Description

Technical Field

[0001] The utility model relates to an adaptive walking aid for orthopedic rehabilitation, specifically an adaptive walking aid for orthopedic rehabilitation, belonging to the technical field of walking aids. Background Technique

[0002] A walking aid, also called a lower limb orthosis, is a walking support tool used by the elderly with inconvenient mobility, certain trauma patients, hemiplegic patients and the disabled. It can assist the human body to support the weight, maintain balance and exercise walking.

[0003] By supporting the walking aid with both hands, the walking aid supports the human body to assist the legs in walking, supports the walking of the legs, and gradually rehabilitates the patients undergoing orthopedic rehabilitation.

[0004] During the training process, by changing the supporting force of both hands, the support of the legs to the whole body is changed, and the legs are gradually restored until they can walk completely without relying on the support of both hands and can rely on the legs to walk. However, in the prior art, during the rehabilitation training process, the supporting force of both hands completely depends on human judgment, and its supporting force cannot be intuitively displayed, resulting in completely relying on human feeling when using the walking aid for rehabilitation training, and it is easy to have situations such as excessive support of the legs or poor rehabilitation training effect. Therefore, we propose an adaptive walking aid for orthopedic rehabilitation. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] An embodiment of the present utility model discloses an adaptive walking aid for orthopedic rehabilitation.

[0023] According to the attached Figures 1-3 As shown, it includes a bottom support frame 1. A pulley 2 is fixedly connected to the bottom of the bottom support frame 1, which facilitates the movement of the bottom support frame 1. An upper support frame 4 is arranged above the bottom support frame 1. A first connecting rod 3 is fixedly connected between the bottom support frames 1. A second connecting rod 401 is fixedly connected between the upper support frames 4. An armrest is arranged on the upper support frame 4 to facilitate the support of the user. The upper support frame 4 is provided with:

[0024] A buffer unit. The buffer unit includes a threaded rod 5 and a buffer spring 501. The threaded rod 5 is slidably connected to the inner wall of the upper support frame 4. The bottom end face of the threaded rod 5 is fixedly connected to the bottom support frame 1. The buffer spring 501 is sleeved on the outer peripheral wall of the threaded rod 5. The buffer unit is used to buffer the upper support frame 4. When both hands support on the upper support frame 4, at this time, the upper support frame 4 is pushed to slide along the threaded rod 5. Under the movement of the upper support frame 4, the buffer spring 501 is compressed. Under the rebound of the buffer spring 501, the human body is buffered and supported.

[0025] A positioning unit. The positioning unit includes a fixed seat 6, a positioning seat 7 and a moving rod 601. The fixed seat 6 is fixedly connected to the second connecting rod 401. The moving rod 601 is fixedly connected to the first connecting rod 3. The positioning seat 7 is slidably connected to the outer peripheral wall of the moving rod 601. The positioning unit positions the supporting force of the upper support frame 4 on the person through the positioning seat 7. When the upper support frame 4 moves, the fixed seat 6 on the second connecting rod 401 is driven to move. At this time, the fixed seat 6 moves along the moving rod 601, pushing the positioning seat 7 to slide. Through the position of the positioning seat 7 on the moving rod 601, it is convenient to observe the supporting force of both hands, and the auxiliary force of both hands can be intuitively found, which is convenient for subsequent plan adjustment and avoids the situation of excessive support of both legs or poor rehabilitation training effect.

[0026] An adjusting nut 503 is threadedly connected to the outer peripheral wall of the threaded rod 5. By rotating the adjusting nut 503, the adjusting nut 503 rotates along the outer peripheral wall of the threaded rod 5.

[0027] The top end face of the adjusting nut 503 is rotatably connected to a sliding seat 502. Under the rotation of the threaded rod 5, the sliding seat 502 slides along the threaded rod 5.

[0028] The top end face of the sliding seat 502 is fixedly connected to a buffer spring 501. At this time, the threaded rod 5 compresses the buffer spring 501, changing the supporting force of the buffer spring 501 on the upper support frame 4 to meet the usage requirements of different patients.

[0029] When both hands support on the upper support frame 4, at this time, push the upper support frame 4 to slide along the threaded rod 5. When the upper support frame 4 moves, drive the fixed seat 6 on the second connecting rod 401 to move. At this time, the fixed seat 6 moves along the moving rod 601;

[0030] Push the positioning seat 7 to slide. Through the position of the positioning seat 7 on the moving rod 601, it is convenient to observe the supporting strength of both hands, and it is possible to intuitively find the assisting strength of both hands, which is convenient for subsequent plan adjustment and avoids the situation of excessive support of both legs or poor rehabilitation training effect.

[0031] A sliding rod 701 is slidably connected to the inner wall of the positioning seat 7. The end of the sliding rod 701 is fixedly connected to an extrusion seat 702, and the extrusion seat 702 is attached to the outer peripheral wall of the moving rod 601.

[0032] An extrusion spring 703 is sleeved on the outer peripheral wall of the sliding rod 701. When the user does not use the upper support frame 4, under the rebound of the buffer spring 501, push the upper support frame 4 to return to the starting position. At this time, under the rebound of the extrusion spring 703, the extrusion seat 702 is in close contact with the moving rod 601 to ensure the stability of the positioning seat 7 and the moving rod 601.

[0033] One end of the extrusion spring 703 is fixedly connected to the inner wall of the positioning seat 7, and the other end of the extrusion spring 703 is fixedly connected to the outer wall of the extrusion seat 702. Through the position of the positioning seat 7 on the moving rod 601, the maximum supporting strength of both hands can be intuitively observed, and then the training plan can be adjusted.

[0034] In addition, it should be understood that although this specification is described according to the embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
