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 that defines a structure that fits substantially within a user's bra;
a conduit;
a pumping structure configured within the main body, the pumping structure including a pump mechanism; and
a milk collection container configured within the main body of the breast pump system and including a one-way valve, the milk collection container comprising a generally ring shape, the one-way valve configured to connect to the conduit and the milk collection container is immediately sealed when detached from the conduit, the milk collection container configured about the pumping structure;
wherein the pump mechanism is configured to pump milk from a breast through the conduit to the milk collection container.
2. The wearable, portable self-powered breast pump system of claim 1 , wherein as the pump mechanism operates the conduit becomes mostly filled with milk, the breast pump system thereby approaching a fully hydraulic system.
3. The wearable, portable self-powered breast pump system of claim 2 , wherein the milk pumped from the breast is employed as hydraulic fluid.
4. The wearable, portable self-powered breast pump system of claim 1 , wherein the one-way valve is integral with the milk collection container.
5. 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.
6. The wearable, portable self-powered breast pump system of claim 1 , wherein a latch suction is maintained throughout a pumping session.
7. 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.
8. 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.
9. The wearable, portable self-powered breast pump system of claim 1 , further comprising a controller that controls pumping to provide a desired waveform.
