Tracheostomy tube
First Claim
1. A tracheostomy tube for insertion into the trachea of a patient to support breathing, comprising:
- An outer cannula having a distal end for placement within the trachea and a proximal end for placement outside of the trachea;
a neck flange connected to the proximal end of said outer cannula for securing the tracheostomy tube to the patient;
inflatable sealing means near the distal end of said outer cannula for forming a seal with the tracheal walls;
a flexible inflation tube extending from within said sealing means and having a portion fixedly secured along the wall of said outer cannula near the proximal end of said outer cannula and said inflation tube further extending unsecured; and
means retaining a portion of said unsecured inflation tube at the proximal end of said outer cannula in longitudinal alignment with said secured portion, whereby any pulling force on said inflation tube proximal of said retaining means results is substantially only tensile force on the secured portion of said inflation tube.

Abstract
The specification discloses a tracheostomy tube which includes an outer cannula which has a tubular wall, a distal end for placement within the trachea of a patient and a proximal end for placement outside of the trachea. The outer cannula has an inflatable cuff attached near the distal end thereof for forming a seal with the tracheal wall. A flexible inflation tube extends from within the cuff and has a portion fixedly secured along the wall of the outer cannula to a point that is near, but not at, the proximal end of the outer cannula and further extends unsecured. An annular retaining collar, has a flange with an aperture in longitudinal alignment with the secured portion and which is adapted to receive the inflation tube, and is attached to the proximal end of the outer cannula. The unsecured inflation line is routed through the aperture and is thereby retained by the flange in the collar, whereby any force on the unsecured inflation tube proximal of the collar results in substantially only tensile forces being exerted on the junction of the unsecured portion and the fixedly secured portion of the inflation tube.

8. A tracheostomy tube for insertion into the trachea of a patient to support breathing, comprising:
-
an outer cannula having a tubular wall, a distal end for placement within the trachea and a proximal end for placement outside of the trachea; a neck flange connected to the proximal end of said outer cannula for securing the tracheostomy tube to the patient; an inflatable sealing means near the distal end of said out cannula for forming a seal with the tracheal wall; a flexible inflation tube extending from within said sealing means; said outer cannula having a longitudinal recess in the wall thereof adapted to receive said inflation tube; said inflation tube fixedly secured within said recess near the proximal end of said outer cannula, and said tube further extending unsecured; an annular retaining collar adapted to substantially surround and align a portion of said unsecured inflation tube at the proximal end of said outer cannula, whereby any pulling force on said inflation tube proximal of said retaining collar results in substantially only tensile forces on the secured portion of said inflation tube. - View Dependent Claims (9, 10, 11, 12, 13)
