Laryngoscope and methods of use
A laryngoscope includes a handle having an inner cavity configured to accept at least part of a syringe, the handle having (a) a syringe seat disposed at a bottom of the inner cavity, (b) a valve disposed below the inner cavity, and (c) a blade coupled to the handle, wherein the blade includes a housing connected to a camera having a lens.
1 . A laryngoscope comprising:
a syringe having a first longitudinal axis;
a handle having a proximal end, a distal end, and a second longitudinal axis coaxially aligned with the first longitudinal axis, the handle comprising (a) an inner cavity configured to accept at least fifty percent of a length of the syringe, the inner cavity having a first open end and a closed second end, (b) a syringe seat disposed and affixed at a bottom of the inner cavity closer to the closed second end than the first open end, (c) a valve disposed below the inner cavity adjacent the syringe seat, (d) an electronic communication slot defined in the handle adjacent the proximal end;
a cable hub having a connector for electronically and removably coupling to the electronic communication slot, the cable hub having an image processor;
a blade coupled to the distal end of the handle and unitarily formed therewith, the blade comprising a housing including a camera and a lens;
a data cable extending from the communication slot to the camera;
a tubing coupled to and in communication with the valve, the tubing extending through a portion of the blade; and
a nozzle connected to the tubing, wherein the nozzle is juxtaposed the lens, and the nozzle includes an aperture configured to spray fluid onto the lens;
wherein the handle further includes an axial slot disposed parallel with the inner cavity, and further comprising a hub at least partially receivable within the axial slot.
2 . The laryngoscope of claim 1 , wherein the inner cavity has a cavity length that is greater than fifty percent of the length of the syringe.
3 . The laryngoscope of claim 1 , wherein the inner cavity has a cavity length that is greater than seventy-five percent of the length of the syringe.
4 . The laryngoscope of claim 1 , wherein the tubing extends to a position juxtaposed the lens.
5 . The laryngoscope of claim 1 , wherein the nozzle includes a fluid-tight terminal end.
6 . The laryngoscope of claim 1 , wherein the camera and the nozzle are on a bottom of the blade.
7 . The laryngoscope of claim 1 that further comprises a secondary spraying system.
8 . The laryngoscope of claim 7 , wherein the secondary spraying system includes a secondary port disposed on the handle.
9 . The laryngoscope of claim 8 , further comprising a secondary line extending through the blade and terminating at a secondary nozzle, wherein the secondary nozzle is configured to spray fluid onto the lens or into the oropharynx.
10 . The laryngoscope of claim 9 , wherein the secondary nozzle is disposed distal to the primary nozzle.
11 . The laryngoscope of claim 9 , wherein the secondary nozzle is configured to spray a fluid through a distalmost end of the blade.
12 . The laryngoscope of claim 9 , further comprising a secondary valve coupled to the secondary line.
13 . The laryngoscope of claim 1 , further comprising an imaging processor disposed within the hub.
14 . The laryngoscope of claim 1 , further comprising a light source juxtaposed to lens, wherein the light source is configured to heat the lens and/or provide illumination for the camera.
15 . The laryngoscope of claim 14 , wherein the light source is one or more LEDs.
16 . The laryngoscope of claim 14 , wherein the light source is positioned in the housing.
17 . The laryngoscope of claim 1 , wherein the cable hub is disposed outside the inner cavity.
18 . A laryngoscope comprising:
a syringe having a first longitudinal axis;
a handle having a proximal end, a distal end, and a second longitudinal axis coaxially aligned with the first longitudinal axis, the handle comprising (a) an inner cavity configured to accept at least fifty percent of a length of the syringe, the inner cavity having a first open end and a closed second end, (b) a syringe seat disposed and affixed at a bottom of the inner cavity closer to the closed second end than the first open end, (c) a valve disposed below the inner cavity adjacent the syringe seat, (d) an electronic communication slot defined in the handle adjacent the proximal end;
a cable hub having a connector for electronically and removably coupling to the electronic communication slot, the cable hub having an image processor;
a blade coupled to the distal end of the handle and unitarily formed therewith, the blade comprising a housing including a camera and a lens;
a data cable extending from the communication slot to the camera;
a tubing coupled to and in communication with the valve, the tubing extending through a portion of the blade; and
a nozzle connected to the tubing, wherein the nozzle is juxtaposed the lens, and the nozzle includes an aperture configured to spray fluid onto the lens, wherein the electronic communication slot is an axially-extending slot that is parallel with the first longitudinal axis.
