Tracheostomy Tube

Abstract

There is provided an improved tracheostomy tube having a distal section that over-molds a proximal section. The distal section is desirably made from a more flexible polymer than the proximal section to reduce trauma should the distal section contact the tracheal wall. The insertion of the tracheal tube in the trachea results in large forces being exerted on the tube. Forces acting on the tube after installation can also be rather large. Over-molding of the proximal section by the distal section results in a stronger bond than if the parts are butt-welded. The sections are desirably made from the same polymer and are desirably substantially transparent or clear to visible light so that cameras or other observation means may be used to inspect the tracheal walls through the tracheostomy tube without removing it from the patient.
