VIDEO LARYNGOSCOPE

TECHNICAL FIELD

The present invention relates to a laryngoscopy device. More particularly, the present invention relates to a video laryngoscope.

BACKGROUND

A laryngoscope is a device, typically comprising a handle and a blade, which is used by clinicians during endotracheal intubation. The laryngoscope assists with intubation by allowing the clinician to visualise the path of the endotracheal tube as the laryngoscope passes through the glottis towards the trachea.

Presently, traditional video laryngoscopes come in two form factors. In the first form factor, the display is detached from the handle and is attached to a cart. The display attached to the cart has a limited manoeuvrability. Also, the size of the display is 7-11 inches and the carts are bulky and hard to move around. While performing the intubation process, the clinician needs to look away from the patient and towards the display which is attached to the cart and not looking at the patient increases the risk of a failed process. In addition, cart-based systems tend to be more expensive and hospitals purchase a few units to be shared between multiple operating rooms. This results in the video laryngoscope not being available for every intubation procedure. In the second form factor, the display is attached to the handle but the displays are small, have poor image quality and are not manoeuvrable. Both form factors result in increased risk to the patient and repeated intubations.

Further, traditional video laryngoscope includes reusable blades that are used again and again for the intubation process. Repeated use of the blades leads to a higher risk of infection, increased operational burden on hospitals and high ownership costs.

Traditional video laryngoscopes often employ complex or cumbersome attachment systems between the display unit, handle, and blade. These mechanisms, which may include threaded connections, magnetic fasteners, or bayonet mounts, can be difficult to operate, especially in high-pressure medical scenarios such as emergency intubations. One major issue with these attachment systems is their potential for misalignment or wear over time. Repeated assembly and disassembly of the components can degrade the precision of the connection, leading to unreliable performance during critical procedures. For example, improper alignment between the display and the handle may result in loose or unstable fittings, which can disrupt the clinician's workflow, causing delays and increasing the risk of patient complications.

Moreover, many current video laryngoscope designs fail to provide flexibility in the positioning and orientation of the display unit. These units are often fixed in place, forcing clinicians to adjust their body position or viewing angle to align with the screen. In scenarios where rapid visualization of the airway is critical, such limitations can hinder the efficiency of the procedure. Furthermore, the inability to adjust the orientation of the video feed can make it difficult to obtain a clear view of the airway, particularly in challenging intubations or in patients with anatomical variations.

Existing designs also tend to lack user-friendly control interfaces, often requiring clinicians to interact with multiple buttons to operate the display, adjust settings, or capture images. This complexity can lead to interruptions during the procedure, as clinicians must frequently pause to manipulate the device, taking their focus away from the patient.

Therefore, there is a need for a video laryngoscope, which overcomes few or all drawbacks of the prior art.

STATEMENT OF THE INVENTION

According to the present aspect of the invention, there is provided a video laryngoscope. The video laryngoscope includes a handle designed to allow a clinician to hold the laryngoscope, with an upper end and a lower end. The handle may feature a display unit attachable to the upper end through an attachment assembly, while a blade may be removably attached around the handle and a camera channel extending from the lower end. The camera channel may have a camera housing to capture visuals of the path of the endotracheal tube, larynx, trachea, or airway.

In some embodiments, the attachment assembly may connect the display unit to the handle through a hinge mechanism, enabling 360-degree rotation of the display unit to provide optimal viewing angles during intubation. The blade may be attached to the handle via a dual ball mechanism, where two ball projections extend radially outward and engage with openings in the blade, holding the blade in place until the ball projections are pressed inward for detachment.

The display unit may include a touch user interface, enabling clinicians to interact with stored images and videos, configure settings such as brightness, sound, and output port controls, and review captured visual data. The display unit may also establish a wireless connection with the handle, allowing it to display visuals captured by the image sensor even when detached.

In another embodiment, the handle may be adapted to receive both adult and pediatric blades without requiring additional adjustments, making it suitable for various patient types. The display unit may include a display screen for real-time visuals, and a power button to turn the unit ON or OFF. The video laryngoscope may include a memory and processor to store and process captured images and videos, as well as an output port for connecting to external displays.

