Abstract:
An injection site for controlling the flow of a fluid between an introducer and a fluid line, the injection site comprising:a housing defining a flow passage which is placeable into communication with the introducer and the fluid line to permit fluid flow therebetween;a reseal member disposed within the housing and movable between a first position whereat the flow passage is obstructed thereby and a second position whereat fluid is permitted to flow through the flow passage; andan expandable and contractible reservoir disposed within the housing and adapted to retain a volume of fluid when expanded;the reseal member being cooperatively engaged to the housing such that the movement of the reseal member to the second position allows the reservoir to be filled with fluid, and the movement of the reseal member to the first position facilitates the contraction of the reservoir and the forcing of at least a portion of any fluid retained therein into the flow passage.
