Abstract

L'invention concerne un dispositif médical (10) permettant d'injecter un liquide médical depuis un récipient (60) pour liquide, de type cartouche, dans le corps d'un patient. Ce dispositif comprend une aiguille (50) qui se rétracte automatiquement après utilisation de sorte que l'embout aiguisé contaminé de l'aiguille soit renfermé à l'intérieur dudit dispositif afin de prévenir les piqûres accidentelles. Selon un aspect de l'invention, un élément de verrouillage (90) empêche de manipuler l'aiguille après rétraction de cette dernière. Selon un autre aspect de l'invention, une cartouche permet au dispositif d'être entièrement stérilisé en une étape.
