Abstract
A breast milk collection apparatus includes a milk collection bottle, a breast shield, and a suction transfer assembly for mounting on the bottle. The suction transfer assembly includes a housing for connecting to the vacuum pump and the breast shield. Included in the suction transfer housing is a reversible diaphragm made of a deformable elastomeric material configured with a spiral undulatory configuration. The breast shield includes a unitary funnel member from a relatively rigid polymer as well as an annular deformable lip for enhanced comfort. In one preferred construction, a pump enclosure defines a well for receiving a bottle with deformable gripping projections which adapt to changes in bottle size.
