  • Patent number: 8535264
    Abstract: A device for expressing milk, with a vacuum-generating unit, which includes a drive motor and a vacuum-generating device, with a switching unit, which is linked to the vacuum-generating unit and determines the suction cycles via a rotatably driven switching member, and with at least one milk expression attachment, which is or can be brought into flow communication therewith and which includes a suction funnel that can be placed on the breast, and a milk collection receptacle. A compact design with reliable function is achieved by the switching member being coupled to the drive motor of the vacuum-generating unit via a transmission for the rotary drive.

  • Patent number: 7267662
    Abstract: A milk sucking pump having a top component with a breast joining piece and which is or can be detachably fixed to the opening of a container and a hand pump unit that is detachably connected thereto by a connecting branch or a connecting bore. The hand pump unit has a cap-like connection section and a pump piston which can be moved to and from in a piston-swept volume by a rotatable actuating handle that has a return mechanism. This invention provides a simple construction and good handling. The cap-like connection section and the piston-swept volume are combined to form a uniform cap component which is fixed to the top component. The return mechanism acts upon the actuating lever and is mounted on the cap component.
