Endotracheal tube having a beveled tip and orientation indicator
DCFirst Claim
1. An endotracheal tube for insertion into a patient'"'"'s upper airway, through the larynx, and into the trachea, said endotracheal tube comprising:
- a tubular member extending between a proximal end and a distal end having a posterior wall intended for insertion adjacent to the posterior portion of a patient'"'"'s trachea;
a beveled distal end on said tubular member forming a tip on said posterior wall of said tubular member, whereby the tip on the distal end of the tubular member passes through the posterior portion of the opening in a patient'"'"'s larynx as the endotracheal tube is advanced into a patient'"'"'s trachea; and
a visual indicator on said tubular member indicating the rotational orientation of said tip of said tubular member during insertion of the endotracheal tube along a patient'"'"'s airway.

Abstract
A method and apparatus for intubation of a patient'"'"'s airway uses an endotracheal tube having a beveled distal end with a tip on the posterior wall of the endotracheal tube, and a visual indicator extending along the endotracheal tube. For example, the visual indicator can be a radio-opaque stripe extending the length of the anterior and/or posterior wall of the endotracheal tube. To use the apparatus with the patient in a supine position, the healthcare provider first takes a position above the patient'"'"'s head. The distal end of the endotracheal tube is then inserted into the patient'"'"'s mouth so that the visual indicator remains visible to the healthcare provider when viewed from above. The healthcare provider advances the endotracheal tube into the patient'"'"'s airway while monitoring the position of the visual indicator to ensure that the tip at the distal end of the endotracheal tube passes through the midline of the wider posterior portion of the opening in the patient'"'"'s larynx.

-
a tubular member extending between a proximal end and a distal end having a posterior wall intended for insertion adjacent to the posterior portion of a patient'"'"'s trachea, and an opposing anterior wall;
a beveled distal end on said tubular member forming a tip on said posterior wall of said tubular member, whereby the tip on the distal end of the tubular member passes through the posterior portion of the opening in a patient'"'"'s larynx as the endotracheal tube is advanced into a patient'"'"'s trachea; and
a visible stripe extending from said proximal end to said distal end of said tubular member indicating the rotational orientation of said tip of said tubular member during insertion of the endotracheal tube along a patient'"'"'s airway. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method for intubating of a patient'"'"'s airway using an endotracheal tube having a beveled distal end with a tip on the posterior wall of the endotracheal tube, and a visual indicator extending along the endotracheal tube, said method comprising:
-
taking a position relative to the patient above the patient'"'"'s mouth;
inserting the distal end of the endotracheal tube into the patient'"'"'s mouth so that the visual indicator remains visible; and
advancing the endotracheal tube into the patient'"'"'s airway while monitoring the position of the visual indicator to ensure that the tip at the distal end of the endotracheal tube passes through the posterior portion of the opening in the patient'"'"'s larynx. - View Dependent Claims (16, 17)
