Abstract

A laryngoscope, including a blade having a flat top surface and a bottom surface extending from a base of the blade and a first vertical projection and a second vertical projection at the base of the blade extending from the bottom surface of the blade and a connector configured to couple to a handle of the laryngoscope and further configured to couple to the base of the blade via a first opening configured to receive the first vertical projection and a second opening configured to receive the second vertical projection, wherein the base of the blade and a first portion of the blade are transparent or translucent and a second portion of the blade is opaque, and the base of the blade further includes a cutout aligned with a channel in the connector between the first opening and the second opening when the blade is coupled to the connector.

Claims (30)

1 . A laryngoscope, comprising:

a blade having a flat top surface and a bottom surface extending from a base of the blade, the flat top surface and the bottom surface joined by a first sidewall and a second sidewall forming a hollow channel, and a first vertical projection and a second vertical projection at the base of the blade extending from the bottom surface of the blade; and

a connector configured to couple to a handle of the laryngoscope and further configured to couple to the base of the blade via a first opening, the first opening being configured to receive the first vertical projection and a second opening configured to receive the second vertical projection,

wherein the base of the blade and a first portion of the blade are transparent or translucent and a second portion of the blade is opaque, and

the base of the blade further includes a cutout aligned with a channel in the connector between the first opening and the second opening when the blade is coupled to the connector.

2 . The laryngoscope of claim 1 , wherein the base of the blade and the first portion of the blade are acrylic.

3 . The laryngoscope of claim 1 , wherein the second portion of the blade is coated in aluminum.

4 . The laryngoscope of claim 1 , wherein the second portion of the blade is approximately two-thirds of a length of the blade.

5 . The laryngoscope of claim 1 , wherein the second portion of the blade includes a tip of the blade.

6 . The laryngoscope of claim 1 , wherein the bottom surface of the blade is reinforced with aluminum.

7 . The laryngoscope of claim 1 , wherein the channel of the connector is optically coupled to an illumination source.

8 . The laryngoscope of claim 7 , wherein the illumination source is a fiber optic cable.

9 . The laryngoscope of claim 1 , wherein the blade is curved.

10 . The laryngoscope of claim 1 , wherein the hollow channel is fully hollow.

11 . A laryngoscope, comprising:

a curved blade having a flat top surface and a bottom surface extending from a base of the curved blade, the flat top surface and the bottom surface joined by a first sidewall and a second sidewall forming a hollow channel, and a first vertical projection and a second vertical projection at the base of the curved blade extending from the bottom surface of the curved blade; and

a connector configured to couple to a handle of the laryngoscope and further configured to couple to the base of the curved blade via a first opening, the first opening being configured to receive the first vertical projection and a second opening configured to receive the second vertical projection,

wherein the base of the curved blade and a first portion of the curved blade are transparent or translucent and a second portion of the curved blade is opaque.

12 . The laryngoscope of claim 11 , wherein the base of the curved blade and the first portion of the curved blade are acrylic.

13 . The laryngoscope of claim 11 , wherein the second portion of the curved blade is coated in aluminum or the bottom surface of the curved blade is reinforced with aluminum.

14 . The laryngoscope of claim 11 , wherein the second portion of the curved blade is approximately two-thirds of a length of the curved blade.

15 . The laryngoscope of claim 11 , wherein the second portion of the curved blade includes a tip of the curved blade.

16 . A laryngoscope, comprising:

wherein the base of the blade and a first portion of the blade are transparent or translucent and a second portion of the blade is opaque.

17 . The laryngoscope of claim 16 , wherein the base of the blade and the first portion of the blade are acrylic.

18 . The laryngoscope of claim 16 , wherein the second portion of the blade is coated in aluminum.

19 . The laryngoscope of claim 16 , wherein the second portion of the blade is approximately two-thirds of a length of the blade.

20 . The laryngoscope of claim 16 , wherein the second portion of the blade includes a tip of the blade.
