Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-Figure 5 This utility model discloses an adjustable jawbone fixation device, including a mandibular support plate 10 and an elastic band 20. A drive mechanism 30 is connected between the two ends of the elastic band 20, and a cooling mechanism 40 is connected to the elastic band 20. A pair of first cavities 130 are opened in the mandibular support plate 10, and the elastic band 20 passes through the two first cavities 130. A pair of sliders 50 are fixedly connected to the elastic band 20, and the sliders 50 are slidably connected to the first cavities 130. A tension spring 60 is fixedly connected between the sliders 50 and the inner wall of the first cavity 130. Two pairs of hoses 70 are filled in the elastic band 20.

[0023] Specifically, the bottom end of the mandibular support plate 10 is threaded with two fastening bolts 80, which are pressed against the middle part of the elastic band 20. The top surface of the mandibular support plate 10 is integrally connected with a plastic soft film 90, and the mandibular support plate 10 has an arc-shaped structure.

[0024] In this embodiment, the elastic band 20 can be fixed. After the elastic band 20 is fixed, the fastening bolt 80 will not squeeze the hose 70, so it will not interfere with the circulation of coolant inside the hose 70. The plastic soft film 90 can play a soft role and improve wearing comfort.

[0025] Specifically, the top surface of the plastic soft film 90 has an oval opening 100 that extends to the bottom of the chin support plate 10. The top surfaces of the plastic soft film 90 and the chin support plate 10 have multiple first ventilation holes 110. The outer wall of the elastic band 20 has multiple second ventilation holes 120, and the second ventilation holes 120 are located between two adjacent hoses 70.

[0026] This implementation plan provides good breathability and also plays a good auxiliary role in improving the patient's wearing comfort.

[0027] Specifically, the drive mechanism 30 includes a headband 31, the headband 31 has a second cavity 32 inside, a micro circulation pump 33 is fixedly installed in the second cavity 32, the two ends of the hose 70 are fixedly connected to the two ends of the headband 31 respectively, the hose 70 communicates with the second cavity 32, and two perforated sealing strips 34 are fixedly connected to the inner wall of the second cavity 32, the micro circulation pump 33 is located between the two perforated sealing strips 34.

[0028] In this embodiment, the headband 31 is equipped with a switch and a battery, which is the prior art. The switch can turn the micro circulation pump 33 on and off, while the battery can power the micro circulation pump 33. By starting the micro circulation pump 33, the coolant inside the hose 70 can be circulated, thereby achieving a good cooling effect.

[0029] Specifically, the cooling mechanism 40 includes a storage box 41, a circular groove 42 on the front of the storage box 41, a sealing cap 43 connected to the inner thread of the circular groove 42, an elastic band 20 passing through the storage box 41, an ice pack placed inside the storage box 41, and the storage box 41 has a double-layer inner liner.

[0030] In this embodiment, the storage box 41 can store ice packs, and the ice packs are attached to the outer surface of the hose 70 to cool the hose 70. Since the storage box 41 uses a double-layer inner liner, it also has a good heat preservation effect, which can effectively increase the service life of the ice packs.

[0031] The working principle and usage process of this utility model are as follows: Loosen the fastening bolt 80, pull the elastic band 20, adjust the length of the elastic band 20, and after completion, turn the fastening bolt 80 forward and squeeze the elastic band 20 to fix the adjusted elastic band 20. Then, in conjunction with the entire jawbone fixation device, the mandibular support plate 10 fits against the patient's mandible, while the headband 31 is located on the top of the patient's head. In hot weather, put the ice pack into the storage box 41, then close the sealing cap 43, and start the micro circulation pump 33 to circulate the coolant inside the hose 70. At this time, the internal temperature of the elastic band 20, the headband 31, and the mandibular support plate 10 will all drop, thereby bringing coolness to the patient's skin and improving the patient's wearing comfort.
