Description

Technical Field

[0001] This invention relates to the field of lower limb rehabilitation technology, and more particularly to a rehabilitation training device for patients with lower limb fractures. Background Technology

[0002] A fracture is a complete or partial break in the continuity of bone structure. When a patient suffers a lower limb fracture, it usually manifests as local deformity, abnormal movement of the limb, and local swelling. Therefore, patients with lower limb fractures usually need to undergo rehabilitation training. By contracting the muscles of the injured limb, blood circulation in the tissues around the fracture can be increased, promoting fracture healing and preventing muscle atrophy. Furthermore, by actively or passively moving the unfixed joints, joint adhesions can be prevented, thereby enabling the injured limb to recover as quickly as possible.

[0003] Current mainstream lower limb fracture rehabilitation training devices are mostly limited to single leg-kicking or leg-raising movements, lacking comprehensive equipment that can integrate these two core training methods simultaneously. This makes it difficult to meet the needs of patients for comprehensive rehabilitation. In the leg-kicking training, existing devices generally use a weighted block design to apply pressure. This not only requires frequent adjustment of the weighted blocks to suit the training intensity of different patients, but also lacks an effective safety protection mechanism in case of sudden accidents during training. It is impossible to stop training in time or buffer the impact force, which may cause secondary injury to the injured area. In terms of leg-raising training, the training methods of existing devices are relatively monotonous and lack an entertaining design that can motivate patients. Long-term training can easily lead to fatigue and resistance in patients, making it difficult to stick to regular training and thus affecting the rehabilitation effect. Therefore, those skilled in the art have proposed a rehabilitation training device for patients with lower limb fractures. Summary of the Invention

[0020] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the invention. The objectives of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations may be made without departing from the stated principles.

[0021] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0022] Example 1: As attached Figure 1 To be continued Figure 8 As shown, this invention provides a rehabilitation training device for patients with lower limb fractures, including a lying board 1. Electric guide rails 2 are provided on both the front and rear sides of the lying board 1. The electric guide rails 2 drive corresponding extension plates 3 to slide along their length. A shaft 4 is rotatably connected between the two extension plates 3 via bearings. A rotating plate 5 is fixedly connected to the middle of the shaft 4. A comprehensive training unit 6 is provided on the outer side of the rotating plate 5. The comprehensive training unit 6 moves on the top left side of the lying board 1 via the electric guide rails 2. A lying posture adjustment unit 7 is provided on the top right side of the lying board 1. An adjustment motor 8 for driving the shaft 4 to rotate is fixedly installed on the outer side of the extension plates 3. The comprehensive training unit 6 includes a housing 601 fixedly connected to the rotating plate 5, a leg-pressing module 602, and a leg-raising module 606. The leg-pressing module 602 includes a basic leg-pressing component 603, an adjustment module 604 for adjusting the leg-pressing resistance, and a protection module 605 for timely termination of training. The leg-raising module 606 includes a basic leg-raising component 607 and an enhancement component 608 for increasing the enjoyment of the leg-raising exercise.

[0023] As described above, the patient lies on top of the reclining board 1, and the lumbar region is raised through the reclining adjustment unit 7 to adapt to the training posture. Then, the electric guide rail 2 drives the extension plate 3 to slide along its length, moving the integrated training unit 6, which is connected to the extension plate 3 via the shaft 4 and the rotating plate 5, to the upper side of the patient's legs. Next, the adjustment motor 8 is activated, driving the shaft 4 to rotate. The shaft 4 drives the rotating plate 5 and the integrated training unit 6 to rotate synchronously until the integrated training unit 6 tilts to a suitable angle for the patient to exert force with their legs. The patient places their feet on the outside of the pedal 6038 of the leg-pressing module 602, and exerts force with both feet to press the pedal 6038, completing the leg-pressing rehabilitation movement through the leg-pressing basic component 603. Furthermore, based on the resistance requirements of patients at different stages of rehabilitation (early, middle, and late), the resistance of the leg-raising base component 603 can be adjusted by the adjustment module 604. If unexpected situations such as pain or weakness occur during leg-raising training, the patient can activate the protection module 605 through the external controller to immediately stop the movement of the leg-raising base component 603, thereby avoiding accidents. In addition, the patient can place both feet on the foot pedals 6073 of the leg-raising module 606 and complete the training action of frequently raising both legs through the leg-raising base component 607. When the leg-raising base component 607 moves, it will be linked with the fun-enhancing component 608 to drive the fan 6088 to rotate and blow air on the patient, thereby enhancing the fun of leg-raising training.

