Description

Technical Field

[0001] The present invention relates to a laryngoscope device, and more particularly to a video laryngoscope. Background Art

[0002] A laryngoscope is a device, typically comprising a handle and a blade, that a clinician uses during endotracheal intubation. The laryngoscope assists in intubation by allowing the clinician to see the path of the endotracheal tube as it is passed through the glottis and into the trachea.

[0003] Currently, conventional video laryngoscopes come in two form factors. In the first form factor, the display is separated from the handle and attached to a cart. The display attached to the cart has limited operability. In addition, the display is 7 inches to 11 inches in size, and the cart is bulky and difficult to move. During intubation, clinicians need to look away from the patient and turn to the display attached to the cart, and not looking at the patient increases the risk of failure of the process. In addition, cart-based systems tend to be more expensive, and hospitals purchase some units to share between multiple operating rooms. This results in the inability to use a video laryngoscope in every intubation operation. In the second form factor, the display is attached to the handle, but the display is small, the image quality is poor, and it is inoperable. Both form factors increase patient risks and repeated intubations.

[0004] In addition, conventional video laryngoscopes include reusable blades that are used again and again for intubation procedures. The reuse of blades can lead to a higher risk of infection, increased operational burden on hospitals, and high ownership costs.

[0005] Conventional video laryngoscopes often utilize complex or cumbersome attachment systems between the display unit, handle, and blade. These mechanisms can include threaded connectors, magnetic fasteners, or bayonet mounts that can be difficult to operate, especially in high-pressure medical scenarios such as emergency intubation. A major concern with utilizing these attachment systems is that they can become misaligned or wear out over time. Repeated assembly and disassembly of components can degrade the precision of the connection, leading to unreliable performance during critical procedures. For example, improper alignment between the display and handle can cause fittings to become loose or unsecure, which can disrupt clinician workflow, cause delays, and increase the risk of complications for patients.

[0006] In addition, many current videolaryngoscope designs do not provide flexibility in the positioning and orientation of the display unit. These units are often fixed, forcing clinicians to adjust their body position or viewing angle to align the screen. In situations where rapid visualization of the airway is critical, this limitation can hinder the efficiency of the procedure. In addition, the inability to adjust the orientation of the video feed can make it difficult to obtain a clear view of the airway, especially in patients with challenging intubations or anatomical variations.

[0007] 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 cause interruptions in surgery as clinicians must frequently pause to operate the device, taking their attention away from the patient.

[0008] Therefore, there is a need for a video laryngoscope that overcomes some or all of the disadvantages of the prior art. Summary of the invention

[0009] According to the present invention, a video laryngoscope is provided. The video laryngoscope includes a handle designed to allow a clinician to hold the laryngoscope, the handle having an upper end and a lower end. The handle may feature a display unit attached to the upper end by an attachment assembly, a blade removably attachable about the handle, and a camera channel extending from the lower end. The camera channel may have a camera receptacle to capture visual data of the path of an endotracheal tube, larynx, trachea, or airway.

[0010] In some embodiments, the attachment assembly can connect the display unit to the handle via a hinge mechanism, enabling the display unit to rotate 360 ​​degrees to provide an optimal viewing angle during intubation. The blade can be attached to the handle via a double ball mechanism, wherein two spherical protrusions extend radially outward and engage openings in the blade, holding the blade in place until the spherical protrusions are pressed inward for removal.

[0011] The display unit may include a touch user interface that enables the clinician to interact with the 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 the display unit to display visual data captured by the image sensor even when detached.

[0012] In further embodiments, the handle may be adapted to accommodate both adult and pediatric blades without the need for additional adjustment, allowing the handle to fit a variety of patient types. The display unit may include a display screen for real-time vision, and a power button for turning the unit on or off. The video laryngoscope may include a memory and processor for storing and processing captured images and video, and an output port for connecting to an external display.

[0013] The display unit may also include features for flipping or rotating the displayed visuals controlled by a touch screen or arrow icons. To enhance data security, accessing stored visuals or connecting the display unit to an external device such as a personal computer (PC), Mac notebook, or tablet may require a password.

[0014] In additional embodiments, when the attachment assembly is mounted on the handle, the system may include an electrical connection established between the camera receptacle and the display unit, thereby enabling live transmission of visual data from the camera channel to the display screen.

[0015] A further aspect of the invention may provide an attachment assembly having dual protrusions arranged on the attachment assembly housing. These protrusions may engage with corresponding openings in a receiving port of the handle to secure the assembly until the protrusions are pressed inwardly for removal. The dual protrusions may include a spherical end and a protruding sleeve that engages with the handle to securely attach the display unit.

[0016] Additionally, the video laryngoscope may feature a display unit that automatically begins displaying visuals from the image sensor when turned on, eliminating the requirement to press a record button to initiate display of live visuals. The display unit may also be equipped with a record button that is pressed or held down during surgery to capture images or video accordingly.

