Estimating the term…
The invention relates to an ultrasonic therapeutic device, which can be operated independently of an external power source. For longer periods of operation, for example by a trainer at a sports ground, the device can be operated using an external battery stack and for stationary operation, the electric power can be drawn from the mains supply. For reasons of safety, the emitted ultrasonic intensity is reduced in relation to medical therapeutic devices. The same device can be used to heat or cool the area to be treated. The device can also be set to emit electrical, magnetic and electromagnetic fields and for electro-physiotherapy with or without a separate second electrode. The emission head (1) therefore contains an oscillating element (3), Peltier elements (25) for heating and cooling and the electrodes (28, 29, 30) for electro-physiotherapy.
A hand-held device, in particular for therapeutic treatment with ultrasound, wherein it includes a handle (15) and an emitting head (1) for emission of ultrasonic waves, whereby a piezoelectric crystal, a piezoceramic or a piezoelectric film is mounted on the rear side of a membrane (2) as the active piezoelectric oscillating element (3) in a housing of the emitting head (1);
The hand-held device as claimed in any one of preceding claims, wherein an external power pack or battery pack may be used as the power source;
