Apparatus for infusing fluid
A pump for pumping fluid includes a tube platen, a plunger, a bias member, inlet and outlet valves, an actuator mechanism, a position sensor, and a processor. The plunger is configured for actuation toward and away from the infusion-tube when the tube platen is disposed opposite to the plunger. The tube platen can hold an intravenous infusion tube. The bias member is configured to urge the plunger toward the tube platen.
DETECTION ASSEMBLIES FOR INFUSION PUMPS
Embodiments disclosed herein relate to detection systems for an infusion pump. An occlusion detector for an infusion pump includes a membrane that deforms in response to fluid pressure in a fluid flow path branching off of the main fluid flow path of the infusion pump. The membrane deforms in response to fluid pressure, applying an axial pressure to a piston, which in turn triggers a force sensor. A controller of the infusion pump triggers an alarm or alerts a user when a threshold is reached. A bubble detector for the infusion pump includes a light emitter and reflective surface. Light shines through the fluid flow path, refracting differently if there is air present in the flow path. A light sensor detects the light and conveys an output signal to the controller. If detected air surpasses a threshold, the controller sounds an alarm or otherwise alerts the user.
Method for processing infusion data and an infusion pump system
A distributed infusion pump system is provided with long-term recording of the type of medication, nutrition or hydration, pump output pressure, corresponding infusion flow, infusion flow resistance, and an automatic or manual alarm in the event that thresholds applied to these parameters or their derivatives are exceeded.
Occlusion detection for infusion pumps
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.

Fluid line occlusion detection system and methods
The systems, methods and articles described herein are directed to at least one pressure sensor along a downstream fluid line which senses fluid pressure and assists an occlusion detection feature in determining the presence of occlusions in the downstream fluid line. In addition, the system can dynamically adapt the occlusion detection feature based on a delivery of fluid, such as a bolus, in order to prevent the system from creating a false alarm regarding an occlusion of the downstream fluid line.
