METHOD OF GENERATING ELECTRIC PULSE FOR BIOLOGIC OBJECTS STIMULATION AND APPARATUS THEREOF

摘要

METHOD OF GENERATING ELECTRIC PULSES FOR BIOLOGIC OBJECTS STIMULATION AND APPARATUS THEREOF The method comprises the steps of generating pulses with a specified repetition rate, duration modulating each pulse, arranging stimulating pulses into packages of specified duration with specified pauses between packets, amplifying the stimulating pulses in the packet, varying the duration of the pulse packet applied to the object in accordance with an estimate of the electrophysiologic parameters of the state of the interelectrode section of the biologic object, this assessment being carried out simultaneously with stimulation. The electric pulse generator of this method comprises a pulse generator, a pulse duration modulator, a stimulating pulse power amplifier, a first signal shaper to detect the object's response to stimulation, a variable-duration pulse generator to set the duration of pulse packets, a second signal shaper to produce signals of the pulse packet duration, and a modulation control signal-clipper.
