Technical Field

[0001] The present invention relates to the field of medical equipment, in particular to a video laryngoscope. More specifically, the present invention relates to a video laryngoscope that incorporates software-controlled features for real-time image capture, image orientation correction, secure data storage, and data transmission. Background Art

[0002] Endotracheal intubation is an important medical procedure that is often performed during surgery or in emergency situations to secure the patient's airway. Traditionally, laryngoscopes are used to help clinicians view the airway during intubation. However, conventional laryngoscopes often face challenges such as limited visibility, risk of image distortion due to improper lighting, and a lack of integrated features for data management. These limitations are particularly evident in patients with a high body mass index (BMI) or other anatomical challenges, where visibility and maneuverability of the device are limited.

[0003] Additionally, modern medical practice requires secure handling of patient data, including images and videos captured during procedures. Existing devices often lack integrated software capabilities that ensure real-time data capture, secure storage, and seamless access for viewing. Lack of proper encryption and password protection further increases the risk of unauthorized access to sensitive medical data.

[0004] Therefore, there is a need for a videolaryngoscope that not only enhances visual capabilities during intubation but also integrates advanced software features for data management, security, and ease of use. Summary of the invention

[0005] The present invention relates to a method for operating a video laryngoscope, which can enhance the endotracheal intubation process by integrating advanced image management, data security and user interaction functions. The method can involve controlling a display unit attached to a laryngoscope handle to present visual data captured by a camera housing located at the distal end of the handle. The display unit can automatically adjust the orientation of the displayed visual data based on the angle of the display unit relative to the handle. The video laryngoscope can capture visual data and store the captured visual data in a memory module within the display unit, and provide a user interface that allows the user to configure settings, view stored data, and initiate data capture. It can use password-protected encryption to achieve a secure connection to an external device to transmit visual data.

[0006] In one aspect, the video laryngoscope can automatically adjust the image orientation if the display unit is rotated beyond a predefined angle. The user interface can provide an interactive menu that can be accessed through touch gestures, allowing the clinician to adjust brightness, contrast, and audio settings. The visual data can be encrypted with a user-configurable password to make access and transmission secure, thereby ensuring patient confidentiality.

[0007] The video laryngoscope may include a processor and a memory module for storing visual data related to the medical procedure. The display unit may include a touch screen interface for user interaction, and a software module that may control the capture, display, storage and transmission of the visual data. The software may automatically initiate recording when the laryngoscope is activated, marking key moments during the procedure. The video laryngoscope may include a multi-factor authentication protocol for accessing stored data and modifying settings, thereby ensuring compliance with healthcare data security standards.

[0008] The video laryngoscope can be configured to communicate wirelessly with external medical equipment and displays, allowing real-time or recorded visual data to be securely shared. The software module can also provide real-time analysis tools to help clinicians identify anatomical structures and obstructions during intubation.

[0009] The non-transitory computer readable medium may store program instructions executable by a processor of the video laryngoscope. The instructions may cause the processor to automatically adjust display settings based on sensor data from the laryngoscope, use encryption to protect stored data, and provide a customizable user interface for interaction. The software may allow automatic adjustment of brightness based on ambient lighting, notify the user when image orientation is corrected, and enable automatic recording and marking of important moments during the procedure.

[0010] Video laryngoscopes can support cloud-based data management for secure backup and retrieval, enabling remote access by authorized personnel. Programs can allow secure wireless data transmission to external medical devices using encrypted protocols, ensuring compliance with medical data security standards. In addition, video laryngoscopes can provide real-time recommendations and alerts based on visual data captured during intubation, thereby improving clinical accuracy and patient safety.

[0011] It is an object of the present invention to provide a video laryngoscope with integrated software which enhances the usability of the device by automatically adjusting the orientation of the displayed image based on the position of the display unit during an intubation procedure.

[0012] Another objective is to implement a secure data management system within the video laryngoscope using password-protected encryption to protect the stored visual data, thereby ensuring compliance with medical data privacy regulations.

[0013] Furthermore, a user-friendly interface is provided on the display unit of the video laryngoscope, allowing the clinician to easily access settings, view stored data, adjust display parameters, and initiate recordings through intuitive touch gestures and controls.

[0014] Yet another object is to automatically capture and store visual data related to an endotracheal intubation procedure using software that can mark important moments during the procedure for review and analysis.

[0015] Yet another objective is to facilitate secure wireless or wired data transfer of recorded images and videos to external devices such as PCs, tablets, or cloud-based storage systems, while maintaining the highest levels of security through encryption and multi-factor authentication.

[0016] In addition, a real-time image enhancement system integrated into the software is provided that dynamically adjusts brightness, contrast, and other visual characteristics based on feedback from the camera and light sensors.

[0017] Additionally, cloud-based data management features are integrated to enable remote access, backup, and retrieval of patient data, ensuring the video laryngoscope complies with healthcare data security standards while providing access to clinical data from anywhere.

[0018] Yet another object is to improve procedural efficiency by providing software that initiates automatic recording when the laryngoscope is activated and allows the clinician to interact with the video laryngoscope using touch-based controls, thereby enhancing the overall workflow during critical medical procedures.

[0033] The terms "first", "second", etc. herein do not denote any order, quantity, or importance, but are used to distinguish one element from another, and the terms "one" and "an" herein do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced items. The disclosed embodiments are merely examples of the invention that may be embodied in various forms.

