Abstract
A 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.
Claims18
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.
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.
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.
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;
- 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.
