Description

Technical Field

[0001] This application relates to the field of medical device technology, specifically to a video laryngeal slide with a laryngeal anesthesia tube. Background Technology

[0002] In clinical anesthesia, endotracheal intubation is required for airway management. During endotracheal intubation, local anesthetic is sprayed onto the epiglottis, vocal cords, and other laryngeal structures to improve the patient's tolerance to intubation stimulation and reduce cardiovascular response, thereby achieving a smooth intubation.

[0003] Currently, because video laryngoscopes lack an anesthetic access, performing topical anesthesia of the larynx before endotracheal intubation under video laryngoscopes requires two people: one to expose various anatomical locations of the larynx through the video laryngoscope, and the other to spray local anesthetic through the laryngeal anesthesia tube. This method cannot be performed by a single person; it requires skilled cooperation between two people, making the operation inconvenient and cumbersome. Utility Model Content

[0023] See attached document Figure 1 and Figure 2 As shown, this application embodiment provides a video laryngoscope with a laryngeal anesthesia tube, including a video laryngoscope body. An endotracheal tube fixing channel 2 is provided along one side of the video laryngoscope body for fixing the endotracheal tube. An laryngeal anesthesia tube fixing channel 3 is provided along the other side of the video laryngoscope body for fixing the laryngeal anesthesia tube 4. The laryngeal surface is anesthetized before endotracheal intubation under video laryngoscope guidance. By installing the laryngeal anesthesia tube 4 into the laryngeal anesthesia tube fixing channel 3, the laryngeal anesthesia tube 4 enters along with the video laryngoscope when it is inserted into the larynx. This eliminates the need for a separate person to insert the laryngeal anesthesia tube 4, allowing one person to complete the use of the video laryngoscope and laryngeal surface anesthesia, greatly facilitating medical personnel operation.

[0024] In this embodiment, as Figure 3 and Figure 4As shown, the laryngeal tube fixing channel 3 includes a channel base 301 and a channel cover 302. The channel base 301 is integrally formed on the laryngeal tube 4, and the channel cover 302 is detachably fastened to the channel base 301. A laryngeal tube mounting groove 303 is provided along the channel base 301 and the channel cover 302. The conventional existing laryngeal anesthesia tube 4 includes a tube body, an atomizing nozzle, and a connector. The tube body is installed in the laryngeal anesthesia tube mounting groove 303, and the atomizing nozzle and the connector are located outside the laryngeal anesthesia tube mounting groove 303. The aperture of the laryngeal anesthesia tube mounting groove 303 is smaller than the outer diameter of the atomizing nozzle, and the outer diameter of the tube body is smaller than the inner diameter of the laryngeal anesthesia tube mounting groove 303. This allows the laryngeal anesthesia tube 4 to be moved back and forth on one side of the connector to adjust its position for anesthesia spraying. At the same time, because the aperture of the laryngeal anesthesia tube mounting groove 303 is smaller than the outer diameter of the atomizing nozzle, the atomizing nozzle can always be kept outside the laryngeal anesthesia tube fixing channel 3, preventing the atomizing nozzle from retracting into the laryngeal anesthesia tube fixing channel 3 and obstructing the spraying of anesthetic.

[0025] Specifically, to achieve a detachable connection between the channel cover 302 and the channel base 301, such as Figure 4 As shown, the top surface of the fixed base is provided with a recessed groove 304, and multiple slots 306 are provided along the side of the recessed groove 304. The bottom surface of the channel cover plate 302 is provided with a protrusion 305 that inserts into the recessed groove 304. The side of the protrusion 305 is provided with a locking block 307 that corresponds one-to-one with the slot 306. The locking block 307 is locked into the slot 306. As can be imagined, since the laryngeal tube installation groove 303 is provided along the channel base 301 and the channel cover 302, the fixed base and the fixed cover form a thin-walled structure. When it is necessary to install the laryngeal tube 4 on the video laryngoscope, the laryngeal tube 4 is placed into the laryngeal tube installation groove 303 of the channel base 301. By pressing the two sides of the channel cover 302, the protrusion 305 is retracted inward. Then, it is inserted into the recess 304 and released. The locking block 307 is then locked into the locking groove 306, thereby fixing the channel cover 302 on the channel base 301 and fixing the laryngeal tube 4 on the video laryngoscope. Conversely, when it is necessary to remove the laryngeal tube 4 from the laryngoscope, by pressing the two sides of the channel cover 302, the protrusion 305 is retracted inward. After the locking block 307 is released from the locking groove 306, the channel cover 302 can be lifted to separate from the channel base 301, and the laryngeal tube 4 can be removed from the video laryngoscope.

[0026] Of course, in a preferred embodiment, to avoid scratching the throat, such as Figure 3 and Figure 4 As shown, the channel cover 302 is provided with an arc-shaped edge 308, which makes smooth contact with the throat and avoids scratching the throat.

[0027] In summary, the video laryngoscope with a laryngeal anesthesia tube proposed in this application provides a laryngeal anesthesia tube fixing channel 3 on one side of the video laryngoscope relative to the endotracheal intubation fixing channel 2. The laryngeal anesthesia tube 4 is fixed to the video laryngoscope through the laryngeal anesthesia tube 4 channel, so that the laryngeal anesthesia tube 4 can be inserted into the larynx along with the video laryngoscope. One person can perform anesthetic spraying on the larynx while using the video laryngoscope, which is convenient to operate. Furthermore, since the laryngeal anesthesia tube fixing channel 3 is composed of a detachable and interlocking channel base 301 and a channel cover 302, it is convenient to install the laryngeal anesthesia tube 4 onto the video laryngoscope and convenient to remove the laryngeal anesthesia tube 4 from the video laryngoscope.

[0028] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
