MEDICAL STIMULATOR WITH STIMULATION SIGNAL CHARACTERISTICS MODULATED AS A FUNCTION OF STIMULATION SIGNAL FREQUENCY |
摘要 |
A transcutaneous electrical nerve stimulation (TENS) apparatus includes first, second, and third oscillators. The first oscillator produces a first train of pulses at a main frequency. The second oscillator produces a second train of pulses at a modulation frequency. Output levels of the second train of pulses vary as a function of the modulation frequency. A frequency control simultaneously controls both the main and modulation frequencies. The third oscillator is responsive to the first and second oscillators and produces a third train of pulses at the main frequency. Intensity and frequency of the pulses of the third pulse train are modulated as a function of the output levels of the second train of pulses. An output driver responsive to the third oscillator converts the third train of pulses into a train of stimulation pulses having electrical characteristics adapted to be applied to a human body to suppress pain. |
