Abstract
An infusion pumping mechanism includes a motor, a plurality of pump fingers and an opposing plate. Each finger of the pump fingers includes a body portion and a head portion. The head portion includes a tip that is configured to contact and occlude a tube installed in the pumping mechanism. The opposing plate includes an anvil with a plurality of force concentrators. A force concentrator of the plurality of force concentrators corresponds to a respective pump finger of the plurality of pump fingers. Additionally, the force concentrator includes a concentration surface configured to contact and occlude the tube. The force concentrator is aligned with a tip of the respective pump finger such that as the finger is directed towards the tube and contacts the tube, both the tip and the force concentrator provide pressure to opposite sides of the tube and at least partially occlude the tube.
