A tracheal tube includes an airway tubular body (31), an inflatable cuff (41) disposed on the airway tubular body (31), a suction conduit (5) extending along the airway tubular body to terminate at a suction opening (52), and a guiding unit (30) disposed on the airway tubular body (31) and adjacent to the suction opening (52) . The guiding unit (30) includes at least one guiding member (301) having a plurality of ribs (302). Each two adjacent ones of the ribs (302) define a guiding groove (303) that extends toward the suction opening (52) and that terminates at a confluent region (304) in fluid communication with the suction opening (52) so as to guide secretions in the trachea (801) to the suction opening (52). |
