Abstract

A laryngoscope with a detachable camera, the system providing illuminating light to and images of the area ahead of the laryngoscope to facilitate insertion of the laryngoscope without damage to the surrounding tissue, the system including a keyed attaching device for facilitating attachment of camera and laryngoscope in a correct orientation.

Claims

1. A laryngoscope system comprising:

a handle having a cavity located therein and a first light and image guiding attachment;

a blade connected to said handle;

a camera detachably connectable to said handle and having a second light and image guiding attachment complementary to and engagable with the first light and image guiding attachment along a direction of movement;

said first light and image guiding attachment and said second light and image guiding attachment collectively including;

an image guiding stem, engagable along the direction of movement with an image guiding receptacle; and

a light guiding stem, engagable along the direction of movement with a light guiding receptacle.

2. The system according to claim 1 further comprising a light guide and an image guide located within said blade.

3. The system according to claim 2 wherein said light guide and said image guide are in communication with corresponding light and image guides located in said camera via the light and image guiding attachments.

4. The system according to claim 1 wherein said handle includes a camera locking mechanism for securing said camera in said handle.

5. The system according to claim 1 wherein said image guiding stem is larger in diameter and longer in length than said light guiding stem.

6. The system according to claim 1 wherein said blade is permanently attached to said handle.

7. The system according to claim 6 further comprising a light guide and an image guide located within said blade.

8. The system according to claim 7 wherein said light guide and said image guide are permanently located within said blade.

9. A method for attaching a camera to a handle of a laryngoscope comprising the steps of:

providing a cavity within the handle;

providing a light guiding stem and an image guiding stem on the handle;

positioning a camera within the cavity, the camera having a light guiding receptacle and an image guiding receptacle complementary to and engagable with the light guiding stem and the image guiding stem;

engaging the light guiding stem and the image guiding stem with the light guiding receptacle and the image guiding receptacle respectively along a direction of movement.

10. A laryngoscope system comprising:

a handle having a first light guide and first image guide located therein;

a first light and image guiding connector associated with said handle;

a blade connected to said handle;

a second light guide and a second image guide located in said blade;

a second light and image guiding connector associated with said blade, said second light and image guiding connector being complementary to and engagable with said first light and image guiding connector along a direction of movement.

11. The laryngoscope system according to claim 10 further comprising a camera located within said handle, said camera generating an image signal.

12. The laryngoscope system according to claim 10 further comprising a video screen coupled to said camera for display of the image signal.

13. The laryngoscope system according to claim 10 wherein said blade is disposable.

14. The laryngoscope system according to claim 10 further comprising a power source located in said handle.

15. The laryngoscope system according to claim 10 further comprising an illuminating light source located in said handle.

16. The laryngoscope system according to claim 10 further comprising a locking device for securing said blade to said handle.

17. The laryngoscope system according to claim 10 wherein said second light guide and said second image guide are non-removably mounted within said blade.

18. The laryngoscope system according to claim 10 wherein said first light guide and said first image guide are in communication with said second light guide and said second image guide respectively, via the first and second light and image guiding connectors when in an engaged position.
