BACKGROUND

Endotracheal intubation is a critical medical procedure often performed to secure a patient's airway during surgeries or in emergency situations. Traditionally, laryngoscopes have been used to aid clinicians in visualizing the airway during intubation. However, conventional laryngoscopes often face challenges, such as limited visibility, the risk of image distortion due to improper lighting, and a lack of integrated features for data management. These limitations are particularly pronounced in patients with high body mass index (BMI) or other anatomical challenges, where the visibility and maneuverability of the device become restricted.

Moreover, modern medical practices demand secure handling of patient data, including the 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 review. The absence of proper encryption and password protection further increases the risk of unauthorized access to sensitive medical data.

Thus, there exists a need for a video laryngoscope that not only enhances the visual capabilities during intubation but also integrates advanced software features for data management, security, and ease of use.

Referring now to FIGS. 1, 2a, and 2b, a video laryngoscope (100) in accordance with the present invention is illustrated. The video laryngoscope (100) includes a handle (10), a blade (20), a display unit (30), and an attachment assembly (25) to attach the display unit (30) to the handle (10). The handle (10) is an elongated member that has an ergonomic design that allows clinicians to easily hold the handle (10) during an 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) to receive the attachment assembly (25).

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) that extends 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 comprises an electric circuit to transfer the visuals such as images and videos to the receiving port (12). Specifically, the camera channel (15) is electrically connected to a 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 comprising a camera housing (16). The camera housing (16) of the camera channel (15) is provided to capture visuals of the path of the endotracheal tube, larynx, trachea or airway.

Referring now to FIGS. 1, and 3, the camera housing (16) comprises an image sensor (161) and a light source (162). The image sensor (161) facilitates capturing of the visuals of the path of the endotracheal tube, larynx, trachea or airway. Specifically, an image sensor opening (1611) in the camera housing (16) allows the image sensor (161) to capture the visuals of the path of the endotracheal tube, larynx, trachea or airway. In the present aspect of the invention, the image sensor (161) is a 2-megapixel (MP) camera, but a person skilled in the art can use any other image sensor (161) having different specifications. For example, a person skilled in the art can configure the image sensor to meet different specifications, such as higher resolution sensors (e.g., 5 MP or 10 MP) for more detailed imaging. The image sensor may also include options for adjusting image brightness, contrast, and zoom functionality for a better visual of the intubation path.

Further, the camera housing (16) includes a light source opening (1621) to allow the light source (162) to illuminate the path of the endotracheal tube and the airway. Furthermore, the camera housing (16) has a deflector (18). Specifically, the deflector (18) is arranged on an outer surface of the camera housing (16) separating the image sensor opening (1611) and the light source opening (1621). The deflector (18) avoids the direct exposure of the light source (162) 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. It can be configured to emit varying intensities of light, depending on the clinical environment or patient anatomy. In particular, the light source is adjustable to illuminate dark or obscured areas, ensuring clear visibility during the intubation process.

In the present aspect of the invention, the deflector (18) is a rectangular strip as shown in FIG. 4. The rectangular strip is made up of a silicone material. A person skilled in the art can configure the deflector (18) with any other material, shape or size according to the size and position of the image sensor (161) and the light source (162). The deflector (18) is horizontally arranged between the light source opening (1621) and the image sensor opening (1611) to avoid the scattering of the light on the image sensor (161). Specifically, the deflector (18) is positioned between the light source (162) and image sensor (161) to minimize light scattering that can obscure or distort the visuals captured by the image sensor (161). The deflector is made from a silicone material, known for its light-absorbing properties, but other light-absorbing materials (e.g., polycarbonate or specialized plastic) can also be used. This ensures that the captured images are sharp and free from glare or halos that could obscure the clinician's view.

Referring now to FIGS. 3, and 4, the deflector (18) includes a rectangular portion (181), and two legs (182a, 182b) extending from the ends of the rectangular portion (181). The two legs (182a, 182b) are provided with respective locking elements (1821a, 1821b) to attach the deflector (18) to the camera housing (16). Specifically, the camera housing (16) has two openings (not shown) to receive the locking elements (1821a, 1821b) of the two legs (182a, 182b) to hold the deflector (18) on the outer surface of the camera housing (16). The deflector (18) is fixedly attached to the camera housing (16) using the locking elements (1821a, 1821b) but a person skilled in the art can provide the deflector (18) which is detachable from the camera housing (16). Specifically, the deflector (18) is detachable from the camera housing (16) if the deflector (18) has incurred damage or requires replacement.

