TO ALL WHOM IT MAY CONCERN:
Be it known that I, JAMES COLE, of Brooklyn, in the county of Kings, and State of New York, have inveited a new and' useful Improvement in Breast-Pumps, of which the following is a full, clear, and exact description, reference being had to the'accompanying` drawing, forming part of this specifidation, and which representsa longitudinal sectional view of a breast-pump construeted according to my improvement.
The nature of my invention consists in a combination of an ela-stic sack or bulb with induetion and eductionvalves, and flexible pipes or tubes branching therefrom in opposite directions, and provided, the-one branch with a breast-eup and the other branch with a discharging-nozzle.
Referring to the aceompanying drawing, A represents a rubber saek or bulb, made of any suitable shape to admit of its being conveniently graspod and worked by the hand. B B' 'are flexible tubular conneetions therefrom, fitted preferahly at their junction by screw-couplings a a, with the bull), or the latter at its ends, 'with an induetion and eduction-valve, b b'. The one of these tubes, B, terminates in a breast-cup, O, made of glass, metal, or other suitable material, other than soft or flexible, and shaped to cover the nipple of the breast, while the other tube, 13/, terminates in a glass, metal, or other suitable nozzle, D, to conveniently direct the discharge intol a cup or reeeiving-vessel.
The operation of the instrument is as follows': The breast-eup C being stifi" or inflexible, is firmly held over the nipple of the breast, with a gentle pressure, suifieiently hard to prevent air from entering the cup. The
bulb A with the vother hand is then alternately compressed and relaxed, which action procluces a suct'ion or` exhausting effect, eausing themilk to fiow, and when suiiiciently eontinued, to be discharged through the nozzle D into the cup or vessel in which saidnozz'le rests. w
A pump thus constructed, approximates in its operation the natural' action of a child in sucking', has no injurious spasmodie effect, and does not product an unsightly elongation or inflammation of the nipple, causing strangulation of the milk-veins. It can be self-applied, and with the nicest regulation as regards force, according to the condition of the breast, and with but little effort, for if, necessary, a lengthened p'ericd of time. In these or other respects, it importantly difi'ers from many or most breast-pumps, and though having certain features in common with some and with certain enema-syringes, its functions or appendages are clifl'erent, and as an entirety is as new as it is useful. i
Having thus described the invention, what I claim, and desire to secure by Letters Patent, is-- A breast-pump, construetod substantally a's described.
