Description

Technical Field

[0001] The present invention relates to the technical field of walking assistance equipment, and in particular to a multifunctional device for preventing rheumatoid arthritis from falling. Background Art

[0002] Rheumatoid arthritis (RA) is a chronic, systemic disease of unknown etiology, primarily characterized by inflammatory synovitis. It is characterized by polyarticular, symmetrical, and aggressive joint inflammation of the small joints of the hands and feet, often accompanied by extra-articular organ involvement and a positive serum rheumatoid factor, which can lead to joint deformity and loss of function.

[0003] Because rheumatoid arthritis patients are relatively weak and prone to falling, they need devices to assist them when walking. However, the anti-fall walkers currently on the market have relatively simple structures, mainly including two-wheeled, four-wheeled or six-wheeled structures, and are generally large in size and not easy to carry. At the same time, the existing anti-fall walkers cannot be adjusted according to specific circumstances, cannot cooperate well with patients to adjust their strength, and cannot adapt to rehabilitation patients of different heights.

[0004] Therefore, there is an urgent need for a multifunctional device for preventing falls in rheumatoid arthritis to solve the problems of the above-mentioned walkers in various scenarios. Summary of the Invention

[0005] The purpose of the present invention is to provide a multifunctional device for preventing falls for rheumatoid arthritis, which is easy to use and carry, can effectively share the patient's own weight, can support weight-loss gait, and is suitable for use by rheumatoid arthritis patients in different recovery states during walking.

[0006] The embodiment of the present invention is achieved as follows: An embodiment of the present application provides a multifunctional device for preventing rheumatoid arthritis from falling, which includes two side frames and a limiting assembly. The two side frames are hingedly connected by a folding rod. Several connecting belts are provided on the side frames and the folding rod, and the connecting belts are detachably connected to the limiting assembly; the limiting assembly includes a waist limiting part and a leg limiting part, and the leg limiting part includes two limiting ring belts, which are connected by an elastic belt, and the interior of the limiting ring belt is hollow and provided with a filling port.

[0007] In some embodiments of the present invention, the limiting ring belt is arranged in a cylindrical shape, and its radius gradually decreases from top to bottom.

[0008] In some embodiments of the present invention, the side frame includes two support frames and a connecting frame. The two support frames are connected by the connecting frame, and the connecting belt is provided on the support frames; the connecting frame is retractable.

[0009] In some embodiments of the present invention, the waist limiting member includes a waist belt, and a crotch guard is provided on the waist belt.

[0010] In some embodiments of the present invention, a pressure sensor is provided on the crotch guard belt.

[0011] In some embodiments of the present invention, vertical grooves are provided on both sides of the support frame, and an inflatable bag and an inflating mechanism are provided in the vertical grooves.

[0012] In some embodiments of the present invention, the elastic band is provided with a retractable assembly, which includes a retractable cylinder, a drive motor is provided in the retractable cylinder, a retractable plate is provided on the output shaft of the drive motor, and the elastic band is fixedly connected to the retractable plate.

[0013] In some embodiments of the present invention, a rolling wheel is provided at the bottom of the support frame, and a brake pad is provided on one side of the rolling wheel.

[0014] Compared with the prior art, the embodiments of the present invention have at least the following advantages or beneficial effects: Existing anti-fall walkers are difficult to carry, cannot properly accommodate patients' force adjustments, and cannot adapt to rehabilitation patients in different states, resulting in poor adaptability. The present invention provides a multifunctional anti-fall device for rheumatoid arthritis, which includes two side frames and a limiting assembly. The two side frames are hingedly connected by a folding rod. The side frames and the folding rod are provided with a plurality of connecting belts, and the connecting belts are detachably connected to the limiting assembly. The limiting assembly includes a waist limiting member and a leg limiting member. The leg limiting member includes two limiting ring belts, which are connected by an elastic band. The limiting ring belts are hollow inside and provided with a filling port.

[0015] The present invention features waist and leg restraints, which position the patient relative to the device. Two restraint loops provide auxiliary support for the patient's calves and thighs, effectively reducing the load-bearing pressure on the patient's joints, alleviating their burden and facilitating rehabilitation and walking training. Furthermore, the two side frames are hingedly connected by a folding rod, allowing for effective adjustment of the spacing between the two side frames to accommodate different patients, significantly increasing their adaptability. Furthermore, the side frames can be folded together to significantly reduce their footprint, making them easier to carry when not in use.

[0016] The two hinged folding rods allow the operator to fold the side frames together by rotating the hinges of the folding rods, greatly reducing the space occupied by the side frames and making them easy to carry when not in use. The horizontal slider provided on the horizontal chute of the present invention and the limit rod connected thereto can effectively limit the folding rod when the first limit pin is inserted, preventing it from moving unnecessarily. At the same time, the different positions of the horizontal slider on the horizontal chute can effectively adjust the spacing between the side frames on both sides to accommodate different users, greatly increasing its adaptability, ensuring the benign cycle auxiliary maintenance of the patient's leg rehabilitation, and maximizing the care of the patient's leg recovery.