In another aspect of the invention, the deflector (18) is an extruded portion (not shown) that extends from the outer surface of the camera housing (16). The extruded portion is provided between the image sensor opening (1611) and the light source opening (1621) to avoid direct light exposure to the image sensor (161) from the light source (162). The scattering of the light from the light source (162) makes images distorted and blurry. The deflector (18) avoids direct exposure of the light source (162) to the image sensor (161) to avoid distortion and blurriness of the images.

In another aspect of the invention, the deflector (18) is a thin sheet arranged between the image sensor opening (1611) and the light source opening (1621). The sheet can be made up of any material that absorbs light to avoid the direct exposure of the light source (162) on the image sensor (161).

Referring now to FIGS. 1, and 5, the display unit (30) is provided which is attachable to the handle (10) through the attachment assembly (25). The attachment assembly (25) includes a housing (27), and a second terminal (28) which is electrically connected to the display unit (30).

Specifically, the receiving port (12) has two openings to receive the respective ball projections (271a, 271b) of the housing (27) to securely hold the housing (27) within the receiving port (12) of the handle (10). The two ball projections (271a, 271b) ensure that the housing (27) is held in place until the two ball projections (271a, 271b) are pressed to detach the housing (27) of the attachment assembly (25). Specifically, the two ball projections (271a, 271b) have respective balls arranged at the extreme ends to easily press the two ball projections (271a, 271b) while detaching the housing (27) from the handle (10). The two ball projections (271a, 271b) are located on opposite sides of the housing (27). These ball projections 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 ball projections inward allows for quick detachment of the display unit (30). The ball projections are designed to operate with minimal force, allowing the clinician to quickly adjust or remove the display unit during an intubation procedure

Once the display unit (30) is attached to the handle (10) through the attachment assembly (25), the second terminal (28) of the attachment assembly (25) electrically connects with the first terminal (122) of the receiving port (12) of the handle (10) to establish the electric connection between the camera channel (15) and the display unit (30). Specifically, upon attaching the attachment assembly (25) to the handle (10), the first terminal (122) and the second terminal (28) immediately establish an electric connection between the image sensor (161) and the display unit (30) enabling the instantaneous display of visuals of the path of the endotracheal tube, larynx, trachea, or airway on the display screen (34).

Furthermore, the attachment assembly (25) includes a record button (271) (as shown in FIG. 5) to capture an image or record a video. In the present aspect of the invention, the record button (271) is arranged on a portion of the housing (27). However, a person skilled in the art can arrange the record button (271) on any other portion in such a way that the clinician's thumb easily reaches to the record button (271) to capture an image or record a video. The display unit (30) further includes an automatic image orientation correction feature (30a) as shown in FIGS. 7a-7b. When the display unit (30) is rotated downwards or upwards by approximately 180 degrees or other angles, the image on the display screen (34) automatically adjusts to ensure proper alignment for the clinician.

Referring now to FIGS. 9a-9c, in the present embodiment of the invention, the blade (20) is attachable to the handle (10) through an attachment mechanism (21) of the handle (10). The attachment mechanism (21) includes at least two ball projections (211a, 211b) arranged opposite to each other to securely attach and detach the blade (20) to the handle (10). The two ball projections (211a, 211b) are biased to radially extend away from the centre axis of the handle (10). The two ball projections (211a, 211b) are configured to engage with the blade (20). Specifically, the two ball projections (211a, 211b) are biased to extend radially outward from the center of the handle (10) using a biasing member (212) such as springs. The biasing member (212) is positioned inside the handle (10) and applies a continuous force to the ball projections (211a, 211b), to configure an extended position of two ball projections (211a, 211b) during the attachment of the blade (20). The two ball projections (211a, 211b) have corresponding biasing members (212a, 212b) to bias the two ball projections (211a, 211b) away from the handle (10) to engage and hold the blade (20) in an attached position. When the blade (20) is attached, the ball projections (211a, 211b) engage with corresponding openings (223a, 223b) in the blade (20), holding the blade (20) around the handle (10).

Referring now to FIG. 10, the blade (20) includes an attaching portion (251), a gripping portion (252), and a tongue portion (253). The attaching portion (251) is at the proximal end of the blade (20) and is adapted to attach the blade (20) to the handle (10). The attaching portion (251) includes at least two openings (223a, 223b) positioned to engage with the two ball projections (211a, 211b) of the handle (10). The two openings (223a, 223b) are provided to engage with the corresponding two ball projections (211a, 211b) during the intubation process. The attachment mechanism (21) allows the detachment of the handle (10) by pressing the two ball projections (211a, 211b) inward. The blade (20) has a first cavity (256) formed at the attaching portion (251) and the gripping portion (252) of the blade (20). The first cavity (256) is having a shape that is adapted to fit over the handle (10) and cover the handle (10) during the intubation process. The first cavity (256) allows the blade (20) to accommodate the handle (10) and remain firm in place during the intubation process. The first cavity (256) is formed at the attaching portion (251) and extends through the gripping portion (252).

