Description

Technical Field

[0001] This application relates to the field of medical device technology, and in particular to a video laryngoscope. Background Technology

[0002] Video laryngoscopes are an important tool for endotracheal intubation in clinical anesthesia and emergency care. By setting a miniature camera and light source at the end of the laryngeal blade, they transmit real-time images of the patient's oral cavity and pharynx (especially the glottic region) to a display screen for the operator to observe, thereby significantly improving the success rate of intubation and reducing damage to the patient.

[0003] Currently, most video laryngoscopes widely used in clinical practice are one-piece designs, meaning the display screen is fixedly mounted on the top or back of the laryngoscope handle, forming an inseparable unit together with the handle and laryngoscope blades. This type of one-piece video laryngoscope has the following significant drawbacks:

[0004] Limited operating space: The integrated design of the display screen and handle means that the laryngoscope occupies a large three-dimensional space in front of the patient's mouth. When the operator holds the handle with their left hand and inserts the laryngoscope blade into the patient's mouth to expose the glottis, the display screen fixed to the handle moves synchronously with the handle. Often, due to the patient's position (such as lying on their side, cervical spine immobilization), the operator's body shape, and the limitations of surrounding equipment (ventilator tubing, monitors, etc.), the display screen is not at an ideal viewing angle for the operator. The operator needs to twist their neck or body to see the screen clearly, which seriously affects the stability and safety of the intubation operation.

[0005] Inconvenient for multi-person collaboration: The display screen in the integrated structure can only be barely viewed by the operator holding the laryngoscope. The assistant assisting with intubation and the senior anesthesiologist cannot simultaneously and clearly view the pharyngeal image, which is not conducive to teaching guidance and emergency coordination.

[0006] Unreasonable center of gravity: In the integrated structure, the display screen, motherboard and battery are all concentrated at the top of the handle, which makes the laryngoscope's center of gravity too high. In special situations, airway patients are prone to fatigue during long-term operation, and the shift in the center of gravity during the placement of the laryngoscope affects the fine control of the laryngoscope blade angle.

[0007] Disinfection and maintenance are inconvenient: The integrated structure makes the whole machine large and irregular in shape, making it difficult to fit into a conventional disinfection tray; the display screen and electronic components cannot be separated, increasing the risk of liquid seepage and damage, which does not meet the infection control requirements of some departments for the separate management of display and operation units. Summary of the Invention

Detailed Implementation

[0041] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. Through these descriptions, the features and advantages of the present application will become clearer and more apparent.

[0042] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments. Although various aspects of embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless specifically indicated otherwise.

[0043] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0044] To facilitate understanding of the video laryngoscope provided in this application embodiment, its application scenario will be explained first. The video laryngoscope provided in this application embodiment is used to eliminate the encroachment of the display screen on the operating space of the handle, allowing the operator to freely position the display screen at the optimal viewing angle according to their own standing position, while facilitating simultaneous observation and learning by assistants or colleagues. Currently, most video laryngoscopes widely used in clinical practice are of an integrated structure, that is, the display screen is fixedly installed on the top or back of the laryngoscope handle, forming an inseparable whole with the handle and laryngoscope blade. This type of integrated video laryngoscope has the following significant drawbacks: Limited operating space: The integrated design of the display screen and handle makes the laryngoscope occupy a large three-dimensional space in front of the patient's oral cavity. When the operator holds the handle with their left hand and inserts the laryngoscope blade into the patient's oral cavity to expose the glottis, the display screen fixed on the handle moves synchronously with the handle. Often, due to the limitations of the patient's position (such as supine or lateral, cervical spine immobilization), the operator's body shape, and surrounding equipment (ventilator tubing, monitors, etc.), the display screen is in the operator's blind spot or has a very poor viewing angle. The operator needs to twist their neck or body to see the screen clearly, which seriously affects the stability and safety of intubation. Inconvenient for multi-person collaboration: The integrated structure of the laryngoscope results in several drawbacks. The display screen is only barely visible to the operator holding the laryngoscope, while assistants assisting with intubation and senior anesthesiologists cannot simultaneously view the throat image clearly, hindering teaching guidance and emergency coordination. Unreasonable center of gravity: The integrated structure concentrates the display screen, motherboard, and battery at the top of the handle, leading to a high center of gravity. This can cause fatigue during prolonged operation and affects the fine control of the laryngoscope blade angle during placement. Inconvenient disinfection and maintenance: The integrated structure results in a large, irregularly shaped device that is difficult to place in a standard disinfection tray. The inability to separate the display screen from electronic components increases the risk of liquid ingress and damage, failing to meet the infection control requirements of some departments that require separate management of the display and operating units. Therefore, this application provides a video laryngoscope that eliminates the encroachment of the display screen on the handle's operating space, allowing the operator to freely position the display screen at the optimal viewing angle based on their position, while facilitating simultaneous observation by the assistant. The following detailed description, in conjunction with specific accompanying drawings, illustrates the embodiments.

