Abstract: The invention relates to a teat for feeding bottles, including a receiving head, produced from a dimensionally stable material, and a rubber-elastic suction element. An entry channel leads to the bottle interior and channels lead from there to the outer surface of the receiving head. The suction element, in an initial position, elastically and sealingly rests on at least one section of an outer surface of the receiving head. Milk ducts are located in the contact area between the suction element and the receiving head and communicate with the channels of the receiving head which lead towards the outlet channel in the mouthpiece so that, when a vacuum is produced in the mouthpiece, milk can flow from the feeding bottle through the milk ducts to the outlet channel, the suction element being returnable to its initial position and the flow of milk being interrupted when there is no vacuum.

Abstract: The invention relates to an assembly with a filter housing and at least one filter cartridge. The at least one filter cartridge is tubular, has a tube wall provided with a filter and comprises a central discharge channel with a discharge connection for discharge of filtered medium. The tube wall has a filter through which the medium to be filtered is able to flow transversely to the tube wall. The filter housing has a filter chamber, surrounded by a side wall, in which the at least one filter cartridge is accommodated with the longitudinal direction parallel to the side wall. The invention furthermore is directed to a filter cartridge intended for such an assembly.

Abstract: Systems for supplying emergency oxygen or other gases to persons are addressed. The systems may include pod assemblies mounted on fixed-position masts between or adjacent passenger seats or pop-up modules installed within upper portions of seat backs. The pod assemblies and pop-up modules additionally may include other passenger-service equipment. Also optionally included in the systems are modular central gas supplies and alternative oxygen mask designs for passengers.

Abstract: Module assembly for a gas system operating at pressures greater than 100 bar. The assembly comprises at least two modules made as solid metal blocks. Bach block provided with a system of drilled channels and appendages. The system of channels comprises a main and at least one branch channel. The appendages comprise at least a shut-off valve and a flow or pressure meter connected to the branch channel. The blocks of two modules are positioned laterally against one another. Each block having openings aligned with a corresponding number of openings in the other block, for joining channels in the one block to channels in the other block. The invention furthermore relates to a gas system provided with the module assembly according to the invention and to the use of such an assembly.

Abstract: A breastpump is provided which is programmable for different suction sequences, and which records a pumping sequence or an entire session of varying sequences for later retrieval and playback in operation of the breastpump.

Abstract: The suction pump is essentially comprised of three separate pump parts, namely of a drive unit located inside a main casing (1), of a collecting reservoir (8) and of a valve block (6), which is arranged directly between the casing (1) and reservoir, whereby these parts can be easily coupled to one another in a manner that enables them to be detached.

Abstract: The diaphragm suction pump has a pump chamber (7) located in a base plate (6), the wall of said chamber extending in a conical manner from a central flat base section (7?) to the lateral edge (8). The elastic pump diaphragm (5), which spans the pump chamber (7), is configured in such a way that it lies tightly against the entire pump chamber wall at the top dead center point of the drive connecting rod (4). The diaphragm (5) consists of a self-supporting elastic material with rear recesses (9; 10), which form hinges that can be elastically pretensioned during the operation of the diaphragm (5).

Abstract: Breastpumps and methods for use in extracting breastmilk, which can be used to generate, among other things, both a letdown or stimulation phase and a milk expression phase, are disclosed.

Abstract: The invention relates to a breast pump, which in addition to a drive motor (7), vacuum diaphragm pump (1) and programme-controlled electronics (4), comprises a vacuum chamber (12) with a separation diaphragm (13), which is connected between a pump intake conduit (9) and an extraction hood (11). The first chamber (14) is equipped with a device (16) for the negative or positive aeration of said chamber. Said device (16) is also programme-controlled by the electronics (4) during the normal continuous operation of the pump (1).
