Abstract: A medical device for internally maintaining by means of an oral adhesive composition an endotracheal tube in proper position in a patient's mouth and protecting the patient from endotracheal intubation associated injury, as well as subsequently permitting adjustment of the endotracheal tube relative to the device. The device has a heat-sensitive moldable polymer on its superior surface for adaptation to individual patient's oral cavities. The invention also prevents endotracheal tube occlusion from patient jaw closure, and is particularly well-adapted for patients suffering from facial burns, dermatitis, or cleft palate syndrome. A method of using the device is also disclosed.
