DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the utility model.

[0025] Please refer to Figures 1-4 ​A pharyngeal ventilation device for anesthesiology includes a fixation plate 1, a bite block 2, an air tube 3, an adjustment strap 4, a locking device, an unlocking device, and an adjustment device. The bite block 2 is mounted on one side of the fixation plate 1, and the air tube 3 is mounted on the end of the bite block 2 away from the fixation plate 1. The left and right ends of the fixation plate 1 are connected to the adjustment strap 4 via the locking device. The locking device includes a positioning block 5, a wedge groove 6, a positioning groove 7, a movable groove 8, a wedge block 9, a sliding groove 10, a slider 11, and a spring 12. The positioning blocks 5 are fixedly mounted on both ends of the adjustment strap 4. The positioning grooves 7 are formed on both ends of the fixation plate 1. The positioning grooves 7 and the positioning blocks 5... The positioning block 5 has a wedge-shaped groove 6 on one side wall, and a movable groove 8 on one side wall of the positioning groove 7. A wedge-shaped block 9 is slidably installed in the movable groove 8. Two sets of sliding grooves 10 are symmetrically arranged in the movable groove 8 around the central axis of the wedge-shaped block 9. A slider 11 is fixedly installed at both ends of the wedge-shaped block 9. The slider 11 and the sliding groove 10 are slidably connected. A spring 12 supporting the slider 11 is installed in the sliding groove 10. An unlocking device is installed directly above the movable groove 8. In this embodiment, after the patient's mouth is opened, the dental pad 2 and the air tube 3 are placed in the patient's mouth. The air tube 3 extends into the patient's mouth, and the dental pad 2... The band is securely placed between the upper and lower teeth. Then, the length of the adjustment band 4 is adjusted according to the patient's head size using an adjustment device (the adjustment band 4 is made of elastic material, reducing the number of adjustments needed for patients with small head differences). The two ends of the adjustment band 4 are fixed to the left and right sides of the fixing plate 1 using a locking device. Specifically, the positioning blocks 5 at the left and right ends of the adjustment band 4 are aligned with the positioning grooves 7 on the fixing plate 1. When the positioning blocks 5 are inserted into the positioning grooves 7, they first contact the wedge-shaped blocks 9. Under the force of the positioning blocks 5, the wedge-shaped blocks 9 drive the slider 11 to compress the spring 12 within the slide groove 10, causing the spring 12 to compress within the slide groove 10. Subsequently, the wedge-shaped blocks 9 retract into the movable groove 8. When the wedge block 9 is aligned with the wedge groove 6, due to the action of the spring 12, the wedge block 9 will automatically slide into the wedge groove 6 under the pushing force of the spring 12, completing the locking action. At this time, the positioning block 5 is firmly fixed in the positioning groove 7 to prevent it from accidentally sliding out, thus completing the fixing. Through the design of the wedge block 9 and the wedge groove 6, the locking device ensures that once the positioning block 5 is inserted into the positioning groove 7, it will not easily loosen unless the unlocking device is manually operated. The continuous pressure provided by the spring 12 ensures that the wedge block 9 always fits tightly against the wedge groove 6, further enhancing the reliability of the locking and avoiding loosening or displacement caused by external forces. This design significantly improves the safety of the equipment, which is especially crucial during surgery.

[0026] In practical use, to further facilitate the unlocking of the positioning block 5, in this embodiment, the unlocking device includes a rectangular groove 13 and a rectangular plate 14. The top walls of both the left and right ends of the fixed plate 1 are provided with rectangular grooves 13 that pass through the movable groove 8. The rectangular plate 14 is slidably installed in the rectangular groove 13. The bottom wall of the rectangular plate 14 is fixedly connected to the top wall of the wedge block 9. When it is necessary to unlock the positioning block 5, medical staff only need to push the rectangular plate 14 located outside the fixed plate 1. As the rectangular plate 14 is pushed inward, it will drive the wedge block 9 fixedly connected to its bottom wall to move away from the end of the wedge block 9, thereby causing the wedge block 9 to exit from the wedge groove 6. This action releases the locked state of the positioning block 5, allowing the positioning block 5 to be easily removed from the positioning groove 7, thereby realizing the unlocking of the adjusting belt 4 and the fixed plate 1. The unlocking function can be realized by simply pushing the rectangular plate 14, which greatly simplifies the operation steps and allows medical staff to operate more quickly and efficiently.

[0027] In practical use, to further facilitate the adjustment of the length of the adjustment band 4, in this embodiment, the adjustment device includes an adjustment buckle 15, which is installed on the side wall of the adjustment band 4. Each patient's physiological structure is different. By adjusting the length of the adjustment band 4 (the adjustment band 4 is double-layered), the device can better fit each patient and provide a more personalized treatment plan. The correct length of the adjustment band 4 can ensure that the device is stable and prevent displacement during the operation, thereby ensuring unobstructed airway and improving the safety of the operation.

[0028] In actual use, the movement of the slider 11 is further guided. In this embodiment, a guide rod 16 is fixedly installed in the slide groove 10. The guide rod 16 and the slider 11 are slidably connected. The guide rod 16 ensures that the slider 11 can move smoothly and accurately along the predetermined path, avoiding the slider 11 from deviating or getting stuck due to external force or improper operation. By providing a stable guiding mechanism, the shaking of the slider 11 in the slide groove 10 can be effectively reduced, thereby ensuring that the entire locking and unlocking process is more stable and reliable.

[0029] Preferably, in this embodiment, the ventilation tube 3 has a curved design, which better conforms to the natural curve of the human throat, reduces irritation and pressure on the throat and surrounding tissues, and improves patient comfort.

[0030] Preferably, in this embodiment, the top of the fixing plate 1 is provided with an arc-shaped groove 17. The design of the arc-shaped groove 17 can better fit the facial curve of the face, avoid the rigid pressure caused by the fixing plate 1 on the patient, and reduce discomfort.

[0031] Preferably, in this embodiment, both the groove 10 and the slider 11 are cylindrical. The contact area between the cylindrical slider 11 and the groove 10 is relatively small, which helps to reduce friction and makes the slider 11 move more smoothly and fluidly within the groove 10.

[0032] Preferably, in this embodiment, a lever 18 is fixedly installed at the top of the rectangular plate 14. The outer surface of the lever 18 is provided with anti-slip texture. The presence of the lever 18 makes it easier for medical staff to apply force to push or pull the rectangular plate 14, thereby unlocking the locking device. Compared with directly operating the rectangular plate 14, the lever 18 provides a larger contact area and a more comfortable grip point. The anti-slip texture increases the friction between the fingers and the lever 18, ensuring that each operation is accurate.
