Abstract
A breast pump provides multiple orientations of the pumping lever with respect to the breast shield. A breast pump includes a liner extending from the breast shield, through the suction chamber, and out of the suction chamber, which liner shields other components of the pump from contamination by the flow of milk through the pump during pumping operation. A breast pumping device includes a pumping lever for manually providing a cyclical vacuum within the suction chamber and an external pumping source, connected to the suction bell, that the user can activate to provide a cyclical vacuum within the suction chamber. A breast pump provides a smaller change in the grip width from when the lever is fully-extended to when the lever is fully-retracted, allowing more comfortable manual pumping.
