Description

Technical Field

[0001] The utility model relates to a rehabilitation device in the technical field of medical care, in particular to a wearable walking rehabilitation device. Background Art

[0002] Limited lower limb motor ability is the most common functional disorder after stroke, and it is often the first symptom, which seriously affects the patient's walking function and self-care ability in daily activities. The walking rehabilitation stage of stroke patients generally includes three periods. 1. Pre-rehabilitation: Most patients at this stage are bedridden and cannot move to the equipment by themselves. Medical staff are generally needed to help patients to support the equipment. The equipment is a bed-type, and patients can lie or stand for gait training. 2. Mid-rehabilitation: Most patients at this stage can move to the equipment by themselves in a wheelchair. Some walking training will be carried out at this stage. The equipment will be equipped with a weight reduction system to provide safety protection for the patient. The exoskeleton device will be equipped with a motor to use external force to make the patient walk. This type of equipment is expensive and difficult to popularize among patients. 3. Late rehabilitation: At this stage, patients are basically at home or have left the bed. The mainstream walking training equipment on the market is mainly large fixed devices, and patients need to go to specific places for gait correction.

[0003] Most of the existing walking rehabilitation training equipment on the market is suitable for patients' training needs in the early and middle stages of rehabilitation. Bed-type training equipment is large in size and has a fixed usage space, while exoskeleton-type training equipment is expensive and not suitable for home training. As mentioned in the patent announcement number "CN221061175U", "The utility model provides an auxiliary walking device, which relates to the technical field of medical rehabilitation equipment, including an auxiliary support frame and an adjustment mechanism, an adjustment mechanism is installed on the inner side of the auxiliary support frame, a support storage box is installed on one side of the auxiliary support frame, and a protective cover is installed on the surface of the auxiliary support frame; when in use, loosen the adjustment knob, move the adjustment bottom shell to an appropriate height, make the fixing hole flush with the limit slot, tighten the adjustment knob to make the adjustment knob enter the limit slot, and the user can adjust the height of the movable seat according to their actual situation. Through the setting of the locking component, when in use, flip the movable seats on the left and right sides upward by ninety degrees, connect the movable seats on the left and right sides through the slot, move the locking bottom plate to the locking slot position, press the locking button, and make the locking button enter the locking slot to prevent the movable seat slot connection from being unstable, thereby preventing the user from falling when sitting down to rest." For another example, the patent publication number "CN221045175U" mentions that "the utility model discloses a walking training device based on cerebral palsy rehabilitation, including a support frame, a protective frame fixedly connected to the top of the support frame, a hand brake mechanism provided on the surface of the protective frame, a universal wheel rotatably connected to the rear side of the bottom of the support frame, a support plate fixedly connected to the front side of the bottom of the support frame, a mounting shaft rotatably connected between the two support plates, and both ends of the mounting shaft penetrate the support plates and extend to both sides of the two support plates. The utility model relates to the field of rehabilitation training technology. The walking training device based on cerebral palsy rehabilitation, through the setting of the hand brake mechanism, when the limit rod rotates, the limit rod is engaged with the teeth of the limit tooth ring under the action of the first spring to limit the angle of the adjustment tube, so as to avoid the brake pad from resetting. Even if the adjustment tube is released, the device can still maintain the brake stop state, which can not only meet the actual needs of the patient's rehabilitation training, but also reduce the safety hazards when the device is used."

[0004] Therefore, currently, it usually only meets the needs of patients in the middle stage of rehabilitation. At this stage, the patient's gait is unbalanced during walking and needs to use supportive and movable assistive devices. In the middle and late stages of rehabilitation, the patient can walk on his own, but his gait is in an abnormal posture and he needs to use wearable assistive devices to meet his actual needs of rehabilitation training. Summary of the invention

[0005] In order to solve the technical problem that the valgus movement of the thigh on the affected side of the patient cannot be effectively suppressed during walking training, the utility model provides a wearable walking rehabilitation device, which uses rigid constraints to bind the patient's affected side and the normal side of the body. During the patient's walking training, the rigid constraints can effectively limit the valgus movement of the leg on the affected side of the body, and the gait is effectively corrected.

