The shape of the bow frame 20 is adapted to the curve of the shoulder of the human body, so that the shoulder rest 1 can be placed on the shoulder securely.

The neck collar body is composed of neck collar sleeve 9, telescopic piece A10, telescopic piece B11 and mandibular bracket 3. The neck collar sleeve 9 is in the shape of a strip, and the lower end of the neck collar sleeve 9 is provided with a dovetail slider 18. The movable cooperation of dovetail chute 8 is so that shoulder support 1 and neck support body are connected and fixed. . The movable suit in the neck collar sleeve 9 is provided with a telescopic sheet A10 and a telescopic sheet B11, and the neck collar sleeve 9, the telescopic sheet A10 and the telescopic sheet B11 are all made of elastic material, and the telescopic sheet A10 and the telescopic sheet B11 can be connected around the patient's neck. In order to immobilize the patient's cervical spine.

The telescoping sheet A10 and the telescopic sheet B11 are elongated respectively, and the telescopic sheet A10 and the telescopic sheet B11 are fixedly installed with support sheets 16 in an interval shape, and the telescopic sheet A10 and the telescopic sheet B11 between each support sheet 16 are provided with spacers. Air vent 17. The telescoping sheet A10 in the neck collar cover 9 and the telescopic piece B11 are fitted and connected to each other, the upper transmission tooth piece 12 is fixedly installed on the telescopic piece A10 in the neck collar cover 9, and the telescopic piece B11 in the neck collar cover 9 is fixed The lower transmission tooth piece 13 is installed, and the upper transmission tooth piece 12 is provided with a mounting hole, and the lower transmission tooth piece 13 corresponding to the mounting hole is provided with a fixing hole, and a rotating shaft is inserted and connected between the fixing hole and the mounting hole, and one side of the rotating shaft A gear 14 is fixedly installed, and the upper transmission tooth piece 12 and the lower transmission tooth piece 13 are meshed with the gear 14 respectively. One end of the rotating shaft extends to the outer end of the neck support sleeve 9, and the end of the rotation shaft extending to the outer end of the neck support sleeve 9 is threaded. Adjustment knob 15 is arranged. The gear 14 is rotated by rotating the adjustment knob 15. Since the gear 14 is meshed with the upper gear 12 and the lower gear 13 respectively, the upper gear 12 and the lower gear 13 are driven to move in the opposite direction, thereby making the telescopic sheet A10 and the telescopic The sheet B11 is extended to the outside of the neck support sleeve 9 respectively, so as to adjust the lengths of the elastic sheet A10 and the elastic sheet B11 according to the thickness of the patient's neck, so as to better fit the physiological curve of the patient's neck and achieve a better fixation effect. Purpose.

The telescopic sheet A10 and the telescopic sheet B11 are connected to each other through the meshing of the gear 14 with the upper transmission tooth piece 12 and the lower transmission tooth piece 13 respectively. One end of the telescopic sheet A10 extending to the outside of the neck collar sleeve 9 is provided with a buckle 4, and one end of the telescopic sheet B11 corresponding to the buckle 4 is provided with a card slot 5, and the telescopic sheet A10 and the telescopic sheet B11 pass through Buckle 4 and card slot 5 are snapped together.

The top of the neck collar cover 9 is fitted with a chin rest 3, which is composed of an inflatable bag, an air bag 19, a valve 21 and a trachea 7. The inflatable bag is C-shaped, and one side of the inflatable bag is provided with a buckle The other side of the hook 22 and the inflatable bag is provided with a buckle ring 23, and the head end of the inflatable bag is connected with the tail end of the inflatable bag through the snap hook 22 and the buckle ring 23. The inflatable bag is sewn with fixed lines, and the inflatable bag between the fixed lines is connected through the trachea 7, and an opening is arranged on one side of the inflatable bag, and one end of the trachea 7 extends outside the opening, and extends to the trachea outside the opening The end of the 7 is fixedly connected to the air bag 19 through the valve 21, and the air bag 19 is squeezed repeatedly, so that the compressed air enters the inflatable bag in layers through the trachea 7, and the height of the chin rest 3 can be adjusted by adjusting the amount of inflation in the inflatable bag. Adapt to patients with different neck lengths.

When the adjustable neck brace is working, firstly, the shoulder rest seat 2 of the shoulder rest 1 is sleeved on the shoulder from top to bottom through the head, and the bow frames 20 on both sides of the shoulder rest seat 6 are adjusted to fit the patient's shoulders. Connect, then insert the dovetail slider 18 at the lower end of the neck brace body into the dovetail chute 8 connected to the top of the shoulder rest seat 2, so that the neck brace body and the shoulder rest 1 are fixedly connected, because the dovetail chute 8 is along the shoulder rest seat 6 Evenly distributed on the circumferential surface of the top, at this time, the neck collar sleeve 9 forms an arc shape along the patient's neck, and then by rotating the adjustment knob 15, the telescopic sheet A10 and the telescopic sheet B11 are respectively extended to the outside of the neck collar sleeve 9 to a certain length. The buckle 4 and the card slot 5 are fixedly connected to the stretch piece A10 and the stretch piece B11, and then according to the physiological curve of the neck of different patients, the stretch piece A10 and the stretch piece B11 are extended to the neck support sleeve 9 by rotating the adjustment knob 15 The outer length is fine-tuned so that the neck brace can better fix the patient's neck and the patient is more comfortable when wearing it. Then the head end of the inflatable bag is connected with the tail end of the inflatable bag through the active cooperation of the snap hook 22 and the snap ring 23, and the air bag 19 is repeatedly squeezed so that the compressed air enters into layers along the trachea 7. In the inflatable bag, adjust the height of the mandibular support by adjusting the amount of air in the inflatable bag to adapt to patients with different neck lengths, avoiding the wear and tear on the contact skin caused by the patient wearing the neck support for a long time.

The adjustable neck collar has a simple structure and is easy to use. By adjusting the length of the stretch piece A10 and the stretch piece B11 to extend to the length outside the neck collar sleeve 9, it can adapt to patients with different neck physiological curves, making the neck collar more consistent with the curve of the human neck. , to achieve a better fixation effect, adjust the height of the chin rest 3 by adjusting the amount of air in the inflatable bag to adapt to patients with different neck lengths, and avoid wear and tear on the contact skin caused by wearing the neck brace for a long time. It is more comfortable for patients to wear.
