Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to an adjustable upper limb support device. Background Technology

[0002] Postoperative recovery from upper limb fractures, upper limb weakness due to nerve damage, and the need for upper limb support and elevation during bed rest are all beneficial for the patient's recovery. However, currently available upper limb support and elevation devices generally have some insurmountable problems.

[0003] The main disadvantages of existing electric upper limb support mechanisms are: High price: Relying on complex components such as motors, reducers, and control systems, the manufacturing cost is high, resulting in expensive products. This makes them unaffordable for most ordinary families and hinders widespread adoption. High barrier to entry: Operation usually relies on a control panel, which is not user-friendly for elderly patients or those with mobility impairments. Furthermore, electric devices require a power source, limiting their use in certain scenarios and posing certain safety risks. Size and maintenance: The devices are relatively large, taking up a lot of space, making them unsuitable for small home environments. Electrical components also increase the failure rate and maintenance costs, making them unsuitable for long-term home use.

[0004] The main drawbacks of existing fixed support mechanisms are: Lack of adjustability: The angle and height are fixed, making it impossible to adjust according to the patient's rehabilitation stage, training movements, or personal comfort. Poor applicability: Patients require different support angles at different stages of rehabilitation. Fixed designs often only meet a single need, resulting in limited functionality and practicality. Summary of the Invention

[0005] Based on the shortcomings of existing upper limb support devices in the background art, this utility model proposes an adjustable upper limb support device. This application has a simple structure, is purely mechanically adjustable, and is easy to operate.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An adjustable upper limb support device includes a fixed base, a base mounted on the fixed base, a cross-turning plate mounted on the base, a lower end of an upper arm rod connected to the cross-turning plate, and an upper end of an upper arm rod connected to a forearm rod via a hinge. The upper arm rod can rotate on the cross-turning plate. A fixed support plate and a Velcro strap fastener are mounted on the upper arm rod and the forearm rod.

[0007] Furthermore, the fixed base is an L-shaped plate.

[0008] Furthermore, the base is circular and has an arc-shaped bolt groove, through which bolts are installed on the fixed base.

[0009] Furthermore, the cross steering plate consists of a pair of semi-circular guide plates, each with a semi-circular groove. The upper arm is mounted in the pair of semi-circular guide plates via a pin, and the locking handle drives the upper arm to rotate and brake longitudinally within the semi-circular groove of the cross steering plate.

[0010] Furthermore, the upper arm and the forearm arm are hinged together by a lockable movable hinge.

[0011] Furthermore, the fixing plate is arc-shaped, and a strap is installed on the Velcro fastener.

[0012] The above technical solution can achieve the following beneficial effects: This invention adopts a purely mechanical structure without complex electronic or hydraulic components, resulting in a low failure rate and long service life. It features a simple and reliable structure. By adjusting the longitudinal rotation of the shoulder joint on the forearm bar and the lateral rotation of the elbow joint on the upper arm bar, this invention can achieve multi-angle fixation to meet the elevation needs at different stages, achieving flexible angle adjustment. No professional personnel are required for operation; patients or their families can independently complete the angle adjustment and fixation, making it suitable for home rehabilitation. It has the advantages of convenient operation, low cost, and the mechanical structure design reduces manufacturing costs, which is conducive to its widespread application.

[0019] The present invention will be further described below with reference to the accompanying drawings: like Figure 1-5As shown, an adjustable upper limb support device includes a fixed base 1, which is an L-shaped plate. A base 2 is mounted on the fixed base 1. The base 2 is circular and has an arc-shaped bolt groove 11. Bolts 10 pass through the arc-shaped bolt groove and are mounted on the fixed base 1. A cross-turning plate 3 is fixed to the base by bolts. The cross-turning plate 3 consists of a pair of semi-circular guide plates. The semi-circular guide plates have a semi-circular arc groove 12. An upper arm rod 4 is mounted in the pair of semi-circular guide plates by a pin 14. A locking handle 13 drives the upper arm rod to achieve longitudinal rotation and braking of the shoulder joint within the semi-circular arc groove 12 of the cross-turning plate. The upper end of the upper arm rod 4 is connected to the forearm rod 6 by a lockable movable hinge 5. The upper arm rod 4 rotates on the cross-turning plate 3. A fixed support plate 7 and a Velcro fastener 8 are mounted on the upper arm rod 4 and the forearm rod 6. The fixed support plate 7 is arc-shaped, and a strap is mounted on the Velcro fastener 8.

[0020] Fixed base installation: The fixed base is made of metal and is L-shaped with an anti-slip rubber pad attached to the bottom. The base 2 is fastened to the preset installation position of the fixed base 1 with bolts. The base 2 has four evenly distributed arc-shaped bolt slots 11, which allows for fine-tuning installation.

[0021] Angle adjustment component assembly: Fix the cross steering plate 3 to the top of the base 2, and then connect the upper arm rod 4 to the cross steering plate 3 through the pin 14 and the locking handle 13. The longitudinal rotation function of the shoulder joint is realized by rotating the upper arm rod 4. Install the lockable movable hinge 5 on the upper arm rod 4, and then assemble the forearm rod 6 with the lockable movable hinge 5 to complete the construction of the elbow joint rotation structure.

[0022] Upper limb support installation: Fix the arc-shaped fixed support plate 7 with sponge padding and the Velcro fastener 8 to the corresponding positions of the upper arm rod 4 and the forearm rod 6 with screws respectively; add Velcro straps to the Velcro fastener 8 (not shown in the figure, additional configuration required).

[0023] Clinical use implementation Preparation stage: Confirm that the fixed base 1 is placed on a flat surface and that the anti-slip pad is fully in contact with the contact surface to ensure the stability of the mechanism.

[0024] Angle Adjustment: Turn the locking handle counterclockwise to loosen the latch, adjust the angle between the cross steering plate 3 and the upper arm bar 4 to suit the patient's comfortable shoulder joint position, and turn the locking handle clockwise to tighten the latch. Loosen the latch of the lockable hinge 5, adjust the angle between the forearm bar 6 and the upper arm bar 4 to match the patient's elbow flexion and extension needs, and then lock the hinge.

[0025] Patient arm fixation: Assist the patient to place their arm into the fixation plate 7, and adjust the tightness using the straps on the Velcro fastener 8 to ensure that the arm fits snugly against the plate without any pressure, and to prevent slippage.

[0026] The above method of use is for raising or training one affected limb. If it is for bilateral patients, two sets of raising devices can be set up, that is, two fixed bases 1 can be set up accordingly.

[0027] The above descriptions are all preferred embodiments of this utility model. For those skilled in the art, any modifications to this utility model in various equivalent forms without departing from the principle of this utility model shall fall within the protection scope of the appended claims.
