TRACHEAL STOMA DILATION APPARATUS AND METHOD OF MANUFACTURE
A tracheal dilator system and method of manufacture are provided, suitable for dilating a passageway into a patient airway. In one embodiment, a tracheal tube is provided. The tracheal tube includes a dilator retrieval tip disposed on a distal end of a tracheal tube cannula. The dilator retrieval tip is configured to retrieve a tracheal dilator configured to enter through the distal end of the tracheal tube and exit through a proximal end of the tracheal tube.
1 . A tracheal intubation system comprising:
a tracheal tube having a dilator retrieval tip disposed on a distal end of a tracheal tube cannula, wherein the dilator retrieval tip is configured to retrieve a tracheal dilator configured to enter through the distal end of the tracheal tube and exit through a proximal end of the tracheal tube.
2 . The system of claim 1 , wherein the dilator retrieval tip comprises a generally convex portion.
3 . The system of claim 2 , wherein the generally convex portion comprises a generally astroid shape, a generally elliptical shape, a generally circular shape, or a combination thereof.
4 . The system of claim 1 , wherein the dilator retrieval tip comprises a generally conical portion having a first angle α and a second angle β.
5 . The system of claim 4 , wherein first angle α comprises an angle between approximately 10° and 80°.
6 . The system of claim 4 , wherein the second angle β comprises and angle between approximately 100° and 170°.
7 . The system of claim 1 , wherein a distal end of the dilator retrieval tip comprises a rounded edge.
8 . The system of claim 1 , wherein the tracheal dilator comprises a reverse tracheal dilator configured to dilate a tracheal passageway leading into an airway from inside the airway.
9 . The system of claim 1 , wherein the tracheal dilator comprises a forward tracheal dilator configured to dilate a tracheal passageway leading into an airway from outside the airway.
10 . The system of claim 1 , wherein the tracheal dilator comprises a shaft and an expandable portion attached to the shaft, the expandable portion being configured to expand and contract, and wherein the shaft comprises an outer diameter smaller than an inner diameter of the tracheal tube cannula.
11 . A tracheal tube comprising:
a cannula configured to be disposed inside of a trachea; and
a dilator retrieval tip having a first portion configured to retrieve a tracheal dilator configured to enter through a distal end of the cannula and exit through a proximal end of the cannula.
12 . The tracheal tube of claim 11 , wherein the first portion comprises a generally convex portion.
13 . The tracheal tube of claim 12 , wherein the generally convex portion comprises a generally astroid shape, a generally elliptical shape, a generally circular shape, or a combination thereof.
14 . The tracheal tube of claim 11 , wherein the first portion comprises an approximately conical portion having a first angle α and a second angle β.
15 . The tracheal tube of claim 14 , wherein first angle α comprises an angle between approximately 10° and 80°.
16 . The tracheal tube of claim 14 , wherein the second angle β comprises and angle between approximately 100° and 170°.
17 . The tracheal tube of claim 11 , wherein the dilator retrieval tip comprises a second portion distal of the first portion and having a rounded edge.
18 . A method for manufacturing a tracheal tube comprising:
forming a cannula having a dilator retrieval tip on a distal end of the cannula, wherein the dilator retrieval tip comprises a portion configured to retrieve a tracheal dilator adapted to enter through the distal end of the tracheal tube and exit through a proximal end of the tracheal tube.
19 . The method of claim 18 , wherein the portion comprises a generally convex portion having a generally astroid shape, a generally elliptical shape, a generally circular shape, or a combination thereof.
20 . The method of claim 18 , wherein the portion comprises a generally conical opening having first angle and second unequal cone angles.
