Devices and methods for intra-oral aerosol removal

An apparatus for removing aerosol and fluid substances from inside of a patient's mouth, the apparatus comprising:

• a sleeve comprising a first aperture on a proximal end of the sleeve and a second aperture on a distal end of the sleeve;
• an annular support ring coupled to the distal end of the sleeve on an edge of the second aperture and extending around the second aperture;
• a coupling comprising a proximal end and a distal end, the distal end of the coupling having a first port configured to couple to a suction tube, the coupling further comprising an interior cavity from the proximal end to the first port;
• a conduit having an interior cavity, the conduit coupled to the proximal end of the sleeve on an edge of the first aperture, the proximal end of the coupling connecting the interior cavity of the coupling to the interior cavity of the conduit, the conduit extending to form a circumferential boundary around an area that is sized to fit inside a patient's mouth;
• and
• openings arranged on a surface of the conduit, the openings forming a pathway for substances in the vicinity of the openings to enter the conduit, and the openings, the conduit, and the coupling forming a passageway through which substances can flow from the openings through the conduit and to the first port of the coupling for evacuating the substances from the patient's mouth,
• wherein the coupling is shaped so the distal end is positioned outside of an edge of the patient's mouth when the conduit is positioned inside the patient's mouth.
