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 ### Claim 1 A laryngoscope, comprising: a curved blade comprising a proximal end, a distal end, and a first channel; a handle comprising a rotating part and a 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, such that the catalytic agent in the chemiluminescent light source is activated by the torsional pressure on the chemiluminescent light source 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 the distal end comprises a first channel terminal part and a second channel terminal part, separate from the first channel terminal part. ### Claim 2 (depends on 1) The laryngoscope of claim 1, wherein at least a part of the blade is reflective to the light. ### Claim 3 (depends on 1) The laryngoscope of claim 1, wherein the blade widens out from the proximal end to the distal end. ### Claim 4 (depends on 1) The laryngoscope of claim 1, wherein the blade comprises a lateral ridge configured to facilitate capture and direction of a tongue. ### Claim 5 (depends on 1) The laryngoscope of claim 1, wherein the first channel includes an optical fiber or a waveguide. ### Claim 6 (depends on 1) The laryngoscope of claim 1, wherein the handle comprises an enclosure in which the chemiluminescent light source resides. ### Claim 7 (depends on 6) The laryngoscope of claim 6, wherein the enclosure comprises an opening from which the chemiluminescent light source is inserted into the enclosure. ### Claim 8 (depends on 1) The laryngoscope of claim 1, wherein the handle comprises at least one connector configured to removably attach the blade to the handle. ### Claim 9 (depends on 8) The laryngoscope of claim 8, 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. ### Claim 10 (depends on 8) The laryngoscope of claim 8, 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. ### Claim 11 (depends on 1) The laryngoscope of claim 1, wherein the second channel traverses a length of the blade. ### Claim 12 (depends on 1) The laryngoscope of claim 1, wherein the second channel is proximate to the first channel. ### Claim 13 (depends on 1) The laryngoscope of claim 1, 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. ### Claim 14 A handle of a laryngoscope, comprising: a non-electric light source comprising a chemiluminescent light source, wherein a catalytic agent in the chemiluminescent light source is activated by pressure on the chemiluminescent light source to generate light; 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; and a rotating part configured to apply torsional pressure via a rotational cam to crack a vial of the catalytic agent in the chemiluminescent light source. ### Claim 15 (depends on 14) The handle of claim 14, wherein instead of a rotating part, the handle of the laryngoscope further comprises: a pressure activator configured to, when pressed, crack a vial of the catalytic agent in the chemiluminescent light source. ### Claim 16 (depends on 14) The handle of claim 14, wherein instead of a rotating part, the handle of the laryngoscope further comprises: a horizontal trigger configured to, when sliding, apply pressure via a cam to crack a vial of the catalytic agent in the chemiluminescent light source. ### Claim 17 A laryngoscope, comprising: a curved blade comprising a proximal end, a distal end, and a first channel; a handle comprising a pressure activator and a non-electric light source comprising a chemiluminescent light source, wherein the pressure activator is configured to, when pressed, crack a vial of a catalytic agent in the chemiluminescent light source to activate the chemiluminescent light source 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 the distal end comprises a first channel terminal part and a second channel terminal part, separate from the first channel terminal part. ### Claim 18 A laryngoscope, comprising: a curved blade comprising a proximal end, a distal end, and a first channel; a handle comprising a horizontal trigger and a non-electric light source comprising a chemiluminescent light source, wherein the horizontal trigger is configured to, when sliding, apply pressure via a cam to crack a vial of a catalytic agent in the chemiluminescent light source to activate the chemiluminescent light source to generate light that transmits along the first channel;
