US 2025/0359975 A1 · Oral Cavity Aerosol Trapping and Collection Ring and Mask

Abstract

A dental aerosol protection system for controlling dispersion of aerosol and splatter particles produced during dental procedures, the system including a ring assembly, a support mask for supporting the ring assembly on a patient, and a suction generating device, the ring assembly and support mask having suction ports which are connectable to the suction generating device to provide a negative suction force around the oral cavity, wherein the ring assembly and support mask can be connected or used separately to control dispersion of aerosols depending upon the requirements of the dental procedure, and one or more flexible extensions connectable to the ring assembly and support mask extending superiorly away from the patient around and over the oral cavity, the flexible extensions forming an adjustable physical barrier between the dental professional and the patient's oral cavity.

Dependent claims

A head-mountable face mask for containing oral aerosols and for protecting portions of a patient's face during dental procedures comprising:

an anterior surface;
a posterior surface contoured to conform to the face of the patient;
a forehead covering region adapted to directly engage with the patient's forehead;
a brow covering region;
an eye covering region;
a pair cheek covering regions cheek extending from the eye covering regions on opposite sides of the patient's nose and mouth and each having an inner margin, an outer margin, and a lower margin dimensioned to extend at or below the corner of the patient's mouth;
and
at least one suction nozzle coupled to at least one of the cheek covering regions, the suction nozzle having an outer end configured to be operably coupled to a suction generating device by a suction line, and an inner end forming a suction aperture directed to provide a suction force along an inner margin of the cheek covering region.

5 more elements

A ring assembly for limiting dispersion of aerosolized particles and splatter during dental procedures comprising:

a front surface;
a rear surface;
a frame portion dimensioned to extend circumferentially around the oral cavity of a patient;
a collar portion extending superiorly outwardly the frame portion;
a lip portion connected to the collar portion at a spaced apart location from the frame portion and having an inner edge defining a central opening in the ring assembly configured to be aligned with the patient's oral cavity;
a plurality of spaced-apart extension connectors joined to the ring assembly;
and
a suction port joined to the ring assembly having a suction nozzle forming a suction aperture on the ring assembly on one end, and another end operably couplable to a suction generating device for generating a suction force and creating a negative suction pressure circumferentially within the central opening for drawing potentially harmful aerosolized particles into the suction port.
