[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] Example:

[0034] See Figure 1 , Figure 2 and Figure 3 This embodiment discloses an oropharyngeal ventilation tube for anesthesia, including a baffle 10, a support tube 20, a flexible tube 30, and a support rod 40. The baffle 10 has a through hole in its center, and the support tube 20 is also located in the center of the baffle 10, with the through hole on the baffle 10 located inside the support tube 20.

[0035] A flexible hose 30 is installed in the through hole of the baffle 10. One end of the hose 30 is connected to the baffle 10 and communicates with the through hole, while the other end of the hose 30 is detachably connected to one end of a support rod 40. The support rod 40 is located inside the hose 30, and its other end protrudes from the through hole in the baffle 10. Multiple support points are located between the middle of the support rod 40 and the inner wall of the hose 30.

[0036] In this embodiment, by providing a flexible tube 30 on the baffle 10 and detachably placing the support rod 40 inside the flexible tube 30, the flexible tube 30, the baffle 10 and the support rod 40 are packaged together during packaging. The flexible tube 30 is bent within the lateral space occupied by the baffle 10, and the support rod 40 is also packaged within the lateral space.

[0037] In use, the support rod 40 is passed through the through hole and brought into contact with the inner wall of the hose 30, and the end of the support rod 40 is connected to the end of the hose 30, so that the hose 30 can be smoothly inserted into the patient's throat.

[0038] This technical solution can solve the problem that traditional oropharyngeal ventilation tubes occupy a lot of ineffective space in the packaging, resulting in low utilization of storage space.

[0039] Preferably, the baffle 10 is elliptical in shape and the surface of the baffle 10 is arc-shaped. This design allows it to fit the shape of the patient's mouth, avoiding a large contact area between the baffle 10 and the patient's skin, thus avoiding other complications, such as inflammation caused by prolonged contact with the patient's skin.

[0040] In addition, the baffle 10 is provided with two elastic bands 50, the two ends of which are connected to the two ends of the baffle 10 respectively, so that the baffle 10 can be put on the patient's head through the elastic bands 50.

[0041] In one specific embodiment:

[0042] The support tube 20 is an elliptical tube. The end of the support tube 20 away from the baffle 10 has an arc-shaped structure. The function of the support tube 20 is to support the patient's teeth and prevent the patient's teeth from biting the flexible tube 30, thereby reducing the effective cross-sectional area of ​​the flexible tube 30.

[0043] In another specific embodiment:

[0044] The support rod 40 includes multiple arc-shaped rods 41. One end of each arc-shaped rod 41 is detachably connected to one end of the hose 30. All arc-shaped rods 41 are located inside the hose 30, and there are multiple support points between the middle of the arc-shaped rod 41 and the hose 30, thereby providing support for the hose 30.

[0045] Preferably, the support rod 40 further includes a support ring 42 and an inner ring 43, wherein one end of all the arc-shaped rods 41 is connected to the support ring 42, and an inner ring 43 is provided in the middle of all the arc-shaped rods 41. The support ring 42 is detachably connected to the end of the hose 30, and the inner ring 43 is in contact with the inner wall of the hose 30.

[0046] In this embodiment, all the arc-shaped rods 41 are evenly distributed inside the hose 30. The support ring 42 enables the detachable connection between the support rod 40 and the hose 30. The inner tube enables the support rod 40 to support the inner wall of the hose 30.

[0047] Preferably, a connecting ring is provided at the end of the hose 30. The connecting ring can be sleeved on the support ring 42. Specifically, the connecting ring is provided at the end of the hose 30, and the support ring 42 has multiple notches. The connecting ring is sleeved on the support ring 42 through the notches on the support ring 42, thereby realizing the quick installation of the connecting ring and the support ring 42.

[0048] In another specific embodiment:

[0049] The support ring 42 is provided with multiple inner rings 43, which provide support for multiple points on the inner wall of the hose 30.

[0050] In another specific embodiment:

[0051] The support rod 40 also includes a connecting plate 44, which is annular and has a hollow structure in the middle. The connecting plate 44 is connected to the end of all the arc rods 41 away from the support ring 42, and the surface of the connecting plate 44 is arc-shaped, which can match the surface of the baffle 10.

[0052] After the support rod 40 is installed, the connecting plate 44 covers the baffle 10 to prevent the exposed end of the arc rod 41 from causing injury to medical staff.

[0053] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
