Abstract
Abstract An improved endotracheal tube is disclosed which provides for a more reliable and safer airway to a patient's lungs for the purpose of administering anesthesia, supplying oxygen and assisting a patient in breathing, and the like. The new and improved features of the tube make it easier for a health care professional to secure the tube to a patient's face, monitor its depth of insertion into the throat and assure its easy connection an disconnection from a medical or surgical apparatus. These improved features include flexible flanges molded to the tube, each of said flanges including a plurality of radially opposite slots to which adhesive tape is attached for securing said tube to a patient's face. The tube is also provided with colored rings, located between the upper and lower edges of each set of slots for monitoring the depth of insertion of the tube into the throat of a patient. A connection end of the tube is fitted with internal threads for threadedly engaging a universal connector for attachment to a medical or surgical apparatus.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
120 words
An endotracheal tube comprising: a tubular body portion having an inner surface, an outer surface, a length and a longitudinal axis, and said tubular body portion having an insertion end and a connection end; and a pair of flange means integral with said tubular body portion, said flange means extending from the exterior of said tubular body portion substantially in a plane which is substantially parallel to the longitudinal axis of the tubular body portion at said flange means, with a plurality of openings in said flange means, said openings being located at different locations along the length of the tubular body portion, for permitting the endotracheal tube to be fixed at a desired depth position within a patient's trachea.
Claim 2
Dependent Claim
120 words
An endotracheal tube comprising: a tubular body portion having an inner surface, an outer surface, a length and a longitudinal axis, and said tubular body portion having an insertion end and a connection end; and a pair of flange means integral with said tubular body portion, said flange means extending from the exterior of said tubular body portion substantially in a plane which is substantially parallel to the longitudinal axis of the tubular body portion at said flange means, with a plurality of openings in said flange means, said openings being located at different locations along the length of the tubular body portion, for permitting the endotracheal tube to be fixed at a desired depth position within a patient's trachea.
Claim 3
Dependent Claim
62 words
The endotracheal tube of claim 1 wherein each of said flanges comprises at least two radially extending portions which are connected by at least one longitudinally extending portion, which is substantially parallel to the axis of the tubular portion, said at least two radially extending portions and said at least one longitudinally extending portion defining one of said pluraity of openings therein.
Claim 4
Dependent Claim
36 words
The endotracheal tube of claim 2, wherein at least two radially extending flanges are provided on said body portion, such that each of said flanges is located on a radially opposite side of said body portion.
Claim 5
Dependent Claim
33 words
The endotracheal tube of claim 2, wherein at least four flanges are provided on said body portion, such that two flanges are located on each of radially opposite sides of said body portion.
Claim 6
Dependent Claim
33 words
The endotracheal tube of claim 2, wherein at least six flanges are provided on said body portion, such that three flanges are located on each of radially opposite sides of said body portion.
Claim 7
Dependent Claim
21 words
The endotracheal tube of claim 1, further comprising a plurality of internal threads located within said connection end of the tube.
Claim 8
Dependent Claim

The endotracheal tube of claim 6, further comprising a universal adaptor having a plurality of external threads at a connection end portion thereof, said universal adaptor threadably engaging said internal threads located at said connection end portion.
Claim 9
Dependent Claim
52 words
The endotracheal tube of claim 1, additionally comprising a plurality of ring markings around the tubular body portion in the region of the tubular body portion at which said flanges are located, each of said rings being circumferentially marked so as to be immediately visually distinguished from any other immediately adjacent ring.
Claim 10
Dependent Claim
27 words
The endotracheal tube of claim 8, wherein the immediately visually distinguishable circumferential markings are rings of different colors, no adjacent two of which are a similar color.

The endotracheal tube of claim 1, additionally comprising an adhesive tape member for holding the endotracheal tube at a desired fixed depth position within a patient's trachea, said adhesive tape member having two distinct portions of its length, a first of said length portions passing through an opening in one of said flanges and folded back along its length and securely adhered to its own length, and a second length portion for adhesion to the patient's face to fix the position of the tube within the patient's trachea.
Claim 12
Dependent Claim
55 words
The endotracheal tube of claim 10, wherein said first length portion of said adhesive tape member is of relatively narrow widths to facilitate passage thereof through an opening in one of said flanges, and said second length portion of said adhesive tape member is of relatively wide width to enhance adhesion to the patient's face.
Claim 13
Dependent Claim
22 words
The endotracheal tube of claim 11, wherein said adhesive tape member further comprises one adhesively sticky side having a removable coating thereon.
Claim 14
Dependent Claim
52 words
The endotracheal tube of claim 12, additionally comprising a plurality of ring markings around the tubular body portion in the region of the tubular body portion at which said flanges are located, each of said rings being circumferentially marked so as to be immediately visually distinguished from any other immediately adjacent ring.
Claim 15
Dependent Claim
27 words
The endotracheal tube of claim 13, wherein the immediately visually distinguishable circumferential markings are rings of different colors, no adjacent two of which are as similar color.
