Abstract
A breast pump insert formed of a soft, resilient and translucent polymer material, such as a silicon polymer, that is inert against boiling water has a monolithic self-supporting structure consisting of a first or funnel-shaped portion for contact with a nipple-encompassing breast area and for providing a deformable sealing connection between the nipple-encompassing area and the suction bell of the breast pump when the pressure is reduced therein; and of a second or thimble-shaped portion for maintaining an enclosure around the nipple-encompassing area when the pressure is reduced within the pump; the thimble-shaped portion of the insert has an elongated and essentially tubular longitudinal wall section and an essentially transverse end wall section that provides a helmet-shaped end of the structure and includes at least one perforation for permitting passage of milk; the timble-shaped portion is formed and dimensioned to prevent axial collapse thereof under normal use conditions.
