Abstract

Un auto-inyector de dos dosis por un medicamento en donde el bloqueo y la liberación del resorte impulsor (27) del auto-inyector se controla a través de medios de guía escalonados (16, 24) con rampas para dos deslizamientos sucesivos a lo largo de los medios de deslizamiento (28, 29) operados por el resorte y conectados a la jeringa (21) y el émbolo (26) relevante. Los medios de guía y los medios de deslizamiento pueden girar con relación entre sí y a la dirección 'de deslizamiento, mientras la jeringa puede deslizarse únicamente axialmente, y el control de activación para cada deslizamiento se obtiene al oprimir un activador (30), axialmente deslizable con relación a un miembro estacionario (1), contra la piel del paciente para empujar los medios de deslizamiento primero dentro de una rampa y entonces dentro de la otra rampa de los medios de guía. Para habilitar o deshabilitar el deslizamiento de los medios de deslizamiento dentro de los medios de guía se proporciona un miembro de armado angularmente móvil (11) formado con un riel de guía (14) sustancialmente igual al del miembro estacionario en donde se forman los medios de guía. Siguiendo dos desplazamientos de armado angulares subsecuentes del miembro móvil con relación al miembro estacionario las rampas y el riel de guía se alinean radialmente para permitir que los medios de deslizamiento se deslicen bajo la acción del resorte y por lo tanto suministren la primera dosis y entonces la segunda dosis.
