Patent ID: 7418294

Claim:
An electro-therapeutic device for treating the preferably human body, and/or for carrying out a respirator-triggered, active expiration and/or for the prophylaxis of an inactivity atrophy of the respiratory muscle disorder, with electrical currents of a defined frequency and amplitude, comprising at least two flat electrodes attachable to the body to be treated for closing a current circuit via said body, in connection with which device a treatment current (i B ) whose amplitude (A) and frequency (f) can be modulated simultaneously, can be introduced into the body to be treated, means for varying the treatment current (i B ) within a frequency band (f B ) designated as the medium frequency range between from 1 kHz to 100 kHz, in order to treat the preferably human body, or to carry out said active expiration or to treat said respiratory disorder, in a manner such that it is varied in preferably discrete frequency steps between a first limit value with a low limit frequency (f u ) at a simultaneously minimal amplitude (A u ) of the treatment current (i B ), and a second limit value with an upper limit frequency (f o ) with a maximal amplitude (A o ) of the treatment current (i B ) and a second limit value with an upper limit frequency (f o ) with a minimal amplitude (A u ) of the treatment current (i B ), means for causing amplitude rises or drops as the frequency is simultaneously increasing, or, viceversa, the amplitude (A) of the treatment current (i B ) decreases or rises as the frequency is simultaneously decreasing, and means for modulating the treatment current (i B ) in such a manner that it is varied at least within a part of the treatment frequency band (f B ) between the first and the second limit values in a manner such that it is varied slightly below the threshold based on a stimulation threshold (RS), substantially in parallel with the stimulation threshold (RS), in a manner such that the treatment current (i b ) is always trailing the stimulation threshold (RS) depending upon the amplitude and the frequency, in each case slightly falling short of the sensitivity threshold.
