Abstract:
A breast pump apparatus, including a vacuum pump and a variable-volume buffer volume coupled together in fluid communication, also includes a breast-receiving portion coupled to the vacuum pump and the buffer volume such that the vacuum pump is operable to generate negative pressure at the breast-receiving portion to stimulate milk expression, and the negative pressure generated at the breast-receiving portion can be controlled by controlling the buffer volume.
