Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary devices, and specifically refers to a novel shoulder joint fixation device. Background Art

[0002] The shoulder joint is one of the joints with the largest range of motion in the human body, and its health status has an important impact on an individual's daily life and motor ability. However, most of the existing shoulder joint braces adopt a single fixation method, which is difficult to meet the specific needs of different patients. Especially, they are not flexible and convenient enough in the fixation and stability of the shoulder joint, and are difficult to be adjusted according to different treatment or recovery stages, which is not conducive to the recovery of users.

[0003] At the same time, traditional braces use non-breathable materials, which are likely to cause skin discomfort after long-term wearing, and even lead to complications such as pressure sores and ulcers. In addition, the weight and hardness of the braces will also increase the wearing burden of patients and affect daily activities. Some braces lack a convenient adjustment mechanism and cannot quickly adapt to the changes during the treatment process of patients, reducing the use efficiency and patient satisfaction. Some braces need to be removed during elbow joint functional exercises, increasing the pain and inconvenience of patients. The brace structure is not reasonably designed, and patients cannot wear it independently and need the assistance of others, which limits the self-care ability of patients. In case of emergency, medical staff need to spend more time on adjustment and fixation, affecting the treatment efficiency.

[0004] In order to overcome the above defects, the present invention provides a novel shoulder joint fixation device, which provides a more scientific, efficient and comfortable treatment and rehabilitation solution for patients through innovative structural design and material selection.

This multi-angle adjustment function ensures reliability and safety in various treatment and rehabilitation scenarios, helps to maintain the correct treatment position, and improves the rehabilitation effect.

[0047] 6. Reduce maintenance costs

[0048] Modular design: The present invention adopts a modular design, and each component is easy to replace. The selected materials all meet national standards, ensuring the reliability and safety of the product. This design not only facilitates maintenance and replacement but also reduces the long-term operation and maintenance costs.

[0049] 7. Improve the patient's self-care ability

[0050] Ease of use and comfort design: Due to the ease of use and comfort design of the present invention, patients can more easily wear and adjust the brace by themselves, reducing the dependence on others' assistance and improving the patients' self-care ability.

[0051] 8. Strong adaptability

[0052] Personalized adjustment function: The design of the present invention allows for fine-tuning according to the specific needs of different patients, with broad adaptability and being applicable to patients of different body types and treatment stages. The Velcro connection mechanism of the upper arm fixing device 1 and the lower arm fixing device 2, as well as the adjustment of the strap length of the shoulder fixing device 1 and the shoulder fixing device 2, enable the device to better adapt to individual differences.
