Description

Technical Field

[0001] This application relates to the technical field of sacroiliac joint rehabilitation, and particularly to a sacroiliac joint training device. Background Art

[0002] Affected by factors such as age, physique, and genetics, patients may develop sacroiliac arthritis. The chondrocytes in the joint cartilage of sacroiliac arthritis have low activity, the supporting force of soft tissues such as hip muscles weakens, and the cartilage shows degenerative changes. In the treatment plan, patients need to carry out progressive physical exercises to prevent excessive joint movement and load, and avoid mechanical joint injuries. Exercising the relevant muscle groups can maintain and improve joint mobility to enhance joint stability.

[0003] In existing research, the lesions of the sacroiliac joint can be changed through thigh exercises. In the existing training process, the patient directly pulls an elastic training band with hands and feet, so that the thigh overcomes the elastic potential energy of the training band for resistance training. Without special training and rehabilitation equipment, it is necessary for the patient to use hands and feet simultaneously, increasing the difficulty of rehabilitation training and resulting in poor training effects.

[0004] Therefore, the existing technology still needs to be improved and developed. Summary of the Invention

Detailed implementation manners

[0040] The present application provides a sacroiliac joint training device. To make the purpose, technical solution and effects of the present application clearer and more definite, the following further elaborates on the present application with reference to the accompanying drawings and by way of examples. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0041] As Figure 1 、 Figure 2As shown in the figure, the present application provides a sacroiliac joint training device. The patient can achieve the exercise effect by performing resistance exercises with the thighs 10, thereby realizing the rehabilitation training of the patient's temporomandibular joint. This sacroiliac joint training device mainly includes: a lying component 100, a leg support component 200, and a force application component 300. The lying component 100 is mainly used for the patient to lie down. For the convenience of the patient's use, the lying component 100 is placed flat on the ground or the bed. And the lying component 100 extends in the front-back direction. When the patient lies down, the direction where the feet are located is the back, and the direction where the head is located is the front. The left-right direction when the patient lies down is the left-right direction described in this structure. The direction where the patient's face is located when lying down is the upper, and the direction where the back is located is the lower. The leg support component 200 is arranged at one end of the lying component 100 in the front-back direction, and this position is the rear end. After the patient lies on the lying component 100, the lower leg 11 is lifted and placed on the leg support component 200. The lower leg 11 of the patient is supported by the leg support component 200 at the front end, so that the patient's thighs 10 and lower legs 11 are in a bent state, approximately at a 90° angle. The force application component 300 is located on both the left and right sides of the lying component 100 and is used to provide resistance for the patient's thighs 10 to perform resistance confrontation exercises. The force application component 300 includes at least one force application belt 310. The force application belt 310 is arranged in the left-right direction and is used to be sleeved between the thighs 10 on both sides of the patient. Among them, the force application belt 310 abuts against the front side of one thigh 10 and abuts against the rear side of the other thigh 10, so that one thigh 10 exerts force forward against the force application belt 310, and the other thigh 10 exerts force backward against the force application belt 310.

[0042] The main working principle of the sacroiliac joint training device in the above embodiment is: during training, the patient lies on the lying component 100 with the front side of the body facing up, places the lower leg 11 on the leg support component 200, and the thighs 10 are close to or abut against the leg support component 200, so that the legs are lifted, and the patient's thighs 10 and lower legs 11 are in a bent state (for example, at a 90° or close to 90° angle); as Figure 2 , Figure 3 shown in Figures a and b in, the force application component 300 on both sides drives the force application belt 310, so that the force application belt 310 is sleeved between the thighs 10 on both sides of the patient. The force application belt 310 abuts against the front side of one thigh 10 and abuts against the rear side of the other thigh 10. When one thigh 10 exerts force forward against the force application belt 310, the other thigh 10 exerts force backward against the force application belt 310 at the same time. The thighs 10 on both sides of the patient can perform resistance confrontation training simultaneously. The resistance of the force application belt 310 is applied by the force application component 300, and the patient does not need to hold and apply force. The patient can play the role of exercising the sacroiliac joint only by making one thigh 10 push forward against the force application belt 310 and the other thigh 10 push backward against the force application belt 310, enhancing the relevant muscle groups, realizing the role of maintaining and improving joint activities, and enhancing the stability of the joint.

