[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views showing the device structure may be partially enlarged, not according to the usual proportions. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0019] Figs. 1-3 The diagram shown is a complete structural schematic of a general anesthesia dental splint according to this utility model. Please refer to [link / reference]. Figs. 1-3 The present embodiment of a general anesthesia dental pad includes a dental pad sleeve 100 formed by a first arc-shaped plate 110 and a second arc-shaped plate 120. The first arc-shaped plate 110 and the second arc-shaped plate 120 are hinged on one side. The inner sidewalls of the first arc-shaped plate 110 and the second arc-shaped plate 120 are provided with a plurality of teeth 130 distributed along their arc surfaces. The endotracheal tube passes through the inner side of the dental pad sleeve 100 and is squeezed and fixed by the teeth 130. The outer side of the dental pad sleeve 100 is also provided with a Velcro strap 300 for wrapping and fixing the first arc-shaped plate 110 and the second arc-shaped plate 120.

[0020] The first arc-shaped plate 110 and the second arc-shaped plate 120 are connected by a hinge 200, which allows the first arc-shaped plate 110 and the second arc-shaped plate 120 to rotate and open. It can be understood that the hinge 200 ensures that the first arc-shaped plate 110 and the second arc-shaped plate 120 are always in a movable connection state. This facilitates easy handling and intraoperative installation of the bite pad sleeve 100, preventing the upper and lower arc-shaped plates from shifting or slipping during use, and thus preventing the bite pad from causing undue pressure on the endotracheal tube. The inner diameter of the bite pad sleeve 100 is larger than the outer diameter of the endotracheal tube, and the cross-section of the bite pad sleeve 100 is a perfect circle. Here, when the bite pad sleeve 100 is closed around the endotracheal tube, the teeth 130 on the inner circumference of the bite pad sleeve 100 only form a certain degree of engagement with the outer side of the endotracheal tube, effectively preventing linear or radial slippage of the endotracheal tube without affecting normal ventilation.

[0021] In this embodiment, one end of the Velcro strap 300 is fixed to the outer wall of the first arc-shaped plate 110 or the second arc-shaped plate 120. One end of the Velcro strap 300 has a rough surface 310 on its outer side, and the other end has a hook surface 320 on its outer side. With the cooperation of the rough surface 310 and the hook surface 320, the Velcro strap 300 can be wrapped around the periphery of the dental pad sleeve 100 to quickly bind and fix the first arc-shaped plate 110 and the second arc-shaped plate 120, which is simple and easy to operate. Specifically, during use, after the endotracheal tube is inserted, the bite pad sleeve 100 can be directly inserted between the patient's upper and lower incisors, and the endotracheal tube can be placed inside the bite pad sleeve 100. The endotracheal tube is then secured by the bite teeth 130 on the inner surfaces of the first arc plate 110 and the second arc plate 120, preventing slippage between the tube and the bite pad. Subsequently, the Velcro strap 300 located outside the oral cavity is quickly wrapped around the bite pad sleeve 100, forming a stable cylindrical positioning structure. This completes the rapid installation of the bite pad. Compared with existing bite pad structures, it not only saves the total time of the endotracheal intubation operation and ensures the fixation effect, but also has the characteristics of simple structure and affordability compared to complex bite pads, making it suitable for widespread adoption.

[0022] Furthermore, the outer periphery of the dental pad sleeve 100 has annular protrusions 400 that are respectively fixed to the first arc-shaped plate 110 and the second arc-shaped plate 120. The annular protrusions 400 can limit the dental pad sleeve 100 inserted into the oral cavity, making its application more reasonable.

[0023] Furthermore, the outer side of the dental pad sleeve 100, located inside the oral cavity, also has anti-slip texture 140. The anti-slip texture 140 allows the patient's teeth to be securely embedded in the outer side of the dental pad sleeve 100, ensuring the stability of the dental pad and the catheter.

[0024] In summary, the general anesthesia dental pad of this embodiment allows for direct insertion of the dental pad sleeve 100 between the patient's upper and lower incisors and placement of the endotracheal tube inside the dental pad sleeve 100 after endotracheal tube insertion. The endotracheal tube is then secured by the bite teeth 130 on the inner surfaces of the first arc-shaped plate 110 and the second arc-shaped plate 120, preventing slippage between the tube and the dental pad. Subsequently, the Velcro strap 300 located outside the oral cavity is quickly wrapped around the dental pad sleeve 100, forming a stable cylindrical positioning structure. This completes the rapid installation of the dental pad. Compared to existing dental pad structures, this not only saves the total time of the endotracheal intubation procedure and ensures a secure fixation effect, but also offers the advantages of a simple structure and cost-effectiveness compared to more complex dental pads.

[0025] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
