A wearable breast pump system is provided. The wearable breast pump system can include a housing having a pump, a breast flange, and a milk container. The pump can form part of a closed loop system that drives a separate, deformable diaphragm to generate negative air pressure. The diaphragm can be removably mounted on a breast shield.

The invention is a wearable breast pump system including a housing shaped at least in part to fit inside a bra and a piezo air-pump. The piezo air-pump is fitted in the housing and forms part of a closed loop system that drives a separate, deformable diaphragm to generate negative air pressure. The diaphragm is removably mounted on a breast shield.

A breast pump comprises an outer housing for mounting over the breast and an inner breast shield which is transparent at least in the region of the nipple. The outer housing has a window in an upper portion of the outer housing, for enabling, in use, a direct line of sight for the user of the breast pump, through the window to the nipple. The remainder of the outer housing blocks a view of the nipple from at least directly in front.

A breast milk collection and storage system is disclosed that comprises a manual breast pump. The manual breast pump comprises a breast cup configured to engage with a mother's breast. The breast cup comprises an opening. The manual breast pump also comprises a reservoir at a base of the breast cup configured to receive breast milk through the opening and collect breast milk extracted from the mother's breast. The breast milk collection and storage system also comprises a stopper configured to seal the opening to prevent leakage of breast milk from the reservoir. The breast milk collection and storage system further comprises a capsule configured to enclose the manual breast pump with the stopper and apply a compression force to the stopper to maintain the seal of the opening when the capsule is closed.

A breast pump device and associated methods for extracting breast milk ate disclosed. A pump head comprises an external shell with an elastic membrane disposed and bonded therein to define at least one hermetically sealed chamber. Manipulation of the elastic membrane, for example, by adjusting suction or pressure in the sealed chamber or within an interior volume defined by the elastic membrane permits radial mechanical compression (positive pressure) to be applied to a nipple positioned in the pump head to simulate compression of the nipple by the infant's tongue and simultaneously permits axial hydraulic or pneumatic suction (negative pressure) to be applied to the nipple to simulate the infant's minimum intra-oral vacuum. The breast pump device of the present invention can generate these simultaneous compressions and suctions with a single vacuum source, which may be an electric pump or a hand-operated mechanical pump.
