Laryngoscope with integrated and controllable suction

1. A laryngoscope, the laryngoscope comprising:

a handle, said handle comprising an upper internal channel formed within the handle so that the handle and the upper internal channel comprise a single structure;

a suction port configured for connection to an air source at a proximal end of the handle and formed within the handle so that the handle and the suction port comprise a single structure, said suction port defining an opening into the upper internal channel;

a middle internal channel formed within the handle so that the handle and the middle internal channel comprise a single structure, said middle internal channel configured to (a) be operatively connected to at least one port to an external surface of the handle, said operative connection providing fluid communication between the middle internal channel and the at least one port, and (b) be transverse to the upper internal channel; and

a blade formed in connection with the handle such that the handle and the blade comprise one structure, said blade comprising a first set of one or more intake ports and a second set of one or more intake ports;

wherein the laryngoscope comprises a first lower internal channel with a non-circular profile formed within the blade that defines a first air flow path that extends from the upper internal channel to the first set of one or more intake ports,

wherein the laryngoscope comprises a second lower internal channel with a non-circular profile formed within the blade that defines a second air flow path that extends from the upper internal channel to the second set of one or more intake ports,

wherein the middle internal channel is configured to be interposed and provide fluid communication between (a) the upper internal channel and (b) the first and second lower internal channels such that the upper internal channel and the first and second lower internal channels are connected to the at least one port to the external surface of the handle by the middle internal channel,

wherein the first lower internal channel, the second lower internal channel, the middle internal channel, the upper internal channel, the handle and the blade comprise a monolithic structure, and

wherein the second set of one or more intake ports is located at a distance from the first set of one or more intake ports such that the second set of one or more intake ports applies suction in a different part of a patient anatomy from the first set of one or more intake ports.

2. The laryngoscope as recited in claim 1 , the laryngoscope further comprising:

a first valve located at or close to the middle internal channel and interposed between the upper internal channel and the first lower internal channel to regulate air flow along the first air flow path; and

a second valve located at or near the middle internal channel and interposed between the upper internal channel and the second lower internal channel to regulate air flow along the second air flow path.

3. The laryngoscope as recited in claim 2 , wherein the first valve and the second valve inside the laryngoscope are operably connected to each other and at least one switch located at an exterior surface of the laryngoscope that overlay the first valve and the second valve, such that manipulation of the at least one switch is configured to cause the first valve to open or close in an opposing function to the second valve, thereby selectively opening or closing either the first or second lower internal channels.

4. The laryngoscope as recited in claim 2 , wherein the first valve and the second valve are operably connected to at least one switch that is mounted on an exterior surface of the laryngoscope, such that manipulation of the at least one switch causes the first and second valves to open or close independently of each other, thereby allowing independent activation of the first and second lower internal channels.

5. The laryngoscope as recited in claim 1 , wherein the first set of the one or more intake ports is positioned at a distal end of the blade.

6. The laryngoscope as recited in claim 1 , and further comprising a camera housed within the blade for acquiring images during use of the laryngoscope,

wherein the camera comprises at least one lens for acquiring the images,

wherein the at least one lens is oriented perpendicular to an axis of the blade, and

wherein the at least one lens is oriented perpendicular to an axis of the second lower internal channel.

7. The laryngoscope as recited in claim 6 , and further comprising a wireless transceiver for transmitting the images acquired during use of the laryngoscope to a remote display, wherein the wireless transmitter is separated from the first and second lower internal channels by a wall, thereby preventing fluid contact with the wireless transceiver.

8. The laryngoscope as recited in claim 6 ,

wherein the second set of one or more intake ports is positioned in the vicinity of the at least one lens of the camera, and

wherein the second set of one or more intake ports has at least one intake positioned to direct suction flow across the at least one lens, thereby clearing the at least one lens of obstructions in vivo.

9. The laryngoscope as recited in claim 1 , and further comprising a light that is positioned and directed to emit light along the blade of the laryngoscope.