[0017] In further embodiments, the system may be integrated with password protection for accessing stored images or videos, thereby ensuring secure data management. The system may also provide automatic connection between the camera channel and the display unit, allowing seamless image transfer when the display unit is attached to the handle.

[0018] The purpose of the present invention is to provide a video laryngoscope.

[0019] Another object of the present invention is to provide a video laryngoscope suitable for controlling nosocomial infection rates.

[0020] Yet another object of the present invention is to provide a video laryngoscope adapted to capture a clear and non-distorted image of the path of the endotracheal tube, larynx, trachea or airway.

[0021] It is a further object of the present invention to provide a video laryngoscope that provides the clinician with better visualization of the path of the endotracheal tube. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The present invention provides a video laryngoscope. The video laryngoscope is adapted to seamlessly attach and detach a display unit and a blade from a handle. The video laryngoscope is adapted to avoid blurring and distorted vision of the path of an endotracheal tube. Furthermore, the video laryngoscope is adapted to control infection rates spread by conventional laryngoscopes. Furthermore, the video laryngoscope allows a clinician to perform an intubation procedure without sacrificing visibility of the display unit.

[0034] The terms "first", "second", etc. herein do not indicate any order, quantity, or importance, but are used to distinguish one element from another, and the terms "one" and "an" herein do not indicate a limitation of quantity, but indicate the presence of at least one of the referenced items. The disclosed embodiments are merely examples of the present invention, which may be embodied in various forms.

[0035] Reference now Figure 1 , shows a video laryngoscope (100) according to the present invention. The video laryngoscope (100) is now referred to as "laryngoscope (100)". The laryngoscope (100) includes a display unit (30), an attachment assembly (25) and a handle (10).

[0036] The display unit (30) is configured to display visual information of the path of the endotracheal tube, larynx, trachea or airway. The display unit (30) is made into a rectangular design with a protective edge made of a flexible material to protect the display unit (30) from damage. It is obvious to a person skilled in the art that the display unit (30) can be configured of any shape or material as required. The display unit (30) includes a display screen (34) located in the center of the display unit (30). The display screen (34) is an LCD screen made of liquid crystal material, and the display screen (34) makes images and videos visible through conductors and electrode patterns. Specifically, the display screen (34) displays visual information of the path of the endotracheal tube, larynx, trachea or airway. In one embodiment, a person skilled in the art can configure a screen made of a quantum dot display. In another embodiment, an LED backlit LCD can be arranged in the display screen (34). In another embodiment, a WLCD, OLCD, plasma or OLED or its derivatives (transparent OLED, PMOLED, AMOLED) or micro LED, etc. can be arranged in the display screen (34). It will be apparent to one skilled in the art that any element or mechanism may be configured to present visual material to a clinician.

[0037] Reference now Figure 1 , Figure 3 and Figure 5The display unit (30) includes a battery (not shown) for powering the display unit (30) when in use. The battery can be a replaceable battery or a rechargeable battery, allowing the battery to be reused or replaced as needed. The display unit (30) also includes a power button (32) that allows the clinician to turn the display unit (30) on and off. The power button (32) is arranged on the lower side of the protective edge of the display unit (30), and the position of the power button (32) is within the range of the clinician's fingers, allowing the clinician to operate the power button (32) with only one hand. It is obvious to those skilled in the art that the power button (32) can be constructed anywhere on the display unit (30), allowing the clinician to operate the power button (32) with only one hand.

[0038] The display unit (30) also includes an output port (33). The output port (33) is provided on either side of the display unit (30) to connect 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 will be apparent to those skilled in the art that multiple output ports may be provided on the display unit (30) to allow the clinician to connect the display unit (30) to multiple external displays, or to allow the clinician to use the output port as a USB or charging port to charge the battery of the display unit (32).

[0039] The display unit (30) also includes a processor (not shown) and a memory (not shown) to process and store visual data of the path of the endotracheal tube, larynx, trachea or airway. The processor handles all functions of the laryngoscope (100), including all commands given by the clinician. The memory stores files for future reference by the clinician. A person skilled in the art can configure any processor as required, and can also arrange any capacity of memory as required.

[0040] The display screen (34) also includes a touch user interface (TUI) (not shown) integrated into the display screen (34). The display screen (34) allows the clinician to interact with the laryngoscope (100). The touch user interface of the display screen (34) is suitable for reviewing and managing previously recorded images or videos. The touch user interface includes a home page (not shown) showing the current time and date, a menu icon (not shown) for accessing multiple icons, and a battery icon (not shown) for indicating the battery level. The display screen (34) is turned on using the power button (32) to display the home page. 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.

[0041] In this embodiment of the present invention, the display unit (30) includes a charging light (35) arranged on the top of the protective edge of the display unit (30) to indicate the charging state of the battery. When the battery is connected to a power source while charging the battery, the charging light (35) is lit; and when the battery is not connected to a power source for charging, the charging light (35) is extinguished. It is obvious to those skilled in the art that the charging light (35) or any other element for indicating the charging state of the battery can be arranged, and the element can be arranged at any corner of the display unit (30).

