Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a pressure-adaptive ankle brace. Background Technology

[0002] This section provides only background information relevant to this disclosure and is not necessarily prior art.

[0003] Traditional elastic bandage ankle braces only provide static, constant restraint and cannot detect and respond in real time to potential risky movements that could lead to lateral ankle sprains (such as excessive inversion) during ankle joint movement. This passive fixation method restricts the natural range of motion of the joint, and long-term reliance may lead to compensatory atrophy of the ankle muscles due to reduced demand on active muscle exertion, thereby weakening the joint's inherent stability.

[0004] Lack of dynamic feedback and alarm mechanisms: Existing traditional ankle brace technologies generally lack dynamic biomechanical feedback capabilities. They cannot monitor real-time changes in angle, speed, or pressure during ankle joint movement, and therefore cannot provide immediate warning or intervention signals when the joint is about to be in or has already been in a dangerous position (such as excessive inversion angle). At the same time, they also lack the function of monitoring and alarming for abnormal pressure caused by improper wrapping or activity (such as too tight causing poor circulation or too loose losing its protective effect).

[0005] Motivation for improvement:

[0006] By combining a pressure sensing module, a closed-loop feedback mechanism of "abnormal pressure on the lateral side of the foot → vibration warning" is realized, which reduces manufacturing costs while ensuring biomechanical function. Summary of the Invention

[0007] To address the shortcomings of existing technologies, this invention proposes a pressure-adaptive ankle brace suitable for providing rehabilitation support for lateral ankle sprains, which are common in patients with chronic ankle instability.

[0008] An adaptive pressure ankle brace includes a first fastening part, an ankle protection part, and a second fastening part connected in sequence. The first fastening part is a horizontally elongated strip structure that wraps around and fixes the upper part of the ankle. The second fastening part includes a first sub-strap and a second sub-strap, which pass through the sole of the foot and are respectively bonded to the first fastening part to secure the ankle. The first and second fastening parts are respectively provided with adhesive components. The inner layer of the ankle protection part is provided with a pressure sensor, and the pressure sensing module includes a pressure sensor and a motor.

[0009] Furthermore, the surface of the first fastening part closest to the human body is provided with a first adhesive component female surface, and the surface of the first fastening part away from the human body is provided with a first adhesive component female surface and a second adhesive component female surface; the surfaces of the first and second sub-bands closest to the human body are provided with a second adhesive component female surface; the first adhesive component female surface and the first adhesive component female surface are mated and connected; the second adhesive component female surface and the second adhesive component female surface are mated and connected. The aforementioned adhesive component can be Velcro. The stability of the device is enhanced through double adhesion.

[0010] Furthermore, the ankle brace has an elastic fiber layer on the side away from the skin, enhancing its overall elasticity and support.

[0011] Furthermore, the ankle protection part is provided with a hollowed-out part, which occupies 20%-30% of the area of ​​the ankle protection part.

[0012] Furthermore, the hollowed-out portion is designed to cut out the ankle bone area to avoid compressing the bony prominence.

[0013] Furthermore, the ankle support has a storage pocket on the side closest to the body, and the storage pocket is made of elastic material. The ankle brace can be stuffed into the storage pocket for easy storage and increased portability.

[0014] Furthermore, the first fastening part, the ankle protection part, and the second fastening part are made of the same material.

[0015] Preferably, the material is elastic knitted cotton with a thickness of 1.5mm and high breathability.

[0016] Preferably, the first fastening part, the ankle protection part, and the second fastening part are integrally formed or sewn together.

[0017] Furthermore, the pressure sensing module is powered by a button battery.

[0018] Beneficial effects:

[0019] Active dynamic protection and real-time early warning: Changing the traditional passive binding mode of ankle braces, it achieves real-time pressure sensing and pressure response. When the pressure on the lateral ankle joint exceeds the danger threshold, the system can automatically trigger a vibration warning, immediately alerting the user before or during a sprain.

