Abstract
A removable protective tip for placement over the outer end of a dental aspirator. The tip includes a cylindrical sleeve that frictionally fits over the walls of the aspirator end, and an integral open mesh screen extending across one end of the sleeve in a plane complementary to the outer edge of the aspirator. Side vents are provided immediately adjacent the screen. The tip prevents larger objects from being drawn into the aspirator assembly and also prevents the aspirator from grasping soft tissue in the mouth.

- one end of the sleeve being open;
- the remaining end of the sleeve being partially closed by a transverse open-mesh screen molded integrally with said sleeve, said screen being located in a plane complementary to the plane of the outer edges of the tube, said screen being recessed inwardly from the outer edge of the sleeve about its remaining end;
- and a plurality of open transverse vents formed through the sleeve immediately adjacent the screen, said vents being formed as inwardly directed notches through the outer edge of the sleeve and overlapping the outer surface of the screen.
