Abstract

(57) [Summary] [Purpose] Impedance between terminal parts of the body and height, weight,
Eliminate the restriction on the measurement location of the internal fat mass meter that calculates the amount of fat in the body based on physical conditions such as gender, so that the person to be measured can measure easily by himself. [Composition] When standing upright on it, measure the impedance between both feet so that it contacts each of the heels and toes of both feet. 4
Fix one electrode by projecting it onto the insulating base (1). In order to eliminate the measurement error, the heel electrode (3) and the toe electrode (4) should be spaced by 5 cm or more, and a heel guide should be provided to keep the foot position constant, depending on the foot size. The electrodes for the toes are made vertically long to eliminate errors.

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 a method of accurately and simply measuring the amount of fat in the body, the impedance between the ends of the body was measured with a 4-terminal Kelvin Bridge bioimpedance meter, and from the value and the numerical values related to the body such as height, weight and sex of the sample, Methods for calculating the amount of fat in the body have been proposed as USP 4,008,712 and USP 4,895,163 (JP-A-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.

For these reasons, there is a large restriction on the measurement place (a bed or the like is required), and it is difficult for the person to be measured to measure by himself.

[0006]

[Problems to be solved by the device]

 It is to eliminate the restriction on the measurement location and put into practical use a device that can be easily measured by the person under test.

[0007]

[Means for Solving the Problems]

 The four electrodes for the foot position are used to ensure that the four electrodes for impedance measurement are placed on the soles of the subject's feet in an upright posture, so that the electrodes are securely attached at appropriate intervals. It is projected and fixed onto the insulating member provided with the guide to be an integrated member.

【Example】

 FIG. 1 is a plan view of an embodiment of the present invention, and FIG. 2 is a sectional view taken along line AA.

When a foot electrode (3) and a toe electrode (4) forming a conductive pair are placed on a base (1) formed of an insulating member, and the feet are placed on each other, Install symmetrically at intervals such that they can stably assume an upright posture without contact.

Each electrode is fixed so as to project from the base to ensure contact with the sole of the foot.

Further, in order to eliminate the influence of the potential distribution, the closest portion between the heel electrode (3) and the toe electrode (4) is provided with an interval of 5 cm or more, and the toe electrode (4) is varied. Its shape is oval (oval) to accommodate large feet.

The toe electrode (4) is used as a current supply electrode, and the heel electrode (3) is used as a voltage detection terminal.

A heel guide (2) is provided behind the heel electrode (3) on the base (1) so that the user can always get on a certain position by contacting the heel and getting on the heel. It is provided.

[0014]

[Effect of the device]

 The in-body fat meter according to the present invention allows a person to be measured to stand on a designated position and to stand upright, and the person to be measured can easily repeat the measurement under the same conditions.

Further, since the measurement can be performed in the upright posture, the restriction on the installation location of the measuring device is remarkably reduced.
