Abstract
Description
Technical Field
[0001] This utility model belongs to the field of rehabilitation assistive equipment technology, and specifically relates to an orthopedic rehabilitation training device. Background Technology
[0002] Lower limb rehabilitation training is a way for patients with lower limb injuries to restore their lower limb motor perception function. It generally includes muscle strength training, joint range of motion training, and lower limb gait training. Rehabilitation training is an important means to prevent lower limb muscle atrophy and ultimately restore lower limb function.
[0003] For patients with fractures and other lower limb bone injuries, lower limb rehabilitation training is extremely important and is a crucial foundation for quickly regaining the ability to walk.
[0004] Currently, lower limb rehabilitation training is mostly performed manually by others (medical staff or family members) to assist patients in exercising their lower limbs. This process is time-consuming and laborious, and the training effect is poor, making it difficult to achieve good training results. Therefore, inventing a device that can assist patients to perform lower limb training independently is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0005] This invention provides an orthopedic rehabilitation training device to solve the technical problem that in the prior art, lower limb rehabilitation training is mostly carried out by others manually assisting the patient's lower limbs to move, which is time-consuming, laborious, and has poor training effect.

[0008] The fixed end of the thigh sleeve is provided with a first extension, and elastic elements are provided on both sides of the thigh sleeve.
[0009] The fixed end of the calf sleeve is provided with a second extension. The first extension and the second extension are hinged together. The end of the elastic element away from the thigh sleeve is connected to the calf sleeve. In the initial state, the thigh sleeve and the calf sleeve form a "V" shape.
[0010] To better realize this utility model, further optimizations are made to the above structure. The orthopedic rehabilitation training device also includes a limiting rod, which includes a sleeve and a piston rod.
[0011] The sleeve is a cylindrical structure with an opening at the movable end. The piston end of the piston rod is inserted into the sleeve through the opening and slidably disposed therein. An air inlet and an exhaust outlet are provided on the side wall of the sleeve. Both the air inlet and the exhaust outlet are connected to the cavity between the piston rod and the fixed end of the sleeve. A one-way valve is provided at the air inlet and a normally closed solenoid valve is provided at the exhaust outlet. A control switch for controlling the opening of the normally closed solenoid valve is provided on the normally closed solenoid valve.
[0012] The fixed end of the sleeve is hinged to the movable end of the thigh sleeve, and the movable end of the piston rod is hinged to the movable end of the calf sleeve.
[0013] To better realize this utility model, further optimizations are made to the above structure, wherein the side wall of the thigh sleeve is provided with a pressure block A, and the calf sleeve is provided with a pressure block B;
[0014] The elastic element includes a guide rod and a helical spring. One end of the guide rod is set on the pressure block A. The shape of the guide rod is the same as the movement trajectory of the pressure block B when the calf sleeve moves. The pressure block B is provided with a perforation. The cross-sectional shape of the perforation matches the cross-sectional shape of the guide rod. The helical spring is sleeved on the guide rod, and the two ends of the helical spring are respectively connected to the pressure block A and the pressure block B.
[0015] To better realize this utility model, the above structure is further optimized. Both the thigh sleeve and the calf sleeve are bent into rectangular sheet structures. The cross-sectional shape of both the thigh sleeve and the calf sleeve is "U". A first strap is provided on one side of the thigh sleeve, and the thigh sleeve is fixed to the patient's thigh by the first strap. A second strap is provided on one side of the calf sleeve, and the calf sleeve is fixed to the patient's calf by the second strap.
[0016] To better realize this utility model, the above structure is further optimized. There are two first extensions, and the two first extensions are respectively arranged on both sides of the thigh sleeve.
[0017] There are two second extensions, and the positions of the two second extensions correspond to the positions of the two first extensions, and the two second extensions are hinged to the two first extensions respectively.
[0018] To better realize this utility model, the above structure is further optimized. A rotating shaft is provided on the first extension. The length direction of the rotating shaft is perpendicular to the length direction of the thigh sleeve and parallel to the horizontal plane. The second extension is rotatably mounted on the rotating shaft.
