Description

Technical Field

[0001] The utility model relates to the field of lower limb training equipment, in particular to a weight-bearing ankle joint fixing brace. Background Art

[0002] After ankle fractures heal and the cast or brace is removed, patients should be instructed in functional exercises, such as weight-bearing walking exercises. Weight-bearing exercises during the recovery period should be gradual, with the weight gradually increasing. This is because newly healed bones are much less robust than uninjured bones. Many patients struggle to control the weight they bear, leading to reinjury of the newly healed fracture site due to the inability to withstand the heavy weight. This causes unnecessary damage to both the patient's physical and mental well-being, as well as to medical resources.

[0003] To elaborate, when guiding traditional functional exercises, medical staff will ask patients to focus on comprehensive exercises, that is, weight-bearing walking exercises accompanied by muscle and joint functional exercises. When starting weight-bearing walking exercises, it is generally started with 10% of the weight of the affected limb, and gradually increased every 5 days until normal weight bearing. When the exercise is just started, the affected limb often has repeated swelling and pain symptoms. In order to ensure the stability of the joint, nursing staff often use wearable ankle fixation braces to assist patients in exercise. However, the previous braces only used traditional scales to measure the percentage of the patient's weight when measuring weight, and then judged whether the weight requirement was met based on the pressure felt by the limb. This results in large errors, and even dangerous hidden dangers such as insufficient or overweight weight bearing, and cannot guarantee the effectiveness of functional exercise.

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described below with reference to the accompanying drawings, in which:

[0020] Figure 1 A schematic diagram of a weight-bearing ankle fixation brace provided in an embodiment of the present invention. DETAILED DESCRIPTION

[0021] The following describes in detail embodiments of the present invention. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0022] The present invention provides an embodiment of a weight-bearing ankle joint fixation brace, specifically, Figure 1As shown, it includes: a leg support plate 100 and a foot support plate 200 that are interconnected. The leg support plate 100 is provided with a calf strap 101 and an ankle strap 102. Since this device is mainly used for patients with ankle fractures, it is particularly important to emphasize that the ankle strap 102 is thicker and wider than the calf strap 101. The foot support plate 200 is provided with a first adjustable upper 201 near the toes and a second adjustable upper 202 corresponding to the instep. In addition, a first pressure sensor 1 and a second pressure sensor 2 are provided on the bottom surface of the foot support plate 200. It can be understood that the first pressure sensor 1 is located at the front of the foot support plate 200, corresponding to the forefoot position; the second pressure sensor 2 is located at the back of the foot support plate 200, corresponding to the heel. The pressure sensors are provided at these two locations because the foot is the main force point when used as a support, so that more accurate and reliable stress values can be obtained. Continuing from the above, an indicator module 3 is provided on the first adjustable upper 201 and / or the second adjustable upper 202. The indicator module 3 is electrically connected to the first pressure sensor 1 and / or the second pressure sensor 2 for outputting stress information. In actual operation, the type of the indicator module 3 can be configured according to actual needs. For example, it can be a display device that outputs digital symbols or light signals in a visual manner to allow the user to understand the current load-bearing and stress-bearing conditions. In this example, for easy observation, the indicator module 3 needs to be provided on the first adjustable upper 201. It can also be expanded here that when a display screen is used as the indicator module 3, a curved screen or a flexible screen is preferably used, so that it can adapt to the structure of the first adjustable upper 201. For example, it can also be a sound broadcasting device that is convenient for users with poor vision to output the current load-bearing conditions in an audio manner. In this example, it is not limited to being provided on the first or second adjustable upper. Of course, a device that combines audio and video can also be used.

[0023] On the basis of the above embodiment, it can be expanded to say that the aforementioned first pressure sensor 1 and the second pressure sensor 2 are respectively embedded in the anti-slip silicone pad 203 formed on the bottom surface of the foot support plate 200 (the silicone pad is shown protruding in the figure, but in actual implementation, it can be considered to be embedded in the bottom of the support plate, and a hard pedal that abuts the pressure sensor can be provided at the silicone pad to facilitate accurate stress sensing), and the anti-slip silicone pad 203 can be separated, that is, corresponding to the sole and heel respectively. Based on this concept, it can also be pointed out that a telescopic mechanism 4 connected between the sole position and the heel position is provided at the foot support plate 200 for adapting to the foot length of different users. The telescopic mechanism 4 itself is a mature and common mechanical structure, and this utility model will not be described in detail. It can be further explained that for the first and second adjustable uppers mentioned above, the shoe ears 5 and the connecting buckles 6 can be used to adapt to the foot widths of different users. The connecting buckles 6 here can be of various forms. For ease of operation, nylon buckles are preferably used.

[0024] Since the application scenario of the present invention is aimed at a specific user group, in some better embodiments, a cushioning pad 7 is provided at the ankle strap 102 and / or at the leg support plate 100 corresponding to the position of the ankle strap 102 to improve the wearing comfort and compliance of the user, and further improve the safety of using the fixation brace; the material and structure of the cushioning pad can be designed as needed based on the goal of cushioning performance and making wearing more comfortable. For example, in some solutions, an inflatable and deflable airbag can be used, thereby adjusting the size of the cushioning pad 7 according to the user's personalized needs.

[0025] Finally, it can be supplemented that, first, it is possible to consider using wireless transmission of stress signals between the pressure sensor and the indication module, which can reduce the constraints of the connecting cables, while improving the user's freedom of movement and reducing the adjustment flexibility of the fixation brace; second, on this basis, the indication module 3 and the adjustable shoe upper adopt a detachable connection structure. Those skilled in the art can understand that the sensor transmits the sensing results to the indication module in a wired or wireless manner, which is a mature electrical technology. It can transmit signals directly or through the user's mobile terminal, background service terminal, etc. This is not the focus of the present invention and will not be limited or elaborated on.

[0026] In summary, by setting up pressure detection devices on the soles and heels respectively, the precision and accuracy of lower limb weight-bearing stress detection can be improved, and the weight-bearing situation can be timely output to the patient with the help of the indicator module located on the instep, so that the patient can timely grasp and adjust the stepping stress of the affected limb on the weight-bearing device. Specifically, after the patient wears the weight-bearing ankle fixation brace, he first uses the ankle strap to stabilize the ankle and uses the two shoe uppers to restrain the foot. Then, by gradually touching the affected limb to the ground, the pressure sensors on the soles and heels sense and transmit the stress, and then the corresponding weight information is output through the indicator module. This feedback allows the patient to judge the weight-bearing situation based on the current weight-bearing indication, so as to effectively complete the walking training.