[0043] The effects of the sacroiliac joint training device in the above embodiments are as follows: When the two thighs 10 of the patient move in different directions (front and back), they have to exert force against the pressure of the force application belt 310, thereby simultaneously performing impedance force confrontation on both thighs 10. Moreover, the same force application belt 310 applies the same resistance to both thighs 10, greatly enhancing the coordination and consistency of the training of both sacroiliac joints, enabling the same training effect for both sacroiliac joints, and achieving good rehabilitation consistency for both sacroiliac joints. This sacroiliac joint training device is specifically used for the rehabilitation training of the sacroiliac joint. It does not require the patient to hold the training belt to exert force, greatly reducing the training difficulty and improving the rehabilitation training effect of the sacroiliac joint.

[0044] As Figure 1 、 Figure 2 、 Figure 4 As shown, the leg support assembly 200 in this embodiment specifically includes: a support main body 210 and an auxiliary support portion 220. The support main body 210 is disposed on the lying component 100, and the support main body 210 is mainly used to support the lower leg 11 of the patient upward, so that the lower leg 11 is placed along the front-back direction and the thigh 10 is placed along the up-down direction. A first flexible pad 211 is provided on the surface of the support main body 210 facing away from the lying component 100. The first flexible pad 211 is used to support the lower leg 11 of the patient. By supporting the lower leg 11 with the flexible pad, the lower leg 11 can be placed more comfortably. The auxiliary support portion 220 is movably disposed along the front-back direction on one side of the support main body 210 and is used to abut against the thigh 10 of the patient. When the thigh 10 moves, there is usually a certain distance from the auxiliary support portion 220. In particular, the thigh 10 moving forward needs to be separated from the auxiliary support portion 220, and the thigh 10 moving backward can also not lean on the auxiliary support portion 220, and the movement of the thigh 10 can still be achieved. Usually, the training process is intermittent. For example, after moving for 10 s, there is a short interval, and then the next movement is carried out. Therefore, during the interval, the thigh 10 can lean on the auxiliary support portion 220, so that the relevant muscles near the sacroiliac joint can be relaxed, improving the training effect. Moreover, by providing the auxiliary support portion 220, more parts of the lower leg 11 can be placed on the support main body 210, and the thigh 10 can lean on the auxiliary support portion 220. When the thigh 10 moves backward, it can push the auxiliary support portion 220 to move, without affecting the training when the thigh 10 moves backward.

[0045] As Figure 2 、 Figure 4 、 Figure 5As shown in the figure, the height of the support main body 210 in this embodiment can be adjusted, so as to adapt to patients of different heights. In a specific structure, a first driving component 230 is arranged on the lying component 100. The first driving component 230 is connected to the support main body 210. The support main body 210 moves away from or close to the lying component 100 under the drive of the first driving component 230. The first driving component 230 can be manually controlled and automatically controlled. For example, a structure of connecting a handle to a screw rod is adopted to realize a hand-cranked lifting. By controlling the first driving component 230, the support main body 210 is driven to lift and lower, so that the support main body 210 is adjustable in the up-and-down direction. Moreover, the auxiliary support part 220 is connected to the support main body 210 and adjusts up and down together with the support main body 210.

[0046] The first driving component 230 in this embodiment realizes automatic control. The first driving component 230 is started by remote control or mobile phone, etc., so that the support main body 210 is lifted and lowered. Therefore, the first driving component 230 specifically includes: a power component 231, a driving screw rod 232, and a screwed sleeve 234. The lying component 100 includes a lying board 110. The lying board 110 extends in the front-rear direction. A fixed bracket 120 is arranged on the lying board 110. The fixed bracket 120 includes a support board 121 and a support column 122. The support column 122 is connected to the upper surface of the lying board 110. The support board 121 is connected to the support column 122 and forms an installation space with the lying board 110. The power component 231 is arranged on the fixed bracket 120 of the lying component 100. The power component 231 is a motor. The motor is fixed to the lower surface of the support board 121 by screws and is located in the installation space. A through hole is formed in the support board 121 of the fixed bracket 120. The driving screw rod 232 passes through the through hole and is rotatably arranged on the support board 121 through a bearing seat. The driving screw rod 232 extends in the up-and-down direction. The lower end of the driving screw rod 232 is connected to the rotating shaft of the motor through a gear set 233. The screwed sleeve 234 is connected to the support main body 210, sleeved on the driving screw rod 232, and is threadedly connected to the driving screw rod 232.

[0047] After the motor is powered on, it can rotate forward and backward, thereby driving the driving screw rod 232 to rotate forward and backward. The driving screw rod 232 only rotates. Through the thread drive of the driving screw rod 232, the screwed sleeve 234 can be lifted and lowered in the up-and-down direction. The screwed sleeve 234 is fixedly connected to the support main body 210. In this way, the lifting control of the support main body 210 is realized through the rotation of the motor.

