Apparatus for generating positive and negative electric pulses for application to a living body for therapeutic purposes
First Claim
1. Apparatus for generating positive and negative electrical pulses for application to a living body for therapeutic purposes comprising pulse generating means for producing at the output terminals thereof a succession of pairs of electrical pulses of opposite polarity and with adjustable repetition rate, pulse separating means for adjusting the time interval between pulses of opposite polarity of each pair of pulses and for supplying positive pulses to a first output terminal and negative pulses to a second output terminal, first pulse forming means connected to the first output terminal for adjusting the amplitude and width of the positive pulses, second pulse forming means connected to the second output terminal for adjusting the amplitude and width of the negative pulses, and output means for combining the pulses from the first and second pulse forming circuit into an output signal of the apparatus.

Abstract
Apparatus for treating organisms for therapeutic purposes consists in applying thereto by means of electrodes an electrical signal comprising successive pairs of pulses, the pulses of each pair being of opposite polarity. The apparatus has an electrode arrangement for application to the organism and a signal generator for supplying to the electrode arrangement the signal comprising successive pairs of pulses, the pulses of each pair being of opposite polarity. The generator has controls for varying independently of one another the amplitude of the pulses of each polarity, the duration of the pulses of each polarity, the interval between the pulses of each pair, and the interval between successive pairs of pulses.