[0034] Now refer to Figure 1 , Figure 2a and Figure 2b, shows a video laryngoscope 100 according to the present invention. The video laryngoscope 100 includes a handle 10, a blade 20, a display unit 30, and an attachment assembly 25 for attaching the display unit 30 to the handle 10. The handle 10 is an elongated member having an ergonomic design that allows a clinician to easily hold the handle 10 during the intubation process. The handle 10 has an upper end and a lower end. The upper end of the handle 10 is provided with a receiving port 12 for receiving the attachment assembly 25.

[0035] The lower end of the handle 10 is provided with a tapered portion 14. Specifically, the lower end of the handle 10 is provided with a camera channel 15 extending from the tapered portion 14 of the handle 10. The camera channel 15 is a flexible link extending from the tapered portion 14 of the handle 10, and the camera channel 15 includes a circuit to transmit visual data (such as images and videos) to the receiving port 12. Specifically, the camera channel 15 is electrically connected to the first terminal 122 of the receiving port 12. The camera channel 15 has: a first end connected to the tapered portion 14 of the handle 10; and a second end including a camera kit 16. The camera kit 16 of the camera channel 15 is configured to capture visual data of the path of the endotracheal tube, larynx, trachea, or airway.

[0036] Now refer to Figure 1 and Figure 3 , the camera kit 16 includes an image sensor 161 and a light source 162. The image sensor 161 helps capture visual data of the path of the endotracheal tube, larynx, trachea or airway. Specifically, the image sensor opening 1611 in the camera kit 16 allows the image sensor 161 to capture visual data of the path of the endotracheal tube, larynx, trachea or airway. In the current aspect of the present invention, the image sensor 161 is a 2 megapixel (MP) camera, but those skilled in the art can use any other image sensor 161 with different specifications. For example, those skilled in the art can configure the image sensor to meet different specifications, such as a higher resolution sensor (e.g., 5MP or 10MP) for more detailed imaging. The image sensor can also include options for adjusting image brightness, contrast, and zoom functions to obtain better visual data of the intubation path.

[0037] In addition, the camera kit 16 includes a light source opening 1621 to allow the light source 162 to illuminate the path of the endotracheal tube and the airway. In addition, the camera kit 16 has a deflector 18. Specifically, the deflector 18 is arranged on the outer surface of the camera kit 16 and separates the image sensor opening 1611) from the light source opening 1621. The deflector 18 prevents the light source 162 from being directly exposed to the image sensor 161. The light source 162 is configured to provide focused illumination of the path of the endotracheal tube, larynx and trachea. Depending on the clinical environment or the patient's anatomical structure, the light source can be configured to emit light of different intensities. In particular, the light source is adjustable to illuminate dark or blurred areas, thereby ensuring clear visibility during the intubation process.

[0038] In the present aspect of the invention, the deflector 18 is a rectangular strip-shaped member such as Figure 4 As shown. The rectangular strip is made of a silicone material. Those skilled in the art may configure the deflector 18 to have any other material, shape or size depending on the size and position of the image sensor 161 and the light source 162. The deflector 18 is arranged horizontally between the light source opening 1621 and the image sensor opening 1611 to avoid light scattering on the image sensor 161. Specifically, the deflector 18 is positioned between the light source 162 and the image sensor 161 to minimize light scattering that may blur or distort the visual data captured by the image sensor 161. The deflector is made of a silicone material that is known for its light absorbing properties, but other light absorbing materials (such as polycarbonate or specialty plastics) may also be used. This ensures that the captured image is clear and there is no glare or halo that may obscure the clinician's field of view.

[0039] Now refer to Figure 3 and Figure 4 , the deflector 18 includes a rectangular portion 181 and two supporting portions 182a, 182b extending from the ends of the rectangular portion 181. The two supporting portions 182a, 182b are provided with corresponding locking elements 1821a, 1821b to attach the deflector 18 to the camera device kit 16. Specifically, the camera device kit 16 has two openings, not shown, to receive the locking elements 1821a, 1821b of the two supporting portions 182a, 182b to hold the deflector 18 on the outer surface of the camera device kit 16. The deflector 18 is attached to the camera device kit 16 in a fixed manner using the locking elements 1821a, 1821b, but those skilled in the art may provide the deflector 18 to be detachable from the camera device kit 16. Specifically, if the deflector 18 has been damaged or needs to be replaced, the deflector 18 may be detached from the camera device kit 16.

[0040] In another aspect of the present invention, the deflector 18 is a protrusion (not shown) extending from the outer surface of the camera assembly 16. The protrusion is disposed between the image sensor opening 1611 and the light source opening 1621 to avoid direct light exposure from the light source 162 to the image sensor 161. The scattering of light from the light source 162 distorts and blurs the image. The deflector 18 avoids direct exposure of the light source 162 to the image sensor 161 to avoid distortion and blurring of the image.

[0041] In another aspect of the present invention, the deflector 18 is a thin sheet disposed between the image sensor opening 1611 and the light source opening 1621. The sheet may be made of any material that absorbs light to avoid direct exposure of the light source 162 on the image sensor 161.

