Title
(EN) BRUISELESS CANNULA
(FR) CANULE SANS CONTUSION
Abstract
(EN) A needle device (6) comprising a housing which can be mounted to an injection device (1). The housing comprises a first housing element (13) provided towards a proximal end of said needle device (6) and a second housing element (15) provided towards a distal end of said needle device (6). A cutting element (14) having a sharp proximal end is arranged at a proximal end of said first housing element (13). A cannula having a blunt proximal end (11) is fitted to the second housing element (15) and an opening for the cannula (11) is provided at the proximal end of the first housing element (13). The first housing element (13) and the second housing (15) element are moveable relative to each other between an extended position where the proximal end of the cannula (11) does not extend beyond the proximal end of the cutting element (14) and a compressed position where the cannula (11) extends through the opening of the first housing element (13) and past the proximal end of the cutting element (14). This construction greatly reduces the risk of post-treatment bruising and tissue trauma.
(FR) L'invention concerne un dispositif à aiguille (6) comprenant un boîtier qui peut être monté sur un dispositif d'injection (1). Le boîtier comprend un premier élément de boîtier (13) disposé vers une extrémité proximale dudit dispositif à aiguille (6) et un second élément de boîtier (15) disposé vers une extrémité distale dudit dispositif à aiguille (6). Un élément de coupe (14) ayant une extrémité proximale pointue est disposé à une extrémité proximale dudit premier élément de boîtier (13). Une canule ayant une extrémité proximale émoussée (11) est adaptée sur le second élément de boîtier (15) et une ouverture pour la canule (11) est disposée à l'extrémité proximale du premier élément de boîtier (13). Le premier élément de boîtier (13) et le second élément de boîtier (15) sont déplaçables l'un par rapport à l'autre entre une position étendue où l'extrémité proximale de la canule (11) ne s'étend pas au-delà de l'extrémité proximale de l'élément de coupe (14), et et une position comprimée où la canule (11) s'étend à travers l'ouverture du premier élément de boîtier (13) et au-delà de l'extrémité proximale de l'élément de coupe (14). Cette construction réduit considérablement le risque d'une contusion et d'un traumatisme tissulaire de post-traitement.
