ABSTRACT:
A breast pump that gently milks a lactating mother's breast is comprised of a housing having a flexible sleeve that receives the breast. A rotating wheel and connection rod combine to reciprocate the sleeve back and fourth relative to an opening on the housing while a cam operates to squeeze and unsqueeze the sleeve. A motor operatively connects to the cam and to the wheel. An adjustment mechanism adjusts the initial parameters of the sleeve in order to accommodate various sized breasts.
