METHODS AND APPARATUS FOR TRANSFERRING PRESSURE DURING EXPRESSION OF HUMAN BREAST MILK

摘要

A device for expression and collection of breast milk includes an actuatable assembly and a breast interface. The breast interface is sized to receive a breast and form a fluid tight seal against the breast. The breast interface includes an expandable membrane disposed within at least a portion of the breast interface. The expandable membrane reversibly deforms in response to actuation of the actuatable assembly, thereby applying vacuum pressure at the breast to express milk. The expandable membrane comprises a plurality of expandable pleats which extend radially outward from a central longitudinal axis of the breast interface.

1. A device for expression of milk from a breast, said device comprising:
an actuatable assembly; and a breast interface sized to engage a breast and fluidly seal thereagainst, the breast interface having an expandable membrane disposed within at least a portion thereof, wherein the expandable membrane moves in response to actuation of the actuatable assembly thereby applying vacuum pressure at the breast to express milk therefrom; wherein the expandable membrane comprises a plurality of expandable pleats, each of the plurality of expandable pleats extending radially outward from a center of the expandable membrane.
