Description

Technical Field

[0001] The present invention relates to the technical field of orthopedics, and in particular to an emergency treatment device for ankle sprains. Background Art

[0002] Ankle sprains are a very common sports injury in sports and daily activities, often caused by violent twisting, unstable landing, or external impact, leading to ligament strain, soft tissue tear, or even fracture. Medical research shows that emergency treatment after an ankle sprain (RICE principle) is particularly important, with ice and immobilization being key steps. They should be implemented immediately after the injury, reducing swelling and pain by constricting blood vessels through low temperatures. Traditional rigid protective gear (such as braces and casts) can limit joint movement and prevent secondary injury, but they have significant drawbacks. Once worn, the protective gear is difficult to directly contact the skin, and ice packs cannot effectively adhere to the affected area, resulting in poor cooling effect. In addition, traditional protective gear is bulky and rigid, making it impossible to wear it in regular shoes. The soles lack supportive design that adapts to the arch of the foot, forcing patients to hop on one foot or rely on crutches, seriously affecting their mobility.

[0003] Currently, most ankle braces on the market focus on a single function (such as providing only fixation or elastic compression), failing to integrate the synergistic needs of ice packs and rigid fixation. Some products have attempted to improve this by designing detachable ice packs, but the ice packs are easily displaced, the cooling source is unevenly distributed, and the rigid support structure still affects walking stability. Therefore, there is an urgent need for an integrated brace that combines instant ice packs, rigid fixation, and walking functionality to resolve the contradictions in the existing technology. Summary of the Invention

[0004] The purpose of the present invention is to provide an emergency treatment device for ankle sprains to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A device for emergency treatment of ankle sprains, comprising a contoured foot support: the contoured foot support comprises a sole support and a calf guard, the sole support and the calf guard are an integrated fixed structure, a forefoot tightening belt is provided at the front end of the sole support, a calf tightening belt is provided at the upper and lower parts of the calf guard, and a four-point ankle tightening device is provided at the connection position between the sole support and the calf guard; the four-point ankle tightening device comprises a pair of Y-shaped side straps respectively arranged on both sides of the ankle, the two fixing points of the Y-shaped side straps are respectively located at the bottom of the calf guard and the root of the sole support, the inner sides of the inner and outer Y-shaped side straps are detachably connected with pressurized ice bags, the inner pressurized ice bag is located on the outside of the deltoid ligament, and the outer pressurized ice bag is located on the outside of the anterior talofibular ligament, the calcaneofibular ligament, and the posterior talofibular ligament.

[0007] Furthermore, the pressurized ice pack includes an ice pack having an opening at the top, and a plurality of ice pack compartments separated by bag partitions in the ice pack, wherein stainless steel ice cubes or ice bags are placed in the ice pack compartments.

[0008] Furthermore, a flexible protective pad is provided on the surface of the pressurized ice compress bag that contacts the skin.

[0009] Furthermore, the thermal conductivity of the flexible protective pad is 0.1 to 0.5 W / (m·K).

[0011] Furthermore, the pressurized airbag is a flat structure, and connecting columns that control the distance between the inner and outer walls of the airbag are evenly distributed inside the pressurized airbag. A non-elastic woven mesh is provided between the inner and outer Y-shaped side straps and the bottom of the calf guard and the base of the foot support, and the pressurized airbag is located on the inner side of the non-elastic woven mesh.

[0012] Furthermore, the sole support is divided into a rear half and a front half, the rear half is made of a hard material, and the front half is made of a tough material.

[0016] 1. The present invention achieves a close fit between the ice bag and the skin through the integrated design of the contoured foot support, pressurized ice pack and four-point tightening device, thus solving the problem that traditional protective gear cannot provide ice. The sole support of the contoured foot support provides arch support, and the calf guard is hollowed out to reduce weight, so that the patient can walk in shoes. The pressurized airbag controls the direction of pressure through the connecting column, and combines with the non-elastic woven mesh to apply pressure evenly and reduce swelling. The ice pack and airbag can be disassembled separately to meet the needs of different injury stages. The present invention provides an integrated device with instant ice compress, rigid fixation and walking functionality, which effectively solves the defects of the prior art.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example 1: Please refer to Figures 1 to 9, an emergency treatment device for ankle sprain, including a contoured foot support: the contoured foot support includes a sole support 2 and a calf guard 1, the sole support 2 and the calf guard 1 are an integrated fixed structure, the front end of the sole support 2 is provided with a forefoot tightening belt 4, the upper and lower calf guards 1 are respectively provided with a calf tightening belt 3, and the connecting position of the sole support 2 and the calf guard 1 is provided with a four-point ankle tightening device; the four-point ankle tightening device includes a pair of Y-shaped side straps 5 arranged on both sides of the ankle, the two fixed points of the Y-shaped side straps 5 are respectively located at the bottom of the calf guard 1 and the root of the sole support 2, the inner sides of the inner and outer Y-shaped side straps 5 are detachably connected with a pressurized ice pack 6, the inner pressurized ice pack 6 is located on the outside of the deltoid ligament, and the outer pressurized ice pack 6 is located on the outside of the anterior talofibular ligament, the calcaneofibular ligament and the posterior talofibular ligament.

