Bioelectrical impedance measuring apparatus

A bioelectrical impedance measuring apparatus characterized in that it comprises:

• a rest on which one selected body region may be put;
• a pair of current electrodes so placed on the rest that the one selected body region may be put in contact with the current electrodes;
• a pair of voltage electrodes so placed on the contact surface between the pair of current electrodes that the one selected body region may be put in contact with the voltage electrodes;
• a position member which permits the one selected body region to be put in correct position;
• an alternating current supplying device which supplies the pair of current electrodes with alternating current;
• a voltage measuring device which measures the voltage appearing between the pair of voltage electrodes;
• and
• an arithmetic unit which calculates the bioelectrical impedance from the supplying alternating current and the measured voltage.
