Patent

CA 2694239

An applicator, for example an injector (100), includes a flow control means including a first member (2) and a second member (6) for controlling flow from an inlet (4) to an outlet (5). A hinged linkage (17) is provided having a first end (18) rotatably engaged with the first member and a second end (19) rotatably engaged with the second member. The linkage (17) is moveable between a collapsed position and an over-centre locked position which prevents relative movement of the first member (2) towards the second member (6). Linkage unlocking means(28) are provided which move the hinge (22) away from the over-centre locked position so that the first and second members can be moved together. A similar linkage (10) prevents unwanted movement of a needle shroud (8). A needle shroud (8) which can be used to remove the needle (7) from the injector (100) is also described.

L'invention concerne un applicateur, par exemple un injecteur (100), qui comprend des moyens de commande d'écoulement comprenant un premier élément (2) et un second élément (6) pour commander l'écoulement provenant d'un orifice d'entrée (4) vers un orifice de sortie (5). Une liaison articulée (17) est disposée, ayant une première extrémité (18) engagée à rotation avec le premier élément et une seconde extrémité (19) engagée à rotation avec le second élément. La liaison (17) est mobile entre une position pliée et une position verrouillée d'arc-boutement qui empêche un mouvement relatif du premier élément (2) vers le second élément (6). Des moyens de déverrouillage de liaison (28) sont prévus, lesquels déplacent la charnière (22) hors de la position verrouillée d'arc-boutement, de telle sorte que les premier et second éléments peuvent être déplacés ensemble. Une liaison analogue (10) empêche un mouvement non souhaité d'une coiffe d'aiguille (8). L'invention concerne également une coiffe d'aiguille (8) qui peut être utilisée pour retirer l'aiguille (7) de l'injecteur (100).
