Abstract
A nozzle for the simultaneous discharge of first and second fluids through a distal end thereof and for attachment to the hand piece of a dental tool comprising sources of the first and second fluids. The nozzle comprises first and second conduits and coupling means for removably coupling the nozzle to the hand piece. The first and second conduits have coaxial intake ports for fluid communication with the sources of the first and second fluids and coaxial discharge ports at the distal end of the nozzle for discharging the first and second fluids. The first conduit is contained at least partially within the second conduit and the discharge ports are proximately located with respect to one another. Upon coupling of the nozzle to the hand piece, the first conduit is automatically aligned with and connected to the source of the first fluid to enable quick connection and disconnection of the nozzle to the hand piece.
