Problems solved by technology

[0011] However, in Patent Documents 1 and 2, only the impedance between the feet or the hands can be measured, and the impedance of the whole body cannot be accurately measured due to the influence of daily fluctuations such as edema. body composition
Since the impedance of the whole body is measured in Patent Documents 3 and 4, compared with Patent Documents 1 and 2, the body composition of the whole body can be measured more accurately, but the user must bring the hands and feet into contact with the electrodes every time the measurement is performed, so The operation is very cumbersome
[0012] In addition, in Patent Document 5, the 8-electrode mode and the 4-electrode mode can be switched, but in the case of the 4-electrode mode (especially between the two feet), there will be Affected by daily fluctuations such as edema, the measurement accuracy of body composition is lower compared to the 8-electrode model
Therefore, when the same measurer uses two modes, there is a problem that the matching of body composition measurement values ​​cannot be obtained

Embodiment approach 1

[0074]

[0075] refer to figure 1 , the body composition meter 100 in Embodiment 1 of the present invention is composed of an upper limb unit 1 that can be held by the subject with both hands, a lower limb unit 2 that can place both feet of the subject, and a The cable 3 electrically connects the unit 2.

[0076] The upper limb unit 1 includes a main body 10a, and handles 10b and 10c respectively provided on the left and right of the main body 10a. The main body 10a is provided with a display unit 15 for displaying measurement results and various information, and an operation unit 16 operated by the subject to receive instructions from the subject or input of various information. A plurality of electrodes E11, E12, E13, E14 are provided on the handles 10b, 10c. The handles 10b and 10c are configured to be able to be held by the subject with both hands. Electrodes E11 and E13 are provided on the handle 10b for the left hand, and electrodes E12 and E14 are provided on the h...

Embodiment approach 2

[0176] Next, Embodiment 2 of the present invention will be described.

[0177] In Embodiment 1 described above, the correction value of the impedance of both limbs is used as relevant information. In Embodiment 2, the correlation between the whole body composition calculated from the whole body impedance and the whole body composition calculated from the impedance of both limbs is set as correlation information. In addition, the appearance and hardware configuration of the body composition meter of the second embodiment are the same as those of the body composition meter 100 of the first embodiment. Therefore, here use figure 1 , 2 The symbols shown are explained.

[0178] Next, differences from Embodiment 1 will be described.

[0179] However, the control unit in the second embodiment is different from the control unit 12 in the first embodiment in terms of functions. Therefore, it is described as the control unit 12A in this embodiment.

[0180] Referring to FIG. 15 , ...

Embodiment approach 3

[0217] Next, Embodiment 3 of the present invention will be described.

[0218] In Embodiment 1, the correction value of the impedance of both limbs is used as relevant information. In Embodiment 2, however, the correlation between the whole body composition calculated from the whole body impedance and the whole body composition calculated from the limb impedance is used as the relevant information.

[0219] In Embodiment 3, the correlation between the whole body impedance and the impedance of both limbs is used as the relevant information. In addition, the appearance and hardware configuration of the body composition meter in the third embodiment are the same as those of the body composition meter 100 in the first and second embodiments. Therefore, here also use figure 1 , 2 The symbols shown are explained.

[0220] Hereinafter, differences from Embodiment 1 will be mainly described.

[0221] Here, the control unit in the third embodiment differs in function from the cont...

Abstract

The invention provides a body composition meter comprising a detecting section (11) for detecting a first potential difference between a hand and a leg of subject by applying a current between the hand and leg through a hand electrode and a leg electrode and a second potential difference between the hands or the legs of the subject by applying a current between the hands or the legs through either the hand electrodes or the leg electrodes, a first body composition calculating section (103) for calculating a first whole-body composition by using the whole-body impedance based on the detection result of the first potential difference, a correcting section (104) for correcting the two-limb impedance according to the detection result of the second potential difference, and a second body composition calculating section (105) for calculating a second whole-body composition by using the corrected two-limb impedance.

Description

technical field [0001] The present invention relates to a body composition meter, and more particularly to a body composition meter capable of calculating body composition (body composition) by a bioelectrical impedance method. Background technique [0002] Conventionally, there is a body composition meter that calculates the body composition of a subject by the bioelectrical impedance method. Such a body composition meter is used for health management of a subject. However, the calculation method (estimation method) of the body composition varies depending on the device. [0003] For example, there is a method of calculating body composition based on the impedance between the hands or feet. In Japanese Unexamined Patent Publication No. 62-169023 (hereinafter referred to as Patent Document 1), it is disclosed that an electrode that is in contact with the foot or hand of the person to be measured is provided for measuring the impedance between the extremities of the body. ...
