A pump for treating a patient is disclosed that includes a spring-biased plunger biased toward actuation against a tube; a cam shaft configured to actuate the spring-based plunger; a lever 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 coupled to the lever to rotate around the central axis in accordance with actuation of the lever; and a lift cam 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.

Medical pump

A syringe pump includes a lead screw, a cam, and an assembly having first and second arms each having a first end and a second end. The second ends of the first and second arms are configured to engage with the lead screw. The first ends of the first and second arms are configured to engage with the cam such that actuation of the cam toward the assembly causes the second ends of the first and second arms to pivotally approach each other. The second ends of the first and second arms each includes threads to engage the lead screw when the second ends of the first and second arms approach each other. The plunger head coupled to the assembly and operative to drive a plunger of a syringe into a barrel of the syringe.

Syringe pump, and related method and system

A pump for administering an agent to a patient includes a housing, a motor, a gearbox, a sensor, and a controller. The motor may be coupled to housing. The gearbox is operatively connected to the motor. The sensor senses a rotation of the motor. The controller acts to control operation of the motor and monitor the quantity of the agent delivered to the patient. The pump also includes a pump assembly such that the pump is configured such that the pump assembly may be interchangeable from a syringe pump assembly and a peristaltic pump assembly.

Syringe pump

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.
