DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cosmetic diagnosis apparatus which electrically measures body fat and gives a guideline for cosmetic treatment suitable for a person based on the body data of the person.

[0002]

2. Description of the Related Art In the field of cosmetic treatment and medical treatment, body fat is measured and knowledge of obesity level is used to obtain guidelines for appropriate treatment such as diet, treatment or aerobic exercise. It has been reported by Brozek et al. That the proportion of fat in the human body is related to body density (J. Brozek
et al, Ann NY Acad Sci., 1963, 110; 113-40). In addition, it is reported by Lukaski et al. That the weight excluding fat is proportional to the square of height divided by body impedance (HC Lukaski et al, The American Jo
urnal of Clinical Nutrition, 41 (1985) 810-817).
Since this report, various electrical devices for measuring the proportion of body fat have been developed. The present applicant has already proposed some body fat measuring devices.

[0003] The ratio of body fat is important as a clue for beauty treatment, but even with the same ratio of body fat, according to the individual's basic data, that is, according to the person's gender, age, height, and weight, It may be slightly obese or, on the contrary, somewhat lean. In order to determine the degree of obesity or leanness of this person from the numerical value of the body fat ratio, it is necessary to make a determination based on the basic data of the person. This judgment requires considerable proficiency not only by amateurs but also by those who specialize in beauty treatment. Normally, a large number of tables are prepared for an appropriate range of the body fat ratio, an obese range, and an overly lean range according to gender, age, height, and weight. Appropriate beauty treatment is performed based on the measured value of the body fat ratio.

[0004]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the drawings showing embodiments. FIG. 1 is a general block diagram showing a circuit configuration of a cosmetic diagnosis device according to the present invention. The measurement is based on the so-called four-terminal method.
B is composed of independent four electrodes, electrical signals of the four electrodes via connecting lines L _0, it is introduced to the calibration circuit CAB according to the invention to be described in detail later. The four electrodes of the measurement probe PB are attached to the skin surface of a human body to be measured at predetermined intervals. An applied voltage, in this case a 50 kHz sine wave AC voltage, is applied to the two electrodes. The detection voltage is detected from the remaining two electrodes attached between these electrodes, and the impedance of the body is obtained.

The applied voltage is first generated by the oscillator Os
A 50 kHz sine wave AC voltage is introduced into the drive circuit Dv and further into the primary side of the transformer T1. Then, the output voltage on the secondary side is sent to the measurement probe PB via a changeover switch (not shown in FIG. 1) described later in detail. In an embodiment of the invention, the applied voltage is about 7.5 volts between the peaks. The detected voltage from the measurement probe PB is similarly supplied to a transformer T2 via a changeover switch (not shown in FIG. 1), and an output signal on the secondary side is introduced to a bandpass filter FT. In that case, this filter is composed of a narrow band active filter using an operational amplifier,
The tuning frequency is set to 50 kHz in the embodiment of the present invention. The filtered signal is introduced into a subsequent rectifier circuit RT, converted into a detected DC signal, and subjected to waveform shaping, level adjustment, and offset adjustment by an amplifier Am. The PRB is converted into a body fat value digitally in accordance with a predetermined arithmetic expression. Then, the obtained data is output to an output display section DS including a display device and a printing device. Relevant personal data of the measurement subject, that is, gender, age, height, weight, etc. are input from the input keyboard CB and stored in a predetermined storage location in the central processing unit PRB, and are used when performing related calculations. Is done. Operation of the switch in a said calibration circuit CAB is done by sending the calibration circuit CAB a control signal formed by the central processing unit PRB via conductor L _1. The two transformers T1 and T2 are also used for electrical insulation so that the applied power and the power of the detection processing unit are not directly applied to the human body to be measured. Since the frequency is relatively high, it is advantageous to use a ferrite core for the cores of transformers T1 and T2.

[0010] The switching process is, as shown in the flowchart of FIG. 3, and instructs the start of measurement at the start, first, the changeover switch SW ₁ to SW ₅ to measure the dummy resistor R ₁ switches at step S1. Then, measurement is performed for a predetermined time, for example, 1.5 seconds, and a detection output signal during that time is sent to the central processing unit. Then, by a command from the central processing unit at step S2, it switches to the measurement of the dummy resistor R _2,
Measurement is performed for a predetermined time, for example, 1.5 seconds, and a detection output signal during that time is sent to the central processing unit. Thus, the parameters k and C ₀ are calculated in the central processing unit. When this preparation is completed, the mode is switched to the mode for measuring the human body impedance again according to a command from the central processing unit. This measurement is also performed, for example, for 1.5 seconds, and the result is transmitted to the central processing unit.
It will calculate the final body fat using the parameters k, C _0. The result is output by appropriate means and the measurement process is completed.

