A vial access pin includes opposed proximal and distal ends. The proximal end of the vial access pin is configured for mounting to a hypodermic syringe. The distal end of the vial access pin defines a cannula. The cannula includes a sharp point for piercing an elastomeric seal of a vial. A lumen extends through the cannula and communicates with the proximal end of the pin. A fluid flow aperture extendsthrough the cannula at a location spaced from the distal end. The aperture enables a vial to be substantially drained without repositioning the cannula relative to the vial. An ampule access tube can be mounted over the cannula to cover the aperture and enable fluid in an ampule to be accessed.

Cette invention concerne une aiguille de seringue présentant un bout proximal et un bout distal. Le bout proximal de l'aiguille a une configuration adaptée pour la fixation à une seringue hypodermique. Le bout distal de l'aiguille creuse comporte une pointe acérée servant à percer le couvercle élastomère d'une fiole. La partie distale de l'aiguille communique avec sa partie proximale grâce à un canal intérieur. Cette partie distale comporte une ouverture d'admission de liquide qui se prolonge sur une certaine distance vers le bout proximal de l'aiguille. Cette ouverture permet de vider la fiole quasi complètement sans avoir à modifier la position de l'aiguille par rapport à celle-ci. Un tube de pompage peut être glissée sur la partie distale de l'aiguille pour obturer l'ouverture d'admission allongée et permettre le soutirage du liquide médicamenteux contenu dans un flacon.
