ENDOBRONCHIAL TUBE WITH INTEGRATED IMAGE SENSOR

摘要

An endobronchial tube comprising at least two lumens of different lengths for selectively associating with a patient about at least two locations relative to the Tracheal Carina. said tube comprising: a first lumen having an open distal end that associates proximally to the Carina within the Trachea, with a first inflatable cuff; a second lumen having an open distal end that extends distally, past the Carina and associates within one of the Left Bronchial branch and Right Bronchial branch with a second inflatable cuff; a dedicated image sensor lumen spanning the length of said first lumen, the dedicated image sensor lumen comprising an image sensor and illumination source disposed adjacent to the distal end of said first lumen, and configured to provide an image of the Tracheal bifurcation of the Tracheal Carina, the openings of the Left Bronchial branch, and the opening Right Bronchial branch; and at least one dedicated cleaning lumen disposed parallel with said dedicated image sensor lumen along the length of said endobronchial tube and wherein said cleaning lumen is configured to forms a cleaning nozzle at the distal end, wherein said cleaning nozzle is directed toward said image sensor lumen at its distal end.

1. An endobronchial tube having proximal and distal ends comprising:
a) a midline partition dividing said endobronchial tube into a tracheal ventilation tube and a bronchial ventilation tube, each having proximal and distal ends; wherein said tracheal ventilation tube and said bronchial ventilation tube are configured to have different lengths, wherein said bronchial ventilation tube extends beyond said tracheal ventilation tube such that said bronchial ventilation tube distal end is located distally to said tracheal ventilation tube distal end; b) a wall of said endobronchial tube; said wall comprising a plurality of channels formed within said wall, each channel having a proximal end adjacent to said endobronchial tube proximal end, said plurality of channels comprising an image sensor channel having a distal end adjacent to said tracheal ventilation tube distal end; a cleaning channel having a distal end adjacent to said tracheal ventilation tube distal end, a first inflating channel having a distal end adjacent to said tracheal ventilation tube distal end; and a second inflating channel having a distal end adjacent to said bronchial ventilation tube distal end; wherein the diameter of said image sensor channel is smaller at said proximal end and larger at said distal end of said image sensor channel; c) a flaring at the distal end of said tracheal ventilation tube; d) an image sensor and light source housed interior and adjacent to the distal end of said image sensor channel; wherein said light source is selected from the group consisting of at least one LED, optical fiber, waveguide, light guide, and any combination thereof; wherein said image sensor is selected from the group consisting of a CCD and CMOS image sensor; e) image sensor conducting wires and an image sensor connector, said image sensor conducting wires having a proximal end connected to said image sensor connector and a distal end connected to said image sensor and said light source such that said image sensor connector is electrically connected to said image sensor and said light source and is in image transfer data communication with said image sensor; f) an image sensor conducting wire notch, wherein the proximal end of said image sensor channel includes said image sensor conducting wire notch through which said image sensor conducting wires exit said image sensor channel; g) a cleaning nozzle in fluid communication with the distal end of said cleaning channel and proximal to said image sensor; wherein said nozzle is aimed such that fluid exits the nozzle towards the distal end of said image sensor and wherein said nozzle has an opening having a diameter from 0.1 mm to 2 mm; h) an inflatable tracheal cuff attached to said external wall of said endobronchial tube and positioned proximal to the distal end of said tracheal ventilation channel and in fluid communication with said first inflating channel; and i) an inflatable bronchial cuff attached to said external wall of said endobronchial tube and positioned proximal to the distal end of said bronchial ventilation channel and in fluid communication with said second inflating channel; wherein said endobronchial tube has a gauge from 26 Fr to 44 Fr; wherein said external wall of said endobronchial tube has a medial curvature adjustable from 100 degrees to 160 degrees; and wherein said external wall of said endobronchial tube has a left or right bronchial insertion compatible distal curvature; said distal curvature adjustable from 25 degrees to 70 degrees.
