Breast pump system with controller

A wearable, portable self-powered breast pump system shaped to fit within a bra, the breast pump system comprising:

• a housing, the housing including a receptacle formed therein;
• a breast adapter configured to contact and form a seal with a breast, the breast adapter including a nipple receiving portion formed integrally therewith, and a bottom portion below the nipple receiving portion, the breast adapter sized and shaped to be received within the receptacle;
• a pump contained within the housing, the pump positioned above the nipple receiving portion;
• a milk collection container defined by walls that are separate and distinct from the breast adapter and configured to contact the breast, the milk collection container being transparent and including graduation markers;
• an indicator light;
• a controller contained within the housing that changes application of a suction force on the breast through the nipple receiving portion by the pump from a letdown phase to an expression mode;
• and
• a battery electrically connected to the controller;
• wherein the pump is associated with the nipple receiving portion and the pump creates the suction force in the nipple receiving portion, the suction force and at least a portion of a pumped milk being directed generally upward relative to the bottom portion of the breast adapter;
• wherein the receptacle is positioned below a center of the housing so that the breast pump system rides in a higher position relative to the breast.
