[0018] The embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0019] This application provides an auxiliary fixing device for endotracheal intubation. By adjusting the fastening relationship between the threaded push rod and the slide rail structure, the position of the movable support can be moved left and right. After it is moved into place, the threaded push rod is tightened to fix the position of the movable support on the slide rail structure. Then, endotracheal intubation is performed through the movable support. It has the advantages of simple structure, convenient operation, and low cost.

[0020] To achieve the aforementioned technical effects, the overall concept of this application is as follows: An auxiliary fixation device for endotracheal intubation, the device comprising: The fixed bracket 1 is an arc-shaped long strip structure. A slide rail structure 10 is provided on the outer surface of the fixed bracket 1.

The tubular fixing member 22 has a U-shaped tube structure, and the length direction of the tubular fixing member 22 is parallel to the length direction of the first threaded through hole 21. A threaded push rod 3 is disposed in the first threaded through hole 21. The threaded push rod 3 is configured to be screwed into or out of the first threaded through hole 21 through a threaded structure, such that one end of the threaded push rod 3 near the slide rail structure 10 abuts against or is spaced from the slide rail structure 10. The nylon fastener 4 is provided on the slider 20, and the nylon fastener 4 is located on the side of the slider 20 opposite to the tubular fastener 22; The sponge pad 5 is disposed in the middle of the inner side of the fixed bracket 1; A pair of bracket plate structures 6 are provided at both ends of the fixed bracket 1, and each bracket plate structure 6 has a silicone adhesive 60 on its inner side. The headband 7 has two ends that are detachably connected to the two bracket plate structures 6.

[0021] The embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0022] See Figures 1-6 As shown, this application provides an auxiliary fixation device for endotracheal intubation, the device comprising: The fixed bracket 1 is an arc-shaped long strip structure. A slide rail structure 10 is provided on the outer surface of the fixed bracket 1. The slide rail structure 10 is also an arc-shaped long strip structure, and the inner side of the slide rail structure 10 is in close contact with the outer side of the fixed bracket 1. The movable support 2 includes: A sliding member 20 is slidably disposed on the slide rail structure 10. The sliding member 20 is provided with a first threaded through hole 21, which is directly opposite to the slide rail structure 10. A tubular fixing member 22 is provided at the bottom of the sliding member 20. The tubular fixing member 22 has a U-shaped tube structure, and the length direction of the tubular fixing member 22 is parallel to the length direction of the first threaded through hole 21. A threaded push rod 3 is disposed in the first threaded through hole 21. The threaded push rod 3 is configured to be screwed into or out of the first threaded through hole 21 through a threaded structure, such that one end of the threaded push rod 3 near the slide rail structure 10 abuts against or is spaced from the slide rail structure 10. The nylon fastener 4 is provided on the slider 20, and the nylon fastener 4 is located on the side of the slider 20 opposite to the tubular fastener 22; The sponge pad 5 is disposed in the middle of the inner side of the fixed bracket 1; A pair of bracket plate structures 6 are provided at both ends of the fixed bracket 1, and each bracket plate structure 6 has a silicone adhesive 60 on its inner side. The headband 7 has two ends that are detachably connected to the two bracket plate structures 6.

[0023] It should be noted that the Velcro fastener 4 is equipped with Velcro. When assisting in tube insertion, the Velcro fastener 4 can form a circular fixing space, which, together with the tubular fastener 22, can assist in fixing the tube. The sponge pad 5 is fixed to the fixed bracket 1 and is positioned facing the patient's face. The sponge pad 5 is used to contact the area above the patient's philtrum to provide comfort and prevent pressure sores from forming due to prolonged use of the mouthpiece.

[0024] Furthermore, when the threaded push rod 3 is screwed into the first threaded through hole 21 to the limit, the threaded push rod 3 presses the slide rail structure 10 and the sliding member 20 together, thereby fixing the position of the sliding member 20 on the slide rail structure 10. When it is necessary to adjust the position of the slider 20 on the slide rail structure 10, the threaded push rod 3 is screwed out of the first threaded through hole 21, thereby removing it from the extreme state when it was previously screwed in. The slide rail structure 10 and the slider 20 are separated, thereby adjusting the position of the slider 20 on the slide rail structure 10.

[0025] Since the tubular fixing member 22 has a U-shaped tube structure, its internal groove can be called the tubular groove F, which is used to fix the endotracheal tube during intubation.

[0026] In this embodiment, the position of the movable bracket can be moved left and right by adjusting the fastening relationship between the threaded push rod and the slide rail structure. After it is moved into place, the threaded push rod is tightened to fix the position of the movable bracket on the slide rail structure. Then, the endotracheal intubation is performed through the movable bracket. It has the advantages of simple structure, convenient operation and low cost.

