Abstract
A pump device includes a pump driver comprising a first diaphragm and a second diaphragm, the first and second diaphragms each comprising a middle portion bounded by an outer portion, the first and second diaphragms being spatially separated from each other at the respective outer portions, and coupled together at the respective middle portions. The pump also includes a fluid passageway and a pump chamber fluidly connected to the fluid passageway, wherein the pump chamber comprises a moveable wall coupled to the pump driver at the middle portions of the first and second diaphragms such that a fluid movement between the pump chamber and the fluid passageway is induced by movement of the middle portions. An input device is configured to obtain a target flow rate. A controller is configured to operate the pump driver and a flow regulator based on signals received from a flow detector.
