Abstract
An endotracheal tube assembly is disclosed. The endotracheal tube assembly includes an elongate tube having an outer wall, and a first connector disposed on the outer wall. The outer wall defines a generally cylindrical elongate central lumen therein, an elongate suction lumen therein, and a first suction lumen aperture therethrough, the first suction lumen aperture being in fluid communication with the elongate suction lumen. The first connector includes a first annular wall disposed within a second annular wall, where the first annular wall and the second annular wall extend away from a longitudinal axis of the elongate tube in a radial direction. An internal surface of the first annular wall defines a first flow passage, and a rim of the first annular wall defines a first connection aperture. The first connection aperture is in fluid communication with the elongate suction lumen through the first flow passage.
