Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to an upper limb joint protection brace for upper limb fractures complicated with nerve damage. Background Technology
[0002] Humeral shaft fractures are common high-energy fractures, and one of the more serious complications is radial nerve injury, which occurs in approximately 10% of cases. Radial nerve injury significantly threatens a patient's daily life and functional recovery. Unfortunately, there is currently a lack of specialized braces designed for humeral shaft fractures complicated by radial nerve injury. While existing treatments aim to address this issue, they still have many limitations.
[0003] Currently, there are two main treatment methods, both aiming to ensure that the elbow and wrist joints remain in a functional position during recovery to promote later functional rehabilitation. The first method involves patients wearing a custom-made cryogenic thermoplastic elbow brace after elbow surgery. This brace is intentionally designed to extend beyond the wrist joint to the distal end of the hand, achieving simultaneous fixation of both the elbow and wrist joints. Specifically, the elbow is fixed at 90°, while the wrist is fixed at 0°. However, this traditional brace design has significant drawbacks: it is bulky and cumbersome, hindering normal elbow movement and severely restricting the range of motion of the wrist and fingers. Over time, this can easily lead to complications such as joint stiffness.
[0004] Another treatment strategy involves wearing a neck-wrist sling to protect the elbow joint post-surgery. Additionally, a separate wrist brace is worn to stabilize the wrist. While this method somewhat avoids restricting elbow movement, allowing for relatively free motion, prolonged wrist immobilization introduces new problems. Because the wrist is fixed for extended periods, finger and wrist flexibility decreases significantly, and stiffness is also likely to occur, negatively impacting the patient's overall recovery process. Utility Model Content
[0005] In view of this, the purpose of this utility model is to overcome the shortcomings in related technologies. This utility model provides an upper limb joint protection brace for upper limb fractures combined with nerve damage.
[0006] This utility model provides the following technical solution:
[0007] An upper limb joint protection brace for upper limb fractures complicated with nerve injury includes an arm support assembly, a sling, and a wrist support assembly.
[0008] The arm support assembly is used to support the patient's fractured arm; the sling is mounted on the arm support assembly and hung on the patient's torso; the wrist support assembly is installed on the side of the arm support assembly near the patient's hand, and the wrist support assembly includes a fixed base and a hand support. The fixed base is connected to the arm support assembly, and the hand support is hinged to the fixed base via a hinge shaft. The hand support is used to support the patient's hand; the fixed base is provided with a limiting member to restrict the relative position of the hand support and the fixed base; the hand support can be deflected relative to the arm support assembly, thereby adjusting the angle between the back of the patient's hand and forearm.
[0009] As a further improvement to the above technical solution, the arm support assembly includes a forearm support and a large arm support, which are connected by a connecting seat. The forearm support is used to support the patient's forearm, and the large arm support is used to provide support for the patient's large arm. The sling and the fixing seat are both connected to the forearm support.
[0010] As a further improvement to the above technical solution, the connecting seat includes a horizontal bar and a vertical bar. The horizontal bar is fixedly connected to the forearm support, and the vertical bar is fixedly connected to the upper arm support. The horizontal bar and the vertical bar are hinged together by a hinge shaft. A limiting member is provided between the horizontal bar and the vertical bar to limit the relative position of the horizontal bar and the vertical bar.
[0011] As a further improvement to the above technical solution, both the forearm support and the upper arm support are loops used to wrap around the patient's arm.
[0012] As a further improvement to the above technical solution, the annular belt is provided with an anti-pressure layer.
[0013] As a further improvement to the above technical solution, both the forearm support and the upper arm support are provided with multiple supports.
[0014] As a further improvement to the above technical solution, the wrist support assembly also includes a finger support corresponding to the patient's fingers. The finger support and the hand support are hinged together by a hinge shaft. The finger support is used to support the patient's fingers. The hand support is provided with a limiting member, which is used to limit the relative position of the finger support and the hand support.
[0015] As a further improvement to the above technical solution, both the hand rest and the finger rest are provided with binding straps, which are used to bind and connect the hand rest or the finger rest to the back of the patient's hand or fingers respectively.