The gripping portion (252) is a middle section of the blade and is arranged between the attaching portion (251) and the tongue portion (253). The gripping portion (252) is configured to provide a grip for the clinician during the intubation process. The gripping portion (252) has indentations (not shown) or other surface textures on the outer surface of the gripping portion (252) to enhance the grip of the clinician.

Furthermore, the tongue portion (253) is a distal end of the blade (20) located after the gripping portion (252). The tongue portion (253) is provided to interact with the patient's anatomy, particularly during intubation. In the present embodiment, the tongue portion (253) is an integral part of the blade (20) and transversally extends from the gripping portion (252). The tongue portion (253) is configured to receive the camera channel (15) and the camera housing (16). The tongue portion (253) includes a camera housing opening (165) to accommodate the camera housing (16) facing outside of the blade (20) allowing an image sensor (161) arranged within the camera housing (16) to capture visuals of the patient's airway, including the endotracheal tube, larynx, and trachea.

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 housing (16) therein. The second cavity (257) accommodates the camera channel (15), which runs along the length of the tongue portion (253). The second cavity (257) provides space for the camera channel (15) to be housed within the blade (20). Further, the camera housing (16) is exposed through the camera housing opening (165) arranged in the tongue portion (253) to allow the image sensor (161) to capture the visuals of the patient's airway.

After the intubation process, the blade (20) is detachable from the handle (10) by pressing the two ball projections (211a, 211b) against the biasing force exerted by the biasing members (212a, 212b). When the pressure to the two ball projections (211a, 211b) is applied, the two ball projections (211a, 211b) are pushed inward, overcoming the biasing force of the biasing members (212a, 212b) and moving toward the center of the handle (10) (as shown in FIG. 9b). The two ball projections (211a, 211b) are moved towards the center of the handle (10) to disengage from the corresponding openings (211a, 211b) in the blade (20), allowing the blade (20) to be detached from the handle (10). Particularly, upon pressing the two ball projections (211a, 211b), the blade (20) is slidable over the handle (10) and the camera channel (15) in a downward direction (shown in FIG. 9c), thereby completely removing the blade (20) from the handle (10) and disposing of it after the intubation process.

Further, the display unit (30) is placed inside the lower panel (42) of the display cover (40) and the upper panel (44) is pivoted to close the display cover (40). The flexible sheath is wrapped around the attachment assembly (25) and the portion of the handle (10). Once the flexible sheath is wrapped, the video laryngoscope (100) is ready to use for the intubation process. The display unit (30) is rotated to configure the position according to the clinician's requirement. The movement of the display unit (30) is facilitated by the hinge (26).

While performing the intubation process, the power button (32) is pressed to activate the display screen (34), the image sensor (161), and the light source (162). The visuals of the path of the endotracheal tube and the airway are displayed on the display screen (34). The deflector (18) of the camera housing (16) reduces the scattering of the light from the light source (162). The deflector (18) helps to reduce the distortion and blurriness of the images. Further, the record button (271) is provided to capture the image and record the video. The record button (271) is pressed and released to capture the image, and the record button (271) is pressed and held for 2 to 3 seconds to record the video. The video laryngoscope (100) is completely covered from the outside eliminating the risk of the video laryngoscope (100) getting infected. After the intubation process, the display cover (40) is removed from the display unit (30) and disposed of to avoid spreading infection. Further, the blade (20) is removed from the handle (10). The blade (20) which is mainly in contact with the body parts is disposed of after one use which helps to reduce the rate of infection or cross-contamination spread due to the repetitive use of the blade (20).

Further, the video laryngoscope (100) allows the clinician to have one hand free while operating the video laryngoscope (100) during the intubation process. In an operating room, clinicians need free hands to simultaneously use multiple devices or perform multiple actions. With the placement of the power button (32) at the bottom left of the display unit (30), the menu icon on the bottom left of the display screen (34) and the record button (29) under the display unit (30), the clinician can fully operate the video laryngoscope (100) with their left hand thus leaving the right hand free.

In another aspect of the present invention, the 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 attaching element (not shown) extending from a bottom portion of the display unit (30) to attach with the handle (10). It is obvious to a person skilled in the art to configure the attaching element of the display unit (30) to provide a threaded attachment or a snap-fit attachment or a similar attachment, to ensure a secure and functional connection between the display unit (30) and the handle (10).

