Abstract: A portable, battery-powered, self-contained electroanesthesia device. A signal generator provides a sinusoidal, constant magnitude signal of fixed, preset frequency with relatively high accuracy and without recalibration each time the device is energized. The preset frequency characteristically produces electroanesthetic induction in a live subject with relatively high efficiency. An amplifier increases the power level sufficiently for producing electroanesthetic induction of the subject. Electrodes supply the amplified signal to tissue of the subject, there being provision for matching the impedance of said tissue of the subject to the amplifier for maximizing transfer of the amplified signal to said tissue. Circuitry is provided also for monitoring and limiting the power level of the signal supplied by said electrodes to the tissue.
