ABSTRACT:
A self-priming injection site having a stopper that resists dislocation or removal from the injection site. The stopper is positioned within the plastic housing between a top with an open center and an intermediate ledge having an upturned lip. The stopper includes an annular groove that receives the upturned lip of the intermediate ledge, to assist in holding the stopper in compression within the housing. An arm portion allows the intravenous fluid to enter the injection site on a path approximately parallel to and immediately adjacent to the ledge and the bottom of the stopper. A check valve may be positioned within the arm portion.
