Abstract
A manual breastpump has a pump mechanism for use in one mode of operation to produce an ejection (letdown) reflex in a nursing mother and in a separate mode of operation for the general expression of breastmilk. The breastpump further provides a pump mechanism having an expansible chamber device carried by the handle, which is operated by moving the handle relative to a handle mount. A double-pivot for the handle yields letdown mode as well as the general pumping mode.
