Intubation devices and methods of use
Intubation devices and methods of intubating a patient are provided. The intubation devices include a laryngeal mask airway (LMA) component having a mask portion and a tube portion and an endotracheal tube (ETT) component positioned in the laryngeal mask airway (LMA) component having a translatable and/or rotatable endotracheal tube. The endotracheal tube can be translated and/or rotated by a manipulation rod extending through the laryngeal mask airway (LMA) component and mounted to the endotracheal tube (ETT). The intubation devices may include inflatable cuffs adapted to manipulate the positioning or orientation of the endotracheal tube and/or to seal openings about the endotracheal tubes. Various ports, passages, and conduits are provided to enhance the use and manipulation of the intubation device.
1. An intubation device comprising:
a laryngeal mask airway (LMA) component comprising a mask portion having an internal opening, and an elongated tube mounted to the mask portion, the elongated tube having an internal passageway in fluid communication with the internal opening of the mask portion;
a movable endotracheal tube (ETT) component comprising an elongated tube positioned and movable within the elongated tube of the LMA component;
an inflation cuff mounted to the elongated tube of the moveable ETT, the inflation cuff in fluid communication with an inflation lumen; and
a manipulation rod connected to the movable Eli component, the manipulation rod mounted for translation through a passage in the LMA component, and wherein at least a portion of the inflation lumen passes through the manipulation rod.
2. The intubation device as recited in claim 1 , wherein the inflation cuff is mounted adjacent a distal end of the elongated tube of the moveable ETT.
3. The intubation device as recited in claim 1 , wherein at least a portion of the inflation lumen is mounted on the elongated tube of the moveable ETT.
4. The intubation device as recited in claim 3 , wherein the at least the portion of the inflation lumen is molded into the elongated tube of the moveable ETT.
5. The intubation device as recited in claim 1 , wherein, when inflated, the inflation cuff restricts a flow of fluid through an annular passage defined by the elongated tube of the moveable ETT and a cavity into which the elongated tube of the moveable ETT is positioned.
6. The intubation device as recited in claim 1 , wherein the LMA component further comprises a proximal conduit positioned and adapted to communicate with a proximal end of the elongated tube of the movable ETT component.
7. The intubation device as recited in claim 6 , wherein the proximal conduit of the LMA is adapted to receive the proximal end of the elongated tube of the moveable ETT component.
8. The intubation device as recited in claim 6 , wherein the elongated tube further comprises a proximal portion opposite the mask portion, and wherein the proximal conduit is mounted within the proximal portion of the elongated tube.
9. The intubation device as recited in claim 8 , wherein the proximal conduit of the LMA component is mounted within the internal passageway of the LMA component.
10. The intubation device as recited in claim 6 , wherein the intubation device further comprises a sealing device between the proximal end of the elongated tube of the ETT component and the proximal conduit of the LMA component.
11. The intubation device as recited in claim 10 , wherein the sealing device is adapted to minimize leakage of fluid about engagement of the proximal end of ETT tube and the proximal conduit of the LMA component.
12. The intubation device as recited in claim 10 , wherein the sealing device is an elastomeric sealing device.
13. The intubation device as recited in claim 6 , wherein the proximal end of the ETT component is smaller than the proximal conduit of the LMA component.
14. The intubation device as recited in claim 13 , wherein the proximal end of the ETT component is smaller in diameter than the proximal conduit of the LMA component.
15. The intubation device as recited in claim 6 , wherein the proximal end of the ETT component is larger than the proximal conduit of the LMA component.
16. The intubation device as recited in claim 15 , wherein the proximal end of the ETT component is larger in diameter than the proximal conduit of the LMA component.
17. The intubation device as recited in claim 6 , wherein the proximal conduit positioned and adapted to communicate with the proximal end of the elongated tube of the movable ETT component comprises a tube having a distal end adapted to engage the proximal end of the movable ETT component.
18. The intubation device as recited in claim 17 , wherein the tube having the distal end adapted to engage the proximal end of the movable ETT component is sized to be received by the proximal end of the movable ETT component.
19. The intubation device as recited in claim 1 , wherein the elongated tube of the movable ETT component is prevented from being removed from the LMA component.
20. The intubation device as recited in claim 1 , wherein the LMA component further comprises a distal extension having a lumen.
21. The intubation device as recited in claim 20 , wherein the distal extension further comprises an orifice in fluid communication with the lumen.
22. The intubation device as recited in claim 1 , wherein the manipulation rod comprises a conduit, and wherein the at least the portion of the inflation lumen passes through the conduit.
