Description

According to another aspect of the present invention, the thumbs of both hands are inserted in a bioelectricity impedance measuring apparatus of the type in which the palms of both hands are arranged substantially opposite to each other with a predetermined gap and lifted with both hands. A pair of thumb insertion holes, a pair of thumb electrodes on which the thumbs of both hands inserted in the pair of thumb insertion holes are in contact, and a pair of palm electrodes on which the palms of both hands are in contact An alternating current supply means for supplying an alternating current to a pair of palm electrodes, a voltage measuring means for measuring a voltage between the pair of thumb electrodes , a supplied alternating current, and the measured voltage. There is provided a bioelectrical impedance measuring device comprising the computing means for computing bioelectrical impedance.

In step 11, the subject presses the operation key 26 to input an instruction to start measurement. Then, facing the front of the housing 21, the left thumb is inserted into the left thumb insertion hole 22a, the inserted thumb is disposed in contact with the left thumb electrode 23a, and the left palm is disposed in contact with the left palm electrode 24a. Similarly, the thumb of the right hand is inserted into the right thumb insertion hole 22b, the inserted thumb is placed in contact with the right thumb electrode 23b, and the palm of the right hand is placed in contact with the right palm electrode 24b. When the two hands are arranged on the main measuring device 20 in this manner, the palms of the two hands are arranged at both ends of the main measuring device 20 so as to substantially face each other at a predetermined interval. In this state, the measurement device 20 is lifted from the left and right ends with both hands, in particular, the palm of the hand, and in the standing position, the measurement is performed by stretching both arms substantially horizontally to the front of the body. As described above, when measuring the bioelectric impedance using the present measuring device 20, the subject inserts the thumbs of both hands into the thumb insertion holes 22a and 22b and places the both hands in the present measuring device 20. The insertion holes 22a and 22b function as positioning members for determining the orientation and position of both hands, so that the subject can always place both hands on the main measuring device 20 with the same position and orientation of both hands. The same measurement posture can be maintained between measurements or during measurement. In addition, since the subject places particularly the palm of both hands in contact with the palm electrodes 24a and 24b, the contact area of these is wider than in the conventional case where the finger is placed in contact with the electrodes. The contact resistance of this portion is smaller than in the conventional case where the finger is placed in contact with the electrode and measured. Also, since the person to be measured lifts with both hands, especially with the palm, without using an indirect force on the wrist or arm such as in the conventional case where the device is gripped and measured with a finger The measurement can be carried out by lifting the measuring device 20. Furthermore, the subject inserts the thumbs of both hands into the thumb insertion holes 22a and 22b and lifts the measuring device 20 in a state where the thumbs extend substantially horizontally, so the force of the palm of both hands during measurement Even if it has come off, the measuring device 20 is caught on the thumb and does not fall off.
