Technical Field
[0001] This utility model relates to the field of rehabilitation tool technology, and in particular to a novel multifunctional upper limb elevation device. Background Technology
[0002] Upper limb fractures are very common in clinical practice, mostly caused by direct or indirect violence. Clinical symptoms include joint pain, swelling, deformity, and abnormal movement. Fracture trauma and postoperative limb swelling not only cause patients unbearable pain, but also slow local blood flow and reduce arterial blood supply after swelling, leading to a lack of nutrients needed for wound repair and delayed wound healing. In addition, due to the anatomical characteristics of the forearm, if the swelling is too severe, it can easily lead to serious complications such as compartment syndrome, affecting the recovery of the fractured limb. Therefore, how to relieve postoperative pain and reduce swelling of fractured limbs has become a hot research topic for clinical nursing staff.
[0003] After an upper limb fracture or joint dislocation, splints are commonly used for temporary fixation to reduce pain during movement. Triangular bandages, slings, or other supports are used to suspend the upper limb in a neutral position with the elbow flexed against the chest, using neck support. However, this method has drawbacks such as inaccurate elbow flexion and shoulder abduction angles, and the sling easily slipping off. The contact area between the triangular bandage or other supports and the neck is too small, which can easily cause neck muscle soreness and discomfort in the affected limb, forcing the patient to stop the suspension midway, thus affecting the healing and functional recovery of the affected limb. The upper limb elevation pad method is mainly used for patients resting in bed. There are many types of elevation pads. Traditionally, upper limb elevation pads are mostly pillows, blankets, and clothing, with pillows being the most widely used. However, they have disadvantages such as easy collapse and deformation, too small elevation angle, and poor swelling reduction effect. In recent years, many researchers have improved them, creating inclined triangular pillows, multifunctional upper limb sponge frames, and combined upper limb elevation pads. However, none of these can be adjusted in height according to the patient's needs and swelling, and patients are prone to fatigue.
[0004] Clinically, upper limbs are mainly elevated using methods such as upper limb elevation pads and upper limb suspension, including headboard supports, multifunctional upper limb sponge frames, and bedside suspension supports. These methods vary in their effectiveness in reducing swelling and providing comfort. However, in practical applications, it has been found that suspension elevation methods elevate the affected limb to a smaller extent and have poor stability, which can easily lead to abnormal twisting and traction of soft tissues. In addition, this method can cause excessive traction force, which can lead to blood pooling, hindering fracture rehabilitation and impeding functional exercises and early recovery of limb function. Therefore, this invention proposes a novel multifunctional upper limb elevation device to address the problems existing in the prior art. Utility Model Content
[0005] To address the aforementioned problems, this utility model proposes a novel multifunctional upper limb elevation device.

[0012] A further improvement is that: the inner side of the pocket has a nylon buckle, and the pocket is bonded to the third sponge body through the nylon buckle; the suspender has a thin sponge pad inside, and the ends of the suspender at both ends are connected and adjusted by Velcro.
[0013] A further improvement is that the first, second, and third sponge bodies are all made of foam sponge, and the foam sponge is wrapped with washed cotton cloth, with zipper stitching on the side.
[0014] Further improvements include: when used in a supine position, the flat end of the first spongy body is placed under the forearm of the affected limb to raise and immobilize the affected limb, while the patient uses an elastic ball for exercise. The second spongy body is connected to the first spongy body to increase the length according to the patient's arm length.
[0015] Further improvements are made in the following ways: When used in a seated or standing position, the first sponge is connected to one end of the top surface of the third sponge, the inclined surface of the first sponge is placed outward between the chest wall and the armpit, the third sponge is placed under the forearm of the affected limb for support, and the diagonal sling around the affected limb is adjusted in length and fixed behind the neck to suspend the forearm while keeping the forearm abducted.