[0045] refer to Figures 1 to 9 This application provides a video laryngoscope, comprising: a separately configured display 1, a handle 2, and a laryngoscope blade 3, wherein...

[0046] The handle is detachably connected to the laryngeal blade.

[0047] The handle is wirelessly connected to the display. Specifically, the wireless connection can be any one of Wi-Fi, infrared, or 4G / 5G / 6G.

[0048] In the above technical solution, by setting up a separate display, handle and laryngeal blade, the handle and the laryngeal blade are detachably connected; the handle and the display are wirelessly connected; the display screen is eliminated from encroaching on the handle's operating space, allowing the operator to freely place the display screen at the best viewing angle according to their own position, while facilitating simultaneous observation and learning by assistants or colleagues.

[0049] Specifically, the beneficial effects include:

[0050] 1. Free up operating space and improve the flexibility of cannulation operations.

[0051] Traditional video laryngoscopes often integrate the display screen into the upper part of the handle, which can easily occupy the operating space in the oropharynx, limit the angle of handle movement, and increase the risk of tooth injury. This design separates the display screen from the handle, completely eliminating the encroachment of the display screen on the handle's operating space. Medical staff can freely adjust the handle's grip angle, expand the range of operation, reduce the probability of damage to the patient's teeth, oral cavity, and pharynx, and improve the convenience and safety of endotracheal intubation.

[0052] 2. Freely adjustable display angle to adapt to diverse clinical scenarios.

[0053] The monitor and handle are wirelessly connected, eliminating the limitations of cables and structural placement. Operators can position the monitor to the optimal viewing angle based on their height, standing habits, and the actual situation such as the position of the operating table and the patient's position, allowing for clear viewing of the laryngeal image without having to force themselves to bend over or twist their body, thus ensuring operational stability.

[0054] 3. Facilitates multi-person collaboration and improves emergency response efficiency.

[0055] The split design allows the assistant to simultaneously receive the display screen within the same space, facilitating real-time observation of the patient's throat condition and enabling them to assist the operator in performing auxiliary procedures such as suctioning, medication administration, and monitoring vital signs. Especially in time-sensitive scenarios such as emergency resuscitation, it enables seamless coordination between the operator and assistant, reducing intubation time and improving the success rate of emergency care.

[0056] 4. Modular design facilitates cleaning, maintenance, and functional expansion.

[0057] The laryngeal blade and handle are detachably connected, which meets the requirements of hospital infection control. It does not require disinfection or sterilization after single use and can be disposed of after use. At the same time, the modular structure makes it easy to replace damaged parts individually in the future, reducing equipment maintenance costs. Different sizes of laryngeal blades can also be flexibly replaced according to different patient groups to meet the intubation needs of different groups such as adults and children.

[0058] refer to Figure 3 and Figure 6 In one specific implementation, the laryngeal blade is a disposable core-type moldable laryngeal blade.

[0059] Specifically, the beneficial effects include:

[0060] Adapting to complex airway anatomy and improving intubation success rates: The moldable laryngeal blade with a stylet can be pre-bent to match the anatomical curve of the pharynx and larynx according to individual patient airway differences (such as micrognathia, limited cervical spine mobility, and other difficult airways). This allows the laryngeal blade to better fit the patient's posterior pharyngeal wall, providing a clearer field of vision when exposing the glottis and effectively addressing various difficult airway challenges.

[0061] Combining support and shaping for an optimized user experience: This laryngeal blade combines the support of the stylet with its malleability. It maintains a certain rigidity after shaping to ensure that the endotracheal tube does not easily deform during advancement, guiding the tube smoothly into the glottis. At the same time, it allows the operator to adjust the shape at any time according to clinical needs, balancing operational flexibility and insertion stability.

[0062] Reduced risk of tissue damage: Due to its excellent fit, it significantly reduces the risk of damage to the patient's teeth, gums, and pharyngeal mucosa, improving the safety of clinical use.

