ABSTRACT:
A clamp having a first clamp body, a second clamp body, and a clamping structure coupled to at least one of the first and second clamp bodies. One or both of the clamp bodies form a channel adapted to receive a tube. The clamping structure is movable in the channel to control the flow rate of a fluid flowing through the tube. In one embodiment, the clamp is provided as a rotary clamp having clamp bodies that are adapted to be rotated relative to each other to control the flow rate of a fluid through a tube disposed in the rotary clamp. The rotary clamp has a substantially linear, or otherwise pre-determined, relationship between flow rate of a fluid flowing through the tube and rotation of the second clamp body.
