Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Usually, the components of the embodiments of the present application described and illustrated herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the present application to be protected, but only represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the scope of protection of the present application.

[0022] Embodiment 1

[0023] This embodiment provides an adjustable head-up and jaw-supporting bracket. Refer to Figure 1 , which includes a rear-neck guard plate 1 and an adjustable jaw support, and the two are connected by a flexible belt 2. The rear-neck guard plate 1 is located at the rear side of the patient's neck and is internally provided with an arc-shaped channel 14 that penetrates from left to right. Two C-shaped arms 3 are symmetrically arranged in the channel, and the ends of these arms 11 support on the mandibular angles on both sides of the patient. The C-shaped arms 3 are slidably connected to the arc-shaped channel 14 and are provided with an adjusting mechanism, which can adjust the extension amount of the arms 11 according to the head circumference of the patient's individual characteristics to ensure that they just right support at the mandibular angles.

[0024] The adjustable mandibular support is composed of a mandibular support plate 4 and a belt-retracting mechanism. The mandibular support plate 4 is located at the patient's mandible, and the belt-retracting mechanism includes a belt-retracting roll 5 fixed at both ends of the mandibular support plate 4. One end of the flexible belt 2 is connected to the back neck guard plate 1, and the other end is connected to the belt-retracting roll 5. These belt-retracting rolls 5 are similar to the structure in a tape measure, and the length of the flexible belt 2 can be adjusted, and have a self-locking function. By adjusting the length of the flexible belt 2, the mandibular support plate 4 can fit the patient's mandible to achieve the effect of supporting the mandible.

[0025] According to the specific conditions of the patient's neck and mandible, the patient can raise his head and fix it at an appropriate angle by adjusting the angle of the mandibular support plate 4. This support design not only provides comfortable support for the patient, but also takes individual differences into consideration, and achieves personalized support effects by adjusting parameters of different parts.

[0026] In this embodiment, the shape of the back neck guard 1 is designed to be shield-shaped, which may be conducive to providing a wider support area to ensure that the patient's neck is fully supported and stable. The shield-shaped back neck guard 1 may have a larger surface area, which can distribute the load more evenly, reduce the pressure concentration on the neck, and thus improve wearing comfort and support. This design may also help to adapt to the neck curves and sizes of different patients and provide a more personalized support experience.

[0027] In this embodiment, a soft silicone pad 9 is provided inside the mandibular support plate 4. This design can provide more comfort and relieve the pressure on the mandibular area, and also help to increase the contact area between the mandibular support plate 4 and the mandibular area, providing better support and stability. The soft silicone material can adapt to mandibular areas of different shapes and sizes, reduce friction and discomfort, and thus improve wearing comfort. This design also helps to reduce the discomfort or damage that may occur when the skin is under pressure, providing users with a better wearing experience.

[0028] Example 2

[0029] Based on Example 1, a further implementation of the C-shaped support arm 11 is provided. Figure 2 :

[0030] In this embodiment, the two C-shaped arms 11 are designed as independent flat arc structures. Their outer ends have cylindrical arc mandibular angle supports 12 wrapped with soft material to support the bilateral mandibular angles and promote the mandibular joint to move forward. The inner ends are L-shaped with a toothed structure toward the middle side.

[0031] Further, the adjusting mechanism includes adjusting gears 6 provided at the connection of the two C-shaped arms 11. These adjusting gears 6 are respectively meshed and connected with the toothed structural surfaces 13 of the two C-shaped arms 11. Strip-shaped windows 7 communicating with the arc-shaped channels 14 are opened on the side walls of the rear neck guard 1, and the central shafts of the adjusting gears 6 extend to the outside of the rear neck guard 1 through these windows. The end of the central shaft is connected with a knob, and the knob is fixedly connected to the surface of the rear neck guard. The adjusting gear and the knob structure are prior arts well-known to those skilled in the art, and will not be elaborated in this embodiment. Specifically, reference can be made to the tightening and loosening adjusting mechanism disclosed in the utility model patent with the application number 201420165456.9. In this tightening and loosening adjusting mechanism, the rotation of the knob can drive the gear to rotate, thereby driving the movement of the rack cooperating with the gear. And when the knob is not rotated, the gear is in a self-locking state; the self-locking state of the gear can also be released by the hook block. With the above structure, in the present utility model, when the knob is rotated, the C-shaped arms 11 will displace with the rotation of the adjusting gears 6 and can extend or retract to both sides respectively. According to actual needs, that is, the head circumference of the patient, when the knob is rotated to an appropriate position, it will be automatically locked. If the position needs to be adjusted, just press the unlock button and then rotate the adjustment again. This design enables the bracket to more personalizedly adapt to the needs and head sizes of different patients and provide a better support effect.

