[0025] See also Figure 1-7 A spinal trauma external fixation device comprises a back pad 1, which serves as a support structure for the patient's back. The back pad 1 is rotatably connected to a padded side panel 2 on the outside. The padded side panel 2 facilitates wearing the back pad 1 and a chest pad 4. The padded side panel 2 is a soft panel structure that can undergo a certain bending deformation. The top of the padded side panel 2 is fixedly connected to a shoulder strap 3, and the front of the padded side panel 2 is movably connected to a chest pad 4. The chest pad 4 serves as a support structure for the patient's chest and abdomen.

[0026] The anti-pressure sore structure 5 includes an airbag 501, a first breathable gauze layer 502, a foam pad layer 503, a magnet layer 504 and a second breathable gauze layer 505. The front of the back pad 1 is fixedly connected with the airbag 501, and the airbag 501 is used to flexibly support the patient's back. The inside of the back pad 1 is fixedly connected with the first breathable gauze layer 502, and the first breathable gauze layer 502 increases the breathability of the back. The back of the back pad 1 is paved with a foam pad layer 503, and the foam pad layer 503 increases the softness of the back of the back pad 1 to achieve a buffering effect. The front of the chest pad 4 is paved with a magnet layer 504, and the magnet layer 504 is used to massage the patient's chest and abdomen to accelerate blood circulation. The inside of the chest pad 4 is fixedly connected with the second breathable gauze layer 505, and the second breathable gauze layer 505 increases the breathability of the chest and abdomen.

[0027] The adjustment structure 6 includes a support rod 601, a first telescopic rod 602, a threaded screw 603, a second telescopic rod 604 and a latex pad 605. The outside of the cushion side panel 2 is fixedly connected with the support rod 601, and the inside of the support rod 601 is slidably connected with the first telescopic rod 602. The knob rod is rotated to engage the threaded screw 603, so that the first telescopic rod 602 drives the upper cushion side panel 2 to rise along the threaded screw 603, driving the internal rotation of the support rod 601 connected to the threaded screw 603, and the inside of the cushion back panel 1 is slidably connected with the second telescopic rod 604. The outside of the second telescopic rod 604 is fixedly connected with the latex pad 605. The latex pad 605 has a memory rebound effect, which is convenient for storage and automatic expansion, so as to avoid vacant parts after the cushion back panel 1 is adjusted and moved, causing discomfort to the patient's back.

[0028] When implementing, follow these steps:

[0029] 1) First, the airbag 501 is used to increase the flexible support effect of the backrest 1, and the first breathable yarn layer 502 is used to increase the air permeability of the patient's back;

[0030] 2) Then, the magnetic layer 504 is used to perform magnetic massage on the chest and abdomen of the patient to increase the blood circulation effect, and the second breathable yarn layer 505 is used to increase the air permeability of the chest and abdomen of the patient;

[0031] 3) Rotate the knob outside the support rod 601, and use the bevel gear to engage the threaded screw 603 to rotate, so that the first telescopic rod 602 moves up and down along the threaded screw 603;

[0032] 4) Finally, the two backrest plates 1 are slidably adjusted to a distance under the guidance of the second telescopic rod 604, so as to facilitate adjustment according to the height of the user.

[0033] according to Figure 2 , Figure 4 and Figure 5 As shown, the interior of one of the back pads 1 is a sliding cavity structure, and the second telescopic rod 604 and the latex pad 605 on the top of the other back pad 1 both extend into the sliding cavity. Two No. 1 air slots are provided inside the two back pads 1, and four air bags 501 are respectively located on the front of the two back pads 1 to provide flexible support for the patient's back. The four first breathable gauze layers 502 are respectively located inside the four No. 1 air slots, thereby increasing the breathability of the back pad 1 and avoiding the growth of pressure sores on the back.

[0034] according to Figure 1 and Figure 6 As shown, the four magnetic layers 504 are respectively located on the back of the two chest pads 4 and are attached to the chest and abdomen of the patient. The blood circulation capacity is increased through magnetic therapy massage to avoid blood flow obstruction. The two second breathable gauze layers 505 are respectively located inside the two No. 2 air slots, which can increase the air permeability of the chest pad 4.

[0035] according to Figure 1 , Figure 4 and Figure 5 As shown, the four cushion side panels 2 are all arc plate structures, and are connected to the four first telescopic rods 602 up and down through four support rods 601, two of which are internally rotatably connected with threaded screws 603. The button rods outside two of the support rods 601 are rotated, and the button rods drive the two threaded screws 603 through the engagement of the first bevel gear and the second bevel gear.

[0036] according to Figure 5 and Figure 7 As shown, the bottoms of the two first telescopic rods 602 are connected to the external threads of the two threaded screws 603 through sliders, and the threaded screws 603 drive the first telescopic rods 602 to rise so as to adjust the spacing between the cushion side panels 2, thereby driving the two cushion back panels 1 to adjust the spacing.

[0037] according to Figure 5 and Figure 7 As shown, when the distance between the two backrest plates 1 becomes larger, the second telescopic rod 604 will slide out to the outside of the sliding cavity in one of the backrest plates 1, and drive the latex pad 605 to move to the outside of the sliding cavity. The latex pad 605 is a memory latex structure with greater elasticity, which is convenient for storage and automatic expansion, thereby making up for the gap caused by the change in the distance between the backrest plates 1 and avoiding discomfort to the patient's back.

[0038] In summary, the spinal trauma external fixation device uses the back pad 1 as a protective plate to support the patient's back, and an air bag 501 is arranged on the back pad 1 to flexibly support the patient's back. At the same time, an air groove is opened inside the back pad 1, and the first breathable gauze layer 502 is used to increase the ventilation effect of the back. A foam pad layer 503 is arranged on the back of the back pad 1 to increase the softness of the back of the back pad 1. The chest pad 4 is used as a protective plate for the chest. At the same time, the chest pad 4 is connected to the soft cushion side plate 2 through a safety buckle, which is convenient for disassembly and replacement, and the second breathable gauze layer 505 is used to increase the ventilation effect of the patient's chest. At the same time, the magnetic therapy massage of the chest and abdomen is performed by the magnet layer 504 to increase the blood circulation effect, thereby increasing the breathability of the chest and back, and flexibly supporting the patient's back, reducing the pressure on the back, and avoiding the possibility of pressure sores on the chest and back. The problem that the upper and lower plates used in the external fixation support device for orthopedic spinal trauma in the above-mentioned background technology lack the structure of flexible support for the chest and back of the injured person, and long-term bed rest may cause pressure sores.
