Silent pumping mechanism for infusion pump

Abstract

Features relating to a pumping mechanism of a peristaltic infusion pump are provided. Stabilizing protrusions are provided for one or more pumping fingers of the pumping mechanism, where the one or more pumping fingers move in a coordinated and synchronized fashion with respect to one another to provide a controlled peristaltic action against a flexible tube for delivery of a fluid to a patient. The protrusions extend outward from one or more side regions of the pumping fingers to create points of contact on a side-wall of a recess in a chassis in which the pumping mechanism is positioned. The points of contact serve to stabilize the fingers to prevent vibration and/or movement of the fingers against the sidewall.
