Adjustable HVE tip

An adjustable HVE tip which includes:

• (a) a first tubular member having a first generally straight cylindrical primary portion with one end thereof being adapted to be mounted in a dental evacuation system and having a first connection portion formed integrally with the other end of the first primary portion and extending away therefrom at an angle of about 135 degrees, the first primary portion having a plurality of shaped indentations formed in a circular pattern in the exterior surface thereof to facilitate grasping the first primary portion in the shaped indentations, and the first connection portion having a plurality of slots formed in a circular pattern in an interior surface thereof;
• (b) a second tubular member having a second generally straight cylindrical primary portion and having a second connection portion formed integrally with one end of the second primary portion and extending away therefrom at an angle of about 135 degrees, the second connection portion having a plurality of protrusions formed in a circular pattern in an exterior surface thereof;
• and
• (c) the second connection portion being telescopically received within the first connection portion and rotatable relative thereto to permit the first and second primary portions to be adjustably positioned relative to one another at a plurality of predetermined positions, including a first position at which the axes of the first and second primary portions extend in generally parallel relation to one another and in the same plane and a second position at which the axes of the first and second primary portions extend in generally perpendicular relation to one another and in the same plane, and the protrusions in the circular pattern on the second connecting portion being disposed within at least some of the slots in the circular pattern in first connection portion to temporarily fix the location of the first and second connecting portions at said plurality of predetermined positions and thereby provide an indexing connection between the first and second connecting portions.
