Featured is a vascular access device such as an IV catheter device including a housing, a tubular member and a seal member, and a securing mechanism. The housing includes a proximal and distal portion and a chamber that extends between the proximal and distal portions. The tubular member is coupled to the housing distal portion so it is fluidly coupled to the chamber. The seal member is disposed within the chamber and the securing mechanism secures the seal member distal end to the housing proximal portion so the seal member is sealingly and compressibly retained between a chamber proximal end and the securing mechanism. Such a seal member also is constituted so a portion of the seal member moves axially responsive to an axial force applied to the proximal end.

L'invention a pour objet un dispositif d'accès vasculaire tel qu'un dispositif de cathéter intraveineux formé d'une enveloppe, d'un élément tubulaire, d'un élément formant capuchon et d'un mécanisme de fixation. L'enveloppe se compose d'une partie proximale et distale et d'une chambre qui s'étend entre la partie proximale et la partie distale. L'élément tubulaire est couplé à la partie distale de l'enveloppe de manière à être couplée par voie fluidique à la chambre. L'élément formant capuchon est disposé à l'intérieur de la chambre et le mécanisme de fixation permet de fixer l'extrémité distale de l'élément de capuchon à la partie proximale de l'enveloppe de sorte que l'élément formant capuchon est retenu de manière étanche et compressible entre une extrémité proximale de la chambre et le mécanisme de fixation. Ledit élément formant capuchon est également constitué de sorte qu'une portion de l'élément formant capuchon se déplace axialement en réponse à une force axiale appliquée sur l'extrémité proximale.
