PIEZOELECTRIC STIMULATOR Russian patent published in 2000 - IPC

FIELD: medical equipment, in particular, devices of electrophysical influence, applicable for neurostimulation and medical influence by means of stimulation of biologically active zone of the human body surface and activation of the regeneration processes at traumata and postoperative intervention. SUBSTANCE: piezoelectric stimulator is provided with a selector switch linked with a key through a tie-rod, and a contact washer made for its connection to an electrode unit, all positioned in the body. The regulator is made as a movable carriage, whose lower tapered end serves as a contactor. The selector switch outputs are electrically connected to the contactor and current lead of the electrode unit contact washer respectively. The inputs are connected to the outputs of the piezoelectric oscillator. The influence electrode of the electrode unit may be made with one working end in the form of a tapered end-piece. It may be T-shaped. The electrode unit may be made with a deadened spherical working end. The electrode unit may be cone-shaped with a through duct and funnel-shaped inner surface. EFFECT: enhanced range of control of the influence signal and formation of influence parameters of preset polarity. 5 cl, 3 dwg
