A system including a tube and a force sensor coupled to a wall of the tube via a restraining element and configured to obtain a value of a tubing force when the tube is deformed by the restraining element. The system includes a processor to determine parameters for fitting a curve including the value of the tubing force, to determine a fluid pressure value for a fluid in the tube based on the parameters for fitting the curve, and to activate an alarm responsive to the fluid pressure value and to the parameters for fitting the curve when an occlusion condition is identified in the tube. The parameters for fitting the curve comprise at least one time-decaying parameter(s) associated to the tubing force. A method for using the system and a non-transitory computer readable medium including instructions to perform the above method are also provided.

Occlusion detection for infusion pumps

A syringe pump can be operated to produce fluid flow from a syringe installed therein. Features of the pump can produce a desired rapid commencement of flow followed by smooth delivery uninterrupted by stiction-induced slowing and acceleration. A stiff drivetrain can facilitate detection of excessive forces indicative of friction at a stopper-wall interface. The motor drive, gearing, and control parameters can enable customized acceleration patterns to determine optimal initial stage advancement to provide fluid delivery. These patterns can minimize or eliminate the delay in commencement of flow by overcoming both mechanical slack remaining and syringe stopper slack. To avoid flow irregularities produced by stiction forces in the stopper further, a mechanical vibration can be provided to the syringe and/or barrel to introduce movement of the stopper-wall interface, reducing the creation of high static friction coefficients.
