First Claim
1. A clamping apparatus for holding an object to an elongate member, said apparatus comprising:
- a wall;
clamping means for clamping the wall to the elongate member, the clamping means being moveable in a first direction away from the wall and in a second direction towards the wall and the clamping means comprising a clamping surface for interaction with the object;
a carriage secured to the housing such that the carriage is moveable by a relatively small distance with respect to the wall but such that the clamping means is moveable a relatively large distance with respect to the carriage;
locking means for locking the carriage to the clamping means; and
tightening means for urging the carriage in the second direction once the clamping means has moved partially away from the wall and the carriage is locked to the clamping means, thereby clamping the elongate member between the wall and the clamping surface.

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.

9. A clamping apparatus for holding an object to an elongate member, the apparatus comprising:
-
a wall; a slide means slidable in a first direction away from the wall and in a second direction towards the wall and comprising a clamping surface for interaction with the object; tightening, means for urging the slide in the second direction, the tightening means comprising; cam means rotatably fixed relative to the wall; a carriage actuable by the cam means, such that the slide is slidable relative to the carriage; locking means for locking the carriage to the slide means, such that rotation of the cam means tightens the slide against the elongate member with the carriage locked to the slide means, thereby clamping the elongate member between the clamping surface and the wall. - View Dependent Claims (10, 11)

13. A syringe pump comprising a housing, a syringe pusher, means for driving the pusher, means for securing a syringe to the housing and a clamp for securing the housing to an elongate object, the clamp comprising:
-
a wall; clamping means for clamping the wall to the elongate member, the clamping means being moveable in a first direction away from the wall and in a second direction towards the wall and the clamping means comprising a clamping surface for interaction with the object; a carriage secured to the housing such that the carriage is moveable by a relatively small distance with respect to the wall but such that the clamping means is moveable a relatively large distance with respect to the carriage; locking means for locking the carriage to the clamping means; and tightening means for urging the carriage in the second direction once the clamping means has moved partially away from the wall and the carriage is locked to the clamping means, thereby clamping the elongate member between the wall and the clamping surface. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
