Abstract
A motorized pump is disclosed that includes a flexible diaphragm fitting within a rigid member, a motor drive mechanism for drawing a puller member (48) attached to the diaphragm (70) away from the rigid member to create a space between the diaphragm and the rigid member and form a negative pressure region within that space, and an outlet communicating with the negative pressure region. In one embodiment, the pump provides a negative pressure source for a breast pump that is readily portable by virtue of the soft carrying case within which the diaphragm pump and motor are housed.
