Abstract: A tracheal tube apparatus includes a cannula having first and second ends. An inflatable cuff is formed on the cannula between the first and second ends. A conduit extends from the cuff for introducing an inflating fluid into the cuff when it is desired to inflate the cuff and removing inflating fluid from the cuff when it is desired to deflate the cuff. A gauge for indicating the inflation pressure of the cuff is coupled in the conduit.

Abstract: A tracheotomy tube apparatus includes an outer cannula having first and second ends, a fenestration along the length of the outer cannula between the first and second ends, and a first inner cannula sized for insertion into the outer cannula. The first inner cannula includes a resilient region which lies adjacent the fenestration when the first inner cannula is properly oriented within the outer cannula, and a valve operatively associated with the first inner cannula. A region between the resilient region and the valve provides a passageway between the first inner cannula and the outer cannula when the first inner cannula is properly oriented within the outer cannula.

Abstract: A tracheotomy tube apparatus includes an outer cannula having first and second ends, and a fenestration along the length of the outer cannula between the first and second ends. The apparatus further includes a first inner cannula sized for insertion into the outer cannula. The first inner cannula has a raised region substantially to close the fenestration when the first inner cannula is inserted into the outer cannula. The apparatus further comprises a second inner cannula for insertion into the outer cannula when the first inner cannula is removed therefrom. The second inner cannula includes a resilient region which lies adjacent the fenestration when the second inner cannula is properly oriented within the outer cannula, a valve at an end thereof and a region between the resilient region and the end thereof which provides a passageway between the second inner cannula and the outer cannula when the second inner cannula is properly oriented within the outer cannula.
