PROPHYLACTIC SYSTEMS FOR DENTAL INSTRUMENTS AND METHODS FOR USING THE SAME

摘要

A prophylactic system (100) for a dental hand piece (101) of a selected shape and having an outlet (112) for providing a fluid to an operating field is disclosed. A cover (102) has a shape substantially similar to the hand piece (101) for enclosing the dental hand piece (101) and includes an aperture (118) for communicating with the operating field. An s-shaped valve (600) includes a path (605) for coupling the fluid from outlet (118) of the hand piece (101) to the aperture (118) of the cover.