The advantage of using the calibration circuit CAB according to the present invention is that the oscillator Os, the narrow band filter FT, the detection circuit RT, and the amplifier Am use extremely stable and reproducible elements or a circuit configuration of such elements. The point is that the measurement can be performed with sufficient accuracy without the need to perform the adjustment, and it is sufficient if the adjustment of various circuits during the manufacturing process and maintenance is performed relatively easily.
In particular, it is worth noting that there is no need to use nerves for block compatibility.

In the cosmetic diagnosis apparatus according to the present invention, the printer can print numerical values of various measurement results, but the above nine patterns of the measurement results, that is, the patterns of the measurement results shown in FIG. Can also be printed.

In the calculation in the beauty diagnosis apparatus according to the present invention, the following calculation is performed by software using the stored numerical values and mathematical expressions. (1) Calculation of Ideal Weight The ideal weight W ₀ (kg) with respect to the input height H (cm) can be expressed as log W ₀ = a + bH. Here, the values of the coefficients a and b are as shown in the following table when the age is T for men and women. Male Female Tabab 20 to 29 2.137 0.01176 2.210 0.01102 30 to 39 2.487 0.00989 2.335 0.01045 40 to 49 2.131 0.01217 2.284 0.01105 50 to 59 1.926 0.01332 2.178 0.01182 60 to 1.826 0.01375 1.815 0.01413 This is quoted from the “Health Promotion Impact Division,“ Judgment Tables / Figures for Obesity and Thinness ””.

In addition, as a simple calculation method, regardless of age, W ₀ = (H−100) · 0.9 for men and W ₀ = 44 + 0.4 · (H−140) for women, etc. Expressions can also be used.

(2) Upper and lower limits of ideal weight The upper limit value WA ₀ and the lower limit value WB ₀ (both in kg) of the ideal weight with respect to the weight (W; kg) of the measurer at that time can employ various methods. In the first method, it is determined according to WA ₀ = 1.10 · W ₀ WB ₀ = 0.90 · W ₀ .

In the second method, it is also possible to use WA ₀ = W ₀ +2 WB ₀ = W ₀ -2.

In general, in the case of cosmetic treatment, the weight is selected to be considerably smaller than the upper and lower limits of the ideal weight recommended by the Ministry of Health and Welfare. (3) Calculation of the ratio of body fat (F;%) from the measured human body impedance (Z; ohm) As described above, referring to the evaluation method of Lucasky and the related formulas such as Blozek, The relational expression suitable for the Japanese to the ratio of the body fat and the body fat was obtained by the experiment.

For a man, F = [4.95 / (1.155−0.084 · W · Z / H ² ) −4.5] · 100 For a woman, F = [1.00− (0.6483 · H ² /Z+0.1699·W+5.091) ) / W] .100 was used. The coefficient used in both equations is 1
All except 00 should be set within the range of ± 10%.

[0027] (4) upper limit for the ratio of the ideal body fat _{(F 0,%) (FA} 0,%) and the lower limit value (FB _0,%) of the measured body fat percentage of the ideal body fat for (F) Ratio (F _0, %) and the upper limit value (F
A ₀ ) and the lower limit (FB ₀ ) are determined using the values in the table below. Gender / age 〜 30 31 〜 40 41 〜 50 51 〜 60 61 〜 FB ₀ 10 10 11 12 14 Male F ₀ 13.5 14.5 15.5 15.5 16 FA ₀ 15 15 16 17 19 FB ₀ 18 18 19 20 22 Female F ₀ 19 20 21 22 23 FA ₀ 23 23 24 25 27 These values can be changed like the above-mentioned ideal weight according to the purpose of beauty.

(5) Recommended Basal Metabolism The basal metabolism (EK; kcal) to be recommended for a person having a body weight (W) and a body fat ratio (F) is obtained from the following equation.

