Abstract
Tubing for use with intravenous delivery of fluids to a patient is provided. The tubing is preferably see-through and includes a tubing wall defining an exterior surface and an interior surface. The interior and exterior wall surfaces define a channel for transferring intravenous fluid. An indicator for visibly distinguishing one tube from another similar tube is provided. The visible indicator may be a protruding ridge or a depression that traverses a length of the exterior surface, wherein the protruding ridge is helically wrapped around the exterior surface or run down a length of the tube longitudinally. The indicator may have a rectangular cross section, a hemispherical cross section or other suitable shape that traverses a length of the exterior surface. The indicator may additionally be colored or chemiluminescent to make the indicator more visible.
