Abstract:
1. A patient treatment unit for analyzing and treating abnormality of human or animal tissues, comprising: a pulse generator circuit having current and voltage limiting means and outputs a sequence of electrical pulses at a pulse frequency not exceeding 1 GHz when treating a pain condition of a patient, the electrical pulses having a pulse width less than 0.74 milliseconds and a peak voltage not exceeding about 120 volts; the pulse generator circuit controlling the pulse frequency, the pulse width, or the pulse shape of the electrical pulses, a circuit for detecting an overvoltage or overcurrent in the electrical pulses; a pair of probes for contacting a body of a patient and electrically coupled to the pulse generator each of the probes being separately connected to the patient treatment unit by first and second wires, a treatment control for adjusting the intensity of the electrical pulses; wherein the probes are configured to be applied to the skin of the body of the patient for relieving pain, an audio or visual component indicating an impedance of the skin of the body of the patient as the pulse generator circuit is outputting the electrical pulses to the pair of probes; wherein the maximum current output of the pulse generator circuit is not greater than 8.9 milliamps when the probes are applied to the body of the patient, and wherein the maximum charge of the electrical pulse does not exceed 7 micro-coulombs.
