Video laryngoscope with window for infrared pairing
A video laryngoscope including a display portion, a handle, and a camera assembly. The display portion includes a housing having a patient-facing side and a user-facing side. A display screen is disposed on the user-facing side and configured to display images captured by the camera assembly. An infrared window is disposed at another position on the video laryngoscope, such as on the patient-facing side of the housing. Infrared signals for pairing the video laryngoscope to other devices, such as monitors or external display screens, may be transmitted through the infrared window. For instance, an infrared receiver of the video laryngoscope may receive infrared signals through the infrared window and/or an infrared transmitter of the video laryngoscope may transmit infrared signals through the infrared window.

the housing has a height and a width;
the infrared window has a height and a width; and
the height of the housing is less than 7 times greater than the height of the infrared window.
11 . The video laryngoscope of claim 10 , wherein the width of the housing is less than 6 time greater than the width of the infrared window.
12 . The video laryngoscope of claim 11 , wherein the infrared window is entirely encompassed within a quadrant of the patient-facing side.
13 . The video laryngoscope of claim 8 , further comprising an adhesive tape, wherein:
the housing defines a recessed portion and a ledge; and
the adhesive tape is positioned between the infrared window and the ledge.
14 . The video laryngoscope of claim 8 , wherein the infrared window is translucent to an infrared spectrum and opaque to a human-visible spectrum.
15 . A video laryngoscope system, comprising:
a video laryngoscope comprising:
a housing;
an infrared window in the housing; and
an infrared receiver, disposed within the housing, optically aligned with the infrared window;
an external display screen comprising an infrared emitter configured to be activated to emit an infrared signal comprising identification information of the external display screen; and
wherein the video laryngoscope is configured to receive the infrared signal through the infrared window provided in a housing of the video laryngoscope.
16 . The system of claim 15 , wherein the infrared window is disposed over an opening in the housing.
17 . The system of claim 15 , wherein the video laryngoscope further comprises a display screen coupled to the housing.
18 . The system of claim 17 , wherein the display screen is positioned on a front side of the housing and the infrared window is disposed on a back side of the housing.
