Description

Technical Field

[0001] The utility model relates to a laryngoscope blade, belonging to the field of medical devices. Background Art

[0002] Laryngoscope blades are a type of endoscope in the medical device field. They are generally used to guide tracheal intubation, and some are also used for oral examinations. They assist medical staff in observing and examining the patient's throat, helping to diagnose diseases such as pharyngitis and tonsillitis. They observe the movement of the vocal cords and glottis, assisting in the diagnosis of diseases such as vocal cord polyps and laryngeal cancer. During anesthesia and emergency treatment, they assist in tracheal intubation for anesthesia or emergency treatment. Traditional laryngoscope blades lack image display capabilities, only a light source. When using them, doctors use the light source of the laryngoscope blade to observe the glottis with the naked eye for intubation. This type of laryngoscope blade is extremely inconvenient to use and requires a high level of doctor experience. Furthermore, when intubating, doctors need to observe the position of the glottis closely, which also puts the doctor's face in closer contact with the patient, increasing the risk of infection. With the advancement of medical technology, video laryngoscope blades have become one of the essential medical devices in hospitals. The existing video laryngoscope blades include a display, a handle and a laryngoscope blade. The display and the handle are reusable, and the laryngoscope blade is disposable. However, when there are secretions in the patient's mouth or bleeding in the mouth of patients with maxillofacial or head trauma, the existing video laryngoscope blades will splash to the front end of the camera, making it impossible for the camera to observe the glottis. Therefore, the laryngoscope blade needs to be removed and wiped clean, but there is still a possibility that the camera will be blocked again, which is very inconvenient to use, reduces the success rate of intubation, increases the risk of intubation, and is not conducive to the observation of throat lesions. Utility Model Content

[0003] The purpose of the utility model is to provide a laryngoscope blade in order to overcome the shortcomings and deficiencies of the prior art.

[0004] A laryngoscope blade comprises a main body, the main body being provided with a camera channel for inserting a camera, the front side of the camera channel being provided with a sealing surface, and the main body being provided with an air blowing channel having a plurality of air holes connected to the main body. The air holes are used to blow away excess secretions adhering to the camera channel so that they no longer obstruct the camera. During oral or pharyngeal examinations or intubation, patients often secrete saliva, blood, or mucus. Once secretions or blood adhere to conventional video laryngoscope blades, the blades must be removed and wiped, interrupting the procedure and increasing the risk of intubation. The air blowing channel of the present invention is connected to the front end of the camera channel. Airflow ejected through the air holes immediately blows away excess secretions adhering to the front end of the lens. Combined with the suction port, this ensures that the camera is always clean and the field of view remains clear, eliminating the need for repeated removal and wiping of the laryngoscope blade, significantly improving operational continuity and efficiency. During use, the doctor simply blows air through a handle to keep the front end of the lens clean, eliminating the need to pause to replace or wipe the lens. This significantly improves intubation success rates and reduces intubation risks. Doctors simply blow air through the handle to keep the front of the lens clean, eliminating the need to pause to replace or clean the lens. This makes the entire intubation process simpler and smoother, shortening operation time, reducing intubation risks, and alleviating patient discomfort from repeated intubations, ultimately improving the patient experience.

[0005] Preferably, the main body is provided with a vertically arranged mounting portion, and the air blowing channel is arranged outside the mounting portion. The air blowing holes on the air blowing channel are evenly spaced on one side of the camera channel and face the sealing surface of the camera channel. The air blowing holes are evenly distributed along one side of the camera channel, and the air flow can evenly blow the sealing surface at the front end of the camera channel, avoiding "blind spots" or dead angles, effectively removing attached saliva, blood, and mucus, and ensuring that the camera remains clean at all times. The mounting portion provides stable support for the air blowing channel, ensuring that the airflow direction is always consistent with the sealing surface of the camera channel during blowing, reducing air blowing failures caused by shaking or positional offset, and improving reliability in clinical use.