[0042] Now refer to Figure 1 and Figure 5 , a display unit 30 is provided, which can be attached to the handle 10 by an attachment assembly 25. The attachment assembly 25 includes a housing 27 and a second terminal 28 electrically connected to the display unit 30. The housing 27 is connected to the display unit 30 using a hinge 26. The hinge 26 is configured to pivot the display unit 30 in the front-to-back direction. The hinge 26 is connected to the display unit 30 and the housing 27. Specifically, the hinge 26 has a connecting element (not shown) suitable for attachment to the housing 27. The housing 27 receives the connecting element of the hinge 26 to allow the display unit 30 to rotate freely around the central axis of the handle 10. The hinge 26 allows the display unit 30 to rotate in all possible directions to configure the display unit 30 in a desired position, thereby providing better visibility for the clinician. The hinge 26 that connects the display unit 30 to the handle 10 allows 360-degree rotation, but it also includes predetermined stops at angles such as 45 degrees, 90 degrees, 180 degrees, and 270 degrees. These stops are built into the hinge mechanism, ensuring that the display unit locks into place at these angles. This helps the clinician maintain a stable and optimal view of the airway during intubation without the need for manual adjustments. Automatic image adjustment ensures that the image remains correctly oriented regardless of the rotation of the display unit.

[0043] In addition, the housing 27 includes two spherical protrusions 271a, 271b extending from the outer surface of the housing 27 and arranged opposite to each other to securely attach and detach the housing 27 to and from the handle 10. The two spherical protrusions 271a, 271b are offset to extend radially away from the central axis of the housing 27. The housing 271a, 271b is attached to the receiving port 12 of the handle 10. Specifically, the receiving port 12 has two openings to receive the corresponding spherical protrusions 271a, 271b of the housing 27 to securely hold the housing 27 in the receiving port 12 of the handle 10. The two spherical protrusions 271a, 271b ensure that the housing 27 remains in place until the two spherical protrusions 271a, 271b are pressed to detach the housing 27 of the attachment assembly 25. Specifically, the two spherical protrusions 271a, 271b have corresponding balls arranged at the extreme ends to easily press the two spherical protrusions 271a, 271b when removing the housing 27 from the handle 10. The two spherical protrusions 271a, 271b are located on opposite sides of the housing 27. These spherical protrusions are mechanically biased to extend radially outward from the housing 27 and engage with corresponding sockets in the receiving port 12 of the handle 10. This engagement ensures a secure attachment, while pressing the spherical protrusions inward allows for quick removal of the display unit 30. The spherical protrusions are designed to operate with minimal force, allowing the clinician to quickly adjust or remove the display unit during the intubation procedure.

[0044] Once the display unit 30 is attached to the handle 10 via the attachment assembly 25, the second terminal 28 of the attachment assembly 25 is electrically connected to the first terminal 122 of the receiving port 12 of the handle 10 to establish an electrical connection between the camera channel 15 and the display unit 30. Specifically, after the attachment assembly 25 is attached to the handle 10, the first terminal 122 and the second terminal 28 immediately establish an electrical connection between the image sensor 161 and the display unit 30, thereby enabling instant display of visual information of the path of the endotracheal tube, larynx, trachea or airway on the display screen 34.

[0045] In addition, the attachment assembly 25 includes a record button 271 (eg, Figure 5 271 for capturing images or recording videos. In the current aspect of the present invention, the record button 271 is disposed on a portion of the housing 27. However, those skilled in the art may dispose the record button 271 on any other portion so that the clinician's thumb can easily reach the record button 271 to capture images or record videos. The display unit 30 also includes an automatic image orientation correction feature 30a, such as Figure 7a to Figure 7bAs the display unit 30 is rotated downward or upward approximately 180 degrees or other angles, the image on the display screen 34 is automatically adjusted to ensure proper alignment for the clinician. This is particularly beneficial for procedures involving high BMI patients, where the rotated display screen ensures better visibility and access to the airway.

[0046] Now refer to Figure 1 , Figure 3 and Figure 5 The display unit 30 includes a battery (not shown), a power button 32, an output port 33, a display screen 34, a touch user interface (TUI) (not shown), a processor (not shown), and a memory module (not shown) for storing visual data of the path of the endotracheal tube, larynx, trachea or airway. The video laryngoscope allows the clinician to capture images and videos of the intubation process using a record button arranged on the display unit. The captured data is stored in the integrated memory module. The battery is arranged in the display unit 30 to supply power to the display screen 34, the image sensor 161 and the light source 162. The battery can be a replaceable battery or a rechargeable battery.

[0047] In another aspect of the invention, the handle 10 includes a battery (not shown) that can be used to supply power to the image sensor 161 and the light sensor 162 when the display unit 30 is not attached to the handle 10. In this case, the handle 10 establishes a wireless connection with the display unit 30 or an external display (not shown) to transmit visual data of the path of the endotracheal tube, larynx, trachea, or airway from the image sensor 161 to the display unit 30 or external display.

[0048] The power button 32 is arranged on either side of the side of the display unit 30. The power button 32 is within the range of the clinician's finger. In the current aspect of the present invention, the power button 32 is arranged at the lower left of the display unit 30. The power button 32 is used to power on or off the display screen 34. Specifically, the power button 32 is pressed and released to power on the display screen 34, and the power button 32 is pressed and held for 3 seconds to 4 seconds to power off the display screen 34. Those skilled in the art can configure the duration for holding the power button 32 to power off the display screen 34. In the current aspect, the power button 32 is located at the lower left of the display unit 30. A short press enables the display screen 34, the image sensor 161 and the light source 162, while a long press (3 seconds to 4 seconds) turns off the unit. This minimizes accidental shutdowns and ensures that the display is functioning properly when needed. The record button 271 on the housing also allows the clinician to capture visual data during the procedure, so that the captured data is automatically saved in a safe, password-protected folder.

