Abstract
A fluid pump device includes an elastically deformable conduit, multiple volume displacement elements, and a controller. During operation, the controller controls movement of the multiple volume displacement elements (such as compensation volume displacement elements and occluding volume displacement elements) with respect to the elastically deformable conduit at different times to cause flow of fluid in the elastically deformable conduit downstream to a recipient. The controller controls movement of the multiple volume displacement elements to volumetrically balance: i) an input flow rate of input fluid conveyed from a fluid source downstream to an input of the elastically deformable conduit, and ii) an output flow rate of output fluid delivered from an output of the elastically deformable conduit downstream to a recipient.
