Abstract
A breastmilk collection device includes breast contacting flange, a vacuum reservoir, flexible diaphragm separating the breast contacting flange and the vacuum reservoir, and a flange receiver between the breast contacting flange and the flexible diaphragm. The breast contacting flange has a wide portion for accepting the breast and a narrow portion. The flexible diaphragm is located between the narrow portion and the vacuum reservoir. The flexible diaphragm moves between a sealed configuration, in which the breast contacting flange is sealed off from the vacuum reservoir, and an open valve configuration, in which the flexible diaphragm acts as a one-way valve to allow expressed milk to flow through a milk flow opening between the flexible diaphragm and the breast contacting flange when an opening pressure is reached in the breast contacting flange.
