摘要： A device, and method of using same, to evacuate aerosols generated proximate to teeth of a patient during dental procedures, including a central housing having a proximal end and a distal end. The proximal end defines a proximal housing opening and the distal end defines a distal housing opening having a first open area. The housing defines (i) at least one housing side port on each side of the housing and (ii) at least one internal passage in fluid communication with the distal housing opening, the proximal housing opening, and the housing side ports. The proximal end of the housing is shaped to be connectable to a conduit for a source of negative pressure. The device further includes a right-side cheek retractor and a left-side cheek retractor, each retractor defining a concave buccal-side surface, a convex oral-side surface, a retractor chamber, and at least a first arc of retractor openings (i) positioned along a portion of the oral-side surface, (ii) communicating with the retractor chamber, and (iii) having a first distribution of total open area along that retractor. A right-side arm extends between the housing and the right-side cheek retractor to support the right-side cheek retractor at a substantially fixed distance from the housing, and a left-side arm extends between the housing and the left-side cheek retractor to support the left-side cheek retractor at a substantially fixed distance from the housing. At least one right-side passageway connects one of the housing side ports with the retractor chamber of the right-side cheek retractor, and at least one left-side passageway connecting one of the housing side ports with the retractor chamber of the left-side cheek retractor.