[0049] In another aspect of the invention, once the display unit 30 is attached to the handle 10 and the display screen 34 is powered on using the power button 32, the display screen 34 begins to display visuals of the path of the endotracheal tube. The display screen 34 automatically begins to display visuals of the endotracheal tube without pressing the record button 271.

[0050] In another aspect of the present invention, the video laryngoscope 100 is adapted to start displaying visual data on the display screen 34 even if the display unit 30 is not attached to the handle 10. The display screen 34 displays the visual data by establishing a wireless connection between the handle 10 and the display unit 30.

[0051] In addition, an output port 33 is provided on either side of the side of the display unit 30 for connecting the display unit 30 to an external display (not shown) to display visual information of the path of the endotracheal tube. The external display has a larger screen size than the display screen 34 of the display unit 30. It is obvious to those skilled in the art that multiple output ports are provided on the display unit 30.

[0052] The display screen 34 of the display unit 30 is adapted to display visual data of the path of the endotracheal tube received from the image sensor 161. In the current aspect of the invention, the display unit 30 has a rectangular shape to accommodate the display screen 34. The display screen 34 has a size of 3.5 inches to provide better visibility from all angles. It is obvious to those skilled in the art that the size of the display screen 34 can be increased as needed.

[0053] In addition, a touch user interface is provided to allow the clinician to interact with the video laryngoscope 100. The touch user interface of the display 34 is suitable for viewing and managing previously recorded images or videos stored in the memory of the display unit 30. The touch user interface includes a home page for displaying the current time and date, a menu icon for accessing multiple icons, and a battery icon for indicating the battery level. The display 34 is powered on using the power button 32 to display the home page. In the present aspect, the touch user interface (TUI) of the display 34 allows the clinician to manually enable functions such as Figure 7a and Figure 7b The image orientation correction feature 30a is shown. The image orientation can be flipped by swiping up on the touch screen 34 or by pressing a dedicated "flip" button on the display unit 30. The clinician interacts with the menu icon of the home page by touching the menu icon displayed on the display screen 34 to access multiple icons. The menu icon is set in the lower left corner of the display screen 34 to allow the clinician to reach the menu icon with one hand. After touching the menu icon, the processor receives the touch input from the touch user interface and processes the command to display multiple icons on the display screen 34.

[0054] In addition, the video laryngoscope 100 includes a security mechanism 30b for storing visual data (eg, images and videos captured during the intubation process), such as Figure 8a and Figure 8b as shown. Access to data stored on the display unit 30 requires a password, which can be defined by the user. The default password is "000000", but the clinician can configure it to any six-digit combination to enhance patient data security. The touch screen interface on the display unit 30 provides intuitive navigation of the device's settings and stored data. Clinicians can interact with the touch user interface (TUI) using simple gestures (such as swiping or tapping icons) to adjust brightness, access stored images, or enable image orientation correction features. The touch screen is also designed to remain responsive even when the clinician is wearing medical gloves, ensuring seamless operation. The display unit 30 also includes a security mechanism 30b to protect data during transmission to an external device (e.g., a PC, tablet, or other computing resource), such as an encryption system, such as Figure 8a and Figure 8b As shown in Figure 1. A password is required not only to access the stored data, but also to connect the device to external computing resources, ensuring that sensitive medical data remains secure. Encryption extends to data transmission, ensuring that files sent to external devices such as PCs or tablets are protected by encryption protocols such as AES-256. This level of encryption ensures compliance with healthcare data security standards.

[0055] A plurality of icons are assigned with specific actions to be performed upon receiving a command from the processor of the display unit 30. Specifically, the plurality of icons include a setting icon for changing the brightness of the display screen, the volume of the sound, opening or closing the output port 33, etc. In addition, the plurality of icons include a photo icon for viewing and managing previously recorded images and a video icon for viewing and managing previously recorded videos. In another aspect of the present invention, the plurality of icons include a folder icon for viewing and managing previously recorded images and videos in one place. Those skilled in the art may add more icons to the plurality of icons to provide additional features and functions.

[0056] When the clinician presses the record button 29 to capture an image, the touch user interface is adapted to display an indication of the captured image on the display screen 34. Additionally, when the record button 29 is pressed and held to record a video, the touch user interface is adapted to display a timer for the recording on the display screen 34. Additionally, after the record button 29 is pressed to stop recording, the timer disappears from the display screen 34.

[0057] In another aspect of the present invention, the display unit 30 includes a charging lamp 35 for indicating the charging state of the battery. When the battery is connected to a power source to recharge the battery, the charging lamp 35 is lit, and when the battery is not connected to a power source to recharge, the charging lamp 35 is off. It is obvious to those skilled in the art that the charging lamp 35 is arranged in any corner of the display unit 30.

[0058] Now refer to Figure 1 , Figure 5 and Figure 6 , a display cover 40 is provided to prevent the display unit 30 and the attachment assembly 25 from being infected during the intubation process. The display cover 40 is made of a transparent material to allow the clinician to view the display screen 34 without any obstruction. The display cover 40 includes a lower panel 42 and an upper panel 44 hinged at a hinge point. The lower panel 42 and the upper panel 44 pivot about the hinge point to cover the display unit 30. After the display unit 30 is placed in the cavity of the display cover 40, the upper panel 44 and the lower panel 42 of the display cover 40 are pressed to snap fit with each other. In addition, the upper panel 44 has a flexible sheath (not shown) that extends from the free end of the upper panel 44 to cover a portion of the handle 10 and the attachment assembly 25. The display cover 40 is disposable and can be discarded once the intubation process is completed.

