Method of use

Secondary medication sets are often used in conjunction with primary sets to provide additional therapy (a process often referred to as piggy-backing). Secondary sets are used to infuse medications in addition to the fluids being administered through the primary solution set (usually intermittently). Usually the secondary medication set is attached to the primary set via the Y-site (with the secondary set a ta slightly higher level than the primary set). The roller clamp is moved into its closed position and the fluid container is prepared for use. Using an aseptic technique, the sheath is removed and the spike inserted into the appropriate port of the container. The container is suspended and depending on the manufacturers instructions, the chamber is filled with fluid and the line primed. Usually the chamber is squeezed to allow fluid to flow through the chamber and to displace air upwards. Fluid flow is regulated using a roller clamp. The needle at the distal end of the set is inserted into the injection port of a Y-site in a primary solution set (or a needle-free connector at the Y-site, depending on what set is used) The secondary set is designed to prevent back flow into either the primary or secondary set during parallel infusions thus preventing bolus infusion.
