Electrode apparatus for measuring impedance within the human body, and apparatus using same for measuring impedance within the human body and performing treatment
An electrode device for measuring impedances of a human body is disclosed. The electrode device includes a cylindrical housing member (10) with a guide rod (11) mounted to the housing member (10). A cylindrical electrode member (30) is configured to move back and forth through the open side along the guide rod (11). A resilient member such as a spring (20) is interposed between the cylindrical electrode member (30) and the cylindrical housing member (10) to move the electrode member back and forth along the guide rod (11) as the electrode is pressed against the skin.
