FIELD OF THE INVENTION
The invention relates to an improved laryngoscope with an integrated video camera for wired or wireless video capture.
BACKGROUND OF THE INVENTION
Laryngoscopy is a medical procedure that allows medical professionals to view and observe the glottis or vocal cords in the larynx of a human. In effect, this procedure is endoscopy of the larynx. Laryngoscopy is also performed to allow for tracheal intubation during general anesthesia; cardiopulmonary resuscitation; surgical procedures; etc.
There are several different types of laryngoscopies including direct, direct fiber-optic, direct video, and indirect. Direct laryngoscopy is an involved procedure wherein the patient lies on their back; while a laryngoscope is inserted into the patient’s mouth to hold down the patient’s tongue; while simultaneously lifting up the patient’s epiglottis. The epiglottis is a flap of cartilage that covers the patient’s larynx, also known as the windpipe. The epiglottis opens during breathing and closes during swallowing. The direct laryngoscopy procedure allows the medical professional to view the patient’s glottis via a direct line of sight. This procedure is most often employed by anesthesiologists and other medical professionals like an otolaryngologist or an anesthetists for endotracheal intubation under general anesthesia. These professionals may also use the laryngoscope in direct diagnostic laryngoscopy with biopsy.
Similar to the direct laryngoscopy procedure described above, fiber-optic laryngoscopy involves placing a small telescope at the end of a flexible fiber-optic cable. The telescope and flexible fiber-optic cable can be inserted through the mouth or nose; and then extended further down the throat to view the glottis. The glottis is then viewable via the telescope and flexible fiber-optic cable as images are transmitted to an attached lens, eye piece, or monitor for visualization. Similarly, direct video laryngoscopy includes an image sensor or a video camera integrated into a flexible cable or blade of the laryngoscope. The video camera captures an image of the glottis and the image is transmitted to an attached monitor allowing view of the larynx.
Indirect laryngoscopy involves the medical professional using a small mirror and light to peer into the patient’s throat. The mirror is on a long handle and is placed against the roof of the patient’s mouth, like a dental mirror. A light is then shined into the patient’s mouth to allow the medical professional to view the reflection of the glottis or larynx in the mirror.
Prior art direct video laryngoscopy (VL) systems have not been very successful in the medical industry. VL systems have been associated with higher rates of complications. VL systems also did not yield higher first-attempt tracheal intubation success rates than direct laryngoscopy system. (see Annals of Intensive Care, “Video laryngoscopy for first-attempt tracheal intubation in the general ward,” by Moon Seong Baek, et. Al.; published Aug. 13, 2018). These systems have failed primarily due to their cost, bulky designs, difficult user interfaces, and their complicated set up. Also, oral secretions, heat and humidity of the patient’s oral cavity and throat often fog up the camera lens of the video laryngoscope, requiring the entire system to be removed and cleaned during use, potentially causing issues with the overall procedure. What is needed in the industry is a VL system that is inexpensive, simple to use, mobile, with an intuitive user interface, non-bulky design, and with systems to prevent or mediate camera fogging.
SUMMARY OF THE INVENTION
The present invention contemplates a novel video laryngoscopy system that is inexpensive, easy to use, with an intuitive user interface, non-bulky design, easily mobile, and with a fogging and humidity mitigation system for the camera lens.
A first embodiment of the present invention provides a laryngoscope comprising a handle having a distal end, a proximal end, and a middle portion. The distal end of the handle has a connector portion for receiving a larynx blade. Along its distal end, the larynx blade has an integrated camera or image sensor, camera lens, and a fogging and humidity mitigation system for the camera lens. The camera or image sensor can capture images in the optical spectrum, infrared, ultra-violet, or other optical spectrums. The larynx blade further has an elongated portion, followed by a connector portion at its proximal end. The connector portion of the larynx blade allows the integrated camera and camera lens fogging and humidity mitigation system to connect electromechanically, mechanically, electrically, and/or wirelessly to the distal end of the handle via the handle’s connector portion. The proximal end of the handle also has a peripheral port for connecting to peripheral devices. The peripheral port allows the handle to connect electromechanically, mechanically, electrically, and/or wirelessly to a peripheral such as a display screen. The peripheral port can be fixed or adjustable to allow a peripheral device such as a display to be placed in an optimal viewing position. The proximal end of the handle can also contain controls for operating the laryngoscope. Ergonomic grips can be integrated into the middle portion of the handle for holding and controlling the laryngoscope.
In a second embodiment, the distal end of the handle contains a blade connector for electromechanically, mechanically, electrically, and/or wirelessly connecting and engaging a variety of different blade types for the laryngoscope. These different blade types can include Macintosh, Miller, and other types of curved and straight blades. Furthermore, the blades can contain an integrated camera and light source at the distal end of the blade. The camera lens can include a fogging and humidity mitigation system such as an integrated camera lens wiper for removing secretions, condensation, and debris from the camera lens. This fogging and humidity mitigation system can be integrated into the distal end of the blade with the camera lens. Controls for operating the camera and fogging and humidity mitigation systems for removing condensation and secretions from the camera lens can be integrated into the handle at its distal end or integrated into a user interface within a peripheral device. The user interface within the peripheral device can connect with the fogging and humidity mitigation system via the peripheral port in the handle using electromechanical, mechanical, electrical, and/or wireless means.
In still a further embodiment, the proximal end of the handle contains the peripheral port for electromechanically, mechanically, electrically, and/or wirelessly connecting to peripheral devices; and wherein said peripheral devices can include a detachable smart mobile device and display. The peripheral port is powered by electrical and electronic components that are integrated within the handle for capturing, storing, and transmitting video and images captured by the blade’s integrated camera. The connector portion of the larynx blade allows the integrated camera and camera lens fogging and humidity mitigation system to connect electromechanically, mechanically, electrically, and/or wirelessly to the distal end of the handle via the handle’s connector portion and these components further connect to the peripheral port components at the proximal end of the handle. Electromechanical, mechanical, electrical, and/or electronic components for wirelessly transmitting video and images captured by the integrated camera can also be integrated into the handle or into the peripheral device. The handle can contain a battery for powering the electrical and electronic components, the integrated camera, light source, and camera lens wiper.
In a further embodiment, the blade contains a folding mechanism that engages the connector portion of the handle and wherein the folding mechanism allows the blade to be folded 180 degrees relative to the handle portion.

