ABSTRACT:
A breast pump includes a housing, a suction unit mounted in the housing, a rippled funnel for engaging a mother's breast, and an adapter for interconnecting same. The adapter is configured to sealingly support the funnel, frictionally sealingly support a bottle for collecting milk, and frictionally sealingly engage the housing. The adapter includes a tubular protrusion/stem defining a passageway for communicating air from the bottle to the suction unit to create a vacuum in the bottle. A pair of "O" rings are positioned on the protrusion to sealingly and stably engage the housing. A check valve is located in the protrusion to prevent back flow of milk from the bottle to the suction unit. The housing includes an outer surface defining a hand grip, and vacuum adjustment controls including a wheel for fine vacuum adjustment and a vacuum releasing push bottom are conveniently positioned on the hand grip. The housing includes a shroud that protects the bottle and that forms a stable arrangement that the entire unit will stand upright on a table. The shroud defines a battery holder and further includes a jack for mateably engaging an AC/DC transformer outlet for optional operation of the motor in lieu of batteries. The hand grip and the battery placement provide an optimal center of gravity located below the hand grip so that the breast pump can be easily, comfortably and securely held. The funnel includes three ring-shaped undulations providing increased comfort, size adaption and functionality to the funnel.
