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 controller acts to control operation of said motor and monitor the quantity of said agent delivered to said 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.

25. A syringe pump for administering an agent to a patient, the syringe pump comprising:
-
a plunger head assembly configured to actuate a syringe; at least one latch configured to releasably secure the syringe to the plunger head assembly; a shaft disposed within the syringe pump; and a cam disposed slideably around the shaft, wherein the cam includes an engagement surface disposed around an axis of the shaft. - View Dependent Claims (26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 57, 58)

54. A syringe pump for administering an agent to a patient, the syringe pump comprising:
-
a plunger head assembly; first and second flange-clamp jaws disposed on the plunger head assembly and configured to grasp onto a plunger flange of a plunger of a 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. - View Dependent Claims (55, 56)