[0063] In one specific implementation, the disposable core-type malleable laryngeal blade includes a connecting housing and a tube body 34, wherein the tube body is malleable.

[0064] The connecting housing is detachably connected to the handle;

[0065] One end of the malleable tube is connected to the connecting housing, and the other end of the malleable tube is provided with a camera assembly 36.

[0066] Specifically, the beneficial effects include:

[0067] Optimized structural layout ensures stable signal transmission: The connecting housing is used as the core component for docking the laryngeal lens with the handle. This not only enables quick assembly and disassembly and secure locking of the two, but also provides a neat transition space for the internal circuitry. This ensures that the image data collected by the camera component can be stably and efficiently transmitted to the handle and the display, avoiding signal interruption or poor contact caused by loose connections.

[0068] Leveraging its malleability for precise airway adaptation: The malleable tube body grants operators a high degree of freedom, allowing them to adjust the tube's curvature before or during the procedure according to the patient's specific airway anatomy (such as curvature and location of narrowing). This personalized shaping capability enables the laryngoscope blade to closely conform to the patient's natural pharyngeal curve, minimizing mechanical damage to the pharyngeal tissues while precisely exposing the glottis, significantly improving the success rate and safety of endotracheal intubation.

[0069] Modular design facilitates maintenance and cost control: the connecting shell and the malleable tube can be manufactured independently using different materials and processes, reducing the overall manufacturing difficulty. Furthermore, if the tube is damaged due to repeated shaping or sterilization, only the tube itself can be replaced, eliminating the need to discard the entire laryngoscope blade. This effectively saves on clinical consumable costs and extends the equipment's lifespan and economic efficiency.

[0070] In one specific implementation scheme, a connecting plate 31 is provided inside the connecting housing, wherein...

[0071] The connecting plate is electrically connected to the camera assembly.

[0072] The connecting plate is electrically connected to the handle.

[0073] Specifically, the beneficial effects include:

[0074] Ensuring stable and reliable electrical connections: The connector plate, acting as a central hub between the camera assembly and the handle, provides a standardized hard-wired interface. Compared to traditional flying wires or flexible connectors, the connector plate effectively resists vibration and pulling during the installation, removal, and use of the laryngeal blade, preventing signal transmission interruptions caused by loose or detached wires and ensuring continuous and stable image signal transmission.

[0075] Simplified assembly and maintenance: This structure integrates complex internal wiring onto a single connecting board, enabling modular assembly. During production, the camera components can be pre-soldered to the connecting board; during installation, simply align the connecting board with the handle interface to complete the connection, significantly improving assembly efficiency. Furthermore, if a circuit malfunctions, the connecting board module can be directly replaced, reducing troubleshooting difficulty and maintenance costs.

[0076] Improved structural compactness and durability: The connecting plate cleverly utilizes the limited space inside the connecting housing to make the wiring more orderly and organized, avoiding wire tangling or pressure, and enhancing the overall structural strength and service life of the laryngoscope blade.

[0077] In one specific implementation, the connecting housing includes an upper shell 32 and a lower shell 33, wherein,

[0078] The upper shell and the lower shell are detachably connected.

[0079] Specifically, the beneficial effects include:

[0080] Greatly facilitates the assembly and maintenance of internal components: The detachable design of the upper and lower shells allows the interior of the connecting housing to be completely open, enabling operators to easily and accurately lay out and fix the connecting board, camera component cables, and other electronic components in predetermined positions, effectively reducing assembly difficulty and improving production efficiency. When internal circuits or components malfunction, repairs can be quickly performed without damaging the housing, significantly reducing maintenance costs.

[0081] Enhanced sealing and protection: After the upper and lower shells are fastened together, a sealing ring can be set at the joint surface or ultrasonic welding can be used to form a closed internal space, which effectively prevents disinfectant, body fluid or water vapor from entering, protects the internal circuit board and precision contacts from corrosion, and extends the service life of the laryngeal blade.

[0082] Optimized manufacturing and cost control: The modular shell can be molded separately using injection molding, reducing the difficulty of mold development and the manufacturing defect rate for complex structural components. Furthermore, if a portion of the shell is damaged, only the corresponding upper or lower shell needs to be replaced, eliminating the need to scrap the entire component and further saving on clinical usage costs.

