Abstract: A needleless injection site comprising a housing which defines an interior chamber and a central opening which communicates with the interior chamber. The housing further defines a proximally extending dilating projection portion which is coaxially aligned with the central opening and distally extending adapter portion. The dilator projection and adapter portions define a continuous fluid passage. Disposed within the central opening and the interior chamber is a reseal member which has an elastically openable and closable aperture formed therein. The reseal member normally resides in the first position within the housing wherein the aperture is in a closed configuration. The reseal member is deformable such that the application of distally directed pressure thereto will cause the reseal member to distally advance within the housing to a second position wherein the aperture assumes an open configuration and communicates with the fluid passage.
