CA 2205921

A valve including a substantially ridig cannula and a valve member positioned for operable communication with the cannula. The valve member is formed from a substantially resilient material, having a slit extending therethrough, and movable with respect to the cannula between a first closed position and a second open position. The slit is substantially closed by the resiliency of the material of the valve member when the valve member is positioned in the first closed position and the cannula cooperates to extend through the slit during movement of the valve member from the first closed position to the second open position to establish a fluid flow path through the cannula and the valve member. A sealing member is also provided independant from a flow of fluid within the fluid flow path to provide positive sealing of the slit when the valve member is positioned in the first closed position.

Obturateur comportant une canule sensiblement rigide et un élément obturant placé pour pouvoir communiquer avec la canule. L' élément obturant constitué d'un matériau sensiblement élastique et comportant une fente le traversant peut se déplacer par rapport à la canule entre une première position de fermeture et une deuxième position d'ouverture. La fente est pratiquement fermée du fait de l'élasticité du matériau de l'élément obturant lorsque ce dernier se trouve en position de fermeture tandis que la canule coopère en s'étendant à travers la fente lors du déplacement de l'élément obturant entre la position de fermeture et la position d'ouverture à l'établissement d'un chemin d'écoulement du fluide traversant la canule et l'obturateur. Par ailleurs, un élément de fermeture indépendant de l'écoulement de fluide traversant le chemin d'écoulement assure mécaniquement la fermeture lorsque l'élément obturant est placé en position d'ouverture.