[0006] Preferably, the insufflation channel is wide at the front and narrow at the back, with the insufflation holes located on the wider side of the mounting channel. The channel gradually widens from back to front, creating a "nozzle-diffuser" structure. This allows for a higher airflow at the end of the channel while maintaining sufficient insufflation pressure, thereby ensuring adequate airflow coverage while preventing discomfort to the patient caused by excessive airflow.

[0007] Furthermore, the insufflation channel is equipped with an insufflation port at the rear end, which connects to an external insufflation device. This port connects directly to the hospital's existing oxygen pipeline or other medical gas source, eliminating the need for an additional internal air pump or tank. This plug-and-play design enhances adaptability to various operating environments. The insufflation port utilizes a standardized connector design, enabling quick disassembly and installation. This facilitates separation of disposable components from external equipment, reduces the risk of cross-contamination, and facilitates routine cleaning and disinfection of the handle and tubing.

[0008] Preferably, a suction channel is provided on the top of the camera channel, and a suction port is provided on the suction channel facing the oral cavity. The suction port is used to cooperate with the air blowing hole to simultaneously suck out excess secretions to prevent them from blocking the camera again. The air blowing channel is responsible for initially blowing away the secretions, while the suction channel can simultaneously suck out the scattered saliva, blood, mucus, etc., to prevent them from gathering again in the oral cavity or in front of the lens, thereby achieving a more thorough cleaning effect. The suction port faces the oral cavity, and can timely aspirate the accumulated fluid, inhibit the interference of excessive liquid in the oral cavity on the lens and the surgical field of view, maintain a clear field of view, and reduce the need for medical staff to wipe twice. The specially designed top suction port and the side air blowing hole complement each other, and the air flow and negative pressure do not interfere with each other. The suction direction and the blowing direction can be precisely controlled to avoid blowing the secretions to areas that do not need to be cleaned or inhaled into the trachea.

[0009] Preferably, auxiliary suction ports connected to the suction channel are provided on either side of the suction port. These auxiliary suction ports, located on either side of the main suction port, can simultaneously capture secretions near both sides, preventing residual liquid from accumulating in the main suction port and preventing timely aspiration. This ensures that secretions from all directions in the mouth are effectively removed. The multi-point simultaneous suction design allows for rapid removal of large amounts of secretions, and working in conjunction with the insufflation channel, speeds up the cleaning process, helping to shorten intubation or examination time and improve clinical efficiency.

[0010] Furthermore, the tail of the suction channel is equipped with a suction port that connects to an external suction device. With the help of an adjustable valve or flow meter on the external device, medical staff can accurately match the suction strength according to the patient's condition and the viscosity of the secretions, ensuring both cleaning effect and comfort and safety.

[0011] Preferably, the rear end of the imaging channel is equipped with a snap-on mechanism for attaching the camera. This dedicated snap-on mechanism ensures the camera maintains the correct axial and radial position within the channel, preventing image shift or blurring due to vibration or slippage during use. The disposable snap-on design facilitates quick removal, replacement, or maintenance of the camera without the need for additional tools, reducing clinical maintenance costs and minimizing the risk of cross-contamination.

[0012] Preferably, the main body is provided with an extension located in front of the camera channel, with the end of the extension forming a circular protrusion. This arc-shaped extension provides initial force bearing upon initial contact with the patient's oral or pharyngeal tissue, preventing the camera lens from directly colliding with the mucosa or teeth, and reducing the risk of lens scratches, breakage, or wear on the surface sealing surface. The extension guides the lips and tongue root along the arc, allowing the camera channel to align with the curve of the larynx, achieving a more natural visual angle, improving field of view coverage and image quality.

[0013] Furthermore, the main body and camera channel are made of transparent material. The transparent material enables medical personnel to observe liquid, bubbles or blockage in the insufflation and suction channels from the side or backlight, and promptly detect and deal with channel blockage or failure, ensuring continuous and reliable cleaning function.

