Abstract

(57) [Abstract] [Purpose] To improve the internal fat mass meter, which calculates the amount of internal fat from physical characteristics such as height, weight, impedance between terminals, and sex, so that it can be easily and accurately measured. [Structure] The electrodes for measuring the impedance between the terminals of the body are installed on the platform of the electronic scale at a position where they contact both legs in an upright posture, and the electronic height meter is placed at a position where the electrodes can be measured in the upright posture for impedance measurement. A display unit is provided so as to face the height meter, and impedance, weight, and height are measured at the same time and automatically input to display the calculation result.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a body fat mass meter, and more particularly to a body fat mass meter that can easily and accurately calculate the fat mass in the body from the physical conditions such as the impedance between the terminal ends of the body and the height and weight. .

[0002]

[Prior Art]

 As an accurate and convenient method, the impedance between the ends of the body is measured with a 4-terminal Kelvin Bridge bioimpedance meter, and the amount of body fat is calculated from the value and the values related to the body such as height, weight and sex of the sample The calculation method is proposed as USP 4,080,712 and USP 4,895,163 (Japanese Patent Laid-Open No. 2-60626).

In these methods, since the degree of flexion and the degree of opening angle of each joint affect the impedance value, in order to eliminate these error factors, the measurement posture of the subject and the joint are laid down on the bed or the like. The conditions are constant.

In addition, if the distance between the current supply terminal and the voltage detection terminal of the impedance detection electrode cannot be sufficiently secured, the measured value will be affected, and as a countermeasure, the current supply terminal will be placed on the back of the hand and foot. The voltage detection terminals are attached to the tendons of the wrist and ankle to obtain the distance.

The body fat amount is calculated by calculating the body end impedance value measured by the above measuring device and the body weight and height measured separately.

[0006] For these reasons, there is a large restriction on the measurement location (a bed or the like is required), and it is difficult for the person to be measured to measure by himself, and there is a risk of erroneous input of each measurement value. It also included sex.

[0007]

[Problems to be solved by the device]

 This is to eliminate the restrictions on the measurement location and make it easy for the person to be measured to measure it alone.

[0008]

[Means for Solving the Problems]

 Place the impedance measuring electrode on the platform of the electronic scale, measure the impedance between the ends of the body between both legs in the upright posture, and place the electronic height meter at a position where it can be measured in the upright posture for impedance measurement. , A display unit is installed facing the height meter, and impedance, weight and height are measured at the same time, and the results are automatically displayed and the calculation results are displayed.

【Example】

 FIG. 1 is a perspective view showing an outline of an embodiment of the present invention.

(3) is an electronic scale that converts the weight of the object to be measured on the mounting table into an electronic amount and outputs the electronic quantity. The mounting table is covered with an insulating material.

The platform of the electronic scale (3) is provided with a heel guide (4) for allowing the measurer to always rest at the same position, and the impedance between the two feet when placed at a predetermined position in an upright posture is measured. For measurement, the heel electrode (5), which is the voltage detection terminal, and the toe electrode (6), which is the current supply terminal, are fixed in pairs on the left and right.

In order to eliminate the influence of the potential distribution, the heel electrode and the toe electrode should be spaced at a distance of 5 cm or more at the closest portion, and the right and left foot electrodes should be in contact with the legs of the measurer. Instead, fix it symmetrically at a position where it can stably assume an upright posture.

When the measurer takes an upright posture on the electrode to measure the impedance, the electronic height meter (1) is installed at a position to detect the crown position.

It is desirable that the height meter uses a non-contact distance meter that measures the distance between a sensor fixed to a certain height by reflection of ultrasonic waves and the reflection surface (crown).

The display unit is installed at a position where the person to be measured can easily operate and read the displayed value in an upright posture while facing the height meter.

[0016]

[Effect of the device]

 By taking an upright posture at a predetermined position, not only can all the physical characteristics that have to be measured and input to calculate the body fat mass be input, but the posture for measuring height can be adjusted to both knees, The joints such as the waist and back muscles will be stretched to a certain extent, which automatically satisfies the essential condition for accurately measuring the impedance between both legs and has a remarkable effect that accurate measurement can be performed extremely easily. It is a thing.