Further, the video laryngoscope (100) includes a software module providing instructions that control the capture, display, storage, and transmission of visual data. The software module automatically initiates the recording of the procedure when the laryngoscope is activated and tags specific moments in the recording based on user input or automated criteria. The software module provides real-time analysis tools to assist in the identification of anatomical structures and potential obstructions during intubation

In an aspect as shown in FIG. 11, a computer implemented method (300) for operating a video laryngoscope in accordance with the present invention is provided. The video laryngoscope integrates software that improves its overall functionality, 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 the various operations of the video laryngoscope.

The method (300) starts at step 310.

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).

At step 330, The display unit (30) attached to the handle (10) is controlled to present visual data captured by a camera housing (16) located at the distal end of the handle (10). The display unit (30) functions as the primary interface between the clinician and the visual data generated during intubation procedures. The camera housing (16), positioned at the distal end of the handle (10), contains an image sensor (161) that captures real-time visuals of the patient's airway. These visuals are useful for guiding the clinician during the insertion of an endotracheal tube into the trachea.

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 housing (16) enables the clinician to view the pathway of the intubation, ensuring that the endotracheal tube is properly positioned within the airway.

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

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

At step 340, adjusting the orientation of the displayed visual data automatically based on the angle of the display unit (30) relative to the handle (10). The software manages the display of real-time visual data captured by the image sensor (161). In the present embodiment, orientation sensors are included within the laryngoscope (100) to detect the angle of the display unit (30) relative to the handle (10) and adjust the image accordingly. For instance, if the display unit (30) is rotated beyond 90° or 180°, the system automatically flips the image to ensure proper alignment. This is useful during procedures involving patients in challenging positions, as it maintains clear, upright visuals for the clinician.

Further at step 350, The visual data related to the endotracheal intubation procedure is captured and stored in a memory module within the display unit (30). The system allows clinicians to capture images and videos of the intubation process using a record button (29) arranged on the display unit (30). The captured data is stored in an integrated memory module. The software also allows for the automatic tagging of critical moments during the procedure, based on user inputs or predefined criteria, such as the detection of anatomical landmarks.

Further, at step 360, The clinicians can navigate through stored data using the touchscreen interface (TUI) of the display unit (30), allowing them to review, delete, or tag important visuals for later reference. This feature is helpful for post-procedural review, documentation, and data management, enhancing the overall utility of the device in clinical settings. Once the intubation procedure is complete, the video laryngoscope (100) allows clinicians to access and review the stored visuals. These may include both real-time images captured during the procedure and recorded videos. In an aspect, the TUI displays the files in an organized manner, for example, sorted chronologically or tagged by specific events, making it easy for clinicians to locate the exact moment they need to review.

In an aspect, using the TUI, clinicians can apply tags or labels to any significant moments, making it easier to retrieve them later. The tagging feature is customizable, allowing clinicians to use predefined tags (such as “difficult airway,” “anatomical marker,” or “tube placement”) or create their own custom tags relevant to the specific procedure.

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

The method ends at step 370.

Further, the system video laryngoscope (100) enables a secure connection to external devices for the transfer of visual data utilizing password-protected encryption. The video laryngoscope (100) has the capability to securely transfer visual data, such as images and videos captured during medical procedures, to external devices including computers, tablets, or external medical displays. This functionality allows for secure access to patient data while maintaining data integrity and compliance with healthcare data protection standards. The video laryngoscope (100) provides a password-protected encryption mechanism, ensuring that sensitive medical information is protected from unauthorized access during both storage and transmission.

Upon initiating a connection to 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, which may be user-defined for enhanced security. In one embodiment, the video laryngoscope (100) requires a six-digit password to unlock access to stored data or to initiate a data transfer to external devices. This prevents unauthorized personnel from accessing sensitive patient information.

Additionally, the video laryngoscope (100) can be configured to support multi-factor authentication (MFA) for heightened security. In this configuration, access to data and the ability to transfer visual data to external devices is restricted by requiring both a password and a secondary authentication factor. For instance, MFA may include biometric authentication, such as fingerprint scanning or facial recognition, or the use of a time-based one-time passcode (OTP) sent to a registered mobile device. This added layer of protection ensures that only authorized users can access or transfer the stored visual data.

Once the user has been authenticated, the visual data is encrypted prior to transfer. In an exemplary embodiment, the video laryngoscope (100) utilizes 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 transfer, it cannot be decrypted or accessed by unauthorized parties.

