发明名称 Transcutaneous pain control and/or muscle stimulating apparatus
摘要 An apparatus for generating electrical pulses which are suitable for application to selected areas of the user's body for pain control or muscle stimulation. The current level, pulse width, pulse rate, voltage level and pulse configuration are all controlled to produce the desired effects. The apparatus includes a timing circuit which emits pulses of selected width and repetition rate. The pulses from the timing circuit energize a switching circuit which selectively connects the primary of a pulse transformer to a power source. The transformer is so constructed and arranged that it operates near saturation, thereby effectively operating as a current limiter, which helps to prevent spikes in the electrical pulse output of the apparatus.
