ABSTRACT:
A therapeutic device including a voltage adjustment for outputting an adjusted AC signal to a load. The adjusted AC signal has an amplitude between 0 and 100 volts and a low commercial frequency. To create and output this signal, the device accepts an input voltage from a commercially available power supply and uses a pair of contact electrodes attached to two arbitrarily selected points on the load. The device has an electrical current setting circuit which assigns a prescribed current set value between the selected points. The actual therapeutic electric current applied between these points is a function of the setting of the voltage adjustment and of the load resistance between these points. A comparing circuit in the therapeutic device compares the therapeutic electric current flowing between the two points with the prescribed current set value. If the therapeutic electric current is larger than the prescribed current set value, then the comparing circuit causes an output switch to interrupt the supply of the adjusted voltage to the pair of contact electrodes. In the specified embodiments of this device, the load between the contact electrodes includes a series connection between a therapist and a patient.
