Abstract
An air emitting light and shielding apparatus for dental treatment comprised of a pressurized air source connected to an adjustably positionable air emitting light formed so as to develop an air envelope substantially surrounding the face and oral cavity or other body parts of a patient residing in a selected position in the dental chair or other operating table including positions in which the patient may be tilted such that vapors, blood, saliva splash, dental particles, or other foreign matter propelled from the patient's oral cavity during drilling, air-water syringing, or the like, are deflected by the inner boundary of the air envelope and are transported downstream of the patient's oral cavity for collection on a disposable patient drape thereby preventing the same from reaching the face and respiratory tract of a dental team member operating on the patient. The apparatus may also be used in related medical applications, such as in conjunction with an operating table where the patient may move or be moved about the table surface.
