A device (10) for delivering fluid to a patient including an exit port assembly (70) adapted to connect to a transcutaneous patient access tool, and a dispenser(40) including at least two laminated layers of material(252, 254) defining a passageway (250) connected to the exit port assembly (70) and an expandable accumulator (243) in fluid communication with the passageway (250) for controlling fluid flow from a reservoir (30) to the exit port assembly (70). The laminated construction provides many benefits including simplifying the design and manufacturing of the device (10) in order to further reduce the size, complexity and costs of the device (10) so that the device (10) lends itself to being small and disposable in nature.

La présente invention concerne un dispositif (10) destiné à apporter du fluide à un patient, ce dispositif comprenant un ensemble orifice de sortie (70) prévu pour être relié à un moyen d'accès transcutané pour le patient et un distributeur (40) comprenant au moins deux couches feuilletées de matière (252, 254) définissant un passage (250) relié à l'ensemble orifice de sortie (70) et un accumulateur extensible (243) qui communique par le fluide avec le passage (250) pour réguler l'écoulement du fluide entre un réservoir (30) et l'ensemble orifice de sortie (70). La structure multicouche présente de nombreux avantages du fait qu'elle simplifie la conception et la fabrication du dispositif (10) ce qui permet de réduire plus encore la taille, la complexité et les coûts du dispositif (10) de sorte que ledit dispositif (10) arrive à être petit et jetable.