[0027] When installing the endotracheal tube, place part of the endotracheal tube into the tubular groove F of the tubular fastener 22, wrap the nylon fastener 4 around the endotracheal tube, and fix the endotracheal tube by relying on the Velcro and the rough surface to bond it. Then, one end of the threaded push rod 3 is inserted into and rotated through the first threaded through hole 21 of the sliding member 20 on the movable bracket 2, so that the threaded push rod 3 contacts the surface of the fixed bracket 1 and forms a force that pushes the threaded push rod 3 forward toward the surface of the fixed bracket 1, thereby fixing the movable bracket 2. Rotate the threaded push rod 3 in the opposite direction again to disengage it from the surface of the fixed bracket 1, allowing the movable bracket 2 to move. When the nursing staff needs to clear sputum from the patient's mouth, they can manually release the threaded push rod 3 from the surface of the fixed bracket 1, allowing the movable bracket 2 to move left or right. After it is in place, tighten the threaded push rod 3 again to restrict the sliding part 20 of the movable bracket 2 to the position of the slide rail structure 10 of the fixed bracket 1, thus completing the movement of the endotracheal tube.

[0028] Furthermore, the cross-section of the tubular fastener 22 is an arc shape.

[0029] Furthermore, the bracket plate structure 6 is provided with a headband connection hole 61; Both ends of the headband 7 are detachably connected to the headband connection holes 61 of the two bracket plate structures 6.

[0030] In specific operation, the headband 7 passes through the headband connection holes 61 on the left and right sides of the bracket plate structure 6; and is then fixed by sewing. The headbands 7 on both sides are wrapped around the patient's head and glued in place, thereby helping to fix the endotracheal intubation fixator.

[0031] Furthermore, the slide rail structure 10 includes: The slide rail base plate 100 is closely attached to the outer side of the fixed bracket 1; Upper slide rail upright plate 101 is disposed on the upper edge of the slide rail base plate 100; The slide rail upright plate 102 is disposed at the lower edge of the slide rail base plate 100; The upper slide rail upright plate 101 is parallel to the lower slide rail upright plate 102, and both are perpendicular to the slide rail base plate 100, and both are located on the side of the fixed bracket 1 away from the fixed bracket 1. An upper slide rail baffle 103 is provided on the side of the upper slide rail upright plate 101 opposite to the slide rail bottom plate 100. The upper slide rail baffle 103 is located on the surface of the upper slide rail upright plate 101 opposite to the lower slide rail upright plate 102. A lower slide rail baffle 104 is provided on the side of the lower slide rail upright plate 102 away from the slide rail bottom plate 100. The lower slide rail baffle 104 is located on the surface of the lower slide rail upright plate 102 away from the upper slide rail upright plate 101. The slide rail base plate 100, the upper slide rail upright plate 101 and the lower slide rail upright plate 102 form a push rod fastening cavity A for the threaded push rod 3 to be screwed in or out; The upper slide rail upright plate 101, the upper slide rail baffle 103, and the slide rail bottom plate 100 form the upper slide rail limiting cavity B; The lower slide rail upright plate 102, the lower slide rail baffle 104, and the slide rail base plate 100 form the lower slide rail limiting cavity C.

A lower sliding member baffle 204 is provided on the side of the lower sliding member upright plate 202 away from the slide rail base plate 100. The lower sliding member baffle 204 is located on the surface of the lower sliding member upright plate 202 facing the upper sliding member upright plate 201. The upper sliding member upright plate 201, the upper sliding member baffle 203, and the sliding member main plate 200 form the upper sliding member limiting cavity D; The lower sliding member upright plate 202, the lower sliding member baffle 204, and the sliding member main plate 200 form the lower sliding member limiting cavity E; The upper sliding member upright plate 201 is located inside the upper slide rail limiting cavity B; The lower sliding member upright plate 202 is located inside the lower sliding rail limiting cavity C; The upper slide rail upright plate 101 is located inside the upper sliding member limiting cavity D; The lower slide rail plate 102 is located within the lower sliding member limiting cavity E.

[0033] It should be noted that the tubular fixing member 22 is located below the lower sliding member baffle 204, specifically in the following orientation: The tubular fixing member 22 and the lower sliding member limiting cavity E are located on both sides of a set of symmetrical planes of the lower sliding member baffle 204.

[0036] In summary, this endotracheal tube fixator solves the problem of existing technologies where the position of the endotracheal tube cannot be adjusted after it has been fixed. Furthermore, because the position of the endotracheal tube can be moved left or right as needed, it allows for cleaning of sputum from multiple locations, maintaining hygiene, and expanding the cleanable area when clearing sputum from the patient's mouth.
