[0017] Compared with the prior art, the beneficial effects of this application are:

[0018] This application provides an endotracheal tube fixation device. A fixing sleeve is used to secure the endotracheal tube. After intubation, the fixing sleeve is placed in the oral cavity, with a retaining strip positioned inside the teeth. The retaining strip is extended and supported between the maxilla and mandible inside the oral cavity. This fixes the endotracheal tube to the airway wall after the endotracheal tube cuff is inflated. The teeth block the retaining strip, preventing it from moving outwards. Simultaneously, a ring-shaped retaining part is positioned outside the mouth. The side, with its inner and outer barriers, prevents the endotracheal tube from dislodging outwards or advancing inwards. This eliminates the need for tape to secure the endotracheal tube, preventing accidental dislodgement during lip augmentation or rhinoplasty. The absence of tape also facilitates observation of the symmetry of the corners of the mouth and nostrils during cosmetic surgery, without obstructing the view. Furthermore, the fixation sleeve engages the patient's teeth in the second annular step groove, limiting tooth positioning and preventing the patient from biting down on the endotracheal tube during general anesthesia.

[0029] See attached document Figures 1 to 4As shown, this application embodiment provides an endotracheal tube fixation device. The fixation device 100 includes a fixing sleeve 2 and a limiting member. The fixing sleeve 2 is circumferentially provided with a plurality of movable clamping members 3. The clamping members 3 extend and retract radially along the fixing sleeve 2 to change the clamping space for the endotracheal tube 1. The outer peripheral wall of the fixing sleeve 2 is also provided with a first annular stepped groove 4 and an annular stop portion 12 located at one end of the first annular stepped groove 4. The limiting member includes an inner sleeve 5 and an outer sleeve 11. The inner sleeve 5 is disposed in the first annular stepped groove 4, and the outer sleeve 11 is sleeved on the inner sleeve 5. The outer peripheral wall of the outer sleeve 11 is flush with the outer peripheral wall of the fixing sleeve 2. The inner sleeve 5 is circumferentially arranged with a plurality of retractable baffles 8. During general anesthesia, the baffles 8 are located inside the teeth in the oral cavity and can extend out of the outer sleeve 11 to support the maxilla and mandible inside the oral cavity.

[0030] Specifically:

[0031] See Figures 1 to 4 As shown, the fixing sleeve 2 is a cylindrical tube structure. For ease of explanation, the end of the fixing sleeve 2 inserted into the oral cavity is defined as the first end, and the end of the fixing sleeve 2 exposed outside the oral cavity is defined as the second end. A first annular stepped groove 4 is provided on the outer peripheral sidewall of the fixing sleeve 2 near the first end. An inner sleeve 5 is provided in the first annular stepped groove 4. The inner sleeve 5 is an annular sleeve and is fitted in the first annular stepped groove 4. The inner sleeve 5 is interference-fitted with the fixing sleeve 2 so that the inner sleeve 5 can be fixed in the first annular stepped groove 4. The inner sleeve 5 has a hollow cavity. An inflatable bladder is attached to the bottom inner wall of the hollow cavity. The inflatable bladder can be inflated and expands towards the top of the inner sleeve 5. The outer wall of the inflatable bladder has a plurality of column sleeves 7 arranged circumferentially, which are attached to the inflatable bladder. A plurality of silicone strips 8 are inserted into the column sleeves 7 with an interference fit. The strips 8 are covered with a rigid internal support body, which can prevent the strips 8 from deforming, thereby providing good support and preventing them from falling off. The outer wall of the inner sleeve 5 has a plurality of first guide holes 9 arranged circumferentially, each corresponding to one of the strips 8. The strips 8 pass through the first guide holes 9 to the outside of the inner sleeve 5, and when the inflatable bladder inflates, the strips 8 can slide along the first guide holes 9.

