Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for detecting an occlusion in an infusion pump system, the method comprising: delivering fluid through a flow path, the flow path being in fluid communication with a flexible membrane such that pressure within the flow path above a threshold pressure causes the flexible membrane to expand, wherein the flexible membrane is positioned adjacent a light transmissive member such that the expansion of the flexible membrane results in the pressing of the f…
