Description

Technical Field

[0001] This utility model relates to the field of human sports protection technology, specifically to an airbag-cushioned knee joint protection and rehabilitation training medical aid. Background Technology

[0002] The knee joint is a crucial hub for weight-bearing and movement, and an essential functional foundation for daily life activities such as standing and walking. Anterior cruciate ligament (ACL) injury is one of the most common knee ligament injuries in orthopedics, particularly prevalent in high-intensity sports such as basketball, soccer, volleyball, handball, hockey, gymnastics, and alpine skiing. The age of onset is increasingly younger, and the injury often occurs alongside chronic accumulation of sports-related injuries. Furthermore, ACL injuries require a long recovery period after surgery, typically one to two years, to fully restore normal activity levels. The recurrence rate is also high, and patients are more likely to experience decreased exercise tolerance.

[0003] Most existing knee brace products on the market are of general-purpose design with relatively simple structure. They lack sufficient protection, support and shock absorption, and the support is not even. They are also not comfortable, breathable, and have an overly complex structure. They cannot effectively cope with the impact and rotational instability that the knee joint may suffer during exercise after ACL surgery, and cannot meet the dual needs of professional rehabilitation and sports protection.

[0004] Traditional ACL knee braces can only absorb impact through the physical deformation of materials such as silicone pads, sponges, and elastic fabrics. Their specific cushioning effect is limited, their support performance is insufficient, and their response to fall impacts is not rapid enough. They also only provide basic fixation and pressure distribution, unable to dynamically respond to sudden impacts. Functionally, traditional knee braces are mainly used for joint stability during exercise or for basic fixation after surgery, and cannot actively reduce high-energy impacts. The internal filling of traditional knee braces is uniformly distributed, failing to provide precise reinforcement to key stress points of the knee joint, such as the patella. Furthermore, the support strength of traditional knee braces is fixed and cannot be dynamically adjusted according to different activity needs. Utility Model Content

[0005] Purpose of the utility model: To address the above-mentioned shortcomings, this utility model provides an airbag-type knee joint protection and rehabilitation training medical aid that can precisely reinforce and quickly buffer direct impacts. It effectively cushions the direct impact on the knee joint in case of abnormal situations during exercise.

[0006] Technical solution: To solve the above problems, this utility model adopts an airbag-cushioned knee joint protection and rehabilitation training medical aid, including a first knee brace and a second knee brace for providing basic support, and an airbag cushioning module. The first knee brace, the airbag cushioning module and the second knee brace are sequentially hinged at the same point. The inner surface of the airbag cushioning module is provided with a micro-compression airbag, which expands when impacted.

[0007] Furthermore, the airbag buffer module is equipped with a hidden vent or air guide groove structure in the airbag storage area of ​​the miniature compressed airbag to ensure airflow circulation.

[0008] Furthermore, the micro-compressible airbag is encapsulated with a compressible material or aerogel, thereby achieving the requirement that the airbag is thin and inflatable.

[0009] Furthermore, both the first and second knee braces are provided with a wraparound elastic band for covering the human leg, and the wraparound elastic band is provided with Velcro for fixing.

[0010] Furthermore, both the first knee brace and the second knee brace are made of 3D three-dimensional fabric mesh.

[0011] Furthermore, both the first and second knee braces have several protruding anti-slip ribs on their inner surfaces. These ribs prevent the knee braces from sliding downwards.

[0012] Furthermore, the first knee brace, the airbag cushioning module, and the second knee brace are all equipped with modular support structures. These modular support structures are rigid or semi-rigid support plates. One end of the support plate is fixedly connected to the first knee brace, the airbag cushioning module, or the second knee brace, while the other end has a round hole. The round hole of the support plate connecting the first knee brace, the airbag cushioning module, and the second knee brace is fitted onto the same rotating shaft and rotates relative to the shaft. The modular support structures are symmetrically arranged on both the left and right sides.