[0032] Furthermore, the outer sleeve 11 is fitted onto the outer peripheral wall of the inner sleeve 5. The outer sleeve 11 includes a first sleeve portion 1101 and a second sleeve portion 1102. The first sleeve portion 1101 is provided with a plurality of second guide holes 10 circumferentially. The second guide holes 10 correspond one-to-one with the first guide holes 9. The stop strip 8 extends from the first guide hole 9 and extends into the second guide hole 10. When the inflatable bladder is in a deflated state, the end of the stop strip 8 is flush with the outer end of the second guide hole 10. When the inflatable bladder is inflated, the stop strip 8 extends outward from the second guide hole 10, thereby forming a barrier on the inside of the teeth and supporting the upper and lower jaws inside the oral cavity, thus fixing the sleeve 1 and preventing it from moving outside the oral cavity. The second sleeve portion 1102 is integrally formed on the outer end of the first sleeve portion 1101, and the outer peripheral wall of the second sleeve portion 1102 is provided with a second annular stepped groove 1103. As an explanation, during general anesthesia, when the fixation sleeve 2 is placed inside the mouth, the retainer 8 is located inside the teeth, and the teeth bite into the second annular stepped groove 1103 of the body 1102 of the second sleeve. By inflating the inflatable cuff, the cuff expands, pushing the retainer 8 out through the second guide hole 10. The retainer 8 is supported between the maxilla and mandible inside the mouth. The teeth block the retainer 8, preventing the fixation sleeve 2 from moving outward. At the same time, the annular retainer 12 is located outside the mouth, and the retainer 8 and the annular retainer 12, one inside and one outside, form a barrier, thus preventing the endotracheal tube 1 from falling outward or being pushed inward. The teeth biting into the second annular stepped groove 1103 can both limit the teeth and prevent the patient from biting off the endotracheal tube 1 during general anesthesia. When the patient wakes up and can breathe independently, the inflatable cuff is deflated. The inflatable cuff contracts and pulls the retainer 8 back, at which point the endotracheal tube 1 and the retaining sleeve 2 can be removed together. Furthermore, it is foreseeable that since the outer peripheral wall of the outer sleeve 11 is flush with the outer peripheral wall of the fixation sleeve 2, the entire fixation device can be removed without opening the patient's mouth during the removal of the fixation sleeve 2, which is very convenient.

[0033] In one embodiment, to facilitate the inflation and deflation of the inflatable bladder, see [reference needed]. Figure 3 As shown, a clearance groove 17 is provided in the first annular stepped groove 4 along the axial direction of the fixed sleeve 2. The inflatable bladder is provided with an inflation tube 18. The inflation tube 18 passes through the inner sleeve 5 and then through the clearance groove 17 into the inner side of the fixed sleeve 2, and extends along the inner wall of the fixed sleeve 2 to the outside of the fixed sleeve 2. An air valve 6 is provided at the end of the inflation tube 18. The air valve 6 is connected to the air filling bladder 19. Therefore, by setting the air valve 6, the air filling bladder 19, and the inflation tube 18, the inflation and deflation operations of the inflatable bladder can be realized.

[0034] In one embodiment, a third annular stepped groove 13 is provided at one end of the fixed sleeve 2 near the second end. The clamping member 3 includes a clamping plate 302 and a push rod 301. Six third guide holes 15 are arranged circumferentially inside the third annular stepped groove 13. A push rod 301 is provided in each alternate third guide hole 15. The outer diameter of the push rod 301 is smaller than the inner diameter of the third guide hole 15, so that the push rod 301 can move back and forth along the axial direction of the push rod 301. A clamping plate 302 is provided at the end of each push rod 301. A rotatable movable ring 14 is provided in the third annular stepped groove 13. Three adjusting members 16 corresponding to the extension and retraction of the clamping member 3 are provided on the inner side of the movable ring 14. When the three adjusting members 16 rotate to correspond to the third guide hole 15 where the push rod 301 is located, the adjusting members 16 push the clamping plate 302 outward.

[0035] Furthermore, in order to enable the adjusting member 16 to push out the push rod 301, the adjusting member 16 includes a spring and a round-headed pin. The inner wall of the movable ring 14 has three mounting holes arranged in a circumferential array. The spring is set in the mounting hole, and the round-headed pin is fixedly connected to the spring. It can be imagined that when the round-headed pin is squeezed, the round-headed pin will retract into the mounting hole and the spring will be compressed. When the pressure on the round-headed pin is removed, the spring will reset and push the round-headed pin out of the mounting hole.

[0036] Based on the structure of the adjusting member 16 and the clamping member 3, it can be understood that when the endotracheal tube is not clamped and fixed, the three adjusting members 16 are placed in the three third guide holes 15 without clamping members 3. When it is necessary to fix the endotracheal tube 1, the endotracheal tube 1 is passed through the middle of the fixed sleeve 2. When the movable ring 14 is rotated, the three adjusting members 16 will rotate with it. The round-headed pin is squeezed into the mounting hole by the third annular stepped groove 13. In this way, the round-headed pin will not obstruct the rotation of the movable ring 14. When the three movable pins rotate to the next third guide hole 15, the spring pushes the compressed round-headed pin into the third guide hole 15 where the clamping member 3 is located. Then the round-headed pin pushes the push rod 301 towards the center of the fixed sleeve 2, so that the clamping plate 302 is circumferentially retracted towards the fixed sleeve 2 and abuts against the outer wall of the endotracheal tube 1, thereby fixing the endotracheal tube 1 and preventing the endotracheal tube 1 from moving.

