20080255503 | Method and apparatus for minimum negative pressure control, particularly for breastpump with breastshield pressure control system - 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. | 10-16-2008 |

The device can be used manually, worn within a bra, or used with a breastshield of a breastpump. | 01-29-2009 |
20090099511 | Method and Apparatus for Minimum Negative Pressure Control, Particularly for a Breastpump with Breastshield Pressure Control System - 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).

20100121267 | Breastshield With Multi-Pressure and Expansible Chamber Construction, Related Breastpump and Method - Inner and outer shield parts of a breastshield are joined to form an enclosure defining a pressurizable chamber. The inner shield part has at least a portion thereof movable relative to the outer shield part when the chamber is subject to a negative or a positive pressure. A first pressure port is in communication respectively with the chamber for connection with a fluid pressure source of a first pressure. A second pressure port is in communication with the interior for connection with a pressure source of a second pressure. The breastshield is thus capable of being subjected to two different pressures, such as a positive pressure to move (expand) the chamber into the interior, so as to compress or massage the nipple/breast, and a negative pressure in the interior to draw the nipple/breast further therein for the expression of milk. The pressures can be independently controlled, and may furthermore alternate being negative and positive through the same pressure port. In one embodiment, an enclosure defines first and second chambers. The chambers are separate from each other and independently pressurizable. A greater plurality of chambers is furthermore contemplated. The invention takes the form of a variety of different embodiments of breastshields and breastpumps for breastmilk pumping having sundry novel attributes and advantages. | 05-13-2010 |

20110071466 | HIGHLY EFFICIENT BREASTPUMP AND SYSTEM FOR EXPRESSING BREASTMILK - 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. | 03-24-2011 |
20110168292 | Container with Sealed Cap and Venting System - A bulk feed adapter cap for a collection container comprises: (a) a housing defining both at least one fluid-communication opening and one or more air-release openings and (b) a membrane defining an annular, self-sealing fluid-valve for sealing said fluid-communication opening, where the fluid-valve defines at least one aperture. The bulk feed adapter cap may further comprise at least one fluid-communication cap. | 07-14-2011 |
20110240586 | Artificial Nipple With Reinforcement - The invention is directed to an improved feeding nipple, including a substantially solid nipple portion.

20120277728 | DEVICE AND METHOD FOR EXPRESSING HUMAN BREAST MILK - A device for expressing human breast milk has a breast shield for bearing against a mother's breast, a vacuum pump for generating a vacuum, a line which connects the vacuum pump to the breast shield and is intended for transmitting the vacuum generated to the breast shield, and a chamber. The line ends on the pump side in a first port of the chamber. The chamber has a second port for connection to a milk collecting container. The two ports in the chamber are connected to each other in terms of fluid communication. During the expressing operation, the line forms a milk line for transporting breast milk expressed in the breast shield to the chamber and from the chamber to the milk collecting container. The pump can be designed to be quiet and small. | 11-01-2012 |
20120316493 | BREAST SHIELD FOR EXPRESSING HUMAN BREAST MILK - A breast shield has a tubular connector and a funnel that is integrally formed thereon, and is intended for resting on a mother's breast. The funnel widens toward the free side thereof which faces away from the connector. A passage, which extends continuously from a breast-side end of the funnel as far as a pump-side end, being opposite the breast-side end, of the connector, and serves to apply a vacuum to the mother's breast and for the flowing away of the expressed breast milk. The funnel is of more flexible design than the connector, and the funnel has a main region extending over a substantial part of the length thereof with a first opening angle of the passage, and a breast-side end region with a second opening angle of the passage. When not in use, the first opening angle is smaller than the second opening angle. In use, at least the first opening angle can be enlarged by axial pressure on the breast shield. The breast shield is pleasant to wear and minimizes the dead volume. | 12-13-2012 |