[0042] The display unit (30) further includes a security password (not shown) to provide security for files previously stored in the memory of the display unit (30). The security password is required to open the file icon of the touch user interface. The clinician needs to enter the key password in the security password in order to access the files stored in the memory. In addition, the security password is required when the display unit (30) is connected to an external screen through the output port. The initial default password of the laryngoscope (100) is "000000". After opening the setting icon of the security password, the clinician can set any password within 6 digits.

[0043] The display screen (34) also includes arrows (not shown) for adjusting the visual orientation when using the laryngoscope (100), and the adjustable arrow feature allows the visual orientation to be flipped upside down as the situation requires. The clinician can interact with the display screen (34) and with arrows indicating adjustable directions arranged at the top and bottom of the display screen (34). After interacting with the arrows, the command goes to the processor, which processes the command and flips the display screen (34) visually vertically upside down. It will be apparent to those skilled in the art that any other icons or elements can be configured to adjust the visual data of the display screen (34) at any angle with any other icons not limited to arrows without interfering with the orientation of the display unit (30).

[0044] like Figure 1 and Figure 7As shown, 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 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 around 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 onto each other. In addition, the upper panel (44) has a flexible sheath (not shown) extending from the free end of the upper panel (44) to cover a portion of the attachment assembly (25) and the handle (10). The display cover (40) is disposable and can be disposed of once the intubation process is completed. In this embodiment, the display cover is a solid transparent material to protect the display unit from unnecessary scratches or damage. It is obvious to those skilled in the art that the display cover (40) can be configured to have any color, or to be constructed of any material, or to be solid or flexible as required.

[0045] In another embodiment of the present invention, the display cover (40) can also be made of a flexible transparent material, allowing the clinician to cover and expose the display unit (30) by stretchably placing the flexible transparent cover on the display unit (30). This flexible display cover does not have any snap-fit ​​arrangement structure, and the flexible display cover can be manually placed on the display unit (30).

[0046] Reference now Figure 1 and Figure 5 , the display unit (30) 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 provided to enable the display unit (30) to pivot in a front-to-back direction. The hinge (26) is connected to the display unit (30) and the housing (27).

[0047] The handle (10) is configured to allow a clinician to hold a laryngoscope (100), and 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), and the receiving port (12) has two openings (121a, 121b) opposite to each other for receiving an attachment assembly (25). The handle (10) is an elongated member having an ergonomic design, allowing a clinician to easily hold the handle (10) during intubation.

[0048] In addition, the housing (27) includes double protrusions (271a, 271b) extending from the outer surface of the housing (27). Each protrusion (271a, 271b) is arranged opposite to each other, with a compressible spring element (not shown) positioned inside the housing (27) between each other. The double protrusions (271a, 271b) securely attach the housing (27) to the handle (10) and remove the housing (27) from the handle (10). The double protrusions (271a, 271b) are biased to extend radially away from the central axis of the housing (27).

[0049] The housing (27) is attached to the receiving port (12) of the handle (10). Specifically, the receiving port (12) has two openings (121a, 121b) for receiving corresponding double protrusions (271a, 271b) of the housing (27) to securely hold the housing (27) in the receiving port (12) of the handle (10). The double protrusions (271a, 271b) ensure that the housing (27) is held in place until the double protrusions (271a, 271b) are pressed to remove the housing (27) of the attachment assembly (25). The diameter of the handle (10) is greater than the diameter of the housing (27) so as to securely receive the hose (27) in the upper end of the handle (10).

[0050] 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 handle (10) to establish an electrical connection between the display unit (30) and the handle (10). Specifically, after the attachment assembly (25) is attached to the handle (10), the second terminal (28) immediately establishes an electrical connection between 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).

[0051] Additionally, the attachment assembly (25) includes a record button (29) for capturing images or recording video (eg, Figure 5In the present embodiment of the present invention, the record button (29) is arranged on a part of the housing (27). However, those skilled in the art may arrange the record button (29) on any other part so that the clinician's thumb can easily reach the record button (29) to capture images or record videos.

[0052] The touch user interface is adapted to show an indication of the captured image on the display screen (34) when the clinician presses the record button (29) to capture the image. In addition, the touch user interface is adapted to display a recorded timer on the display screen (34) when the record button (29) is pressed and held to record the video. In addition, after pressing the record button (29), the recording is stopped and the timer disappears from the display screen (34). In an embodiment, the record button (29) can integrate multiple functions, which are not limited to recording images or videos. Those skilled in the art can configure the record button (29) on a display unit (30) having multiple features as required.

