Abstract
A laryngoscope system includes a light source configured to emit light, a camera configured to obtain image data, and a blade having a channel sized to fit over the light source and the camera. The channel includes a closed end surface, a lateral surface, and a texture or a coating applied to the lateral surface.
Claims19
A laryngoscope system, comprising:
- a body comprising a handle and an arm;
- a light source, positioned at a distal end of the arm, configured to emit light;
- a camera, positioned at the distal end of the arm, configured to obtain image data;
- and
- a laryngoscope blade comprising a channel sized to fit over the light source and the camera, wherein the channel comprises:
- a closed end surface at a distal end of the channel;
- an upper surface extending from the closed end surface;
- a lower surface extending from the closed end surface;
- a lateral surface extending from the closed end surface and connected to the upper surface and the lower surface;
- and
- a glare-reducing texture or a glare-reducing coating applied to a portion of the lateral surface extending from the position of the camera to a distal end of the closed end surface.

A laryngoscope system, comprising:
- a body comprising a handle and an arm;
- a light source positioned at a distal end portion of the arm;
- a camera positioned at the distal end portion of the arm;
- and
- a laryngoscope blade comprising:
- a channel sized to fit over the arm;
- a closed end surface that is configured to enable light from the light source to pass through the closed end surface of the channel and to enable the camera to obtain image data through the closed end surface of the channel while the channel is fitted over the arm;
- a first lateral surface and a second lateral surface positioned on opposite lateral sides of the closed end surface, wherein the first lateral surface and the second lateral surface extend from a distal end portion of the arm towards a distal end of the laryngoscope blade;
- a glare-reducing texture applied to the closed end surface, the first lateral surface, the second lateral surface, or any combination thereof;
- and
- an untextured area, wherein the glare-reducing texture has a first roughness average, and the untextured area has a second roughness average that is less than the first roughness average.
8 more elements
A blade for a laryngoscope, the blade comprising:
- a blade body that defines a channel sized to receive a camera stick of the laryngoscope;
- a closed end surface, at a distal end of the channel, that is configured to enable light from a light source to pass through the closed end surface of the channel;
- a first lateral surface and a second lateral surface positioned on opposite lateral sides of the closed end surface, wherein the first lateral surface and second lateral surface extend towards a distal end of the laryngoscope blade;
- and
- a glare-reducing texture or a glare-reducing coating applied to the first lateral surface and the second lateral surface.
