Abstract

A contrast dispensing system (10) including a mating pair of luer connectors (112, 202) to couple a reusable set (100) and a disposable set (200), a mating pair of luer connectors (204, 218) to couple the disposable set (200) to a manifold (16), a pair of luer connectors (230, 232) to couple a control syringe (18) to the manifold (16), and/or a pair of luer connectors (234, 236) to couple the manifold (16) to a patient catheter (238), wherein one or both of the connectors of a pair of coupled connectors (112, 202; 204, 218; 230, 232; 234, 236) is comprised of low surface energy plastic material, such as high density polyethelene, to reduce or eliminate sticking together from expelled (312) contrast media (14).
