Zusammenfassung:	Peristaltic pumps are described herein. In certain embodiments, a peristaltic pump includes a plunger, a first biasing member, and a second biasing member. The plunger is movable to selectively engage a pumping volume of a tubing segment to expand the pumping volume to draw fluid flow into the pumping volume and to contract the pumping volume to conduct fluid flow from the pumping volume. The first biasing member is configured to urge the plunger toward the tubing segment to maintain contact with the tubing segment during the expansion of the pumping volume. The second biasing member is configured to urge the plunger toward the tubing segment to contract the pumping volume.
