Title (EN) NEEDLE ASSISTED JET INJECTION DEVICE HAVING REDUCED TRIGGER FORCE
(FR) DISPOSITIF D'INJECTION PAR JET ASSISTÉ PAR UNE AIGUILLE, PRÉSENTANT UNE FORCE DE DÉCLENCHEMENT RÉDUITE
Abstract:
(EN) An exemplary embodiment of an injector includes a trigger mechanism, an energy source, and a user-operable firing-initiation member. The trigger mechanism can include a floating trigger member having a retaining portion, a ram assembly having a ram configured to pressurize a medicament container for expelling a medicament therefrom, the ram assembly further having a floating trigger engagement member configured to engage the retaining portion of the floating trigger member when the floating trigger member is in a pre-firing condition. The energy source can be associated with the ram for powering the ram to expel the medicament, and the user-operable firing-initiation member can be operable for causing an axial rotation of the floating trigger member from the pre-firing condition to a firing condition in which the floating trigger engagement member is released from the retaining portion to allow the energy source to fire the ram.
(FR) La présente invention concerne, dans un mode de réalisation donné à titre d'exemple, un injecteur possédant un mécanisme de déclenchement, une source d'énergie, et un élément commandant le déclenchement activé par l'utilisateur. Ledit mécanisme de déclenchement peut comprendre un élément de déclenchement flottant comportant une partie de retenue, et un ensemble vérin incluant un vérin conçu pour mettre en pression un récipient de médicament afin d'en expulser le médicament. Ledit ensemble vérin comprend en outre un élément de contact de déclenchement flottant, conçu pour venir en contact avec la partie de retenue de l'élément de déclenchement flottant lorsque ledit élément de déclenchement flottant se trouve dans un état de pré-décharge. La source d'énergie peut être associée au vérin pour entraîner l'expulsion du médicament par le vérin. Par ailleurs, l'élément commandant le déclenchement activé par l'utilisateur peut être activé pour entraîner une rotation axiale de l'élément de déclenchement flottant, entre l'état de pré-décharge et un état de décharge dans lequel l'élément de contact de déclenchement flottant est dégagé de la partie de retenue pour permettre à la source d'énergie d'activer le vérin.
