An improved medication delivery device is a pen sized instrument that is powered by compressed inert gas. The needle-less injector device contains pre-filled and pre-measured medication dosages. The injector device has a pre-filled and self-contained compressed gas for providing pressure to inject the medication into the skin surface without the use of a needle. The injector device has a pressure sensitive deployment mechanism which insures proper seating of the injector face against the skin surface before medication delivery is accomplished. The needle-less injector device assures safe use by inexperienced operators (including children) under adverse conditions.

Ce dispositif amélioré d'administration de médicaments, de la taille d'un stylo, comporte un gaz inerte comprimé assurant la propulsion des médicaments. Ce dispositif d'injection sans aiguille contient des doses de médicaments pré-introduites et pré-mesurées, ainsi que du gaz comprimé pré-introduit et indépendant qui fournit la pression nécessaire pour injecter un médicament sous la surface de la peau sans avoir à utiliser une aiguille. Il comprend un mécanisme de déploiement sensible à la pression qui assure une assise appropriée de la face de l'injecteur à la surface de la peau avant l'administration du médicament. Ce dispositif d'injection sans aiguille permet à des manipulateurs inexpérimentés (y compris des enfants) une utilisation en toute sécurité dans des conditions difficiles.
