Abstract

A breast milk collection device, comprising an adaptor adapted at a first wide end to receive a woman's breast and a second narrow end of the adaptor communicating with a reservoir. The reservoir is adapted to receive breast milk from the adaptor. The second narrow end of the adaptor has a first aperture and a hollow drip tube in communication with the first aperture. The hollow drip tube has a second aperture through which the hollow drip tube communicates with an internal volume of the reservoir. A one-way valve element communicates with the hollow drip tube and with the internal volume of the reservoir. A flexible barrier is disposed across a hollow chamber formed in a rigid barrier housing, the flexible barrier creating a hermetic seal between the rigid barrier housing and the hollow chamber, and the hollow chamber fluidly communicating with an interior of the hollow drip tube. A drive assembly including a reciprocally driven member contacts a first surface of the flexible barrier to reciprocally drive the flexible barrier to a first position during a first position of the reciprocally driven member. The flexible barrier returns to a second position during a second position of the reciprocally driven member, providing an alternating source of vacuum pressure and relief of vacuum pressure in the hollow drip tube.
