Abstract
Systems and methods for detecting an occlusion in a fluid delivery device are disclosed. The system includes a fluid delivery tube, an occlusion detection sensor configured to be coupled to the fluid delivery tube and further configured to detect occlusion within the fluid delivery tube. The fluid delivery tube includes an occlusion detection portion. The occlusion detection sensor is further configured to detect alteration of a shape of the occlusion detection portion when at least one condition occurs within the fluid delivery tube.
