[0002] Common endotracheal tube fixing devices mostly realize the lateral movement of the endotracheal tube by slidingly connecting a slider with a fixing frame body. The fixing frame body is mostly made of elastic material, and face fixing stickers are arranged through wing plates on both sides of the fixing frame body, and elastic bandages are externally connected to the wing plates through connecting parts, such as a endotracheal tube holder disclosed in CN 219921777U; or a buckle with adjustable length is connected to connect the neck or head strap to achieve adjustable adaptation to the patient's head circumference, such as a endotracheal tube fixer disclosed in CN 219208545U; the face fixing sticker, the fixing frame body, and the neck or head strap are used together to fix the patient's face and head.

[0003] The wing plate in the above device lacks angle adjustment for the patient's face, or the angle adjustment is limited, and it is difficult to fit closely to patients with different face shapes; at the same time, due to the frequent use of the external length adjustment part, the connecting part connected thereto is easily deformed or damaged by force, which then causes the integrally connected wing plate to bend, affecting the close fit of the wing plate and its facial fixing patch to the face.

[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below in combination with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Combined with the embodiments and Figure 1-7 The fixing frame body for endotracheal intubation includes an arc-shaped bracket 11 and two wing plates. The arc-shaped bracket 11 and the wing plates are connected as one piece. Both sides of the arc-shaped bracket 11 are connected to the wing plates through a bending portion. The wing plate includes a connecting portion 22 and a fixing portion 21 connected as one piece. The bending portion is connected to the fixing portion 21. The connecting portion 22 is provided with a connecting hole for an external length adjusting member 5. A bending notch 23 is provided at the junction of the fixing portion 21 and the connecting portion 22, which is used to reduce the bending force required when the connecting portion 22 is bent relative to the fixing portion 21 and reduce the influence of the bending of the connecting portion 22 on the curvature of the fixing portion 21. The fixing frame body is made of elastic material. A lip fixing patch is connected to the back of the arc-shaped bracket, and a face fixing patch 7 is connected to the back of the fixing portion. The face fixing patch 7 is a hypoallergenic medical adhesive patch.

[0022] The bending portion includes a bending zone 33 and a transition zone which are connected in one piece. The arc bracket 11 and the fixing portion 21 are connected to each other via the transition zone on both sides of the bending zone 33. The thickness of the transition zone is greater than that of the bending zone 33 to strengthen the anti-cracking performance of the bending section and extend the use of the product.

[0023] The transition zone includes a first transition zone 31 connected to the arc-shaped bracket 11 and a second transition zone 32 connected to the fixing portion 21. A step with different thicknesses is left at the junction of the first transition zone 31 and the bending zone 33 to form a first step surface on the front or back side of the bending portion. The thickness of the second transition zone 32 decreases along the direction toward the bending zone 33 to form a second slope surface on the front or back side of the second transition zone 32.

[0024] Specifically, the first step surface and the second slope surface are both located on the front side or the back side of the bending portion, or the first step surface and the second slope surface are arranged opposite to each other on the front side or the back side of the bending portion.

[0025] The front of the fixed part 21 and the connecting part 22 is concave to form a bending recess 23, and a gap is left between the inner surface of the bending recess 23 and the back of the wing plate, and the inner wall corners of the bending recess 23 are all rounded; the top and bottom ends of the bending recess 23 respectively penetrate the upper end surface and the lower end surface of the wing plate, so that the connecting part is easy to bend relative to the fixed part, which is convenient for medical staff to load and unload and adjust the external length adjustment part, and at the same time reduces the influence of the connecting part on the curvature of the fixed part when it is tensilely deformed. The number of connecting parts on the wing plate can be one or more.

[0026] The front side of the arc-shaped bracket 11 is also provided with a slide groove assembly, which is slidably matched with the external slider 4 to drive the external slider 4 to move along the arc line of the arc-shaped bracket 11 in the horizontal direction.

[0027] The slide groove assembly includes a connecting strip 12 and an arc plate 13. The arc plate 13 and the arc bracket 11 are arranged parallel to each other. The arc plate 13 is fixed to the front side of the arc bracket 11 through the connecting strip 12, and the connecting strip 12 divides the space between the arc plate 13 and the arc bracket 11 into upper and lower slide grooves for the external slider 4 to slide. The arc plate 13, the connecting strip 12 and the arc bracket 11 form a sliding channel with an H-shaped cross-section, and the cross-section of the external slider 4 matches the H-shaped cross-section.

[0028] The left and right ends of the connecting strip 12 are provided with wedge blocks 121 for preventing the external slider 4 from slipping out from the end of the connecting strip 12. The asymmetric tip of the wedge block 121 is arranged near the end of the connecting strip 12 to achieve one-way abutment between the wedge block 121 and the external slider 4. The external slider 4 is made of elastic material. The opening of the external slider 4 enters through the asymmetric tip of the wedge block 121 at the end of the connecting strip 12, and slides into the sliding channel after being compressed and deformed. After entering the sliding channel, the widened end of the wedge block 12 abuts against the external slider 4, so as to limit the external slider 4 in the sliding channel and prevent it from slipping out.

[0029] Specifically, the minimum value of the outer diameter of the wedge block 121 is smaller than the inner diameter of the opening of the external sliding block 4 and smaller than the maximum value of the outer diameter of the wedge block 121 .

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
