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. The removal of the distally directed pressure from the reseal member will cause it to resiliently return to the first position wherein the aperture reassumes the closed configuration.

A needleless injection site, comprising: a housing defining: an interior chamber; a central opening which communicates with the interior chamber; an elongate, proximally extending dilator projection portion which is coaxially aligned with said central opening; and an elongate, distally extending adapter portion, said dilator projection and adapter portions defining a continuous fluid passage; a reseal member disposed within said central opening and said interior chamber, said reseal member having an elastically openable and closable aperture formed therein and normally residing in a first position within the housing wherein the aperture is in a closed configuration, the dilator projection portion of the housing extending into the reseal member; said reseal member being 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, and the removal of the distally directed pressure therefrom will cause the reseal member to resiliently return to the first position wherein the aperture reassumes the closed configuration.