[0048] As Figure 4 、 Figure 5 、 Figure 6As shown in the figure, in order to make the lifting of the support body 210 smoother, guide columns 240 are respectively fixed at the four corners of the support body 210. The guide columns 240 are arranged in the up and down direction. Guide holes are formed in the fixed bracket 120. The guide columns 240 are embedded in the guide holes and can move in the up and down direction through the guidance of the guide holes.

[0049] As Figure 4 , Figure 5 shown, the auxiliary support part 220 in this embodiment specifically includes: an auxiliary support plate 221, an auxiliary support rod 222, and an auxiliary elastic member 223. A plurality of insertion holes are provided on the support body 210. The auxiliary support rod 222 is inserted into the insertion holes, so that one end is connected to the support body 210 and the other end is fixedly connected to the auxiliary support plate 221. The auxiliary support rod 222 is movably inserted through the support body 210, so that the auxiliary support plate 221 is movably located on the front side of the support body 210. The auxiliary elastic member 223 connects the auxiliary support plate 221 and the support body 210. The auxiliary elastic member 223 is a spring. By sleeving the spring on the auxiliary support rod 222, and one end of the spring is connected to the support body 210 and the other end is connected to the auxiliary support plate 221, the auxiliary support plate 221 has a certain amount of forward and backward movement, and the elastic force exerted by the spring on the auxiliary support plate 221 is not large, which is convenient for the forward and backward movement of the auxiliary support plate 221.

[0050] A cushion 224 is provided on the front surface of the auxiliary support plate 221 in this embodiment. The cushion 224 is relatively soft, improving the comfort of the human leg against it. The cushion 224 is shaped to form two concave thigh placement grooves 225, so that when the patient is training, the thighs 10 can be directly limited in the thigh placement grooves 225 to correct the patient's training posture.

[0051] As Figure 1 , Figure 4 , Figure 6As shown in the figure, the specific structure of the force application component 300 in this embodiment further includes: at least two force application brackets 320, and correspondingly arranged rotating wheels 330. The two force application brackets 320 are respectively located on the left and right sides of the lying component 100, and both ends of the force application belt 310 are respectively connected to the force application brackets 320 on both sides. The rotating wheel 330 is rotatably connected to the force application bracket 320, and the force application belt 310 is sleeved on the rotating wheel 330. After sleeving both ends of the force application belt 310 on the rotating wheel 330, the rotating wheel 330 can be used to limit and guide the force application belt 310. For example, a limit card slot is provided on the rotating wheel 330 so that the force application belt 310 is clamped in the limit card slot. In this way, when the force application belt 310 is in use, it can always be kept on the patient's thigh 10 and its position is relatively fixed, and it is not easy to slide. After both ends of the force application belt 310 are fixed and limited, the middle part of the force application belt 310 is sleeved on both thighs 10 to form an S shape, so as to perform force application training on the thighs 10. The rotating wheel can also be a rotating wheel group, which is composed of multiple rotating wheels. Different rotating wheels are used to guide the force application belt so that the force application belt is wound around the rotating wheel, thereby forming an S shape at the thigh position.

[0052] The force application belt 310 in this embodiment is an elastic belt. If an elastic belt is used, both ends of the elastic belt can be fixed, and the resistance is provided by the elasticity of the elastic belt itself. Alternatively, a winder 340 is provided on the force application bracket 320, and the force application belt 310 is connected to the force application bracket 320 through the winder 340. The winder 340 is used to apply a winding force to the force application belt 310. If the structure of the winder 340 is adopted, the force application belt 310 can be an elastic belt sufficient to provide resistance, or a training belt with a little elasticity. A torsion spring is arranged in the winder 340, and the training belt is driven by the torsion spring, and the resistance for training is applied through the torsion spring. Another structure of the winder 340 can also adopt a structure similar to the winding form of a seat belt.

[0053] The elastic belt in this embodiment is an adjustable elastic belt, so that the resistance of the elastic belt can be adjusted. For example, the length of the elastic belt connected to the winder 340 is adjusted through the winder 340, so that the training resistance during training can be adjusted. It can also be to replace elastic belts with different elastic coefficients to achieve the purpose of adjusting the training resistance.

