[0002] Ankylosing spondylitis is a disease with inflammation of the sacroiliac joints and spinal attachment points as the main symptoms. It is a chronic inflammatory disease characterized by fibrosis and ossification of the large joints of the limbs, the annulus fibrosus of the intervertebral disc and the connective tissue nearby, as well as joint ankylosis. The treatment of ankylosing spondylitis aims to control inflammation, reduce or relieve symptoms, maintain normal posture and optimal functional position, and prevent deformity. In addition to taking medications, appropriate corrective exercises are also required, otherwise the inflammation will be difficult to improve. Patients can play a good corrective role by wearing auxiliary devices to correct ankylosing spondylitis.

[0003] Especially in the early stages of ankylosing spondylitis, when the joints have not yet become stiff or deformed, patients can use spinal traction to relieve pain symptoms and muscle spasms.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The expressions used in the directions, such as "up, down, left, right, front, and back", are used in combination with the drawings to facilitate the explanation of the solutions. The solutions cannot be limited by the text part alone. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0038] Embodiment 1 of the present invention:

[0039] Assistive devices for ankylosing spondylitis, such as Figure 1-Figure 7 As shown, it includes a base 1, a correction bed 2, a limit block 3, a fixing belt 4, a rotating plate 5, a cylinder 6, a traction plate 7, a fixing assembly 8 and an adaption mechanism 9. The correction bed 2 is fixedly connected to the left side of the top of the base 1, the limit block 3 is fixedly connected to the front and rear sides of the top of the correction bed 2, the fixing belt 4 is clamped on the right side of the top of the correction bed 2, the right side of the correction bed 2 is rotatably connected to the rotating plate 5, the right side of the rotating plate 5 is slidably connected to the traction plate 7, the front and rear sides of the bottom of the rotating plate 5 are fixedly connected to the cylinder 6, the output end of the cylinder 6 is fixedly connected to the traction plate 7, a fixing assembly 8 is provided on the right side of the top of the traction plate 7, and an adaption mechanism 9 is provided on the correction bed 2.

[0040] like Figure 3-Figure 7As shown, the adaptation mechanism 9 for adapting to the shape of the patient's back includes an electric push rod 901, a mounting plate 902, a first slide seat 903, a first elastic member 904, a support plate 905 and a torsion spring 906. A plurality of electric push rods 901 are provided, and one end of the electric push rod 901 is fixedly connected to the correction bed 2, and the other end is fixedly connected to the mounting plate 902. In this embodiment, four electric push rods 901 are symmetrically arranged, and the four electric push rods 901 are respectively fixed to the left and right parts on the front and back sides of the bottom of the correction bed 2, and a mounting plate 902 is fixed between the output ends of the four electric push rods 901. Five first slide seats 903 distributed axially are slidably connected in the middle of the mounting plate 902. First elastic members 904 distributed symmetrically on the left and right are fixed on both the front and back sides between the first slide seat 903 and the mounting plate 902. A support plate 905 is rotatably connected to the top of the first slide seat 903, and two torsion springs 906 distributed symmetrically on the front and back are fixed between the support plate 905 and the first slide seat 903.

[0041] like Figure 6 As shown, the top of the support plate 905 is made of rubber.

[0042] When a patient with ankylosing spondylitis needs spinal correction, the patient can first lie on the correction bed 2, the rotating plate 5 and the traction plate 7, and ensure that the front and rear limit blocks 3 are located under the armpits of the patient on both sides, and then the upper part of the human body is limited and fixed by clamping the fixing belt 4 on the correction bed 2, and then the patient's legs are limited and fixed by the fixing component 8. After the fixation is completed, the cylinder 6 can be started to drive the traction plate 7 and the lower part of the human body to move slowly to the right, while the upper part of the human body remains motionless under the action of the limit block 3 and the fixing belt 4, so that The curved spine is slowly straightened to achieve the effect of traction correction of the spine. During this period, since ankylosing spondylitis can cause the patient's spine to bend and cause deformities such as hunchback, it is difficult for the patient's back to be supported by a flat surface. Therefore, the electric push rod 901 can be started to drive the mounting plate 902, the first slide seat 903, the support plate 905 and other components to move upward until the support plate 905 contacts the back of the human body and is blocked. When the electric push rod 901 continues to drive the mounting plate 902 to move upward, since the support plate 905 is blocked, Therefore, the first slide seat 903 will slide relative to the mounting plate 902, and the first elastic member 904 will be compressed immediately. Since the patient's back and spine are curved, the human back will squeeze the support plate 905, causing the support plate 905 to rotate and fit the human back. The torsion spring 906 will be deformed immediately, so that when the patient lies on the correction bed 2 for traction correction of the spine, the curved spine and back can be supported in a close fit, thereby avoiding that only a small area of ​​the correction bed 2 supports the spine and back, thereby causing spinal discomfort. The traction correction is completed, and the restrictions of the fixing belt 4 and the fixing assembly 8 on the human body are released, and the traction plate 7 is driven to move to the left and reset by the cylinder 6, and then the mounting plate 902, the first slide seat 903 and the support plate 905 are driven by the electric push rod 901 to move downward and reset. During this period, the support plate 905 will rotate in the opposite direction and reset under the action of the torsion spring 906, and the first slide seat 903 and the support plate 905 will move upward relative to the mounting plate 902 and reset under the action of the first elastic member 904.

