Abstract
A belt driven infusion pump for emptying the contents of a syringe is disclosed. The pump includes a syringe pusher including an antisiphon catch and a pressure detector which is used for detecting occlusions or the end of infusion. A syringe clamp 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 is provided on the face of the pump 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 having an elongated slot through which the syringe pusher is connected to the drive belt. A sealing band is connected to the syringe pusher and is moveable with the syringe pusher for sealing the slot against moisture or other contaminants. A pole clamp 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.
