Abstract

A needleless injection site comprising a housing which defines a fluid passage. Disposed within the housing is a reseal member which includes an openable and closable aperture, and an expandable and collapsible reservoir. The reseal member normally resides in a first position within the housing wherein the aperture is closed and the reservoir is collapsed. The reseal member is deformable such that the application of compressive pressure thereto will facilitate the movement thereof within the housing to a second position wherein the reservoir is expanded and the aperture is opened and placed into communication with the fluid passage and the reservoir. The removal of the compressive pressure from the reseal member will facilitate the resilient return thereof to the first position wherein the aperture is closed and the reservoir is collapsed. The collapse of the reservoir is adapted to prevent the creation of a vacuum within the fluid passage when the reseal member resiliently returns to the first position.
