Abstract
Abstract An apparatus allowing the provision of light and/or water at the tip of a dental illumination light curing device normally provided without such capability includes a pair of supply lines terminating at their remote end in an adapter capable of connection to a standard air/water connection as found on a dental pedestal. The local ends of the supply lines terminate at the neck of the illuminator, where they are supported upon the neck by a clamp, and interconnect with a pair of nozzle tubes. The nozzle tubes have exits at the illuminator tip, and are secured thereto in a removable manner. The modular nature of the apparatus allows removal and exchange of the nozzle elements as desired to accommodate differing illuminator neck shapes and lengths and permit sterilization and replacement of the nozzle elements.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
232 words
An apparatus for the provision of air and water to the tip of a dental illuminator having a neck terminating at an illumination tip extending from a handpiece, said handpiece further comprising a hand-grip portion, said dental illuminator being operatively connected to an illumination power supply independent of a dental pedestal and without a water or air supply, said apparatus comprising a pair of supply lines having first and second ends, said first ends adapted to connect to air and water supplies on a dental pedestal; a first clamp adapted to be mounted to the neck of said illuminator proximate the handpiece; a pair of connector tubes each having a first end adapted to connect with a second end of one of said supply tubes and a second end adapted to be mounted on and supported by said first clamp, the terminating portions of said supply tubes proximate said second ends projecting through said clamp towards the tip of said illuminator; a second clamp adapted to be mounted to the dental illuminator neck proximate the illumination tip; and a pair of nozzle tubes each having a first end adapted to dispense the supplied material and positioned proximate the tip of the illuminator and being held in position with respect thereto by said second clamp, said second ends of said nozzle tubes being removably connected to said second ends of said connector tubes.
Claim 2
Independent Claim
232 words
An apparatus for the provision of air and water to the tip of a dental illuminator having a neck terminating at an illumination tip extending from a handpiece, said handpiece further comprising a hand-grip portion, said dental illuminator being operatively connected to an illumination power supply independent of a dental pedestal and without a water or air supply, said apparatus comprising a pair of supply lines having first and second ends, said first ends adapted to connect to air and water supplies on a dental pedestal; a first clamp adapted to be mounted to the neck of said illuminator proximate the handpiece; a pair of connector tubes each having a first end adapted to connect with a second end of one of said supply tubes and a second end adapted to be mounted on and supported by said first clamp, the terminating portions of said supply tubes proximate said second ends projecting through said clamp towards the tip of said illuminator; a second clamp adapted to be mounted to the dental illuminator neck proximate the illumination tip; and a pair of nozzle tubes each having a first end adapted to dispense the supplied material and positioned proximate the tip of the illuminator and being held in position with respect thereto by said second clamp, said second ends of said nozzle tubes being removably connected to said second ends of said connector tubes.
Claim 3
Dependent Claim
46 words
The apparatus of claim 1, wherein said first clamp comprises a clamp body having a pair of opposed serrated ends adapted to interengage and retain said body in engagement about said neck; said clamp body having a pair of apertures therethrough to support said connector tubes.
Claim 4
Dependent Claim
28 words
The apparatus of claim 2, wherein said second clamp is a gasket formed of an elastomeric material adapted to surround and embrace said nozzle tubes and said neck.
