Abstract

PROBLEM TO BE SOLVED: To enable measurement of a blood pressure and a body fat rate simultaneously by arranging an electrocadiographic measurement part and a body fat measuring part electrically insulated therebetween to let a measuring person hold first and second handles. SOLUTION: An electrocadiographic electrode 2A, a pulse sensor 2B and a body fat electrode 2C are mounted on a first grip held by one hand and an electrocadiographic electrode 3A and a body fat electrode 3C are mounted on a second grip held by the other hand. After the first and second grips are held by both the hands, an electrocadiographic value is measured by the eleetrocardiographic electrodes 2A and 3A and a pulse is measured by the pulse sensor 2B. Then, a blood pressure value is determined from a time difference between the electrocardiographic value and the pulse. At this point, a body fat rate is determined from a specific resistance of a human body to be measured by the body fat electrodes 2C and 3C and the blood pressure value and the body fat rate thus obtained are shown on a display part 8. This enables measuring of the blood pressure value and the body fat rate with one measurement.

2. Description of the Related Art Both the measurement of blood pressure and the measurement of body fat percentage are indispensable for the prevention of adult diseases. Conventionally, blood pressure is measured by a sphygmomanometer and body fat percentage is measured by a body fat meter. As a conventional sphygmomanometer, a sphygmomanometer that measures a blood pressure by wrapping a cuff around an upper arm or a wrist, pressurizing the cuff and measuring a counter pressure thereof is commercially available. However, there is an annoyance due to the attachment of the cuff and an uncomfortable feeling due to the pressure. The wrist-worn wristwatch incorporates an optical pulse sensor and an electrocardiographic electrode, measures the pulse and heart rate with the optical pulse sensor, and since the pulse propagation time is proportional to the blood pressure, (Japanese Patent Laid-Open No. 7-1)
No. 16132).

On the other hand, a conventional body fat meter that grasps two handles with both hands, applies a weak current to the body from electrodes provided on each handle, and calculates the body fat percentage from the specific resistance of the body is commercially available. Have been.

Both the measurement of blood pressure and the measurement of body fat percentage are indispensable for the prevention of adult diseases. However, as described above, conventionally, blood pressure and body fat are separated by separate devices (a sphygmomanometer and a sphygmomanometer). It is necessary to measure separately with a body fat meter.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a health management device capable of measuring blood pressure and body fat percentage by a single measurement.

[0006]

A measurer holds first and second handles. In this state, the electrocardiogram is measured from the hand held by the electrocardiographic electrode, and the pulse is measured by the pulse sensor. The blood pressure measurement unit calculates the blood pressure from the time difference between the measured electrocardiogram and the measured pulse. In addition, while the measurer holds the first and second handles, the specific resistance is measured from the hand held by the body fat electrode. The body fat measurement unit calculates a body fat percentage from the measured specific resistance. Here, the electrocardiogram measurement unit and the body fat measurement unit are electrically insulated, and the measurer can measure the blood pressure and the body fat percentage at once by holding the first and second handles.

Embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic block diagram of a health management device, FIG. 2 is a perspective view of the health management device, and FIG. 3 is a diagram showing the arrangement of electrodes and sensors provided on left and right handles.

As shown in FIG. 2, the health management device comprises a main body 1 and first and second grips 2 and 3 respectively held by left and right hands LH and RH. As shown in FIG.
As shown in the figure, the electrocardiographic electrode 2A, the optical pulse sensor 2
B, the body fat electrode 2C is attached, and the second handle 3
, An electrocardiographic electrode 3A and a body fat electrode 3C are attached.

When the first and second grips 2 and 3 on the left and right are grasped by hands, the index finger naturally contacts the electrocardiographic electrodes 2A and 3A, the middle finger naturally contacts the pulse sensor 2B, and the ring finger naturally contacts the body fat electrodes 2C and 3C. The ECG electrodes 2A, 3A, the pulse sensor 2B and the body fat electrodes 2C, 3C are arranged at regular intervals so as to be placed, and the first and second handles 2,
The handle 3 is provided in a concave shape in an arc shape. Here, each of the index finger, the middle finger, and the ring finger does not need to correspond to each electrode or sensor as described above.

The main body 1 has an electrocardiogram measuring section 4 for measuring electrocardiograms from signals obtained by the electrocardiographic electrodes 2A, 3A.
A pulse measurement unit 5 that measures a pulse from a signal obtained by the pulse sensor 2B, and a blood pressure measurement unit that calculates a blood pressure from a time difference between the electrocardiogram measured by the electrocardiogram measurement unit 4 and the pulse measured by the pulse measurement unit 5 6. A body fat measurement unit 7 for calculating a body fat percentage from the specific resistance measured by the body fat electrodes 2C and 3C is provided. In addition, the main body 1 is provided with a display unit 8 that displays the blood pressure value calculated by the blood pressure measurement unit 6 and the body fat percentage calculated by the body fat measurement unit 7.

When the measurer grasps the first and second grips 2 and 3 with both hands, the body of the measurer becomes a conductor, a weak current flows through the left and right body fat electrodes 2C and 3C, and the body resistance is determined from the specific resistance. The measuring unit 7 obtains the body fat percentage.

At the same time, the left and right electrocardiographic electrodes 2A and 3A also conduct, and the electrocardiogram measuring section 4 measures electrocardiographic signals. Here, when the body fat and the electrocardiogram are measured by the same circuit, the electrocardiographic electrodes 2A, 3
A and the body fat electrodes 2C, 3C are electrically connected, and the electrocardiographic signal cannot be measured. Therefore, the electrocardiograph 4
An electric filter is inserted in the preceding stage so that only an electrocardiographic signal is input to the electrocardiographic measuring unit 4. Also, in order to measure body fat and electrocardiogram in the same circuit, utilizing the fact that electrocardiographic signals are repeatedly generated at intervals of 0.4 to 1.2 seconds, within the interval where there is no strong electrocardiographic signal, A relay circuit may be incorporated in the body fat measurement unit 7 so as to measure body fat. On the other hand, a light emitting element and a light receiving element are incorporated in the optical pulse sensor 2B, and light emitted from the light emitting element is reflected by a fingertip and detected by the light receiving element. Since a part of the emitted light is absorbed by the blood and the amount of light reflection changes, the light receiving signal of the light receiving element is sent to the pulse measuring unit 5 and processed as a pulse signal.

The electrocardiographic signal and the pulse signal obtained by the electrocardiographic measuring section 4 and the pulse measuring section 5 are sent to a blood pressure measuring section 6. The blood pressure measurement unit 6 calculates a time difference between the electrocardiogram and the pulse. Since the calculated time difference is statistically correlated with the blood pressure value, the blood pressure measurement unit 6 obtains the blood pressure value using a predetermined conversion formula.

The body fat percentage obtained by the body fat measuring section 7 and the blood pressure value obtained by the blood pressure measuring section 6 are displayed on the display section 8 of the main body 1. In this way, the measurer calculates the body fat percentage and the blood pressure value, which have been measured separately until now,
By using the health care device according to the present invention, measurement can be performed with a single measurement, which can be used for preventive health care of lifestyle-related diseases.
