Next, a method of measuring the impedance of each part of the body by the health management device 1 of this embodiment will be described with reference to FIG. As shown in the figure, the electrodes E1 to E8 are brought into contact with predetermined parts of the limbs of the subject to measure the impedance of each part of the body.

In FIG. 4, symbols P1 to P6 are virtual measurement points used in the impedance measurement method known per se, and when measuring the impedance of each part of the body, a current described later is used. It is a measurement point for detecting a voltage that is virtually located at a position closest to the voltage measuring electrode on the road. This virtual measurement point is an intersection of the voltage detection line and the current path, which is the shortest path from the voltage measurement electrode to the current path when the voltage on the current path is detected by the voltage measurement electrode not located on the current path. Then, since there is no current conduction along the voltage detection line and almost no potential drop occurs, it is possible to measure the voltage at the virtual measurement point by the voltage measurement electrode arranged apart from the current path. .

When a current is supplied to the human body by the current path forming electrodes E1 and E5, a current path that passes through the left arm part, the body part, and the left leg part in the body of the subject, with the index finger and the left foot of the left hand as the ends.

In this way, by measuring the potential difference detected by the electrodes E2 and E3 which are electrodes for voltage measurement, the impedance Z1 of the left arm portion between the virtual measurement points P1 and P3 can be measured. Further, by measuring the potential difference detected by the electrodes E3 and E7 which are electrodes for voltage measurement, the impedance Z3 of the body portion between the virtual measurement points P3 and P4 can be measured. Furthermore, by measuring the potential difference detected by the electrodes E6 and E7, which are electrodes for voltage measurement, the impedance Z4 of the left leg between the virtual measurement points P4 and P5 can be measured.

Next, by switching the electrode changeover switch 11, a current is supplied to the human body by the current path forming electrodes E4, E8, and the index finger and the right foot of the right hand are the ends in the body of the subject, and the right arm portion. A current path is formed that passes through the body and the right leg. In this way, by measuring the potential difference detected by the electrodes E2 and E3 which are electrodes for voltage measurement, the impedance Z2 of the right arm portion between the virtual measurement points P2 and P3 can be measured. Further, by measuring the potential difference detected by the electrodes E2 and E6 which are electrodes for voltage measurement, the impedance Z3 ′ (not shown) of the body portion between the virtual measurement points P3 and P4 can be measured. Furthermore, when the potential difference detected by the electrodes E6 and E7, which are electrodes for voltage measurement, is measured, virtual measurement points P4 and P
The impedance Z5 of the right leg between 6 can be measured.

As described above, according to the impedance measuring method according to the present embodiment, the impedances of the left and right arm portions, the body portion, and the left and right leg portions are directly calculated from the measurement without any calculation based on the measured impedance. You can ask. Regarding the impedance of the body,

It is used to enable more effective health management.

The display screen of this progress graph displays the numerical values and levels of the weight, body fat percentage, visceral fat area index and body muscle levels of the whole body, arms and legs, which are the health indexes of the subject. It consists of a graph display. 12
In (a), a progress graph display screen for weight values is illustrated. On this screen, the current measurement value and the past measurement value (level value for body muscle level) are displayed in the upper part and the middle part of the liquid crystal screen together with the display of the past measurement period. Here, the past measurement period is 1 to 12 weeks ago (weekly), 4 months to 6 months ago (1
It is possible to select from three types of periods: monthly) and 6 months to 24 months (3 months). The display of the measurement period displays the final value of the week in week units and the final value of 30 days in the month in monthly units.

On the other hand, the progress graph is displayed as a bar graph by dot display in the lower part of the liquid crystal screen. In this bar graph display, the horizontal axis is the time axis, the right end of the time axis is the current value, and the bar graph is displayed in minimum units for each measurement period. Here, the horizontal axis (time axis) can be, for example, 8 scales. Further, the vertical axis (numerical axis) is represented by 0.1 kg unit, 0.1% unit, and 5 cm ² for body weight, body fat percentage, and visceral fat area index, and body muscle level is represented by a judgment level. And can be displayed with, for example, 7 dots. The body muscle determination level is a value obtained by estimating the muscle mass (kg) of the whole body, legs, and arms of an unspecified large number of groups according to sex and age, divided by the body weight of the subject. Muscle rate (%)
As a result, a histogram is created with the abscissa as the body muscle rate and the ordinate as the frequency, and the standard within the range of ± 1σ of the average is −1.
This is a criterion for determining that σ is less than or equal to less and more than +1 is greater. The level determination display is a bar graph with a small range of 2 dots, a standard range of 4 dots, and a large range of 2 dots.

On the display screen of the progress graph, one of the past bar graphs and the numerical value indicating the time unit of this bar graph are simultaneously displayed in blinking, and they are moved in the time axis direction by the ten keys 6h used as left and right keys. At this time, the past measurement value in the middle part of the display screen or the judgment level display is also switched to that in the measurement period of the blinking display part. When the blinking exceeds the left end of the time axis, the graph display of the next span is switched.

Further, in the case where the results of a specific period in the past measurement period are not obtained in the progress graph display of the body weight, the body fat percentage, and the visceral fat area index, FIG.
As shown in (b), only the dot at the tip of the bar graph is turned on based on the value estimated from the measured values before and after the display at this specific time.

When the memory key 6d is turned ON on the progress graph display screen, the target value display screen as shown in FIG. 13 can be displayed. This target value display screen numerically displays the target weight value or the target body fat percentage with respect to the input values for the weight and the body fat percentage. Regarding this target value display, regarding the weight and body fat percentage of the subject, in order to bring either one of these weight and body fat percentage close to the target value, it is necessary to calculate and display how much the other should be. Thus, the subject is informed of the other target value and is used as a guideline for effective implementation of diet and exercise therapy for achieving the target. Therefore,
In the health management device 1 of the present embodiment, when the numerical value of one of the weight and the body fat percentage is arbitrarily changed from the current measurement result of the subject, the estimation result of the other is displayed. ing.

The method of calculating the target value will be described based on the equation (1). The present measured values of body weight and body fat percentage of the subject are W ₁ , BMI ₁ and FAT, respectively.
