TRACHEAL CANNULA

摘要

A tracheal cannula has an air supply and discharge breathing path between its base end to which a breathing tube extended from an external respirator is connected and its head end that is inserted in the trachea of a patient, and the head of the breathing path has a trachea side opening. A suction path for sucking phlegm collected in the trachea of the patient is provided separately from the breathing path, along the breathing path. That wall of the suction path which is on the trachea inner wall side has a phlegm suction opening facing the trachea inner wall, the phlegm suction opening being located in a region between the head of the suction path and a cuff.
