Description

Technical Field

[0001] The present invention relates to a laryngoscope device. More particularly, the present invention relates to a videolaryngoscope. Background Art

[0002] A laryngoscope is a device typically comprising a handle and a blade used by a clinician during endotracheal intubation. A laryngoscope aids in intubation by allowing the clinician to visualize the path of the endotracheal tube as the laryngoscope is passed through the glottis toward the trachea.

[0003] Intubation is the process of inserting a tube called an endotracheal tube through the mouth and then into the airway. Intubation is a necessary procedure before any surgery that requires the patient to be given general anesthesia. Intubation is also done for patients who need to use a ventilator to assist with breathing. The endotracheal tube is connected to an anesthesia system or ventilator that pushes air into the lungs to deliver breaths to the patient. A laryngoscope is a device used for intubation.

[0004] Currently, conventional video laryngoscopes come in two form factors. In the first form factor, the display is detached from the handle and the display is attached to a cart. The display attached to the cart has limited maneuverability. In addition, the display is 7 inches to 11 inches in size, and the cart is bulky and difficult to move around. When performing an intubation procedure, the clinician needs 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 procedure failure. In addition, cart-based systems tend to be more expensive, and hospitals purchase some units for sharing in multiple operating rooms. This results in a video laryngoscope that is not available for every intubation procedure. 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 not manipulable. These two forms lead to increased risks for patients and lead to repeated intubations.

[0005] In addition, conventional video laryngoscopes include reusable blades that are used repeatedly for intubation procedures. Reusing blades can lead to higher infection risks, increased operational burdens on hospitals, and high cost of ownership.

[0006] Therefore, there is a need for a video laryngoscope that can overcome some or all of the disadvantages of the prior art. Summary of the invention

[0007] According to the present aspect of the invention, there is provided a video laryngoscope that can provide enhanced visualization during an intubation procedure. The video laryngoscope can include a handle for improved gripping, facilitating use during intubation. At the lower end of the handle, a camera housing can be arranged, which can include an image sensor and a light source. A deflector can be positioned between the image sensor and the light source to minimize light scattering and improve image quality during the procedure.

[0008] The video laryngoscope may also include a display unit that may be removably attached to the handle by a hinge mechanism, thereby enabling an adjustable viewing angle during use. The display unit may also be connected to the handle by an attachment assembly comprising a quick connect and release mechanism. The mechanism may be facilitated by radially biased spherical protrusions, thereby allowing secure attachment and easy removal. Furthermore, the display unit may be adapted to automatically adjust the orientation of the displayed image when rotated, thereby ensuring clear viewing from a variety of procedural positions.

[0009] In one embodiment, the deflector may be removable and the deflector may be replaceable, allowing for maintenance or replacement as needed. The display unit may also include a user accessible record button, enabling the clinician to capture images and video during the intubation procedure.

[0010] The attachment assembly of the display unit and the handle can integrate automatic electrical connection upon attachment. Specifically, once the display unit is aligned and attached to the handle, the electrical connector within the attachment assembly can automatically establish a connection. This feature allows for immediate visual feedback on the display screen. The display unit can also include an output port for connecting an external display for wider viewing access, particularly in a teaching environment or complex procedures.

[0011] In another aspect, a spherical protrusion within the attachment assembly may be mechanically biased to extend and retract, thereby ensuring secure attachment of the display unit while facilitating easy removal when necessary. To enhance sterility during the procedure, the laryngoscope may be equipped with a disposable cover that wraps around both the display unit and the attachment assembly, thereby maintaining a sterile environment throughout the intubation.

[0012] The handle of the video laryngoscope may also feature a double ball mechanism to enable a secure and quickly detachable connection for multiple blade types. The laryngoscope may support different blade geometries for adults and children, thereby enhancing the versatility of the laryngoscope in medical procedures.

[0013] The display unit may include a touch screen interface that enables interactive control of device settings, access to stored data, and adjustment of operating parameters. In addition, the display unit may have an automatic image orientation correction function that adjusts the displayed image to a standard upright orientation when the display is rotated approximately 180 degrees. This feature is particularly useful during procedures involving patients with elevated body mass index where different viewing angles are required.

