Abstract

L’invention concerne un dispositif d’injection sans aiguille. Le dispositif d’injection comporte un boîtier qu’un utilisateur peut saisir et un ensemble de seringue attaché au boîtier de manière mobile. L’ensemble de seringue est configuré pour expulser du fluide injectable par une buse lorsqu’un gaz sous pression est appliqué sur l’ensemble de seringue. Le dispositif d’injection comporte également un mécanisme d’apport de gaz sous pression disposé à l’intérieur du boîtier et configuré pour réaliser l’application sélective de gaz sous pression sur l’ensemble de seringue. Le mécanisme d’apport de gaz sous pression est au moins partiellement actionné par pression de la buse sur un site d’injection de façon à provoquer le mouvement de l’ensemble de seringue par rapport au boîtier.
