[0031] It should be noted that the modifications of "one" and "multiple" mentioned in the present disclosure are illustrative rather than restrictive. Those skilled in the art should understand that unless otherwise clearly stated in the context, it should be understood as "one or more".

[0032] The present disclosure will be described in detail below with reference to the drawings and in combination with the embodiments.

[0033] Refer toFigures 1-10 As shown in Figures 1-10 , an airbag type cervical fixing brace of the present invention includes a front bracket and a rear bracket. The front bracket and the rear bracket are connected by four groups of buckle devices, two of which are located at the upper ends of the front bracket and the rear bracket and are symmetrically arranged, and the other two groups of buckle devices are located at the lower ends of the front bracket and the rear bracket and are symmetrically arranged; the front bracket and the rear bracket have the same structure and are symmetrically arranged. The front bracket includes an upper support plate, a lower support plate arranged below the upper support plate, a plurality of elastic strips arranged at equal intervals and fixed at both ends on the upper support plate and the lower support plate respectively, a support assembly arranged on the upper support plate, a plurality of airbags arranged alternately with the plurality of elastic strips and fixed at both ends on the upper support plate and the lower support plate, a cavity arranged in the lower support plate, and an inflation assembly arranged on the lower support plate and used for injecting air into the cavity; the cavity is communicated with the plurality of airbags.

[0034] First, the buckle device can quickly connect the upper support plate and the lower support plate, and can be adjusted according to the thickness of the patient's neck, so as to facilitate the adjustment of the tightness after wearing. Through the setting of the support assembly and the plurality of airbags, the support strength of the patient's cervical vertebra can be adjusted, and the support assembly can self-adaptively support according to the arc of the patient's mandible; air is injected into the cavity through the inflation assembly, and the air in the cavity enters the plurality of airbags respectively. After the plurality of airbags are inflated, they expand themselves, causing the upper support plate and the lower support plate to move relatively away from each other, deforming the plurality of elastic strips. The plurality of elastic strips can first give a certain supporting force to the upper support plate to support and fix the patient's cervical vertebra. By adjusting the pressure in the cavity as described above, the strength of the support for the cervical vertebra can be adjusted; this airbag cervical fixing brace can comfortably support the cervical vertebra and make the cervical vertebra form a backward-leaning posture, so as to stretch the cervical vertebra, open the joint space between the cervical vertebrae, and retract the bulging or protruding cervical disc, ultimately achieving the improvement of a series of complications such as nerve compression caused by the bulging or protruding cervical disc, and improving the symptoms of the physiological curvature of the cervical vertebra.

[0035] Specifically, the inflation assembly includes an inflation tube, a first hollow ring fixed on the inner wall of the inflation tube, two first chutes symmetrically arranged on the inner wall of the inflation tube, a sliding plate with both ends slidably arranged on the two first chutes, a pull rod fixed at one end on the sliding plate, a first sealing ring cooperated with the first hollow ring and fixed at the other end of the pull rod, and a first spring sleeved on the pull rod and fixed at both ends on the sliding plate and the first hollow ring respectively; after the inflation tube is connected to an air pump (the air pump can be obtained by purchasing in the market), when injecting air into the cavity, the first sealing ring is pushed to move, causing a gap between the first sealing ring and the first hollow ring, so that air can be injected into the cavity. The first spring self-adaptively expands and contracts. When stopping injecting air into the cavity, the first spring resets the first sealing ring. Through the above setting, the function of a one-way valve is achieved, avoiding the air in the cavity from flowing out through the inflation tube and maintaining the pressure in the cavity.

[0036] Specifically, the inflation assembly further includes a pressure relief pipe, a second hollow ring fixedly arranged on the inner wall of the pressure relief pipe, a first adjusting screw rod rotatably arranged on the pressure relief pipe, a push rod rotatably arranged at one end of the first adjusting screw rod, a second sealing ring slidably sleeved on the push rod and cooperating with the second hollow ring, and a second spring sleeved on the push rod and fixedly arranged at both ends on the second sealing ring and one end of the push rod respectively; when the pressure in the cavity is too high, the second sealing ring is moved, the second spring is compressed, a gap is generated between the second sealing ring and the second hollow ring, and the air in the cavity can be discharged from the pressure relief pipe; by rotating the first adjusting screw rod, the push rod is moved, the second spring is telescoped, so that the thrust on the second sealing ring is changed, thereby changing the pressure in the cavity and finally changing the magnitude of the supporting force on the cervical vertebra.