[0024] Example 2: As attached Figure 3 To be continued Figure 4 As shown, this embodiment is basically the same as the previous embodiment, except that the leg-mounting base component 603 includes connecting plates 6031 fixedly connected to both sides of the housing 601, a guide rod 6032 fixedly connected between the two connecting plates 6031, the guide rod 6032 penetrating the housing 601, and sliders 6033 slidably connected to the guide rod 6032 on opposite sides of the housing 601. A connecting rod 6034 is hinged to the side of each slider 6033 away from the guide rod 6032, and the connecting rod 6034 is away from the slider 6033. One end of each is hinged with an extension block 6035, which extends out of the housing 601 and is fixedly connected to a foot pedal 6038. A dovetail groove 6036 is provided on the outer side of the extension block 6035 along its extension direction. A guide plate 6037 is slidably connected inside the dovetail groove 6036. The guide plate 6037 is fixedly connected to the inner wall of the opening of the housing 601. A thrust spring 6039 is fixedly connected to the outer side of each slider 6033. Through grooves 60310 for the thrust springs 6039 to move are provided on both sides of the housing 601.

[0025] As can be seen from the above, when the patient performs leg-pressing exercises, both feet are placed against the outer side of the pedal 6038 and a pressing force is applied. The pedal 6038 drives the extension block 6035, which is fixedly connected to it, to move away from the opening of the box 601. When the extension block 6035 moves, the dovetail groove 6036 on its outer side slides along the guide plate 6037 fixed to the inner wall of the opening of the box 601, ensuring that the extension block 6035 does not deviate during the movement. At the same time, the extension block 6035 pushes the slider 6033 through the hinged connecting rod 6034. The slider 6033 slides along the guide rod 6032 that runs through the box 601. When the slider 6033 slides, it will compress the thrust spring 6039 that is fixedly connected to its outer side. When the patient releases both feet to step on the pedal 6038, the compressed thrust spring 6039 returns to its original position. The sliders 6033 on both sides slide and return to their original position along the outer side of the guide rod 6032. Then, through the connecting rod 6034, the pedal 6038 extends out of the opening of the box 601 again. Thus, the rehabilitation training of the patient's leg-kicking movement is realized through the continuous linkage of the leg-kicking basic component 603.

[0026] Example 3: As attached Figure 4 As shown, this embodiment is basically the same as the previous embodiment, except that the adjustment module 604 includes an adjustment motor 6041 fixedly installed on the outside of the connecting plate 6031. The output end of the adjustment motor 6041 extends to the inside of the connecting plate 6031 and is fixedly connected to a lead screw 6042. The lead screw 6042 rotates on the outside of the housing 601. An adjustment plate 6043 is threadedly connected to the outside of the lead screw 6042. The adjustment plate 6043 slides on the outside of the guide rod 6032. The end of the thrust spring 6039 away from the slider 6033 is fixedly connected to the adjustment plate 6043.

