Abstract
Current stimulation apparatus, in particular, exhibits an output stage as the current waveform generator for producing an output current through a patient's body as the load resistance. Such apparatus operates with a specifiable operating voltage and controls the patient current in a constant-current fashion in the case of a varying load resistance. Preferably, the patient current is here measured through determination of the voltage across defined resistance terminals, whereby magnitude as well as peak values can be displayed on the display units associated with the output stage. Up to the present time, the measuring and display units had been fed by power supply units which deliver a supply voltage in relation to operating potential. According to the disclosure, all units for measuring, further processing, and/or display of the patient current are decoupled from the operating voltage circuit and receive supply voltages which are directly defined in relation to ground potential.
