A breast pump device and associated methods for extracting breast milk are 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.

The human nipple functions for both nutritive and non-nutritive suckling with the only difference that in the first instance nutritive fluid is delivered. The present invention conflates these two suckling devices. A nipple device comprises a first reinforcing member provided at the exterior surface of a nipple portion, and surrounding an interior elastomeric core. A second reinforcing member, such as a mesh reinforcement, can be added to improve bite resistance without compromising stretchiness or compressibility. The nipple device is bite-resistant to guard against biting damage and stretching-to-failure by an infant; and compressible, so forces applied by an infant's tongue will be transmitted (in the case of an artificial feeding teat) through a solid nipple core to compress and shutoff central duct(s) to facilitate swallowing without gagging, or (in the case of a pacifier) to reshape the nipple portion so it conforms to the shape of the infant's oral cavity.

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.

A pump apparatus and method for extracting breastmilk is disclosed. A pump head comprises a funnel-shaped breast shield portion and a neck portion leading to a collection container. A deformable elastic component is sealed within an opening formed in the neck portion and manipulated to engage the user's nipple to simulate the suckling of an infant. The deformable elastic component is configured to move into the interior volume of the neck portion under an applied positive pressure to compress the nipple and control nipple edema. The deformable elastic component is also configured to move away from the axial center of the neck portion under an applied negative pressure to create suction and extract breastmilk in a manner that closely replicates the suckling of an infant. The pump may also include another deformable elastic component to stimulate a Milk Ejection Reflex (MER).

A manual pump apparatus and method for extracting breastmilk is disclosed. A pump head comprises a funnel-shaped breast shield portion and a neck portion leading to a collection container. A deformable elastic component is sealed within an opening formed in the neck portion and manipulated by a mechanical actuation device to engage the user's nipple within the pump head to simulate the suckling of an infant and to compress the nipple to control edema. The deformable elastic component is configured to move into the interior volume of the neck portion under an applied pressure such that the deformable elastic component compresses the nipple to control nipple edema. The deformable elastic component is also configured to move away from the axial center of the neck portion under an applied pressure to create a volume to create suction and extract breastmilk in a manner that closely replicates the suckling of an infant.

Manual breast pump

A pump apparatus and method for extracting breast milk is disclosed. The pump includes a first interface component to stimulate a Milk Ejection Reflex (MER) and a second interface component to extract breast milk. Milk is extracted through an improved method that more closely replicates the suckling of an infant.

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.

Highly efficient breastpump and system for expressing breastmilk

A bite-safe artificial nipple is constructed of polymeric materials sufficiently soft and elastic to replicate a nursing mother's nipple tissue. Added to the soft, elastic matrix phase is a braided fibrous mesh tube to prevent a small bitten-off portion of the nipple from becoming separated from the rest of the teat, thereby preventing a choking hazard. The braided fibrous mesh tube is arranged in a very specific configuration, so that it experiences neither tension nor compression as the teat is compressed or elongated in use and so does not act to 'reinforce' the soft, elastic matrix phase which would otherwise create a classic load-transfer composite destroying the soft, elastic properties of the matrix phase needed for the desired functioning of the artificial teat.

Bite-safe artificial teat

A breastpump, manual or motorized, that includes a mechanism to regulate pressure change, e.g., vacuum, within a breastshield chamber, including in some cases to a maintained minimum pressure that is less than ambient (atmosphere). The pressure regulator provides control for varying negative pressure between a minimum value and a maximum value (and values in between), or to achieve a specific actually measured negative pressure value within a breastshield.
