Description

Technical Field

[0001] The present application relates to the field of rehabilitation medical equipment, and in particular to an adjustable suspension arm support. Background Art

[0002] Currently, in the treatment and rehabilitation process of upper limb diseases such as upper limb fractures, joint dislocations, and brachial plexus injuries, if the injury to the affected limb is more serious, it will cause severe bleeding at the patient's wound. In the early stage of treatment, when the patient needs to lie down, the patient's arm is suspended and raised to reduce bleeding at the patient's wound, while reducing swelling and promoting venous return. While suspending and raising, the patient's affected limb also needs to be fixed and limited, thereby effectively preventing the patient's arm from rotating or moving while lying down, which may affect the patient's recovery. When the patient gets out of bed and moves around, he needs to wear an arm brace with a shoulder strap to facilitate movement and rehabilitation.

[0003] During the rehabilitation process, in order to elevate the patient's affected limb and reduce swelling, medical staff often use pillows or the affected limb to rest on the lower side of the patient's affected limb, or use triangular bandages or cloth bags to suspend and elevate the affected limb, thereby ensuring the patient's comfort as much as possible while reducing bleeding from the wound.

[0004] Regarding the aforementioned technologies, while using pillows or limb support to elevate the affected limb, unconscious movements after falling asleep at night can cause the affected limb to lift off the support. Furthermore, the height of the support cannot be flexibly adjusted according to treatment needs, thus affecting comfort and recovery progress. While using a triangular bandage or cloth bag to suspend the upper limb during ambulance activities can reduce swelling to a certain extent, these methods are difficult to adjust, have a single support point, make it difficult to maintain an effective height for long periods of time, and can easily cause fatigue in the injured limb, shoulder and neck pain, and other problems.

[0034] The embodiment of the present application discloses an adjustable suspension arm support.

[0035] Reference Figures 1 to 4 An adjustable suspension arm support includes a forearm support plate 1, one end of the forearm support plate 1 is hinged to an upper arm support plate 2, an adjustment component for adjusting the position between the forearm support plate 1 and the upper arm support plate 2 is provided between the upper arm support plate 2 and the forearm support plate 1, a suspension fixing buckle 11 is provided at the end of the forearm support plate 1 away from the upper arm support plate 2, a fixing rod 3 is provided in the suspension fixing buckle 11, and a fixing component is provided at the end of the fixing rod 3 away from the suspension fixing buckle 11, and the fixing component is used to fix the fixing rod 3 to other devices, and the upper arm support plate 2 and the forearm support plate 1 are both provided with a strap 12 for fixing the affected limb. Medical staff fix the patient's affected limb in the arm support through the strap 12, and fix the fixing rod 3 to the bedside infusion stand through the fixing component, and then realize the suspension of the entire arm support through the fixing rod 3 and the suspension fixing buckle 11, and finally effectively realize the height-adjustable suspension of the affected limb, thereby reducing bleeding from the patient's wound and accelerating swelling.

[0036] In order to facilitate the separation of the suspension fixing buckle 11 from the fixing rod 3 for patient movement, one side of the suspension fixing buckle 11 is hinged to the lower end surface of the forearm support plate 1, and the other side of the suspension fixing buckle 11 is detachably connected to the lower end surface of the forearm support plate 1. The detachable connection between the suspension fixing buckle 11 and the forearm support plate 1 allows medical personnel to easily remove the fixing rod 3 from the suspension fixing buckle 11, facilitating patient movement and subsequent diagnosis and treatment by medical personnel.

[0037] Since the patient's involuntary movements after falling asleep may pull the arm support, causing the arm support to shake, in order to reduce the shaking of the arm support and strengthen its installation strength, an auxiliary support plate 311 is provided on the side of the fixing rod 3 close to the forearm support plate 1. The auxiliary support plate 311 is fixedly connected to the fixing rod 3. The auxiliary support plate 311 is located on the lower side of the forearm support plate 1. The auxiliary support plate 311 extends along the length direction of the forearm support plate 1, and the auxiliary support plate 311 abuts against the forearm support plate 1. After the installation and connection between the suspension fixing buckle 11 and the forearm support plate 1 are completed, the auxiliary support plate 311 lifts and limits the forearm support plate 1, thereby expanding the stability of the entire arm support.

[0038] The fixing rod 3 comprises an insertion rod 31, a sleeve rod 32, and a positioning pin 35. The insertion rod 31 is connected to the auxiliary support plate 311.
