摘要:
The present invention concerns a tracheostomy cannula comprising a cannula tube, wherein the cannula tube has a bend with a radially inward and a radially outward side of the cannula tube and a tube lumen and a tube wall and an axis extending parallel to the tube wall in the tube lumen and a distal and a proximal end and on the radially outward side of the bend a first window region having one or more openings in the tube wall. To provide a tracheostomy cannula having a cannula tube, with which talking is made possible and the entry of air into the tissue is prevented even when the position of the tracheostomy cannula in the trachea or the anatomical conditions change, it is proposed in accordance with the invention that the cannula tube has in axially displaced relationship with the first window region at least one further window region having one or more openings in the tube wall.
