Abstract
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 said motor. The sensor senses a rotation of said motor.

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.
Claims24
A syringe pump for administering an agent to a patient, the syringe pump comprising:
- a housing;
- a lead screw;
- a sliding block assembly, said sliding block assembly comprising a threaded section configured for engaging and disengaging from the lead screw, wherein said sliding block assembly is positioned within said housing;
- a plunger head assembly coupled to said sliding block assembly and operative to drive a plunger of a syringe into a barrel of said syringe;
- first and second flange-clamp jaws disposed on the plunger head assembly and configured to grasp onto a plunger flange of the plunger of the syringe, wherein the first and second flange-clamp jaws are configured to actuate between an open position and a closed position;
- a user-controlled actuator disposed on the plunger head assembly and configured for actuation by a user;
- a shaft disposed within the plunger head assembly and operatively coupled to the user-controlled actuator, the shaft being elongated along a length thereby defining an axis along the length, wherein actuation of the user-controller actuator rotates the shaft around the axis;
- and
- a cam disposed slideably around the shaft, wherein the cam includes an engagement surface disposed around the axis of the shaft.
