Abstract[English]
An on-body injection device (3) comprising: a housing (9) provided with a medicament inlet (11), a movable member channel (13) arranged in the housing (9), a movable member (15) arranged in the movable member channel (13), the movable member channel (13) having a fluid inlet (13a) in fluid communication with the medicament inlet (11), and a fluid outlet (13b), wherein the movable member (15) is configured to move in the movable member channel (13), by a built-up overpressure inside the movable member channel (13) relative to a pressure on the movable member (15) outside the movable member channel (13), from a first movable member position in which the movable member (15) blocks the fluid outlet (13b) to a second movable member position in which the fluid outlet (13b) is in fluid connection with the fluid inlet (13a), a skin penetration device (21) configured to move from a starting position to a skin penetration position, a conduit (22) connected to the skin penetration device (21) and to the fluid outlet (13b), and a movable structure (23) pretensioned in a direction away from the movable member (15), wherein the movable member (15) is configured to engage with the structure (23) when the movable member (15) is in the first movable member position, preventing the structure (23) from moving away from the movable member (15), and wherein the movable member (15) is configured to disengage from the structure (23) when the movable member (15) is moved towards the second movable member position, causing the pretensioned structure (23) to move away from the movable member (15) to an intermediate position, bringing the skin penetration device (23) from the starting position to the skin penetration position.[French]
La présente invention concerne un dispositif d'injection sur le corps (3) comprenant : un boîtier (9) pourvu d'une entrée de médicament (11), un canal d'élément mobile (13) agencé dans le boîtier (9), un élément mobile (15) agencé dans le canal d'élément mobile (13), le canal d'élément mobile (13) présentant une entrée de fluide (13a) en communication fluidique avec l'entrée de médicament (11), et une sortie de fluide (13b), l'élément mobile (15) étant conçu pour se déplacer dans le canal d'élément mobile (13), par une surpression intégrée à l'intérieur du canal d'élément mobile (13) par rapport à une pression sur l'élément mobile (15) à l'extérieur du canal d'élément mobile (13), à partir d'une première position d'élément mobile dans laquelle l'élément mobile (15) bloque la sortie de fluide (13b) vers une seconde position d'élément mobile dans laquelle la sortie de fluide (13b) est en communication fluidique avec l'entrée de fluide (13a), un dispositif de pénétration cutanée (21) conçu pour se déplacer d'une position e départ à une position de pénétration cutanée, un conduit (22) relié au dispositif de pénétration cutanée (21) et à la sortie de fluide (13b), et une structure mobile (23) précontrainte dans une direction s'éloignant de l'élément mobile (15), l'élément mobile (15) étant conçu pour venir en prise avec la structure (23) lorsque l'élément mobile (15) est dans la première position d'élément mobile, empêchant la structure (23) de s'éloigner de l'élément mobile (15), et l'élément mobile (15) étant conçu pour se désolidariser de la structure (23) lorsque l'élément mobile (15) est déplacé vers la seconde position d'élément mobile, amenant la structure précontrainte (23) à s'éloigner de l'élément mobile (15) vers une position intermédiaire, amenant le dispositif de pénétration cutanée (23) de la position de départ à la position de pénétration cutanée.
