Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to an anti-lip-biting endotracheal intubation fixator. Background Technology
[0002] Currently, when patients use intubation fixation devices in clinical practice, their teeth often shift between themselves and the fixation device when they are agitated or uncomfortable. When the teeth shift, they come into contact with the endotracheal tube, and the patient will subconsciously bite the endotracheal tube out of shape, which often requires the endotracheal tube to be replaced. Replacing the tube frequently increases the risk of lung infection for the patient.
[0003] Many departments choose the 3M tape + syringe core method, but there is a risk that if the patient's bite is not tight or the syringe is bitten flat, the cannula may be deformed, which may lead to suffocation and other dangers for the patient. Utility Model Content
[0004] This utility model provides an anti-lip-biting endotracheal tube fixation device, which solves the above-mentioned technical problems.

[0053] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0054] Please see Figures 1 to 4 As shown, the embodiments provided by this utility model are as follows:
[0055] Example 1
[0056] The anti-lip-biting endotracheal intubation fixator includes an inlet end 1, a tube body 2, an intubation end 4, and a limiting plate 7. The tube body 2 has an inlet end 1 and an intubation end 4 at its two ends. A groove 5 is provided at the inlet end 1. The tube body 2 is positioned by conforming to the patient's tongue through the groove 5, ensuring the endotracheal tube is in the correct position. The shape of the tongue affects the position of the endotracheal tube; conforming to the tongue effectively restricts the tube's position, reducing the possibility of deviation or inaccurate intubation. The conformation of the groove 5 to the tongue enhances the stability of the endotracheal tube. The tongue, as a natural limiter for the intubation, provides stable support, preventing movement or shaking of the tube within the oral cavity, reducing the risk of dislodgement. Inaccurate or unstable intubation can lead to intubation-related complications such as aspiration and airway obstruction. The conformation of the groove 5 to the tongue reduces the occurrence of these complications, improving the safety and success rate of intubation treatment. Correct intubation position reduces patient discomfort. Fixing the endotracheal tube in the correct position not only reduces irritation to the oral mucosa and larynx but also improves patient comfort, increasing treatment acceptance and compliance. The groove 5, which conforms to the tongue for positioning, simplifies the intubation process. Caregivers can more easily confirm the tube's position and make timely adjustments, reducing operational complexity and improving the efficiency and quality of care. The outer side of the tube body 2 is equipped with wing plates 3, symmetrically distributed. These symmetrically distributed wing plates 3 provide uniform support, enhancing the overall stability of the endotracheal tube fixator. This symmetrical distribution ensures equal support on both sides of the tube, reducing wobbling and displacement, and helping to maintain the tube in the correct position. The symmetrically distributed wing plates 3 evenly distribute the pressure on the tube, reducing the risk of damage to the patient's oral mucosa from local pressure points. This design reduces friction and pressure between the tube and oral tissues, improving patient comfort and safety. Because the wing plates 3 are symmetrically distributed on the outer side of the tube body 2, the fixator is suitable for patients with different oral structures and tube sizes. Regardless of the patient's oral cavity shape, the symmetrically distributed wing plates 3 provide uniform support, ensuring effective fixation of the endotracheal tube and increasing the applicability and versatility of the fixator. The symmetrically distributed wing plates 3 help balance the forces acting on the endotracheal tube, reducing twisting or displacement caused by uneven force. This design enhances the overall stability and safety of the fixator, reducing the risk of tube dislodgement. The symmetrically distributed wing plate 3 design reduces friction and discomfort between the endotracheal tube and oral tissues, improving patient comfort. The comfort of the endotracheal tube fixator is a crucial factor in patient acceptance of treatment; the symmetrically distributed wing plate 3 design helps improve treatment acceptance and compliance. The tube body 2 contains a limiting plate 7 located inside, near the end of the endotracheal tube 4. The symmetrical distribution of the limiting plates 7 within the tube body 2 provides uniform support, effectively enhancing the stability of the endotracheal tube.By supporting both sides of the intubation tube, wobbling and displacement are reduced, ensuring the tube is in the correct position and lowering the risk of dislodgement. The symmetrical distribution of the limiting plates 7 evenly distributes the pressure on the intubation tube. This helps reduce friction and pressure between the intubation tube and the inner wall of the tube body 2, lowering the risk of local tissue damage