[0059] Refer again Figure 1 2 , the handle 10 is adapted to receive a blade 20 from the lower end of the handle 10. The blade 20 is received around the outer surface of the handle 10 to completely cover the handle 10 and the camera channel 15. The blade 20 is attached to the handle 10 when the intubation process is performed. The handle is adapted to receive all types of blades, such as Macintosh and Miller. In addition, the handle 10 is adapted to receive adult blades and pediatric blades. The camera channel 15 is adapted to receive all types of blades for both adults and children, such as Macintosh and Miller. The handle 10 does not require any other adjustment or installation to receive adult blades and pediatric blades. The blade 20 is able to slide on the camera channel 15 to attach to the handle 10 to perform the intubation process. The blade 20 is detachably attached to the handle 10 and can be removed from the handle 10 after the intubation process.

[0060] In the present aspect of the invention, the blade 20 can be attached to the handle 10 by a double ball mechanism 21 of the handle 10. The double ball mechanism 21 includes two spherical protrusions 211a, 211b, which are arranged opposite to each other to firmly attach and detach the blade 20 to and from the handle 10. The two spherical protrusions 211a, 211b are biased to extend radially away from the central axis of the handle 10. The two spherical protrusions 211a, 211b engage with the blade 20. Specifically, the blade 20 has two openings (not shown) to engage with the two spherical protrusions 211a, 211b of the handle 10, thereby firmly holding the blade 20 on the handle 10. The two spherical protrusions 211a, 211b ensure that the blade 20 remains in place until the two spherical protrusions 211a, 211b are pressed to detach the blade 20. The blade 20 is disposed of after being removed from the handle 10 to reduce the chance of infection and cross contamination. Disposal of the blade 20 after a single use allows the video laryngoscope 100 to control the spread of infection that may be spread by repeated use of the same blade.

[0061] In addition, blade 20 has an opening 165 to allow image sensor 161 and light source 162 to capture visual data of the path of the endotracheal tube. Image sensor 161 captures visual data of the path of the endotracheal tube, larynx, trachea or airway and transmits the visual data to display unit 30.

[0062] Before performing the intubation process, the clinician attaches the blade 20 to the handle 10. The blade 20 can be an adult blade or a pediatric blade. The blade 20 can slide on the camera channel 15, and the blade 20 is attached to the handle 10 by a double ball mechanism 21 of the handle 10.

[0063] Now refer to Figures 9a to 9cIn the current embodiment of the present invention, the blade 20 can be attached to the handle 10 by the attachment mechanism 21 of the handle 10. The attachment mechanism 21 includes at least two spherical protrusions 211a, 211b, which are arranged opposite to each other to firmly attach and detach the blade 20 to the handle 10. The two spherical protrusions 211a, 211b are biased to extend radially away from the central axis of the handle 10. The two spherical protrusions 211a, 211b are configured to engage with the blade 20. Specifically, the two spherical protrusions 211a, 211b are biased to extend radially outward from the center of the handle 10 using a biasing member 212 (e.g., a spring member). The biasing member 212 is positioned inside the handle 10 and applies a continuous force to the spherical protrusions 211a, 211b to configure the extended position of the two spherical protrusions 211a, 211b during the attachment of the blade 20. The two spherical protrusions 211a, 211b have corresponding biasing members 212a, 212b to bias the two spherical protrusions 211a, 211b away from the handle 10 to engage the blade 20 and hold the blade 20 in the attached position. When the blade 20 is attached, the spherical protrusions 211a, 211b engage with the corresponding openings 223a, 223b in the blade 20, thereby holding the blade 20 around the handle 10.

[0064] Now refer to Fig.10 , the blade 20 includes an attachment portion 251, a grip portion 252, and a tongue portion 253. The attachment portion 251 is located at the proximal end of the blade 20, and the attachment portion 251 is suitable for attaching the blade 20 to the handle 10. The attachment portion 251 includes at least two openings 223a, 223b positioned to engage with the two spherical protrusions 211a, 211b of the handle 10. The two openings 223a, 223b are configured to engage with the corresponding two spherical protrusions 211a, 211b during the intubation process. The attachment mechanism 21 allows the handle 10 to be removed by pressing the two spherical protrusions 211a, 211b inwardly. The blade 20 has a first cavity 256 formed at the attachment portion 251 and the grip portion 252 of the blade 20. The first cavity 256 has a shape suitable for fitting on the handle 10 and covering the handle 10 during the intubation process. The first cavity 256 allows the blade 20 to receive the handle 10 and hold the handle 10 securely in place during the intubation process. The first cavity 256 is formed at the attachment portion 251 and extends through the grip portion 252.

[0065] The grip portion 252 is a middle section of the blade, and the grip portion 252 is disposed between the grip portion 251 and the tongue portion 253. The grip portion 252 is configured to provide a grip for the clinician during the intubation process. The grip portion 252 has indentations (not shown) or other surface textures on the outer surface of the grip portion 252 to enhance the clinician's grip.