[0014] The present invention has the following beneficial effects: During oral or pharyngeal examinations or intubation, patients often secrete saliva, blood, or mucus. Conventional video laryngoscope blades, once clinging to secretions or blood, require removal and wiping, interrupting the procedure and increasing the risk of intubation. The present invention features an air insufflation channel connected to the front of the camera channel. Airflow ejected through the air insufflation port instantly dissipates excess secretions adhering to the front of the lens. Combined with the suction port, the camera remains clean and the field of view remains clear, eliminating the need for repeated removal and wiping of the laryngoscope blade. This significantly improves operational continuity and efficiency. During use, the doctor simply blows air through the handle to keep the front of the lens clean, eliminating the need to pause to replace or wipe the lens. This significantly improves intubation success rates and reduces intubation risks. The doctor simply blows air through the handle to keep the front of the lens clean, eliminating the need to pause to replace or wipe the lens. This makes the entire examination and intubation process simpler and more streamlined. This shortens operation time, reduces intubation risks, and reduces patient discomfort caused by repeated intubation, thus optimizing the patient experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0023] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for the purpose of distinguishing two non-identical entities or non-identical parameters with the same name. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. Subsequent embodiments will not explain this one by one.

[0024] The directional and positional terms used in this invention, such as "upper," "lower," "front," "back," "left," "right," "inner," "outer," "top," "bottom," and "side," are used solely to refer to the directions or positions in the accompanying drawings. Therefore, the directional and positional terms used are intended to illustrate and facilitate understanding of this invention and are not intended to limit the scope of protection of this invention.

[0025] like Figure 1-5The figure shows an embodiment of a laryngoscope blade of the present invention, comprising a main body 1, wherein the main body 1 is provided with a camera channel 2 for inserting a camera, the front side of the camera channel 2 being provided with a sealing surface, the main body 1 being provided with an air blowing channel 3, and the air blowing channel 3 being provided with a plurality of air blowing holes 31 connected to the main body 1, the air blowing holes 31 being used to blow away excess secretions attached to the camera channel 2 so that they no longer block the camera. During oral or pharyngeal examinations or intubation, patients often secrete saliva, blood, or mucus. Once a traditional video laryngoscope is adhered to secretions, it needs to be removed and wiped, which easily interrupts the operation and increases the risk of cross-infection. The air blowing channel 3 of the present invention is connected to the front end of the camera channel 2, and the air flow ejected through the air blowing holes 31 can immediately blow away excess secretions attached to the front end of the lens, so that the camera is always kept clean and the field of view is continuously clear, without the need to repeatedly remove the laryngoscope blade for wiping, thereby significantly improving the continuity and efficiency of the operation. Doctors only need to blow air through the handle to keep the front of the lens clean, without having to pause to replace or wipe the lens. This makes the entire intubation process simpler and smoother, shortening operation time and reducing patient discomfort caused by repeated intubation, thus optimizing the medical experience.

[0026] The main body 1 is provided with a vertically arranged mounting portion 11, and the air blowing channel 3 is arranged outside the mounting portion 11. The air blowing holes 31 on the air blowing channel 3 are evenly spaced on one side of the camera channel 2 and face the sealing surface of the camera channel 2. The air blowing holes 31 are evenly distributed along one side of the camera channel 2, and the air flow can evenly blow the sealing surface at the front end of the camera channel 2, avoiding "blind spots" or dead corners, effectively removing attached saliva, blood, and mucus, and ensuring that the camera is always kept clean. The mounting portion 11 provides a stable support for the air blowing channel 3, so that the airflow direction is always consistent with the sealing surface of the camera channel 2 during blowing, reducing air blowing failures caused by shaking or position offset, and improving the reliability of clinical use.

[0027] The insufflation channel 3 is wide at the front and narrow at the back, with the insufflation hole 31 located on the wider side of the installation channel. The channel gradually widens from back to front, creating a "nozzle-diverging" structure. This allows for a higher airflow rate at the end of the channel while maintaining sufficient insufflation pressure, ensuring adequate airflow coverage while preventing discomfort to the patient caused by excessive airflow.

