<p>A belt driven infusion pump (10) for emptying the contents of a syringe is disclosed. The pump includes a syringe pusher (22) including an antisiphon catch and a pressure detector (92) which is used for detecting occlusions or the end of infusion. A syringe clamp (128) for locking a syringe in place is also provided. The syringe clamp is spring-loaded and lockable. A syringe position detector is provided to ensure the proper placement of the syringe prior to and during pumping. A control knob (26) is provided on the face of the pump (10) for controlling both the locking of the syringe barrel clamp and the coupling of the drive belt with a d.c. motor. The pump includes a housing (12) having an elongated slot (112) through which the syringe pusher (22) is connected to the drive belt. A sealing band (120) is connected to the syringe pusher (22) and is moveable with the syringe pusher (22) for sealing the slot against moisture or other contaminants. A pole clamp (30) assembly is incorporated within the pump housing and includes a clamping arm for securing the pole between the clamping arm and the housing. The clamping arm is movable to a storage position where it is substantially flush with the outer surface of the pump housing (12). <IMAGE></p>
