ABSTRACT:
A transcutaneous electrical nerve stimulator in which a unijunction transistor relaxation oscillator is used to produce variable frequency, variable width pulses. The relaxation oscillator drives a two stage transistor amplifier and the output therefrom is transformer coupled to a set of output electrodes which are adapted to be placed on the area of a patient to be treated. The amplitude of the signals applied to the patient as well as the rate and duration thereof are controllable so that the patient may adjust the nerve stimulation to suit his particular needs.
