Abstract: An IV line identification system enables ready identification of an IV line and its associated fluid source and output from other IV lines with their fluid sources and outputs. The IV line identification system includes lights that are coupled to a specific IV line. The lights can identify specific locations on the IV line, such as an entry end by an IV bag and an output end by a needle or port associated with a patient. The lights can also identify the portions of the IV line that enter and exit a pump. The lights can also be selectively turned on when a specific IV line needs to be identified, and turned off when the IV line does not need to be individually identified. The lights may be colored to distinguish between the lights associated with another IV line.
