ABSTRACT:
A normally-closed valve that can be easily connected and disconnected. Disposed in the fluid passageway through the valve is a cylindrical member that may be moved between an open position and a closed position. A spring holds the member in the closed position, and a leur-type cannula may be inserted into the valve to push the member into the open position. Two sealing rings are mounted around the cylindrical member. These rings prevent flow through the valve when the member is in its closed position. Two sets of channels are placed in the walls of the passageway to permit flow around the sealing rings when the member is in its open position.
