Endotracheal tube attachment system

An endotracheal tube interface apparatus comprising:

• a. an endotracheal tube having a tracheal end configured to be placed through an oral or nasal orifice of a patient into the trachea and an external oral end configured to remain outside the patient;
• b. an enclosed space structure defining an internal volume and having a rearward wall;
• c. a first hollow stem disposed on the rearward wall and having an inside diameter greater than an outside diameter of the endotracheal tube, the first hollow stem opening into the internal volume;
• d. a second hollow stem disposed on a surrounding wall of the enclosed space structure, the second hollow stem opening into the internal volume and having an inside diameter at least equal to an inside diameter of the endotracheal tube;
• e. a section of flex tubing disposed within the internal volume and attached at a first end to a fitting installed on the external oral end of the endotracheal tube and attached at a second end to the second hollow stem;
• f. a connector on the second hollow stem configured to couple to an external breathing-gas delivery tube;
• g. and a securing apparatus coupled to the enclosed space structure and configured to retain the enclosed space structure at a front portion of the patient;
• h. wherein the external oral end of the endotracheal tube extends through the first hollow stem into the internal volume and is fluidly connected via the flex tubing to the second hollow stem to receive breathing gas delivered through the external breathing-gas delivery tube, and wherein the flex tubing permits movement of the external oral end within the enclosed space structure while reducing transmission of forces to the tracheal end during relative movement of the endotracheal tube and the enclosed space structure.