[0053] 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 includes a circuit for transmitting 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) (such as Figure 2b The camera channel (15) has a first end and a second end, the first end being connected to the tapered portion (14) of the handle (10), and the second end including a camera receiving portion (16). The camera receiving portion (16) of the camera channel (15) is provided to capture visual data of the path of the endotracheal tube, larynx, trachea or airway.

[0054] Reference now Figure 1 and Figure 3, the camera housing (16) is square and includes an image sensor (161) and a light source (162). It is obvious to those skilled in the art that the camera housing (16) can be configured into any shape and size as required. In this embodiment, the camera housing (16) includes an image sensor (161) and a light source (162). Those skilled in the art can arrange any number of image sensors (161) and light sources (162) as required. The image sensor (161) facilitates the capture of visual data of the path of the endotracheal tube, larynx, trachea or airway. Specifically, the image sensor opening (1611) in the camera housing (16) allows the image sensor (161) to capture visual data of the path of the endotracheal tube, larynx, trachea or airway. In this embodiment of the present invention, the image sensor (161) is a 2 million pixel (MP) camera, but those skilled in the art can use any other image sensor (161) with different specifications to capture visual data of the path of the endotracheal tube, larynx, trachea or airway.

[0055] In this embodiment, the display unit (30) is configured to establish a wireless connection with the handle (10), allowing the display unit (30) to display visual data from the image sensor (161) even when it is detached from the handle (10). It will be apparent to those skilled in the art that the display unit (30) can be connected to the image sensor (161) by configuring any mechanism or connection as required.

[0056] In addition, 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. In addition, the camera housing (16) has a deflector (18). Specifically, the deflector (18) is arranged on the outer surface of the camera housing (16) to separate 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).

[0057] In this embodiment of the present invention, the deflector (18) is a rectangular strip. The rectangular strip is made of silicone material. A person skilled in the art can construct 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 arranged horizontally between the light source opening (1621) and the image sensor opening (1611) to avoid scattering of light on the image sensor (161).

[0058] Now refer to Figure 3 and Figure 4The deflector (18) includes a rectangular portion (181) and two legs (182a, 182b) extending from both ends of the rectangular portion (181). The two legs (182a, 182b) are provided with corresponding locking elements (1821a, 1821b) to attach the deflector (18) to the camera accommodating portion (16). Specifically, the camera accommodating portion (16) has two openings (not shown) to receive the locking elements (1821a, 1821b) of the two legs (182a, 182b), thereby retaining the deflector (18) on the outer surface of the camera accommodating portion (16). The deflector (18) is fixedly attached to the camera accommodating portion (16) using the locking elements (1821a, 1821b). The two legs (182a, 182b) have a cylindrical shape extending from both ends of the rectangular portion (181). The shape of the locking elements (1821a, 1821b) is such that the diameter of the locking elements (1821a, 1821b) facing the rectangular portion (181) is larger, and the other end of the locking elements (1821a, 1821b) has the same diameter as the two legs (182a, 182b). The two legs (182a, 182b) and the locking element (1821a, 1821b) are made of a flexible material. After the deflector (18) is pressed into the opening of the camera accommodating portion (16), the locking element (1821a, 1821b) slides in the opening. Since the other end of the locking element (1821a, 1821b) has the same diameter as the two legs (182a, 182b) and the opening, and the other end of the locking element (1821a, 1821b) with a larger diameter is compressed and slides into the opening of the camera accommodating portion (16), the deflector (18) is locked on the camera accommodating portion (16). The deflector (18) can be removed from the camera accommodating portion (16). Specifically, if the deflector (18) is damaged or needs to be replaced, the deflector (18) can be removed from the camera accommodating portion (16).

[0059] In another embodiment of the present invention, the deflector (18) is an extrusion portion (not shown) extending from the outer surface of the camera housing (16). An extrusion portion is provided between the image sensor opening (1611) and the light source opening (1621) to prevent light from the light source (162) from being directly exposed to the image sensor (161). The scattering of light from the light source (162) causes image distortion and blurring. The deflector (18) prevents the light source (162) from being directly exposed to the image sensor (161), thereby preventing image distortion and blurring.

[0060] In another embodiment of the present invention, the deflector (18) is a thin plate arranged between the image sensor opening (1611) and the light source opening (1621). The plate can be made of any material that absorbs light to avoid direct exposure of the light source (162) to the image sensor (161). It is obvious to a person skilled in the art that the deflector (18) can be constructed in any shape and any material, and can be constructed with any orientation to avoid direct exposure of the light source (162) to the image sensor (161), thereby avoiding distortion and blurring of the image.

[0061] Reference again Figure 1 and Figure 2a , the handle (10) is adapted to receive the 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). When performing the intubation process, the blade (20) is attached to the handle (10). The handle is adapted to receive all types of blades (20), such as Macintosh blades and Miller blades. 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 adults and children, such as Macintosh blades and Miller blades. The handle (10) does not require any other adjustment device or mounting device to receive adult blades and pediatric blades. The blade (20) can slide on the camera channel (15) and be attached to the handle (10) to perform the intubation process. The blade (20) is attached to the handle (10) in a detachable manner and can be removed from the handle (10) after the intubation process.

