ABSTRACT:
Method and apparatus are disclosed for replacing an endotracheal tube. The apparatus comprises an endotracheal tube obturator having an air passageway therein and a removable connector positioned at the proximal end of the obturator tube for ventilating the patient during replacement of the endotracheal tube. The obturator tube also includes a plurality of side ports for further ventilating the patient should mucous block the distal end of the obturator tube passageway. The removable connector includes a ventilator fitting and a removable and lockable obturator tube fitting joined thereto. The obturator tube fitting includes a sleeve having a plurality of flexible members for grasping the proximal end of the obturator tube. Extending into the passageway of the sleeve is a projection from the members for engaging the outside surface of the obturator tube when inserted in the passageway. A collar is slideably positionable about the sleeve between two retaining flanges for engaging a cam surface positioned on the flexible members for forcing the projections into the outside surface of the obturator tube. The apparatus is inserted into a placed endotracheal tube for ventilating the patient while the endotracheal tube is replaced. The quick removal connector permits the timely replacement of the endotracheal tube while maintaining ventilation of the patient.
