Abstract:
A bioelectrical impedance measuring apparatus characterized in that it comprises:a housing having a contact surface to be applied to one selected body region, the housing having a first pair of current electrodes, a first pair of voltage electrodes, an alternative current supplying device, a voltage measuring device and an arithmetic unit equipped therewith; the first pair of current electrodes so placed on the contact surface that the one selected body region may be put in contact with the current electrodes; and the first pair of voltage electrodes so placed on the contact surface between the pair of current electrodes that the selected one body region may be put in contact with the voltage electrodes; the alternating current supplying device supplying the first pair of current electrodes with alternating current; the voltage measuring device measuring the voltage appearing between the pair of voltage electrodes; and the arithmetic unit calculating the bioelectrical impedance from the supplying alternating current and the measured voltage; wherein the first pair of current electrodes and the first pair of voltage electrodes stand in one line.