[0014] In some embodiments, the image orientation correction feature can be enabled by user input (e.g., a sliding gesture on the display screen or pressing a designated button). The display unit can also have a rotation mechanism capable of 360-degree movement with predetermined stop positions at specific angles for optimal viewing. The automatic image orientation correction feature can ensure correct display alignment at each stop.

[0015] Additionally, the display unit may provide password protected access to the stored visual data, requiring a user defined password to access the saved video files or connect to an external computing device such as a personal computer, tablet or other similar device. The password protection feature may further enhance data security and protect patient information. The video laryngoscope may include a default password that may be user configurable to a six digit combination, thereby ensuring flexible but secure access to sensitive data.

[0016] The present invention may also provide encryption and password protection features to secure the connection of the video laryngoscope, thereby preventing unauthorized access or data transfer during or after the intubation procedure.

[0017] In one embodiment, the laryngoscope may include an integrated visual transmission capability through a camera channel. The camera assembly located within the channel may include a light source and an image sensor, which are separated by a light-absorbing deflector to reduce glare. The display unit may be attached to the handle by a hinge, which allows the display unit to be rotated and provide an optimal viewing angle. The connection system between the handle and the display unit may also include a housing with an electrical connector to enable instant visual feedback on the display.

[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 infection rates in hospitals.

[0020] It is yet another object of the present invention to provide a video laryngoscope suitable for capturing a clear and undistorted image of the path of an endotracheal tube, larynx, trachea, or airway.

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

[0033] Embodiments of the present invention that illustrate its features will now be described in detail. The words "include," "have," "contain," and "comprises," and other forms thereof, are intended to be synonymous and open ended, in that one or more items following any of these words are not intended to be an exhaustive list of the one or more items, nor are they intended to be limited to the one or more items listed.

[0034] The present invention provides a video laryngoscope. The video laryngoscope is adapted to seamlessly attach and detach a display unit and a blade to and from a handle. The video laryngoscope is adapted to avoid blurring and distorted visuals of the path of an endotracheal tube. Furthermore, the video laryngoscope is adapted to control infection rates that may be spread by conventional laryngoscopes. Furthermore, the video laryngoscope allows a clinician to perform an intubation procedure without sacrificing visibility of the display unit.

[0035] The terms "first", "second", etc. herein do not denote any order, quantity, or importance, but are used to distinguish one element from another, and the terms "one" and "an" herein do not denote a limitation of quantity, but rather denote the presence of at least one of the referenced items. The disclosed embodiments are merely examples of the invention that may be embodied in various forms.

[0036] Reference now Figure 1 , Figure 2a and Figure 2b , shows a video laryngoscope 100 according to the present invention. The video laryngoscope 100 includes a handle 10, a blade 20, a display unit 30, and an attachment assembly 25 for attaching the display unit 30 to the handle 10. The handle 10 is an elongated member having an ergonomic design that allows a clinician to easily hold the handle 10 during the intubation process. The handle 10 has an upper end and a lower end. The upper end of the handle 10 is provided with a receiving port 12 for receiving the attachment assembly 25.

[0037] The lower end of the handle 10 is provided with a tapered portion 14. Specifically, the lower end of the handle 10 is provided with a camera channel 15 extending from the tapered portion 14 of the handle 10. The camera channel 15 is a flexible link extending from the tapered portion 14 of the handle 10, and the camera channel 15 includes a circuit to transmit visual data (such as images and videos) to the receiving port 12. Specifically, the camera channel 15 is electrically connected to the first terminal 122 of the receiving port 12. The camera channel 15 has: a first end connected to the tapered portion 14 of the handle 10; and a second end including a camera kit 16. The camera kit 16 of the camera channel 15 is configured to capture visual data of the path of the endotracheal tube, larynx, trachea, or airway.

