Abstract
Description
Technical Field
[0001] This invention relates to the field of medical device technology, and specifically to a limb protection device for fall injury care. Background Technology
[0002] Falls are frequent in daily life and work. The lower limbs (especially key areas like the knees and ankles) are the core areas of the body responsible for weight-bearing and movement, making them highly susceptible to fractures, sprains, and soft tissue injuries after a fall. Furthermore, inadequate protection after an injury can easily lead to secondary injuries due to excessive joint movement, external impacts, or unstable immobilization, severely impacting the recovery process. Therefore, limb protection devices after falls have become essential tools for clinical care and home rehabilitation.
[0003] However, existing limb protection devices for fall injury care still have many shortcomings: Limited protection range: Most devices are designed for a single area (such as protecting only the knee joint or fixing only the ankle), and cannot cover key joints of the lower limbs at the same time. They are difficult to meet the needs of multiple falls or injuries requiring coordinated protection, resulting in patients having to wear multiple independent devices, which is cumbersome to operate and has poor adaptability.
[0004] Rigid fixation methods: Existing devices are mostly integral structures that cannot be disassembled or combined, and cannot be flexibly adjusted according to the specific injury site of the patient. For scenarios that only require local protection, the extra structure can easily cause a feeling of restraint, and it is not convenient to clean, replace or repair them separately, resulting in high usage costs.
[0005] Imbalance between fixation effect and comfort: Some devices use rigid materials or are too tight, which can compress local blood vessels and skin, affecting blood circulation and causing discomfort such as stuffiness and itching; while some flexible devices improve comfort, but lack fixation stability, making them easy to shift during patient movement and unable to effectively limit excessive joint movement.
[0006] Insufficient protective performance: The lack of targeted anti-collision buffer design or the use of only a single protective structure makes it difficult to effectively absorb external impact forces and cannot fully avoid secondary collisions that could damage the injured area; at the same time, some devices do not take into account the physiological curves of joints, resulting in poor fit and blind spots in protection.
[0007] Limited functionality: Existing devices only focus on fixation and basic protection, lacking auxiliary rehabilitation functions. For example, they cannot adjust the tightness according to the patient's swelling, nor do they have the function of massage or promoting local blood circulation, which is not conducive to the rapid recovery of the injured area.
[0008] Poor breathability: When worn for a long time, the closed structure design can easily lead to sweat accumulation and heat dissipation, increasing the risk of skin infection. It is especially unsuitable for patients who are bedridden for a long time or need to wear it continuously.
[0009] In view of the defects of the prior art, there is an urgent need for a limb protection device for fall injury care with all-around protection, flexible combination, stable fixation, comfort and ventilation, and auxiliary rehabilitation function to meet the actual needs of clinical care and home rehabilitation and provide reliable protection for the recovery of the injured limb.

[0036] The internal structure cooperation effect.
[0037] The position cooperation of the knee joint support and the anti-collision piece: the knee joint support 211 is fixedly connected with the first anti-collision piece 22 and the second anti-collision piece 23, so that the anti-collision piece can accurately cover the key protection areas on both sides and the front of the knee joint; the first anti-collision piece 22 is symmetrically arranged to ensure that the forces on both sides of the knee joint and the front of the knee joint are balanced, and the second anti-collision piece 23 protects the rear part of the knee joint which is prone to collision, forming a dead angle-free protection.
[0038] The strength complementation of the weakening groove and the anti-collision piece: the first weakening groove and the second weakening groove improve the flexibility of the knee joint support 211, while the high-strength structure of the first anti-collision piece 22 and the second anti-collision piece 23 makes up for the strength loss at the first weakening groove and the second weakening groove, so that the device has a certain degree of activity while still maintaining reliable protection performance.
[0039] The stable connection of the plug-in part and the U-shaped connecting seat: the plug-in part 213 is plug-in connected with the U-shaped connecting seat 12, and the locking bolt 24 is in abutment and fixed, so that the stable connection of the knee joint fixing assembly 2 and the foot fixing assembly 1 is realized, and the two will not relatively displace when the patient walks or moves, ensuring the continuity and stability of the protection.

The screwing cooperation of the adjusting screw 343 and the universal ball head 342 enables the fitting force of the round flat hollow pressing piece 344 and the ankle joint to be finely adjusted by rotating the adjusting screw 343, and the operation is simple and the adjusting precision is high. The round flat hollow pressing piece 344 is made of medical silica gel, is soft and skin-friendly, matches the contour of the ankle joint, and avoids discomfort caused by local compression. The round flat hollow pressing piece 344 not only can press the medical cotton, but also can press and rub the ankle joint. The U-shaped elastic pieces 3452 are made of medical elastic material, have excellent elastic recovery force, can uniformly disperse external impact force, and can adapt to the deformation of the round flat hollow pressing piece 344 by deforming themselves, so as to provide continuous and stable buffer support for the ankle joint.

[0048] The buffering cooperation of the round flat hollow pressing piece and the elastic buffer: the fitting property of the round flat hollow pressing piece 344 and the circumferential array distribution of the U-shaped elastic piece 3452 make the pressing force uniformly transmitted to the surface of the ankle joint, so that local pressure concentration is avoided; at the same time, the elastic restoring force of the U-shaped elastic piece 3452 can buffer the external impact force in real time.
[0049] The overall fixing of the elastic connecting plate and the L-shaped connecting seat: the clamping cooperation of the elastic connecting plate 35 and the L-shaped connecting seat 13 realizes the stable connection of the ankle joint protection assembly 3 and the foot fixing assembly 1, so that the protection of the ankle joint forms an integral whole.
