A hydraulic pumping system in accordance with embodiments comprises a breast interface operably coupled to an actuatable assembly by means of an actuatable assembly interface. The breast interface comprises a distal membrane coupled to a housing to form a fluid reservoir therebetween. The actuatable assembly interface comprises a proximal membrane. The distal and proximal membranes are fluidly coupled via a tube carrying a driving fluid. The actuatable assembly interface is configured to removably couple to the actuatable assembly, in order to operably couple the actuatable assembly to the breast interface. The actuatable assembly interface comprises a fluid shut off mechanism to reversibly shut off fluid communication between the breast interface and the actuatable assembly interface when the actuatable assembly interface is decoupled from the actuatable assembly.

A biomechanical breast pump mechanism (1) for expressing breastmilk comprising a biomimetic funnel (2), at least two active actuation areas (23,24) on the funnel (2) and stationary areas (25), the active actuation areas (23,24) being actuatable by a driving mechanism or mechanisms (3) and being configured to replicate the complex functions of the infant's tongue during suckling namely the physical stimulation of the areola (17)/nipple (16); nipple positioning; creating and maintaining low-level baseline vacuum to create air-seal on the breast; generating sub-atmospheric pressure inside the funnel (2); creating and maintaining close-to-zero-air environment in the funnel (2); and control of the vacuum oscillation within predefined ranges coordinated negative and positive actuation (41,42) of one or both actuation areas (23,24) independently or simultaneously.

An example breast pump system can include: a control unit including a processor and memory, the control unit including an interface to control the breast pump system; a vacuum unit controlled by the control unit, the vacuum unit including pump motors to create suction for pumping milk; a support mechanism located remotely from the control unit; and a member extending between the control unit and the support mechanism, the member being movable to allow the control unit to be repositioned relative to the support mechanism. The memory encodes instructions which, when executed by the processor, cause the breast pump system to: select at least a first pump motor from the plurality of pump motors for a first pumping timeframe; and select at least a second pump motor from the plurality of pump motors for a second pumping timeframe.

A pump device as may be used in a breast pump assembly including a pump configured to put fluid in motion, a housing accommodating the pump, at least one fluid transporting conduit connected to the pump, the at least one conduit extending between the pump and the housing, thereby connecting the pump to a position at the housing where the housing is provided with at least one opening for allowing fluid to pass, and a mounting arrangement for mounting the pump in the housing. The at least one conduit is part of the mounting arrangement and has flexible properties to reduce an extent to which vibrations of the pump are transferred to the housing through the mounting arrangement during operation of the device.

A system for hands-free nursing and breast pumping includes a breast compression device with a plurality of thermoformed fluid bladders designed to fit adjustably against each breast and inflate and deflate with minimal power requirements. The compression device and its controller fit inside of a nursing garment designed to receive the device and controller for optimal compression. The nursing garment and the compression device have openings over the nipples so that a breast pump flange can be inserted through them and used in a typical manner for the extraction of breast milk, thus increasing the amount of milk expressed.

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 system embodied in an article of clothing for synchronizing one or more breast-pumping sessions of an individual (such as a mother) and milk consumption by a second individual (such as a baby or infant) is described. In particular, based on measurements of a volume of the collected milk as a function of time and received information specifying milk consumption by the second individual as a function of time, a control circuit may determine a need for milk. Then, the control circuit may provide feedback based on the determined need for milk that synchronizes the one or more breast-pumping sessions and the milk consumption. For example, the feedback may alert the individual to initiate a breast-pumping session and/or may provide a signal to a breast pump that initiates a breast-pumping session.

An apparatus for biomimetic expression of breast milk can comprise a breast interface having an expandable membrane configured to mimic the geometry of an infant's mouth. Various regions of the expandable membrane may be configured to simulate the structure and/or function of various parts of an infant's mouth. The expandable membrane may comprise one or more of a distal sealing region configured to simulate the lips, a superior region configured to simulate the hard palate, an inferior protruding region configured to simulate the gums, an intermediate curved region configured to simulate the tongue, and one or more internal expansion regions configured to simulate the soft palate and the throat. The expandable membrane may have a varying thickness throughout the one or more various regions to enable movement of the regions similar to the movement of the corresponding regions of an infant's mouth during nursing.
