Patent number: 10744243Abstract: 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: GrantFiled: February 9, 2016Date of Patent: August 18, 2020Assignee: MEDELA HOLDING AGInventors: Mario Rigert, René Fischer

Patent number: 10493189Abstract: 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: GrantFiled: August 12, 2016Date of Patent: December 3, 2019Assignee: MEDELA HOLDING AGInventors: Jahi Gist, David Cho, Mario Rigert

Patent number: 10493188Abstract: The present invention provides a breastshield for use in a breastpumping system for expressing milk, the breastshield being of such a construction that substantially limits the amount of air between the breast/nipple and the breastshield surrounding the breast/nipple, and most preferably virtually eliminates any air at least in the area of the breast and nipple. In some embodiments, any air in the breastpumping system is substantially eliminated. With the amount of air limited, the mechanism used for generating the pressure difference in the breastshield (e.g., vacuum or negative pressure), such as a diaphragm pump, does not need to do as much work. Less energy is required for the expression of milk, and thus the size of pump used can be decreased, thereby reducing the overall cost of the device.Type: GrantFiled: November 9, 2017Date of Patent: December 3, 2019Assignee: MEDELA HOLDING AGInventors: Brian H. Silver, Samuel B. Levey, Carr Lane Quackenbush, Beda Weber, Etienne Furrer, Daniela Wackerlin
