Abstract
A pulse generator for providing timed pulses of adjustable amplitude and constant width for nerve stimulation at selected portions of a body. The timed pulses of positive and negative amplitude are generated alternatinely and the period can be precisely set.
Claims12
A pulse generator circuit for generating timed pulses of regulated amplitude and constant width comprising:
- oscillator means for providing timing pulses;
- trigger circuit means for receiving said timing pulses and for generating trigger signals of predetermined pulse width;
- driver circuit means for receiving said trigger signals and for generating driving signals;
- voltage conversion means for providing adjustable regulated voltages;
- and
- switching means for receiving said driving signals and said adjustable regulated voltages and producing output timed pulses of amplitude equal to said regulated voltages and of constant width.

A nerve stimulating device for stimulating nerves of a body comprising:
- oscillator means for producing variable rate timing pulses;
- trigger circuit means for receiving said timing pulses and for generating trigger signals of predetermined pulse width;
- driver circuit means for receiving said trigger signals and for generating driving signals in response thereto;
- voltage conversion means for providing adjustable regulated voltages;
- and
- switching means for receiving said driving signals and said adjustable regulated voltages and producting output timed pulses of amplitude equal to said regulated voltages and of constant width;
- and
- electrode means connected to said switching means and adapted to be secured to a selected area of a body so that said timed pulses stimulate the nerves at said selected area.
