Abstract
An infusion pump, driven by a camshaft with one or two cams, controls two sets of angularly aligned fingers phased within a sleeve, compressing two parallel flexible tube-sections, drawing fluid from a fluid source, yielding a combined continuous flow of fluid output from the two tube-sections as a function of the camshaft rotation.
