<p>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 dilator projection portion which is co-axially aligned with the central opening and a 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 a 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. The cessation of the application of distally directed pressure to the reseal member will cause it to resiliently return to the first position wherein the aperture reassumes the closed configuration.</p> |
