  • Patent number: 4761160
    Abstract: The invention provides a system with hardware useful for artificial milk extraction from the human breast. Included is a conical breast cup placed over the mother's breast and a mouth piece on which the mother sucks. The sucking regulates a vacuum created in a baby bottle when air is removed through a tube in a vacuum cap on the bottle. The vacuum expresses milk from the nursing mother's breast similar to a suckling baby. The milk is drawn from the conical breast cup, along a milk tube, and into the baby bottle through a milk stem opening in the vacuum cap. During sucking, the vacuum created in the system holds the conical breast cup in position and allows the mother use of both hands. The filled baby bottle is then caped and the milk stored for future use.
