Abstract

An intubation guide for guiding, positioning and/or insertion of e.g. an endotracheal tube in a patients trachea, and where the intubation guide comprises a relatively flexible guide extending from the distal end of a relatively stiff positioning handle having a curved section between its distal and proximal end, wherein the guide element forms a scoop shaped guide in extension of the positioning handle, and in that the positioning handle comprises an intubation channel extending along the positioning handle, and having a first end near the proximal end of the positioning handle, and the other end at the distal end near the guide scoop.

First claim

The invention claimed is:

1. An intubation guide for positioning an endotracheal tube in a patient's trachea, the intubation guide comprising:
a positioning handle having a proximal end, a distal end, and a curved section therebetween, the positioning handle including a wedge portion and an intubation channel open on a concave side of the curved section, the concave side of the curved section of the positioning handle facing a patient's tongue when the intubation guide is inserted correctly in the patient, the intubation channel defined by a first flange, a second flange opposite the first flange, and a connecting portion connecting the first flange to the second flange, the connecting portion having an anterior surface adapted to guide insertion of the endotracheal tube into the patient; and
a guide element connected to and extending from the distal end of the positioning handle, the guide element including a flexible plate having an outer periphery and an inflated tube along the outer periphery of the plate, the flexible plate having an anterior surface that is substantially continuous with the anterior surface of the connecting portion, the wedge portion extending partially over the anterior surface of the flexible plate and configured to directly push the epiglottis of the patient aside when the guide element is slid behind or under the patient's epiglottis.

2. The intubation guide according to claim 1 , wherein the wedge portion has a wedge point pointing away from the positioning handle.

3. The intubation guide according to claim 1 , wherein the positioning handle comprises a second channel extending at least partly along the positioning handle and having a distal end at the distal end of the positioning handle.

4. The intubation guide according to claim 3 , wherein the second channel has an optical window closing the distal end of the second channel, and wherein the second channel and the optical window are arranged to allow an imaging device to be inserted into the second channel and be positioned to provide images of an area in front of the guide element when the intubation guide is correctly inserted in a patient.

5. The intubation guide according to claim 1 , wherein the positioning handle further comprises a second channel extending at least partly along the first flange and a third channel extending at least partly along the second flange and having an open end adjacent to the distal end of the positioning handle.

6. The intubation guide according to claim 1 , wherein the positioning handle comprises an extension from the proximal end of the positioning handle for gripping by an operator.

7. The intubation guide according to claim 1 , wherein the positioning handle is made from a hard plastic material, and the guide element is made from a soft plastic material, and where the guide element is attached to the positioning handle by gluing, welding or molding.

8. An intubation guide for positioning an endotracheal tube in a patient's trachea, where the intubation guide comprises:
a positioning handle having a proximal end, a distal end, and a curved section therebetween, the positioning handle comprising an intubation channel on a concave side thereof and a wedge portion, the intubation channel formed in part by a first flange arranged on one side of the intubation channel, a second flange arranged on an opposite side of the intubation channel, and a connecting portion connecting the first flange to the second flange, the connecting portion having an anterior surface adapted to guide insertion of the endotracheal tube into the patient, and the intubation channel extending from the proximal end to the distal end of the positioning handle and being open along its length between the first flange and the second flange; and
a guide element that is flexible and is connected to the connecting portion of the positioning handle opposite the first flange and the second flange, the guide element including a flexible plate having an outer periphery and an inflated tube along the outer periphery of the flexible plate, the flexible plate having an anterior surface that is substantially continuous with the anterior surface of the connecting portion,
wherein the positioning handle comprises a second channel adjacent the first flange and extending at least partly along the positioning handle, the second channel having a distal end adjacent the distal end of the positioning handle and a proximal end, and
wherein the wedge portion extends partially over the anterior surface of the flexible plate and is configured to directly push the epiglottis of the patient aside when the guide element is slid behind or under the patient's epiglottis.

9. The intubation guide according to claim 8 , wherein the first flange is on a patient's left-hand side when the intubation guide is inserted correctly in the patient.

10. The intubation guide according to claim 9 , wherein the wedge portion extends from the second flange.

11. The intubation guide according to claim 10 , wherein the second channel has an optical window enclosing the distal end of the second channel and configured to allow an imaging device to be inserted into the second channel through the proximal end of the second channel.

12. The intubation guide according to claim 11 , wherein the positioning handle further comprises a third channel adjacent to the second flange.

13. The intubation guide according to claim 8 , wherein the positioning handle further comprises an extension attached to the proximal end of the positioning handle for gripping by an operator.

14. The intubation guide according to claim 8 , wherein the positioning handle is made from a hard plastic material, the guide element is made from a soft plastic material, and the guide element is attached to the positioning handle by gluing, welding or molding.

15. An intubation guide for positioning an endotracheal tube in a patient's trachea, the intubation guide comprising:
a positioning handle having a proximal end, a distal end, and a curved section therebetween, the positioning handle including a wedge portion and an intubation channel open on a concave side of the curved section and formed in part by a first flange arranged on one side of the intubation channel, a second flange arranged on an opposite side of the intubation channel, and a connecting portion connecting the first flange to the second flange, the connecting portion having an anterior surface adapted to guide insertion of the endotracheal tube into the patient; and
a scoop shaped guide element comprising a plate having an outer periphery and a third flange extending from the first flange and the second flange and the outer periphery of the plate, wherein the plate is flexible and comprises an anterior surface that is substantially continuous with the anterior surface of the connecting portion,
wherein the wedge portion extends partially over the anterior surface of the flexible plate and is configured to directly push the epiglottis of the patient aside when the scoop shaped guide element is slid behind or under the patient's epiglottis.

16. The intubation guide according to claim 15 , wherein the positioning handle further comprises a second channel extending at least partly along the first flange and having a distal end coextensive with the distal end of the positioning handle.

17. The intubation guide according to claim 16 , wherein the second channel has an optical window enclosing the distal end of the second channel and configured to allow an imaging device to be inserted into the second channel through a proximal e