[0038] Reference now Figure 1 and Figure 3, the camera kit 16 includes an image sensor 161 and a light source 162. The image sensor 161 helps capture visual data of the path of the endotracheal tube, larynx, trachea or airway. Specifically, the image sensor opening 1611 in the camera kit 16 allows the image sensor 161 to capture visual data of the path of the endotracheal tube, larynx, trachea or airway. In the current aspect of the present invention, the image sensor 161 is a 2 megapixel (MP) camera, but those skilled in the art can use any other image sensor 161 with different specifications. For example, those skilled in the art can configure the image sensor to meet different specifications, such as a higher resolution sensor (e.g., 5MP or 10MP) for more detailed imaging. The image sensor can also include options for adjusting image brightness, contrast, and zoom functions to obtain better visual data of the intubation path.

[0039] In addition, the camera kit 16 includes a light source opening 1621 to allow the light source 162 to illuminate the path of the endotracheal tube and the airway. In addition, the camera kit 16 has a deflector 18. Specifically, the deflector 18 is arranged on the outer surface of the camera kit 16 and separates the image sensor opening 1611 from the light source opening 1621. The deflector 18 prevents the light source 162 from being directly exposed to the image sensor 161. The light source 162 is configured to provide focused illumination of the path of the endotracheal tube, the larynx, and the trachea. Depending on the clinical environment or the patient's anatomical structure, the light source can be configured to emit light of different intensities. In particular, the light source is adjustable to illuminate dark or blurred areas, thereby ensuring clear visibility during the intubation process.

[0040] In the present aspect of the invention, the deflector 18 is a rectangular strip, such as Figure 4 As shown. The rectangular strip is made of a silicone material. Those skilled in the art may configure the deflector 18 to have any other material, shape or size depending on the size and position of the image sensor 161 and the light source 162. The deflector 18 is horizontally arranged between the light source opening 1621 and the image sensor opening 1611 to avoid scattering of light on the image sensor 161. Specifically, the deflector 18 is positioned between the light source 162 and the image sensor 161 to minimize light scattering that may blur or distort the visual data captured by the image sensor 161. The deflector 18 is made of a silicone material that is known for its light absorbing properties, but other light absorbing materials (such as polycarbonate or specialty plastics) may also be used. This ensures that the captured image is clear and free of glare or halos that may obscure the clinician's field of view.

[0041] Reference now Figure 3 and Figure 4, the deflector 18 includes a rectangular portion 181 and two supporting portions 182a, 182b extending from the ends of the rectangular portion 181. The two supporting portions 182a, 182b are provided with corresponding locking elements 1821a, 1821b to attach the deflector 18 to the camera device kit 16. Specifically, the camera device kit 16 has two openings (not shown) to receive the locking elements 1821a, 1821b of the two supporting portions 182a, 182b to hold the deflector 18 on the outer surface of the camera device kit 16. The deflector 18 is attached to the camera device kit 16 in a fixed manner using the locking elements 1821a, 1821b, but those skilled in the art may provide the deflector 18 to be detachable from the camera device kit 16. Specifically, if the deflector 18 has been damaged or needs to be replaced, the deflector 18 may be detached from the camera device kit 16.

[0042] In another aspect of the present invention, the deflector 18 is a protrusion (not shown) extending from the outer surface of the camera assembly 16. The protrusion is disposed between the image sensor opening 1611 and the light source opening 1621 to avoid direct light exposure from the light source 162 to the image sensor 161. The scattering of light from the light source 162 distorts and blurs the image. The deflector 18 avoids direct exposure of the light source 162 to the image sensor 161 to avoid distortion and blurring of the image.

[0043] In another aspect of the present invention, the deflector 18 is a thin sheet disposed between the image sensor opening 1611 and the light source opening 1621. The sheet may be made of any material that absorbs light to avoid direct exposure of the light source 162 on the image sensor 161.