[0037] Specifically, the support assembly includes a plurality of second chutes corresponding to the plurality of air bags and arranged on the upper support plate, a plurality of first sliders respectively slidably arranged in the plurality of second chutes, a plurality of ejector rods respectively movably arranged through the plurality of first sliders, a plurality of fixed circular plates respectively fixedly arranged at one ends of the plurality of ejector rods, a plurality of spherical balls respectively fixedly arranged at the other ends of the plurality of ejector rods, a plurality of bottom plates respectively rotatably sleeved on the plurality of spherical balls, an elastic adaptor plate fixedly arranged on the plurality of bottom plates at the same time, and a plurality of third springs respectively sleeved on the plurality of ejector rods and fixedly arranged at both ends on the plurality of fixed circular plates and the plurality of first sliders; the support assembly further includes a plurality of slide rods slidably arranged on the upper support plate and fixedly arranged at one ends on the plurality of first sliders respectively, and a plurality of tension bars fixedly arranged at both ends on the plurality of bottom plates and the lower support plate respectively; the other ends of the plurality of slide rods are respectively inserted into the plurality of air bags; the plurality of tension bars are arranged corresponding to the plurality of air bags one by one; the patient's mandible is in contact with the elastic adaptor plate, and the elastic adaptor plate can perform self-adaptive deformation according to the arc of the mandible. Specifically, after the air in the cavity enters the air bag, the slide rod is moved, thereby pushing the first slider to move, making the ejector rod move together, and causing the bottom plate to displace. Since the ejector rod is movably arranged through the first slider and is provided with a third spring, the ejector rod performs self-adaptive movement relative to the first slider, the bottom plate rotates self-adaptively with the ejector rod, the plurality of first sliders move self-adaptively in the plurality of second chutes, the plurality of ejector rods move self-adaptively relative to the plurality of first sliders, and the plurality of bottom plates rotate self-adaptively relative to the plurality of ejector rods. Finally, the elastic adaptor plate can be deformed according to the arc of the patient's mandible, that is, the elastic adaptor plate can better fit the mandible and play a good supporting role; after the plurality of air bags are inflated, the plurality of tension bars are tightened and limit the plurality of air bags, greatly reducing the expansion of the plurality of air bags in the direction of the neck. Even if the cervical vertebra fixing brace only has the upper support plate, the lower support plate and the elastic adaptor plate on the support assembly in contact with the patient, the comfort of the patient after wearing is improved. Moreover, the whole cervical vertebra fixing brace is in a gourd shape. In this way, when the plurality of air bags are inflated, the carotid sinus of the patient can be completely avoided from being compressed, and the adverse event of instant asphyxia and death caused by compressing the carotid sinus can be eliminated.

[0038] Specifically, the buckle device includes a first cylinder and a second cylinder, a circular card slot provided on the first cylinder, a driven shaft rotatably provided at one end on the second cylinder, a first rotating plate rotatably provided at one end on the other end of the driven shaft, a third chute provided on the first rotating plate, a second slider slidably provided in the third chute, a second rotating plate rotatably provided at one end on the second slider, a second adjusting screw threadedly engaged with the second slider and rotatably provided at both ends on the first rotating plate, a fourth chute provided on the second rotating plate, a third slider slidably provided in the fourth chute, a moving rod slidably provided on the second rotating plate and fixedly provided at one end on the third slider, a buckle plate fixedly provided at the other end of the moving rod, a kidney-shaped hole provided on the buckle plate, a fourth spring sleeved on the moving rod and fixedly provided at both ends on the third slider and the second rotating plate respectively; the buckle device further includes a scale provided on the second rotating plate, a first insertion hole provided on the driven shaft, a second insertion hole corresponding to the first insertion hole and provided on the first rotating plate, and a plug rod slidably provided at one end in the second insertion hole; the first cylinder and the second cylinder are respectively installed on the front bracket and the rear bracket, the buckle plate is hung on the first cylinder and located within the circular card slot. Rotate the first rotating plate to make the second rotating plate rotate together, and pull the second rotating plate to move, so that the buckle plate is engaged with the first cylinder, enabling the third slider to move adaptively and the fourth spring to stretch and contract adaptively, that is, the first rotating plate itself has an adaptive stretching and contracting function. Through the above settings, the front bracket and the rear bracket can be quickly connected and fixed. By rotating the second adjusting screw, the second slider moves within the third chute, changing the rotation connection between the first rotating plate and the second rotating plate, thereby causing the first rotating plate and the second rotating plate to move, changing the pulling force of the buckle device on the front bracket and the rear bracket, and adjusting according to the thickness of the patient's neck. That is, through the above settings, it can be quickly connected and fixed, and can also be adjusted according to the thickness of the patient's neck to adjust the tightness after wearing; move the plug rod to make the plug rod in the second insertion hole move towards the first insertion hole direction, so that the plug rod is inserted into both the first insertion hole and the second insertion hole at the same time to fix the first rotating plate, thereby fixing the rotation direction of the first rotating plate and the second rotating plate; there are four groups of the buckle devices, which are respectively located on both sides of the upper support plate and both sides of the lower support plate, and are symmetrically arranged in pairs. The distance between the upper support plates on the front bracket and the rear bracket is different from the distance between the lower support plates on the rear bracket and the front bracket. The driven shaft rotates adaptively. Through the above four groups of buckle devices, the front bracket and the rear bracket can also be fixedly connected. By observing the moving distance of the third slider in the fourth arc chute through the scale, it is ensured that the pulling forces of the two symmetric buckle devices on the front bracket and the rear bracket are consistent, and the pulling forces of the other two symmetric buckle devices are consistent. The pulling forces of these two buckle devices on the front bracket and the rear bracket can be the same or different, and can be adjusted according to the thickness of the upper and lower ends of the patient's neck.

[0039] The above description is only some preferred embodiments of the present disclosure and an explanation of the applied technical principles. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by the specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the above inventive concept.
