Abstract
In the case of current stimulation apparatus, in particular, protection installations are necessary which, in every instance, disconnect the patient from the operating voltage of the apparatus when maximally permissible patient currents are exceeded. For this purpose, for example, safety fuses or also electromagnetic disconnection devices (relays) are known. In accordance with the disclosure, a safety circuit for disconnecting the patient output from the operating voltage is employed as the protection installation which also responds when the patient current deviates from a preselected desired value adjusted on an intensity adjustment member. For this purpose, an output stage as current waveform generator for constant-current stimulation current is connected with the safety circuit.