[0066] In addition, the tongue portion 253 is the distal end of the blade 20 located behind the grip portion 252. The tongue portion 253 is configured to interact with the patient's body structure, particularly during intubation. In the present embodiment, the tongue portion 253 is an integral part of the blade 20 and extends laterally from the grip portion 252. The tongue portion 253 is configured to receive the camera channel 15 and the camera kit 16. The tongue portion 253 includes a camera kit opening 165 to accommodate the camera kit 16, which faces the outside of the blade 20, thereby allowing the image sensor 161 disposed within the camera kit 16 to capture visual data of the patient's airway (including the endotracheal tube, larynx and trachea).

[0067] Specifically, the blade 20 has a second cavity 257 formed at the tongue portion 253 of the blade 20. The second cavity 257 is configured to accommodate the camera channel 15 and the camera kit 16 therein. The second cavity 257 accommodates the camera channel 15 extending along the length of the tongue portion 253. The second cavity 257 provides space for the camera channel 15 to be accommodated within the blade 20. In addition, the camera kit 16 is exposed through the camera kit opening 165 arranged in the tongue portion 253 to allow the image sensor 161 to capture visual data of the patient's airway.

[0068] After the cannulation process, the blade 20 can be removed from the handle 10 by pressing the two spherical protrusions 211a, 211b against the biasing force applied by the biasing members 212a, 212b. When pressure is applied to the two spherical protrusions 211a, 211b, the two spherical protrusions 211a, 211b are pushed inward, thereby overcoming the biasing force of the biasing members 212a, 212b and moving toward the center of the handle 10 (e.g., Figure 9b The two spherical protrusions 211a, 211b move toward the center of the handle 10 to disengage the corresponding openings 211a, 211b in the blade 20, thereby allowing the blade 20 to be removed from the handle 10. In particular, after pressing the two spherical protrusions 211a, 211b, the blade 20 can slide on the handle 10 and the camera channel 15 in a downward direction (as shown in FIG. Fig.9c ), thereby completely removing the blade 20 from the handle 10 and discarding the blade 20 after the intubation process.

[0069] In addition, the display unit 30 is placed inside the lower panel 42 of the display cover 40, and the upper panel 44 pivots to close the display cover 40. The flexible sheath is wrapped around the portion of the handle 10 and the attachment assembly 25. Once the flexible sheath is wrapped, the video laryngoscope 100 is ready for the intubation process. The display unit 30 rotates to configure the position according to the clinician's requirements. The hinge 26 facilitates the movement of the display unit 30.

[0070] While performing the intubation process, the power button 32 is pressed to enable the display screen 34, the image sensor 161, and the light source 162. Visual data of the path of the endotracheal tube and the airway is displayed on the display screen 34. The deflector 18 of the camera assembly 16 reduces the scattering of light from the light source 162. The deflector 18 helps reduce the distortion and blur of the image. In addition, a record button 271 is provided for capturing images and recording videos. Press and release the record button 271 to capture images, and press and hold the record button 271 for 2 seconds to 3 seconds to record videos. The video laryngoscope 100 is completely covered from the outside, thereby eliminating the risk of infection of the video laryngoscope 100. After the intubation process, the display cover 40 is removed from the display unit 30 and discarded to avoid spreading infection. In addition, the blade 20 is removed from the handle 10. The blade 20, which mainly contacts the body part, is discarded after one use, which helps reduce the infection rate or cross-contamination transmission rate caused by the reuse of the blade 20.

[0071] In addition, the video laryngoscope 100 allows the clinician to free one hand while operating the video laryngoscope 100 during the intubation process. In the operating room, the clinician needs to free his hands to use multiple devices or perform multiple actions at the same time. By placing the power button 32 at the lower left of the display unit 30, placing the menu icon 34 at the lower left of the display screen, and placing the record button 29 below the display unit 30, the clinician can fully operate the video laryngoscope 100 with his left hand, thereby freeing up his right hand.

[0072] In another aspect of the present invention, a video laryngoscope 100 includes a handle 10, a blade 20, and a display unit 30. The display unit 30 is attached to the handle 10 without using an attachment assembly 25. Specifically, the display unit 30 includes an attachment element (not shown) extending from a bottom portion of the display unit 30 to attach to the handle 10. It is obvious to those skilled in the art that the attachment element of the display unit 30 is configured to provide a threaded attachment or a snap-fit ​​attachment or the like to ensure a secure and functional connection between the display unit 30 and the handle 10.

[0073] In addition, the video laryngoscope 100 includes a software module that provides instructions for controlling the capture, display, storage, and transmission of visual data. When the laryngoscope is activated, the software module automatically initiates recording of the procedure and marks specific moments in the recording based on user input or automatic criteria. The software module provides real-time analysis tools to help identify anatomical structures and potential obstructions during intubation.

[0074] exist Fig.11 In the illustrated aspect, a computer-implemented method 300 for operating a video laryngoscope according to the present invention is provided. The video laryngoscope is integrated with software that improves the overall functionality of the video laryngoscope, particularly in terms of image management, data security, and user interaction. The software is executed by an embedded processor within the display unit 30, which controls various operations of the video laryngoscope.

[0075] Method 300 begins at step 310 .

[0076] At step 320, the display unit 30 is attached to the handle 10 to establish a connection between the image sensor 161 and the display unit 30 through the handle 10. The connection is an electrical connection between the image sensor 161 and the display unit 30 through the camera channel 15 and the handle 10.

