Occlusion detection for infusion pumps

Abstract

An infusion pump for detection of a fluid condition in a flexible tubing is provided. The infusion pump includes a sensor positioned to obtain a value of a tubing force when the tube is received by the infusion pump, a memory storing instructions and a processor. The processor is configured to execute the instructions to generate a force-time curve representative of values of the tubing force obtained by the sensor over time, determine a time-decaying parameter associated with the tubing force characterizing the force-time curve, and determine a fluid pressure value for a fluid in the tube based at least in part on the time-decaying parameter, a material of the tube, a dimension of the tube, and a use history of the tube. A method for using an infusion pump is also provided.
