Bipolar electrodes discharging sparks of piezo-electric origin for the relief of pains and contractures by direct application to the skin

摘要

Bipolar electrodes discharge sparks of piezoelectric origin. The poles (4, 5) of the electrodes are less than a centimeter apart in order to avoid a double discharge and to provide better stimulation. A separation device (7) is placed between them; this device is substantially longer than the length of the electrodes (4, 5) so as automatically to distance the electrodes from the skin. This separation device also serves as insulation to prevent interdischarge of the electrodes.