[0016] As a further improvement to the above technical solution, the finger support, the hand support, and the fixing base are arranged in a stacked manner.
[0017] As a further improvement to the above technical solution, the fixed base and the arm support assembly are connected by a connector.
[0018] Compared with related technologies, the beneficial effects of this utility model are:
[0019] The upper limb joint protection brace provided by this utility model for upper limb fractures combined with nerve damage requires, in actual use, firstly, the sling to be hung on the patient's torso, ensuring the sling's position is stable. Then, the patient's arm and wrist joint are placed and fixed onto the arm support assembly and wrist support assembly respectively, thus effectively providing necessary protection and support for the patient's arm and various joints.
[0020] Specifically, the hand support portion of the wrist brace conforms snugly to the back of the patient's hand, ensuring that the brace does not cause discomfort or impair blood circulation during use. Because the hand support and the wrist brace's mounting base are hinged together via a hinge shaft, this connection allows the hand support a degree of flexibility, enabling it to rotate and adjust relative to the mounting base. The mounting base itself is cleverly designed and connected to the arm support assembly, ensuring the stability and reliability of the entire brace structure.
[0021] In practice, medical staff or patients themselves can easily adjust the relative position of the patient's hand and arm by rotating the hand rest relative to the fixed base. This adjustment process is not only simple and convenient, but also allows for adjustment of the wrist joint angle, ensuring that the patient's wrist joint is in the most suitable functional position.
[0022] After adjustment, to further ensure the stability and safety of the brace during use, the relative position of the hand rest and the base can be securely locked using the limiting device on the base. This ensures that the brace remains in the correct position throughout the patient's daily activities and rehabilitation training, effectively providing comprehensive protection for the patient's arm and significantly improving recovery outcomes.

[0034] Combination Figure 1 , Figure 2 As shown, an embodiment of this utility model provides an upper limb joint protection brace for upper limb fractures complicated with nerve damage, including an arm support assembly 100, a sling 200, and a wrist support assembly 300.
[0035] The arm support assembly 100 is used to support the patient's fractured arm. The sling 200 is mounted on the arm support assembly 100 and hung on the patient's torso. The sling 200 can be adjusted to reduce restrictions on the patient's arm joint movement. In the early stages, when the patient's arm joint is significantly swollen, the sling 200 can be lengthened so that the angle between the patient's upper arm and forearm is 100 degrees. As the swelling subsides, the sling 200 can be tightened to 90 degrees. This allows the patient to adjust the sling 200 according to the degree of recovery of the elbow joint angle, thus avoiding excessive restriction of the arm position by the arm support assembly 100, which could lead to elbow joint stiffness.
[0036] The wrist support assembly 300 is installed on the side of the arm support assembly 100 near the patient's hand. The wrist support assembly 300 includes a fixed base 310 and a hand support 320. The fixed base 310 is connected to the arm support assembly 100, and the hand support 320 is hinged to the fixed base 310 via a hinge shaft 430. The hand support 320 is used to support the patient's hand. Specifically, the cooperation between the hand support 320 and the fixed base 310 is used to provide a wrist joint support position 510 for the patient's wrist joint. The fixed base 310 is provided with a limiting member 330, which is used to limit the relative position of the hand support 320 and the fixed base 310. The hand support 320 can be deflected relative to the arm support assembly 100, thereby adjusting the angle between the back of the patient's hand and forearm.
[0037] The upper limb joint protection brace for upper limb fractures complicated with nerve damage provided in this embodiment requires, in actual use, firstly, the sling 200 to be hung on the patient's torso, ensuring the sling 200 is stable. Then, the patient's arm and wrist are placed and fixed onto the arm support assembly 100 and wrist support assembly 300 respectively, thus effectively providing necessary protection and support for the patient's arm and various joints.
