Abstract:
1. A body fat measurement device for measuring a body fat mass of a subject's body having an abdomen surface, a back surface opposite to the abdomen surface, hands and feet, said device comprising: multiple electrode arrangements for making contact with predetermined areas of a surface of the subject's body; a body impedance measurement unit configured to perform a measurement of a body impedance of the subject's body using the multiple electrode arrangements; and a body fat mass calculation unit configured to perform the measurement of the body fat mass based on the body impedance measured by the body impedance measurement unit, wherein the multiple electrode arrangements comprise at least a back area electrode arrangement for making contact with the back surface of the subject, and an upper limb electrode arrangement for making contact with a surface of at least one of the hands of the subject; the body fat measurement device further comprising a fitting unit for bringing the back area electrode arrangement into contact with the back surface of the subject in a pressurized state, when the fitting unit is in a fitted state; the fitting unit including a frame member comprising a rear frame portion, a first side frame portion extending from one end of the rear frame portion, a second side frame portion extending from an other end of the rear frame portion, and a front frame portion extending from the first side frame portion; wherein the back area electrode arrangement is provided on the rear frame portion so that the back area electrode arrangement contacts with the back surface of the subject when in the fitted state; wherein the upper limb electrode arrangement is provided at least on any one of the first side frame, the second side frame, or the front frame; and wherein the rear frame portion and the front frame portion are spaced a predetermined distance so that the front frame portion and the subject's abdomen surface do not come in contact when in the fitted state, the body fat measurement device further comprising a display unit configured to perform the display of the body fat mass calculated by the body fat mass calculation unit, said display unit being provided on the front frame portion of the frame member so as to face upward when in the fitted state.
