MULTI-LUMEN TRACHEAL TUBE WITH PRESSURE DISTRIBUTION

摘要

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.
