Description

Technical Field

[0001] The utility model belongs to the technical field of oropharyngeal airways, and particularly relates to an oropharyngeal airway with a self-adaptive front-section curvature adjustment. Background Art

[0002] Oropharyngeal airways are suitable for perioperative or comatose patients who need a long time to relieve tongue retraction or whose upper airway obstruction cannot be relieved by mandibular support. The airway separates the root of the tongue from the posterior wall of the pharynx, thereby restoring the patency of the upper airway. However, the existing oropharyngeal airways are prone to movement, tilting, or even falling off during actual use, and have low safety of use. The current improved oropharyngeal airway includes a airway with a fixing plate at the bottom, and a ring-shaped positioning device is provided on the fixing plate so that it can be stably placed in the patient's mouth. The disadvantage is that the airway needs to be inserted first, and then a ring-shaped closed linear fixation is formed outside the patient's mouth and neck. There is also a method in which a corrugated bite pattern is provided on the outer surface of the annular structure of the oropharyngeal airway so that the corrugated bite pattern can achieve the purpose of fixation and anti-slip. However, none of the above-mentioned improved oropharyngeal airways can solve the fundamental reason why the oropharyngeal airway is easily dislocated. The fundamental reason for the dislocation of the oropharyngeal airway is that the overall curvature of the airway is inconsistent with the physiological curvature of the human pharynx, causing the front section of the airway to contact the patient's palate, thereby causing the airway to become unstable and dislocate. Utility Model Content

[0003] The utility model aims to provide an oropharyngeal airway with a front-section curvature self-adaptive adjustment, the plasticity of the curvature of the oropharyngeal airway makes it more closely fit the physiological curvature of the patient's upper jaw, and the downward pressure of the tongue can make the position of the airway in the pharyngeal cavity more fixed and not easy to fall out.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a front-section curvature adaptive adjustable oropharyngeal airway, including an oropharyngeal airway body, wherein a groove is provided on the side where the oropharyngeal airway body fits with the upper jaw. The groove can reduce the friction force on the pharyngeal cavity during the insertion of the oropharyngeal airway, thereby reducing the damage to the pharyngeal cavity, and the insertion is smoother. Moreover, since the groove is provided on the oropharyngeal airway body, the oropharyngeal airway can be adapted to the different lengths and different physiological curvatures of the upper jaw and automatically lift up to the tongue side, so that no contact force is generated to cause accidents. Due to the downward pressure of the tongue body, the position of the oropharyngeal airway is more stable and not easy to move.

[0005] The technical solution further improved in the above technical solution is as follows:

[0006] 1. In the above solution, the main body of the oropharyngeal airway is a hollow arc-shaped structure. The groove divides the main body of the oropharyngeal airway into three parts, including a first airway, a second airway, and a bent portion connecting the first airway and the second airway. The first airway and the second airway are bent through the bent portion.

[0007] 2. In the above solution, the main body of the oropharyngeal airway is an integrally formed structure, and a groove is provided on this structure.

[0008] 3. In the above solution, the main body of the oropharyngeal airway is a split structure, and the first airway and the second airway are connected together through a bent portion.

[0009] 4. In the above solution, the length of the second airway accounts for 1 / 4 to 1 / 3 of the length of the entire main body of the oropharyngeal airway.

[0010] 5. In the above solution, a first anti-scratch portion and a second anti-scratch portion are provided on the sides of the first airway and the second airway close to the groove.

[0011] 6. In the above solution, a guiding section is provided at one end of the second airway away from the groove. The guiding section extends towards the arc center side of the second airway, and a third anti-scratch portion is provided on the side of the guiding section away from the arc center.

[0012] 7. In the above solution, a mouthguard portion is connected to one end of the first airway away from the groove. When the oropharyngeal airway is used, the mouthguard portion is placed in the oral cavity, and the second airway extends deep into the throat. A retaining piece is provided at one end of the mouthguard portion away from the main body of the oropharyngeal airway. The retaining piece can fix the oropharyngeal airway in the mouth and also prevent the oropharyngeal airway from slipping deep into the throat.

[0013] 8. In the above solution, the bent portion is made of a material with toughness and not easily broken, and having a certain folding arc. Preferably, the connecting body is a soft plastic.

[0014] 9. In the above solution, both the main body of the oropharyngeal airway and the mouthguard portion are hollow quasi-elliptical-shaped structures.

[0015] 7. In the above solution, both the main body of the oropharyngeal airway and the mouthguard portion are made of plastic material.