[0038] Specifically, the hand support 320 portion of the wrist support assembly 300 conforms to the back of the patient's hand, ensuring that the brace does not cause discomfort or impair blood circulation during use. Since the hand support 320 is hinged to the fixing base 310 of the wrist support assembly 300 via a hinge shaft 430, this connection allows the hand support 320 a degree of flexibility, enabling it to rotate and adjust relative to the fixing base 310. The fixing base 310 itself is connected to the arm support assembly 100 through a mating connection, ensuring the stability and reliability of the entire brace structure.
[0039] In practice, medical staff or patients can easily adjust the relative position of the patient's hand and arm by rotating the hand support 320 relative to the fixed base 310. This adjustment process is not only simple and convenient, but also allows for adjustment of the wrist joint angle, ensuring that the patient's wrist joint is in the most suitable functional position.
[0040] After adjustment, to further ensure the stability and safety of the brace during use, the relative position of the hand support 320 and the fixed base 310 can be securely locked using the limiting member 330 on the fixed base 310. This ensures that the brace remains in the correct position throughout the patient's daily activities and rehabilitation training, effectively providing comprehensive protection for the patient's arm and significantly improving the patient's recovery outcome.
[0041] In some specific embodiments, the arm support assembly 100 includes a forearm support 110 and an upper arm support 120. The forearm support 110 and the upper arm support 120 are connected by a connecting seat 400. The forearm support 110 is used to support the patient's forearm, and the upper arm support 120 is used to support the patient's upper arm. The sling 200 and the fixing seat 310 are both connected to the forearm support 110 to facilitate providing sufficient and reliable support for the patient's arm and improve the recovery effect of the arm.
[0042] In some specific embodiments, the connecting seat 400 includes a horizontal bar 410 and a vertical bar 420. The horizontal bar 410 is fixedly connected to the forearm support 110, and the vertical bar 420 is fixedly connected to the upper arm support 120. The horizontal bar 410 and the vertical bar 420 are hinged together by a hinge shaft 430. A limiting member 330 is provided between the horizontal bar 410 and the vertical bar 420 to restrict the relative position of the horizontal bar 410 and the vertical bar 420. Specifically, when it is necessary to adjust the relative position of the upper arm support 120 and the forearm support 110, it is first necessary to release the restriction of the relative position of the horizontal bar 410 and the vertical bar 420 by a certain operation. Once the limiting member 330 is released, the horizontal bar 410 and the vertical bar 420 can swing relative to each other under the action of the hinge shaft 430. By precisely controlling the angle and range of the swing, the relative position between the upper arm support 120 and the forearm support 110 can be further adjusted, thereby achieving precise adjustment of the static angle between the patient's upper arm and forearm. This adjustment method not only allows the patient's arm to be in a more comfortable and natural rehabilitation position, but also helps to improve the recovery effect of the arm.
[0043] In some specific embodiments, both the forearm support 110 and the upper arm support 120 are loops for wrapping around the patient's arm; this design fully considers the patient's comfort and practical needs during use. The forearm support 110, as a component specifically designed to fit and wrap around the patient's forearm, is made of soft and elastic material, closely conforming to the contour of the forearm without causing excessive pressure. The loop design allows the forearm support 110 to flexibly adapt to forearms of different thicknesses, ensuring stable and comfortable support for the patient.
[0044] Similarly, the upper arm support 120 also appears in the form of a loop, specifically designed to wrap around the patient's upper arm. The loop design of the upper arm support 120 not only considers the stability of the support but also pays special attention to minimizing obstruction of the patient's arm. Traditional arm supports often employ a relatively wide design, easily obstructing most of the arm, which can not only affect the patient's normal activities but also cause discomfort and a feeling of stuffiness. In this embodiment, the upper arm support 120, by using a loop design, greatly reduces obstruction of the arm, allowing the patient to maintain ventilation and comfort during use.
[0045] Furthermore, the forearm support 110 and upper arm support 120 feature a strap design that prioritizes ease of wear and adjustment. The straps are typically equipped with easy-to-use fastening devices such as Velcro or snaps, allowing patients or healthcare professionals to easily put the arm support on their arms and adjust the tightness as needed. This design not only enhances ease of use for patients but also ensures that the arm support maintains stable support throughout its use.