[0044] Reference now Figure 1 and Figure 5, a display unit 30 is provided, which can be attached to the handle 10 by an attachment assembly 25. The attachment assembly 25 includes a housing 27 and a second terminal 28 electrically connected to the display unit 30. The housing 27 is connected to the display unit 30 using a hinge 26. The hinge 26 is configured to pivot the display unit 30 in the front-to-back direction. The hinge 26 is connected to the display unit 30 and the housing 27. Specifically, the hinge 26 has a connecting element (not shown) suitable for attachment to the housing 27. The housing 27 receives the connecting element of the hinge 26 to allow the display unit 30 to rotate freely around the central axis of the handle 10. The hinge 26 allows the display unit 30 to rotate in all possible directions to configure the display unit 30 in a desired position, thereby providing better visibility for the clinician. The hinge 26 that connects the display unit 30 to the handle 10 allows 360-degree rotation, but it also includes predetermined stops at angles such as 45 degrees, 90 degrees, 180 degrees, and 270 degrees. These stops are built into the hinge mechanism, ensuring that the display unit locks into place at these angles. This helps the clinician maintain a stable and optimal view of the airway during intubation without the need for manual adjustments. Automatic image adjustment ensures that the image remains correctly oriented regardless of the rotation of the display unit.

[0045] In addition, the housing 27 includes two spherical protrusions 271a, 271b extending from the outer surface of the housing 27 and arranged opposite to each other to securely attach and detach the housing 27 to and from the handle 10. The two spherical protrusions 271a, 271b are offset to extend radially away from the central axis of the housing 27. The housing 271a, 271b is attached to the receiving port 12 of the handle 10. Specifically, the receiving port 12 has two openings 121a, 121b to receive the corresponding spherical protrusions 271a, 271b of the housing 27 to securely hold the housing 27 in the receiving port 12 of the handle 10. The two spherical protrusions 271a, 271b ensure that the housing 27 remains in place until the two spherical protrusions 271a, 271b are pressed to detach the housing 27 of the attachment assembly 25. Specifically, the two spherical protrusions 271a, 271b have corresponding balls arranged at the extreme ends so that the two spherical protrusions 271a, 271b are easily pressed when the housing 27 is removed from the handle 10. The two spherical protrusions 271a, 271b are located on opposite sides of the housing 27. These spherical protrusions are mechanically biased to extend radially outward from the housing 27 and engage with corresponding sockets in the receiving port 12 of the handle 10. This engagement ensures a secure attachment, while pressing the spherical protrusions inward allows for quick removal of the display unit 30. The spherical protrusions are designed to operate with minimal force, allowing the clinician to quickly adjust or remove the display unit during the intubation procedure.

[0046] Once the display unit 30 is attached to the handle 10 via the attachment assembly 25, the second terminal 28 of the attachment assembly 25 is electrically connected to the first terminal 122 of the receiving port 12 of the handle 10 to establish an electrical connection between the camera channel 15 and the display unit 30. Specifically, after the attachment assembly 25 is attached to the handle 10, the first terminal 122 and the second terminal 28 immediately establish an electrical connection between the image sensor 161 and the display unit 30, thereby enabling instant display of visual information of the path of the endotracheal tube, larynx, trachea or airway on the display screen 34.

[0047] In addition, the attachment assembly 25 includes a record button 29 (eg, Figure 5 ) for capturing images or recording videos. In the current aspect of the present invention, the record button 29 is disposed on a portion of the housing 27. However, those skilled in the art may dispose the record button 29 on any other portion so that the clinician's thumb can easily reach the record button 29 to capture images or record videos. The display unit 30 also includes an automatic image orientation correction feature 30a, such as Figure 7a to Figure 7b As the display unit 30 is rotated downward or upward approximately 180 degrees or other angles, the image on the display screen 34 automatically adjusts to ensure proper alignment for the clinician. This is particularly beneficial for procedures involving high BMI patients, where the rotated display screen ensures better visibility and access to the airway.

[0048] Reference now Figure 1 , Figure 3 and Figure 5 The display unit 30 includes a battery (not shown), a power button 32, an output port 33, a display screen 34, a touch user interface (TUI) (not shown), a processor (not shown), and a memory (not shown) for storing visual data of the path of the endotracheal tube, larynx, trachea or airway. The battery is arranged in the display unit 30 to supply power to the display screen 34, the image sensor 161 and the light source 162. The battery can be a replaceable battery or a rechargeable battery.

[0049] In another aspect of the invention, the handle 10 includes a battery (not shown) that can be used to supply power to the image sensor 161 and the light sensor 162 when the display unit 30 is not attached to the handle 10. In this case, the handle 10 establishes a wireless connection with the display unit 30 or an external display (not shown) to transmit visual data of the path of the endotracheal tube, larynx, trachea, or airway from the image sensor 161 to the display unit 30 or external display.

