Abstract

Un dispositivo de administración de multidosificación controlada para usarse con una jeringa incluye un alojamiento, una barra de émbolo y una carcasa de accionamiento. El alojamiento tiene una cámara que se extiende axialmente que incluye aberturas en cada extremo, el extremo distal estando adaptado para unirse al cilindro de jeringa. La barra de émbolo incluye un botón de contacto en el extremo proximal de un eje alargado y una característica de empuje en el extremo distal. La carcasa de accionamiento está colocada para traslación axial dentro de la cámara que se extiende axialmente. La carcasa de accionamiento incluye una cabeza posicionada para traslación a lo largo del eje para proporcionar administración de dosis, una pluralidad de superficies de acoplamiento para acoplamiento por medio de la característica de empuje, y una característica de retención que inhibe el movimiento proximal de la carcasa de accionamiento cuando se acopla. La depresión del botón de contacto traslada axialmente el eje alargado y característica de empuje en acoplamiento con dicha al menos una de las superficies de acoplamiento para trasladar la carcasa de accionamiento en la dirección distal, por lo cual la característica de retención se acopla para mantener la posición axial de la carcasa de accionamiento en el alojamiento después de la administración de dosis, y una estructura de desviación traslada la barra de émbolo en la dirección proximal después de la traslación de la carcasa de accionamiento.
