Abstract

An endotracheal intubation device is disclosed for manipulating the lower end of an endotracheal tube into the trachea or windpipe by magnetically displacing the tip of the tube to direct it towards the trachea as the tube is lowered down a patient'"'"'s throat.

Claims

1. An endotracheal intubation device comprising:

a. a flexible non-metallic tubular member with an open end tapered for insertion into a patient'"'"'s trachea,

b. flexible means embedded in the wall of the tapered end of said tubular member for rendering said end magnetically responsive; and

c. a magnetic device externally positionable over the throat of said patient proximate to the tracheal orifice and adapted to displace said magnetically responsive end forward over the tracheal orifice as said tubular member is inserted through said patient'"'"'s throat.

2. The apparatus of claim 1 wherein said flexible means is a magnetically responsive elongated member helically embedded in said tube proximate said tip.

3. The apparatus of claim 1 wherein said flexible means comprises a ferromagnetic metal strip embedded longitudinally in said tip end of said tubular member to permit transverse movement of said tip in response to said external magnetic deivce.

4. The apparatus of claim 1 wherein said magnetic device is an electromagnet.

6. The apparatus of claim 1 wherein said tapered end is impregnated with a ferrogmagnetic material in granulated powder form.

7. The apparatus of claim 1 wherein said flexible means comprises a plurality of spaced apart ferromagnetic rings proximate the tip of said tubular member.

8. The apparatus of claim 1 wherein said flexible means is embedded in said tip end by affixing said flexible means into said tip and covering said affixed flexible means with a layer of flexible non-metallic material.

9. The apparatus of claim 1 wherein said means for rendering said end magnetically responsive is a removable ferromagnetic plug positionable in said tubular member proximate said tip.

5. The apparatus of cliam 1, including means for holding said external magnetic device in position anteriorly of said throat.
