Abstract

An intravenous (IV) set system comprising a primary IV set defining a primary flow line of the IV set system. The primary flow line can include multiple access points along its length and feeds to a merging fluid pathway proximate to the distal terminus of the primary IV set. At least one secondary IV set with corresponding flow lines can be separably joined to the primary IV set to cause the secondary flow lines to be in fluid communication with the primary flow line. At least one of the IV sets can have a unique set of uniform marking indicia to facilitate rapid identification of the IV sets from other IV sets within the IV set system. Such marked and identified primary and/or secondary IV sets can be allocated to specific medical functions and/or can be for use by specific medical personnel to thereby minimize risk of error in administration of an IV to a patient. The IV set system can further comprise a merging fluid pathway about a primary IV set.
