provided in the portion where the electronic device is mounted, and the light emitting device 13, the light receiving device 14, the multicolor light emitting device 15, and the microphone 16 installed in the external earlobe clip 12 are connected via the cable 11 to the electronic circuit.

The case 1 is used so as to be placed between the back side of the auricle and the head.
[0029]
In the above description, the electronic circuit of FIG. 1 is an analog circuit. However, a digital circuit as shown in FIG. 6 may be used. For example, the output waveform of the amplification filter unit 501 is passed through a pulse shaper 511 that shapes the output waveform into a pulse waveform, and the clock signal output from the clock circuit 513 is used instead of the F-V converter 502 in FIG. A pulse period measuring unit 512 that measures the period of the output pulse is provided, and the pulse pulse period that is the output is provided in place of the voltage comparator 503 in FIG. it can. For example, when it is determined that the pulse rate is less than 30 (beats / minute), the pulse period comparator 514 can determine that the pulse pulse period has exceeded 2 seconds. Here, the pulse pulse period (seconds) can be calculated as a value obtained by dividing 60 by the pulse rate. Further, all functions may be performed based on an execution program using a microprocessor. Alternatively, a plurality of electrodes may be provided on the auricle or earlobe, and body movement may be detected from changes in skin electrical resistance to correct the pulse rate or pulse cycle value.
[0030]
Next, an embodiment of a function for instructing a breathing method for controlling the heart rate when the pulse rate suddenly changes will be described.
[0031]
As shown in the system block diagram of FIG. 7, with respect to the system block diagram of FIG. 6, the signal of the clock circuit 513 is input to the pulse period comparator 514, and the output of the pulse period comparator 514 is input to the sound source B of 507. Change the circuit to do so. As shown in FIG. 8, the block diagram 514 of the pulse period comparator 514 divides the signal of the clock circuit 513 by the counter 601 and sets the divided period as a constant time in the memory 604 every fixed time. The signal of the pulse period measuring device 512 is set, and a difference between the “previous pulse period” set in the memory 604 and the current pulse period output from the pulse period measuring device 512 is calculated by the calculator 605. The difference is set as “change in pulse period” in the buffer of the comparator 3 in 606, and compared with the pulse period (P3) corresponding to the third determination value and the pulse period (P4) corresponding to the fourth determination value, respectively. If the pulse rate is greater than the third judgment value for a certain period of time, the sound source B of 507 can output a voice “hold a breath longer”. If the absolute value of the decrease in the pulse rate is larger than the fourth determination value during the period of time 507, the sound source B of 507 can output the voice “slow breath”, and in each case 508 The switching circuit of the modulation section B is connected so that each sound is output from the speaker 4.
[0032]
The time chart of FIG. 9 shows that when the heart rate suddenly rises, the sound “Breath longer” is output from the sound source B, and when the heart rate suddenly falls, “slow breath slowly”. In this example, the voice “
[0033]
In the above description, an example of outputting by voice has been shown, but it may be output by a melody with different timbres, or by outputting a buzzer sound of the same timbre, and changing the breathing method at the judgment of the user. Also good. In the above description, the example of using the signal of the pulse period measuring device 512 sampled by the counter 601 at regular time intervals as the “previous pulse period” set in the memory 604 has been shown. A moving average value or a filtered value of the signal of the pulse period measuring device 512 may be used.
[0034]