[0043] Embodiment 2 of the present invention:

[0044] On the basis of Example 1, Figure 2 and Figure 7As shown, it also includes a lifting mechanism 10 for lifting the deformed spine and back, the lifting mechanism 10 is arranged on the mounting plate 902, the lifting mechanism 10 includes a fixed block 1001, a mounting belt 1002, a guide seat 1003, a winding wheel 1004 and a servo motor 1005, the fixed block 1001 is fixedly connected to the right side of the mounting plate 902, the mounting belt 1002 is fixedly connected to the bottom of the fixed block 1001, the front and rear parts of the left side of the mounting plate 902 are fixedly connected to the guide seats 1003, the winding wheel 1004 is rotatably connected between the two guide seats 1003, the front side of the front guide seat 1003 is fixedly connected to the servo motor 1005, the output end of the servo motor 1005 is fixedly connected to the winding wheel 1004, the other end of the mounting belt 1002 is wound around the winding wheel 1004, and the mounting belt 1002 is squeezed and fitted with the first slide seat 903.

[0045] When the patient undergoes spinal traction correction treatment, the servo motor 1005 can be started to drive the winding wheel 1004 to rotate and slowly reel in the mounting belt 1002. When the mounting belt 1002 is reeled in, it will gradually straighten and contact the first slide 903. Since the patient's spine and back are curved, the axially distributed first slide 903 and support plate 905 and other components will not be located on the same horizontal plane. Therefore, when the mounting belt 1002 is straightened, it will contact and squeeze the first slide 903 located on a lower horizontal plane, thereby driving the first slide 903 and support plate 905 and other components located on a lower horizontal plane to slowly move upwards and support and squeeze the human back. The corresponding first elastic member 904 then slowly rebounds, so that the support plate 905 can slowly rise and squeeze the patient's spine, thereby assisting in correcting the patient's spine.

[0046] like Figure 2 and Figure 8 As shown, it also includes a driving mechanism 11 for driving the rotating plate 5 to rotate. The driving mechanism 11 is arranged on the correction bed 2. The driving mechanism 11 includes an arc-shaped electric slide rail 1101 and a second slide seat 1102. The arc-shaped electric slide rail 1101 is fixedly connected to the right side of the bottom of the correction bed 2, and the front and rear parts of the left side of the rotating plate 5 are fixedly connected to the second slide seat 1102. The second slide seat 1102 is slidably connected to the arc-shaped electric slide rail 1101.

[0047] When the patient undergoes spinal traction correction treatment, the arc-shaped electric slide rail 1101 can also be started to drive the rotating plate 5, the traction plate 7 and the lower part of the human body to rotate back and forth, so that the relevant muscle groups of the patient's waist and spine are slightly stretched and relaxed, which helps to enhance muscle strength, thereby improving the flexibility of the spine and helping the spine to restore its normal physiological curve, thereby playing an auxiliary role in correcting the spine.