[0046] In some specific embodiments, the ring band includes a pressure-relief layer. As a crucial component of the ring band, this layer's primary function is to reduce pressure on the patient's arm, preventing discomfort or injury during prolonged use. The choice of material for this pressure-relief layer is critical to achieving this goal. Specifically, it can be made from various soft and elastic materials such as a sponge layer or a silicone layer. A sponge layer, a common pressure-relief material, is soft, moderately dense, and has good resilience. When the ring band is wrapped around the patient's arm, the sponge layer conforms closely to the arm's contours, providing adequate cushioning and reducing pressure. Furthermore, the sponge layer offers excellent breathability and moisture absorption, keeping the arm dry and comfortable, preventing stuffiness or dampness after prolonged use. A silicone layer is another high-quality pressure-relief material. Compared to a sponge layer, a silicone layer offers higher strength and durability while maintaining good softness and elasticity. The silicone layer adheres closely to the arm's surface, forming a stable support layer that effectively distributes the pressure on the arm. In addition, the silicone layer has good anti-slip properties, which can ensure that the ring will not shift due to slippage during use, thereby improving the stability and safety of use.
[0047] In some specific embodiments, multiple forearm supports 110 and multiple upper arm supports 120 are provided; the arrangement of multiple forearm supports 110 and multiple upper arm supports 120 not only increases the support area and strength, but also makes the support more evenly distributed, effectively reducing excessive pressure on a single part and improving the patient's comfort.
[0048] Specifically, the forearm support 110 is designed with a sliding adjustment function relative to the crossbar 410. This innovative design allows the forearm support 110 to be flexibly adjusted in position on the crossbar 410 according to the patient's specific body shape and rehabilitation needs. Whether the patient has a slender arm or a more muscular arm, they can find the most suitable support point by sliding the forearm support 110, thereby ensuring the best support effect for the arm.
[0049] Similarly, the upper arm support 120 is also designed to slide and adjust relative to the longitudinal bar 420. This function allows the upper arm support 120 to be adjusted in a personalized manner according to the body characteristics of different patients. By precisely controlling the sliding position of the upper arm support 120 on the longitudinal bar 420, it can be ensured that the upper arm support 120 always conforms to the contour of the patient's upper arm, providing stable and comfortable support for the patient.
[0050] In some specific embodiments, the wrist support assembly 300 further includes a finger support 340 corresponding to the patient's fingers. The finger support 340 is hinged to the hand support 320 via a hinge shaft 430, and the finger support 340 is used to support the patient's fingers. The hand support 320 is provided with a limiting member 330, which restricts the relative position of the finger support 340 and the hand support 320. This design not only enhances the structural stability of the wrist support assembly 300, but also allows the finger support 340 to swing relative to the hand support 320 within a certain range without deviating from its predetermined position. The presence of the limiting member 330 allows medical staff or patients to easily adjust the position of the finger support 340 according to actual needs to adapt to the rehabilitation needs of different patients.
[0051] Specifically, the finger support 340 includes a thumb support 341 and a four-finger support 342. The thumb support 341 corresponds to the shape of the patient's thumb and works in conjunction with the hand support 320 to provide the patient with a thumb metacarpophalangeal joint support position 520. The four-finger support 342 corresponds to the shape of the patient's other four fingers and provides the patient with a four-finger metacarpophalangeal joint support position 530. Through the above settings, it is convenient to provide more fitting and reliable support and protection for the patient's fingers, ensuring the effectiveness of this embodiment.
[0052] It is worth mentioning that the design of the limiting component 330 fully considers the natural flexion and extension angles of the human metacarpophalangeal joints. The normal flexion and extension angle of the metacarpophalangeal joints is generally between 45° and 60°. In this embodiment, the wrist support component 300, by driving the finger support 340 to swing relative to the hand support 320, can easily adjust the patient's metacarpophalangeal joint flexion and extension angle to this functional position. This design not only effectively prevents finger flexion and extension contractures during rehabilitation but also greatly improves safety and rehabilitation effectiveness.
