[0029] like Figures 1-5 As shown, the endotracheal tube fixation device in this embodiment includes a fixation frame 100. The inner side of the fixation frame 100 is arched and matches the human face, conforming to the physiological curvature of the human face. The fixation frame 100 is provided with matching headbands 110 on both sides. By wrapping the two headbands 110 around the back of the patient's head and connecting the headbands 110, the fixation frame 100 can be fixed at the oral cavity position of the patient's face.

[0030] The fixing frame 100 has an opening 101 that exposes the entire lip. A movable dental pad 120 is provided in the opening 101. One end of the dental pad 120 extends into the oral cavity and the other end extends out of the oral cavity. An arc-shaped groove 201 is provided on the side wall of the dental pad 120 along its extension direction. A detachable strap 130 is provided on the side wall of the dental pad 120 outside the oral cavity. The strap 130 is used to fix the endotracheal tube in the arc-shaped groove 201.

[0031] In this embodiment, the opening 101 is used to form a large hollow area in the middle of the fixation frame 100 so that the endotracheal tube can be extended through the opening 101. At the same time, it can provide enough space for medical staff to perform oral care.

[0032] The design incorporates a bite pad 120, an arc-shaped groove 201, and a strap 130. In practical use, the strap 130 secures the endotracheal tube within the arc-shaped groove 201, thus fixing the endotracheal tube to the bite pad 120. When the bite pad 120 is in a fixed position, the endotracheal tube is secured. Specifically, the detachable strap 130 facilitates the assembly and disassembly of the bite pad 120 and the endotracheal tube, making it convenient for practical use.

[0033] The movable design of the bite pad 120 allows for the fixation of the endotracheal tube at different positions when it passes through the opening 101 during actual use. This improves the applicability of the fixation device.

[0034] Combination Figure 3 and Figure 4 As shown, in this embodiment, the fixing frame 100 protrudes outward on the side away from the face to form a protrusion body 102 located on the upper and lower sides of the opening 101. The protrusion body 102 is arranged along the extension direction of the fixing frame 100. The opposite side of the protrusion body 102 is provided with a sliding groove 401. The sliding groove 401 is arranged along the extension direction of the protrusion body 102. The side of the protrusion body 102 away from the fixing frame 100 is provided with a strip groove 103 that connects to the corresponding sliding groove 401.

[0035] The outer wall of the dental pad 120 is provided with a slider part 301 that extends into the corresponding slide groove 401 and slides. The slider part 301 is provided with a threaded rod 302 that extends through the strip groove 103. A locking block 310 is threadedly connected to the extended end of the threaded rod 302.

[0036] In this embodiment, the upper and lower sides of the dental pad 120 are slidably installed in the corresponding grooves 401 via the slider part 301, thereby enabling the dental pad 120 to be slidably installed in the opening 101 relatively stably. In actual use, by twisting the locking block 310 to press the side wall of the protrusion body 102, the slider part 301 can be fixed, that is, the dental pad 120 is fixed. By loosening the locking block 310 to move it away from the side wall of the protrusion body 102, the fixing of the slider part 301 is released, that is, the dental pad 120 can move in the opening 101. The operation is simple and convenient, which is beneficial to actual use.

[0037] Specifically, the fixing bracket 100 is made of plastic, giving it a certain degree of deformation capability so that it can be fixed to different face shapes by the headband 110; the mouthguard 120, the slider part 301, the threaded rod 302 and the locking block 310 are also made of plastic, so that the locking block 310 can press against the side wall of the protrusion body 102 to make the mouthguard 120 more secure.

[0038] In order to improve the comfort of wearing the bracket 100, ventilation holes 105 are provided on both sides of the opening 101 of the bracket 100.

[0039] In this embodiment, one end of the strap 130 is rotatably connected to the outer wall of the mouthguard 120. A fixing block 320 is provided on the side wall of the mouthguard 120 away from the arc groove 201. The fixing block 320 is integrally formed on the outer wall of the mouthguard 120. A through groove 321 is provided on the fixing block 320. The other end of the strap 130 extends into the through groove 321 through the arc groove 201. A locking rod 330 is threadedly connected to the fixing block 320. The locking rod 330 extends into the through groove 321 to compress the strap 130 to fix the strap 130.

[0040] In actual use, the mouthguard 120 has an installation groove 303 on its outer side wall. The installation groove 303 is located on the side near the arc groove 201. A binding rod is located in the middle of the installation groove 303. One end of the binding strap 130 is provided with a connecting ring that fits onto the binding rod. Thus, the rotatable connection of one end of the binding strap 130 on the outer side wall of the mouthguard 120 is preferably achieved.

[0041] In this embodiment, the fixing block 320 has a threaded hole on the side away from the dental pad 120 that connects to the through groove 321. The locking rod 330 is threaded into the threaded hole. Thus, when the endotracheal tube is located in the arc groove 201, the other end of the strap 130 is rotated by rotating one end of the strap 130 so that it passes around the endotracheal tube and extends out of the through groove 321. At this time, the strap 130 can be tightened by pulling the other end of the strap 130 to fix the endotracheal tube in the arc groove 201. At this time, the strap 130 is squeezed and fixed by twisting the locking rod 330 into the through groove 321. When it is necessary to remove the endotracheal tube in the arc groove 201, the strap 130 can be released by twisting the locking rod 330 back into the threaded hole. The strap 130 can be loosened to remove and install the endotracheal tube from the dental pad 120.

[0042] Specifically, in order to improve the effect of locking rod 330 in fixing strap 130, a rubber pad is provided at the end of locking rod 330 that extends into through groove 321. The rubber pad can increase the friction between the strap 130 by squeezing the strap 130, thereby improving the effect of fixing strap 130.

[0043] In this embodiment, the two sides of the fixation frame 100 extend outward to form fixing parts 104. The fixing parts 104 are provided with slots. One end of the headband 110 is rotatably connected to the slot, and the other end is detachably connected by Velcro. In use, the two headbands 110 are wrapped around the patient's head and connected by Velcro, thereby fixing the endotracheal tube fixation device to the oral cavity position on the patient's face.

[0044] In use, the present invention is first applied to the patient's face at the position of the mouth, so that the endotracheal tube extends out from the opening 101. Then, the two headbands 110 are wrapped around the back of the patient's head and connected to fix the fixation frame 100. Next, the mouthguard 120 is moved so that the side wall of the endotracheal tube fits into the arc groove 201. Then, the other end of the strap 130 is wrapped around the endotracheal tube and inserted into the through groove 321. The other end of the strap 130 is pulled to tighten the strap 130. The strap 130 is fixed by turning the locking rod 330. Finally, the mouthguard 120 is fixed by turning the locking block 310 to squeeze the side wall of the protrusion body 102.

[0045] In summary, the above description is only a preferred embodiment of the present utility model. All equivalent changes and modifications made within the scope of the patent application of the present utility model shall fall within the scope of the patent of the present utility model.
