Patent number: 9138516Abstract: In an apparatus for recognizing couplings between a first and a second component of a system, one of the two components is provided with an identification unit. A checking unit is operatively connected to the second component. The identification unit contains an item of information relating to the first component. The checking unit is designed for recognizing and processing this item of information. The checking unit moreover is designed such that, as a function of a result of the processing of the item of information, it allows or prevents coupling between the first and the second component. This apparatus enables a combined use of system components only in the case of an admissible coupling thereof.Type: GrantFiled: January 9, 2013Date of Patent: September 22, 2015Assignee: MEDELA HOLDING AGInventors: Peter Vischer, Urs Koch, Daniela Wäckerlin

Patent number: 8991627Abstract: A teat unit for a feeding bottle has a teat and an adjustment mechanism. The teat can be changed, in terms of its shape or stiffness, by the adjustment mechanism. In this way, one and the same teat can be used with different outward forms. The teat can be adapted to the needs of the baby before or during feeding.Type: GrantFiled: December 2, 2009Date of Patent: March 31, 2015Assignee: Medela Holding AGInventor: Peter Vischer

Patent number: 8960465Abstract: A teat unit for sucking a liquid from a liquid container includes a teat and a flow restrictor with a through-opening. The teat comprises a mouthpiece, with a suction opening, and a main body which is formed integrally on the mouthpiece and widens relative to the mouthpiece. The flow restrictor defines a maximum flow of the liquid passing through the suction opening from the liquid container. According to the invention, the flow restrictor is arranged outside the mouthpiece, and the suction opening has a greater cross-sectional surface area than the through-opening of the flow restrictor. The teat unit permits a feeding action that is as true to nature as possible, since the mouthpiece can be deformed very considerably, without substantially impairing the flow restriction.Type: GrantFiled: November 5, 2013Date of Patent: February 24, 2015Assignee: Medela Holding AGInventors: Erich Pfenniger, Peter Vischer, Mario Rigert, Leon Robert Mitoulas

Patent number: 8647300Abstract: The device according to the invention for connecting a suction hose has a connecting piece which is designed in such a way that the suction hose can be pushed over a region of the connecting piece in a sealing manner. The device also comprises a sleeve which can be pushed over the aforementioned region of the connecting piece, at least partially covering said piece and leaving room between the sleeve and the connecting piece for the suction hose. The connection between the sleeve and the connecting piece can only be separated by the destruction of at least one of said two parts. The design of the exterior of the sleeve prevents a second suction hose from lying in a sealing manner against the sleeve. A suction hose that is connected in a sealing manner to the claimed device can therefore not be removed without destroying the device. In addition, it is impossible to push a hose with a greater diameter onto the sleeve in a sealing manner.Type: GrantFiled: October 24, 2008Date of Patent: February 11, 2014Assignee: Medela Holding AGInventors: Hansruedi Künzler, Peter Vischer, Urs Stadelmann

Patent number: 8646632Abstract: A mouthpiece has a bite-off-prevention feature. The mouthpiece has been manufactured from an elastomeric parent material with at least one first component, where a reinforcing component embedded within the parent material forms the bite-off-prevention feature and derives from the same group of substances or group of materials as the first component. The reinforcing component is preferably composed of fibers.Type: GrantFiled: January 27, 2009Date of Patent: February 11, 2014Assignee: Medela Holding AGInventors: Peter Vischer, Beda Weber, Erich Pfenniger, Stefan Baumann

Patent number: 8079482Abstract: A teat for connection to a receiving unit of a drink container has a main body and, adjoining the main body and tapered relative to the main body, a mouthpiece with at least one suction opening. The teat has a first connector element for connection to the receiving unit, a second connector element for connection to the receiving unit, and a suction channel. The suction channel extends within the mouthpiece, extends and opens via a first end into the suction opening and is directed via a second end towards the main body. This second end forms the first connector element for leaktight connection to the receiving unit. The main body is designed such that it is adapted to be turned back towards the suction opening of the mouthpiece. This teat is adapted to be connected to the feeding bottle in a simple and hygienic manner and is easy to clean.Type: GrantFiled: June 10, 2009Date of Patent: December 20, 2011Assignee: Medela Holding AGInventors: Erich Pfenniger, Peter Vischer, Mario Rigert
