Abstract

An oral suction device provides an oral suction screen over the oral cavity of a patient by providing upper and lower suction wings attached to a manifold. The wings are inserted between the upper and lower lips and arches of a patient, respectively, and serve to capture aerosols which would otherwise be ejected from the oral cavity. A tongue/cheek retractor, also in pneumatic communication with the manifold, serves to extract saliva and other products from the oral cavity while also preventing the tongue and cheeks from ingress of the workspace for the dental procedure.

Claims (7)

1. An oral suction device comprising:

a. a central manifold in pneumatic communication with a vacuum source;

b. a tongue retractor flap having suction ports, said suction ports in the tongue retractor flap in pneumatic communication with the central manifold;

c. a pair of parallel suction wings, mounted upon the central manifold, said parallel suction wings having a plurality of suction ports in pneumatic communication with the central manifold; and,

d. a bite block mounted upon the central manifold;

wherein the parallel suction wings and the suction ports thereon define a suction curtain positioned proximate an oral cavity when in use.

2. The oral suction device of claim 1 , further comprising an illumination source.
