  • Method for inducing uterine activity through nipple stimulation
    Patent number: 4794915
    Abstract: A method for mechanically stimulating the nipples of a pregnant woman for diagnostic and therapeutic effects. A nipple stimulator device is placed over a woman's nipple, and an intermittent reduced pressure is induced in the interior of the apparatus by a pump. An elastic membrane on the stimulator device is drawn inward by the reduced pressure, and in so doing acts to massage the breast nipple and the adjacent breast. A gentle, soft massage of the nipple is thereby provided to yield the desired stimulation to produce hormones, for example, useful in accelerating labor or conducting contraction stress tests in a pregnant woman.