[0032] Embodiment 3

[0033] On the basis of Embodiments 1 and 2, a further implementation manner of the flexible belt 2 is provided:

[0034] In this embodiment, the flexible belt 2 adopts a split design and is connected in the middle by a snap fastener 8. One end of one flexible belt 2 is provided with the plug of the snap fastener 8, and the end of the other flexible belt 2 is provided with the slot of the snap fastener 8. These two cooperate and are connected to fix the left and right flexible belts 2 together. This snap fastener structure is similar to the design of male and female fasteners and can be locked after being inserted into each other. This design is common in fields such as knee pads straps.

[0035] After use, the user can press the unlock button on the tape reel 5, which will unlock the mandibular support plate 4 and place it at the lowest angle, thus releasing the support and fixation of the mandible. Subsequently, the male end of the snap fastener 8 can be pulled out from the female end, so that the rear neck guard 1 and the mandibular support plate 4 can be separated, facilitating the user to remove the entire device. This design makes the whole device easier to use and disassemble, improving the comfort and convenience of the user.

[0036] Embodiment 4

[0037] On the basis of Embodiments 1, 2, and 3, a further preferred implementation manner is provided:

[0038] Optionally, a chest guard plate 10 extending downward is provided on the lower jaw support plate 4. The chest guard plate 10 is connected to the lower jaw support plate 4 through two inverted V-shaped support arms 11, so that the chest guard plate 10 closely adheres to the patient's chest, playing a role in assisting in supporting the entire lower jaw bracket. This design can increase the stability of the overall structure, especially in the case where the bracket needs to be worn for a long time, providing additional support and comfort.

[0039] Optionally, a flexible material is provided on the side of the rear neck guard plate 1 that contacts the skin. This design can reduce the pressure and friction on the neck skin, improve the wearing comfort and reduce the discomfort of the patient.

[0040] Furthermore, the rear neck guard plate 1, the adjustable lower jaw support, the flexible belt 2, the chest guard plate 10 and the support arms 11 are all made of polymer materials instead of metal materials. This design enables the entire bracket to be penetrated by imaging technologies such as X-rays, and the patient can still receive examinations such as X-rays, CT, and MRI while wearing the bracket without affecting the imaging effect. This is very convenient for medical staff, enabling imaging examinations to be carried out when needed without having to remove the bracket.

[0041] The usage method of the present utility model is described as follows:

[0042] The patient lies flat or on the side, places the rear neck guard plate 1 behind the patient's neck, and connects the adjustable lower jaw support to the rear neck guard plate 1. After anesthesia is implemented, the position of the lower jaw support plate 4 is adjusted through the strap adjusting mechanism to make it closely adhere to the patient's lower jaw, helping the patient to raise the head to an appropriate angle and fix the position. Then, rotate the adjustment knob of the C-shaped support arm 11 at the rear of the rear neck guard plate 1 to extend the C-shaped support arm 11 and press against both sides of the mandibular angle, and then make further adjustments to displace the lower jaw and fix it in an appropriate position to complete the operation. During the anesthesia recovery, press the unlocking button at the rotating shaft of the lower jaw support arm 11 to adjust the lower jaw support arm 11 downward to the lowest position, and pull out the connecting male-female buckle 8 to separate the connection between the rear neck guard plate 1 and the adjustable lower jaw support, and then the device can be removed. Then, release the self-locking state of the adjusting gear, rotate the adjustment knob to retract the C-shaped support arm 11 into the rear neck guard plate 1, release the support for the mandibular angle, and then the device can be removed. When testing the effect of this device, the effectiveness of relieving airway obstruction can be judged by the respiratory monitoring parameters of the monitor to ensure that the patient's breathing is unobstructed when wearing and removing the device.
