Abstract
A breast shield for expressing human breast milk. The breast shield includes an outer housing and a flexible inner liner within the outer housing. In use, with the breast shield applied to a breast, the inner liner is in contact with the surface of both the areola and nipple of the breast. The breast shield further includes an outer chamber between the outer housing and the inner liner and an inner chamber within the inner liner. In use, the inner and outer chambers, are subjectable to differential pressure and the differential pressure is operable to cause the inner liner to exert a massaging effect against the surface of both the areola and nipple of a breast.
