Abstract
The invention relates to an apparatus for electrotherapeutic treatment of the human body, which has electrodes that can be laid against the body and a device for producing a therapy current that flows through the body, by way of the electrodes, whereby the device for generating the therapy current comprises two oscillators having frequencies f1 and f2 that lie close to one another and are suitable for forming a beat, an oscillator having a frequency f3 that is less than the beat frequency fs1=f1−f2, and a mixer device for superimposition of the oscillator signals. According to the invention, the device for producing the therapy current comprises at least two additional oscillators with frequencies f4 and f5, and the mixer device is provided with frequencies f1 to f5 for superimposition of all oscillators.

Apparatus for electrotherapeutic treatment of a human body,
- which has a unit for producing a therapy current that flows through the body and electrodes that are connected to the unit and that can be laid against the body for conducting the therapy current,
- wherein the unit comprises two oscillators having frequencies f1 and f2 that lie close to one another and are suitable for forming a beat, an oscillator having a frequency f3 that is less than a beat frequency fs1=f1−f2, and
- a mixer device for superimposition of the oscillator signals, wherein for improving the skin tolerance of the treatment and for stimulating regions that lie deep in the body the unit for generating the therapy current comprises at least two further oscillators having frequencies f4 and f5, and
- the mixer device is provided for superimposition of the signals of all the oscillators having the frequencies f1 to f5, wherein the frequencies f4 and f5 which are suitable for forming a beat frequency fs2 that is greater than fs1.