[0037] Furthermore, in order to ensure that the clamp 302 fits well against the endotracheal tube 1, in one embodiment, the clamp 302 is an arc-shaped clamp 302. The arc surface of the arc-shaped clamp 302 fits against the outer wall of the endotracheal tube 1 to increase the contact area and facilitate clamping the clamp 302. Of course, in order to ensure the clamping firmness of the clamp 302 against the endotracheal tube 1, several creases can be provided on the side of the clamp 302 that fits against the endotracheal tube 1 to increase the friction between the clamp 302 and the endotracheal tube 1, thereby clamping the endotracheal tube 1 more firmly.

[0038] Of course, in order to prevent the push rod 301 from falling off the third guide hole 15, in one embodiment, the third guide hole 15 is a stepped hole, the end of the third guide hole 15 away from the clamping plate 302 is a large diameter section, and the end of the third guide hole 15 close to the clamping plate 302 is a small diameter section. An anti-detachment block is provided at the end of the push rod 301 located at the large diameter section. The diameter of the anti-detachment block is larger than the diameter of the small diameter section. Thus, it can be imagined that, based on the anti-detachment block, the push rod 301 cannot fall off from the small diameter section end, and based on the clamping plate 302, the push rod 301 cannot fall off from the large diameter section end.

[0039] In summary, the method of use and working principle of the endotracheal tube fixation device provided in this application embodiment are as follows:

[0040] First, pass the endotracheal tube 1 through the fixing sleeve 2;

[0041] Next, complete the intubation of endotracheal tube 1, and inflate the cuff of endotracheal tube 1 to fit tightly against the airway wall, so that endotracheal tube 1 is fixed to the airway wall.

[0042] Then move the fixed sleeve 2 so that the teeth bite into the second annular step groove 1103 of the second sleeve body 1102, so as to prevent the patient from biting down on the endotracheal tube 1 during the entire general anesthesia operation. Then rotate the movable ring 14 so that the adjusting member 16 corresponds to the third guide hole 15 where the clamping member 3 is located. The round pin is pushed into the third guide hole 15 where the clamping member 3 is located under the action of the spring, thereby pushing the push rod 301 to pull the clamping plate 302 towards the center of the fixed sleeve 2, so that the clamping plate 302 abuts against the endotracheal tube 1, thereby fixing the endotracheal tube 1 in the fixed sleeve 2.

[0043] Next, by squeezing the airbag 19, the inflatable airbag is inflated. After the inflatable airbag expands, it pushes the stop bar 8 outward, so that the stop bar 8 extends and is located inside the teeth, and is supported between the maxilla and mandible inside the oral cavity. It is limited by the forward and backward movement of the ring stop part 12 and the fixing sleeve 2. The fixing sleeve 2 cannot move, so the endotracheal tube 1 also cannot move, preventing the endotracheal tube 1 from falling out due to accidental contact during the operation, thereby supplying oxygen to the patient during the general anesthesia operation and preventing the patient from hypoxia.

[0044] After the surgery is completed and the patient is awake and able to breathe independently, the gas in the inflatable cuff is released through the air valve 6, the inflatable cuff contracts, the stop bar is retracted, and the endotracheal tube 1 and the fixing sleeve 2 can be removed together.

[0045] In summary, the endotracheal tube fixing device provided in this application embodiment uses a fixing sleeve 2 with a clamping member 3 that is radially adjustable along the fixing sleeve 2 to fix the endotracheal tube 1. After the endotracheal tube 1 is intubated, the fixing sleeve 2 is placed in the oral cavity, with the retaining strip 8 positioned inside the teeth. After the inflatable cuff is inflated, the retaining strip 8 extends and supports the upper and lower jaws inside the oral cavity. Thus, after the cuff of the endotracheal tube 1 is inflated, the endotracheal tube 1 is fixed to the airway wall. The retaining strip 8, after extending and being positioned inside the teeth, supports the upper and lower jaws inside the oral cavity. The teeth block the retaining strip 8, thus fixing the endotracheal tube 1. 2. It will not move outward. At the same time, the ring stop 12 is located on the outside of the mouth. The stop strip 8 and the ring stop 12 form an obstruction, one inside and one outside. Therefore, the endotracheal tube 1 will not be dislodged or pushed inward due to accidental touching or pulling by the doctor during rhinoplasty and lip shaping surgery. Thus, it is not necessary to use tape to fix the endotracheal tube 1 to prevent it from falling off. It is convenient to observe whether the corners of the mouth and nostrils are symmetrical during cosmetic surgery. It will not obstruct the view during the operation. In addition, during the fixation process of the fixing sleeve 2, the patient's teeth bite into the second annular step groove 1103. While limiting the teeth, it can prevent the patient from biting off the endotracheal tube 1 during general anesthesia.

[0046] The above description is only a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
