Abstract
A flexible resilient breast pump insert adapted to fit onto a vacuum generating breast pump operable to cyclically generate and release a negative pressure is disclosed. The insert has deformable zones ( ) spaced from each other along the longitudinal axis of the insert which are connected to the source of negative pressure so that the zones ( ) are deformed sequentially when the negative pressure is applied, to cause them to move inwardly and outwardly relative to the users nipple and areola and apply a peristaltic pressure thereto.