[0050] The power button 32 is arranged on either side of the side of the display unit 30. The power button 32 is within the range of the clinician's finger. In the current aspect of the present invention, the power button 32 is arranged at the lower left of the display unit 30. The power button 32 is used to power on or off the display screen 34. Specifically, press and release the power button 32 to power on the display screen 34, and press and hold the power button 32 for 3 seconds to 4 seconds to power off the display screen 34. Those skilled in the art can configure the duration for holding the power button 32 to power off the display screen 34. In the current aspect, the power button 32 is located at the lower left of the display unit 30. A short press enables the display screen 34, the image sensor 161 and the light source 162, while a long press (3 seconds to 4 seconds) turns off the unit. This minimizes accidental shutdowns and ensures that the display is functioning properly when needed. The record button 29 on the housing also allows the clinician to capture visual data during the procedure, so that the captured data is automatically saved in a safe, password-protected folder.

[0051] In another aspect of the invention, once the display unit 30 is attached to the handle 10 and the display screen 34 is powered on using the power button 32, the display screen 34 begins to display visuals of the path of the endotracheal tube. The display screen 34 automatically begins to display visuals of the endotracheal tube without pressing the record button 29.

[0052] In another aspect of the present invention, the video laryngoscope 100 is adapted to start displaying visual data on the display screen 34 even if the display unit 30 is not attached to the handle 10. The display screen 34 displays the visual data by establishing a wireless connection between the handle 10 and the display unit 30.

[0053] In addition, output ports 33 are provided on either side of the side of the display unit 30 for connecting the display unit 30 to an external display (not shown) to display visual information of the path of the endotracheal tube. The external display has a larger screen size than the display screen 34 of the display unit 30. It is obvious to those skilled in the art that multiple output ports are provided on the display unit 30.

[0054] The display screen 34 of the display unit 30 is adapted to display visual data of the path of the endotracheal tube received from the image sensor 161. In the current aspect of the invention, the display unit 30 has a rectangular shape to accommodate the display screen 34. The display screen 34 has a size of 3.5 inches to provide better visibility from all angles. It is obvious to those skilled in the art that the size of the display screen 34 can be increased as needed.

[0055] In addition, a touch user interface is provided to allow the clinician to interact with the video laryngoscope 100. The touch user interface of the display 34 is suitable for viewing and managing previously recorded images or videos stored in the memory of the display unit 30. The touch user interface includes a home page for displaying the current time and date, a menu icon for accessing multiple icons, and a battery icon for indicating the battery level. The display 34 is powered on using the power button 32 to display the home page. In the present aspect, the touch user interface (TUI) of the display 34 allows the clinician to manually enable functions such as Figure 7a and Figure 7b The image orientation correction feature 30a is shown. The image orientation can be flipped by swiping up on the display screen 34 or by pressing a dedicated "flip" button on the display unit 30. The clinician interacts with the menu icon of the home page by touching the menu icon displayed on the display screen 34 to access multiple icons. The menu icon is set in the lower left corner of the display screen 34 to allow the clinician to reach the menu icon with one hand. After touching the menu icon, the processor receives the touch input from the touch user interface and processes the command to display multiple icons on the display screen 34.

[0056] In addition, the video laryngoscope 100 includes a storage device for storing visual data (e.g., Figure 8a and Figure 8b The display unit 30 also includes a security mechanism 30b for accessing the data stored on the display unit 30, such as images and video captured during the intubation procedure. Access to data stored on the display unit 30 requires a password, which can be defined by the user. The default password is "000000," but the clinician can configure it to any six-digit combination to enhance patient data security. The touch screen interface on the display unit 30 provides intuitive navigation of the device's settings and stored data. Clinicians can interact with the touch user interface (TUI) using simple gestures (such as swiping or tapping icons) to adjust brightness, access stored images, or enable image orientation correction features. The display screen 34 is also designed to remain responsive even when the clinician is wearing medical gloves, ensuring seamless operation. The display unit 30 also includes security mechanisms 30b for protecting data during transmission to an external device (e.g., a PC, tablet, or other computing resource), such as an encryption system, such as Figure 8a and Figure 8b As shown in Figure 1. A password is required not only to access the stored data, but also to connect the video laryngoscope to external computing resources, ensuring that sensitive medical data remains secure. The encryption extends to data transmission, ensuring that files sent to external devices such as PCs or tablets are protected by encryption protocols such as AES-256. This level of encryption ensures compliance with healthcare data security standards.

