CA 2664811

A syringe includes a barrel defining a liquid chamber, an aperture and two or more contents indicators; a plunger movable within said barrel whereby movement of the plunger in a first direction causes the liquid chamber to fill with a fluid and movement by the plunger in a second direction causes fluid to be expelled from the liquid chamber through the aperture; and a selecting mechanism disposed on the barrel that is actuated to select only one of the contents indicators.

L'invention concerne une seringue comprenant un cylindre qui définit une chambre de liquide, une ouverture et au moins deux indicateurs de contenu; un plongeur mobile à l'intérieur du cylindre, le déplacement dudit plongeur dans une première direction entraîne le remplissage de la chambre de liquide par un fluide, le déplacement du plongeur dans une seconde direction entraînant l'éjection de ce fluide de la chambre de liquide à travers l'ouveture; et un mécanisme de sélection disposé sur le cylindre qui est actionné pour sélectionner uniquement l'un des indicateurs de contenu.