[0062] In this embodiment of the present invention, the blade (20) is 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) arranged opposite to each other on the outer surface of the handle and adjacent to the double protrusions (271a, 271b), which are used to firmly attach the blade (20) to the handle (10) and remove the blade (20) from the handle (10). The double ball mechanism (211a, 211b) is biased to extend radially away from the central axis of the handle (10). The double ball mechanism (211a, 211b) engages with the blade (20). Specifically, the blade (20) has two openings (not shown) that 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) is held in place until the two spherical protrusions (211a, 211b) are pressed to remove the blade (20).

[0063] The double ball mechanism (21) has a spring (not shown) attached between each other, and the double ball mechanism (21) is biased and extends in opposite directions relative to the central axis of the handle (10). When the blade (20) is placed on the handle (10), the double ball mechanism (21) is compressed in the direction of the central axis of the handle (10), and when the opening of the blade (20) is aligned with the double ball mechanism (21), the double ball mechanism (21) extends away from the central axis of the handle (10) and engages with the opening to lock the blade (20) on the handle (10). In order to remove the blade (20) from the handle (10) and the camera receiving portion (16) of the laryngoscope (100), the clinician only needs to press the double ball mechanism (21) toward the central axis of the handle (10), and the double ball mechanism (21) will disengage from the opening of the blade (20), thereby removing the blade (20) from the laryngoscope (100).

[0064] 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 can be spread by repeated use of the same blade (20).

[0065] Since the top of the blade (20) covers the handle (10) of the laryngoscope (100) and the bottom covers the camera channel (15) and the camera receiving portion (16), the shape of the blade starting from the bottom end is the same as the shape of the camera channel (15). The blade (20) has two bottom ends, the first bottom end serves as a guide for the laryngoscope (100) when the laryngoscope (100) is located in the path of the endotracheal tube, larynx, trachea or airway, and the second bottom end has an opening (165) similar in shape to the camera receiving portion (16). The opening (165) allows the image sensor (161) and the light source (162) to capture visual data of the path of the endotracheal tube. The image sensor (161) captures visual data of the path of the endotracheal tube, larynx, trachea or airway and transmits the visual data to the display unit (30).

[0066] Before performing the intubation procedure, 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 over the camera channel (15) and is attached to the handle (10) by a double ball mechanism (21) of the handle (10).

[0067] When performing an intubation procedure, 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 endotracheal tube path and airway are displayed on the display screen (34). The deflector (18) of the camera housing (16) reduces the scattering of light from the light source (162). The deflector (18) helps to reduce distortion and blurring of the image. In addition, a record button (29) is provided for capturing images and recording videos. The record button (29) is pressed and released to capture images, and the record button (29) is pressed and held for 2 to 3 seconds to record videos. The video laryngoscope (100) is completely covered from the outside, eliminating the risk of infection of the video laryngoscope (100). After the intubation procedure, the display cover (40) is removed from the display unit (30) and disposed of to avoid spreading infection. In addition, the blade (20) is removed from the handle (10). The blade (20) that mainly contacts the body part is disposed after being used once, which helps to reduce the infection rate or cross-contamination transmission rate caused by repeated use of the blade (20).

[0068] In addition, the video laryngoscope (100) allows the clinician to free one hand when operating the video laryngoscope (100) during intubation. In the operating room, the clinician needs to free both 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 unit (30), and placing the record button (29) below the display unit (30), the clinician can operate the video laryngoscope (100) completely with the left hand, thereby freeing up the right hand.

[0069] In another embodiment of the present invention, the video laryngoscope (100) comprises 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) comprises an attachment element (not shown) extending from a bottom portion of the display unit (30) to attach to the handle (10). It will be apparent to a person skilled in the art that the attachment element of the display unit (30) can be configured to provide a threaded attachment or a snap-on attachment or a similar attachment to ensure a secure and functional connection between the display unit (30) and the handle (10).

[0070] Reference now Figure 5 and Figure 6, a second embodiment of the present invention. The display unit (30) is configured to be able to 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 provided for pivoting the display unit (30) in a front-to-rear direction. The hinge (26) is connected to the display unit (30) and the housing (27). Specifically, the hinge (26) includes a horizontal socket (not shown), and a horizontal shaft (not shown) is attached to the lower end of the display unit (30), and the horizontal shaft and the horizontal socket are combined with each other so that the horizontal shaft can rotate around a horizontal axis in the horizontal socket, thereby allowing the display unit (30) to be adjusted / moved vertically. In addition, the horizontal socket of the hinge (26) includes a vertical axis, which is constructed on the bottom central part, and the top end of the vertical axis is attached to the bottom central part of the horizontal socket, thereby allowing the vertical axis to rotate around the vertical axis in the bottom central part, and the lower end of the vertical axis is combined on the top end of the shell (27), and the vertical axis is connected to the second terminal (28), thereby electrically connecting the display unit (30) with the second terminal (122).