[0057] A plurality of icons are assigned with specific actions to be performed upon receiving a command from the processor of the display unit 30. Specifically, the plurality of icons include a setting icon for changing the brightness of the display screen, the volume of the sound, opening or closing the output port 33, etc. In addition, the plurality of icons include a photo icon for viewing and managing previously recorded images and a video icon for viewing and managing previously recorded videos. In another aspect of the present invention, the plurality of icons include a folder icon for viewing and managing previously recorded images and videos in one place. Those skilled in the art may add more icons to the plurality of icons to provide additional features and functions.

[0058] When the clinician presses the record button 29 to capture an image, the touch user interface is adapted to display an indication of the captured image on the display screen 34. Additionally, when the record button 29 is pressed and held to record a video, the touch user interface is adapted to display a timer for the recording on the display screen 34. Additionally, the timer disappears from the display screen 34 after the record button 29 is pressed to stop recording.

[0059] In another aspect of the present invention, the display unit 30 includes a charging lamp 35 for indicating the charging state of the battery. When the battery is connected to a power source to charge the battery, the charging lamp 35 is lit, and when the battery is not connected to a power source to charge, the charging lamp 35 is off. It is obvious to those skilled in the art that the charging lamp 35 is arranged in any corner of the display unit 30.

[0060] Reference now Figure 1 , Figure 5 and Figure 6 , a display cover 40 is provided to prevent the display unit 30 and the attachment assembly 25 from being infected during the intubation process. The display cover 40 is made of a transparent material to allow the clinician to view the display screen 34 without any obstruction. The display cover 40 includes a lower panel 42 and an upper panel 44 hinged at a hinge point. The lower panel 42 and the upper panel 44 pivot about the hinge point to cover the display unit 30. After the display unit 30 is placed in the cavity of the display cover 40, the upper panel 44 and the lower panel 42 of the display cover 40 are pressed to snap fit with each other. In addition, the upper panel 44 has a flexible sheath (not shown) that extends from the free end of the upper panel 44 to cover a portion of the handle 10 and the attachment assembly 25. The display cover 40 is disposable and can be discarded once the intubation process is completed.

[0061] Reference again Figure 12 , the handle 10 is adapted to receive a blade 20 from the lower end of the handle 10. The blade 20 is received around the outer surface of the handle 10 to completely cover the handle 10 and the camera channel 15. The blade 20 is attached to the handle 10 when the intubation process is performed. The handle is adapted to receive all types of blades, such as Macintosh and Miller. In addition, the handle 10 is adapted to receive adult blades and pediatric blades. The camera channel 15 is adapted to receive all types of blades for both adults and children, such as Macintosh and Miller. The handle 10 does not require any other adjustment or installation to receive adult blades and pediatric blades. The blade 20 can be slid on the camera channel 15 to attach to the handle 10 to perform the intubation process. The blade 20 is detachably attached to the handle 10 and can be detached from the handle 10 after the intubation process.

[0062] In the present aspect of the invention, the blade 20 can be attached to the handle 10 by the attachment mechanism 21 of the handle 10. The attachment mechanism 21 includes two spherical protrusions 211a, 211b, which are arranged opposite to each other to firmly attach and detach the blade 20 to the handle 10. The two spherical protrusions 211a, 211b are biased to extend radially away from the central axis of the handle 10. The two spherical protrusions 211a, 211b engage with the blade 20. Specifically, the blade 20 has two openings (not shown) to engage with the two spherical protrusions 211a, 211b of the handle 10, thereby firmly holding the blade 20 on the handle 10. The two spherical protrusions 211a, 211b ensure that the blade 20 remains in place until the two spherical protrusions 211a, 211b are pressed to detach the blade 20. The blade 20 is disposed of after being removed from the handle 10 to reduce the chance of infection and cross contamination. Disposal of the blade 20 after a single use allows the video laryngoscope 100 to control the spread of infection that may be spread by repeated use of the same blade.

