Patent number: 9717849Abstract: Some embodiments of an infusion pump system may include an occlusion sensor that can be used to detect when an occlusion exists in the fluid path between the medicine reservoir and the infusion site on the user's skin. Such an occlusion may occur, for example, when the fluid flow line (e.g., a cannula, infusion set tubing, or the like) is kinked. If the medicine dispensation path to the user is occluded, the user may receive no dosage or a lower dosage of the medicine. As such, the occlusion sensor can be used to indicate when the fluid is flowing or not flowing, thereby permitting the infusion pump system to communicate an alarm to the user if an occlusion exists.Type: GrantFiled: October 20, 2016Date of Patent: August 1, 2017Assignee: Bigfoot Biomedical, Inc.Inventors: Amit Mhatre, Jian Yao Wu, Mitchell Wenger, Steven A.
