Abstract

Dispositivo de autoinyección que tiene un extremo delantero y un extremo trasero dispuesto para comprender: - un alojamiento trasero y un alojamiento (10) de recipiente, conectados de manera liberable entre sí; - un recipiente (12) de medicamento dispuesto dentro del alojamiento de recipiente, en el que el recipiente tiene una abertura delantera con o para un elemento de administración para administrar el medicamento a través de la misma y al menos un tapón móvil; - un mecanismo de fijación de dosis que puede fijar y volver a fijar una dosis de medicamento; - una tuerca (18) de accionamiento conectada de manera liberable con el mecanismo de fijación de dosis; caracterizado porque dicho dispositivo comprende además: - un vástago (14) de émbolo hueco conectado de manera rotatoria con dicha tuerca de accionamiento y dispuesto para tener su extremo delantero en contacto con dicho tapón; - un elemento (46) de acumulación de energía que tiene un primer extremo conectado con el mecanismo de fijación de dosis y un segundo extremo conectado con un punto fijo del alojamiento trasero, de tal manera que cuando se actúa sobre dicho mecanismo de fijación de dosis para fijar una dosis, dicho elemento de acumulación de energía acumula energía como al menos una etapa predeterminada; - un mecanismo (24) de activación conectado de manera liberable con dicha tuerca de accionamiento y que puede bloquear dicha tuerca de accionamiento frente a la rotación cuando está fijándose una dosis y liberar dicha tuerca de accionamiento cuando se activa manualmente dicho mecanismo de activación de tal manera que dicho vástago de émbolo hueco se desplaza linealmente hacia el extremo delantero del dispositivo mediante la rotación de dicha tuerca de accionamiento debido a la energía acumulada en el elemento de acumulación de energía y transferida a través del mecanismo de fijación de dosis; - un mecanismo de colocación conectado operativamente con dicho vástago de émbolo hueco y que puede bloquear dicho vástago de émbolo hueco frente a un desplazamiento elástico y axial mediante rotación; en el que dicho mecanismo de colocación comprende una primera tuerca (28) de bloqueo rotacionalmente bloqueada pero axialmente deslizable que rodea a dicho vástago de émbolo hueco y dispuesta para actuar conjuntamente con medios (38) de bloqueo flexibles dispuestos en dicho alojamiento trasero para bloquear dicha primera tuerca de bloqueo frente a la rotación; y un elemento (52) elástico dispuesto dentro de dicho vástago de émbolo hueco que puede permitir que dicho vástago de émbolo hueco se desplace de manera elástica y axial cuando se desbloquea dicha primera tuerca de bloqueo.