[0063] In addition, blade 20 has a camera assembly opening 165 to allow image sensor 161 and light source 162 to capture visual data of the path of the endotracheal tube. Image sensor 161 captures visual data of the path of the endotracheal tube, larynx, trachea or airway and transmits the visual data to display unit 30.

[0064] Before performing the intubation process, the clinician attaches the blade 20 to the handle 10. The blade 20 can be an adult blade or a pediatric blade. The blade 20 can slide on the camera channel 15, and the blade 20 is attached to the handle 10 by the attachment mechanism 21 of the handle 10.

[0065] Reference now Figures 9a to 9cIn the current embodiment of the present invention, the blade 20 can be attached to the handle 10 by the attachment mechanism 21 of the handle 10. The attachment mechanism 21 includes at least two spherical protrusions 211a, 211b, which are arranged opposite to each other to firmly attach and detach the blade 20 to the handle 10. The two spherical protrusions 211a, 211b are biased to extend radially away from the central axis of the handle 10. The two spherical protrusions 211a, 211b are configured to engage with the blade 20. Specifically, the two spherical protrusions 211a, 211b are biased to extend radially outward from the center of the handle 10 using a biasing member 212 (e.g., a spring member). The biasing member 212 is positioned inside the handle 10 and applies a continuous force to the spherical protrusions 211a, 211b to configure the extended position of the two spherical protrusions 211a, 211b during the attachment of the blade 20. The two spherical protrusions 211a, 211b have corresponding biasing members 212a, 212b to bias the two spherical protrusions 211a, 211b away from the handle 10 to engage the blade 20 and hold the blade 20 in the attached position. When the blade 20 is attached, the spherical protrusions 211a, 211b engage with the corresponding 122 223a, 223b in the blade 20, thereby holding the blade 20 around the handle 10.

[0066] Reference now Fig.10 , the blade 20 includes an attachment portion 251, a grip portion 252, and a tongue portion 253. The attachment portion 251 is located at the proximal end of the blade 20, and the attachment portion 251 is suitable for attaching the blade 20 to the handle 10. The attachment portion 251 includes at least two openings 223a, 223b positioned to engage with the two spherical protrusions 211a, 211b of the handle 10. The two openings 223a, 223b are configured to engage with the corresponding two spherical protrusions 211a, 211b during the intubation process. The attachment mechanism 21 allows the handle 10 to be removed by pressing the two spherical protrusions 211a, 211b inwardly. The blade 20 has a first cavity 256 formed at the attachment portion 251 and the grip portion 252 of the blade 20. The first cavity 256 has a shape suitable for fitting on the handle 10 and covering the handle 10 during the intubation process. The first cavity 256 allows the blade 20 to receive the handle 10 and hold the handle 10 securely in place during the intubation process. The first cavity 256 is formed at the attachment portion 251 and extends through the grip portion 252.

[0067] The grip portion 252 is a middle section of the blade, and the grip portion 252 is arranged between the grip portion 251 and the tongue portion 253. The grip portion 252 is configured to provide a grip for the clinician during the intubation process. The grip portion 252 has indentations (not shown) or other surface textures on the outer surface of the grip portion 252 to enhance the clinician's grip.

[0068] In addition, the tongue portion 253 is the distal end of the blade 20 located behind the grip portion 252. The tongue portion 253 is configured to interact with the patient's body structure, particularly during intubation. In the present embodiment, the tongue portion 253 is an integral part of the blade 20 and extends laterally from the grip portion 252. The tongue portion 253 is configured to receive the camera channel 15 and the camera kit 16. The tongue portion 253 includes a camera kit opening 165 to accommodate the camera kit 16, which faces the outside of the blade 20, thereby allowing the image sensor 161 disposed within the camera kit 16 to capture visual data of the patient's airway (including the endotracheal tube, larynx and trachea).

