Disclosed is a low cost, disposable, infusion pump. The infusion pump can include an integrated occlusion detector that detects both upstream and downstream occlusions in an infusion tube. In addition, the infusion pump can easily monitor flow rates through the infusion tube, and be quickly set to infuse at a pre-determined rate. An armature within the infusion pump works in concert with a pair of tubing pinchers to precisely control the movement of fluid within the tubing. Sensors mounted within the device detect the position of the armature and can determine if an occlusion has occurred in the tubing.
