This device features a dual-channel design, significantly improving ventilation efficiency and meeting the high requirements of anesthesiology. The fixing components ensure a secure connection between the connecting tube and the sealing cap, facilitating easy installation and disassembly. The configuration of the drainage channel and drainage tube effectively prevents saliva blockage, ensuring smooth ventilation. The thickened arc-shaped sleeve expands the oral cavity and presses against the base of the tongue, preventing channel blockage and improving safety. The lifting plate and arc-shaped protrusion design simplify the operation process and improve work efficiency. The soft rubber block and fixing holes enhance the stability and comfort of the device, reducing patient discomfort. Overall, this device boasts excellent performance and solves existing technical problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] In the description of this utility model, it should be understood that the terms "opening", "upper", "middle", "length", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0033] Example 1: Please refer to Figure 1-4 As shown, this embodiment provides a ventilation device, including:

[0034] Mounting plate 1 serves as the basic support component of the entire device, with a connecting pipe 2 fixedly running through one side. The connecting pipe 2 has two air delivery channels 8 inside, which are used to deliver airflow to the patient's mouth to provide necessary ventilation support.

[0035] A sealing cap 3 is designed at one end of the connecting pipe 2, which is sealed and engaged with one end of the connecting pipe 2. Two gas delivery pipes 4 are fixedly connected to both sides of the sealing cap 3. The other ends of these two gas delivery pipes 4 are connected to an external gas supply device, so that the airflow provided by the external gas supply device can be delivered to the patient's mouth through the gas delivery pipes 4 and the gas delivery channel 8.

[0036] To ensure a stable connection between the sealing cap 3 and the connecting pipe 2, this embodiment also includes a fixing assembly. The fixing assembly includes two fixing blocks 11, which are respectively fixedly installed on both sides of the connecting pipe 2. Simultaneously, sliding grooves 12 are provided on both sides of the sealing cap 3, and the two fixing blocks 11 are slidably connected to the inner walls of adjacent sliding grooves 12. Furthermore, a first fixing plate 13 and a second fixing plate 14 are respectively fixedly installed on both sides of the sealing cap 3, with the first fixing plate 13 located above the second fixing plate 14. The bottom of the second fixing plate 14 slidably engages with the top of the fixing blocks 11.

[0037] Furthermore, a single locking post 16 slides through the first fixing plate 13 and the second fixing plate 14 on the same side. The bottom end of the locking post 16 can slide through the corresponding fixing block 11, thereby locking and limiting the connection between the connecting pipe 2 and the sealing cap 3. To ensure that the locking post 16 can be stably held in the locked position, an abutment block 17 is fixedly sleeved on the outer wall of the locking post 16, and a spring 18 is also sleeved on the outer wall of the locking post 16. One end of the spring 18 is fixedly connected to the top of the abutment block 17, and the other end is fixedly connected to the bottom of the first fixing plate 13. In this way, the spring 18 can ensure that the bottom end of the locking post 16 can be continuously inserted into the corresponding fixing block 11, maintaining a stable connection between the sealing cap 3 and the connecting pipe 2.

[0038] To extract saliva from the patient's mouth, this embodiment includes a drainage channel 9 inside the connecting tube 2, located below the two air supply channels 8. An interface is fixedly installed at the bottom of the connecting tube 2, located outside the patient's mouth, with one end connected to the drainage channel 9. A drainage pipe 5 is fixedly connected to the drainage channel 9 via the interface, and the other end of the drainage pipe 5 is connected to an external suction device. Thus, the external suction device can extract saliva from the patient's mouth through the drainage pipe 5 and the drainage channel 9.

[0039] This application can be used in the field of anesthesiology, or in other fields applicable to this application.

[0040] Example 2: Reference Figure 1 , 2 4. Improvement based on Example 1: A multi-channel oropharyngeal ventilation device for anesthesiology, which is applied to the field of medical equipment technology;

[0041] To ensure the device can better adapt to the shape of the patient's mouth and avoid blockage of the two air delivery channels 8 inside the mouth, this embodiment also includes a curved thickened sleeve 10 fitted at one end of the connecting tube 2. The curved thickened sleeve 10 is located inside the patient's mouth and can fill and expand the patient's mouth while pressing on the base of the tongue to ensure the unobstructed flow of the air delivery channels 8.

[0042] To facilitate simultaneous movement of the two locking posts 16, this embodiment also includes a single lifting plate 15 fixedly fitted onto the outer wall of both locking posts 16. The lifting plate 15 is located at the top of the sealing cover 3. By lifting the lifting plate 15, the two locking posts 16 can be easily moved simultaneously, thereby completing the assembly and disassembly of the sealing cover 3 and the connecting pipe 2. Furthermore, an arc-shaped protrusion 19 is provided in the middle of the lifting plate 15, which facilitates lifting operations by medical personnel.

[0043] Finally, to stably fix the mounting plate 1 to the patient's head, soft rubber blocks 6 are fixedly installed on both sides of the mounting plate 1 in this embodiment. Each soft rubber block 6 has two fixing holes 7 inside, which can cooperate with external fixing straps to firmly fix the mounting plate 1 to the patient's head, ensuring the stability of the entire ventilation device.

[0044] The usage process and working principle of this utility model technical solution are as follows:

[0045] In use, medical staff can assemble the cleaned and disinfected connecting tube 2 and sealing cap 3. During installation, ensure that the drain tube 5 is fixed at the bottom of the connecting tube 2 and the two gas delivery tubes 4 are fixedly installed on one side of the sealing cap 3. Then, the user needs to lift the lifting plate 15 and then clip the sealing cap 3 onto one end of the connecting tube 2, ensuring that the fixing blocks 11 on both sides are engaged in the sliding grooves 12. After the two fixing blocks 11 are in place, stop pulling the lifting plate 15. At this time, under the action of the two springs 18, the two locking posts 16 can be engaged in the corresponding fixing blocks 11, thus completing the installation of the connecting tube 2 and the sealing cap 3. For disassembly, the user can reverse the above operations to quickly complete the installation of the connecting tube 2 and the sealing cap. The separation of section 3 facilitates cleaning and disinfection of the equipment. After installation, the user can use the multiple fixing holes 7 to install the fixing strap. Then, the end of the connecting tube 2 with the arc-shaped thickened sleeve 10 can be inserted into the patient's mouth, while ensuring that one side of the mounting plate 1 is tightly against the user's mouth. Afterward, the user can use the fixing holes 7 to fix the mounting plate 1 to the user's head, ensuring that the connecting tube 2 is not easily dislodged from the patient's mouth. During use, the external air supply device can deliver airflow through the air delivery pipe 4 to the air delivery channel 8, and then deliver the gas to the user's mouth again. At the same time, the external suction device can suction the saliva accumulated in the patient's mouth into the drainage channel 9, and finally discharge it through the drainage pipe 5, ensuring the patient's breathing effect is safe and stable.
