Abstract

An endotracheal tube placement system and method is provided including a placement-assistive handle, an oral anchor, a mechanized advancer, a video system, an endotracheal tube lock, an endotracheal tube manipulator, and an endotracheal tube stabilizer. The endotracheal tube is slipped over the endotracheal tube manipulator and is secured by the endotracheal tube lock. The placement-assistive handle houses the power supply, provides a foundation for attachment of other elements of the invention, and provides control of the tube placement. Attached to the handle is the mechanized advancer, which propels the endotracheal tube lock, endotracheal tube manipulator, and the endotracheal tube forward. The oral anchor comprises a bite block and mouth rest, and is attached to the ET supportive sheath-like ET stabilizer. The integrated video system comprises a video camera, a light source, and an LCD screen held by a swivel base.

Claims

1. An endotracheal tube placement system for use with an endotracheal tube by a clinician during intubation of a patient, comprising:

a placement-assistive handle configured for manual turning and grasping by said clinician;

an internal power source disposed within said placement-assistive handle;

a semi-malleable endotracheal tube manipulator perpendicularly attached to the inner end of said placement-assistive handle and configured to receive said endotracheal tube, wherein the manual turning of said placement-assistive handle guides the distal tip of said semi-malleable endotracheal tube manipulator to achieve motion in one or more planes along the x, y and z axis;

an endotracheal tube lock disposed at the proximal end of said endotracheal tube manipulator and configured to releasably secure said endotracheal tube to said endotracheal tube manipulator;

a video system powered by said internal power source and comprising a display screen, a video camera disposed at the distal end of said endotracheal tube manipulator, and a light source disposed at the distal end of said endotracheal tube manipulator, wherein said video system is operable to display an image obtained from said video camera on said display screen;

a mechanized advancer supported by said placement-assistive handle and configured to advance said endotracheal tube manipulator forward to lengthen the distance between the tip of said endotracheal tube manipulator and said placement-assistive handle; and

an advancement halting system, wherein said advancement halting system comprises a pressure sensor operatively connected to an advancement controller, wherein said pressure sensor is operative to sense the pressure at the distal end of said endotracheal tube manipulator and said advancement controller is operative to halt the advancement of said mechanized advancer upon receipt of an unsatisfactory reading from said pressure sensor.

2. The endotracheal tube placement system, as recited in claim 1, wherein said endotracheal tube manipulator is removably attachable to said placement-assistive handle.

3. The endotracheal tube placement system, as recited in claim 2, wherein said endotracheal tube manipulator is threadingly engageable with said placement-assistive handle.

4. The endotracheal tube placement system, as recited in claim 1, wherein said display screen is removably attachable to said placement-assistive handle.

5. The endotracheal tube placement system, as recited in claim 1, further comprising an endotracheal tube stabilizer supported by said placement-assistive handle, said endotracheal tube stabilizer forming a supportive sheath configured to receive said endotracheal tube manipulator.

6. The endotracheal tube placement system, as recited in claim 5, further comprising an oral anchor attached to said endotracheal tube stabilizer, said oral anchor comprising a bite block and a mouth rest.

7. The endotracheal tube placement system, as recited in claim 1, wherein said mechanized advancer is removably attachable to said placement-assistive handle.

8. The endotracheal tube placement system, as recited in claim 1, further comprising:

a stylet/tube articulator configured to apply pressure to a side of said endotracheal tube manipulator to increase the angle of said endotracheal tube manipulator; and

an articulation actuator disposed on said placement-assistive handle and configured to allow said clinician to manually activate said stylet/tube articulator.

9. The endotracheal tube placement system, as recited in claim 1, further comprising an advancer trigger operatively connected to said mechanized advancer and configured to be manually operated by said clinician.

10. A method to intubate a patient with an endotracheal tube, comprising:

placing said patient in the supine position;

opening said patient'"'"'s mouth;

retracting the tongue of said patient to expose the oropharynx;

placing an endotracheal tube with a distal cuff onto an endotracheal tube manipulator;

locking the proximal end of said endotracheal tube onto an endotracheal tube manipulator with a endotracheal tube lock;

grasping a placement-assistive handle perpendicularly connected to said endotracheal tube manipulator carrying said endotracheal tube;

introducing said endotracheal tube carried by said endotracheal tube manipulator into the mouth of said patient;

turning said placement-assistive handle to control the movement of the distal tip of said endotracheal tube manipulator to achieve motion in one or more planes along the x, y and z axis;

viewing a display screen providing indirect visualization of the distal tip of said endotracheal tube;

advancing said endotracheal tube manipulator carrying said endotracheal tube into the airway of said patient;

positioning said endotracheal tube manipulator carrying said endotracheal tube in the appropriate location in said airway of said patient;

inflating said endotracheal tube cuff;

unlocking said endotracheal tube from said endotracheal tube lock;

retracting said endotracheal tube manipulator from said endotracheal tube positioning an oral anchor onto said patient'"'"'s teeth; and

using said oral anchor as a stabilization point to facilitate the control of the movement of the distal tip of said endotracheal tube manipulator.

11. The method to intubate a patient with an endotracheal tube, as recited in claim 10, wherein turning said placement-assistive handle to control the movement of the distal tip of said endotracheal tube manipulator to achieve motion in one or more planes along the x, y and z axis comprises:

moving the wrist and hand to produce a movement along the x, y, or z axis to guide said endotracheal tube manipulator carrying said endotracheal tube; and

using a pushing movement to advance said endotracheal tube into the appropriate location in said airway of said patient.

12. The method to intubate a patient with an endotracheal tube, as recited in claim 10, wherein advancing said endotracheal tube manipulator carrying said endotracheal tube into the airway of said patient comprises pressing an advancer trigger to advance said endotracheal tube manipulator carrying said endotracheal tube through the mouth into the oropharynx of said patient and to the appropriate location in said airway of said patient.

13. The method to intubate a patient with an endotracheal tube, as recited in claim 10, wherein said display screen is attached to said placement-assistive handle.

14. The method to intubate a patient with an endotracheal tube, as recited in claim 10, wherein said display screen is remote from said placement-assistive handle.

15. The method to intubate a patient with an endotracheal tube, as recited in claim 10, wherein said placement-assistive handle is removably connected to said endotracheal tube manipulator.
