Breast pump system and methods
Systems and methods for pumping milk from a breast, wherein the milk is expressed from the breast under suction and milk is expulsed from the pumping mechanism to a collection container under positive pressure.
1. A wearable, portable self-powered breast pump system for pumping milk from a breast and sized to fit within a user's bra, comprising:
a main body;
a breast contacting portion;
a milk collection container;
a conduit having a first end that directly connects to the breast contacting portion and a second end that directly connects with the milk collection container; and
a pump mechanism including elements configured to compress and pull open the conduit, the pump mechanism configured to pump milk from the breast contacting portion through the conduit to the milk collection container, the pump mechanism configured such that the conduit becomes mostly filled with milk and the breast pump system approaches a fully hydraulic system;
wherein the conduit and pump mechanism are configured within the main body and wherein the milk collection container generally defines a ring shape.
2. The wearable, portable self-powered breast pump system of claim 1 , wherein the milk pumped from the breast is employed as hydraulic fluid.
3. The wearable, portable self-powered breast pump system of claim 1 , further comprising a breast adapter configured and dimensioned to form a seal with the breast.
4. The wearable, portable self-powered breast pump system of claim 1 , wherein a latch suction is maintained throughout a pumping session.
5. The wearable, portable self-powered breast pump system of claim 1 , wherein the milk collection container includes an integrated valve.
6. The wearable, portable self-powered breast pump system of claim 1 , wherein the milk collection container is sealed when detached from the conduit.
7. The wearable, portable self-powered breast pump system of claim 1 , wherein the milk collection container is a compliant bag, the compliant bag configured to be releasably connected to the breast pump system and to receive pumped milk.
8. The wearable, portable self-powered breast pump system of claim 1 , further comprising a controller that controls pumping to provide a desired waveform.
9. The wearable, portable self-powered breast pump system of claim 1 , further comprising a plurality of operational settings, wherein at least one operational setting is at least one suction level setting, a suction waveform definition, an extraction phase time, a threshold milk volume estimate per extraction phase, an expulsion pressure, a rest phase timing, a heating temperature, a heating time, a vibration frequency or a vibration time.
10. The wearable, portable self-powered breast pump system of claim 1 , wherein the milk collection container is configured within the main body, and the main body is sized to fit substantially within a user's bra.