[0069] Specifically, the blade 20 has a second cavity 257 formed at the tongue portion 253 of the blade 20. The second cavity 257 is configured to accommodate the camera channel 15 and the camera kit 16 therein. The second cavity 257 accommodates the camera channel 15 extending along the length of the tongue portion 253. The second cavity 257 provides space for the camera channel 15 to be accommodated within the blade 20. In addition, the camera kit 16 is exposed through the camera kit opening 165 arranged in the tongue portion 253 to allow the image sensor 161 to capture visual data of the patient's airway.

[0070] After the cannulation process, the blade 20 can be removed from the handle 10 by pressing the two spherical protrusions 211a, 211b against the biasing force applied by the biasing members 212a, 212b. When pressure is applied to the two spherical protrusions 211a, 211b, the two spherical protrusions 211a, 211b are pushed inward, thereby overcoming the biasing force of the biasing members 212a, 212b and moving toward the center of the handle 10 (e.g., Figure 9b The two spherical protrusions 211a, 211b move toward the center of the handle 10 to disengage the corresponding openings 211a, 211b in the blade 20, thereby allowing the blade 20 to be removed from the handle 10. In particular, after pressing the two spherical protrusions 211a, 211b, the blade 20 can slide on the handle 10 and the camera channel 15 in a downward direction (as shown in FIG. Fig.9c ), thereby completely removing the blade 20 from the handle 10 and discarding the blade 20 after the intubation process.

[0071] In addition, the display unit 30 is placed inside the lower panel 42 of the display cover 40, and the upper panel 44 pivots to close the display cover 40. The flexible sheath is wrapped around the portion of the handle 10 and the attachment assembly 25. Once the flexible sheath is wrapped, the video laryngoscope 100 is ready for the intubation process. The display unit 30 rotates to configure the position according to the clinician's requirements. The hinge 26 facilitates the movement of the display unit 30.

[0072] While performing the intubation process, the power button 32 is pressed to enable the display screen 34, the image sensor 161, and the light source 162. Visual data of the path of the endotracheal tube and the airway are displayed on the display screen 34. The deflector 18 of the camera assembly 16 reduces the scattering of light from the light source 162. The deflector 18 helps reduce the distortion and blur of the image. In addition, a record button 29 is provided for capturing images and recording videos. Press and release the record button 29 to capture images, and press and hold the record button 29 for 2 seconds to 3 seconds to record videos. The video laryngoscope 100 is completely covered from the outside, thereby eliminating the risk of infection of the video laryngoscope 100. After the intubation process, the display cover 40 is removed from the display unit 30 and discarded to avoid spreading infection. In addition, the blade 20 is removed from the handle 10. The blade 20, which mainly contacts the body part, is discarded after one use, which helps reduce the infection rate or cross-contamination transmission rate caused by the reuse of the blade 20.

[0073] In addition, the video laryngoscope 100 allows the clinician to free one hand while operating the video laryngoscope 100 during the intubation process. In the operating room, the clinician needs to free his hands to use multiple devices or perform multiple actions at the same time. By placing the power button 32 at the lower left of the display unit 30, placing the menu icon 34 at the lower left of the display screen, and placing the record button 29 below the display unit 30, the clinician can fully operate the video laryngoscope 100 with his left hand, thereby freeing up his right hand.

[0074] In another aspect of the present invention, a video laryngoscope 100 includes a handle 10, a blade 20, and a display unit 30. The display unit 30 is attached to the handle 10 without using an attachment assembly 25. Specifically, the display unit 30 includes an attachment element (not shown) extending from a bottom portion of the display unit 30 to attach to the handle 10. It is obvious to those skilled in the art that the attachment element of the display unit 30 is configured to provide a threaded attachment or a snap-fit ​​attachment or the like to ensure a secure and functional connection between the display unit 30 and the handle 10.

[0075] 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 adapted to receive an adult blade as well as a pediatric blade, which reduces other requirements such as using different handles for different blades or mountings on the same handle 10 for receiving different types of blades. In addition, the deflector 18 reduces distortion and blurring of the image to obtain better quality visualization. In addition, the blade 20 covers the handle 10, and the display cover 40 covers the display unit 30, which completely covers the video laryngoscope 100 and prevents the video laryngoscope 100 from infection during the intubation procedure.
