Patent number: 7381197Abstract: A vacuum control system controls the amount of time that pressure is applied to a breast and the amount of time no pressure is applied to the breast, independent of the vacuum level. The amount of time that pressure is applied to a breast and the amount of vacuum applied to the breast cups can be varied by the user. A disposable biological filter isolates the pump from the breast cups. The biological filter is packaged in a housing that has an O-ring push-in connector to connect the collection system to the pump. The vacuum applied to the breast cups is monitored. The control system maintains the vacuum at a level set by the user. A second higher level is used as a safety threshold. The control system shuts down the pump when this higher level is sensed. The breast cup is constructed to provide a controlled collapse when vacuum is applied to mimic the suckling of an infant.Type: GrantFiled: August 20, 2003Date of Patent: June 3, 2008Inventors: Patricia A.

Patent number: 7166087Abstract: 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.Type: GrantFiled: July 15, 2003Date of Patent: January 23, 2007Assignee: Medela Holding AGInventors: Brian H.

Publication number: 20040199107Abstract: The invention relates to a breast-milk pump containing a breast cup, a suction connection that can be connected to the suction pump and a blocking device which seals the suction connection against the entry of milk. The pump is provided with a valve housing, containing an inlet that leads to the breast cup, an opening connected to the suction pump and a valve body. The valve body contains a cladding surface and a closing surface, which together form a hollow body, whose opening faces towards the inlet. The hollow body is mounted on a support so that one side can freely pivot. If during a suction phase, the level of milk that has risen above the collection container reaches the inlet, a stream of milk enters the hollow body.Type: ApplicationFiled: April 4, 2003Publication date: October 7, 2004Applicant: Nuesch EngineeringInventor: Hansueli Nuesch

Publication number: 20040158199Abstract: A device for expressing milk from one or more breasts has at least one, and preferably two expressers and a pump. The expressers each have a cup for fitting on the breasts and a cup outlet to which a vacuum created by the pump can be connected. The cups have a flexible liner which collapses around the breast to establish the vacuum. Pulsating pressure is applied to the outside of the liner to increase the vacuum and stimulate milk production. The pressure is applied through lines which are vented to maintain adequate, consistent pressure pulses without stalling the pump.Type: ApplicationFiled: January 26, 2004Publication date: August 12, 2004Applicants: Whittlestone,Inc, L.

Patent number: 6764377Abstract: A disclosed breast milk expression system supports a pair of breast milk collection devices at the breasts of a nursing mother, allowing her to express breast milk while keeping her hands free. No special bra or other garment is required to provide support. The system includes a substantially rigid bar, a strap, and a pair of breast milk collection device connectors at or near opposite ends of the bar. The strap is comprised of a length of slender, flexible support material, significantly longer than the bar. The strap extends from a point at or near one end of the bar to a point at or near another end of the bar and can suspend from a nursing mother's neck, thereby suspending a pair of breast milk collection devices near the nursing mother's breasts to express milk from them. Numerous variations and methods are also disclosed.Type: GrantFiled: May 9, 2002Date of Patent: July 20, 2004Inventor: Jonathan C. Gillan
