Abstract[English]
This text concerns a medicament delivery device for expelling multiple doses a medicament from a medicament container. The medicament delivery device comprises a plunger rod assembly comprising a main plunger rod device and an auxiliary plunger rod device which are rotationally coupled, and a biasing member for forcing the plunger rod assembly in the proximal direction. It also comprises a loading mechanism for a user to cause, by twisting a twisting element, a loading step to bias the biasing member. It further comprises an activation mechanism for the user to activate medicament delivery, which comprises an activation button (13) rotationally coupled to the twisting element (12); a cam feature (112); and a cam-cooperating feature (132). The cam feature (112) or the cam-cooperating feature (132) is comprised in the activation button (13), and the other one is couplable to the base assembly. The activation mechanism is operable by the user to activate medicament delivery by pushing the activation button (13) towards proximally from a first position into a second position. And the twisting of the twisting element (12) causes the activation button (13) to be moved towards distally from the second position into the first position by cooperation of the cam feature (112) and the cam-cooperating feature (132).[French]
La présente invention concerne un dispositif d'administration de médicaments pour expulser de multiples doses d'un médicament d'un récipient de médicaments. Le dispositif d'administration de médicaments comprend un ensemble tige de piston comprenant un dispositif tige de piston principal et un dispositif tige de piston auxiliaire qui sont couplés en rotation, et un élément de sollicitation pour forcer l'ensemble tige de piston dans la direction proximale. Il comprend également un mécanisme de chargement permettant à un utilisateur de provoquer, par torsion d'un élément de torsion, une étape de chargement pour solliciter l'élément de sollicitation. Il comprend en outre un mécanisme d'activation pour que l'utilisateur active l'administration de médicament, qui comprend un bouton d'activation (13) couplé en rotation à l'élément de torsion (12) ; un élément de came (112) ; et un élément coopérant avec la came (132). L'élément de came (112) ou l'élément coopérant avec la came (132) est compris dans le bouton d'activation (13), et l'autre peut être couplé à l'ensemble base. Le mécanisme d'activation peut être actionné par l'utilisateur pour activer l'administration de médicament en poussant le bouton d'activation (13) dans la direction proximale d'une première position à une seconde position. Et la torsion de l'élément de torsion (12) provoque le déplacement du bouton d'activation (13) dans la direction distale depuis la seconde position vers la première position par coopération de l'élément de came (112) et de l'élément coopérant avec la came (132).
