Abstract

Un dispositivo de administración de fármaco para dispensar una dosis de un medicamento líquido con un mecanismo de expulsión impulsable rotacionalmente adaptado para expulsar la dosis del medicamento líquido desde un recipiente de medicamento, un resorte de impulso torsional redondo adaptado para aplicar un par de impulsión al mecanismo de expulsión impulsable rotacionalmente cuando es energizado por un esfuerzo externo, en donde el resorte de impulso torsional redondo encierra un espacio interior de forma y/o extensión variables según el nivel de esfuerzo externo aplicado al resorte de impulso torsional redondo, y al menos un elemento de restricción que define varias superficies de reposo para soportar internamente el resorte de impulso torsional redondo aumentando con el nivel de esfuerzo externo aplicado al mismo, se puede mejorar proporcionando a las superficies de reposo una forma exterior para mantener esencialmente el centro del espacio interior por toda la variación entera del esfuerzo externo aplicable al resorte de impulso torsional redondo.
