Abstract

Un dispositivo de administracion de medicamentos (1) comprende una carcasa (15), un ensamblado de varilla de piston telescopico (12) para impulsar un tapon (20) de un recipiente de medicamento (9), y un mecanismo accionador (17) para el ensamblado de varilla de piston telescopico. El ensamblado de varilla de piston telescopico (12) comprende un émbolo (35) para impulsar un tapon (20), una llave (40) para permitir un movimiento predominantemente axial entre el émbolo y la carcasa (30), y un accionador de alimentacion (18) acoplado telescopicamente al émbolo y soportado para un movimiento rotacional y axial con relacion a la carcasa. El mecanismo accionador (17) comprende además un accionador de transferencia (16) que actua para hacer rotar el accionador de alimentacion (18). Cuando el accionador de alimentacion (18) rota, se mueve axialmente con relacion a la carcasa (15), expandiéndose telescopicamente con relacion al émbolo (35).
