Technical Field

[0001] The utility model relates to the technical field of rehabilitation equipment, in particular to a limb function movement rehabilitation device for sequelae of cerebrovascular disease. Background Art

[0002] Most of the sequelae of cerebrovascular disease will cause movement disorders, hemiplegia, limb nerve compression and numbness, etc., and patients usually need to undergo postoperative care and appropriate exercise.

[0003] Most of the existing sports rehabilitation equipment commonly used for the sequelae of cerebrovascular disease are made of steel structures, including a base and a seat for patients to sit on. Usually, two horizontal slide rails of different heights are connected to the top of the base, and sliders are slidably connected in the two slide rails. The two upper sliders are fixedly connected with handles for patients to hold, and the two lower sliders are provided with leg baffles to achieve opening and closing training of the patient's hands and legs. The patient usually sits on the seat of the equipment, grasps the handle part of the equipment with his hands, and the two calves are respectively in contact with the two leg baffles of the equipment, and the limb movement training is achieved by horizontally opening and closing the arms and legs. At the same time, the existing handle part and leg support will also be provided with damping, so that the patient can achieve advanced strength training to restore the body's motor function.

[0004] Although existing equipment can enable patients to achieve limb movement and strength training, it is still difficult to effectively relieve limb numbness during rehabilitation training. The nerves in the patient's limbs are compressed by the blood and remain numb, and they still need to rely on external force or patting to relieve symptoms such as numbness. Utility Model Content

The number of the plurality of connecting columns is the same as the number of the sliders and the plurality of racks are fixedly connected to the sliders one by one. The slide rail is provided with a through groove in the vertical direction, the number of the plurality of racks is the same as the number of the slide rails and the plurality of racks are fixedly connected to the through grooves in the horizontal direction one by one. Each rack is meshed with two gears, a fixed disk is fixedly sleeved under the wheel axle of the gear, a plurality of impact rods are connected to the fixed disk along its circumference, the impact rods can be elastically retracted and are used for colliding with the corresponding connecting columns during the rotation of the fixed disk, each wheel axle is connected to the adjacent connecting column through a connecting piece, and is used for driving the wheel axle to move synchronously and in the same direction when the connecting column is displaced with the slider.

[0007] Preferably, the impact rod includes a cylinder with an opening on one side and a sliding rod slidably connected to the cylinder. One end of the sliding rod placed in the cylinder is fixedly connected to a first spring. The first spring is fixedly connected to the inner wall of the cylinder. When the first spring is in an initial state without extension and contraction, the sliding rod can collide with the connecting column when the outer end of the sliding rod approaches the connecting column.

[0008] Preferably, the end of the sliding rod placed in the cylinder is connected to an anti-slip flange, and the diameter of one side of the opening of the cylinder is smaller than the anti-slip flange.

[0009] Preferably, the connecting member is a thin-walled plate, which is located below the corresponding slide rail, the wheel axle vertically penetrates the connecting member and the two are rotationally connected, and the other end of the connecting member is fixedly connected to the connecting column.

[0010] Preferably, a distance is left between the other side of each gear and the inner wall of the corresponding through slot.

At this time, the gear will rotate after meshing with the rack on one side, and the rotation of the gear will drive the wheel axle to rotate synchronously in the same direction along the connecting piece, so that the fixed plate and multiple impact rods will also rotate. By limiting the elastic expansion and contraction of the impact rod, when the impact rod approaches the connecting column, the impact rod will collide with the connecting column for the first time, and vibration force will be generated in this process, and the vibration force will be directly transmitted to the handle held by the patient, so as to achieve the effect of vibration in the process of limb exercise, and rely on the vibration force to relieve the symptoms of upper limb numbness, and the same is true for the legs.

[0027] A specific implementation of the present utility model is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present utility model is not limited by the specific implementation mode.