[0028] The insufflation channel 3 is terminated with an insufflation port 32 for connection to an external insufflation device. This port connects directly to the hospital's existing oxygen pipeline or other medical gas source, eliminating the need for an additional internal air pump or tank. This plug-and-play design enhances adaptability to various operating environments. The insufflation port 32 utilizes a standardized connector design, enabling quick disassembly and installation. This facilitates separation of disposable components from external equipment, reduces the risk of cross-contamination, and facilitates routine cleaning and disinfection of the handle and tubing.

[0029] In the embodiment of the present application, this embodiment is different from the above-mentioned embodiment in that a suction channel 4 is provided on the top of the camera channel 2, and a suction port 42 facing the oral cavity is provided on the suction channel 4. The blowing channel 3 is responsible for initially blowing away the secretions, while the suction channel 4 can simultaneously suck out the scattered saliva, blood, mucus, etc., to prevent them from gathering again in the oral cavity or in front of the lens, thereby achieving a more thorough cleaning effect. The suction port 42 faces the oral cavity, and can timely aspirate the accumulated fluid, inhibit the interference of excessive liquid in the oral cavity on the lens and the surgical field of view, maintain a clear field of view, and reduce the need for medical staff to wipe twice. The specially designed top suction port 42 and the side blowing hole 31 complement each other, and the air flow and negative pressure do not interfere with each other. The suction direction and the blowing direction can be precisely controlled to avoid blowing the secretions to areas that do not need to be cleaned or inhaled into the trachea.

[0030] Auxiliary suction ports 43, connected to the suction channel 4, are located on either side of the main suction port 42. These auxiliary suction ports 43 simultaneously capture secretions near both sides, preventing residual fluid from accumulating in the main suction port and preventing timely aspiration. This ensures that secretions from all directions in the mouth are effectively removed. This multi-point simultaneous suction design allows for rapid removal of large amounts of secretions. Working in conjunction with the insufflation channel 3, this speeds up the cleaning process, helping to shorten intubation or examination time and improve clinical efficiency.

[0031] The tail of the suction channel 4 is provided with a suction port 41 connected to an external suction device. With the help of a regulating valve or flow meter on the external device, medical staff can accurately match the suction strength according to the patient's condition and the viscosity of the secretions, ensuring both cleaning effect and comfort and safety.

[0032] In this embodiment of the present application, unlike the previous embodiments, a buckle 21 is provided at the rear of the imaging channel 2 to engage the camera. This dedicated buckle mechanism ensures the camera maintains the correct axial and radial position within the channel, preventing image shift or blurring due to vibration or slippage during use. The disposable buckle design facilitates quick removal, replacement, or maintenance of the camera without the need for additional tools, reducing clinical maintenance costs and the risk of cross-contamination.

[0033] In the embodiment of the present application, this embodiment differs from the above-mentioned embodiment in that the main body 1 is provided with an extension portion 12 located in front of the camera channel 2, and the end of the extension portion 12 is in the shape of a protruding arc. The arc-shaped protruding extension portion 12 can bear the force first when it first contacts the patient's oral or pharyngeal tissue, preventing the camera lens from directly colliding with the mucosa or teeth, and reducing the risk of lens scratches, breakage, or wear on the surface sealing surface. The extension portion 12 guides the lips and tongue root to slide along the arc, allowing the camera channel 2 to align with the curve of the throat, achieving a more natural line of sight incident angle, and improving the field of view coverage and image quality.

[0034] The main body 1 and the camera channel 2 are made of transparent material. The transparent material enables medical staff to observe the liquid, bubbles or blockage in the insufflation and suction channels from the side or backlight, and promptly detect and deal with channel blockage or failure, ensuring continuous and reliable cleaning function.

[0035] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.

[0036] Although the present invention has been described with reference to several specific embodiments, it should be understood that the present invention is not limited to the specific embodiments disclosed, and the present invention is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
