Abstract: A syringe imaging system for a syringe infusion pump is provided. The system comprises an imaging device configured to capture one or more images of a syringe, and a processor, which is configured to determine, based on the one or more captured images, an internal diameter of the syringe and a distance between a bung and a bottom of the syringe, and to calculate a remaining volume of the syringe based upon the determined internal diameter and distance. A syringe infusion pump is also provided. The pump comprises a housing having a bracket configured to receive a syringe, a syringe driver configured to actuate a plunger of the syringe, an imaging device configured to capture one or more images of the syringe, and a processor. The processor is configured to determine, based on the one or more captured images, an internal diameter of the syringe and a distance between a bung and a bottom of the syringe, and to calculate a remaining volume of the syringe based upon the determined internal diameter and distance.

Abstract: A force sensor assembly for use in peristaltic pumps includes a housing and a load cell at least partially disposed within the housing. A plunger, pivotable about an axis, has an upper surface and an underside surface distal from the upper surface. The underside surface cooperates with the load cell. The force sensor further includes a mechanism to reduce the load cell's sensitivity to the positioning of an applied force on the upper surface.
