Abstract
A patient treatment unit for delivering non-invasive pulsed energy to living tissue with a probe stimulus generator circuit configured to output, as a treatment signal, a sequence of DC electrical pulses at a controlled pulse frequency of about 20 kHz and having a pulse voltage defined by a variable supply voltage of the probe stimulus generator circuit. The unit includes primary and secondary probes for contacting a body, an intensity adjustment circuit configured to control the variable supply voltage, and an electronic timer display configured to display an elapsed time in decimal numbers in minute and second format. An electrical current of the pulses is in a range of 0.1-2 mA while the probes are contacting the body. An operating output voltage across the probes while conducting the treatment signal does not exceed a maximum operating output voltage of 165 VDC while the probes are contacting the body.