[0019] To better realize this utility model, the above structure is further optimized by providing protective pads inside both the thigh sleeve and the calf sleeve.

[0024] The thigh and calf sleeves in the orthopedic rehabilitation training device provided by this utility model can be worn on the patient's thigh and calf respectively. Under the constraint of this orthopedic rehabilitation training device, in the initial state, the patient's calf bends backward toward the thigh in a "V" shape. During the training process, the patient does not need the assistance of others, but only needs to overcome the tension of the elastic element by coordinating the muscle movements of the calf and thigh. After relaxation, the patient uses the restoring force of the elastic element to drive the calf movement and return to the initial state. Repeat the above steps to achieve a good training effect.

[0033] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0034] In the description of this utility model, it should be noted that, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0035] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0036] In embodiments of this utility model, such as Figure 1 and Figure 2 As shown, the orthopedic rehabilitation training device includes a thigh brace 1 and a calf brace 2; wherein,
[0037] The fixed end of the thigh sleeve 1 is provided with a first extension 11, and elastic elements 3 are provided on both sides of the thigh sleeve 1.
[0038] The fixed end of the calf protector 2 is provided with a second extension 21. The first extension 11 is hinged to the second extension 21. The end of the elastic member 3 away from the thigh protector 1 is connected to the calf protector 2. In the initial state, the thigh protector 1 and the calf protector 2 form a "V" shape. See below. Figure 1 .
[0039] When a patient needs to perform lower limb training, the patient can bend their legs and wear the orthopedic rehabilitation training device, or have it worn with the help of medical staff or family members. Specifically, the thigh sleeve 1 and the calf sleeve 2 are worn on the patient's thigh and calf respectively. At this time, the patient can lie prone on the bed.
[0040] Subsequently, the patient can extend their lower leg forward around their knee. During this extension, the muscles of the patient's lower leg and thigh work together to overcome the tension of elastic element 3, thereby achieving the effect of strengthening muscles. See [link to relevant documentation]. Figure 2 Patients can stop when they extend their lower legs to the maximum angle according to their own situation (the greater the angle of extension, the greater the restoring force of elastic element 3).
[0041] Under the restoring force of the elastic element 3, the lower leg is pulled back to the thigh to the initial state. Repeating the above steps achieves a good exercise effect. During the exercise, the patient can control the extension angle according to their own condition (the recovery of muscle strength) to avoid the situation of being injured again due to the assistance of others, so as to ensure the safety of the orthopedic rehabilitation training device when in use.
[0042] To further improve the safety of the orthopedic rehabilitation training device during use, limit rods 4 are also provided on both sides of the thigh sleeve 1. The end of the limit rod 4 away from the thigh sleeve 1 is hinged to the lower leg sleeve 2. The limit rod 4 can provide a certain support for the patient's lower leg and avoid injury when the patient's strength is insufficient and the restoring force of the elastic element 3 pulls the lower leg to bend quickly towards the thigh.
[0043] Specifically, the limiting rod 4 includes a sleeve 41 and a piston rod 42, see [link / reference]. Figure 1 and Figure 2 ;in,
[0044] The sleeve 41 is a cylindrical structure, and the movable end of the sleeve 41 is provided with an opening. The piston end of the piston rod 42 is inserted into the sleeve 41 through the opening and slidably disposed in the sleeve 41. The side wall of the sleeve 41 is provided with an air inlet and an exhaust outlet. The air inlet and the exhaust outlet are both connected to the cavity between the piston rod 42 and the fixed end of the sleeve 41. A one-way valve is provided at the air inlet and a normally closed solenoid valve is provided at the exhaust outlet. A control switch for controlling the opening of the normally closed solenoid valve is provided on the normally closed solenoid valve.
[0045] The fixed end of the sleeve 41 is hinged to the movable end of the thigh sleeve 1, and the movable end of the piston rod 42 is hinged to the movable end of the calf sleeve 2.
