Abstract: 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.

Abstract: A pump for pumping fluid, the pump comprising a tube platen; a plunger configured for actuation toward and away from the tube platen when the tube platen is disposed opposite to the plunger; a bias member configured to urge the plunger toward the tube platen; an inlet 5 valve upstream of the plunger configured for actuation between an occluding position and a non-occluding position; an outlet valve downstream of the plunger configured for actuation between an occluding position and a non-occluding position; an actuator mechanism configured to control the actuation of the plunger, the inlet valve and the outlet valve, wherein the actuator mechanism is configured to mechanically engage and disengage from 10 the plunger, wherein when the actuator mechanism is disengaged from the plunger, the actuator mechanism is configured to mechanically discharge the bias member such that the plunger is a sole force driving the plunger toward the tube platen, wherein the actuator mechanism is configured to engage the plunger to lift the plunger away from the tube platen to thereby mechanically charge the bias member; a pressure sensor disposed adjacent to at 15 least one of the inlet valve, the outlet valve, and the plunger; a position sensor configured to estimate a position of the plunger; and a processor coupled to the position sensor to receive the estimated position of the plunger therefrom. The processor is configured to detect an anomaly based in part on the estimated plunger position when: the inlet valve is in the occluding position, the outlet valve is in the occluding position, the actuator mechanism is 20 mechanically disengaged from the plunger thereby making the bias member the sole source of actuation force of the plunger toward the tube platen, and the bias member urges the plunger toward the tube platen. The processor is further coupled to the pressure sensor to receive a pressure signal from the pressure sensor, the processor is configured to, using the pressure signal, to determine a downstream occlusion exists if a subtraction of a filtered 25 value of a sequential series of sequential trough-to-trough pressure values of a plurality of cycles from a trough-to-trough value is greater than a predetermined threshold.

Abstract: A method for discharging fluid from a syringe and for mitigating occlusion conditions includes actuating the plunger of a syringe into a barrel. The method monitors fluid pressure within the barrel of the syringe and determines that an occlusion exists when the fluid pressure exceeds a predetermined threshold. The method actuates the plunger out of the barrel by a predetermined amount in response to the detected occlusion and actuates the plunger of the syringe into the barrel until a measured fluid pressure within the barrel of the syringe exceeds another predetermined threshold.
