    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. A syringe pump for administering an agent to a patient comprises a housing; a lead screw; a linear cam; a half-nut assembly having first and second half-nut arms each having a first end and a second end, wherein the second ends of the first and second half-nut arms are configured to engage with the lead screw, the first and second half-nut arms are pivotally coupled together, the first ends of the first and second half-nut arms are configured to engage with the linear cam such that actuation of the linear cam toward the half-nut assembly causes the first ends of the first and second half-nut arms to pivotally approach each other, and the second ends of the first and second half-nut arms each includes threads configured to engage the lead screw when the first ends of the first and second half-nut arms approach each other caused by actuation of the linear cam; and a plunger head assembly coupled to said half-nut assembly and operative to drive a plunger of a syringe into a barrel of said syringe.

    Abstract: A pump for treating a patient is disclosed that includes a spring- biased plunger 116 biased toward actuation against a tube 216; a cam shaft 190 configured to actuate the spring-based plunger; a lever 104 actuatable between a closed position and an open position; a shaft coupled to the lever, the shaft having a central axis centrally along the length of the shaft, the shaft 118 coupled to the lever to rotate around the central axis in accordance with actuation of the lever; and a lift cam 120 pivotally coupled to the shaft, wherein the lift cam pivots around a lift cam axis, the lift cam axis of the lift cam is parallel to the central axis of the shaft, and the lift cam engages with the spring-based plunger to lift the spring-biased plunger off of the cam shaft as the shaft rotates in accordance with actuating the lever to the open position.
