Abstract
Airway assist device (AAD) is provided. The device includes an upper AAD component and a lower AAD component. The upper AAD component includes and upper tooth guide connected to an upper plate. The upper AAD component further includes an upper force receiving plate. The AAD also includes a lower AAD component. The lower AAD component includes a lower tooth guide connected to a lower plate. The lower AAD component further includes a lower force receiving plate. The upper and lower AAD components are connected in a way that allows relative movement between the two components between a neutral position and a plurality of extended positions to protrude and distract a patient's mandible. A ratchet mechanism inhibits movement of the lower plate from any extended position. The ratchet mechanism may be manually disengaged to allow the lower AAD component to return to the neutral position. The lower AAD component includes a chin guide. The chin guide includes a chin support member that is engageable with a patient's chin.
