Publication number: 20180028732Abstract: A breast pump for pumping human breast milk has a flexible pumping membrane and a stiff cap, which can be fitted onto said pumping membrane, this resulting in the formation of a pumping chamber for generating a negative pressure. The cap can be, or is, connected to a breast-shield unit via a suction line. The pumping membrane has an encircling collar with a step and a laterally projecting protrusion. The cap has, on its inner side, an encircling abutment region and also at least one form-fitting element, which is spaced apart from the encircling abutment region and establishes a form fit with the protrusion of the pumping membrane. The cap is positioned with a snap fit on the pumping membrane. In the abutment region (53), it establishes a joint frictional fit with a step of the pumping membrane and thus forms a seal. The snap-fit positioning of the cap on the pumping membrane is sufficient for the cap to be retained with sealing action on the pumping membrane.Type: ApplicationFiled: February 9, 2016Publication date: February 1, 2018Inventors: Mario Rigert, René Fischer

Publication number: 20170043073Abstract: A mechanical fluid pressure modification valve, or “MFLP-valve”, is set forth. The MFLP-valve can be actuated upon movement of a movable pressure system member of a medical pressure system reaching a selected position. Additionally, the MFLP-valve can be actuated based on a pressure condition of the system. When the MFLP-valve unseals, a pressure differential between a pressure chamber and a volume outside of the chamber can be relieved. Disengagement of the movable pressure system member from the MFLP-valve can enable the MFLP-valve to re-seal. The MFLP-valve may include a flag that indicates the position of the movable pressure system member. The MFLP-valve may be provided in a diaphragm-type pressure source.Type: ApplicationFiled: August 12, 2016Publication date: February 16, 2017Inventors: Jahi Gist, David Cho, Mario Rigert
