摘要

The present invention relates to an endotracheal or tracheostomy cannulas having for supplying and transporting a central lumen (2) for tidal air. Pipe includes hereafter: an inflatable seal cuff (3) of circular tube (1); For supplying compressed air to a pipe of cuff (3); It is located at or in a suction tube (6) for cuff (3) and terminal in the outside of pipe (1); One feed pipe (7), in the outside of pipe (1) also on cuff (3) and end. The present invention is directed to create an endotracheal or tracheostomy cannula, it ensures safe tracheal aspiration, which even viscous mucus or bigger mucus block there is, may accumulate in a patient's trachea and entangle on sealing element, can reliably have been aspirated. For this purpose, the wall (9) of pipe (1) has an open section (11) thickened along a part on its periphery, hollow interior space forms suction tube.
