Abstract
Abstract The invention depicts an instrument for medical use which facilitates and simplifies elective or emergency endotracheal intubation, to be used when indicated for ventilatory support. The invention consists of a one piece instrument, inclusive of an upper handle portion and curved lower blade portion made of a hard plastic material, fully disposable if desired, which allows suction capabilities as well as direct visualization of the vocal cords and larynx for accurate endotracheal intubation. The endotracheal tube is preloaded into one of the bored chambers of the embodiment of the invention. In addition, a second port is available which may be connected at the top of the device to equipment for suctioning, eliminating the need for a suction catheter. Direct visualization of the vocal cords, larynx, and upper airways is accomplished through fiberoptic bundles which bring the images to an eyepiece at the top handle portion of the device. The endotracheal tube can be safely advanced from a close proximity to the upper airways, through the vocal cords, followed by inflation of the balloon located in the endotracheal tube cuff. The plastic intubator may be slipped in an upward direction over the endotracheal tube, removed, and discarded. The process of intubation is completed and accomplished under direct visualization of anatomical structures throughout the procedure. Benefits are increased rapidity, minimal trauma, accuracy, enhanced safety, and minimal operator training. Further eliminated are the trial and error characteristics of blind procedures.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
196 words
An intubation guide for the easy and accurate positioning of an endotrachael tube through the vocal cords of a patient being intubated, comprising: an upper handle portion; a lower blade portion joined to the upper handle portion for inserting into the patient's mouth; a plurality of spaced conduits longitudinally extending from the upper portion into the lower portion of said guide; one of the conduits being adapted to removeably receive the endotrachael tube therein, said conduit extending the entire length of said lower blade portion and penetrating a terminal edge of said lower blade portion; a second conduit being adapted to be connected to a suction source, said second conduit penetrating a terminal edge of said lower blade portion to remove fluids from within the patient's mouth; a third conduit being adapted to both receive a light source for illuminating the area into which the endotrachael tube is to be positioned and receive receiving images from the illuminated area, said third conduit terminating within said lower blade portion to prevent contact with the patient's bodily fluid; and an eyepiece positioned in the upper handle portion cooperatively connected to said third conduit for viewing the patient's throat.
Claim 2
Dependent Claim
196 words
An intubation guide for the easy and accurate positioning of an endotrachael tube through the vocal cords of a patient being intubated, comprising: an upper handle portion; a lower blade portion joined to the upper handle portion for inserting into the patient's mouth; a plurality of spaced conduits longitudinally extending from the upper portion into the lower portion of said guide; one of the conduits being adapted to removeably receive the endotrachael tube therein, said conduit extending the entire length of said lower blade portion and penetrating a terminal edge of said lower blade portion; a second conduit being adapted to be connected to a suction source, said second conduit penetrating a terminal edge of said lower blade portion to remove fluids from within the patient's mouth; a third conduit being adapted to both receive a light source for illuminating the area into which the endotrachael tube is to be positioned and receive receiving images from the illuminated area, said third conduit terminating within said lower blade portion to prevent contact with the patient's bodily fluid; and an eyepiece positioned in the upper handle portion cooperatively connected to said third conduit for viewing the patient's throat.
Claim 3
Dependent Claim
23 words
The intubation guide of claim 1 and further including a light source removeably positioned in said third conduit for illuminating the patient's throat.
Claim 4
Dependent Claim
9 words
The intubation guide of claim 1 formed of plastic.
Claim 5
Dependent Claim
48 words
The intubation guide of claim 3 wherein the first and third conduits are disposed at an acute angle with respect to each other at the distal portion whereby a tip of the endotracheal tube can be readily observed by the viewer as it is moved into operational position.
Claim 6
Dependent Claim
47 words
The intubation guide of claim 1 wherein the first and third conduits are disposed at an angle with respect to each other at the distal portion whereby a tip of the endotrachael tube can be readily observed by the viewer as it is moved into operational position.
Claim 7
Dependent Claim
46 words
The intubation guide of claim 1, wherein the third conduit includes a fiber optic bundle for transmitting light out of said lower blade portion and a fiber optic bundle for receiving and transmitting images to said eyepiece to enable the proper positioning of the endotrachael tube.
Claim 8
Dependent Claim
48 words
The intubation guide of claim 6 wherein the first and third conduits are disposed at an acute angle with respect to each other at the distal portion whereby a tip of the endotracheal tube can be readily observed by the viewer as it is moved into operational position.
Claim 9
Dependent Claim
18 words
The intubation guide of claim 6 wherein said fiber optic bundle is permanently positioned in said third conduit.
Claim 10
Dependent Claim
13 words
The intubation guide of claim 10 wherein said guide is formed of plastic.
Claim 11
Dependent Claim
48 words
The intubation guide of claim 9 wherein the first and third conduits are disposed at an acute angle with respect to each other at the distal portion, whereby a tip of the endotracheal tube can be readily observed by the viewer as it is moved into operational position.
Claim 12
Dependent Claim
23 words
The intubation guide of claim 10 and further including a light source removeably positioned in said third conduit for illuminating the patient's throat.
Claim 13
Dependent Claim
48 words
The intubation guide of claim 8 wherein the first and third conduits are disposed at an acute angle with respect to each other at the distal portion whereby a tip of the endotracheal tube can be readily observed by the viewer as it is moved into operational position.
Claim 14
Dependent Claim
39 words
The intubation guide of claim 6 wherein said fiber optic bundle terminates within the distal end of said guide, said distal end being made of transparent material to permit observation of the guide pathway via the fiber optic bundle.
Claim 15
Dependent Claim
48 words
The intubation guide of claim 13 wherein the first and third conduits are disposed at an acute angle with respect to each other at the distal portion whereby a tip of the endotracheal tube can be readily observed by the viewer as it is moved into operational position.
