Abstract

A laryngoscope includes an arm and a handle. The arm is configurable between at least a first and a second position. A first blade sheath secures over the arm in the first position and a second blade sheath secures over the arm in the second position. A method of configuring a laryngoscope includes configuring a laryngoscope arm into a first position or a second position and securing a selected blade sheath to the arm.

Claims (54)

1. A laryngoscope comprising:

a handle;

a first arm component having a proximal end and a distal end opposed from the proximal end, the first arm component being substantially rigid;

a second arm component having a proximal end and a distal end opposed from the proximal end, the second arm component being substantially rigid;

a camera disposed at the distal end of the second arm component;

an intermediate arm component that movably connects the distal end of the first arm component to the proximal end of the second arm component; and

a hinge pivotably connecting the handle to the proximal end of the first arm component, the first arm component and the handle being pivotable about the hinge between a first position and a second position;

wherein when the hinge is in the first position, an angle formed between the first arm component and the handle is generally perpendicular and when the hinge is in the second position, the angle formed between the first arm component and the handle is generally obtuse.

2. The laryngoscope of claim 1 , further comprising:

a plurality of disposable blades, each of the plurality of blades comprising:

an open end configured to coaxially receive the first and second arm components;

an elongated end opposite the open end, the elongated end extending past the distal end of the second arm component; and

a window configured to align with the camera when the first and second arm components are coaxially received within the open end.

3. The laryngoscope of claim 2 , wherein at least one of the plurality of blades comprises a flat geometry and is configured to coaxially receive the first and second arm components when the hinge is in the first position.

4. The laryngoscope of claim 3 , wherein the at least one of the plurality of blades is a Miller blade.

5. The laryngoscope of claim 3 , wherein the at least one of the plurality of blades is a Macintosh blade.

6. The laryngoscope of claim 2 , wherein at least one of the plurality of blades comprises a curved geometry.

7. The laryngoscope of claim 2 , wherein the window extends away from the elongated end at an angle of at least 90 degrees.

8. The laryngoscope of claim 1 , further comprising a lock configured about the hinge to releasably lock the hinge in the first position or the second position.

9. The laryngoscope of claim 8 , wherein the first arm component and the handle are pivotable about the hinge to a plurality of positions between the first position and the second position, and the lock releasably locks the first arm component and the handle in the plurality of positions.

10. The laryngoscope of claim 9 , wherein the first arm component is pivotable about the hinge while the laryngoscope is in use.

11. The laryngoscope of claim 1 , further comprising a light source disposed at the distal end of the second arm component.

12. The laryngoscope of claim 1 , wherein when the hinge is in the first position, an angle between the first arm component and the handle is between 90 degrees and 130 degrees.

13. The laryngoscope of claim 1 , wherein when the hinge is in the second position, an angle between the first arm component and the handle is between 130 degrees and 170 degrees.

14. The laryngoscope of claim 1 , wherein an angle between the second arm component and the handle is about 90 degrees or less.

15. The laryngoscope of claim 14 , wherein the hinge and the intermediate arm component move in unison when the hinge moves from the first position to the second position, such that the angle between the second arm component and the handle is maintained between the first position and the second position.

16. A method of configuring a laryngoscope prior to a laryngoscopy, the method comprising:

providing a laryngoscope structure including a handle, a hinge connected to the handle, a first arm component pivotably connected to the hinge and a second arm component pivotably connected to the first arm component;

securing the handle within a handle sheath;

pivoting the first arm component about the hinge between a first position and a second position, wherein the first position establishes a generally perpendicular geometry between the first arm component and the handle and wherein the second position establishes a generally obtuse geometry between the first arm component and the handle; and

securing a blade sheath, selected from a plurality of blade sheaths based upon an identified laryngoscopy procedure to be performed, over the first arm component, second arm component, and the hinge, wherein the selected blade sheath engages the handle sheath in a fluid seal engagement;

wherein if the identified laryngoscopy procedure is a direct laryngoscopy, the first arm component is pivoted into the first position and a substantially flat blade sheath is selected from the plurality of blade sheaths and if the identified laryngoscopy procedure is an indirect laryngoscopy, the first arm component is pivoted into the second position and a substantially curved blade sheath is selected from the plurality of blade sheaths.

17. The method of claim 16 , wherein the laryngoscope structure includes a camera and a light source disposed at a distal end of the second arm component, further comprising:

recording image data with the camera;

presenting the image data on a graphical display communicatively connected to the camera.

18. The method of claim 17 , wherein the laryngoscope structure further comprises an intermediate arm component that pivotably connects the first arm component to the second arm component, further comprising:

pivoting the second arm component about the intermediate component with respect to the first component;

releasably locking the first arm component in the first position;

releasably locking the second arm component at a first predetermined angle with respect to the first arm component;

wherein the locked first arm component and the locked second arm component form a substantially rigid arm structure.

19. The method of claim 18 , further comprising:

releasably locking the first arm component in the second position;

releasably locking the second arm component at a second predetermined angle with respect to the first arm component;

wherein the locked first arm component and the locked second arm component form a substantially rigid arm structure.

20. A laryngoscope comprising:

a substantially rigid handle defining an open interior;

a power source housed within the open interior of the substantially rigid handle;

a first arm component having a proximal end and a distal end opposed from the proximal end, the first arm component being substantially rigid;

a second arm component having a proximal end and a distal end opposed from the proximal end, the second arm component being substantially rigid;

an intermediate arm component that movably connects the distal end of the first arm component to the proximal end of the second arm component;

a hinge that pivotably connects the handle to the proximal end of the first arm component, the first arm component being pivotable about the hinge between a first position and a second position;

a camera disposed at the distal end of the second arm component, the camera electronically coupled to the power source;

a light source disposed at the distal end of the second arm component, the light source electronically coupled to the power source; and

a removable blade sheath configured with an open interior for receiving the second arm component, intermediate arm component, first arm component, and hinge, the removable blade sealingly engages the substantially rigid handle to form a fluid impervious seal connecting the open interiors of the substantially rigid handle and the removable blade sheath.
