Abstract

Un mecanismo de accionamiento (100) para usar con un contenedor de fármaco (50) en una bomba de fármaco, donde el contenedor de fármaco (50) tiene un cilindro (58) y un sello de pistón (60), que incluye una correa, un accionador eléctrico (101) y una interfaz de engranajes. La rotación de la interfaz de engranajes es controlada por el accionador (101). Un montaje de engranajes se acopla de manera rotativa a la interfaz de engranajes. El montaje de engranajes incluye un engranaje principal y un mecanismo de regulación. La liberación de la correa es calibrada por el montaje de engranajes a través del mecanismo de regulación. Un pistón (110, 1110, 2110) se conecta a la correa y se dispone en el cilindro (58) y se encuentra configurado para trasladarse axialmente dentro del contenedor. Un miembro de desviación se dispone al menos parcialmente dentro del cilindro (58) y se retiene en un estado activado entre el pistón (110, 1110, 2110) y la caja de accionamiento, donde la liberación de la correa controla la expansión libre del miembro de desviación desde su estado activado y la traslación axial del pistón (110, 1110, 2110).
