Multi-lumen tracheal tube with visualization device
The present disclosure describes systems and methods that utilize a multi-lumen tube with an integral visualization apparatus, such as a camera. The multi-lumen tracheal tube system may include a camera apparatus that is positioned to facilitate left or right bronchial intubation. In addition, the camera apparatus may be a unitary assembly that functions to hold and position the camera relative to the tube and provides an acceptable profile for comfortable intubation. The camera apparatus may include additional components, such as integral light sources and flushing or cleaning devices to remove any buildup from the camera or optical components.
1. A tracheal tube, comprising:
a first ventilation lumen having a first distal end and a first proximal end and configured to be coupled to a ventilator;
a second ventilation lumen adjacent to the first lumen, the second lumen having a second distal end and a second proximal end configured to be coupled to the ventilator, wherein the second ventilation lumen is longer than the first ventilation, wherein the first and second proximal ends co-terminate, and wherein the second distal end is aligned with an upper bronchus of a patient when inserted;
an opening in a wall of a distal region of the second ventilation lumen, wherein the opening is proximal to the second distal end; and
a camera attached to the wall of the second ventilation lumen at a location substantially circumferentially opposite the opening, wherein a field of view of the camera is substantially through the opening.
2. The tracheal tube of claim 1 , wherein the camera is disposed within a substantially annular collar.
3. The tracheal tube of claim 1 , wherein the tracheal tube comprises a right-stem endobronchial tube.
4. The tracheal tube of claim 1 , wherein the camera is embedded in the wall of the second ventilation lumen.
5. The tracheal tube of claim 1 , comprising one or more light emitting diodes disposed proximate to the camera.
6. The tracheal tube of claim 1 , comprising a first cuff disposed around the first ventilation lumen and the second ventilation lumen, and a second cuff disposed around only the second ventilation lumen.
7. The tracheal tube of claim 6 , wherein the camera is below the first cuff and the second cuff.
8. The tracheal tube of claim 6 , comprising a first inflation lumen associated with the first cuff and a second inflation lumen associated with the second cuff.
9. The tracheal tube of claim 6 , wherein the second cuff comprise an S-shape.
10. The tracheal tube of claim 1 , wherein the first distal end is located on the tracheal tube between a first cuff and a second cuff.
11. The tracheal tube of claim 1 , wherein the tracheal tube is configured to be coupled to at least one of a ventilator, a bag for ventilation, inspiration valving, expiration valving, or an air supply.
12. The tracheal tube of claim 1 , comprising a suction lumen terminating in a port located proximal to a first cuff.
13. The tracheal tube of claim 1 , comprising a fluid delivery lumen associated with the camera, wherein the fluid delivery lumen is configured to supply fluid to a surface of the camera and remove buildup on the camera.
14. The tracheal tube of claim 1 , wherein the camera is located on an interior surface of the second ventilation lumen.
15. The tracheal tube of claim 1 , wherein the opening comprises a fenestration on a side wall of the second lumen.
16. The tracheal tube of claim 1 , wherein the camera is disposed on a wall that at least in part comprises a dividing wall between the first ventilation lumen and the second ventilation lumen along its length.
17. The tracheal tube of claim 1 , wherein an orientation of the camera is orthogonal to an airflow direction through the second ventilation lumen.