[0077] At step 330, a display unit 30 attached to the handle 10 is controlled to present visual data captured by the camera kit 16 located at the distal end of the handle 10. The display unit 30 serves as the primary interface between the clinician and the visual data generated during the intubation procedure. The camera kit 16 located at the distal end of the handle 10 includes an image sensor 161 that is used to capture real-time visual data of the patient's airway. These visual data are useful for guiding the clinician during the insertion of the endotracheal tube into the trachea.

[0078] The display unit 30 attached to the handle 10 is adapted to present these captured visuals to the clinician in real time. The connection between the display unit 30 and the camera assembly 16 enables the clinician to view the path of the intubation tube, thereby ensuring that the endotracheal tube is properly positioned within the airway.

[0079] As the image sensor 161 captures visual data, software processes the data and transmits the data to the display unit 30. The display unit 30 provides clear, high-resolution images with minimal latency, ensuring that the visuals are accurate and immediate, which is useful for maintaining safety during the procedure.

[0080] The attachment mechanism between the display unit 30 and the handle 10 allows for 360 degree rotation, thereby ensuring that the display can be adjusted to the position most convenient for the clinician without interrupting the display of visual data.

[0081] At step 340, the orientation of the displayed visual data is automatically adjusted based on the angle of the display unit 30 relative to the handle 10. The software manages the display of the real-time visual data captured by the image sensor 161. In this embodiment, an orientation sensor is included in the laryngoscope 100 to detect the angle of the display unit 30 relative to the handle 10 and adjust the image accordingly. For example, if the display unit 30 is rotated more than 90° or 180°, the system automatically flips the image to ensure proper alignment. This is useful during procedures involving patients in challenging positions because it maintains clear, upright visuals for the clinician.

[0082] Further at step 350, visual data related to the endotracheal intubation procedure is captured and stored in a memory module within the display unit 30. The system allows the clinician to capture images and videos of the intubation process using the record button 29 disposed on the display unit 30. The captured data is stored in the integrated memory module. The software also allows for automatic marking of key moments during the procedure based on user input or predefined criteria (e.g., detection of anatomical landmarks).

[0083] Further, at step 360, the clinician can browse the stored data using the touch screen interface (TUI) of the display unit 30, allowing them to view, delete or mark important visual materials for later reference. This feature facilitates post-procedure review, documentation, and data management, thereby enhancing the overall utility of the device in a clinical setting. Once the intubation procedure is completed, the video laryngoscope 100 allows the clinician to access and view the stored visual materials. These can include real-time images and recorded videos captured during the procedure. In one aspect, the TUI displays the files in an organized manner, such as sorted chronologically or tagged by specific events, so that the clinician can easily find the exact moment they need to view.

[0084] In one aspect, using the TUI, clinicians can apply labels or markers to any significant moments, making them easier to retrieve later. The marker feature is customizable, allowing clinicians to use predefined markers (such as "difficult airway," "anatomical landmark," or "tube placement") or create their own custom markers related to a specific procedure.

[0085] In one aspect, the TUI is configured to be intuitive and responsive, even when the clinician is wearing medical gloves, thereby ensuring seamless operation during or after a procedure. The interface supports touch gestures such as swiping to navigate visual files, tapping to select and open images or videos, and pinching to zoom in on important details.

[0086] The method ends at step 370 .

[0087] In addition, the system video laryngoscope 100 enables secure connection with external devices using password-protected encryption to transfer visual data. The video laryngoscope 100 has the ability to securely transfer visual data (e.g., images and videos) captured during a medical procedure to an external device including a computer, tablet, or external medical display. This functionality allows secure access to patient data while maintaining data integrity and complying with healthcare data protection standards. The video laryngoscope 100 provides a password-protected encryption mechanism, thereby ensuring that sensitive medical information is protected from unauthorized access during both storage and transmission.

[0088] Upon initiating a connection with an external device, the video laryngoscope 100 requires the user to enter a password to authenticate access. The video laryngoscope 100 includes a default password configuration that can be user defined to enhance security. In one embodiment, the video laryngoscope 100 requires a six-digit password to unlock access to stored data or initiate data transfer to an external device. This prevents unauthorized personnel from accessing sensitive patient information.

[0089] Additionally, the video laryngoscope 100 can be configured to support multi-factor authentication (MFA) for increased security. In this configuration, access to the data and the ability to transfer visual data to an external device is restricted by requiring a password and a secondary authentication factor. For example, MFA can include biometric authentication (e.g., fingerprint scan or facial recognition), or use a time-based one-time password (OTP) sent to a registered mobile device. This additional layer of protection ensures that only authorized users can access or transfer stored visual data.

[0090] Once the user has authenticated, the video data is encrypted prior to transmission. In an exemplary embodiment, the video laryngoscope 100 uses the Advanced Encryption Standard (AES) with 256-bit encryption, which is a widely accepted encryption method in the healthcare industry. AES-256 encryption ensures that even if the data is intercepted during transmission, it cannot be decrypted or accessed by an unauthorized party.

[0091] The encrypted data is then transmitted to an external device via both wired and wireless methods. In one embodiment, the video laryngoscope 100 supports a wired connection (e.g., USB or HDMI) to transmit the data to a computer or larger display system. In another embodiment, the video laryngoscope 100 supports wireless communication protocols including Wi-Fi or Bluetooth, thereby enabling real-time transmission of data to external medical equipment or displays.

