Abstract
Abstract A nursing apparatus is utilized for stimulating lactation in the female human breast. A breast receiving opening permits the positioning of the apparatus over the female breast, and means for pressurizing and depressurizing an attached chamber then operates to provide a suction action. Additional stimulation is provided by an electrically powered vibrator, while the breast receiving portion includes a chamber which may be filled with warm water to thus simulate the temperature of an infant's mouth.

Claim 1
Independent Claim
335 words
A nursing apparatus, comprising: a. milk receiving and collecting means having a substantially cylindrical shape; b. breast engaging means engageable with a female breast, said breast engaging means having a substantially concave shape, said breast engaging means being fixedly secured to a conduit, said conduit being fixedly secured to and in fluid communication with said milk receiving and collecting means, said breast engaging means including within its concavity a nipple engaging portion, said nipple engaging portion having a substantially ovoid shape to simulate the shape of a baby's mouth; c. suction bulb in fluid communication with said nipple engaging portion, said suction bulb also being in fluid communication with said conduit, said suction bulb including a one way valve for creating a partion vacuum in said bulb thereby exerting a negative pressure on said nipple for effecting a removal of milk from said breast, said milk travelling through said nipple engaging portion into said suction bulb and from thence through said conduit into said milk receiving and collection means, said milk being prevented from flowing from said milk receiving and collection means into said suction bulb by a one way valve in said conduit means; d. first stimulation means, said first stimulation means comprising a temperature control means, said temperature control means comprising a warm fluid holding chamber located between an outer and an inner wall of said breast engaging means, said warm fluid holding chamber being filled with a warm fluid to control a temperature of said breast engaging means, said warm fluid being introducible into said fluid holding chamber through a valve fixedly secured to an outer surface of said outer wall of said fluid holding chamber and in fluid communication with said fluid holding chamber; and, e. second stimulation means, said second stimulation means including an electrically powered vibrator operably attached to said suction bulb so as to effect a vibration in said bulb, said vibration being communicated to said nipple engaging portion thereby to simulate the experience of a nursing infant.
