Abstract

A blind intubation guide (

10) includes a guide wall (

42), which aims an orotracheal tube (

120) into the laryngeal opening (

230), the guide wall (

42) being pivotally mounted to an aft member (

16) of the guide (

10) to accommodate throats (

202) of variable shallowness. The guide (

10) may also include a flexible spout (

100).

Description

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate an embodiment of the invention and, together with the general description of the invention given above and the detailed description of the embodiment given below, serve to explain the principles of the present invention.

FIG. 1 is a perspective view from the left of a blind intubation guide in accordance with the principles of the present invention;

FIG. 2 is an exploded, partial view of the guide of FIG. 1;

FIG. 3 is a partial, exploded view of the guide of FIG. 1 from the right;

FIGS. 4A and 4B are partial, right side elevation views of the guide of FIG. 1 showing a pivot action of the guide wall;

FIG. 5 is a schematic illustration, partially cut-away, showing the guide of FIG. 1 with the guide wall impacting the back of a shallow throat and with an orotracheal tube mounted thereto for purposes of explaining the principles of the present invention;

FIG. 6 is a view similar to FIG. 5 showing the guide wall pivoting and the spout flexing to accommodate the shallow throat as the guide is inserted deeper into the throat; and

FIG. 7 is a view similar to FIGS. 5 and 6 showing the guide in position after applying traction to the back of the tongue and with the orotracheal tube being advanced along the guide wall into the laryngeal opening.

Claims

1. An intubation guide comprising:

2. The intubation guide of claim 1 further comprising a side arm interconnecting the guide wall and aft member.

3. The intubation guide of claim 2, the side arm being rigidly connected to the guide wall and pivotally mounted to the aft member.

4. The intubation guide of claim 2, the side arm including a mounting post, the aft member including a post receiving channel, the mounting post being rotatably held in the post receiving channel whereby the guide wall pivots relative to the aft member by rotation of the mounting post in the post receiving channel.

5. The intubation guide of claim 2 further comprising cooperating stop structure associated with the aft member and the side arm, whereby to limit the extent of pivoting of the guide wall relative to the aft member.

6. The intubation guide of claim 5, the stop structure including a stop block socket formed on the aft member and a stop block formed on the arm.

7. The intubation guide of claim 5, the stop structure including a shoulder socket formed on the aft member and a shoulder formed on the arm.

8. The intubation guide of claim 1, the guide wall being pivotally mounted to the distal end of the aft member.

9. The intubation guide of claim 8, the guide wall being pivotally mounted to the support member.

10. The intubation guide of claim 1, the flexible spout being a separate piece mounted to the aft member.

11. The intubation guide of claim 1, the aft member being generally rigid, the flexible spout being formed integrally therewith.

12. The intubation guide of claim 1, the aft member including an extending handle portion.

13. An intubation guide comprising:

14. The intubation guide of claim 13, the side arm including a mounting post, the aft member including a post receiving channel, the mounting post being rotatably held in the post receiving channel whereby the guide wall pivots relative to the aft member by rotation of the mounting post in the post receiving channel.

15. The intubation guide of claim 13 further comprising cooperating stop structure on the aft member and the side arm, whereby to limit the extent of pivoting of the guide wall relative to the aft member.

16. The intubation guide of claim 15, the stop structure including a stop block socket formed on the aft member and a stop block formed on the arm.

17. The intubation guide of claim 15, the stop structure including a shoulder socket formed on the aft member and a shoulder formed on the arm.

18. The intubation guide of claim 13, the guide wall being pivotally mounted to the distal end of the aft member.

19. The intubation guide of claim 18, the guide wall being pivotally mounted to the support member.

20. The intubation guide of claim 13, the aft member including an extending handle portion.

21. The intubation guide of claim 13 further comprising a spout extending from the aft member and toward the guide wall.

22. An intubation guide comprising:

23. The intubation guide of claim 22, the flexible spout being a separate piece mounted to the aft member.

24. The intubation guide of claim 22, the aft member being generally rigid, the flexible spout being formed integrally therewith.

25. The intubation guide of claim 22, the aft member including an extending handle portion.

26. The intubation guide of claim 22 wherein the spout has a concave cross section.

27. A method of inserting an orotracheal tube into a laryngeal opening in a patient's throat comprising:

28. The method of claim 27 further comprising applying traction on the support member in cooperation with pivoting the guide wall back toward the first position whereby to increase the magnitude of the distance.

29. The method of claim 27 wherein the intubation guide includes a spout normally extending from the aft member towards the guide wall, the method including mounting the orotracheal tube so as to extend over the spout.

30. The method of claim 29 further comprising deforming the spout from a first form to a second form in cooperation with pivoting of the guide wall.

31. The method of claim 30 further comprising allowing the spout to flex back from the second form toward the first form in cooperation with applying traction on the support member.

32. The method of claim 31 further comprising applying traction on the support member in cooperation with pivoting the guide wall back toward the first position whereby to increase the magnitude of the distance.