[0027] As can be seen from the above, when it is necessary to adjust the leg-pushing resistance to suit the patient's rehabilitation stage, the adjusting motor 6041 fixed on the outside of the connecting plate 6031 is activated. The output end of the adjusting motor 6041 drives the lead screw 6042 extending to the inside of the connecting plate 6031 to rotate. Since the adjusting plate 6043 is threadedly connected to the outside of the lead screw 6042, and the adjusting plate 6043 is sleeved on the outside of the guide rod 6032, when the lead screw 6042 rotates, it will drive the adjusting plate 6043 to slide linearly along the guide rod 6032. And because of the thrust spring The end of 6039 away from slider 6033 is fixedly connected to adjusting plate 6043. Sliding adjusting plate 6043 changes the initial compression of thrust spring 6039. When adjusting plate 6043 slides closer to slider 6033, the initial compression of thrust spring 6039 increases, and the leg-pushing resistance increases accordingly. When adjusting plate 6043 slides away from slider 6033, the initial compression of thrust spring 6039 decreases, and the leg-pushing resistance decreases accordingly, thereby achieving precise adjustment of the resistance of the leg-pushing base component 603.

[0028] Example 4: As attached Figure 5 As shown, this embodiment is basically the same as the previous embodiment, except that the protective module 605 includes a cylinder 6051 fixedly installed on the outside of the opening of the housing 601. The driving end of the cylinder 6051 extends into the interior of the guide plate 6037 and is fixedly connected to a connecting rod 6052. The end of the connecting rod 6052 away from the cylinder 6051 is fixedly connected to a card plate 6053. The outer side of the guide plate 6037 is provided with an inlet / outlet groove 6054 for the card plate 6053 to move. The interior of the dovetail groove 6036 is provided with several sets of card slots 6055 linearly and equidistantly arranged along the length direction.

[0029] As can be seen from the above, if an unexpected situation occurs during the leg-kicking training, the patient sends a start signal to the cylinder 6051 of the protection module 605 through the external controller. The driving end of the cylinder 6051 drives the connecting rod 6052 to extend into the guide plate 6037. The locking plate 6053 moves with the connecting rod 6052 and extends to the outside of the inlet / outlet slot 6054, thereby locking the locking plate 6053 into the slot 6055. The movement of the extension block 6035 is restricted by mechanical locking, thereby stopping the movement of the connecting rod 6034 and the slider 6033. Finally, the leg-kicking basic component 603 is stopped in an emergency, avoiding secondary impact on the injured part of the patient.

[0030] Example 5: As attached Figure 6 As shown, this embodiment is basically the same as the previous embodiment, except that the leg-raising base component 607 includes a rotating rod 6071 rotatably connected to opposite sides of the housing 601. One end of the rotating rod 6071 is fixedly connected to a connecting plate 6072. The outer side of the connecting plate 6072 is rotatably connected to a foot pedal 6073 via a pin. The fun-enhancing component 608 includes a transmission wheel 6081 fixedly connected to the outer side of the rotating rod 6071. The transmission wheel 6081 is connected to a transmission wheel 6083 via a belt 6082. The transmission wheel 6083 is fixedly connected to a bevel gear 6085 via a transmission rod 6084. The outer side of the bevel gear 6085 is meshed with a bevel gear 6086. The bevel gear 6086 is detachably connected to a fan 6088 via a transmission rod 6087. Both the transmission rod 6084 and the transmission rod 6087 rotate on the outer side of the housing 601 via a support plate 6089.

[0031] As can be seen from the above, when performing leg-raising exercises for the patient, both feet are placed on the foot pedal 6073, and then the patient exerts force to lift both legs upward, causing the foot pedal 6073 and the connecting plate 6072 to rotate synchronously. The rotating rod 6071 rotates with the connecting plate 6072 on opposite sides of the housing 601. When the rotating rod 6071 rotates, the transmission wheel 6081 fixed on its outer side rotates synchronously. The transmission wheel 6081 drives the transmission wheel 6083 to rotate through the belt 6082. The transmission wheel 6083 drives the transmission rod 6084 to rotate. 081 then drives the bevel gear 6085 at its end to rotate. The rotation of bevel gear 6085 causes bevel gear 6086 and the transmission rod 6087 fixed thereto to rotate. The fan 6088, which is detached from the transmission rod 6087, rotates with the transmission rod 6087, generating airflow and blowing it on the patient, thereby increasing the fun of leg-raising training. Since the transmission rod 6087 and the fan 6088 are detached, different toys can be connected to the transmission rod 6087 according to the patient's requirements, thereby further improving the entertainment value of the device.

