A needleless injection site comprising a housing (12) which defines an interior chamber (22) and a central opening (24) which communicates with the interior chamber. The housing further defines a proximally extending dilator projection portion (38) which is coaxially aligned with the central opening and a distally extending adapter portion (40). The dilator projection and adapter portions define a continuous fluid passage. Disposed within the central opening and the interior chamber is a reseal member (60) 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 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.
L'invention porte sur un site d'injection sans aiguille comportant un logement (12) délimitant une chambre intérieure (22) et une ouverture centrale (24) communiquant avec ladite chambre. Le logement délimite par ailleurs une partie saillante de dilatation (38) proximale et coaxiale avec l'ouverture centrale, ainsi qu'une partie d'adaptation (40) distale. Lesdites parties de dilatation et d'adaptation constituent un passage continu pour un fluide. Un élément de refermeture (60) occupant l'ouverture centrale et la chambre intérieure comporte un orifice ouvrable et refermable élastiquement. L'élément de refermeture qui se trouve normalement dans une première position à l'intérieur du logement lorsque l'orifice est fermé est déformable si bien que si on lui applique une pression distale, il avance distalement dans le logement jusqu'à une deuxième position où l'orifice, ouvert, communique avec le passage pour fluide.