[0048] like Fig. 9 and Fig.10As shown, it also includes a massage mechanism 12 for massaging the patient's back. The massage mechanism 12 is arranged on the support plate 905. The massage mechanism 12 includes an electric guide rod 1201, a sliding plate 1202, a second elastic member 1203 and a massage head 1204. The two electric guide rods 1201 are respectively fixed to the left and right sides of the support plate 905. The front and rear sliding plates 1202 are slidably connected between the left and right electric guide rods 1201. The massage head 1204 is slidably connected to the top of the sliding plate 1202. Four second elastic members 1203 distributed in a circle are fixed between the massage head 1204 and the sliding plate 1202. The massage head 1204 is squeezed and fitted with the support plate 905.

[0049] like Fig. 9 As shown, the electric guide rod 1201 is a double-direction guide rod.

[0050] When the patient undergoes spinal traction correction treatment, the electric guide rod 1201 can also be started to drive the sliding plate 1202, the second elastic member 1203 and the massage head 1204 to move back and forth. Since the support plate 905 is made of rubber, it will bend downward when supporting the patient's back, so that the support plate 905 contacts and squeezes the massage head 1204, causing the massage head 1204 to move downward, and the second elastic member 1203 is immediately compressed, thereby ensuring that the massage head 1204 is in close contact with the upper part of the support plate 905. Therefore, when the massage head 1204 moves back and forth, it can massage various parts of the patient's back, thereby allowing the patient to relax tense muscles, which is more conducive to the traction plate 7 to traction and correct the spine, thereby improving the patient's experience and comfort.

[0051] like Figure 11-13 As shown, it also includes an auxiliary mechanism 13 for assisting shoulder correction and fixation. Two auxiliary mechanisms 13 are provided and are symmetrically arranged on the correction bed 2. The auxiliary mechanism 13 includes a guide rod 1301, a third slide 1302 and an inflatable component 1303. The two guide rods 1301 are respectively fixed to the front and rear sides of the correction bed 2. The outside of the guide rod 1301 is slidably connected to the third slide 1302, and the middle of the third slide 1302 is fixed to the inflatable component 1303.

[0052] like Fig.12 and Fig.13 As shown, it also includes an opening and closing mechanism 14 for controlling the opening and closing of the third slide 1302. The opening and closing mechanism 14 is arranged on the third slide 1302. The opening and closing mechanism 14 includes a third elastic member 1401, an L-shaped plate 1402 and a guide plate 1403. The L-shaped plate 1402 is fixed to the bottom of the third slide 1302. The third elastic member 1401 is fixed between the third slide 1302 and the guide rod 1301. The guide plates 1403 are fixed to the front and rear parts of the left side of the mounting plate 902. The guide plates 1403 are squeezed together with the adjacent L-shaped plates 1402.

[0053] like Fig.12 and Fig.13 As shown, the bottom of the guide plate 1403 is provided with an inclined surface.

[0054] When the electric push rod 901 drives the mounting plate 902 and other components to move upward, the guide plate 1403 will also move upward and separate from the L-shaped plate 1402. At this time, the L-shaped plates 1402, the third slide seat 1302 and the inflatable component 1303 on the front and rear sides will move toward each other under the action of the third elastic member 1401 in a compressed state until they cooperate with the limit block 3 to limit and fix the patient's shoulder, thereby performing a secondary limit fixation on the patient's shoulder to prevent the patient's body from moving to the right as a whole during spinal traction correction treatment, thereby losing the correction effect. In addition, due to the spinal traction correction, the patient's shoulder is fixed to the limit position by the limit block 3. Deformities such as hunchback caused by bending may also cause shoulder adduction. Therefore, the inflatable component 1303 can be expanded and squeezed to the patient's shoulders, thereby assisting the patient in correcting the shoulders. When the electric push rod 901 drives the mounting plate 902 and the guide plate 1403 and other components to move downward and reset, the guide plate 1403 will contact and squeeze the adjacent L-shaped plate 1402, so that the L-shaped plates 1402 on the front and rear sides, the third slide seat 1302 and the inflatable component 1303 move back to back and reset and release the restriction on the patient's shoulders, and the third elastic member 1401 is immediately compressed.

[0055] Although the present disclosure has been shown and described with reference to specific exemplary embodiments of the present disclosure, it should be understood by those skilled in the art that various changes in form and details may be made to the present disclosure without departing from the spirit and scope of the present disclosure as defined by the appended claims and their equivalents. Therefore, the scope of the present disclosure should not be limited to the above-mentioned embodiments, but should be determined not only by the appended claims, but also by the equivalents of the appended claims.
