Wearable breast pump system

A breast pump system, comprising:

• a control unit configured to generate negative air pressure;
• and
• a wearable milk collection hub configured to be connected to the control unit by an air tube, the wearable milk collection hub comprises:
• a transparent breast shield comprising a breast flange and a nipple tunnel;
• a transparent outer shell configured to be removably attached to the breast shield to form an interior volume for collecting expressed milk;
• a diaphragm configured to be arranged concentric with the nipple tunnel and configured to be removably attached to the outer shell;
• and
• a diaphragm cap configured to be removably attached to a front surface of the outer shell to cover and seal the diaphragm, the diaphragm cap comprising an air port configured to receive the air tube.

A wearable milk collection hub, comprising:

• a breast shield comprising a breast flange and a nipple tunnel;
• a diaphragm configured to deform to create negative air pressure in the nipple tunnel;
• an outer shell configured to be removably attached to the breast shield to form a vessel for collecting expressed milk, the outer shell comprising:
• a rear end comprising an edge configured to seal with the breast shield;
• a front end opposite the rear end;
• a curved surface curving from the edge of the rear end to the front end;
• and
• a milk pouring opening located toward the top of the outer shell;
• and
• a diaphragm cap configured to be removably attached to the front end of the outer shell to seal the diaphragm, the diaphragm cap comprising an air port configured to receive an air tube.

A wearable milk collection hub, comprising:

• a breast shield comprising a breast flange and a nipple tunnel;
• an outer shell configured to be removably attached to the breast shield to form a vessel for collecting expressed milk;
• a diaphragm configured to deform from a relaxed state to create negative air pressure in the nipple tunnel;
• a milk port configured so that the expressed milk flows into the vessel through the milk port;
• and
• a non-return valve configured to be mounted to the milk port and to pass the expressed milk in one direction,
• wherein when the diaphragm is in the relaxed state, at least a portion of the diaphragm extends over the lies adjacent to the milk port.

A breast pump system, comprising:

• a control unit configured to generate negative air pressure;
• a wearable milk collection hub configured to be connected to the control unit, the wearable milk collection hub comprising:
• a breast shield;
• an outer shell configured to be removably attached to the breast shield to form a vessel for collecting expressed milk;
• a non-return valve configured to pass the expressed milk in one direction into the vessel;
• a diaphragm;
• and
• a diaphragm cap configured to seal the diaphragm, the diaphragm cap comprising a flat portion configured to allow the wearable milk collection hub rest on a flat surface with the breast shield facing uppermost;
• and
• an air tube connection assembly, comprising:
• a tube splitter;
• a first tube configured to connect to the control unit;
• a second tube configured to connect to the wearable milk collection hub;
• and
• a third tube.