[0032] Example 6: As attached Figure 7 To be continued Figure 8 As shown, this embodiment is basically the same as the previous embodiment, except that the lying posture adjustment unit 7 includes a frame 701 fixedly connected to the top of the lying board 1. A ramp 702 is provided on the side of the frame 701 and the lying board 1 near the comprehensive training unit 6. A threaded rod 703 is rotatably connected inside the frame 701. An adjustment motor 704 is fixedly installed on the outside of the frame 701. The output end of the adjustment motor 704 extends into the inside of the frame 701 and is fixedly connected to one end of the threaded rod 703. Two sets of guide rods 705 are also fixedly connected inside the frame 701. The two sets of guide rods 705 are symmetrically distributed on opposite sides of the threaded rod 703. A movable block 706 is threadedly connected to the outside of the threaded rod 703. The movable block 706 moves along the two... The guide rod 705 slides on the outside. Two sets of connecting parts 707 are provided on the upper side of the movable block 706. One set of connecting parts 707 is located on the top of the movable block 706. A lying plate 709 is hinged to the outside of the frame 701. The other set of connecting parts 707 is located at the bottom of the lying plate 709. The two sets of connecting parts 707 are connected by a transmission plate 708. The connecting part 707 includes two rings 7071. A rotating rod 7072 is rotatably connected between the two rings 7071. The two rings 7071 in one set of connecting parts 707 are fixedly connected to the top of the movable block 706. The two rings 7071 in the other set of connecting parts 707 are fixedly connected to the bottom of the lying plate 709. The two sets of rotating rods 7072 are respectively fixedly connected to both ends of the transmission plate 708.

[0033] As can be seen from the above, when the patient needs to raise their waist to adjust their lying position, the adjustment motor 704 fixed on the outside of the frame 701 is activated. The output end of the adjustment motor 704 extends into the frame 701 and drives the threaded rod 703 to rotate. The rotation of the threaded rod 703 drives the movable block 706 to slide linearly along the guide rod 705. When the movable block 706 slides, it drives the transmission plate 708 to move through the connector 707. The two sets of rotating rods 7072 rotate relative to each other in their respective two rings 7071. Then, the transmission plate 708 pushes the lying board 709 to rotate upward around the hinge of the frame 701 to raise the patient's waist. The ramp 702 also adapts to the transition between the patient's body and the lying board 709 and the lying board 1, avoiding hard friction between the patient's body and the equipment and improving the comfort of lying down.