[0071] Rotation of the vertical axis about the vertical axis allows the display unit (30) to be adjusted horizontally about the vertical axis, so that the hinge (26) allows the display unit (30) to be adjusted vertically and horizontally as required. The housing (27) receives the vertical axis 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 to provide better visibility for the clinician. The clinician can adjust the display unit (30) on the housing (27) in a vertical or horizontal direction as required. In this embodiment, the mechanism of the hinge (26) is arranged to allow the display unit (30) to be adjusted to any desired angle. It will be apparent to those skilled in the art that any other mechanism can be constructed to allow the display unit (30) to be adjusted in any orientation as required.

[0072] In a further embodiment, a ball joint may be arranged to allow rotation and movement in multiple directions as required. In a further embodiment of the invention, a universal joint may be arranged, which consists of two hinged parts connected by a cross axis, allowing rotation and movement of the display unit (30) on two axes, providing an adjustable display unit as required. In a further embodiment of the invention, a gimbal mechanism commonly used for stabilizing cameras may be arranged, allowing free movement in three axes of pitch, yaw and roll. The gimbal mechanism will provide adjustable movement for the display unit (30) at all angles.

[0073] In another embodiment of the present invention, a swivel joint may be arranged between the display unit (30) and the housing (27), which enables the display unit (30) to pivot horizontally and vertically around a center point. It will be apparent to those skilled in the art that any alternative mechanism may be constructed to provide the display unit (30) with adjustable movement relative to all angles.

[0074] The handle (10) is configured to allow a clinician to hold a laryngoscope (100), and 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), and the receiving port (12) has two openings (121a, 121b) opposite to each other for receiving an attachment assembly (25). The handle (10) is an elongated member having an ergonomic design, allowing a clinician to easily hold the handle (10) during intubation.

[0075] In addition, the housing (27) includes a double protrusion (271a, 271b) having two spherical protrusions (271a, 271b) extending from the outer surface of the housing (27). The double protrusions (271a, 271b) are arranged opposite to each other, with a compressible spring element (not shown) arranged inside the housing (27) between them. The double protrusions (271a, 271b) firmly attach the housing (27) to the handle (10) to remove the housing (27) from the handle (10). The double protrusions (271a, 271b) are biased to extend radially away from the central axis of the housing (27).

[0076] The housing (27) is attached to the receiving port (12) of the handle (10). Specifically, the receiving port (12) has two openings (121a, 121b) for receiving the double protrusions (271a, 271b) of the housing (27) to securely hold the housing (27) in the receiving port (12) of the handle (10). The double protrusions (271a, 271b) ensure that the housing (27) is held in place until the double protrusions (271a, 271b) are pressed to remove the housing (27) of the attachment assembly (25). The diameter of the handle (10) is greater than the diameter of the housing (27) so as to securely receive the housing (27) in the top end of the handle (10).

[0077] Specifically, the double protrusions (271a, 271b) have corresponding spheres arranged at two extreme ends, and the double protrusions (271a, 271b) include protruding rings arranged near the positions of the spheres. When the attachment assembly (25) is placed in the handle (10), the double protrusions (271a, 271b) are compressed by the inner wall of the top end of the handle (10). The receiving port (12) is arranged at a predetermined distance from the top end of the handle (10). When the double protrusions (271a, 271b) are aligned with the receiving port (12), the double protrusions (271a, 271b) extend in radially opposite ways relative to the central axis of the housing (27) and pass through the receiving port (12), and the protruding rings engage with the receiving port (120) of the handle (10), thereby firmly attaching the display unit (30) to the handle (10). It is obvious to those skilled in the art that any alternative mechanism can be constructed to attach the display unit (30) to the handle (10).

[0078] In order to remove the display unit (30) from the handle (10), it is necessary to press the double protrusions (271a, 271b) toward the central axis of the shell (27). When the double protrusions (271a, 271b) are pressed toward the central axis of the shell (27), the protruding ring disengages from the receiving port (12), and the compressible spring element is compressed toward the central axis of the shell (27) to disengage the double protrusions (271a, 271b) from the receiving port (12) of the handle (10), allowing the display unit (30) to be removed from the handle (10).

[0079] In another aspect of the invention, a bayonet mounting mechanism may be disposed between the housing (27) and the top end of the handle (10), characterized by a pin or tab that locks into a slot via a twist-lock motion, and a clinician may rotate a portion thereof to engage or disengage the handle (10) from the display unit (30).

[0080] In one aspect of the present invention, a magnetic fastener may be arranged between the housing (27) and the top end of the handle (10) for attaching and detaching the display unit (30) from the handle (10). In another embodiment of the present invention, an interlocking tab may be arranged between the bottom end of the housing (27) and the upper end of the handle (10). The housing (27) has a flexible or rigid tab, and the top end of the handle (10) has a slot. The tab snaps into the slot for attaching and detaching the housing (27) from the handle (10), and the clinician must press the card inward to remove the tab from the slot of the handle (10) to release the housing (27) of the display unit (30).

