[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] like Figures 1-5 As shown, this utility model proposes an endotracheal tube fixation device, which mainly includes an arc-shaped bracket 1, a strap 2, an installation tube 3, a locking assembly 4, a swivel ring 5, a support block 13, and a pressure plate 15.

[0034] There are two straps 2, one end of which is fixedly connected to both ends of the arc-shaped bracket 1, and the other end of each strap 2 is provided with Velcro 16. The Velcro 16 of the two straps 2 are glued together. The straps 2 are used to fix the fixator to the patient's head, thereby enhancing the fixation effect. The ends of the straps 2 are glued with Velcro 16, which facilitates the wearing and removal of the fixator, and can be flexibly adjusted according to the size of the patient's head.

[0035] The mounting tube 3 is mounted on the arc-shaped bracket 1, and an opening is provided on the side of the mounting tube 3 to facilitate the entry of the air tube into the mounting tube 3 through the opening. The upper side wall of the installation tube 3 has a slot 7 that communicates with the inside of the installation tube 3. The locking assembly 4 is located at the slot 7 and is used to lock the air tube inside the installation tube 3. Specifically, the locking assembly 4 includes a flexible plate 41, an installation block 43, a clamping plate 44 and a thrust spring 46. One end of the flexible plate 41 is fixedly connected to the side wall of the slot 7, and multiple ratchet teeth 42 are arranged on the outer wall of the other end. The flexible plate 41 is used to wrap around the slot 7. The installation block 43 is slidably mounted on the arc-shaped bracket 1. The installation block 43 is fixedly connected to the installation tube 3 and is located on one side of the slot 7. The installation block 43 has an installation groove for the flexible plate 41 to pass through. The middle part of the clamping plate 44 is rotatably mounted on the installation block 43, and a pawl 45 for unidirectional engagement with the ratchet teeth 42 is provided on the side of one end near the installation groove. One end of the thrust spring 46 is rotatably connected to the other end of the clamping plate 44, and the other end of the thrust spring 46 is rotatably connected to the installation block 43.

[0036] The rotating ring 5 is C-shaped, and an annular groove 6 is provided on the lower side wall of the installation tube 3. The rotating ring 5 is slidably disposed in the annular groove 6. The opening width of the rotating ring 5 is greater than or equal to the opening width of the installation tube 3. When the trachea is inserted into the installation tube 3, the opening of the rotating ring 5 coincides with the opening of the installation tube 3. After the trachea is inserted into the installation tube 3, the rotating ring 5 is rotated so that the opening of the rotating ring 5 is moved away from the opening of the installation tube 3 and is located on the side of the installation tube 3 away from the opening. This helps to block the trachea at the opening of the installation tube 3 and prevent the trachea from moving out from the lower opening of the installation tube 3, further enhancing the stability of the trachea installation. A beeswax layer (not shown in the figure) is fixedly provided on the outer side wall of the rotating ring 5 for contact with the mouth. The beeswax layer is soft and can improve the comfort of the patient's mouth when in contact. The rotating ring 5 can rotate relative to the installation tube 3, which can better adapt to the movement of the patient's mouth.

[0037] The mounting tube 3 is slidably mounted on the arc-shaped bracket 1. Specifically, an arc-shaped slide rail 8 is fixedly mounted on the outer side of the arc-shaped bracket 1. Multiple protrusions 9 are arranged circumferentially on the side of the arc-shaped slide rail 8 away from the arc-shaped bracket 1. Adjacent protrusions 9 form locking holes. One end of the mounting block 43 is fixedly connected to a slider 10. The slider 10 is slidably mounted on the arc-shaped slide rail 8. An elastic piece 11 is provided inside the slider 10. One end of the elastic piece 11 is elastically connected to the slider 10, and the other end extends to the outside of the slider 10. A locking block 12 is fixedly mounted in the middle of the elastic piece 11. The locking block 12 is locked in any locking hole.

[0038] The support block 13 is located on the inner side of the arc-shaped bracket 1. The side of the support block 13 away from the arc-shaped bracket 1 is curved, and a pad 14 is fixedly installed on the curved surface. The support block 13 and the pad 14 can improve the comfort of the patient when wearing the fixation device and reduce pressure on the head and other parts of the body. There are two pressure plates 15, which are detachably installed on the inner sides of both ends of the arc-shaped bracket 1. They can be replaced or adjusted as needed to better adapt to the head shape and fixation needs of different patients. Specifically, the inner sides of both ends of the arc-shaped bracket 1 are provided with insertion interfaces. One side of the pressure plate 15 is fixedly provided with a plug plate for insertion into the insertion interface. A baffle is fixedly connected to the side of the plug plate away from the pressure plate 15. The baffle, the plug plate, and the pressure plate 15 form an "I"-shaped structure, which is conducive to insertion into the insertion interface on the inner side of the arc-shaped bracket 1.

[0039] The specific usage process of this embodiment is as follows:

[0040] Insert the trachea into the installation tube 3 through the opening on the side of the installation tube 3;

[0041] Pull the flexible plate 41 so that it wraps around the air tube and is rolled up at the slot 7. Insert the end of the flexible plate 41 between the bottom of the mounting slot and the clamping plate 44 and continue to push it inward. The ratchet 42 and the pawl 45 will not obstruct the entry of the flexible plate 41. As the flexible plate 41 is rolled up, the air tube is initially fixed. When the flexible plate 41 is rolled up to the appropriate degree, under the pushing force of the thrust spring 46, the pawl 45 on the clamping plate 44 and the ratchet 42 on the flexible plate 41 engage in one direction to achieve a firm lock on the air tube.

[0042] Rotate the rotating ring 5 so that the opening of the rotating ring 5 is away from the opening of the mounting tube 3 and is located on the side of the mounting tube 3 away from the opening. Make the patient's mouth contact the beeswax layer on the rotating ring 5. The rotating ring 5 can rotate in the annular groove 6 according to the movement of the patient's mouth, reducing friction and discomfort to the patient's mouth.

[0043] The fixation device is worn on the patient's head via the strap 2. The Velcro 16 at the ends of the strap 2 is used to attach the two pads 14 to the patient's face, and the pad 14 under the support block 13 abuts against the palate. The tightness of the strap 2 is then adjusted to suit the patient's comfort and fixation requirements.

[0044] When oral care is required for the patient, the elastic plate 11 is pressed up, and the elastic plate 11 drives the locking block 12 to disengage from the locking hole. The slider 10 moves on the arc-shaped slide rail 8 to adjust the angle of the installation tube 3. When the appropriate angle is adjusted, the locking block 12 on the elastic plate 11 inside the slider 10 engages in the corresponding locking hole, fixing the angle of the installation tube 3. This creates space for the oral care device to be moved, avoiding the need to disassemble the trachea and fixation device, saving time and effort, and making the operation convenient.

[0045] When the air tube needs to be removed, simply loosen the Velcro 16, press down the end of the clamping plate 44 away from the clamping claw 45, pull out the flexible plate 41, then rotate the swivel 5 until the opening coincides with the opening of the installation tube 3, and then remove the air tube from the installation tube 3 to complete the removal. It is simple and convenient.
