  • Publication number: 20180028731
    Abstract: A barrier of a vacuum pump prevents contamination from entering a vacuum pump air line. The barrier separates parts of the pump and is moveable between an initial state and a distended state. The barrier is assembled within the pump with a pre-load. When the vacuum source is applied to the barrier, the barrier achieves a distended state and when the vacuum source is released, the barrier incrementally self returns to an initial state. The geometry and material construction of the barrier, along with the pre-load, assists in returning the barrier on its own to the initial state from the distended state.

  • Patent number: 9296531
    Abstract: 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.

  • Patent number: 8273057
    Abstract: The connector provides fewer connections and attachments to a breastpump configured for expressing breast milk from both of a woman's breasts simultaneously, thereby facilitating easier use of the breast pump and yielding fewer pieces for the user to carry or misplace. The connector includes a manifold with four ports. Individual tubes extend from three of the four ports and each has a plug member. One tube engages with a vacuum source and the remaining two tubes engage with a breastshield assembly for double breast pumping. When single breastpumping is desired, one of the two tubes connected to the breastpump assemblies is disconnected and engaged with the dock port of the manifold.

  • Patent number: 8096824
    Abstract: A connector for connecting a tube within a receptacle. A latching component fits within the receptacle, and receives a plug member to which the tube is connected. One end of receptacle is adapted, for instance, to be attached to a tube on a motor drive unit of a breast pump assembly, or formed integrally therewith. The opposite end of receptacle receives components of the connector therein. The plug member is inserted into the latching component and has means thereon that engage corresponding means on the latching component such that the plug member is releasably secured within the latching component in a rotatable manner.

  • Patent number: 8070716
    Abstract: 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.

  • Publication number: 20100224525
    Abstract: The present invention provides for pressure indication within the vacuum storage container, as well as a way to isolate mother's milk in a container from air. The present invention utilizes sub-atmospheric pressure to reduce, or at least slow down, the oxidation reactions in breastmilk in order to preserve vitamins, lipids, and other important compounds in the milk, and includes means to measure that sub-atmospheric pressure, so as to provide indications to the user that the correct container pressure has been obtained and maintained.