The blade 210, 310 of the laryngoscope 400 is attached to the handle 220, 320 wherein a provider can manipulate the handle 220, 320 and the blade 210, 310 to perform a laryngoscopy 100. Video from the integrated camera sensor 370 within the blade 210, 310 is transferred 450 via electronics in blade 210, 310 and/or the handle 220, 320 to the peripheral device 410. This video transfer 450 between the integrated camera sensor 370 and the peripheral device 410 can occur via wired or wireless means. At step 460, the application executing the peripheral device 410 can be used to add metadata, medical notes, and other information to the video being captured by the laryngoscope 400. Once the procedure is completed, the peripheral device 410 is disconnected and the entire laryngoscope 400 and blade 310 can be discarded at step 470.
FIG. 5A provides an alternative embodiment of the laryngoscope 500. Here, a dedicated external peripheral display device 510 is provided.

Further at the proximal end of the base 535 is a peripheral connector 565. The peripheral connector 565 rest within the base 535. This peripheral connector 565 can be Universal Serial Bus (USB) connector, IEEE 1394 (FireWire), or any other wired data transfer and/or power connector. Within the handle 545 additional mechanical components and electronics can be placed to allow the peripheral connector 565 to attached to the peripheral display device 510 electromechanically, mechanically, electrically, and/or wirelessly.
Turning now to FIG. 5B, a system for pairing the laryngoscope 300, 400, 500 to the peripheral display device 510 or another external device is outlined. The laryngoscope 500 is simply removed from its pouch 520 and the peripheral display device 510 is attached 530 to the disposable laryngoscope 300, 400, 500. The combined unit is then powered on 540 by pressing the power button 350 and/or interacting with the user interface 445. Once the laryngoscope 500 is powered on, the laryngoscopy 100 is performed 550. Video from the camera sensor 370 within the blade 310 is transferred 550 via wired or wireless electronics within the blade 310 and handle 320 to the peripheral display device 510. The peripheral display device 510 can have integrated storage for retaining the video. At step 560, the peripheral display device 510 is removed and docked at a workstation wherein an application executing on a workstation can add metadata and other information to the video that was captured by the camera sensor 370. Once the procedure is completed, the entire laryngoscope 300, 400, 500 and blade 310 is discarded at step 570; whilst the peripheral display device 510 is retained for later use.

Once the procedure is completed, the entire laryngoscope 600 and blade 610 is discarded but the peripheral display device 670 is retained for later use.
FIG. 6D illustrates a further embodiment of a laryngoscope 600 and blade 610 that is used without an attached display. Instead, in an embodiment, the laryngoscope 600 is used to perform a laryngoscopy procedure while the blade wirelessly 680 transmits data and video to a workstation 690. The wireless 680 data and video transfer can occur in a real time and/or it can be uploaded to the workstation 690 later. In a further embodiment, the data and video transfer can occur via a wired or wireless connection between the peripheral port 660 and the workstation 690. The capture and transfer of video can be controlled by control input 650 or via a user interface 445. The workstation 690 may also include video monitors, computer workstations, and other video and data capture devices.
Although the subject matter has been described in language specific to structural features and/or methodological acts, it is to be understood that the subject matter defined in the appended claims is not necessarily limited to the specific features or acts described above. Rather, the specific features and acts described above are disclosed as example forms of implementing the claims.
