Abstract

laryngoscope includes a curved blade including a proximal end, a distal end, and a first channel. The laryngoscope also includes a handle and a second channel. The handle includes a non-electric light source, e.g., a chemiluminescent light source. A catalytic agent in the chemiluminescent light source is activated by pressure on the chemiluminescent light source to generate light that transmits along the first channel. The second channel is disposed proximate and through the blade and configured to provide at least one of oxygen, suction, and an instrumentation into the proximal end and out of the distal end of the blade.

Claims (19)

1. A laryngoscope, comprising: a curved blade comprising a proximal end, a distal end, and a first channel; a handle comprising a non-electric light source and a rotating part, the non-electric light source comprising a chemiluminescent light source, wherein the rotating part is configured to apply torsional pressure via a rotational cam to crack a vial of a catalytic agent in the chemiluminescent light source, and the catalytic agent in the chemiluminescent light source is activated by the rotating part to generate light that transmits along the first channel; and a second channel disposed proximate and through the blade and configured to provide at least one of oxygen, suction, and an instrumentation into the proximal end and out of the distal end of the blade, wherein at least a part of the curved blade is reflective to the light generated by the chemiluminescent light source
2. The laryngoscope of claim 1, wherein the curved blade comprises two conduit structures, wherein the first channel comprises one of said conduit structures and the second channel comprises the other of said conduit structures.
3. The laryngoscope of claims 1 or 2, wherein the blade widens out from the proximal end to the distal end.
4. The laryngoscope of any one of claims 1 to 3, wherein the blade comprises a lateral ridge configured to facilitate capture and direction of a tongue.
5. The laryngoscope of any one of claims 1 to 4, wherein the first channel includes an optical fiber or a waveguide.
6. The laryngoscope of any one of claims 1 to 5, wherein the handle comprises an enclosure in which the chemiluminescent light source resides.
7. The laryngoscope of claim 6, wherein the enclosure comprises an opening from which the chemiluminescent light source is inserted into the enclosure.
8. The laryngoscope of any one of claims 1 to 7, wherein the catalytic agent in the chemiluminescent light source is activated prior to the chemiluminescent light source being inserted into the handle.
9. The laryngoscope of any one of claims 1 to 8, wherein a wavelength of the light is in a range of infrared to visible light.
10. The laryngoscope of any one of claims 1 to 9, wherein the handle comprises at least one connector configured to removably attach the blade to the handle.
11. The laryngoscope of claim 10, wherein the at least one connector comprises an optical interface configured to couple the light generated by the chemiluminescent light source to the first channel.
12. The laryngoscope of claims 10 or 11, wherein the at least one connector comprises an adaptor configured to couple at least one of an oxygen source, a suction source, and the instrumentation to the second channel.
13. The laryngoscope of any one of claims 1 to 12, wherein the second channel traverses a length of the blade.
14. The laryngoscope of any one of claims 1 to 13, wherein the second channel is proximate to the first channel.
15. The laryngoscope of any one of claims 1 to 14, wherein the instrumentation includes a wire, a cautery device, a laser, a fiber optics, a biopsy forceps, placement of radiotherapeutic markers and materials, a wire guided scalpel, and placement of topical medications and therapies.
16. A handle of a laryngoscope, comprising: a non-electric light source comprising a chemiluminescent light source; a rotating part configured to apply torsional pressure via a rotational cam to crack a vial of a catalytic agent in the chemiluminescent light source, wherein a catalytic agent in the chemiluminescent light source is activated by the rotating part to generate light; and a connector configured to removably attach a blade to the handle, wherein the connector comprises an optical interface configured to couple the light generated by the chemiluminescent light source to a light channel on the blade.
17. The handle of claim 16, comprising an enclosure in which the chemiluminescent light source resides.
18. The handle of claim 17, wherein the enclosure comprises an opening from which the chemiluminescent light source is inserted into the enclosure.
19. The handle of any one of claims 16 to 18, wherein the catalytic agent in the chemiluminescent cartridge is activated prior to the chemiluminescent light source being inserted into the handle.