[0016] Due to the application of the above technical solutions, the present utility model has the following advantages compared with the prior art:

[0017] 1. The oropharyngeal airway with self - adaptive adjustment of the front - end curvature of the present utility model has a groove provided on one side of the traditional airway close to the upper jaw, which changes the integrity of the airway body. Due to the characteristics of the plastic material of the oropharyngeal airway, the second airway has a certain degree of mobility. When the second airway contacts the patient's upper jaw, due to its mobility, the bent part in contact and the second airway will lift in the direction of the tongue body and no longer exert pressure on the upper jaw. Since the traditional airway needs to be fixed at the mouthguard part and the baffle (such as straps or adhesive tapes), the end of the airway may cause damage to the upper jaw, while the self - adaptive adjustment oropharyngeal airway of the present application can avoid damaging the upper jaw.

[0018] 2. The oropharyngeal airway with self - adaptive adjustment of the front - end curvature of the present utility model has a groove provided on the oropharyngeal airway while maintaining the overall integrity of the oropharyngeal airway. And due to the plasticity of the curvature at the opening, it fits better with the physiological curvature of the patient's upper jaw. Due to the downward pressure of the tongue body, the position of the airway in the pharyngeal cavity is more fixed and not easily dislodged. Brief Description of the Drawings

A groove 2 is provided on one side of the oropharyngeal airway main body 1 that fits the upper jaw. The oropharyngeal airway main body 1 is of an integrally formed structure, and the groove 2 is provided on this structure.

[0026] The oropharyngeal airway main body 1 is a hollow arc-shaped structure. The groove 2 divides the oropharyngeal airway main body 1 into three parts, including a first airway 11, a second airway 12, and a bending part connecting the first airway 11 and the second airway 12. The first airway 11 and the second airway 12 are bent through the bending part. First anti-scratch parts 110 and second anti-scratch parts 120 are provided on the sides of the first airway 11 and the second airway 12 close to the groove 2.

[0027] The length of the second airway 12 accounts for 1 / 4 of the length of the entire oropharyngeal airway main body 1.

[0028] A guiding section 121 is provided at one end of the second airway 12 away from the groove 2. The guiding section 121 extends towards the arc center side of the second airway 12, and a third anti-scratch part is provided on the side of the guiding section 121 away from the arc center side.

[0029] A dental pad part 3 is connected to one end of the first airway 11 away from the groove 2. When the oropharyngeal airway is used, the dental pad part 3 is placed in the oral cavity, and the second airway 12 extends deep into the throat. A blocking piece 4 is provided at one end of the dental pad part 3 away from the oropharyngeal airway main body 1.

[0030] The oropharyngeal airway main body 1 and the bite block portion 3 are both hollow quasi-elliptical structures.

[0031] Embodiment 2: A front-section arc self-adaptive adjustable oropharyngeal airway, comprising an oropharyngeal airway main body 1. A groove 2 is provided on one side of the oropharyngeal airway main body 1 that fits the upper jaw. The oropharyngeal airway main body 1 is a split structure, and a first airway 11 and a second airway 12 are connected together through a bending portion. The connecting body is made of a material that is tough, not easily broken, and has a certain folding arc.

[0032] The oropharyngeal airway main body 1 is a hollow arc structure. The groove 2 divides the oropharyngeal airway main body 1 into three parts, including a first airway 11, a second airway 12, and a bending portion connecting the first airway 11 and the second airway 12. The first airway 11 and the second airway 12 are bent through the bending portion. First anti-scratch portions 110 and second anti-scratch portions 120 are provided on one side of the first airway 11 and the second airway 12 close to the groove 2.

[0033] The length of the second airway 12 accounts for 1 / 3 of the length of the entire oropharyngeal airway main body 1.

[0034] One end of the second airway 12 away from the groove 2 is provided with a guiding section 121. The guiding section 121 extends toward the arc center side of the second airway 12, and a third anti-scratch portion is provided on the side of the guiding section 121 away from the arc center.

[0036] The oropharyngeal airway main body 1 and the bite block portion 3 are both hollow quasi-elliptical structures.

[0037] The above content of the present utility model is further explained as follows:

[0038] A groove is provided on the oropharyngeal airway. When in use, the second airway of the oropharyngeal airway main body 1 extends deep into the throat. When the groove contacts the patient's upper jaw, due to its mobility, the contacted oropharyngeal airway main body 1 will be lifted in the direction of the tongue body, no longer exerting pressure on the upper jaw, and thus the damage to the upper jaw by the second airway during the fixation at the oral end of the traditional airway will not occur.

[0039] Although a groove is provided on the oropharyngeal airway, the integrity of the overall oropharyngeal airway is maintained. And due to the plasticity of the arc at the opening, it fits better with the physiological arc of the patient's upper jaw. Due to the downward pressure of the tongue body, the position of the airway in the pharyngeal cavity is more fixed and not easily dislodged.
