5. The disposable dental aerosol device of claim 1 wherein the first pressure relief opening has a triangular shape.
6. The disposable dental aerosol device of claim 1 wherein the second pressure relief opening has a triangular shape.
7. A disposable dental aerosol device comprises:
a body having an exterior surface, a front end having an angled opening having a retraction lip portion, a rear end having an opening and a circumferential shoulder stop on the exterior surface of the body with the rear end for receiving a dental valve, a lumen formed between the front end and the rear end, and an interior step within the lumen positioned at the rear end and adjacent to the stop and facing the front end to facilitate directing aerosol and other matter through the lumen and out the opening in the rear end and the lumen having a continuous straight surface from the front end to the opening in the rear end and opposite the interior step, wherein the interior step and retraction lip portion is found on the same side of the body
a first pressure relief opening formed in the body; and
a second pressure relief opening formed in the body; and
a tapered rib extending partially along the exterior surface from the stop to before the front end tapering from a high point adjacent to the stop to a low point before the front end with the tapered rib being on a side opposite to the retraction lip portion and between the first pressure relief opening and the second pressure relief opening; and wherein the retraction lip portion has an angled portion that extends below the exterior surface of the body.
8. The disposable dental aerosol device of claim 7 wherein the body is constructed of plastic.
9. The disposable dental aerosol device of claim 7 wherein the first pressure relief opening has a triangular shape.
10. The disposable dental aerosol device of claim 7 wherein the rear end has a barb that extends away from the exterior surface.
11. The disposable dental aerosol device of claim 7 wherein the second pressure relief opening has a triangular shape.
12. A disposable dental aerosol device comprises:
a body having an exterior surface and an interior surface, a front end having an angled opening having a retraction lip portion, a rear end having an opening and a circumferential shoulder stop on the exterior surface of the body, an exterior side of the exterior surface opposite to the retraction lip portion, and a lumen formed between the front end and the rear end;
a first pressure relief opening formed through the body from the exterior surface to the interior surface and on the exterior side opposite to the retraction lip portion;
a second pressure relief opening formed through the body from the exterior surface to the interior surface and on the exterior side opposite to the retraction lip portion;
an interior step within the lumen positioned at the rear end and adjacent to the stop and facing the front end to facilitate directing aerosol and other matter through the lumen and out the opening in the rear end;
the lumen having a continuous straight surface from the front end to the opening in the rear end and opposite the interior step, wherein the interior step and retraction lip portion is found on the same side; and
a tapered rib extending partially along the exterior surface from the stop to before the front end tapering from a high point adjacent to the stop to a low point before the front end with the tapered rib being on the exterior side opposite to the retraction lip portion and between the first pressure relief opening and the second pressure relief opening; and wherein the first pressure relief opening has a triangular shape.
13. The disposable dental aerosol device of claim 12 wherein the retraction lip portion has an angled portion that extends below the exterior surface of the body.
14. The disposable dental aerosol device of claim 12 wherein the rear end has a barb that extends away from the exterior surface.
15. The disposable dental aerosol device of claim 12 wherein the second pressure relief opening has a triangular shape.
