Abstract
Description
Technical Field
[0001] This utility model relates to an auxiliary device, specifically an auxiliary device for rehabilitation and nursing care of prosthetic patients. Background Technology
[0002] Prostheses are artificial limbs specially manufactured and fitted to compensate for limb loss and lost limb function in amputees. Rehabilitation assistive devices for prostheses refer to various appliances and equipment designed and used to help prostheses patients better adapt to their prostheses, restore bodily functions, and improve their quality of life. Before fitting a prosthesis, patients generally have experienced injury, such as to the upper arm, and require assistive devices to help the upper arm recover as much as possible. Currently, upper arm assistive devices are generally forearm slings, which are tubular structures that suspend and fix the forearm. This structure cannot be properly adjusted according to the user's arm, especially its curvature and length, making it unsuitable for preventing or correcting upper arm deformities. It cannot provide adequate support, stability, fixation, and protection for the upper arm, making it difficult to adapt to the prosthesis and even exacerbating the pain and discomfort caused by amputation. Utility Model Content

The main upper arm fixation sleeve, the main forearm fixation sleeve, the secondary upper arm fixation sleeve and the secondary forearm fixation sleeve are each provided with a notch on the back, and an adjustable strap for binding on the arm is provided at the notch. A telescopic plate is fixed through the front side of the secondary upper arm fixation sleeve, one end of the telescopic plate is inserted into a telescopic slot in the front side wall of the main upper arm fixation sleeve, and a sliding locking block for fixing the telescopic plate of the secondary upper arm fixation sleeve is provided in the front side wall of the main upper arm fixation sleeve. The telescopic plate fixed by the secondary forearm fixation sleeve is inserted into a telescopic slot in the front side wall of the main forearm fixation sleeve, and a sliding locking block for fixing the telescopic plate of the secondary forearm fixation sleeve is also provided in the front side wall of the main forearm fixation sleeve.
[0005] The rotating structure includes a hollow rotating shell and an adjusting disc that is rotatably supported at one end inside the rotating shell. One end of the rotating shell is fixedly connected to one end of the telescopic plate of the auxiliary upper arm fixing sleeve. The outer side wall of one end of the adjusting disc of the rotating shell is cylindrical and is provided with a long strip groove around the cylinder. One end of the telescopic plate of the auxiliary forearm fixing sleeve passes through the long strip groove and is fixedly connected to the side wall of the adjusting disc. The surface of the rotating shell is provided with a locking structure for locking the adjusting disc.
[0006] Furthermore, the sliding lock block is slidably disposed in the sliding opening on the front side of the auxiliary upper arm fixing sleeve and the auxiliary forearm fixing sleeve. Inclined guide grooves are provided on the two side walls of the sliding opening. The sliders fixed on both sides of the sliding lock block are respectively located in the guide grooves on each side. When the sliding lock block is pushed to one end of the sliding opening, the inner side of the sliding lock block is used to press the telescopic plate.
[0007] Furthermore, the locking structure includes a sliding push plate and a fixed plug provided at the locking end of the sliding push plate. The sliding push plate is slidably disposed in a groove on the front side of the rotating housing. Multiple locking holes are evenly arranged on the outer side wall of the adjusting turntable. A spring structure is provided at the other end of the sliding push plate. The spring structure pushes the fixed plug of the sliding push plate into the locking hole.
[0008] Furthermore, the front sidewall of the rotating housing is provided with an arc-shaped opening arranged around the center of the rotation axis of the adjusting turntable, and a pointer that slides within the arc-shaped opening is fixed on the surface of the adjusting turntable. An angle scale line is provided on the front sidewall of the rotating housing inside the arc-shaped opening.
[0009] Furthermore, the inner surfaces of the main upper arm fixing sleeve, the main forearm fixing sleeve, the secondary upper arm fixing sleeve, and the secondary forearm fixing sleeve are each provided with a soft inner lining structure, and the inner lining structures of the main upper arm fixing sleeve and the secondary upper arm fixing sleeve are connected together.
[0010] Furthermore, a circular protective pad is provided on the inner surface of the rotating structure.
[0011] Furthermore, the inner side of the sliding lock block is also provided with a layer of anti-slip rubber that directly contacts the telescopic plate.
[0012] Furthermore, a hook for securing the strap is provided on one side wall of the main forearm fixing sleeve.
[0013] Furthermore, the adjusting turntable is rotatably connected to the rotating housing by a pin that passes through the adjusting turntable and the rotating housing, and the two ends of the pin are respectively fixed with baffles for limiting the position.
[0014] In use, the main upper arm fixing sleeve and the auxiliary upper arm fixing sleeve are respectively fitted onto the upper arm and secured, while the main forearm fixing sleeve and the auxiliary forearm fixing sleeve are respectively fitted onto the forearm and secured. The length of the telescopic plate inserted into the telescopic slot can be adjusted to regulate the length between the upper arm fixing sleeve and the auxiliary upper arm fixing sleeve, and between the main forearm fixing sleeve and the auxiliary forearm fixing sleeve, thereby better adapting to the different upper arm and forearm lengths of different users. The bending angle of the upper arm and forearm is adjusted by the locking structure. By pushing the sliding push plate and the fixing plug away from the locking hole, the adjusting dial can rotate inside the rotating housing. After rotating to the appropriate position, the sliding push plate is released, and the spring structure pushes the fixing plug of the sliding push plate back into the locking hole, thereby locking the adjusting dial and better securing the forearm according to the user's needs.
[0015] The main upper arm fixation sleeve, main forearm fixation sleeve, auxiliary upper arm fixation sleeve, and auxiliary forearm fixation sleeve of this utility model can fully fix the upper arm and forearm. The main upper arm fixation sleeve and auxiliary upper arm fixation sleeve, as well as the main forearm fixation sleeve and auxiliary forearm fixation sleeve, are fixedly connected by a telescopic plate. This not only provides high fixation strength and stability, but the telescopic plate can also be adjusted for telescopic extension, making it more adaptable. In addition, it is convenient to adjust the bending angle between the upper arm and forearm during fixation, better adapting to the characteristics of the user's arm. It plays a good role in supporting and stabilizing, fixing and protecting, preventing and correcting deformities, inhibiting spasticity, and reducing axial load. It can help users better adapt to the prosthesis, reduce pain and discomfort caused by amputation, enhance the patient's self-image at work, and assist in completing more operational activities.
