Abstract

Un dispositivo de administración de fármacos puede incluir una carcasa que tiene una abertura y un recipiente de almacenamiento de fármacos, que incluye un elemento de administración con un extremo de inserción configurado para extenderse, al menos parcialmente, a través de la abertura durante un estado de administración. El dispositivo también puede incluir un elemento protector situado de manera móvil adyacente a la abertura y un émbolo que tiene una parte de cuerpo cilíndrica en general, que se extiende a lo largo de un eje longitudinal del recipiente, y al menos una pestaña que se extiende radialmente hacia fuera desde la parte de cuerpo, en donde el émbolo se puede mover hacia el extremo distal del recipiente para expulsar un fármaco a través del elemento de administración. El dispositivo puede incluir además un elemento de presión del émbolo, configurado para impeler el émbolo hacia el extremo distal del recipiente, y un elemento liberador, que define una guía configurada para recibir la o las pestañas, y un indicador configurado para generar una señal audible que indique un final de la administración del fármaco.
