Endobronchial tube with integrated image sensor and a cleaning nozzle arrangement
An endobronchial tube which contains an integrated camera and light source and a cleaning nozzle arrangement disposed within dedicated peripheral lumen within the tube's wall.
1. An endobronchial tube comprising:
a tube having a wall;
a first lumen having a longitudinal portion and an open distal end;
a first inflatable cuff located proximally of the open distal end of the first lumen;
a second lumen having an open distal end;
a second inflatable cuff located distally of the first lumen;
a dedicated image sensor lumen in the wall comprising a circular cross-section at its distal end;
an image sensor adjacent an illumination source, the image sensor and the illumination source disposed entirely within the dedicated image sensor lumen at the distal end thereof and having a cross-section that fits entirely within the circular cross-section of the distal end of the dedicated image sensor lumen, within the wall of the tube; and
a dedicated cleaning nozzle arrangement wholly embedded in the wall of the tube, the dedicated cleaning nozzle arrangement comprising a longitudinal cleaning lumen disposed parallel with the dedicated image sensor lumen and angled portions fluidly coupled to and extending from the longitudinal cleaning lumen, each of the angled portions defining a cleaning nozzle consisting of an elongate aperture in the wall of the tube, connecting to and extending from the longitudinal cleaning lumen to an opening on a surface across a thickness of the wall, the surface being distal of the image sensor and substantially parallel to the longitudinal axis of the tube, thus the cleaning nozzles are arranged distally from the image sensor, wherein the cleaning nozzles comprise a first cleaning nozzle and a second cleaning nozzle, and whereby the dedicated cleaning nozzle arrangement is configured to flush a fluid through the cleaning nozzles to clear a field of view of the image sensor.
2. The endobronchial tube of claim 1 , wherein a diameter of the first cleaning nozzle is larger than a diameter of the second cleaning nozzle.
3. The endobronchial tube of claim 2 , wherein the diameter of the first cleaning nozzle is about 0.8 mm and the diameter of the second cleaning nozzle is about 0.6 mm.
4. The endobronchial tube of claim 1 , wherein the first cleaning nozzle and the second cleaning nozzle each have a diameter from about 0.1 mm to about 2 mm.
5. The endobronchial tube of claim 1 , wherein the second cleaning nozzle comprises a plurality of cleaning nozzles.
6. The endobronchial tube of claim 5 , wherein the plurality of cleaning nozzles are positioned distally of the first cleaning nozzle.
7. The endobronchial tube of claim 6 , wherein the plurality of cleaning nozzles are arranged in a linear fashion about a longitudinal axis of the cleaning lumen.
8. The endobronchial tube of claim 6 , wherein the plurality of cleaning nozzles are arranged in an arc.
9. The endobronchial tube of claim 1 , wherein the dedicated image sensor lumen is disposed within the wall of the tube between the first lumen and the second lumen.
10. The endobronchial tube of claim 1 , wherein the second lumen comprises a second image sensor.
11. The endobronchial tube of claim 1 , wherein the second inflatable cuff is located at a distal end of the endobronchial tube.
12. The endobronchial tube of claim 1 , wherein the second inflatable cuff is angled toward the longitudinal cleaning lumen.
13. The endobronchial tube of claim 12 , wherein the second inflatable cuff is dimensioned to be positioned in and to completely block either a right or left bronchus when inflated.
14. The endobronchial tube of claim 1 , wherein the image sensor lumen is configured to provide an image of a tracheal bifurcation of a Tracheal Carina, an opening of a Left Bronchial branch, or an opening of a Right Bronchial branch.
15. The endobronchial tube of claim 1 , wherein the cleaning nozzles are aimed proximally toward the image sensor to clear the field of view of the image sensor.
16. The endobronchial tube of claim 1 , wherein at least one of the angled portions of the dedicated cleaning lumen include an open end extending through a surface of a wall forming the image sensor lumen thereby defining its respective cleaning nozzle.
