[0029] Please refer to Figure 1 and Figure 2 , a disposable high-flow oral oxygen inhalation tube provided by an embodiment of the present utility model includes an oral breathing nozzle 100 and an oxygen delivery tube 200. The oral breathing nozzle 100 includes a breathing tube 110, a lip baffle 120, and a connecting tube 130. The breathing tube 110 is detachably connected to the connecting tube 130. When the breathing tube 110 is connected to the connecting tube 130, the lip baffle 120 is clamped and fixed between the breathing tube 110 and the connecting tube 130. One end of the oxygen delivery tube 200 is connected to the connecting tube 130.

[0030] Oxygen is input through the oxygen delivery tube 200. The oxygen enters the breathing tube 110 through the connecting tube 130. When the patient holds the breathing tube 110 in the mouth, the lip baffle 120 adheres to the patient's lips to avoid going deep into the oral cavity. The oxygen delivery tube 200, the connecting tube 130, and the breathing tube 110 form a passage, enabling oxygen to be input into the patient's oral cavity, thereby avoiding the conflict of sharing the operation channel in the transnasal approach during clinical painless fiberoptic bronchoscopy examination and preventing hypoxemia during the examination.

[0031] As Figure 3 and Figure 4 shown, in this embodiment, the connecting tube 130 has a threaded portion 131, and a threaded connection section that is in threaded engagement with the threaded portion 131 is provided on the inner peripheral side of the breathing tube 110. The connecting tube 130 and the breathing tube 110 are connected by threaded engagement.

[0032] The connection of the connecting tube 130 to the breathing tube 110 through the threaded portion 131 enables the breathing tube 110 to be disassembled. According to the opening degree of the patient's mouth, a breathing tube 110 with a suitable diameter can be selected to meet the needs of different patients.

[0033] Furthermore, the radius of the connecting tube 130 is greater than the radius of the threaded portion 131. The middle part of the lip baffle 120 has a through hole, and the radius of the through hole is between the radius of the connecting tube 130 and the radius of the threaded portion 131. When the threaded portion 131 passes through the through hole and is connected to the breathing tube 110, the lip baffle 120 is fixed between the breathing tube 110 and the connecting tube 130.

[0034] When the radius of the threaded portion 131 is smaller than the radius of the through hole, the threaded portion 131 of the connecting tube 130 can smoothly pass through the through hole and be connected to the breathing tube 110, while the radius of the connecting tube 130 being greater than the through hole prevents the connecting tube 130 from passing through the through hole of the lip baffle 120. Further, when the connecting tube 130 is connected to the breathing tube 110, the lip baffle 120 and the connecting tube 130 have a certain contact surface, so that the lip baffle 120 can be locked and fixed.

[0035] Even further, the radius of the breathing tube 110 is greater than the radius of the through hole. In order to fix the lip baffle 120 between the connecting tube 130 and the breathing tube 110 when the connecting tube 130 is connected to the breathing tube 110, by setting the radius of the breathing tube 110 to be greater than the through hole, the through hole of the lip baffle 120 cannot pass through the breathing tube 110, thus realizing the fixation of the lip baffle 120 when connecting the breathing tube 110 and the connecting tube 130.

[0036] In this embodiment, the lip baffle 120 is arc-shaped. When the patient holds the breathing tube 110 in the mouth, the breathing tube 110 can be prevented from going deep into the oral cavity through the lip baffle 120, and its arc-shaped setting fits the patient's facial contour better.

[0037] Furthermore, an occlusal pad 112 is provided on the outer circumferential surface of the breathing tube 110. When the occlusal pad 112 is provided on the breathing tube 110, when the patient holds the breathing tube 110 in the mouth, the patient's teeth will bite on the breathing tube 110. To avoid damage to the teeth or deformation of the breathing tube 110 due to unconscious biting, the occlusal pad 112 can play a protective role. Even further, the occlusal pad 112 can be made of silica gel material to ensure its good safety.

[0038] In this embodiment, a flange 111 is provided on one side of the breathing tube 110 away from the lip flap 120. The provision of the flange 111 can prevent the patient from easily spitting out the breathing tube 110. Further, the radius of the flange 111 is greater than the radius of the bite pad 112. When the patient bites on the bite pad 112, the tooth biting position is between the flange 111 and the lip flap 120, thereby preventing the mouthpiece 100 from detaching from the patient's oral cavity.

[0039] It should be noted that the other end of the oxygen delivery tube 200 is connected with an oxygen delivery tube joint 210 for connecting with an external oxygen supply device. For example, the oxygen delivery tube 200 is connected with a ventilator through the oxygen delivery tube joint 210, so that the ventilator supplies oxygen to the patient through the oxygen delivery tube 200 and the mouthpiece 100.

[0040] In this embodiment, one end of the lip flap 120 is connected with an elastic band 300, and the other end of the elastic band 300 is connected with the other end of the lip flap 120 to form a closed structure.

[0041] Through the provision of the elastic band 300, when the patient holds the mouthpiece 100 in the mouth, it can be fixed to the patient's head, further preventing the mouthpiece 100 from detaching.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
