A breast milk collection device includes a reservoir volume and an adaptor having one end to receive a woman's breast. The adaptor has a drip tube communicating with the reservoir. A source of cyclical application and relief of vacuum force is applied to the woman's breast located in the adaptor for the expression of breast milk. A one-way assembly permits breast milk to enter the reservoir and to submerge the valve element. The valve assembly includes a flexible barrier having an interior hollow chamber in fluid communication with said cyclical source of vacuum force and relief pressure, the flexible barrier fluidly isolating the source from the reservoir. The flexible barrier inflatably expands when relief pressure is applied to the interior of the flexible barrier, the flexible barrier becoming deflated when a vacuum force is applied to the hollow interior of the flexible barrier.

A system and method configured to separate PFAS from expressed breast milk, thereby producing breast milk which is essentially free (or at least contains a lesser amount of) per- and polyfluorinated substances, the system and method including filtration device including an adapter configured to be at least one of positioned in-line in a breast pump or between breast milk containers, and including a replaceable cyclodextrin based filter for filtration of PFAS from pumped breast milk.

The combination of a breast pump shield, with its ring, applied to the flange lower end of the shield, and the ring being C shaped in cross-section, having an upper flange, a lower flange, both integrally structured with a base wall. The physiological stimulator integrally formed with the lower flange of the sealing ring extends inwardly and upwardly within the shield, and therein functions as a means to place pressure upon the breast of the mother to help induce and stimulate the flow of breast milk during usage of the associated breast pump.
