Abstract
The breast shield with suckling motion one-way valve of the present invention is a breast shield for use with a breast pump wherein the breast shield has a one-way valve configured to mimic the suckling action/motion of a nursing infant which can optionally be located beneath a plurality of holes to drain expressed milk. The breast shield of the present invention is used to improve the breast pumping experience, it can be used from any body position from sitting upright to laying fully recumbent, and it reduces or eliminates back flow of expressed milk.
