摘要：
Injector (12), comprising: a housing (14)； a container part (20) disposed within the housing (14), which defines a fluid chamber (22) containing a medicament, and which includes a plunger (28) disposed movably therein and defining a part of the fluid chamber (22)； a firing mechanism that includes a piston (60) associated with the piston (28) and extending axially therefrom； the firing mechanism further comprising a pair of elastically deformable closure elements (55) disposed movably within the housing (14) and configured to engage a part of the piston (60) in closing connection； the firing mechanism further comprising an inner housing (54)； a safety element (80), and a trigger (64) disposed movably within the housing (14) between a prepared position in which the closing elements (55) are held together with the piston part (60) by the trigger (64) and a firing position in which the closing elements (55) are released, allowing the movement of the piston (60)； characterized in that the safety element (80) is positionable with respect to the housing (14) to restrict the movement of the trigger (64) to the firing position； and, in addition, by the fact that the closure elements (55) extend from the proximal end of the inner housing (54), in which an axial movement of the trigger (64) in a proximal direction disengages the closure connection between the closing elements (55) and the piston (60).Inyector (12), que comprende: una carcasa (14)； una parte de recipiente (20) dispuesta dentro de la carcasa (14), que define una cámara de fluido (22) que contiene un medicamento, y que incluye un émbolo (28) dispuesto de manera móvil en la misma y que define una parte de la cámara de fluido (22)； un mecanismo de disparo que incluye un pistón (60) asociado al émbolo (28) y que se extiende axialmente desde el mismo； comprendiendo el mecanismo de disparo, además, un par de elementos de cierre deformables elásticamente (55) dispuestos de manera móvil dentro de la carcasa (14) y confi