[0020] Personalized Adaptive Fit: The ankle brace features an elastic material and an adaptive design to the arch shape of the foot, solving the problems of poor fit, easy shifting, or uneven pressure associated with traditional fixed-size ankle braces. It can more intelligently conform to the arch curve of different users, providing stable protection while significantly improving wearing comfort and versatility.

[0021] Rapid and precise biomechanical correction: After detecting a dangerous eversion movement, this invention has an extremely short correction response time, ensuring that the protective intervention occurs within the critical time window of the sprain. This achieves rapid and precise dynamic stability control, with effects far exceeding the static eversion angle limitations provided by traditional ankle braces. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, and the advantages of the present invention in the above and / or other aspects will become clearer.

[0027] like Figure 1-3 As shown, a pressure-adaptive ankle brace includes a first fastening part 1, an ankle protection part 2, and a second fastening part 3 connected in sequence. The first fastening part 1 is a horizontally elongated strip structure that wraps around and fixes the upper part of the ankle. The second fastening part 3 includes a first sub-strap 301 and a second sub-strap 302. The first sub-strap 301 and the second sub-strap 302 pass through the sole of the foot and are respectively bonded to the first fastening part 1 to fasten the ankle. The first fastening part 1 and the second fastening part 3 are respectively provided with adhesive components. The inner layer of the ankle protection part 2 is provided with a pressure sensing module 4, which includes a pressure sensor and a motor.

[0028] The first fastening part 1 has a first adhesive component female surface 701 on the side surface near the human body, and a first adhesive component female surface 702 and a second adhesive component female surface 703 on the side surface away from the human body; the first sub-band 301 and the second sub-band 302 have a second adhesive component female surface 704 on the side surface near the human body; the first adhesive component female surface 701 and the first adhesive component female surface 702 are connected in a mating manner; the second adhesive component female surface 703 and the second adhesive component female surface 704 are connected in a mating manner.

[0029] The ankle brace has an elastic fiber layer 6 on the side away from the skin.

[0030] The ankle protection part 2 is provided with a hollow part 5, which occupies 20%-30% of the area of ​​the ankle protection part 2.

[0031] The hollowed-out section 5 is hollowed out from the ankle bone of the human body.

[0032] The ankle protection part 2 has a storage bag 8 on the side closest to the human body, and the storage bag 8 is made of elastic material.

[0033] The first fastening part 1, the ankle protection part 2, and the second fastening part 3 are made of the same material.

[0034] The material used is elastic knitted cotton.

[0035] The first fastening part 1, the ankle protection part 2, and the second fastening part 3 are integrally formed or sewn together.

[0036] The pressure sensing module 4 is powered by a button battery.

[0037] The steps for using the device are as follows:

[0038] Step 1, Preliminary Preparation: Unfold the ankle brace and ensure the pressure sensor module is aligned with the easily sprained area on the outside of the ankle. Align the perforated part of the ankle brace with the bony prominence to avoid pressure.

[0039] Step 2: Secure the first fastening part by horizontally wrapping it around the area above the ankle. Adhere the female surface and the female surface of the first adhesive component to complete the first layer of fixation.

[0040] Step 3: Secure the second fastening part. Pull the first sub-band of the second fastening part taut from the inside of the foot outwards and upwards. Adhere the second adhesive surface of the first sub-band to the second adhesive surface of the first fastening part. Pull the second sub-band taut from the outside of the foot inwards and upwards, overlapping the first sub-band. Adhere the second adhesive surface of the second sub-band to the second adhesive surface of the first fastening part. This can be adjacent to or partially cover the adhesive points of the first sub-band, completing the second layer of reinforcement and locking.

[0041] Step 4: Inspection and Functional Test. Check the overall fit to ensure there is no excessive looseness or tightness, and that the elastic band at the arch adapts to the fit. Gently press the pressure sensor area of ​​the ankle support or perform a simulated inversion movement to test the pressure warning function and confirm that the battery has power and is functioning properly.
