Abstract
The tracheostomy tube includes an elongate inner tube, an elongate insert, and an outer tube. The inner tube has a side wall with an outer surface having threads and a distal end of the inner tube defines an annular collar. The inner tube has a longitudinal slot extending through the side wall and the collar from the distal end to a proximal end of the inner tube. The insert is slidably mountable in the slot of the inner tube and collar. The outer tube has an inner surface with grooves formed therein to threadingly engage the threads of the inner tube to secure the tracheostomy tube to a neck of a patient.
