BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a body fat mass, a body fat percentage, an obesity judgment result, and a judgment based on body specific information (height, weight, age, sex, etc.) of a subject and body impedance measurement information. The present invention relates to a body fat meter that calculates and displays the degree of a result and uses the displayed result to help health management.

[0002]

2. Description of the Related Art In general, a body fat meter for measuring a body fat percentage is equipped with a pair of electrodes at two different points in a living body, and measures the bioimpedance between the two points. In some cases, the body fat percentage is calculated from the data and the obtained body fat percentage is displayed on a display. Also, as general display modes of this type of body fat meter, there are at least three modes: a personal information input mode, a measurement mode, and a measurement result display mode.

[0003]

In the above-mentioned conventional body fat meter, if the body moves during the measurement, the influence appears in the measurement result, and there is a possibility of erroneous measurement. Did not have a function to notify the person. Therefore, when a body motion occurs, there is a problem that an abnormal measurement value is displayed or a measurement error occurs.

[0004] The present invention has been made in view of the above problems, and has as its object to provide a body fat meter capable of notifying a user of the occurrence of body movement.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in more detail with reference to an embodiment. FIG. 1 is a block diagram showing a configuration of a body fat meter according to an embodiment of the present invention. This body fat meter has a display 1 and
A key input unit 2 including a power switch, a mode switch, a measurement start switch, and a 10 key; a buzzer 3; a CPU 4 for executing a series of control processes for measuring body fat; a power source 5 such as a battery; A constant current generating circuit 6 for supplying a constant current to the human body, and electrodes 8 for measurement
And a voltage detection circuit 7 for measuring impedance of a living body
It is composed of The mode switch is a switch for inputting data such as height, weight, age, and gender.

As shown in FIG. 8, the display 1 includes a plurality of display units (in this case, 12 display units) for displaying height, weight, body fat mass, body fat percentage, age, gender, obesity degree (judgment result), and measurement process. ) Bar display. In this display device 1, the judgment result is divided into four stages of “thin”, “standard”, “light obesity”, and “obesity”, and three bars are assigned to each display region of each judgment result. I have. The meaning of the three bars displayed in the display area of each determination result is “low” when only one bar on the left is displayed, “medium” when two bars are displayed, When all three bars are displayed, it indicates "high". The determination result is determined based on information such as height, weight, age, body fat mass, and body fat percentage, and a bar is displayed from left to right to a display area of the determination result. Therefore, according to the display area where the tip of the bar graph exists and the number of bars in this display area,
The determination result and the degree of the determination result can be known.

Next, the overall operation of the body fat meter according to this embodiment will be described with reference to the overall flowchart shown in FIG. When the power switch of the key input unit 2 is turned on, the determination of "whether the power switch is ON" is YES (step (hereinafter abbreviated as ST) 1), and personal data is input from the key input unit 2 (ST2). Here, as the personal data, height, weight, age, and gender are input. These personal data are
Enter all using the mode switch and the 10 keys. FIG. 9 shows an example of a display mode in which personal data is input. When all data is entered, "Do you want to enter all data?"
Is determined to be YES (ST3), and then a determination is made as to whether the measurement start switch is ON (ST4).

When the measurement start switch is turned on, impedance measurement is started every second (ST5). And
When the measurement is started, first, the mode is set to mode 1, and thereafter, the measurement stage proceeds to mode 2 and mode 3 sequentially. This mode change automatically proceeds, and details will be described later. In the measurement, a current is applied to the living body from the constant current generating circuit 6 through the electrodes 8 and 8, the voltage is detected by the voltage detecting circuit 7, and the biological impedance is measured based on the voltage. Is calculated. Most of all, this technique is already well known. When the measurement is completed (ST6), the measurement result, that is, the body fat value (body fat mass, body fat percentage) is displayed on the display 1 (ST7), and after one minute has passed (ST8), the measurement is completed.

Next, the operation of each mode in the measurement process of ST5 will be described with reference to the flowcharts shown in FIGS. First, when the measurement routine is entered, the mode is set to mode 1 and it is determined whether or not the flag every second is ON (ST1).
0) If the flag is OFF every second, the process waits until the flag is turned ON. If the one-second flag is turned on, the one-second flag is turned off (ST11), and then impedance measurement is performed (ST12). Then, the differential impedance (impedance change in one second) is also calculated (ST13). Next, it is determined whether or not the mode is 1 (ST
14). Since the mode is initially mode 1, the determination is YES,
Next, the three bars are blinked on the display 1 (ST1).
5). This display state is shown in FIG. Thereafter, it is determined whether "3 seconds have elapsed since the start of the measurement" (ST16),
Return to ST10 until 3 seconds have elapsed since the start of measurement, and return to ST10.
10 to ST16 are repeated, and the blinking operation of FIG. 10 is continued.

