Abstract
Abstract An apparatus for electrical stimulation of the mammae comprises a serial arrangement of a master oscillator, a stimulating pulse generator, an amplitude modulator, a stimulating pulse polarity changing unit, an output unit, and a distributing line with leads for respective points subject to electrical stimulation. In addition, the apparatus comprises modulating signal generator and a unit to form excitation and space periods, which connect each other and the frequency and amplitude modulators as well, and also comprises an automatic stimulating pulse polarity control unit coupled to the stimulating pulse generator, to the modulating signal generator, and to the stimulating pulse polarity changing unit. There is a stimulating pulse amplitude adjustment circuit for each of the points subject to electrical stimulation, coupled to a matching unit which connects surface-type electrodes.
