DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The present utility model will be further described below with reference to specific illustrations.

[0022] Please refer to Figure 1, the present utility model provides a neck brace, which includes a front piece 100 and a rear piece 200 connected to the front piece 100 through two fixing mechanisms 330. After the front piece 100 and the rear piece 200 are connected, they enclose a fixing cavity for fixing the patient's neck. The front piece 100 includes a first support piece 110, two rotating connectors respectively arranged on both sides of the first support piece 110, second support pieces 120 respectively connected to the rotating connectors on both sides, and locking mechanisms respectively arranged on the rotating connectors for locking the positions of the second support pieces 120. A rigid part 111 is fixedly connected to the outer wall of the first support piece 110, and a through cavity 1110 penetrating through the rigid part 111 and the first support piece 110 is opened on the rigid part 111. The through cavity 1110 facilitates tracheal intubation. The second support piece 120 has a chin support part 121 corresponding to the position of the patient's chin. After the patient's neck is accommodated in the fixing cavity, the second support piece 120 can adjust its position in the direction close to or away from the patient's chin, and the locking mechanism is used to lock the adjusted position of the second support piece 120. After the front piece 100 and the rear piece 200 are worn on the user's or patient's neck, adjusting the second support piece 120 actually realizes the adjustment of the overall height of the front piece 100, so that this neck brace can adapt to adjust the position of the second support piece 120 according to the different cervical spine lengths of patients. Different patients can always keep the chin support part 121 padded at the position of the patient's chin, meeting the needs of more different patients, and being able to fit and fix different patients, which means that the chins of different patients can be properly supported, reducing the discomfort caused by long-term neck fixation, with a better experience and stronger comfort. When the neck brace can closely and comfortably fit the patient's neck and chin, it can more effectively limit the unnecessary movement of the neck, contributing to the stability and recovery of the cervical spine. Especially after cervical spine injury or surgery, correct support and fixation are crucial for promoting healing and rehabilitation.

[0023] A silica gel pad (not shown in the figure) is adhered to the surface of the chin support part 121, making the patient feel more comfortable and reducing the occurrence of pressure sores. In order to ventilate and permeate air for the neck in the fixing cavity, the first support piece 110 is also provided with a plurality of front ventilation holes 160 to improve the comfort level of the patient.

[0024] The rotating connecting piece is a pivot. The locking mechanism includes a first annular locking piece 130 provided on the outer wall of the first support piece 110 and capable of allowing the pivot to pass through therein, a second annular locking piece provided on the outer wall of the second support piece 120 and capable of allowing the pivot to pass through therein, a plurality of first locking holes 1310 provided on the first annular locking piece 130, a plurality of second locking holes provided on the second annular locking piece, a locking base body 140 connected to the end of the pivot, and a locking bolt 150 connecting the locking base body 140 with the first locking holes 1310 and the second locking holes. The second support piece 120 is preferably made of a material such as plastic that is not easily deformed. When adjusting the second support piece 120, the second support piece 120 rotates around the pivot. After rotating until the chin can be supported by the chin support portion 121, the movable second support piece 120 is locked, expanding the applicable population, and patients with different cervical spine lengths can be adaptively fixed, with strong versatility.

[0025] Please refer to Figure 2 , the first annular locking piece 130 is provided with a concave groove 131 that is recessed in the direction close to the first support piece 110. A plurality of the first locking holes 1310 are arranged at equal intervals in the concave groove 131 and are distributed around the center of the first annular locking piece 130. The positions of a plurality of the second locking holes correspond to those of a plurality of the first locking holes 1310 one by one. The locking base body 140 includes a circular body 141 rotatably connected to the pivot, a flank 142 fixedly connected to one side of the circular body 141, and a bolt hole opened on the flank 142. The bolt is screwed with the bolt hole, the first locking hole 1310, and the second locking hole to lock the position of the second support piece 120. Before loosening the position of the second support piece 120, first loosen the locking bolt 150 so that the second support piece 120 can rotate around the pivot. The design of the flank 142 enables the operator to easily grasp and rotate the locking base body 140. The locking base body 140 rotates around the pivot to adjust the fixed position of the bolt hole pair. Please refer to Figure 3 , and then use the locking bolt 150 to be screwed with the bolt hole and the corresponding first locking holes 1310 and second locking holes in position to lock the position of the second support piece 120, providing a stable and firm support for the patient. In this way, the method of locking the second support piece 120 has high stability and reliability, ensuring that the neck brace will not loosen or deform during the patient's use. No matter what angle or tightness of support the patient needs, it can be achieved by selecting the corresponding first locking holes 1310 and second locking holes, and the adjustment is convenient and fast.

