Description

Technical Field

[0001] This utility model relates to the field of leg rehabilitation equipment technology, and more particularly to wearable walking aids, especially a wearable weightless walking aid for the lower leg and ankle. Background Technology

[0002] After an injury to the lower leg or ankle, it is usually necessary to avoid weight-bearing to promote the recovery of soft tissue or fractures. Currently, the most common assistive devices are crutches or wheelchairs. When using crutches, the patient needs to hold the cane with one or both hands, thus not freeing up their hands. Wheelchairs are more cumbersome and less portable.

[0003] Currently available single-leg walking aids typically only allow for length adjustment, not width adjustment. This can negatively impact comfort for individuals with larger or smaller builds, making them unsuitable for wearing. Furthermore, the thigh section of these aids is often connected via fabric, leather, and straps, resulting in a relatively weak overall frame structure. Under rotational and shearing forces, this can lead to structural deformation.

[0004] Similar walking aids lack effective rigid support after being fixed to the thigh, which can lead to problems such as loosening of the thigh fixation, device displacement and rotation, and poor comfort during walking activities.

[0005] Currently, no effective solutions have been proposed for the problems existing in related technologies, such as poor wearing comfort, difficulty in wearing, poor structural stability, and easy deformation of the structure when subjected to rotational shear forces. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing a wearable mobility aid device that solves problems such as poor wearing comfort, difficulty in wearing, poor structural stability, and easy deformation of the structure when subjected to rotational shear forces.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A wearable mobility aid device, comprising: The first side support unit has an adjustable height. A second side support unit is symmetrically arranged with the first side support unit, and the height of the second side support unit is adjustable. A bottom connecting unit is disposed between the first side support unit and the second side support unit, and is connected to the first side support unit and the second side support unit respectively. The width of the bottom connecting unit is adjustable and is used to cooperate with the first side support unit and the second side support unit to form a stable frame structure.

[0008] In some of these embodiments, it also includes: At least one anterior thigh limiting unit, the two ends of which are respectively connected to the top of the first side support unit and the top of the second side support unit, for defining the anterior side of the patient's thigh region.

[0009] In some of these embodiments, it also includes: At least one posterior thigh restraint unit, the two ends of which are respectively connected to the top end of the first side support unit and the top end of the second side support unit, for defining the posterior side of the patient's thigh region.

[0010] In some of these embodiments, it also includes: At least one anterior lower leg limiting unit, the two ends of which are respectively connected to the middle of the first side support unit and the middle of the second side support unit, for defining the anterior side of the patient's lower leg region.

[0011] In some of these embodiments, it also includes: At least one posterior knee joint limiting unit, the two ends of which are respectively connected to the middle of the first side support unit and the middle of the second side support unit, for defining the posterior side of the patient's knee joint region.

[0012] In some of these embodiments, it also includes: At least one thigh cushioning unit is provided, which is disposed between the top of the first side support unit and the top of the second side support unit, for cushioning the patient's thigh area.

[0013] The present invention adopts the above technical solution and has the following technical effects compared with the prior art: This utility model discloses a wearable walking aid device with adjustable lengths for the first and second side support units to accommodate people with different leg lengths. The bottom connecting unit connects the first and second side support units into a stable frame structure, which can better support the weight of the human body. The adjustable width design of the bottom connecting unit can be adjusted according to the leg size of different patients, thus expanding the scope of application. Attached Figure Description