[0053] Furthermore, to more comprehensively meet the rehabilitation needs of patients, a next-level finger support 340 is hinged to the finger support 340 in this embodiment. This design allows the finger support 340 to further restrict and adjust the flexion and extension angles of the patient's interphalangeal joints. The functional flexion and extension angles of normal interphalangeal joints are generally between 80° and 90°. The presence of the next-level finger support 340 allows the wrist support assembly 300 to fix the patient in a functional position during the early stages when muscle strength has not recovered. This function not only helps promote the recovery of the interphalangeal joints but also provides additional support and protection for the patient during rehabilitation, thereby improving the overall recovery effect. In addition, the patient can operate the limiting member 330 in this embodiment using their unaffected hand. This allows the patient to adjust and lock the functional positions of each joint as needed, and also allows the limiting member 330 to be unlocked without removing the embodiment, thus enabling movement of the affected limb and preventing stiffness caused by prolonged fixation of the fingers and wrist, improving the usability of this embodiment.
[0054] In some specific embodiments, both the hand support 320 and the finger support 340 are equipped with binding straps 350, which are used to bind and connect the hand support 320 or the finger support 340 to the back of the patient's hand or fingers, respectively. As a fixing device, the binding straps 350 primarily function to tightly bind the hand support 320 or the finger support 340 to the back of the patient's hand or fingers. This design not only enhances the fit between the hand support 320 and the finger support 340 and the patient's hand, but also effectively avoids the risk of the patient's hand and fingers becoming disengaged from the corresponding hand support 320 or finger support 340 due to accidental movements during rehabilitation. This tight binding connection ensures that the patient's hand and fingers receive stable and continuous support and protection throughout the entire rehabilitation process.
[0055] It's worth mentioning that the design of the 350 binding strap takes patient comfort and user experience into full consideration. Its soft and elastic material conforms closely to the contours of the patient's hands and fingers without causing excessive pressure. Furthermore, the 350 binding strap is typically equipped with easy-to-use fastening devices such as Velcro and snaps, allowing healthcare professionals or patients to easily apply and loosen the strap.
[0056] This design allows patients to perform various rehabilitation exercises with greater peace of mind during the recovery process, without worrying about the dislocation or displacement of their hands or fingers. This not only improves the efficiency and effectiveness of rehabilitation training but also greatly enhances patients' confidence and comfort.
[0057] In some specific embodiments, the finger support 340, the hand support 320, and the fixing base 310 are arranged in a stacked manner. Specifically, the end of the finger support 340 near the hand support 320 is located between the hand support 320 and the back of the patient's hand. This arrangement ensures that the finger support 340 can fit snugly against the patient's fingers without hindering their natural movement. When the finger support 340 needs to be adjusted by swinging, the close connection between the finger support 340 and the hand support 320, and their appropriate position relative to the back of the patient's hand, effectively avoids the risk of reverse strain on the patient's metacarpophalangeal joints. The end of the hand support 320 near the fixing base 310 is located between the fixing base 310 and the patient's arm. This design not only allows the hand support 320 to stably support the patient's palm but also ensures that when the position or angle of the hand support 320 is adjusted, it will not cause unnecessary pressure or strain on the patient's wrist or forearm. The close fit between the hand support 320 and the fixation base 310, along with their proper positioning relative to the patient's arm, provides strong protection and support for the patient's wrist joint.
[0058] In some specific embodiments, the fixing base 310 and the arm support assembly 100 are connected by a connector 311; in this embodiment, the connector 311 can be a common fastener such as a bolt. Bolts, as a standardized connecting element, not only possess high strength and durability, but also allow for a secure connection or easy separation between the fixing base 310 and the arm support assembly 100 through simple tightening or loosening operations. This design allows medical personnel or patients to easily remove or reinstall the wrist support assembly 300 at any time during the rehabilitation process, based on the patient's specific recovery progress and actual needs.
[0059] Furthermore, the design using bolts and other connectors 311 for connection facilitates regular maintenance and inspection of the wrist support assembly 300. Healthcare professionals can easily disassemble the wrist support assembly 300 to clean, disinfect, or replace worn parts, ensuring its continued effectiveness and safety.
