摘要： 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.

摘要： A system for monitoring upstream flow characteristics for a pump is provided. The system may receive one or more outputs from a fluid level sensor coupled with a pump. The system may detect based on at least the one or more outputs, an abnormal upstream flow condition in the pump, such as a full upstream occlusion in the tube, a partial upstream occlusion in the tube, an empty reservoir, and/or a backflow of the fluid into the drip chamber. The system may adjust, based on the detection of an abnormal upstream flow condition in the pump, operation of the pump.

摘要： A device including: a tubing clamp having a clamping mechanism holding closed a first fluid line while a second fluid flows along a second fluid line from a second container, the first fluid line delivers a flow of a first fluid; and a vacuum activated catch retainably coupled with the tubing clamp and coupled with the second fluid line, the vacuum activated catch including: a movable element coupled with the tubing clamp and configured for changing from a first shape to a second shape upon receipt of a deforming pressure, wherein when the movable element is in the first shape, the vacuum activated catch retains the tubing clamp in a closed position, and when the movable element is in the second shape, the vacuum activated catch releases the tubing clamp into an open position, thereby allowing the flow of the first fluid to commence within the first fluid line.
