[0002] Oropharyngeal airway, also known as oropharyngeal ventilator, is a non-tracheal tube non-invasive ventilation tube that can prevent the tongue from falling back, quickly open the airway, and enable the patient to obtain effective ventilation. Oropharyngeal airway is a simple and convenient supraglottic ventilation device that presses down the tongue to prevent the tongue from falling back, supports the palatoglossal arch and uvula, separates the tongue root from the posterior pharyngeal wall, relieves upper airway obstruction, and keeps the airway open;

[0003] After checking the public (announcement) number: CN214762691U discloses an oropharyngeal airway, which discloses that "it can be fixed in the mouth and pharynx of a person without harm; it changes the shortcomings of the traditional single-wing oropharyngeal airway that requires external fixation, avoids the shortcomings of easy allergies and easy falling off; and simplifies the clinical operation steps";

[0004] However, the above-mentioned existing oropharyngeal airway still has some disadvantages when in use. Although the oropharyngeal airway can be fixed in the oral cavity, it is only suitable for patients after anesthesia or in coma. Some drunk people may not cooperate and use their tongue to push the oropharyngeal airway out, which will cause considerable trouble to the emergency medical staff.

[0005] In order to solve the above problems, the present application proposes a bandage-type oropharyngeal airway that can be applied to different face shapes. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 4 As shown;

[0026] A bandage-type oropharyngeal airway suitable for different face shapes comprises an airway body 1, the end of which is fixedly sleeved with a fixing tube 2.

[0027] In this embodiment: after checking the public (announcement) number: CN214762691U discloses an oropharyngeal airway, which discloses that "it can be fixed in the mouth and pharynx of a person without harm; it changes the shortcomings of the traditional single-wing oropharyngeal airway that requires external fixation, avoids the shortcomings of easy allergies and easy falling off; simplifies the clinical operation steps";

[0028] However, the existing oropharyngeal airway still has some shortcomings when in use. Although the oropharyngeal airway can be fixed in the oral cavity, it is only suitable for patients after anesthesia or in coma. Some drunk people may not cooperate and use their tongue to push the oropharyngeal airway out, which will cause considerable trouble to the emergency medical staff. Combined with actual use, this problem is obviously a real problem that is difficult to solve. In view of this, in order to solve this technical problem, a wearable component is added to this application document.

[0029] According to the above content, in order to prevent drunk people from pushing out the airway tube body 1 with their tongues, a wearing component arranged on the fixing tube 2 is also included, which is used to wear the airway tube body 1 on the faces of people with different face shapes;

[0030] The wearing component includes two fixing holes 3, which are symmetrically arranged inside the fixing tube 2. Slide rods 5 are slidably inserted on both sides of the fixing tube 2. The two ends of the slide rod 5 are respectively fixedly connected with a positioning piece 6 and a pull block 7. The positioning piece 6 is located in the fixing hole 3. A spring 8 is movably sleeved on the slide rod 5. The two ends of the spring 8 are respectively fixedly connected with the positioning piece 6 and the inner wall of the fixing hole 3. An adjusting belt 4 is movably inserted in the two fixing holes 3, and the adjusting belt 4 is against the positioning piece 6.

[0031] In this embodiment: pull the pull block 7 so that the pull block 7 drives the slide bar 5 and the positioning piece 6 to compress the spring 8, and then pull the adjusting belt 4 to make the adjusting belt 4 slide in the fixing hole 3, so as to adjust the length of the adjusting belt 4, and then release the pull block 7. At this time, the spring 8 rebounds the positioning piece 6 due to its own elastic force until the positioning piece 6 and the rubber pad 10 are against the adjusting belt 4, so that the adjusting belt 4 can be stably positioned in the fixing hole 3, and then the airway body 1 is inserted into the patient's oral cavity and the adjusting belt 4 is strangled at the back of the patient's head, so that it can be worn conveniently and stably. Since the airway body 1 is slightly curved, it can prevent the patient from having the problem of tongue falling back. By adjusting the length of the adjusting belt 4, it can be suitable for patients with different face shapes.

[0032] In an optional embodiment, the shape of the pull block 7 is a “cylinder”, and the outer surface of the pull block 7 is provided with anti-slip lines 9 .

[0033] In this embodiment, it is convenient for personnel to pull the pull block 7 , and anti-skid patterns 9 are provided on the pull block 7 , which can increase the friction between the personnel's hands and the pull block 7 , thereby helping to solve the problem of slipping when pulling the pull block 7 .

[0034] In an optional embodiment: a rubber pad 10 is fixedly mounted on one side opposite to the two positioning members 6 , and the rubber pad 10 abuts against the adjustment belt 4 .

[0035] In this embodiment, the friction between the rubber pad 10 and the adjusting belt 4 can be increased, thereby further improving the stability of the positioning of the adjusting belt 4.

[0036] In an optional embodiment: the outer surface of the air guide tube body 1 is covered with a soft cover 11, and the soft cover 11 is made of silicone.

[0037] In this embodiment, the soft cover 11 is provided, because the oral cavity and throat of the patient are relatively fragile, and the soft cover 11 is relatively soft, so the patient can be effectively protected.

[0038] According to the above content, the adjustment belt 4 is made of nylon.

[0039] In this embodiment, nylon has good mechanical strength, good toughness, good fatigue resistance, high softening point, wear resistance, heat resistance, and light resistance. Therefore, nylon has strong stability and can help to extend the service life of the adjustment belt 4.

[0040] The working principle and use process of the utility model are as follows: when using, first pull the pull block 7, so that the pull block 7 drives the slide bar 5 and the positioning piece 6 to compress the spring 8, and then pull the adjusting belt 4, so that the adjusting belt 4 can slide in the fixing hole 3, and then release the pull block 7. At this time, the spring 8 rebounds the positioning piece 6 due to its own elastic force until the positioning piece 6 and the rubber pad 10 are against the adjusting belt 4, and the adjusting belt 4 can be stably positioned in the fixing hole 3, and then the airway body 1 is inserted into the patient's oral cavity and the adjusting belt 4 is strangled at the back of the patient's head, which can be conveniently and stably worn. Since the airway body 1 is in a slightly curved shape, it can prevent the patient from having the problem of tongue falling back. By adjusting the length of the adjusting belt 4, it can be suitable for patients with different face shapes. In addition, by providing a soft cover 11, since the patient's oral cavity and throat are relatively fragile, and the soft cover 11 is relatively soft in texture, it can effectively protect the patient.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
