Abstract: The present disclosure describes systems and methods that utilize a tracheal tube with a shaped evacuation port. An evacuation port coupled to a suction lumen may be shaped to reduce air channel formation within the suction lumen, which in turn may improve the suctioning force and efficiency. The shaped evacuation ports may be generally oval or may be shaped to minimize a height dimension while maintaining a suitable cross-sectional area. In particular embodiments, the shaped evacuation ports may have cross-sectional areas that correspond to a cross-sectional area of the suction lumen.

Abstract: The present disclosure describes systems and methods that utilize a tracheal tube with pressure distribution features. For certain patients, the vocal cords may form a seal with an inserted tracheal tube. A pressure distribution lumen may allow fluid communication between tracheal space above and below the vocal cords. This in turn may reduce the formation of a vacuum seal forming around a suction lumen evacuation port. Accordingly, the disclosed embodiments provide improved suctioning by distributing the pressure around the evacuation port and the space above the vocal cords.
