Patent number: 8192396Abstract: An adapter for use in connecting a vacuum source with a breast shield is disclosed including a housing with at least one female coupling component formed therein, at least one male coupling component that is adapted to attach to a tube at one end for conveying pressure from the vacuum source, while the other end is sized and shaped to be received in the female coupling component. A passageway extends between the first end and the second end of the male coupling component for conveying the pressure. The female coupling component is defined therein by an interior sidewall that has a channel formed therein open to the female coupling component at least somewhere along the interior sidewall. When the male coupling component is inserted in the female coupling component, a sealing portion of the male coupling component engages the interior sidewall surface such that ambient air is prevented from entering the channel and disrupting optimal vacuum pressure.Type: GrantFiled: October 11, 2010Date of Patent: June 5, 2012Assignee: Medela Holding AGInventors: Larry D.

Patent number: 7255681Abstract: A motorized pump is disclosed that includes a flexible diaphragm fitting within a rigid member, a motor drive mechanism for drawing a puller member attached to the diaphragm away from the rigid member to create a space between the diaphragm and the rigid member and form a negative pressure region within that space, and an outlet communicating with the negative pressure region. In one embodiment, the pump provides a negative pressure in a single chamber which can be used to operate one or two breast shield assembles. In another embodiment, the pump is particularly adapted for double-pumping and provides two chambers which generate vacuum.Type: GrantFiled: June 12, 2000Date of Patent: August 14, 2007Assignee: Medela Holding AGInventors: Brian H.

Patent number: 6699213Abstract: A prophylactic device for protecting the diaphragm of a pump, such as a diaphragm pump for a breastpump, from fluid (air/milk) is disclosed. A removably mounted flexible cover is located between the shell of the pump and the movable diaphragm membrane within the shell which isolates the membrane from fluid. The cover is removable for at least one of cleaning and disposal. The flexible membrane has a circumferential rim upon which the cover is received over the rim. The shell has an internal opening defined therein sized to encompass the rim with the cover mounted on the rim in a substantially airtight fit. The cover thereby forms a gasket between the rim and shell.Type: GrantFiled: December 30, 1999Date of Patent: March 2, 2004Assignee: Medela Holding AGInventors: Larry D. Annis, Brian H.

Patent number: 6481986Abstract: An improved vacuum adjustment mechanism for controlling airflow into a chamber which is subject to negative pressure, such as the chamber of a diaphragm pump which is generating vacuum for a breast shield assembly, has an air inlet conduit communicating with the chamber. A channel is formed in a base member, with the channel having a longitudinal length and a dimension perpendicular to that length. The perpendicular dimension varies from a minimum to a maximum. The channel has a bottom and is open, such as along a channel top. An airhole is formed in the channel bottom at the point of the maximum dimension. A rotary member is mounted on the base member, and has an internal channel extending across the longitudinal length of the base member channel, and overlies the channel top. The internal channel of the rotary member communicates with an air source, such as ambient air.Type: GrantFiled: September 29, 2000Date of Patent: November 19, 2002Assignee: Medela Holding AGInventors: Brian H.

Patent number: 5556008Abstract: An improved feeding utensil which includes a container for liquid and a soft spoon shaped feeding portion which receives liquid from the container for feeding, such as for feeding an infant. A preferred embodiment has a one-way valve which functions to allow liquid to flow out from the container into a liquid delivery element, the latter including a reservoir portion for temporarily storing liquid that has passed from the container through the one-way valve, and a spoon shaped feeding portion adapted for feeding the liquid received from the reservoir portion. The liquid delivery element is constructed of soft plastic material or natural or synthetic rubber material. The flexibility of this material facilitates metering of the liquid and also provides a familiar textured feeding cup for inserting into the mouth that is being fed.Type: GrantFiled: April 8, 1994Date of Patent: September 17, 1996Assignee: Medela, Inc.Inventors: Brian H.