[0013] Beneficial Effects: Compared to existing technologies, this invention has the advantage of incorporating a miniature compressed airbag within the airbag cushioning module. When worn, this miniature compressed airbag responds quickly to impacts during falls, cushioning the direct impact on the knee joint. Furthermore, the miniature compressed airbag is positioned on the outer side of the knee joint, directly in front of the patella, preventing subsequent restriction of movement. The airbag cushioning module can be removed for daily use and installed before exercise, adapting to different environments. The knee brace's tightness can be adjusted using a wraparound elastic band and self-adhesive Velcro, ensuring that postoperative pressure, external temperature, and humidity are within a suitable range to guarantee knee health and facilitate postoperative recovery.

[0018] like Figures 1 to 4 As shown, this embodiment presents an airbag-cushioned knee joint protection and rehabilitation training medical aid, which combines medical assistance and sports protection functions and is foldable. It includes a first knee brace 1 that provides basic support and conforms to the knee contour, fitting against the thigh; a second knee brace 2 that provides basic support and conforms to the knee contour, fitting against the lower leg; and an airbag cushioning module located directly in front of the patella, integrating a micro-compressed airbag and conforming to the knee contour. The micro-compressed airbag is located inside the airbag cushioning module, within the padding in front of the patella. When the airbag inflates, the flexible mesh padding expands elastically, providing cushioning space. Two wraparound elastic bands are provided on the side of the first knee brace 1 that fits against the thigh to secure it. Two wraparound elastic bands are provided on the side of the second knee brace 2 that fits against the lower leg to secure it. Four wraparound self-adhesive Velcro straps are provided on the outside of the four elastic bands for further fixation.

[0019] like Figure 3 As shown, a modular support structure 4 for connection is provided between the first knee brace 1 and the second knee brace 2, symmetrically connected on both sides. The first knee brace 1 and the second knee brace 2 are linked by detachable modular support plates, which may allow limited relative displacement to accommodate knee flexion. The main body of the modular support structure 4 is located on both sides of the knee brace, providing core support. It is a rigid or semi-rigid support plate. The first knee brace, the second knee brace, and the airbag cushioning module are all connected to the support plate. One end of the support plate is fixedly connected to the first knee brace, the second knee brace, or the airbag cushioning module, and the other end has a circular through hole. The circular through holes of the support plates connected to the first knee brace, the second knee brace, and the airbag cushioning module are all fitted onto the same rotating shaft and can rotate relative to this rotating shaft. The support plate is connected and fixed to the rotating shaft by a knob. When the knob is loosened, the support plate can rotate or be removed around the rotating shaft; after the support plate is installed in place, the knob is tightened to lock and fix the support plate. The modular support structure connects the airbag buffer module 3, the second knee brace 2, and the first knee brace 1 sequentially from the knee contact side outwards.

[0020] The inner surfaces of the first knee brace 1 and the second knee brace 2 are provided with several protruding anti-slip ribs. The anti-slip ribs in the first knee brace 1 and the second knee brace 2 prevent the knee brace from sliding downwards during exercise, thus ensuring the protection of the knee joint.

[0021] The airbag in airbag cushioning module 3 is a miniature compression airbag, which encapsulates compressible materials or aerogels, such as silicon aerogel or graphene composite aerogel. The compressible material or aerogel is pre-compressed and encapsulated before being installed inside the miniature compression airbag. When subjected to external force, the compressed material deforms, absorbing impact energy and achieving a rapid response without the need for an additional inflation mechanism. This allows the airbag to be thin, lightweight, and inflatable, undergoing elastic deformation upon impact. The airbag storage area features hidden vents or air channels to ensure airflow circulation, maintain pressure balance inside and outside the material, and prevent material deformation due to temperature changes or long-term compression. It also assists in impact response; the vents allow internal airflow during impact, aiding in uniform material deformation and improving cushioning efficiency. Furthermore, it provides moisture protection and heat dissipation by maintaining airflow inside and outside the airbag, preventing sweat buildup. Combined with the 3D mesh design of the knee brace, it helps regulate temperature and humidity.

[0022] In this embodiment, both the first and second knee braces are made of 3D three-dimensional fabric mesh. The tightness of the knee brace against the knee joint can be adjusted by the self-adhesive Velcro 5 and elastic strap 6, so that the pressure, external temperature and humidity of the knee joint after surgery are within a suitable range, so as to ensure the health of the knee joint and facilitate postoperative rehabilitation.