[0081] In another aspect of the present invention, a threaded mechanism may be arranged between the housing (27) and the handle (10), allowing the clinician to attach and detach the housing (27) from the handle (10) by engaging and disassembling the threaded mechanism. It is obvious to those skilled in the art that any mechanism not limited to the above disclosure may be constructed to attach and detach the housing (27) from the upper end of the handle (10), or to attach to any other device having a receiving port (12).

[0082] After the display unit (30) is attached to the handle (10) by the attachment assembly (25), the second terminal (28) of the attachment assembly (25) is electrically connected to the handle (10) to establish an electrical connection between the display unit (30) and the handle (10). Specifically, after the attachment assembly (25) is attached to the handle (10), the second terminal (28) immediately establishes an electrical connection between the display unit (30) and the image sensor (161), so that visual information of the path of the endotracheal tube, larynx, trachea or airway can be instantly displayed on the display screen (34).

[0083] Reference now Figure 7 and Figure 8 , a third embodiment of the present invention. A display unit (30) is provided, and the display unit (30) can be attached to the top of the handle (10) through an attachment assembly (25). The handle (10) is configured to allow a clinician to hold a laryngoscope (100), and the handle (10) includes a receiving port (12), and the receiving port (12) has two openings (121a, 121b) opposite to each other. The handle (10) is an elongated member, and the elongated member has an ergonomic design, allowing the clinician to easily hold the handle (10) during intubation.

[0084] The image sensor (161) is arranged on the camera housing (16), and the camera housing (16) is attached to the lower end of the handle (10) through the camera channel (15). The image sensor (161) facilitates capturing visual data of the path of the endotracheal tube, larynx, trachea or airway. Specifically, the image sensor opening (1611) provided in the camera housing (16) allows the image sensor (161) to capture visual data of the path of the endotracheal tube, larynx, trachea or airway. In the present embodiment, the image sensor (161) is a 2 million pixel (MP) camera, but a person skilled in the art may use any other image sensor (161) with different specifications to capture visual data of the path of the endotracheal tube, larynx, trachea or airway.

[0085] In addition, 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. In addition, the camera housing (16) has a deflector (18). Specifically, the deflector (18) is arranged on the outer surface of the camera housing (16) to separate 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).

[0086] The display unit (30) is configured to display visual information of the path of the endotracheal tube, larynx, trachea or airway. The display unit (30) is rectangular in design and has a protective edge made of a flexible material to protect the display unit (30) from damage. It is obvious to a person skilled in the art that the display unit (30) can be configured in any shape or material as required. The display unit (30) includes a display screen (34) located in the center of the display unit (30). The display screen (34) is an LCD screen made of liquid crystal material. The display screen displays images and videos through conductors and electrode patterns, specifically, the screen displays visual information of the path of the endotracheal tube, larynx, trachea or airway.

[0087] The display unit (30) also includes an output port (33). The output port (33) is provided on either side of the display unit (30) to connect 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 will be apparent to those skilled in the art that multiple output ports may be provided on the display unit (30) to allow the clinician to connect the display unit (30) to multiple external displays or to use the output ports as USB or charging ports to charge the battery of the display unit (32).

[0088] The display unit (30) also includes a processor (not shown) and a memory (not shown) to process and store visual data of the path of the endotracheal tube, larynx, trachea or airway. The processor processes all functions of the laryngoscope (100), including all commands given by the clinician. The memory stores files for future reference by the clinician. Those skilled in the art can configure any processor as required and can also set a memory with any capacity as required.

[0089] The display screen (34) also includes a touch user interface (TUI) (not shown) integrated into the display screen (34). The display screen (34) allows the clinician to interact with the laryngoscope (100). The touch user interface of the display screen (34) is suitable for reviewing and managing previously recorded images or videos. The touch user interface includes a home page (not shown) for showing the current time and date, a menu icon (not shown) for accessing multiple icons, and a battery icon (not shown) for indicating the battery power. The display screen (34) is turned on using the power button (32) to display the home page. 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), allowing the clinician to reach the menu icon with one hand.

[0090] The plurality of icons are assigned specific actions to be executed upon receiving a command from a processor of the display unit (30). Specifically, the plurality of icons include a setting icon (not shown) for changing the brightness of the display screen (34), the volume of the sound, opening or closing the output port (33), etc. In addition, the plurality of icons include a photo icon (not shown) for viewing and managing previously recorded images, and a video icon for viewing and managing previously recorded videos. In another embodiment of the present invention, the plurality of icons include a folder icon (not shown) for viewing and managing previously recorded images and videos in one place. Those skilled in the art can add as many icons as possible related to different functions as required.

