Embodiment 1

[0344] Next, the structure and operation of the body composition measuring device according to Embodiment 1 of the present invention will be explained. FIG. 1 is an external view of the body composition measuring device of Example 1. FIG.

[0345] This body composition measuring device flows a weak high-frequency current through the body of the test subject, detects the voltage generated by the current in a predetermined part of the body, calculates the impedance based on the voltage value and the current value, and calculates the impedance from the measured value of the impedance and Externally input body-specific information such as height, weight, age, gender, etc. is applied to the prescribed derivation formula, and arithmetic processing is performed to calculate and prompt the subject’s body fat percentage, fat loss, fat mass, body water content, muscle mass, Muscle strength, bone mass, bone density, obesity, basal metabolism, ADL index value and other body composition inform...

Embodiment 2

[0520] The second embodiment of the body composition measuring device according to the present invention will be described. The body composition measuring device of Example 2 focuses on the wrist or ankle area, which is a body part with a particularly high proportion of the amount of bone tissue in the human body. By attaching a dedicated measuring electrode to this part, the measurement depends on the amount of bone tissue. Based on the measured value and body-specific information, the amount of bone tissue is estimated.

[0521] Figure 38 It is a state diagram of the electrode pad 80 installed near the wrist, Figure 39 It is a perspective view of the appearance of the electrode pad 8. in Figure 39 Here, the base tape 81 is a film sheet made of an insulator such as polyethylene or polyvinyl chloride, and two strip-shaped electrodes 82 made of conductive gel are provided in the base tape 81 at a predetermined interval Lo from each other. On the surface of the base tape 81 wher...

Embodiment 3

[0527] Figure 42 It is a diagram of the usage state of the body composition measuring device of Example 3. The body composition measurement device 40 includes an upper limb measurement unit 41 held by the subject with both hands and a lower limb measurement unit 42 on which the subject puts both feet, and is connected by a cable 43. The functions of the personal computer 1 and the main body 2 corresponding to the body composition measurement device of the first embodiment are incorporated in the upper limb measurement unit 41. Figure 45 It is an external perspective view of the upper limb measurement unit 41. The upper limb measurement unit 41 has a substantially U-shaped main body portion 411 with left and right end portions bent to the rear side, and substantially cylindrical clip portions 412L and 412R are respectively provided at the rear end portions. The energizing electrodes 413L and 413R are provided on the upper and lower side peripheral surfaces of the clip parts 412L...

Abstract

To accurately measure the muscle mass, body-fat ratio and/or other information of the subject, the human body is divided into nine segments including the trunk, right and left forearms, right and left upper arms, right and left thigh, and right and left crura. Four distal voltage-measuring points Pv are determined at the wrists and ankles, and four proximal voltage-measuring points Pv are determined at the elbows and knees. Four current-carrying electrodes and four measuring electrodes are used. First, the measuring electrodes are attached to distal points, and the impedances of four limbs and the trunk are measured. Then, the measuring electrodes are moved to proximal points, and the impedances of four limbs and the trunk are measured. From the measurement result, the measurement value is calculated for each segment. Then, using estimation formulae created by a regression analysis based on the data collected with an MRI, the body composition such as a muscle mass is estimated from the measurement values of the impedances and body specific information including the height, weight, etc.

Description

Technical field [0001] The present invention relates to a body composition measuring method and a body composition measuring device, which measure the bioelectrical impedance of a subject’s body, and use the measured value of the impedance and body-specific information such as height, weight, age, and gender to derive and prompt this The subject’s body fat mass, muscle mass, muscle strength, bone mass, fat loss, body fat rate, basal metabolism and other information related to body composition and health status or physical activity capacity. Background technique [0002] In the past, for obesity and other health management, body weight was usually measured. In recent years, not only physical obesity, but as an indicator of obesity, the amount of body fat such as subcutaneous fat and visceral fat is relative to body fat. The body fat prevention rate in proportion to body weight has attracted people's attention. [0003] Previously, researches such as measuring the bioelectrical imp...
