Abstract[English]
This text concerns a subassembly (2a) for a medicament delivery device for expelling a medicament from a medicament container comprising a plunger. And it concerns a corresponding medicament delivery device. The subassembly (2a) comprises an auxiliary plunger rod device (8) comprising a first abutting structure (80) and, distally therefrom, a snap member (85); an axially compressible biasing member (9); and a bearing member (160) comprising a second abutting structure. In an assembled state of the subassembly (2a), the biasing member (9) is compressed between the first abutting structure (80) and the second abutting structure; and a movement towards distally of the bearing member (160) relative to the auxiliary plunger rod device (8) is blocked by the bearing member (160) abutting the snap member (85). This way, an intermediate securement of the drive spring (9) regarding the assembly of the medicament delivery device can be achieved. The biasing member (9) can be a helical compression spring.[French]
Ce texte concerne un sous-ensemble (2a) d'un dispositif d'administration de médicament permettant d'expulser un médicament à partir d'un récipient de médicament comprenant un piston. Et il concerne un dispositif d'administration de médicament correspondant. Le sous-ensemble (2a) comprend un dispositif de tige de piston auxiliaire (8) comprenant une première structure de butée (80) et, de manière distale à partir de celui-ci, un élément d'encliquetage (85) ; un élément de sollicitation compressible axialement (9) ; et un élément de palier (160) comprenant une seconde structure de butée. Dans un état assemblé du sous-ensemble (2a), l'élément de sollicitation (9) est comprimé entre la première structure de butée (80) et la seconde structure de butée ; et un déplacement vers le côté distal de l'élément de palier (160), par rapport au dispositif de tige de piston auxiliaire (8), est bloqué par l'élément de palier (160) venant en butée contre l'élément d'encliquetage (85). De cette manière, une fixation intermédiaire du ressort d'entraînement (9) concernant l'ensemble du dispositif d'administration de médicament peut être obtenue. L'élément de sollicitation (9) peut être un ressort de compression hélicoïdal.