[0006] The utility model is implemented by the following technical scheme: a wearable walking rehabilitation device, which includes: a hip restraint bracket, which is used to restrain the user's buttocks; two thigh outer restraint brackets, which are respectively used to restrain the user's thighs on both sides. The hip restraint bracket includes two swivel supports that are parallel and symmetrically arranged, and three wire rods that are parallel and connected to the two swivel supports; the two swivel supports are both fan-shaped, and the center of the circle rotates to connect the two thigh outer restraint brackets, and the three wire rods are arranged on the fan arc to restrain the user's lower waist, the back of the buttocks and the upper back of the thigh from top to bottom; the three wire rods are arranged in a three-link fan-shaped layout on the two fan-shaped swivel supports to form a rigid constraint with a concave constraint space between the two thigh outer restraint brackets to inhibit the user's thighs from everting on both sides.

[0007] As a further improvement of the above solution, three wire rods are positioned at two sector arcs in an interlaced manner.

[0015] As a further improvement of the above solution, each sector-shaped slewing support is an integrally formed structure.

[0016] The utility model relies on a uniquely designed hip restraint bracket: a three-link fan-shaped layout form of three wire rods on two fan-shaped rotating supports constitutes a rigid constraint forming a concave constraint space between two thigh outer restraint brackets to restrain the user's thighs from everting on both sides, solving the technical problem that existing wearable walking rehabilitation devices cannot effectively restrain the thighs on the affected side of the patient from everting during walking training.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0025] See also Figures 1 to 4 , which is a schematic diagram of the three-dimensional structure of the wearable walking rehabilitation device of the utility model under four viewing angles. The walking rehabilitation device of this embodiment mainly includes a hip restraint bracket 3, two thigh outer restraint brackets 6, a shoulder strap 1, and four leg straps 5. The structural feature of the utility model is: relying on the uniquely designed hip restraint bracket 3, a rigid constraint between the two thigh outer restraint brackets 6 is achieved to form a concave-shaped closed space, which effectively restrains the valgus of the patient's affected leg, and solves the technical problem that the existing wearable walking rehabilitation device cannot effectively suppress the valgus of the patient's affected thigh during walking training.

[0026] The hip restraint bracket 3 is used to restrain the user's hips. The hip restraint bracket 3 includes two swivel supports 32 that are parallel to each other and symmetrically arranged, three wire rods 31 that are parallel to each other and connected to the two swivel supports 32, and may also include six pairs of sliding sleeve positioning rings 33 and at least one pair of auxiliary support members 34.

[0027] Please combine Figure 5 The two rotary supports 32 are both fan-shaped, and the center of the circle 321 is respectively connected to the two outer thigh restraint brackets 6 by rotation. The three wire rods 31 are arranged on the fan arc 322 to restrain the user's lower waist, the back of the buttocks and the upper back of the thigh from top to bottom. The three wire rods 31 are arranged in a three-link fan-shaped form on the two fan-shaped rotary supports 32. This uniquely designed structure forms a rigid constraint with a concave-shaped constraint space between the two outer thigh restraint brackets 6 to inhibit the user's thighs from everting on both sides.

[0028] The three wire rods 31 can be positioned at the two arcs 322 by interlacing, such as three through holes 310 are provided at each arc 34 for the three wire rods 31 to pass through respectively. In order to improve the structural stability between the three wire rods 31 and the corresponding arcs 322, a pair of sliding sleeve positioning rings 33 are arranged relatively with the corresponding arc 322 as the center at each interlacing position of the three wire rods 31 on the arc 322, and the three wire rods 31 are fixed on the two fan-shaped slewing supports 32 by six pairs of sliding sleeve positioning rings 33. The most important purpose of the sliding sleeve positioning ring 33 is to adjust the hip distance, so the sliding sleeve positioning ring 33 is preferably matched with the three wire rods 31 in a clearance. In order to reduce the weight of the wire rod 31 and reduce the weight load of the user, the wire rod 31 can adopt a hollow structure.

[0029] In order to reduce the weight of the swivel support 32 and the weight load of the user, each swivel support 32 can be hollowed out. Of course, it can also be a frame structure as in the present embodiment, but in the present embodiment, the structural design of the swivel support 32 is not only to reduce the weight of the swivel support 32, but more to match the three wire rods 31 to form a three-link fan-shaped layout with a simple structure, separate use, and stable performance. After all, users who wear the walking rehabilitation device of the present invention to walk have inconveniences in walking, so for them, the stable use of the device is the first priority, otherwise it is easy to cause frustration to the user and reduce the customer experience.