[0092] In a wireless configuration, the video laryngoscope 100 can connect to an external medical display or hospital server using password-protected encryption to ensure the security of patient data during transmission. This feature allows clinicians to display real-time visual data on a larger screen or share it with other medical professionals during complex procedures. In another embodiment, the video laryngoscope 100 supports cloud-based storage, allowing remote backup of visual data. Data transmitted to the cloud is encrypted using AES-256 encryption to protect patient privacy and ensure compliance with healthcare data regulations.

[0093] The video laryngoscope 100 also allows authorized personnel to securely retrieve cloud stored data. Access to this data requires password authentication, or, where applicable, multi-factor authentication.

[0094] In a preferred embodiment, during or after the procedure, the clinician initiates secure data transfer by selecting the appropriate function on the touch screen interface. For example, after completing intubation, the clinician may wish to transfer the captured video data to the hospital's electronic medical record (EMR) system. The video laryngoscope 100 prompts the user to enter a password, and upon successful authentication, the video file is encrypted and securely transferred to the EMR system over a secure network connection.

[0095] In an exemplary use case, a clinician uses the video laryngoscope 100 to capture real-time visual data during an intubation procedure. Once the procedure is complete, the clinician initiates data transmission to the hospital's server to store the visual data as part of the patient's medical record. The video laryngoscope 100 prompts the clinician to enter a password to verify access. Once the password is verified, the visual data is encrypted and securely transmitted to the server using AES-256 encryption, ensuring that the data is protected throughout the transmission process.

[0096] If a clinician needs to access that data from a remote location, cloud-based storage options allow authorized personnel to retrieve encrypted data by entering the appropriate password or through multi-factor authentication. This secure connection ensures that only authorized users can access a patient’s sensitive medical information.

[0097] The software also includes customization options that allow clinicians to create shortcuts for commonly used features, streamlining their workflow. For example, shortcuts can be created to quickly access image orientation correction, brightness settings, or reviewing captured data.

[0098] In a preferred embodiment, the video laryngoscope 100 is used during intubation of a high BMI patient. The clinician mounts the Macintosh blade 20 to the handle 10 using a double ball mechanism 21. The clinician rotates the display unit 30 180 degrees to avoid interfering with the patient's chest, and the video laryngoscope 100 automatically adjusts the image orientation to maintain an upright and clear field of view.

[0099] The clinician presses the record button 271 to capture the intubation process. The software marks key moments, such as the placement of the tube, based on predefined criteria. After the procedure, the clinician accesses the captured data through the TUI and reviews the marked moments. The data is securely transmitted to the hospital database using encrypted wireless communication, ensuring that the patient's data is protected.

[0100] In another aspect, a non-transitory computer readable medium storing program instructions executable by a processor of the video laryngoscope 100 according to the present invention is provided.

[0101] Program instructions enable a processor (not shown) to automatically adjust the display settings based on sensor data from the laryngoscope. This feature ensures that the image remains upright and properly aligned regardless of the position of the display. An on-screen indicator provides visual confirmation when the image orientation is adjusted.

[0102] The video laryngoscope 100 may include an ambient light sensor that automatically adjusts the brightness and contrast of the display screen to ensure optimal visibility in a variety of lighting conditions, including dimly lit or brightly illuminated environments.

[0103] To protect visual data, the program contains encryption mechanisms that protect the stored data from unauthorized access. Accessing stored data or connecting to external devices requires multi-factor authentication (MFA), such as a password and biometric input. This ensures compliance with healthcare data security standards.

[0104] The video laryngoscope 100 provides a customizable user interface that allows clinicians to create shortcuts for frequently used features, thereby enhancing the usability of the system during medical procedures. These shortcuts can be configured directly through the touch screen.

[0105] When the laryngoscope is activated, program instructions automatically initiate recording of visual data. Important / critical moments during the procedure are marked based on predefined criteria or user input, ensuring efficient review and analysis at a later time.

[0106] The video laryngoscope 100 supports wireless data transmission to external devices, thereby ensuring secure communication through encryption protocols. The video laryngoscope 100 also provides cloud-based visual data backup, allowing remote access and retrieval by authorized personnel.

[0107] In some embodiments, the software includes real-time analysis tools that assist clinicians by providing suggestions or alerts based on visual data. These suggestions may include identifying anatomical landmarks or warning of potential obstructions during intubation.

[0108] Therefore, the present invention has the advantage of providing a video laryngoscope 100 for performing an intubation process. The video laryngoscope 100 is provided with a display unit 30 that rotates and moves in an anterior-posterior direction to increase the visibility of the clinician. In addition, the handle 10 of the video laryngoscope 100 is adapted to receive adult blades as well as pediatric blades, which reduces other requirements, such as different handles for different blades or mountings for receiving different types of blades on the same handle 10. In addition, the deflector 18 reduces distortion and blurring of the image to obtain better quality visualization. In addition, the blade 20 covers the handle 10, and the display cover 40 covers the display unit 30, which completely covers the video laryngoscope 100 and prevents the video laryngoscope 100 from being infected during the intubation process. The video laryngoscope 100 ensures that the captured visual data is automatically adjusted according to the angle of the display unit relative to the handle. This eliminates the need for manual adjustment, thereby allowing the clinician to maintain clear and upright visual data during intubation, which is particularly beneficial for patients in challenging positions or with high BMI. In addition, clinicians can easily capture and store visual data, such as images and videos, using an intuitive interface. Videolaryngoscope automatically marks key moments during the procedure based on predefined criteria or user input, improving the organization of procedural notes and facilitating post-procedural analysis.
