Abstract

Un dispositivo de administración de fármacos incluye una carcasa que tiene extremos proximal y distal y un eje longitudinal que se extiende entre ellos, un conjunto de inyección dispuesto al menos parcialmente dentro de la carcasa incluyendo una aguja o una cánula, un conjunto impulsor acoplado operativamente con el conjunto de inyección, un capuchón acoplado de manera deslizable con el conjunto impulsor, y un mecanismo de retención. El conjunto impulsor puede acoplarse para administrar un medicamento a través del conjunto de inyección. El capuchón puede colocarse en una posición extendida en la que al menos un extremo proximal se extiende una distancia más allá del extremo proximal de la carcasa y una posición retraída donde el extremo proximal de la carcasa sobresale una distancia más allá del extremo proximal del capuchón. Al mover el capuchón a la posición retraída se acopla el conjunto impulsor para administrar el medicamento a través del conjunto de inyección. El mecanismo de retención limita el movimiento del conjunto impulsor para restringir el acoplamiento del mismo de modo que se restringe la administración del medicamento por parte del conjunto impulsor a través del conjunto de inyección.