In the case of a man, EK = [27.71 · (100.0−F)] · (W / 100.0) +188.2 40 years and over EK = [25.33 · (100.0−F)] · (W / 100.0) + 243.2 For women 39 years old or younger EK = [24.03 · (100.0-F)] · (W / 100.0) + 427.6 40 years old or older EK = [21.95 · (100.0-F)] · (W / 100.0) + 424.3 last The dot matrix display unit MX according to the present invention
Will be described. It has already been described that there are two types of display in the dot matrix display section MX in the case of the embodiment of the present invention. Dot matrix display section M shown in FIG.
The lighting method of the X light emitting diode is one of them. All the light emitting diodes on the outer periphery are lit in green, and two rows of light emitting diodes 71 and 72 in the vertical direction and two rows 73 and 74 in the horizontal direction are lit green in this display area. The two vertical columns correspond to the lower limit FA ₀ and the upper limit FB ₀ of the proportion of body fat, respectively, and the two horizontal columns correspond to the upper limit WA ₀ and the lower limit WB ₀ of the ideal body weight. FIG. 6 shows a case where both the weight W of the measurer and the ratio F of the measured body fat are within the ideal range. In this case, four light-emitting diodes are illuminated in red at the center grid, indicating that the measurement result of the measurer is within this range. When W is in an ideal range and F is in an excessive range (over-fat), the four light-emitting diodes are not located in the center cell of FIG. Lights up red. If both W and F are in an excessive range (overweight and overfat), the light emitting diode is lit red in the upper right mesh area. Further, when both W and F are in an insufficient range (insufficient weight and insufficient fat), the light emitting diode is illuminated red in the lower right mesh area. Thus, the measurement result is W
And F are classified and displayed in nine areas according to the lacking range, the ideal range, and the excess range, respectively. In the case of this display, as shown in FIG. 6, the lower limit value FA ₀ (15
%) And the upper limit FB ₀ (30%) and the upper limit W of the ideal weight.
A ₀ (55 kg) as the lower limit value WB ₀ (46 kg) is displayed in the display window _{DF 1, DF 2, DW 1} , DW 2 corresponding respectively.

In another display method, as shown in FIG. 7, a doll pattern is formed on the dot matrix display section MX. Diode (black circle R) that lights red outside the doll
) Indicates excessive body weight, and a diode (indicated by a black circle R ') illuminating red inside the doll (around the heart) indicates excessive body fat, and a diode illuminating orange (cross) (Circled) indicates body fat. And the diode (G) lit in green indicates the body weight of the standard body type. In this display, there are nine types of doll patterns in the same manner as in the previous display method, and FIG. 8 shows an arrangement of the doll patterns corresponding to the arrangement of the meshes in FIG.

FIG. 9 illustrates the evaluation corresponding to the mesh positions in FIG. In this regard, the measurement evaluations are described individually and guidance for a preferred cosmetic treatment or health care is given below.

(1) Upper left position (weight is above standard, body fat is below standard) This type is often used by athletes such as wrestling and boxing players, and is muscular and quite heavy. It is strong and has a very high basal metabolic rate. There is a need for a cosmetic treatment that keeps the fat as it is and loses muscle to lose weight. It is hard to say that it is a feminine figure.

(2) Middle left position (weight is within standard, body fat is below standard) This is an ideal type that is common to long distance players. Although it looks slender, it has physical strength and high basal metabolism. I will try to maintain this as I am satisfied with my body composition.

(3) Lower left position (both body weight and fat below standard) Pathological symptoms are often seen. Proper guidance on nutritional balance is necessary. (4) Upper center position (overweight and fat within standard range) This type is often used for short-distance athletes on land and swimming, athletes in karate, bodybuilding, etc. The muscles are plump and fat, but they look lean.
Although he has physical strength and a high basal metabolism, he is an obesity reserve army who tends to become obese or over-fat if he is not alert.

(5) Central position (both body weight and fat within standard range) Ideal type based on healthy standards. Efforts should be made to maintain this condition.

(6) Lower center position (weight is within the standard range, fat is below the standard) When viewed cosmetically, one ideal type. It is desirable to maintain the proportion of body fat even when the body weight fluctuates, to build muscle, and to increase basal metabolism.

(7) Upper right position (a type that can be recognized as obese from any point, in most cases, there is a sense of obesity, but there is often no self-control and no effort alone. There are also signs of adult disease. Be careful, calorie restriction and aerobic exercise are essential.

(8) Center right position (weight is within the standard range and fat is above the standard) Actually, although obese, the awareness of obesity is low. Because of the fact that the body weight is below standard, I am spoiled. Appearance is "wobbly" and weight is lower than apparent. Low basal metabolic rate, easy to get fat, improvement of lifestyle is indispensable, nutrition guidance and aerobic metabolism are indispensable.

(9) Lower right position (body weight below standard and fat) The most dangerous type. Due to its relatively slim appearance and light weight, the surrounding people are not treated as obese, and they do not have any awareness of obesity. Has the lowest basal metabolism and lacks physical fitness.
Very likely to become obese in the future. Very high risk of adult illness. First, you need to recognize that you are clearly obese. Review lifestyle habits and incorporate sufficient aerobic metabolism.

In the beauty diagnosis apparatus according to the present invention, the above classification result can be further conveyed by voice to the person to be measured via the speaker SP to call attention. The resulting short message may use, for example, the types described above. There is also a method of transmitting the contents of each cell in FIG. 9 in the form of audio, and in addition to this, an appropriate countermeasure may be transmitted in a short time.

The above display shows the weight and body fat.
The ratios were classified into three levels, but one for weight and body fat.
Display one or both in 5 levels, in which case the standard range is in the center
