Abstract

La presente invención se dirige generalmente a un dispositivo de inyección para seleccionar y dispensar una variedad de dosis variables de usuario de un medicamento. El dispositivo de inyección comprende un alojamiento (10) que tiene un eje longitudinal (I), un miembro de ajuste de dosis (60; 80) que gira con respeto al alojamiento (10) durante el ajuste de la dosis, un miembro accionador (40) que se limita rotacionalmente al alojamiento (10) en un primer modo de ajuste de dosis y en el cual es que gira con respecto al alojamiento (10) en un segundo modo de dispensación de dosis, un elemento de fijación (100) que se limita de manera permanente rotacionalmente al alojamiento (10) y movible con respecto al alojamiento (10) en una dirección paralela al eje longitudinal (1) entre una primera posición de ajuste de dosis y una segunda posición de dispensación de dosis, un botón de accionamiento (70) movible con respecto al alojamiento en una dirección paralela al eje longitudinal (1) entre una primera posición de ajuste de dosis y una segunda posición de dispensación de dosis para cambiar el dispositivo de inyección entre el primer modo de ajuste de dosis y el segundo modo de dispensación de dosis, un trinquete (42, 120) para transmitir par de torsión del miembro de ajuste de dosis (60) al miembro accionador (40) durante la dispensación de dosis y permitir el movimiento rotacional relativo entre el miembro de ajuste de dosis (60) y el miembro accionador (40) durante el ajuste de la dosis, el trinquete (42, 120) que comprende las primeras características de trinquete (43) limitadas rotacionalmente al accionador (40) y las segundas características de trinquete (121) limitadas rotacionalmente al miembro de ajuste de dosis (60), y un resorte (130). El resorte (130) predispone el elemento de fijación (100) y el botón de accionamiento (70) en su primera posición de ajuste de dosis y predispone las primeras características del troquel (43) en el acoplamiento con las segundas características del trinquete (121).
