Description

Technical Field

[0001] The present invention relates to the technical field of walkers, in particular to an adjustable walker for orthopedic rehabilitation. Background Art

[0002] Patients often need the help of various assistive devices to improve their quality of life and rehabilitation efficiency during recovery after surgery or injury. These assistive devices not only need to provide adequate support, but also need to adapt to individual differences in patients, including but not limited to factors such as height, weight, injury site and severity. Although traditional walkers have been on the market for a long time and have helped many patients, they are usually fixed in design, lack flexibility, and cannot meet the needs of different patients well. In addition, the use of traditional walkers often limits the patient's range of motion and reduces their opportunities to participate in daily activities, which to some extent affects the patient's recovery process.

[0003] In some existing walker designs, a significant problem is that the fixing mechanism of the rollers is not perfect. When the user needs to stop to talk to others or perform other short-term activities, the walker may move due to a slight external force because the rollers cannot be effectively locked. This may not only cause the position of the walker to shift, but more seriously increase the risk of the user falling. This problem is particularly prominent for elderly people with limited mobility or patients undergoing rehabilitation, because they often need more stability to ensure safety. Another factor that limits the practicality of existing walkers is the inconvenience of height adjustment. Each user has different physical conditions and needs, and a walker that can adapt to a variety of heights is obviously more ideal. However, the height adjustment of many walkers on the market is either too complicated in design and time-consuming and laborious to operate; or there is no height adjustment function at all, which greatly reduces the applicability and user experience of the product. Based on this, the present invention designs an adjustable walker for orthopedic rehabilitation to solve the above problems. Summary of the invention

[0004] The object of the present invention is to provide an adjustable walker for orthopedic rehabilitation to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

The lifting mechanism includes an electric telescopic rod, an L-shaped abdominal rod, and an iron plate. When a patient needs to use the device for exercise, the medical staff needs to adjust it according to the patient's height and press the fixed rod to press the fixed rod out of the fixed groove. At this time, the electric telescopic rod is started, and the electric telescopic rod drives the L-shaped abdominal rod to be lifted and adjusted. After the L-shaped abdominal rod is lifted to an appropriate height, the pressure on the fixed rod is released. At this time, the fixed rod enters the fixed groove through the cooperation of the second spring and the movable block, and the L-shaped abdominal rod is fixed by the cooperation of the second spring and the fixed groove.

[0017] 3. The present invention can achieve rest for patients through the coordinated use of the electric retracting rod, polyester fiber cloth and fixator. After a long period of exercise, patients often need proper rest to avoid accidents caused by overwork. When patients feel tired and need to rest, they can easily pull out the polyester fiber cloth from the inside of the discharge port. The polyester fiber cloth runs through the strip-shaped through-slot and is firmly positioned by the fixator. In this way, the polyester fiber cloth can provide a stable support point for patients, so that they can sit or lean safely during exercise and get the necessary rest.
