Abstract

La présente invention concerne un dispositif (10) de remplissage et de vidage d'une cartouche (42) comprenant une ouverture permettant de contenir une substance. Ledit dispositif comprend un corps (12), le corps (12) pouvant être raccordé à la cartouche (42) et au moins partiellement inséré dans l'ouverture de la cartouche (42) dans un état monté verticalement, une conduite de remplissage (14) pouvant être raccordée à une alimentation en fluide, la conduite de remplissage (14) s'étendant au moins partiellement à travers le corps (12), et au moins une première lancette d'aspiration (28) s'étendant à travers le corps (12). Le dispositif (10) comprend en outre un dispositif antireflux (26) qui empêche le fluide fourni par le biais de la conduite de remplissage (14) d'être ré-aspiré dans la conduite de remplissage (14). Grâce au dispositif antireflux (26), aucune substance diluée et/ou dissoute ne peut s'écouler en retour à travers la conduite de remplissage (14) et vers l'alimentation en fluide, ce qui empêche la contamination de l'alimentation en fluide.
