ABSTRACT:
An electromedical apparatus for generating low-frequency magnetic fields for magnetic field therapy or treatments by the Kraus & Lechner method includes an oscillator and amplifier (10, 12) for generating low-frequency electrical oscillations of adjustable frequency and amplitude, and at least one applicator coil (32) for generating a low-frequency magnetic field corresponding to the electrical oscillations. Switching on of the apparatus and initiation of a treatment cycle is by actuating a single key switch (56, 58). The apparatus is normally switched off after expiry of a treatment period by a time switching device (80) but it can also be switched off by a fault detection circuit (88) which automatically switches the apparatus off on occurrence of disturbances. With this step operating errors and damage to the apparatus by disturbances are avoided even when the apparatus is used by laymen at home without supervision.
