Description

Technical Field

[0001] The utility model relates to a fracture fixing device, in particular to a device used for fixing ulna and radius fractures in a hand-raising upright position. Background Art

[0002] Ulna and radius fractures are common upper limb fractures, accounting for approximately 17% of all fractures. They occur most frequently in the elderly and are more common in women. The healing process of radius and ulna fractures often results in localized swelling, with peak swelling occurring 24 to 72 hours after injury. In severe cases, tension blisters may develop, hindering surgical intervention. Fractures can cause severe damage to forearm muscles and blood vessels, leading to severe soft tissue swelling and compartment syndrome. Failure to mobilize the uninjured distal joint early can lead to tendon adhesions and contractures, joint stiffness, muscle atrophy and weakness, and osteoporosis. This can prolong recovery of wrist function, even incomplete recovery, and can also lead to neurovascular disorders. Therefore, timely and effective nursing care is crucial for early relief of swelling and pain in patients with radius and ulna fractures.

[0003] Immobilization after surgery for ulna and radius fractures in the elderly can increase bone resorption, inhibit osteogenesis, further exacerbate osteoporosis, and, in severe cases, cause refracture. Therefore, early functional training is crucial for osteoporotic fracture healing. Early, active functional training can reduce intra-articular adhesions, tendon and muscle adhesions, and contractures, effectively preventing joint stiffness and promoting functional recovery. Functional training can also accelerate metabolism and promote absorption of exudates within tissues, thereby reducing tissue swelling, accelerating osteogenesis, and promoting callus formation.

[0004] Fracture healing often presents with complications such as limited wrist rotation, pain, tendon contracture, decreased grip strength, stiffness, and malunion, severely impacting patients' activities of daily living. In addition to proper reduction and fixation, the treatment of radial fractures requires scientific and rational clinical nursing interventions to promote a speedy recovery.

[0005] Currently, slings made of bandages or other materials are used clinically to elevate the upper limb by applying force to the neck and shoulders. However, this method has drawbacks such as high arbitrariness, uncertain elevation height, and easy slippage. Furthermore, because the sling's small force-bearing area can easily cause soreness in the neck and shoulder muscles, many patients abandon the upper limb suspension midway, directly impacting wound healing and functional recovery. While patients are in the supine position, a pillow is often used to elevate the affected limb to reduce swelling. However, the elevation range is small, the limb lacks stability, and the height of the affected limb can easily change, resulting in ineffective swelling reduction and poor comfort.

[0006] For patients with ulna and radius fractures, the standard approach is to elevate the affected limb while standing or sitting. This involves using a bandage or scarf to flex the elbow of the immobilized upper limb 90 degrees and place it against the chest. For patients in the supine position, a standard approach is to use an upper limb elevation pad to reduce swelling. Utility Model Content

[0007] In order to solve the above-mentioned deficiencies in the prior art, the utility model provides a device for fixing ulna and radius fractures in a hand-raised upright position, comprising a fixing strap, a fixing frame and a retaining belt.

[0008] The fixed straps include a waist and abdomen belt and two shoulder straps. The waist and abdomen belt is used to be fixed to the waist and abdomen of the human body, and the shoulder straps are used to go around the shoulders of the human body and the two ends are respectively connected to the waist and abdomen belts corresponding to the abdomen and back of the human body. The fixing frame includes a first fixing part and a second fixing part that are fixedly connected. The first fixing part is provided with a first fixing belt that can be opened and closed, and the second fixing part is provided with a second fixing belt that can be opened and closed. The first fixing belt and the second fixing belt are respectively used to connect the first fixing part and the second fixing part to the upper arm and forearm of the human body. The first fixing part and the second fixing part are perpendicular to each other, so that the upper arm and forearm of the human body remain vertical. The retaining belt is detachably connected to the first fixing part and the waist and abdomen belt, and is used to maintain the fixed hand-raising posture when lying down. The retaining belt is also detachably connected to the second fixing part and the top position of the two shoulder straps, and is used to maintain the fixed hand-raising posture when standing or sitting.

[0009] To use the device, put on the brace and secure the frame to the patient's arm with the ulnar and radial fracture using the first and second straps, ensuring the patient's upper and lower arms are vertical. When the patient is recumbent, connect the retaining straps to the first mounting section and the waist and abdomen straps, aligning the patient's upper arms parallel to the longitudinal axis of the body and their lower arms perpendicular to the bed. When the patient is standing or sitting, connect the retaining straps to the second mounting section and the tops of the two shoulder straps, aligning the patient's lower arms parallel to the longitudinal axis of the body. This allows the patient to maintain a consistent, upright, "hands-up" position.

[0010] Furthermore, a hand-shaped groove is provided on the second fixing portion at a position corresponding to a human hand.

[0011] Furthermore, a third fixing belt is provided on the second fixing part at a position corresponding to the hand-shaped groove, and a detachable handgrip dynamometer is provided on the third fixing belt, so that the patient can see the daily changes in the grip strength of the affected limb and increase his confidence in overcoming the disease.

[0012] Furthermore, the second fixing belt is provided with a detachable ice pack, which facilitates the patient's swelling of the affected limb before and after surgery.

[0013] Furthermore, the second fixing belt is provided with a net bag which is detachably mounted on the second fixing belt and is used for mounting the ice pack.

[0014] Furthermore, the retaining belt includes a first retaining belt, a second retaining belt and a third retaining belt; the first retaining belt is used to detachably connect the first fixing part and the waist and abdomen belt; the second retaining belt is used to detachably connect the second fixing part and the top position of the shoulder strap corresponding to the shoulder on the side close to the second fixing part; the third retaining belt is used to detachably connect the second fixing part and the top position of the shoulder strap corresponding to the shoulder on the side away from the second fixing part.

[0015] Furthermore, the waist and abdomen belt is provided with a first connecting buckle, and the two shoulder straps are provided with a second connecting buckle at the top position; the first fixing part is provided with a third connecting buckle, and the second fixing part is provided with a fourth connecting buckle and a fifth connecting buckle; the first retaining belt is detachably connected to the first connecting buckle and the third connecting buckle, and the second retaining belt and the third retaining belt are detachably connected to the second connecting buckle and the fourth connecting buckle or the fifth connecting buckle.

[0016] Furthermore, it also includes a fourth retaining belt; the first retaining belt is used to detachably connect the first fixing part and the waist and abdomen belt corresponding to the abdomen position of the human body; the fourth retaining belt is used to detachably connect the first fixing part and the waist and abdomen belt corresponding to the back position of the human body.

[0017] Furthermore, a first connecting buckle is provided at a position of the waist and abdominal belt corresponding to the abdomen of the human body; a sixth connecting buckle is provided at a position of the waist and abdominal belt corresponding to the back of the human body; a seventh connecting buckle is also provided on the first fixing part, and a fourth retaining belt is used to detachably connect the sixth connecting buckle and the seventh connecting buckle.

[0018] Furthermore, two sets of fixation frames are provided, corresponding to the left and right arms of the human body, and an appropriate fixation frame is selected according to the patient's fractured arm.

[0019] Clinically, it has been found that when patients are walking or resting in bed, the affected limb is positioned in an upright "hand-raised" position. Specifically, the patient adopts a "hand-raised" position, with the ulna and radius parallel to the longitudinal axis of the body when standing or sitting, and perpendicular to the bed when lying. This position is more conducive to reducing swelling and pain, and facilitates postoperative functional training and recovery. This utility model can accelerate patient recovery and improve bed turnover in the department. BRIEF DESCRIPTION OF THE DRAWINGS