[0046] When the patient controls the extension of their lower leg, the lower leg sleeve 2 pulls the piston rod 42 to move away from the fixed end of the sleeve 41. During this process, the piston rod 42 draws external air into the sleeve 41 through the air inlet. The extension stops when the patient controls the extension of their lower leg to the maximum angle according to their recovery. At this time, the air inside the sleeve 41 supports the piston rod 42, and the restoring force of the elastic element 3 cannot pull the patient's lower leg backward toward the thigh, thus maintaining the extension of the lower leg and avoiding injury when the patient's strength is insufficient and the restoring force of the elastic element 3 pulls the lower leg to bend rapidly toward the thigh.
[0047] Subsequently, the patient can press the control switch to open the normally closed solenoid valve, which in turn opens the exhaust port. Under the action of the restoring force of the elastic element 3, the piston rod 42 is pushed to push the air inside the sleeve 41 outward, so as to slowly reset until it returns to the initial state.
[0048] It should be noted that the structure of the normally closed solenoid valve described above is existing technology and is relatively simple, so it will not be described in detail here. Of course, other valve bodies can also be used to replace the normally closed solenoid valve, that is, any valve body that can be controlled by the patient to open and close.
[0049] In some embodiments, the thigh sleeve 1 is provided with a pressure block A12 on its side wall and the calf sleeve 2 is provided with a pressure block B22.
[0050] The elastic element 3 includes a guide rod 31 and a coil spring 32. One end of the guide rod 31 is mounted on the pressure block A12. The shape of the guide rod 31 is the same as the movement trajectory of the pressure block B22 when the calf sleeve 2 moves. The pressure block B22 has a perforation, and the cross-sectional shape of the perforation matches the cross-sectional shape of the guide rod 31. The coil spring 32 is sleeved on the guide rod 31, and the two ends of the coil spring 32 are respectively connected to the pressure block A12 and the pressure block B22 to ensure the movement trajectory of the calf sleeve 2 and to prevent the coil spring 32 from coming off between the thigh sleeve 1 and the calf sleeve 2 and from deflecting the calf sleeve 2, thereby ensuring the structural stability of the orthopedic rehabilitation training device.
[0051] In some embodiments, the thigh sleeve 1 and calf sleeve 2 described above are both formed by bending rectangular sheet structures, and the cross-sectional shape of both the thigh sleeve 1 and calf sleeve 2 is "U" shaped. See [reference needed]. Figure 1 and Figure 2 The thigh sleeve 1 has a first strap (not shown in the figure) on one side, and the thigh sleeve 1 is fixed to the patient's thigh by the first strap; the calf sleeve 2 has a second strap (not shown in the figure) on one side, and the calf sleeve 2 is fixed to the patient's calf by the second strap, so as to make it easier to wear and remove the orthopedic rehabilitation training device.
[0052] In some embodiments, there are two first extensions 11, with the two first extensions 11 respectively disposed on both sides of the thigh sleeve 1, see [link to previous document]. Figure 2 ;
[0053] There are two second extensions 21, and the positions of the two second extensions 21 correspond to the positions of the two first extensions 11, respectively. The two second extensions 21 are hinged to the two first extensions 11. Preferably, the first extension 11 is provided with a rotating shaft. The length direction of the rotating shaft is perpendicular to the length direction of the thigh sleeve 1 and parallel to the horizontal plane. The second extensions 21 are rotatably mounted on the rotating shaft, so that the lower leg can only rotate around the axis of the rotating shaft, thereby limiting the rotation direction of the lower leg and further improving the safety of the orthopedic rehabilitation training device during use.
[0054] In some embodiments, protective pads (not shown in the figure) are provided inside both the thigh sleeve 1 and the calf sleeve 2 to improve the comfort of the orthopedic rehabilitation training device during use.
[0055] In some embodiments, the orthopedic rehabilitation training device further includes a base plate (not shown in the figure), and a thigh sleeve 1 is disposed on the base plate to provide more stable support for the patient during use, thereby further improving the safety of the orthopedic rehabilitation training device during use.
[0056] Specifically, limit grooves are provided on the base plate;
[0057] The thigh sleeve 1 is provided with a limiting block that matches the limiting groove. The thigh sleeve 1 is locked onto the base plate by the cooperation of the limiting block and the limiting groove.
[0058] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
