Abstract
A medical device tube having opposing support ears for improved coupling of an inner cannula to an outer cannula. The medical device tube comprises an outer cannula having opposing support ears on an outer cannula connector flange attached to a proximal end of the outer cannula. The opposing support ears maintain locking ears of the inner cannula in substantially one position. The opposing support ears substantially prevent the locking ears in contact with the outer cannula connector flange from slipping therefrom by, e.g., rotation, axial displacement, torsional shear, etc.
Claims20
A tracheostomy tube outer cannula, comprising:
- a conduit;
- an outer cannula connector coupled to a proximal end of the conduit and having a locking flange and opposing support ears, wherein the opposing support ears are configured to receive locking ears of an inner cannula connector to prevent undesired movement of the inner cannula connector in relation to the outer cannula connector.
A tracheostomy tube outer cannula connector, comprising:
- a passageway configured to be coupled to a proximal end of an outer cannula of a tracheostomy tube;
- and
- a locking flange and opposing support ears coupled to the passageway, wherein the opposing support ears are configured to receive locking ears of an inner cannula connector to prevent undesired movement of the inner cannula connector in relation to the outer cannula connector.
A tracheostomy tube outer cannula connector, comprising:
- a passageway configured to be coupled to a proximal end of an outer cannula of a tracheostomy tube;
- a locking flange;
- a first support ear and a second support ear, wherein the first support ear and the second support ear oppose one another to form a partial annulus with a diameter that is larger than a diameter of the passageway and wherein the first support ear and the second support ear are configured to receive locking ears of an inner cannula connector to prevent undesired movement of the inner cannula connector in relation to the outer cannula connector.