[0091] In an embodiment of the present invention, the display unit (30) includes a charging light (35) arranged at the top of the protective edge of the display unit to indicate the charging state of the battery. When the battery is connected to a power source to charge the battery, the charging light (35) is lit; when the battery is not connected to a power source to charge, the charging light (35) is extinguished. It is obvious to those skilled in the art that the charging light (35) or any other element for indicating the charging state of the battery can be arranged, and the element can be arranged at any corner of the display unit (30).

[0092] In this embodiment, the display unit (30) automatically begins displaying visual data from the image sensor (161) when turned on and connected to the handle (10), eliminating the requirement to press the record button (29) to initiate display of live visual data. The circuit between the display unit (30) and the camera housing (16) implemented by the first terminal (122) at the bottom end of the handle (10) and the second terminal (28) at the top end of the handle (10) allows the display unit (30) to show and record live visual data without the use of the record button (29). It will be apparent to those skilled in the art that any alternative means may be configured to display visual data of the path of the endotracheal tube, larynx, trachea or airway and record the visual data.

[0093] Additionally, the clinician can capture a still image with a single press and record a video by a press and hold action on the record button (29), with a visual timer displayed on the display unit during the video recording. It will be apparent to one skilled in the art that a recode button (29) can be constructed with multiple features to operate the display unit (30).

[0094] The display unit (30) also includes a security password (not shown) to provide security for files previously stored in the memory of the laryngoscope (100). The security password is required to open the file icon of the touch user interface. The clinician needs to enter the key password in the security password in order to access the files stored in the memory. In addition, the security password is also required when connecting the display unit (30) to an external screen through the output port. The initial default password of the laryngoscope (100) is "000000". After opening the setting icon of the security password, the clinician can set any password within 6 digits.

[0095] In a further embodiment of the invention, a security password may be required to open the laryngoscope (100). In a further embodiment of the invention, a security password may be required to transfer the recorded file from the memory of the laryngoscope (100) to another device. In a further embodiment, a biometric authentication system (fingerprint, face, iris or retina, voice, palm or vein) may be set to access or transfer the recorded file. In a further embodiment, a pattern mechanism may be set to access or transfer the recorded file. In a further embodiment, a two-factor authentication may be set within the display unit to access or transfer the recorded file. In a further embodiment, a hardware security key (USB or NFC key) may be set to access or transfer the recorded file. In a further embodiment, behavioral biometrics (the clinician's unique typing rhythm and speed, the way the clinician moves the mouse or interacts with the touch screen) may be set, or a token-based authentication using a hardware or software token to generate a unique code may be set, such as an RSA token or an authentication application or gesture recognition to authenticate the user through specific gestures made in front of a camera or using hand movements on a touch screen. Alternatively, a proximity-based authentication may be provided, whereby when a trusted device (such as a smartphone or smartwatch) approaches, the proximity-based authentication uses Bluetooth to unlock the device. It will be apparent to those skilled in the art that a security password may be configured at any function of the laryngoscope (100) as required. In addition, those skilled in the art may also configure any security mechanism to protect the recorded files.

[0096] In addition, the display screen (34) also includes arrows (not shown) for adjusting the orientation of the visuals when using the laryngoscope (100), the arrow feature allowing the orientation of the visuals to be flipped upside down as required by the situation. The clinician can interact with the display screen (34), and arrows indicating adjustable directions are provided at the top and bottom of the display screen (34). After interacting with the arrows, the command is passed to the processor, which processes the command and flips the visuals of the display screen (34) upside down in the vertical direction. It will be apparent to those skilled in the art that any other manner may be configured to adjust the visuals of the display screen (34) to any angle without interfering with the orientation of the display unit (30) using any other icons other than arrows.

[0097] In this embodiment of the invention, the display screen (34) is provided with arrows which allow the display screen (34) to be adjusted to flip horizontally as required without disturbing the orientation of the display unit (30).

[0098] In another embodiment of the present invention, the display screen (34) may be configured with a visual adjustment feature without any icons such as arrows, and the clinician may interact with the display screen (34) using only fingers and rotate the orientation of the visuals using the fingers. In another embodiment of the present invention, the laryngoscope (100) may be intelligent enough to receive voice commands from the clinician to adjust the orientation of the visuals on the display screen (34). It will be apparent to those skilled in the art that any feature or icon or not limited to icons may be configured to adjust the orientation of the visuals on the display screen (34) without interfering with the orientation of the display unit (30).

[0099] like Fig. 9 As shown, 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 obstruction.

[0100] Therefore, the present invention has the advantage of providing a video laryngoscope (100) to perform an intubation procedure. The video laryngoscope (100) is provided with a display unit (30) that rotates and moves in a front-to-back direction to increase visibility for the clinician. In addition, the handle (10) of the video laryngoscope (100) is suitable for receiving adult blades and pediatric blades, thereby reducing 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 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 being infected during the intubation process.