[0026] Please refer to Figure 4, the rear piece 200 is provided with a plurality of rear ventilation holes 210, and a flexible absorbent pad (not shown in the figure) for adsorbing liquid is pasted on the inner surface of the rear piece 200, and a plurality of through holes corresponding to the positions of the rear ventilation holes 210 are formed in the flexible absorbent pad. When there is a wound on the patient's neck, after wearing the neck brace, the wound position may be prone to exudate or bleeding. The flexible absorbent pad can be made of sponge material. When the patient's exudate or bleeding condition is relatively serious, it is convenient to replace the flexible absorbent pad in time to prevent liquid from oozing out and contaminating clothes or quilts.

[0027] The rear piece 200 has a first contact portion 220 and a second contact portion 230 arranged at longitudinal intervals. Both the first contact portion 220 and the second contact portion 230 are adjacent to the edge of the rear piece 200, and the thicknesses of the first contact portion 220 and the second contact portion 230 are less than the thickness of the central portion of the rear piece 200. After the rear piece 200 is worn on the neck, the first contact portion 220 contacts the patient's back, and the second contact portion 230 contacts the patient's head. The thicknesses of the first contact portion 220 and the second contact portion 230 being less than the thickness of the central portion of the rear piece 200 can play a role in reducing the pressure on the contact parts to prevent pressure sores.

[0028] Two air bags 240 arranged at transverse intervals are provided on the inner surface of the rear piece 200. The air bags 240 are connected to an external air source through an air injection joint 250 distributed on the outer wall of the rear piece 200. When the patient wears the neck brace after the operation, the two air bags 240 are respectively located on both sides of the patient's neck. By relying on filling the air bags 240, the tightness of the circumferential fixation of the neck brace can be adjusted, which can be applied to more patients with different body fat and thinness, expanding the applicable group and saving costs.

[0029] Please continue to refer to Figure 4 , a measuring mechanism 260 is detachably connected to the central portion of the rear piece 200. The measuring mechanism 260 includes a buckle 261 buckled to the rear piece 200, and two soft measuring tapes 262 respectively arranged on both sides of the buckle 261. Both the upper end surface and the lower end surface of the soft measuring tape 262 have scale marks 2620. After the two soft measuring tapes 262 are unfolded, the non-connected ends of the soft measuring tapes 262 extend beyond the rear piece 200. When the patient's neck is fixed in contact with the rear piece 200, by using the two soft measuring tapes 262 in cooperation, the wound on the patient's neck can be measured to accurately obtain the wound data.

[0030] The fixing mechanism 330 includes a first fixing strap 310 connected to the rigid part 111 and distributed adjacent to the through cavity 1110, and a second fixing strap 320 connected to the outer wall of the rear piece 200. The first fixing strap 310 and the second fixing strap 320 are bonded by Velcro. Through the cooperation of the bonded first fixing strap 310 and second fixing strap 320, the tightness when the front piece 100 and the rear piece 200 are fixed can be adjusted conveniently and quickly, and it can be more closely fixed to different patients, with strong practicability.

[0031] This neck brace: First, the second support piece 120 can be rotated to adjust its position, so that the chins of patients with different cervical spine lengths can be properly supported by the chin support part 121. After the locking mechanism locks the position of the movable second support piece 120, the second support piece 120 can provide stable and firm support to the patient, and the chins of different patients can be properly supported, which can improve the comfort of wearing the neck brace. Second, two airbags 240 are provided on the rear piece 200. After wearing the neck brace, the two airbags 240 are located on both sides of the neck. The inflated airbags 240 are in contact with the patient's neck, which can not only reduce the occurrence of pressure sores, but also adjust the tightness of the fixing cavity circumferentially by adjusting the inflation degree of the airbags 240, so as to meet the needs of patients with different body types, expand the applicable group, and have strong versatility. Third, the measurement mechanism 260 using snap connection can accurately measure the wound, with more diverse and practical functions.