The encrypted data is then transmitted to external devices via both wired and wireless methods. In one embodiment, the video laryngoscope (100) supports wired connections, such as USB or HDMI, for data transfer to computers or larger display systems. In another embodiment, the video laryngoscope (100) supports wireless communication protocols, including Wi-Fi or Bluetooth, enabling real-time transfer of data to external medical equipment or displays.

In a wireless configuration, the video laryngoscope (100) can connect to external medical displays or hospital servers using password-protected encryption to ensure the security of patient data during transmission. This feature allows the clinician to display real-time visual data on larger screens or share it with other medical professionals during complex procedures. In another embodiment, the video laryngoscope (100) supports cloud-based storage, allowing for remote backup of visual data. The data transferred to the cloud is encrypted using the AES-256 encryption to protect patient privacy and ensure compliance with healthcare data regulations.

The video laryngoscope (100) also allows secure retrieval of cloud-stored data by authorized personnel. Access to this data requires password authentication or, where applicable, multi-factor authentication.

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

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 completed, the clinician initiates a data transfer to the hospital's server to store the visual data as part of the patient's medical records. The video laryngoscope (100) prompts the clinician to enter a password to authenticate 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 transfer process.

If the clinician requires access to this data from a remote location, the cloud-based storage option allows authorized personnel to retrieve the encrypted data by entering the appropriate password or passing multi-factor authentication. This secure connection ensures that only authorized users can access the patient's sensitive medical information.

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

In a preferred embodiment, the video laryngoscope (100) is used during the intubation of a high-BMI patient. The clinician attaches a Macintosh blade (20) to the handle (10) using the dual ball mechanism (21). The clinician rotates the display unit (30) by 180 degrees to avoid interference with the patient's chest, and the video laryngoscope (100) automatically adjusts the image orientation, maintaining an upright and clear view.

The clinician presses the record button (271) to capture the intubation process. The software tags critical moments, such as the tube's placement, based on predefined criteria. After the procedure, the clinician accesses the captured data through the TUI and reviews the tagged moments. The data is securely transferred to a hospital database using encrypted wireless communication, ensuring the patient's data is protected.

In another aspect, a non-transitory computer-readable medium storing program instructions executable by a processor of the video laryngoscope (100) in accordance with the present invention is provided.

The program instructions enable the 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 display's position. An on-screen indicator provides visual confirmation when the image orientation is adjusted.

The video laryngoscope (100) may include ambient light sensors that adjust the brightness and contrast of the display automatically, ensuring optimal visibility under various lighting conditions, including dimly lit or brightly illuminated environments.

To protect the visual data, the program includes encryption mechanisms that protect stored data from unauthorized access. Multi-factor authentication (MFA), such as a password and biometric input, is required to access stored data or connect to external devices. This ensures compliance with data security standards in healthcare.

The video laryngoscope (100) provides a customizable user interface that allows clinicians to create shortcuts for frequently used features, enhancing the system's usability during medical procedures. These shortcuts are configurable directly through the touchscreen.

The program instructions automatically initiate the recording of visual data when the laryngoscope is activated. Important/critical moments during the procedure are tagged based on predefined criteria or user input, ensuring efficient review and analysis later.

The video laryngoscope (100) supports wireless data transfer to external devices, ensuring secure communication through encrypted protocols. The video laryngoscope (100) also provides cloud-based backup for visual data, allowing remote access and retrieval by authorized personnel.

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.

Therefore, the present invention has the advantage of providing the video laryngoscope (100) to perform the intubation process. The video laryngoscope (100) is provided with the display unit (30) which rotates and moves in the back-and-forth direction to increase the visibility for the clinician. Further, the handle (10) of the video laryngoscope (100) is adapted to receive the adult blades as well as child blades, which reduces the other requirements like different handles for different blades or mountings to receive the different types of blades on the same handle (10). Further, the deflector (18) reduces the distortion and blurriness of the images for better quality visualisation. Furthermore, the handle (10) is covered by the blade (20) and the display unit (30) is covered by the display cover (40) which completely covers the video laryngoscope (100) and prevents the video laryngoscope (100) from getting infected during the intubation process. The video laryngoscope (100) ensures that the captured visuals are automatically adjusted based on the angle of the display unit relative to the handle. This eliminates the need for manual adjustments, allowing clinicians to maintain clear and upright visuals during intubation, particularly beneficial for patients in challenging positions or with high BMI. Further, the clinicians can easily capture and store visual data, such as images and videos, using the intuitive interface. The video laryngoscope automatically tags critical moments during procedures based on predefined criteria or user input, improving the organization of procedural records and facilitating post-procedural analysis.
