A device for expression and collection of breast milk includes an actuatable assembly, a breast interface, and a tube. The breast interface is sized to receive a breast and form a fluid tight seal against the breast. The breast interface includes a deformable member disposed within at least a portion of the breast interface. The deformable member deforms in response to actuation of the actuatable assembly and applies vacuum pressure against the breast to express milk. The tube operatively couples the actuatable assembly to the breast interface.

1. A device for expression and collection of breast milk, said device comprising: an actuatable assembly;a breast interface configured to engage a breast and fluidly seal thereagainst, the breast interface comprising a housing and a single, continuous membrane disposed within and coupled to the housing to form a continuous reservoir therebetween, the reservoir comprising a sole negative pressure source for the breast interface, the reservoir extending between the housing and the membrane and filled with an incompressible liquid so as to be fluidly separated from the breast milk expressed from the breast, wherein the membrane is shaped to form a first opening configured to receive at least a nipple of the breast therethrough; anda tube operatively coupling the actuatable assembly to the breast interface,wherein the actuatable assembly, when actuated, is configured to affect movement of at least a portion of the liquid out of the reservoir, andwherein the membrane is configured to move away from the nipple in response to movement of the liquid out of the reservoir, thereby generating sufficient negative pressure with the sole negative pressure source at the breast interface to cause expression of the breast milk from the breast. 2. The device of claim 1, wherein the actuatable assembly comprises a piston or a pump. 3. The device of claim 1, wherein the tube is filled with the liquid, and wherein the actuatable assembly is configured to displace the liquid disposed in the tube when actuated. 4. The device of claim 1, wherein the membrane is flexible. 5. The device of claim 1, wherein the membrane is configured to move circumferentially about the nipple in response to movement of the liquid out of the reservoir. 6. The device of claim 1, wherein the membrane comprises a deformable portion. 7. The device of claim 1, wherein the reservoir is configured to be disposed circumferentially about the nipple. 8. The device of claim 1, further comprising an electromechanical driving mechanism operatively coupled with the actuatable assembly, and configured to actuate the actuatable assembly. 9. The device of claim 1, wherein the membrane is further shaped to form a second opening to allow the breast milk to exit the breast interface therethrough, the second opening smaller than the first opening. 10. The device of claim 9, wherein first opening is directed laterally to receive the breast therethrough, and wherein the second opening is directed downwards to allow the breast milk to drain therethrough by gravity. 11. The device of claim 1, wherein the breast interface comprises an exit valve, the exit valve configured to control flow of the expressed breast milk out of the breast interface into a collection vessel. 12. The device of claim 11, wherein the membrane is shaped to form the exit valve. 13. The device of claim 1, further comprising a controller for controlling actuation of the actuatable assembly, controlling calculation and display of breast milk production information, or controlling communication with other devices. 14. The device of claim 1, further comprising a sensor adjacent the breast interface, the sensor configured to sense at least one aspect of milk flowing therepast. 15. A method of expressing and collecting breast milk, said method comprising: providing a breast expression and collection device having a breast interface and an actuatable assembly operatively coupled thereto, wherein the breast interface comprises a single, continuous membrane disposed within and coupled to a housing to form a continuous reservoir therebetween, the reservoir comprising a sole negative pressure source for the breast interface;engaging and fluidly sealing a breast with the breast interface such that at least a nipple of the breast is received through a first opening of the membrane;actuating the actuatable assembly;moving at least a portion of an incompressible liquid disposed within the reservoir out of the reservoir in response to actuation of the actuatable assembly;moving the membrane away from the nipple in response to movement of the liquid out of the reservoir, thereby creating and applying sufficient negative pressure with the sole negative pressure source at the breast interface to cause expression of the breast milk from the breast; andexpressing and collecting the breast milk from the breast. 16. The method of claim 15, wherein actuating the actuatable assembly displaces the liquid disposed within a tube that operatively couples the actuatable assembly and the breast interface, thereby moving the liquid out of the reservoir. 17. The method of claim 15, wherein moving the membrane away from the nipple comprises moving the membrane circumferentially about the nipple. 18. The method of claim 15, wherein actuating the actuatable assembly comprises moving a piston. 19. The method of claim 15, further comprising sensing at least one aspect of the expressed breast milk with a sensor fluidly coupled with the breast interface.
