A device (10) for delivering fluid to a patient including a passageway having a proximal fluid transport tube, a distal fluid transport tube, and a tubular expansion member coupling the fluid transport tubes. A penetrating member (704) is positioned within the expansion member for axial movement between the fluid transport tubes, and has a sharpened distal tip. The device also includes a dispenser (40) for causing fluid from a reservoir (30) to flow to the proximal fluid transport tube, a housing (20) containing the dispenser and the passageway and including an exit port (70) receiving the distal fluid transport tube, and a connecting member secured to the penetrating member. The connecting member is movable by a user from an exterior of the housing and arranged such that movement causes the penetrating member to move between an extended position and a retracted position.

L'invention concerne un dispositif destiné à administrer un fluide à un patient comportant un passage pourvu d'un tube de transport de fluide proximal, un tube de transport de fluide distal, et un élément d'expansion tubulaire couplant les tubes de transport de fluide. Un élément pénétrant est positionné dans l'élément d'expansion pour permettre un mouvement axial entre les tubes de transport de fluide, et présente une pointe distale aiguisée. Le dispositif comprend également un dispositif d'administration destiné à faire s'écouler du fluide provenant d'un réservoir dans le tube de transport de fluide proximal, un logement contenant le dispositif d'administration et le passage, et comportant un port de sortie recevant le tube de transport de fluide distal, ainsi qu'un élément de connexion fixé à l'élément pénétrant. L'élément de connexion peut être déplacé par un utilisateur depuis l'extérieur du logement et agencé de manière que le mouvement fasse se déplacer l'élément pénétrant entre une position déployée afin d'insérer le tube de transport de fluide sous la peau du patient, et une position rétractée.