[0030] For example, each fan-shaped slewing support 32 may include a center 321 in a circular area, a fan arc 322 in a fan ring, and at least two connecting rods 324 connecting the center 321 and the fan arc 322. In this embodiment, the number of connecting rods 324 is illustrated by taking three as an example. Of course, as long as two of the connecting rods 324 are located at the outermost edges of both sides of the corresponding fan-shaped slewing support 32, the number of connecting rods 324 can be more. The more the number of connecting rods 324 is, the more stable the structure of the corresponding slewing support 32 is, but it also means that the weight of the corresponding slewing support 32 is heavier, which is a heavy burden for the user.

[0031] In order to achieve good rigidity constraint of the concave-shaped constraint space, the connection between each connecting rod 324 and the center 321 and the fan arc 322 is annular, the wire rod 31 and the corresponding fan arc 322 are fixedly connected by inserting in the corresponding annular connection, and the outer thigh constraint bracket 6 and the corresponding center 321 are rotatably connected by setting a rotating shaft 323 to rotate in the corresponding annular connection, thereby preventing the walking rehabilitation device from collapsing and enhancing the user's confidence in the use of the product. In order to further enhance the user's confidence in the use of the product, each fan-shaped swivel support 32 is made into an integral structure as much as possible.

[0032] Please refer again Figure 5The two centers 321 can be respectively connected to the two outer thigh restraint brackets 6 by setting a rotating shaft 323. In this embodiment, a limiting ring 35 is also provided at the center 321 to limit the corresponding outer thigh restraint bracket 6 on the corresponding rotating shaft 323.

[0033] The present invention can also achieve better stability of the walking rehabilitation device of the present invention through at least one pair of auxiliary support members 34. In this embodiment, the number of auxiliary support members 34 is illustrated by taking a pair as an example. The pair of auxiliary support members 34 are symmetrically arranged relative to the two fan-shaped rotary supports 32, and one end of the pair of auxiliary support members 34 is fixed on one of the wire rods 31, and the other end is fixed on the connecting line between the fixed position of the corresponding wire rod 31 on the fan arc 322 and the center of the circle 321. The pair of auxiliary support members 34 can be symmetrically arranged between the two fan-shaped rotary supports 32, and can also be symmetrically arranged on both sides of the two fan-shaped rotary supports 32. If the number of pairs of auxiliary support members 34 is necessary to exceed 1 pair, it is preferred to fix them on each connecting rod 324 as much as possible.

[0034] The strap 1 may include two shoulder straps 11 and a waist strap 12. The two ends of the waist strap 12 may be fixed to the opposite ends of the top wire rod 31, and the waist strap 12 may be used to attach part of the weight of the walking rehabilitation device to the waist. One end of each of the two shoulder straps 11 may be fixed to the opposite ends of the top wire rod 31, and the other end may be fixed to the waist strap 12, and the shoulder straps 11 may be used to attach part of the weight of the walking rehabilitation device to the shoulders.

[0035] The four leg straps 5 can be divided into two groups arranged opposite to each other and fixed on two outer thigh restraint brackets 6 respectively. The upper and lower layers of the two leg straps 5 fixed on the same outer thigh restraint bracket 6 fix the user's thighs. The four leg straps 5 bind the rigid restraint bracket bundle, i.e., the outer thigh restraint bracket 6, to both sides of the thighs. The shoulder strap 1 and the four leg straps 5 can be set in a length-adjustable form so that they can be used by users of different body shapes.

[0036] When the walking rehabilitation device of the utility model is used, the patient wears the walking rehabilitation device, uses the shoulder straps 11 and the waist straps 12 to carry the patient, and the leg straps 5 bind the rigid constraint brackets to the two sides of the thighs. The hip distance is adjusted by the sliding sleeve positioning ring 33. The hip constraint bracket is designed as a three-link form, which corresponds to the lower part of the waist, the back of the hips, and the upper part of the back of the thighs from top to bottom. During walking training, the rigid constraint brackets on both sides (i.e., the two outer thigh constraint brackets 6) and the hip rigid constraint bracket 3 form a concave constraint space, which can effectively inhibit the valgus of the patient's thigh on the affected side.

[0037] The walking rehabilitation device of the utility model mainly relies on rigid constraints to form a concave-shaped closed space, which effectively restrains the eversion of the patient's affected leg. It has the characteristics of being a wearable training device and being lightweight, and thus has a wide range of usage scenarios and is suitable for promotion.

[0038] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model application. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model application shall be based on the attached claims.