[0083] refer to Figure 5 and Figure 8 In one specific implementation scheme, the laryngeal blade is a disposable tube-type laryngeal blade 4, wherein,

[0084] The end of the disposable tube-type laryngeal blade is provided with a high-lens plate 44 for mounting the camera assembly.

[0085] The disposable tube-type laryngeal blade is fitted together with the malleable tube body;

[0086] The disposable tube-type laryngeal blade is provided with a high-lens plate 44 at the end corresponding to the camera component.

[0087] Specifically, the beneficial effects include:

[0088] To prevent cross-infection and meet high standards for hospital infection control: The disposable tube sleeve completely and physically isolates the malleable tube body from the patient's airway, preventing direct contamination of the laryngoscope blade by bodily fluids and blood. Only the tube sleeve needs to be replaced after each use, ensuring aseptic operation and fundamentally blocking cross-infection pathways between different patients, perfectly meeting the stringent standards of clinical hospital infection control.

[0089] Significantly reduced operating costs and turnover pressure: Because the tube sleeve is a disposable consumable, the expensive laryngeal blade body (including the camera component and tube body) only requires routine surface disinfection and can be reused, without undergoing complex processing procedures such as high-temperature and high-pressure sterilization that could damage delicate electronic components. This greatly extends the service life of core equipment, reduces the hospital's equipment procurement and maintenance costs, while also reducing disinfection waiting time and improving the instrument turnover efficiency of the operating room.

[0090] Ensuring high-quality optical imaging: The high-lens plate integrated at the end of the sleeve has excellent optical transmittance, effectively preventing fogging and moisture interference, ensuring clear and distortion-free images captured by the camera assembly. Compared to traditional methods of wrapping with cling film or ordinary plastic sleeves, this specialized design avoids the problem of lens wrinkles or stains obstructing the view, ensuring unobstructed vision and providing stable and reliable visual support for the operator.

[0091] Optimized operation feel and insertion smoothness: The inner wall of the special cannula fits tightly against the tube body, and the outer wall is usually treated with a low coefficient of friction, so that the cannula and the tube body are tightly connected and the shape is smooth. It is not easy to wrinkle or shift during insertion and removal, which protects the patient's mucosa and maintains the original shaping angle and maneuverability of the tube body.

[0092] refer to Figure 4 and Figure 7 In one specific implementation, the laryngeal blade is a core-type flexible laryngeal blade.

[0093] Specifically, the beneficial effects include:

[0094] Ultimately conforming to airway anatomy, overcoming the challenges of difficult airways: The flexible laryngeal blade with a stylet is made of a special flexible material, possessing excellent conformability and deformation capability. During insertion, its tube passively conforms to the natural physiological curvature of the patient's pharynx, automatically adjusting its trajectory and effectively avoiding tissue damage caused by the forced prying of a rigid laryngeal blade. This is especially important for patients with difficult airway characteristics such as micrognathia, cervical spondylosis, and obesity, significantly improving the intubation success rate.

[0095] Leveraging visualization capabilities, this solution enables "insertion only upon sight": Unlike traditional blind insertion with flexible tubing, this solution integrates a camera component at the front end of the flexible tubing. Guided by a monitor, the operator can observe and control the tubing tip as it passes through the glottis in real time, transforming "blind insertion" into "visible insertion." This visualized guidance significantly reduces operational difficulty and reliance on operator experience, while also avoiding the risk of the tubing accidentally entering the esophagus or damaging the tracheal wall.

[0096] Reduced tissue damage and stress response: The flexible tubing body is resilient and, when inserted into the endotracheal tube, produces a certain degree of cushioning deformation upon contact with the teeth, epiglottis, or vocal cords, significantly reducing the probability of mechanical stimulation and damage to the patient's oral soft tissues, teeth, and laryngeal structures. This not only improves the safety of the procedure but also reduces the patient's intubation stress response, making it particularly suitable for elderly patients or high-risk patients with cardiovascular disease.

[0097] Expanding clinical application scenarios: This flexible design is not only suitable for routine endotracheal intubation, but can also easily enter complex airways that are narrow, tortuous, or contain tumors, providing a wider range of reliable tool options for clinical anesthesia, emergency resuscitation, and intensive care.

[0098] In one specific implementation scheme, the core-type flexible laryngeal blade includes a connecting housing and a tube body 34, wherein the tube body is a flexible tube body.

[0099] The connecting housing is detachably connected to the handle;

[0100] One end of the flexible tube is connected to the connecting housing, and the other end of the flexible tube is provided with a camera assembly 36.

