Abstract[English]
Needle insertion mechanism for an injection device comprising a housing, a needle holder holding a needle, a slider moveable from a first position keeping the needle holder in a needle retracted position towards a second position allowing movement of the needle holder to an inserted position. An intermediate member positioned between the needle holder and the slider, being moveable from a blocked position to a release position releasing the needle holder for movement to the inserted position. A biased gearing between the intermediate member and the needle holder which biases the intermediate member towards the release position, and a lock between the intermediate member and the slider locking the intermediate member in the blocked position against the bias of the gearing, wherein movement of the slider towards the second position unlocks the lock and the biased gearing moves the intermediate member into the release position thereby releasing the needle holder.[French]
L'invention concerne un mécanisme d'insertion d'aiguille pour un dispositif d'injection comprenant un boîtier, un support d'aiguille supportant une aiguille, un curseur mobile d'une première position maintenant le support d'aiguille dans une position rétractée d'aiguille vers une seconde position permettant le déplacement du support d'aiguille vers une position insérée. Un élément intermédiaire positionné entre le support d'aiguille et le curseur, est mobile d'une position bloquée à une position de libération libérant le support d'aiguille pour un déplacement vers la position insérée. Un engrenage sollicité entre l'élément intermédiaire et le support d'aiguille qui sollicite l'élément intermédiaire vers la position de libération, et un verrou entre l'élément intermédiaire et le curseur verrouillant l'élément intermédiaire dans la position bloquée contre la sollicitation de l'engrenage, le mouvement du curseur vers la seconde position déverrouillant le verrou et l'engrenage sollicité déplaçant l'élément intermédiaire dans la position de libération, libérant ainsi le support d'aiguille.
