Abstract

A universal mounting system for attaching any of a variety of I.V. devices to an I.V. pole. The mounting system has both a C-clamp and a spring-actuated clamp. The C-clamp attaches to the I.V. pole with a threaded stud that is manually adjustable with a knob. The spring-actuated clamp secures the I.V. device and is pivotally connected to the C-clamp by a pivot-screw that extends through both a spring and a non-threaded bore that is formed in the C-clamp, and exits at a recess area on the C-clamp. The pivot-screw is threaded into a threaded bore that extends through a projection on the spring-actuated clamp. The projection fits within the recess to prevent pivoting of the spring-actuated clamp relative to the C-clamp. The spring-actuated clamp has two aligned, opposing and spring-loaded clips for holding I.V. devices. The clips pivot and fulcrum together at a pivot point between the ends of each clip so as to bring the clip ends together to a clamped position on an I.V. device.

Claims

a first clamping means for clamping to said elongated member; and

a second clamping means, pivotally connected to said first clamping means for applying a releasable clamping force to said I.V. device thereby holding said I.V. device in a firm yet releasable manner, said second clamping means comprising a spring-biased releasable locking means for both selectively positioning and locking said second clamping means relative to said first clamping means, said releasable locking means comprising in combination a polygonally shaped recess formed on one of said first and second clamping means and a correspondingly shaped locking member projecting from the other of the first and second clamping means, and wherein the recess and locking member fit together in a tight fitting, conformal relationship in any one of a plurality f pivotal orientations at predetermined angles defined by the polygonal shape of the recess.

2. A universal mounting system as defined in claim 1, wherein said first clamping means comprises:

a C-shaped element having a first and a second arm, and a threaded stud having a distal and a proximal end, said threaded stud proximal end having a knob, said threaded stud having external threads between said proximal and distal ends for threadably engaging an internally threaded bore formed through said first arm, whereby the first and second arms of said C-shaped element at least partially surround said elongated member, and the threaded stud manually adjusts with said knob so as to bear the threaded stud distal end against the elongated member to both urge and clamp the elongated member against the second arm.