[0101] Specifically, the beneficial effects include:

[0102] Achieving precise and flexible intubation, enhancing the ability to manage difficult airways: The flexible tube conforms to the natural curvature of the patient's airway and automatically adjusts its shape during insertion, reducing the risk of tissue damage. Combined with real-time image guidance from the front-end camera component, the operator can clearly observe the path on the monitor and precisely control the tube to pass through the glottis, transforming traditional "blind intubation" into a visual operation, significantly improving the success rate of intubation, especially suitable for difficult airway scenarios such as micrognathia and limited cervical spine mobility.

[0103] Modular structure for easy disassembly and maintenance: The connecting housing, as an independent component, provides a quick and secure mechanical and electrical connection with the handle, ensuring reliable signal transmission. Simultaneously, the modular design allows the flexible tube body and connecting housing to be manufactured and replaced independently. When the tube body ages or is damaged due to repeated use, only the tube body needs to be replaced, eliminating the need for complete disposal and effectively reducing operating costs.

[0104] Balancing operational flexibility and imaging stability: The flexible tube body provides sufficient support to guide the endotracheal tube while possessing good flexibility, making it easy to adjust the insertion angle; the connecting housing provides a stable mounting base for internal electronic components, preventing the circuit connection from being affected when the tube body is bent, ensuring that the camera component continuously outputs clear images, and providing reliable visual support for the operator.

[0105] refer to Figure 9 In one possible implementation, the handle includes a wireless transmitter, and the display includes a wireless receiver, wherein...

[0106] The wireless transmitter and the wireless receiver are wirelessly connected. Specifically, the wireless connection can be any one of Wi-Fi, infrared, 4G / 5G / 6G.

[0107] Specifically, the beneficial effects include:

[0108] Completely eliminate cable constraints and optimize operating space: Traditional wired connections require cable transmission, which can easily lead to cable tangling and dragging, limiting operational flexibility. This solution uses wireless transmission technology, eliminating the physical connection between the handle and the display. Operators do not need to worry about cable interference and can freely adjust the handle grip angle and display placement, further expanding the range of operations and improving the convenience and comfort of cannulation operations.

[0109] Improve clinical collaboration efficiency: The wireless connection supports separate use of the monitor and the handpiece. The operator can place the monitor at the best viewing angle according to their own standing habits, while the assistant can also observe the laryngeal image on the monitor in the same space. This facilitates the completion of auxiliary operations such as suctioning and drug administration. Especially in emergency scenarios, it can effectively shorten the intubation time and improve team collaboration efficiency.

[0110] Enhanced equipment reliability and durability: Removing cables avoids cable wear and loosening caused by frequent bending and pulling, reducing potential failure points and extending equipment lifespan. Simultaneously, wireless transmission technology ensures stable image signal transmission, avoiding signal interference or interruptions that may occur with wired connections, guaranteeing operational continuity and safety.

[0111] refer to Figure 1 In one specific implementation, the display is provided with a TF card slot 17.

[0112] Specifically, the beneficial effects include:

[0113] Digital recording and archiving of surgical procedures: The TF card slot supports the insertion of storage media, enabling real-time recording and saving of dynamic video or high-definition images of laryngoscopy and intubation procedures directly to the TF card. This establishes a complete electronic record for each clinical procedure, facilitating hospital archiving, medical quality traceability, and postoperative review and summarization, meeting the requirements of modern smart hospitals for refined management of medical data.

[0114] Facilitating Teaching, Training, and Academic Exchange: The stored imaging data is an extremely valuable clinical teaching resource. Instructors can use these real intubation videos, especially cases involving difficult airways, to visually explain anatomical structures and surgical techniques to students or junior physicians. Simultaneously, medical staff can easily export this data for academic conferences, research paper writing, or the creation of teaching materials, greatly promoting the dissemination and advancement of medical technology.

[0115] Optimize workflows and enhance ease of use: Compared to the traditional method of exporting data via USB cable connection to a computer, TF card storage is more independent and faster. Users simply need to remove the card and insert it into the card reader or read it directly from the device to quickly copy and back up massive amounts of image data, eliminating the need for cumbersome driver installation and wiring, significantly improving clinical work efficiency.

[0116] Ensuring data security and privacy: Since the storage medium is a portable TF card, the hospital can adopt a management model of designated personnel for safekeeping and access as needed, ensuring the security of patient privacy data during transmission and storage, and preventing unauthorized access or leakage.
