- Many actuation mechanisms known to those of skill in the art can be utilized for the
actuatable assembly 205.Actuatable assembly 205 can be a piston assembly, a pump such as a diaphragm pump, or any other suitable actuation mechanism. The optimal configuration foractuatable assembly 205 can depend on a number of factors, such as: vacuum requirements; size, power, and other needs of thepumping device 200; and the properties of the fluid 230, such as viscosity, biocompatibility, and fluid life requirements. -
FIG. 3 illustrates an exemplary embodiment in whichactuatable assembly 205 is a piston assembly and drivingelement 215 is a piston.Actuatable assembly 205 includesradial seals 220, such as O-rings, sealing againstassembly housing 210 to prevent undesired egress offluid 230 and to enable driving offluid 230. -

Preferably,actuatable assembly 350 is releasably coupled to apendant unit 360 and the driving mechanism housed therein. The coupling can be a mechanical coupling or any suitable quick release mechanism known to those of skill in the art. The releasably coupled design allows for flexibility in the configuration and use of the pumping device. For instance, user comfort can be improved through the use of differently sized breast interfaces for compatibility with various breast sizes.

FIGS. 8A and 8B illustrate preferred embodiments of abreast interface 400 in which anexit valve 405 is integrated into theflexible membrane 410 to control the flow of expressed milk throughexit port 415.