[0030] The pressurized ice pack 6 includes an ice pack 13 , the upper end of which is open. The ice pack 13 is divided into a plurality of ice pack compartments 17 by bag partitions 18 , and stainless steel ice cubes or ice bags are placed in the ice pack compartments 17 .

[0031] A flexible protective pad 14 is provided on the surface of the pressurized ice pack 6 that contacts the skin.

[0032] The thermal conductivity of the flexible pad 14 is 0.1 to 0.5 W / (m·K).

[0033] A pressurized air bag 15 is provided on the surface of the pressurized ice pack 6 that does not contact the skin, and an air valve 16 is provided on the pressurized air bag 15 .

[0034] The pressurized airbag 15 is a flat structure, and connecting columns 19 for controlling the distance between the inner and outer walls of the airbag are evenly distributed inside the pressurized airbag 15. A non-elastic woven mesh is provided between the inner and outer Y-shaped side straps 5 and the bottom of the calf guard plate 1 and the root of the sole support 2, and the pressurized airbag 15 is located on the inner side of the non-elastic woven mesh.

[0035] The calf guard 1 is provided with a large hollow groove 12 .

[0036] Working principle of this embodiment:

[0037] like Figure 1 、 Figure 2 、 Figure 5 As shown, the integrated calf guard 1 and sole support 2 are constructed of rigid materials to form a contoured structure that conforms to the physiological curve of the calf to the sole of the foot. The large, hollowed-out grooves 12 on the calf guard 1 reduce weight and enhance breathability, while the arch support design of the sole support 2 allows patients to walk with regular shoes, avoiding single-foot hopping. The forefoot and calf straps 4 and 3-point fixation distribute pressure and prevent localized discomfort.

[0038] like Figure 7 、 Figure 8 、 Figure 9As shown, the pressurized ice pack 6 connected to the inner side of the Y-shaped side strap 5 is separated into multiple ice pack compartments 17 by bag dividers 18, ensuring that the stainless steel ice cubes / ice packs are evenly distributed and cover key ankle ligaments such as the deltoid ligament and talofibular ligament. The flexible pad 14 has a thermal conductivity of 0.1 to 0.5 W / (m·K), which can balance cooling efficiency and skin comfort to prevent frostbite.

[0039] like Figure 7 and Figure 9 As shown, after the pressurized airbag 15 is inflated through the air valve 16, the flat structure and internal connecting column 19 limit the expansion direction, so that the pressure acts vertically on the affected area. The inelastic woven mesh further evenly transmits the pressure, cooperating with the ice compress to constrict the blood vessels.

[0040] like Figure 6 As shown, the dual-fixation design of the Y-shaped side strap 5 forms a mechanical closed loop at the base of the calf guard and the base of the foot support, limiting ankle inversion and inversion while allowing slight sagittal plane motion for easier walking. The removable pressurized ice pack 6 facilitates replacement of ice packs or standalone use, resolving the single-function issue of traditional protective gear.

[0041] This embodiment integrates a pressurized ice pack 6 with a four-point tightening device to achieve a close fit between the ice pack and the skin, solving the problem of traditional protective gear being unable to apply ice. The contoured foot support 2 provides arch support, and the calf guard 1 is hollowed out to reduce weight, allowing patients to walk in shoes. The pressurized airbag 15 controls the direction of pressure through the connecting column 19, and the non-elastic woven mesh is combined to evenly apply pressure and reduce swelling. The ice pack and airbag can be removed separately to meet the needs of different injury stages.

[0042] Example 2: Please refer to Figures 3-5 , an emergency treatment device for ankle sprains, which differs from Example 1 in that the sole support 2 is divided into a rear half 7 and a front half 10, the rear half 7 is made of a hard material, and the front half 10 is made of a tough material. The front end of the rear half 7 is provided with a connecting piece 8 extending forward, and the connecting piece 8 is integrally formed inside the front half 10.

[0043] A rear anti-slip pad 9 is provided at the bottom of the rear half palm 7 , and a front anti-slip pad 11 is provided at the bottom of the front half palm 10 .

[0044] Working principle of this embodiment:

[0045] like Figure 3 、 Figure 4 As shown, the rear half 7 is made of a hard material, such as carbon fiber or high-strength plastic, to provide stable heel and arch support, prevent abnormal ankle torsion, and meet the rigid fixation requirement. The front half 10 is made of a flexible material, allowing the toes to flex naturally, adapting to the propulsion phase of walking, improving gait fluidity, and solving the problem of traditional protective gear with rigid structures that affect walking.

[0046] like Figure 4 As shown, the connecting piece 8 at the front end of the back half palm 7 is integrally embedded in the front half palm 10 to form a hard-soft transition zone, which not only ensures the stability of the back half palm, but also prevents the front half palm 10 from excessive deformation due to the tough material.

[0047] like Figure 3 、 Figure 5 As shown, the rear anti-skid pad 9 fits the heel to reduce the risk of sliding when landing; the forefoot anti-skid pad 11 covers the metatarsal area to ensure grip during propulsion.

[0048] This embodiment takes into account both the fixing and walking functions through the segmented structural design, and the connecting piece 8 realizes a smooth mechanical transition; the anti-slip pad improves the friction of the ground, avoids slipping when walking after wearing the protective gear, and further optimizes the safety of movement.