[0028] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the technical solution of the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0029] refer to Figure 1 , Figure 2 and Figure 5 The utility model provides a limb function exercise rehabilitation device for sequelae of cerebrovascular disease, including two slide rails 3 fixedly connected to the top of the base 1 and a slider 4 slidably connected to the slide rails 3, and also includes: a plurality of connecting columns 7 and a plurality of racks 8. The number of the plurality of connecting columns 7 is the same as the number of the sliders 4, and they are fixedly connected to each slider 4 one by one. The slide rail 3 is vertically provided with a through groove 31, and the number of the plurality of racks 8 is the same as the number of the slide rails 3, and they are horizontally fixedly connected to the through groove 31 one by one. Each rack 8 is meshed with two gears 9. A fixed disk 11 is fixedly sleeved below the wheel axle 10 of the gear 9. The fixed disk 11 is connected to a plurality of striker rods 12 along its circumference. The striker rod 12 can be elastically retracted and used for colliding with the corresponding connecting column 7 during the rotation of the fixed disk 11. Each wheel axle 10 is connected to the adjacent connecting column 7 through a connecting piece, and is used for when the connecting column 7 is displaced with the slider 4, the connecting piece drives the wheel axle 10 to move synchronously and in the same direction.

[0030] In the above embodiments, the slider 4 is arranged to slide along the sliding groove of the slide rail 3. When the patient holds the handle 5 and extends the leg into the leg baffle 6 to perform opening and closing training, for example, the two upper connecting columns 7 will slide along the slide rail 3 to both sides or towards each other along with the slider 4 corresponding to the handle 5, and the axle 10 connected to the connecting column 7 through the connecting piece and the gear 9 fixedly connected to the axle 10 will also move synchronously. At this time, the gear 9 will rotate after meshing with the rack 8 on one side, and the rotation of the gear 9 will drive the axle 10 to move synchronously in the same direction along the connecting piece. The rotation of the fixing plate 11 and the plurality of impact rods 12 also causes the rotation. By limiting the impact rod 12 to be elastically retractable, when the impact rod 12 approaches the connecting column 7, the impact rod 12 will collide with the connecting column 7 for the first time. Vibration force will be generated in this process, and the vibration force is directly transmitted to the handle 5 held by the patient, so as to achieve the effect of vibration in the process of limb exercise, and rely on the vibration force to relieve the numbness of the upper limbs, and the same is true for the legs. The numbness of the limbs can be relieved in the process of rehabilitation training to achieve opening and closing of the limbs.

[0031] Further, refer to Figure 8 The impact rod 12 includes a cylinder 121 with an opening on one side and a sliding rod 122 slidably connected to the cylinder 121. One end of the sliding rod 122 placed in the cylinder 121 is fixedly connected to a first spring 123. The first spring 123 is fixedly connected to the inner wall of the cylinder 121. When the first spring 123 is in an initial state without extension and contraction, the sliding rod 122 can collide with the connecting column 7 when the outer end of the sliding rod 122 approaches the connecting column 7.

[0032] When the wheel axle 10 continues to rotate, the sliding rod 122 will slide into the cylinder 121 and squeeze the first spring 123, so that the sliding rod 122 passes over the connecting column 7. At this time, the next striking rod 12 will also approach the connecting column 7 and collide with it, thereby repeatedly forming multiple sections of uninterrupted vibration force. Whether the vibration force is frequent depends on the number of striking rods 12. When the number is large, the frequency of collision is also high, and the vibration efficiency is relatively good. Of course, it cannot be too many, which is not only costly but also unnecessary. Therefore, it is preferred that 4-6 striking rods 12 are evenly distributed on each fixed disk 11. Of course, when the sliding rod 122 approaches the connecting column 7, its end will contact the adjacent side of the connecting column 7. The maximum length of the sliding rod 122 extending outward will not exceed the radius of the connecting column 7 when it is adjacent to the connecting column 7, thereby avoiding the side wall of the sliding rod 122 from being stuck with the connecting column 7.

