A hands-free breast pump system is disclosed. A breast shield having an adhesive inner surface for adhering to a woman's breast is disclosed. The breast shield may be connected to an adapter for transferring a vacuum generated by a pump to the breast. The adapter also allows milk expressed from the breast to drain from the adapter to a container. In the alternative, the breast shield may form part of a breast shield adapter system which is connected to a conventional breast shield by a drain line so that a conventional breast pump system is used to supply a vacuum and to collect the milk.

A device for expression and collection of breast milk includes an actuatable assembly, a breast interface, and a tube. The breast interface is sized to receive a breast and form a fluid tight seal against the breast. The breast interface includes a deformable member disposed within at least a portion of the breast interface. The deformable member deforms in response to actuation of the actuatable assembly and applies vacuum pressure against the breast to express milk. The tube operatively couples the actuatable assembly to the breast interface.

The present invention provides a breastshield for use in a breastpumping system for expressing milk, the breastshield being of such a construction that substantially limits the amount of air between the breast/nipple and the breastshield surrounding the breast/nipple, and most preferably virtually eliminates any air at least in the area of the breast and nipple. In some embodiments, any air in the breastpumping system is substantially eliminated. With the amount of air limited, the mechanism used for generating the pressure difference in the breastshield (e.g., vacuum or negative pressure), such as a diaphragm pump, does not need to do as much work. Less energy is required for the expression of milk, and thus the size of pump used can be decreased, thereby reducing the overall cost of the device.

Disclosed herein are biologically inspired, either manual or electronic, portable fluid expression system to be used for, but not limited to, breast milk expression from nursing women and other milk expression from any species of mammal. The fluid expression systems can be configured to mimic the anatomy of a suckling infant and the biomechanics and fluid dynamics associated with this behavior. The fluid expression system can be used by nursing mothers to express breast milk efficiently, painlessly, and discreetly. The systems can include a single, contiguous flexible structure designed to resemble the lips and oropharyngeal cavity of a newborn infant of the mammalian species of interest. Rigid external housings or stiffening structures can be used to mimic the bony anatomy of the infant or mammalian species of interest.

A breast pump is disclosed. According to an aspect of a present invention, there is provided the breast pump comprising a contact housing comprising a protruding part configured to correspond to a mother's nipple and extend toward a front; a cap connector coupled to cover the protruding part to form a first inner space; a funnel connector on the cap connector to form a second inner space; a linking pathway between the funnel connector and the cap connector and configured to link the second inner space of the funnel connector with the first inner space of the cap connector; a storage housing comprising a coupling hole to correspond to the second inner space of the funnel connector and coupled with the contact housing; a lid coupled to cover the second inner space of the funnel connector through the coupling hole of the storage housing; a flow separation membrane configured to divide and separate the second inner space between the funnel connector and the lid; an air pathway in the lid through which air flows into and out from a space between the lid and the flow separation membrane; and an attachable pump module on the lid to suck the air between the lid and the flow separation membrane through the air pathway, wherein the attachable pump module is integrally coupled with the lid to be detachably coupled to the coupling hole.

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 device is disclosed. The breast pump device includes a primary machine portion, and a secondary control portion provided separately from the primary machine portion. The primary machine portion further includes a main housing, a pump attached to the main housing and configured to generate a pressure to cause breast milk to be expressed by a user of the breast pump device, and a milk container coupled to the pump and configured to accommodate the breast milk. The secondary control portion is electrically coupled to the primary machine portion without an airway and configured to remotely operate the primary machine portion.