When three seconds have passed, the determination in ST16 is YE
In S, the mode is set to mode 2 (ST17), and after returning to ST10, the process proceeds to the next processing step shown in the flowchart of FIG. Since it is mode 2, ST1
The determination at 8 is YES, and this time, as shown in FIG.
The six bars of the display 1 are blinked (ST19), and it is further determined whether "5 seconds have elapsed since the start of the measurement" (ST2).
0) Until 5 seconds have elapsed, return to ST10 and continue the blinking of FIG. When 5 seconds elapse after the start of measurement, ST2
If the determination of 0 is YES, the mode is set to mode 3 (ST21),
Returning to ST10, NO in ST14, NO in ST18
, And if the determination in ST22 is YES, the bar 9 shown in FIG.
A book blinking operation is performed (ST23). In this mode 3,
It is determined whether the current differential impedance is 1 Ω / s or less (ST24), and if the determination is NO, the process returns to ST10,
The blinking of the nine bars in ST23 is continued as it is.

If the determination in ST24 is YES, that is, if the differential impedance is 1 Ω / s or less, it means that the change in the measured impedance is small and the measurement is being stabilized. The determination as to whether the current impedance is equal to or lower than 1 Ω / s determines whether or not the measurement has reached an end state. Initially, the measurement is in progress while there is a change in impedance.
Subsequently, the mode is set to mode 4 (ST25), and as shown in FIG. 13, 12 bars blink (ST26, ST2).
7). Next, it is determined whether or not the current impedance is 1 Ω or less per second (ST28). If there is still body movement, the measured value of the bioimpedance greatly changes. Therefore, if the current differential impedance exceeds 1 Ω / s, it indicates that a body motion has occurred, and the mode is returned to mode 3 again (ST29). Then, again from ST10, ST 10 in FIG.
Then, the mode is shifted to 22, and mode 3 is displayed, that is, nine bars are blinked (see FIG. 12). This indicates that there has been body movement. Therefore, the user may see the bar display 1 during measurement.
By reducing the number from two to nine, it is possible to know that there has been body movement. Knowing body movement can be a motivation for re-measurement without body movement.

In ST28, if the determination is YES, it is next determined whether or not the differential impedance one second before is 1 Ω / s or less (ST30). If this determination is NO, the process returns to ST10. . If both the differential impedance one second ago and the differential impedance this time are 1 Ω / s or less, it is further determined whether the differential impedance two seconds ago is 1 Ω / s or less (ST 31). ,
Return to ST10, but the differential impedance 2 seconds before is also 1Ω
If the differential impedance is equal to or less than / s, that is, if the differential impedance is equal to or less than the predetermined value for 3 seconds, it is determined that the measurement is completely completed, and the mode is set to mode 5 (ST32), and the process returns to ST10.

Finally, since the mode is mode 5, NO is determined in ST26, and the measurement is terminated. The display of mode 5 is as shown in FIG. The user can know the body fat percentage and the body fat amount by numerical values, and can know the determination result and the degree thereof by a bar graph. In the display example of the measurement result shown in FIG. 14, seven bars are displayed, and the rightmost bar blinks. The display area where the rightmost bar (tip of the bar graph) exists is “light obesity”, and only one bar on the left side of this “light obesity” area is displayed. The degree is "low".

Next, FIGS. 6 and 7 are flowcharts showing another overall operation. This operation is basically the same as the operation shown in FIG. 2, except that the operation of displaying that the input has been completed based on the fact that all the personal data required for the measurement has been input, and the operation of the personal data required for the measurement The operation (protection function) that does not start the measurement unless all are input is added. The same processing as in FIG. 2 will be described briefly.

First, when the power switch is turned on (ST
41), input of personal data is performed (ST42). S
At T43, it is determined whether or not all personal data has been input. If the determination is NO, the measurement start switch is turned on.
/ OFF determination is performed. At this stage, since no personal data has been input, the measurement start switch is turned ON / O.
Regardless of the FF, the process returns to ST42 to continue inputting personal data. When all the personal data is input, the display of "ready" is turned on as shown in FIG. 9 (ST45).
However, in FIG. 9, "ready" is displayed. The user
By looking at the "ready" display, it can be known that all the data has been input.

After the display of "ready", it is determined whether the measurement start switch is ON / OFF (ST46). When the measurement start switch is turned on, the display of "ready" is turned off (ST47). As shown in FIG. 10, the display of "under measurement" is turned on (ST48), and the measurement is started (ST49).
During this measurement, as described above, mode 1, mode 2,
The measurement step proceeds sequentially from mode 3 to mode 4, and FIG.
As shown in FIG. 13, the number of bars displayed increases by three. During this time, the display of “under measurement” is continued.

During the measurement, it is determined whether or not the measurement has been completed (ST50). If the measurement has not been completed, ON / OFF of the measurement start switch is further determined (ST5).
1). During the measurement, the measurement is continued regardless of ON / OFF of the measurement start switch. When the measurement is completed, the measurement result is displayed on the display 1 as shown in FIG. 14 (ST5).
2). In the result display, the display of “under measurement” is turned off and the display of “ready” is turned on. Since the result display is continued for one minute (ST53), ON / OFF of the measurement start switch is determined during one minute (ST5).
4). If the measurement start switch is turned on within one minute, re-measurement is performed, and the process returns to ST47. The display of "Ready" is turned off, the display of "Measuring" is turned on (ST48), and the display returns to the display of FIG. Re-measurement starts. If the measurement start switch is turned on until one minute elapses after the measurement result is displayed, the measurement can be performed any number of times. When one minute has elapsed, the measurement ends.
