Problems solved by technology

[0004] However, it is difficult to precisely position a tape measure or strap-like device in the proper place on the abdomen
For example, placing a tape measure at a desired height is a very difficult and cumbersome operation because the tape measure may move, especially when the person is standing
[0005] In addition, it is difficult to maintain the position of the tape measure without tightening the part to be measured
Even with the tape ruler in place, tightening the part to be measured can deform the part, causing measurement errors

no. 1 approach

[0045]A body composition determination device according to a first embodiment of the present invention includes a waist circumference calculation device. The waist calculation means measures the abdominal width value of a lying human body, and calculates the subject's waist circumference based on a previously stored correlation between the human abdominal width value and waist circumference. The correlation is represented by a formula determined based on the statistics of the relationship between the waist circumference of a person and the abdominal width value of a person measured using CT (Computerized Axial Tomography). The body composition determining device further includes an abdominal bioelectrical impedance measuring unit for measuring the bioelectrical impedance (bioimpedance) of the abdomen of the human body, and determines the body composition based on the calculated waist circumference and the measured bioelectrical impedance. Composition indicators.

no. 2 approach

[0085] Referring to FIGS. 8 to 14 , a waist calculation device 101 according to a second embodiment of the present invention will be described. Unlike the body composition determining device 1 according to the first embodiment, the device 101 does not measure bioelectrical impedance or calculate a body composition index.

[0086] As shown in FIGS. 8 to 11 , the waist measurement device 101 includes a portable support 114 instead of the support 14 in the first embodiment. As shown in FIGS. 10 and 11 , the support 114 is placed horizontally on the front surface of the human body 20 . The support 114 is provided with a leveling assistance unit 119 (eg, a spirit level or an angle sensor) for assisting an operator in adjusting the support 114 to be horizontal (ie, parallel to the floor or the surface of the bed 30 ).

[0087] The support 114 has a contact portion 120 . The contact portion 120 is a concave portion of a curved shape that can be fitted on the front surface of the ab...

no. 3 approach

[0119] Referring to FIGS. 15 to 19 , a waist calculation device 201 according to a third embodiment of the present invention will be described. Unlike the first embodiment, the waist circumference calculation device 201 calculates the waist circumference of a standing human body 20, and does not measure bioelectrical impedance or calculate body composition indexes.

[0120] As shown in FIG. 15 , the waist calculation device 201 includes: a base plate 190 on which the human body 20 stands; a rod (ie, column) 192 vertically erected on the base plate 190 ; A reference line 196 is drawn on the upper surface of the base plate 190 , and the toes of the human body 20 should be aligned on the reference line 196 .

[0121] The support member 214 has a pair of horizontally extending parallel arms 203a and 203b, and a connecting portion 202 with both ends connected to the arms 203a and 203b. Because the support 214 is a generally rectangular frame with one side open, the support 214 can...

Abstract

An abdomen width determiner determines an abdomen width value of a human subject. A memory stores a correlation between abdomen width values and waist circumferences of human beings. A waist circumference calculator calculates a waist circumference of the human subject on the basis of the abdomen width value determined by the abdomen width determiner and the correlation stored in the memory. The correlation stored in the memory may be expressed by the following regression formula: Y = aX + b where ''Y'' is a waist circumference of a human being, ''X'' is an abdomen width value of a human being, and ''a'' and ''b'' are constants.

Description

technical field [0001] The present invention relates to a waist circumference calculation device for calculating the waist circumference of a human body, and also relates to a body composition determination device including the waist circumference calculation device. Background technique [0002] In the fields of medical treatment, beauty and health care, waist circumference has been widely used as one of indicators related to a person's physique or body shape. As lifestyle-related diseases such as those caused by obesity are currently gaining more attention, the waist circumference is attracting attention because it is considered as an index reflecting the amount of visceral fat, so it is used as data for diagnosing metabolic syndrome. [0003] Waist circumference is usually measured with a tape measure. In addition, Japanese Patent Application Laid-Open No. 11-113870 (published in 1999) discloses a belt-shaped measuring device that can be wrapped around the abdomen of a h...