[0034] Working principle: The patient lies on top of the reclining board 1, and the lumbar spine is raised by the reclining adjustment unit 7 to adapt to the training posture. Then, the electric guide rail 2 drives the extension plate 3 to slide along its length, which moves the integrated training unit 6, which is connected to the extension plate 3 through the shaft 4 and the rotating plate 5, to the upper side of the patient's legs. Then, the adjustment motor 3 8 is started, driving the shaft 4 to rotate. The shaft 4 drives the rotating plate 5 and the integrated training unit 6 to rotate synchronously until the integrated training unit 6 is tilted to a suitable angle for the patient's leg strength. When the patient performs leg-pressing exercises, both feet are placed against the outer side of the pedal 6038 and a pressing force is applied. The pedal 6038 drives the extension block 6035, which is fixedly connected to it, to move away from the opening of the box 601. As the extension block 6035 moves, the dovetail groove 6036 on its outer side slides along the guide plate 6037 fixed to the inner wall of the opening of the box 601, ensuring that the extension block 6035 does not deviate during the movement. At the same time, the extension block 6035 pushes the slider 6033 along the through-hole via the hinged connecting rod 6034. When the guide rod 6032 of the box 601 slides, the slider 6033 will compress the thrust spring 6039 fixedly connected to its outer side. When the patient releases the pedal 6038 with both feet, the compressed thrust spring 6039 returns to its original position, and the sliders 6033 on both sides slide back to their original position along the outer side of the guide rod 6032. Then, the pedal 6038 is extended out of the opening of the box 601 again through the connecting rod 6034. Thus, the rehabilitation training of the patient's leg kicking action is realized through the continuous linkage of the leg kicking basic component 603. When it is necessary to adjust the leg-pushing resistance to suit the patient's rehabilitation stage, the adjusting motor 6041, fixed to the outside of the connecting plate 6031, is activated. The output end of the adjusting motor 6041 drives the lead screw 6042, which extends to the inside of the connecting plate 6031, to rotate. Since the adjusting plate 6043 is threadedly connected to the outside of the lead screw 6042 and is sleeved on the outside of the guide rod 6032, the rotation of the lead screw 6042 will cause the adjusting plate 6043 to slide linearly along the guide rod 6032. Furthermore, due to the thrust spring 60... The end of 39 away from the slider 6033 is fixedly connected to the adjusting plate 6043. The sliding of the adjusting plate 6043 will change the initial compression of the thrust spring 6039. When the adjusting plate 6043 slides towards the slider 6033, the initial compression of the thrust spring 6039 increases, and the leg-pushing resistance increases accordingly. When the adjusting plate 6043 slides away from the slider 6033, the initial compression of the thrust spring 6039 decreases, and the leg-pushing resistance decreases accordingly, thereby achieving precise adjustment of the resistance of the leg-pushing base component 603. If an unexpected situation occurs during the leg-kicking training, the patient sends a start signal to the cylinder 6051 of the protection module 605 through the external controller. The drive end of the cylinder 6051 drives the connecting rod 6052 to extend into the guide plate 6037. The locking plate 6053 moves with the connecting rod 6052 and extends to the outside of the inlet / outlet slot 6054, thereby locking the locking plate 6053 into the slot 6055. The movement of the extension block 6035 is restricted by mechanical locking, thereby stopping the movement of the connecting rod 6034 and the slider 6033. Finally, the leg-kicking basic component 603 is stopped in an emergency, avoiding secondary impact on the injured part of the patient. When performing leg-raising exercises for the patient, both feet are placed on foot pedals 6073. The patient then lifts their legs upwards, causing foot pedals 6073 and connecting plate 6072 to rotate synchronously. Rotating rod 6071 rotates with connecting plate 6072 on opposite sides of housing 601. As rotating rod 6071 rotates, its outer fixed transmission wheel 6081 rotates synchronously. Transmission wheel 6081 drives transmission wheel 6083 to rotate via belt 6082. Transmission wheel 6083 drives transmission rod 6084 to rotate. It also drives the bevel gear 6085 at its end to rotate. The rotation of the bevel gear 6085 causes the bevel gear 6086 and the transmission rod 6087 fixed thereto to rotate. The fan 6088, which is detached from the transmission rod 6087, rotates with the transmission rod 6087, generating airflow and blowing it on the patient, thereby increasing the fun in leg raising training. Since the transmission rod 6087 and the fan 6088 are detached, different toys can be connected to the transmission rod 6087 according to the patient's requirements, thereby further improving the entertainment value of the device. When a patient needs to elevate their lower back to adjust their lying position, the second adjusting motor 704, fixed to the outside of the frame 701, is activated. The output end of the second adjusting motor 704 extends into the frame 701 and drives the threaded rod 703 to rotate. The rotation of the threaded rod 703 causes the movable block 706 to slide linearly along the second guide rod 705. When the movable block 706 slides, it drives the transmission plate 708 to move through the connector 707. Both sets of rotating rods 7072 rotate relative to each other within their respective two rings 7071. In turn, the transmission plate 708 pushes the lying board 709 to rotate upward around the hinge of the frame 701, thereby elevating the patient's lower back. The ramp 702 also adapts to the transition between the patient's body and the lying board 709 and the lying board 1, avoiding hard friction between the patient's body and the equipment and improving lying comfort.