and improving patient comfort and safety. The symmetrical distribution of the limiting plates 7 helps ensure a more precise and stable position of the intubation tube within the tube body 2. This is particularly important for treatment scenarios requiring accurate positioning, such as patients requiring regular airway pressure monitoring or respiratory support. Due to the symmetrical distribution of the limiting plates 7 within the tube body 2, the fixator is suitable for patients with different oral structures and intubation tube sizes. Regardless of the patient's oral cavity morphology, the symmetrical distribution of the limiting plates 7 provides stable support, ensuring effective fixation of the intubation tube, increasing the applicability and versatility of the fixator. The symmetrically distributed limiting plates 7 evenly distribute the forces on the intubation tube, improving the overall stability and safety of the fixator. This helps reduce the occurrence of intubation-related complications, improves the success rate and safety of treatment. The limiting plate 7 has slots 6 that pass through it. After the endotracheal tube 2 passes through, it is fixed by the slots 6 of the limiting plate 7, preventing slippage and accidental dislodgement. It also prevents teeth from directly contacting the endotracheal tube, thus protecting it. The slots 6 are evenly distributed on the limiting plate 7, ensuring the stability of the endotracheal tube within the fixator. The evenly distributed slots 6 provide more uniform support, preventing instability or slippage caused by concentrated force at a single point. By evenly distributing the slots 6 throughout the limiting plate 7, the pressure and burden on the endotracheal tube are evenly distributed. This helps reduce discomfort or injury caused by excessive local pressure, improving patient comfort and safety. The evenly distributed slots 6 provide more secure fixation of the endotracheal tube within the fixator. Whether during normal physiological movement or abnormal activity, the evenly distributed slots 6 provide uniform support, effectively preventing tube displacement or dislodgement. Because the slots 6 are evenly distributed, the contact area between the cannula and the limiting plate 7 is increased, and the pressure is dispersed, reducing local pressure and the risk of skin or mucous membrane pressure, thus helping to reduce the occurrence of cannula-related complications. The evenly distributed slots 6 make the fixator suitable for patients with different oral anatomy. Regardless of the shape of the oral cavity, the even distribution of slots 6 can provide stable support, ensuring effective fixation of the cannula, increasing the applicability and versatility of the fixator. The entire structure is small in size, provides high patient comfort, minimizes damage, is convenient for nurses to operate, and is simple to change, with a low risk of cannula dislodgement.
[0057] When using the anti-lip-biting endotracheal tube fixator based on Example 1:
[0058] Medical staff first select an appropriate size endotracheal tube based on the patient's condition.
[0059] During intubation, medical staff gradually insert the endotracheal tube through the patient's mouth and pharynx into the trachea until the tube is in place.
[0060] After the intubation is in place, the medical staff ensures that the tube is in the correct position. They first put the anti-lip endotracheal tube fixator into the endotracheal tube and then further embed it into the patient's mouth to ensure the stability and safety of the intubation.
[0061] The tube body 2 of the anti-lip-biting endotracheal intubation fixation device is positioned by fitting the patient's tongue with the groove 5, ensuring accurate and stable intubation. The tube body 2 of the anti-lip-biting endotracheal intubation fixation device is provided with grooves 5, which can fit with the patient's tongue, providing stable support and positioning, and ensuring accurate intubation.
[0062] Meanwhile, the limiting plate 7 of the fixator is symmetrically distributed inside the tube body 2, providing uniform support force and enhancing the stability of the intubation. The inside of the fixator is equipped with a limiting plate 7, on which slots 6 are evenly distributed. After the endotracheal tube passes through the slots 6, it is fixed by the limiting plate 7, ensuring that the position of the tube will not change, dispersing the force on the tube, and enhancing the stability and safety of the intubation.
[0063] The wing plates 3 are symmetrically distributed on the outside of the tube body 2, providing additional support and stability to prevent displacement or twisting of the insertion tube. The two sides of the retainer are respectively provided with symmetrically distributed wing plates 3. These wing plates 3 can provide additional support force, enhance the stability of the insertion tube, prevent its displacement or fall off, and prevent displacement or twisting of the insertion tube.
[0064] The evenly distributed slots 6 on the limiting plate 7 ensure that the endotracheal tube can be firmly fixed after passing through the fixator, reducing the risk of tube dislodgement.
[0065] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model.
