Abstract

La présente invention concerne un orifice en pointe pour une poche de solution de perfusion et, plus particulièrement, une nouvelle structure d'un orifice en pointe comprenant : un corps d'orifice inséré dans un tube de raccordement d'une poche de solution de perfusion ; un capuchon de séparation qui présente une structure creuse et qui est intégralement moulé par injection sur le dessus du corps d'orifice ; une rainure de coupe circonférentielle permettant au corps d'orifice et au capuchon de séparation d'être raccordés l'un à l'autre pour pouvoir être coupés dans une direction circonférentielle ; et un élément de blocage des fuites de liquide qui est installé sur l'extrémité inférieure d'un tube de drainage du corps de l'orifice et qui est un matériau en film souple, l'orifice en pointe étant essentiellement capable de bloquer les médicaments laissés dans la poche de solution de perfusion pour les empêcher de fuir par le tube de drainage après qu'une pointe a été retirée du tube de drainage.