[0033] Further, refer to Figure 8The end of the sliding rod 122 placed in the cylinder 121 is connected with an anti-slip flange, and the diameter of the opening side of the cylinder 121 is smaller than the anti-slip flange.

[0034] In the above embodiments, the anti-dropping flange has an anti-dropping effect on the sliding rod 122 .

[0035] Further, refer to Figure 4 , Figure 5 and Figure 7 The connecting piece is a thin-walled plate, which is located below the corresponding slide rail 3. The wheel axle 10 vertically penetrates the connecting piece and the two are rotationally connected. The other end of the connecting piece is fixedly connected to the connecting column 7.

[0036] Further, refer to Figure 5 A distance is left between the other side of each gear 9 and the inner wall of the corresponding through groove 31 .

[0037] Further, refer to Figure 2 , Figure 3 and Figure 6 The portion of the connecting column 7 corresponding to the collision of the collision rod 12 is provided with a noise reduction cotton sleeve 13.

[0038] In the above embodiments, the noise reduction cotton sleeve 13 is provided to reduce the noise generated when the impact rod 12 hits the connecting column 7 as much as possible. The noise reduction cotton sleeve 13 can be a thin cotton sleeve or a thicker cotton sleeve, depending on the actual noise reduction effect. At the same time, the connecting column 7 part located at the noise reduction cotton sleeve 13 is made of solid steel.

[0039] Further, refer to Figure 5 and Figure 8 The end of the sliding rod 122 outside the cylinder 121 is connected to a block having an outer arc surface and made of metal.

[0040] In the above embodiments, the block is limited to an arc shape, which can facilitate it to easily squeeze over the connecting column 7 after colliding with the connecting column 7. Preferably, the block can also be replaced with a roller with a metal outer wall, and the axis of the roller extends vertically, so that the roller can pass over the connecting column 7 faster and smoothly.

[0041] Further, refer to Figure 5 , Figure 6 and Figure 7 The slide rail 3 is arranged in a semi-arc shape, and the through groove 31 and the rack 8 adapt to and match the shape of the slide rail 3.

[0042] In the above embodiments, since the patient's arms and legs form an arc-shaped trajectory when they are spread out to both sides, by limiting the slide rail 3 to be set in a semi-arc shape, it can adapt to the ergonomics of the patient's training process and be more suitable for the patient's rehabilitation training, thereby improving the training effect.

[0043] Further, refer to Figure 2 and Figure 3 The lower ends of the two upper connecting columns 7 are fixedly connected to the upper ends of the two lower connecting columns 7.

[0044] In the above embodiments, by limiting the lower ends of the two upper connecting columns 7 to be fixedly connected to the upper ends of the two lower connecting columns 7, synchronous training of the legs and arms can be achieved. When it is difficult for the arms to exert force, the legs can assist in training the arms. At the same time, when the arms are mainly trained, the legs can be detached to increase the intensity of the arm training.

[0045] Further, refer to Figure 3 , and also includes a plurality of second springs 14, which are sequentially arranged in each slide rail 3 so that the two handles 5 and the leg baffle 6 have reverse impedance when moving.

[0046] Specifically, the two second springs 14 are respectively fixedly connected to the two sides of the upper two sliders 4, and a stopper is provided in the middle of the slide rail 3 to prevent the two sliders 4 from being close to each other so that the two groups of impact rods 12 collide, and the two second springs 14 are respectively fixedly provided between the stopper and the two sliders 4.

[0047] The two leg baffles 6 are fixedly connected to the two connecting columns 7 below in a one-to-one manner. The two vertical leg baffles 6 are arranged in an open arc shape, and the opening faces one side of the seat 2. The horizontal distance between the two leg baffles 6 and the seat 2 is greater than the distance between the handle 5 and the seat 2, and can be extended by an L-shaped turning rod or the like. This specific implementation method is an existing conventional means, and this device does not make specific structural limitations and displays.

[0048] The above disclosures are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