[0054] Such as Figure 4 、 Figure 5 、 Figure 6As shown in the figure, the force - applying bracket 320 in this embodiment specifically includes: a force - applying support rod 321 and a force - applying adjustment rod 322. The force - applying support rod 321 is adjustably connected to the leg support assembly 200 in the up - and - down direction; in a specific structure, an oblong hole is formed on the support main body 210 of the leg support assembly 200, and the oblong hole extends in the up - and - down direction. A threaded member is connected to the rear end of the force - applying support rod 321 and is connected to the oblong hole through the threaded member, so as to realize the adjustment and movement of the force - applying support rod 321 in the up - and - down direction. In this way, not only can the force - applying bracket 320 move up and down along with the support main body 210 in the up - and - down direction, but also the force - applying support rod 321 can be finely adjusted up and down to make the force - applying support rod 321 suitable for patients of different heights, making the applicability of this device stronger. The force - applying adjustment rod 322 is adjustably connected to the force - applying support rod 321 in the front - and - rear direction; in a specific structure, a long hole is formed in the force - applying adjustment rod 322, and the force - applying adjustment rod 322 can be sleeved on the force - applying support rod 321 through the long hole, so as to realize the front - and - rear movement of the force - applying adjustment rod 322 on the force - applying support rod 321. And an oblong hole is formed on the outer wall of the force - applying adjustment rod 322, and this hole extends in the front - and - rear direction. A threaded member is passed through the oblong hole, so that the force - applying adjustment rod 322 can be tightened by the threaded member to fix the front - and - rear position of the force - applying adjustment rod 322 after adjustment, so that it can be adaptively adjusted to thighs 10 of different thicknesses, improving the applicability of this device. A vertical shaft is fixed to the front end of the force - applying adjustment rod 322, and the vertical shaft is arranged in the up - and - down direction. The rotating wheel 330 is rotatably connected to the vertical shaft through a bearing.

[0055] As Figure 1 , Figure 5 , Figure 7 As shown in the figure, the lying - down component 100 in this embodiment can directly adopt a flat lying - board 110, so that the patient can directly lie flat on the lying - board 110 for training. To enhance the patient's training experience, the lying - down component 100 of this embodiment specifically further includes: a base 130 and a second driving component 140. The base 130 extends in the front - and - rear direction, and the rear end of the lying - board 110 is hinged to the base 130, so that the lying - board 110 is set to be in a movable state. The second driving component 140 is connected between the lying - board 110 and the base 130, and the lying - board 110 rotates up or rotates down around the hinged position under the drive of the second driving component 140. Through the drive of the second driving component 140, the baffle can be set horizontally on the base 130, or the baffle can form a certain angle (such as 20° - 30°) with the horizontal plane, enabling the patient to stand up at a certain angle for training, making the patient's training more comfortable. While not affecting leg training, the patient can read books, watch guiding videos, etc., improving the applicability of this device.

[0056] As Figure 5 , Figure 6 , Figure 7As shown in the figure, the second driving component 140 in this embodiment specifically includes: an adjusting screw 141, an adjusting nut 142, and a hinged connecting rod 143. The adjusting screw 141 is rotatably arranged on the base 130, and the adjusting screw 141 extends in the front-rear direction. The adjusting nut 142 is screwed on the adjusting screw 141. One end of the hinged connecting rod 143 is hinged to the adjusting nut 142, and the other end is hinged to the back surface of the reclining board 110. By rotating the adjusting screw 141, the adjusting nut 142 moves back and forth on the adjusting screw 141. Due to the action of the hinged connecting rod 143, the reclining board 110 can be pushed up and put down.

[0057] In another structure of the device, two force-applying belts 310 can be provided. The two force-applying belts 310 are arranged side by side in the up-down direction. One force-applying belt 310 abuts against the front side of one thigh 10 and the back side of the other thigh 10, and the other force-applying belt 310 abuts against the back side of one thigh 10 and the front side of the other thigh 10. With this structure, the two force-applying belts 310 abut against the thighs 10 on the front and back sides of the thighs 10 respectively, and the two force-applying belts 310 do not affect each other. If one force-applying belt 310 is used, one thigh 10 can only perform anti-resistance movement forward. If it is to perform anti-resistance movement backward, the force-applying belt 310 needs to be repositioned. By using two force-applying belts 310, anti-resistance movement of one thigh 10 can be achieved in the front and back directions without changing the direction of the force-applying belt 310, improving the training efficiency.

[0058] Through this sacroiliac joint training device, the corresponding training method can be realized.

[0059] For example, this solution proposes a training method, including the following steps:

[0060] Step S100: The patient lies flat on the above-mentioned sacroiliac joint training device, puts the force-applying belt on the patient's thighs, and makes the force-applying belt abut against the front side of one thigh and the back side of the other thigh.

[0061] Step S200: Make one thigh of the patient resist the force-applying belt on the front side, and the other thigh resist the force-applying belt on the back side, for 10 s.
