Abstract
Tubing through which fluid flow is to be regulated is placed in a regulating clamp wherein it is clamped between a movable roller wheel and a surface of the clamp. Flow rate through the tubing is changed as determined by longitudinal adjustment of the position of the roller wheel. A full shut-off of flow through the tubing at a particular shut-off zone of the roller clamp is assured by means of ledge elements extending from the sidewall of the housing. These ledge elements, so as to provide a transitional deformation, are located in spaced relation to the clamping surface and are configured monotonically to provide a transitional and monotonically configured deformation of the tubing to avoid accidental rupture thereof, at the same time fully confining the tubing to prevent the formation of lumens in the peripheral edge portions thereof. In addition, full shut-off of the edge portion of the tubing is assured for parallel acting roller clamps, throughout the travel range of the wheel, if so desired. For inclined ramp roller clamps, improved tube confinement is offered.