The display unit may also include a feature for flipping or rotating the displayed visuals, controlled through a touchscreen or an arrow icon. For enhanced data security, a passcode may be required to access stored visuals or to connect the display unit to external devices, such as PCs, Macs, or tablets.

In a further embodiment, the system may include an electrical connection established between the camera housing and the display unit when the attachment assembly is mounted on the handle, enabling live transmission of visuals from the camera channel to the display screen.

Another aspect of the invention may provide an attachment assembly with dual projections arranged on the attachment assembly housing. These projections may engage with corresponding openings in the receiving port of the handle, securing the assembly until the projections are pressed inward for detachment. The dual projections may include ball ends and protruded sleeves that engage with the handle to securely attach the display unit.

Additionally, the video laryngoscope may feature a display unit that automatically starts displaying visuals from the image sensor upon being powered on, eliminating the need for pressing a record button to initiate the display of live visuals. The display unit may also be equipped with a record button to capture images or videos during the procedure by pressing or holding the button, respectively.

In another embodiment, the system may incorporate passcode protection to access stored images or videos, ensuring secure data management. The system may also provide an automatic connection between the camera channel and display unit, allowing for seamless image transmission when the display unit is attached to the handle

The clinician needs to put a key passcode in the security passcode in order to access the stored files within the memory. Further, the security passcode is also required upon connecting the display unit (30) with an external screen through the output port. The laryngoscope (100) initially comes with the default passcode which is “000000”, the clinician can set any passcode within the 6 digits upon opening the setting icon of the security passcode.

In another embodiment of the present invention, the security passcode may be required for turning ON the laryngoscope (100). In another embodiment of the present invention, the security passcode may be required to transfer the recorded files from the memory of the laryngoscope (100) to another device. In another embodiment, a biometric authentication system (fingerprint, facial, iris or retinal, voice, palm or vein) may be arranged to access or transfer the recorded file. In another embodiment, a pattern mechanism may be arranged to access or transfer the recorded files. In another embodiment, two-factor authentication may be arranged within the display unit to access or transfer the recorded file. In another embodiment, a hardware security keys (USB or NFC keys), to access or transfer the recorded files. In another embodiment, behavioural biometrics (clinician's unique typing rhythm and speed, the way clinician move their mouse or interact with touchscreens) or a token-based authentication which uses a hardware or software token that generates unique codes for examples include RSA tokens or authenticator apps or gesture recognition may arranged to authenticates users through specific gestures made in front of the camera or using hand motions on a touch screen, or a proximity-based authentication may be arranged that uses Bluetooth to unlock a device when a trusted device (such as a smartphone or smartwatch) is near, or the like. It is obvious for the person skilled in the art to configure security passcode at any function of the laryngoscope (100) as per the requirement. Further, the person skilled in the art can also configure any security mechanism to secure the recorded files.

Moreover, the display screen (34) also includes an arrow (not shown) for adjusting the visual orientation while using the laryngoscope (100), the arrow feature allows for flipping visual orientation upside down as per the requirement of the situation. The clinician can interact with the display screen (34), and the arrow directing the adjustable direction is arranged on a top and bottom of the display screen (34). Upon interaction with the arrow, the commands go to the processor and the processor processes the commands and flips the display screen (34) visual vertically upside down. It is obvious for the person skilled in the art to configure any other way to adjust the visuals of the display screen (34) with any other icon not limited to the arrow, at any angle without disturbing the orientation of the display unit (30).

In the present embodiment of the invention, the display screen (34) is configured with the arrow that allows the adjustment of the display screen (34) to flip horizontally as per the requirement, without disturbing the orientation of the display unit (30).

In another embodiment of the present invention, the display screen (34) may be configured with the visual adjustment features without any icon such as arrow, the clinician can just interact with the display screen (34) with fingers and rotate the visual orientation with fingers. In another embodiment of the present invention, the laryngoscope (100) may be smart enough to take voice commands from the clinician to adjust the orientation of the display screen (34) visuals. It is obvious for the person skilled in the art to configure any features or icon or not limited to icon to adjust the visual orientation of the display screen (34) without disturbing the display unit (30) orientation.
