1. A flow controller for intravenous (IV) tubing, the flow controller comprising:
a first structural member comprising a linear first outer surface and a linear first inner surface disposed at an angle to the first outer surface;
a second structural member comprising a linear second outer surface parallel to the first outer surface and a linear second continuous inner surface parallel to the first inner surface; and
a third structural member disposed on one of the first or second structural member, the third structural member comprising a friction-reducing surface for at least a portion of a cavity disposed between the first and second structural members,
wherein the first structural member is linearly slidable along a length of the IV tubing disposed in the cavity to compress a portion of the IV tubing to control flow of a medical fluid through the IV tubing.
