Abstract
A breast pump including a vacuum pump, vacuum hose, collection container, and a milk pumping flange for application to a woman'"'"'s breast for removing milk from the breast, all included within a small carrying case when not in use. The flange includes flexible mouth and throat portions and is generally conical with an elliptical cross section and an interior shape including raised portions simulating the tongue and jaw of a baby. The flange attaches sealingly to a collection container such as a nursing bottle, and vacuum created within the bottle by the pump and hose is applied through the flange to the woman'"'"'s breast, while a vent opening controls application and release of vacuum. During use the woman can massage her breast through the flexible flange and can control the rhythm with which suction is applied and relaxed, to pump milk more quickly.
