DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

[0027] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0028] Embodiment one:

[0029] Reference Figures 1-4A nasopharyngeal airway fixation strap includes a fixation strap body 1 and an airway 2. The fixation strap body 1 is made of a mixture of polyester and spandex or nylon and spandex. The airway 2 and the fixation element 3 are both made of silicone. Furthermore, the size of the airway 2 is not limited; medical personnel can adjust the size of the airway 2 according to the patient's condition (e.g., the size and depth of the affected nasal cavity). The total length of the fixation strap body 1 (including the fixation part and the adjustment part) is much larger than the patient's head circumference. The fixation strap body 1 includes a fixation part and two sets of adjustment parts. The fixation part is used to fix it to the patient's head, and the adjustment parts are used to adjust the size of the fixation part. The airway 2 is provided with a connecting part, which connects to the fixation strap body 1 to fix the airway 2 to the fixation strap body 1. It also includes two sets of pressure-reducing elements 6 and adjustment buckles 8 provided on the fixation strap body 1, with the pressure-reducing elements 6 and adjustment buckles 8 passing through the fixation part and adjustment part.

[0030] Reference Figure 1 and Figure 3 The connecting part includes a fixing member 3 connected to the ventilation hose 2. The fixing member 3 has a connecting hole 4 that communicates with the ventilation hose 2. The fixing member 3 has symmetrically arranged limiting holes 5. The diameter of the connecting hole 4 matches the inner diameter of the ventilation hose 2. The limiting holes 5 are located on both sides of the connecting hole 4. The fixing strap body 1 passes through the limiting holes 5. In this way, when the ventilation hose 2 is in use, the fixing strap body 1 is tied to the patient's head and the fixing member 3 fixes the ventilation hose 2, preventing it from moving in and out with the patient's breathing. The size of the limiting hole 5 matches the size of the fixing strap body 1 to ensure that the fixing strap body 1 passes through stably. When in use, the patient can breathe through the connecting hole 4 on the ventilation hose 2 and the fixing member 3.

[0031] Reference Figures 2-3 The fixing part and the adjusting part overlap slightly. The bending part of the fixing part and the adjusting part pass through the limiting hole 5. By adjusting the length of the overlapping part between the fixing part and the adjusting part, the length of the fixing part can be adjusted. The adjusting part is located on the side of the fixing part away from the patient's skin, which can reduce the friction between the adjusting part and the skin when the patient uses it, thereby improving the patient's comfort.

[0032] The fixing part and the adjusting part overlap slightly, meaning that the part of the fixing belt used for fixing overlaps with the part that can be adjusted.

[0033] Reference Figure 1 and Figure 4, the positioning hole 7 is arranged through the decompression piece 6, the fixing part and the adjusting part are penetrated through the positioning hole 7, the decompression piece 6 is made of wood fiber or foamed plastic polymer material, and it is explained that the size of the decompression piece 6 is greater than the size of the fixing band body 1, so that, in use, the height difference between the decompression piece 6 and the skin of the patient can effectively reduce the pressure sore damage to the skin when the equipment is fixed, and the comfort of the patient is improved; in addition, the fixing band body 1 and the positioning hole 7 of the decompression piece 6 have friction, which can realize the movement of the decompression piece 6 on the fixing band body 1 on the one hand, and can reduce the deviation of the decompression piece 6 in use on the other hand.

[0034] With reference to Figure 1 , the adjusting buckle 8 is annular, the adjusting buckle 8 is sleeved on the fixing part and the adjusting part, the adjusting buckle 8 is made of elastic rubber material, the size of the adjusting buckle 8 can be adjusted, and when assembling, the fixing band body 1 can be passed through the adjusting buckle 8 by expanding the size of the adjusting buckle 8, and after being loosened, the adjusting buckle 8 is tightly attached to the fixing band body 1 under the action of elastic force, so as to play a fixing role, and the length of the fixing part of the fixing band body 1 can be adjusted.

[0035] In the utility model, in use, one end of the fixing band body 1 is first passed through a group of adjusting buckles 8 and decompression pieces 6, then passed through the limiting hole 5 on one side of the fixing piece 3, then sequentially passed through the decompression piece 6 and the adjusting buckle 8, and the decompression piece 6 is arranged at the malar process, and the adjusting buckle 8 is moved to be close to the decompression piece 6, and the setting of one end is completed, and the other end is set repeatedly; because the fixing band body 1 has elasticity and the adjusting buckle 8 is added, it is suitable for patients with any head circumference, and is convenient to wear and take off and easy to take off for cleaning and maintenance; the height difference between the decompression piece 6 and the skin can effectively reduce the pressure sore damage to the skin caused by the fixing setting, realize the safe use of the nasopharyngeal airway tube of the patient, reduce the occurrence of pressure sores, and increase practicality and comfort.

[0036] Example two

[0037] With reference to Figure 1 and Figure 5The length of the fixing part of the fixing belt body 1 is adjusted, the adjusting buckle 8 is designed and adjusted, including an adjusting ball 81, a through hole 82 is formed on the adjusting ball 81, an installation groove 83 is formed in the adjusting ball 81, the installation groove 83 is in communication with the through hole 82, a spring 84 is arranged at the bottom of the installation groove 83, a pressing column 85 is arranged at the end of the spring 84 away from the installation groove 83, a fixing hole 86 is formed on the pressing column 85, wherein the installation groove 83 penetrates the adjusting ball 81 on the side close to the spring 84, the through hole 82 and the fixing hole 86 are located on the same plane, the pressing column 85 extends at least to the outside of the adjusting ball 81, the size of the through hole 82 is greater than the size of the fixing hole 86, and the size of the fixing hole 86 is matched with the size of the fixing belt body 1. Here, in order to facilitate the fixing of the fixing belt body 1, a friction block can be arranged on the side close to each other of the through hole 82 and the fixing hole 86, so as to increase the stability of the fixing belt body 1 during use and prevent the fixing belt body 1 from sliding during use. The fixing belt body 1 can be quickly adjusted and fixed, the efficiency is higher, and the operation is simpler.

[0038] In addition, in order to improve the stability and comfort of the pressure relief part 6 during use, the pressure relief part 6 can be designed as an elastic air bag, and the surface is made of silica gel or wood fiber or foamed plastic polymer material. When in use, it has good pressure relief effect, and when the pressure relief part 6 contacts the patient, the size of the positioning hole 7 can be reduced to increase the pressure received by the fixing belt body 1 during use, thereby reducing the deviation of the pressure relief part 6 during use.

[0039] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
