Patent

CA 2653328

An injection device (210; 1 10) is provided that includes a damping element (225; 125) which acts between a syringe carrier (222; 122) and a sleeve (219; 1 19) to cushion the impact as they come into contact, thereby reducing the transmission of energy from the impact to the components of a drive (230, 231, 232, 234; 130, 131, 132, 134) and preventing their fracture. The damping element (225; 125) also reduces the noise, which may be distressing to a user of the device (210; 110), produced when the syringe carrier (222; 122) and the sleeve (219; 1 19) come into contact and reduces the pain suffered by a user upon operation of the device (210; 110).

L'invention concerne un dispositif d'injection (210 ; 1 10) comprenant un élément d'amortissement (225 ; 125) agissant entre un support de seringue (222 ; 122) et un manchon (219 ; 1 19) permettant d'amortir l'impact lorsqu'ils entrent en contact, en réduisant ainsi la transmission d'énergie de l'impact aux composants d'une commande (230, 231, 232, 234 ; 130, 131, 132, 134) et en évitant leur fracture. L'élément d'amortissement (225 ; 125) réduit également le bruit, qui peut être pénible pour un utilisateur du dispositif (210 ; 110), produit lorsque le support de seringue (222 ; 122) et le manchon (219 ; 1 19) entrent en contact et réduit la douleur dudit utilisateur lors du fonctionnement du dispositif (210 ; 110).
