This invention relates to an active pneumatic adsorption intelligent anti-fall shoe, addressing problems such as high failure rate of traditional anti-slip shoes in wet conditions, high false alarm rate of intelligent shoes, lack of active intervention capability, ankle injury caused by adsorption, limited alarm contact options, inability to link and upgrade warnings, and high operating noise. The key features of this intelligent anti-fall shoe are: a shoe body, a sole structure, an intelligent monitoring and control system, a pneumatic adsorption execution system, and a circuit control system. The circuit control system includes a graded warning module, a remote alarm module, an ankle safety protection module, a power supply module, and a wireless communication module. The shoe body is equipped with a charging port and a power indicator light. The intelligent monitoring and control system includes a multimodal sensor unit, a processing chip unit, a posture slope calculation unit, a data storage unit, and a clock unit. The remote alarm module outputs a remote alarm signal and is linked to a mobile phone number. The pneumatic adsorption execution system only performs the pneumatic adsorption action when the secondary critical fall warning set by the graded warning module is activated.

This utility model discloses a carbon fiber ankle joint rehabilitation brace. The foot protector has a U-shaped curved surface to cover the heel and the inner and outer sides of the foot. An ankle joint cylindrical protrusion is located at the upper apex of the foot protector, directly opposite the ankle joint. An ankle joint cylindrical cover is located at the lower end of the leg protector, fitting around the outer periphery of the ankle joint cylindrical protrusion and rotating around it. A rotating pin is inserted at the center of the ankle joint cylindrical cover for rotatable connection with the ankle joint cylindrical protrusion. The foot protector, ankle joint cylindrical protrusion, ankle joint cylindrical cover, and leg protector are all made of carbon fiber. This carbon fiber ankle brace is lightweight, wearable, and convenient. It can be used with existing footwear, provides stable support and reduces imbalance, and can replace CAM walking boots for ankle injury recovery. It is suitable for most sports shoes.

The invention provides a method for anterior joint gap segmentation and thickness measurement of an ankle joint, and belongs to the technical field of image processing. According to the method, an anterior X-ray image of an ankle joint is collected, a standard data set is constructed, and the data set is used for training an image segmentation and key point detection network. The method comprises the following steps: firstly, carrying out standardization processing on an anterior X-ray image of an ankle joint, and training a segmentation and key point detection model by utilizing an annotation data set; and then, applying the trained segmentation model to a new X-ray image, and predicting by using the model to obtain an ankle gap segmentation result. And finally, applying the trained key point detection model to an ankle joint gap segmentation result, predicting by using the model to obtain a detection result of eight key points, and calculating the average thickness of the ankle joint gap based on the key point detection result by using a mathematical algorithm and an image processing technology. The method can provide an accurate diagnosis basis for clinicians, helps orthopedists to quickly evaluate the health condition of the ankle joint, remarkably improves the accuracy and efficiency of ankle joint gap measurement, and reduces manual operation time and errors. The method has wide application prospects in the fields of ankle joint injury assessment, treatment effect monitoring and the like.

This invention belongs to the technical field of sports protective equipment and intelligent rehabilitation wearable devices, specifically relating to an artificial intelligence ankle brace suitable for daily sports protection, postoperative rehabilitation of ankle injuries, fall prevention for middle-aged and elderly people, and real-time monitoring of ankle status in sports enthusiasts. It includes an elastic ankle brace body and a sensor array disposed in the inner layer of the elastic ankle brace body. The sensor array includes at least one tension sensor, at least one pressure sensor, at least one balance sensor, and at least one instability sensor. This invention achieves comprehensive, real-time, and accurate monitoring of tension, pressure, balance, and instability during ankle joint movement. It integrates functions such as automated signal acquisition and processing, adaptive threshold dynamic adjustment, intelligent recognition of multiple movement modes, real-time warning of exceeding limits, fall risk assessment, emergency call functionality, and synchronous upload and analysis of movement data, combining physical elastic protection with intelligent and accurate monitoring and early warning.

This invention relates to the field of rehabilitation assistive devices for foot and ankle injuries, and discloses a supportive walking device for foot and ankle injuries, including a protective plate and a base plate. Both the protective plate and the base plate have a U-shaped cross-section. The protective plate is vertical, even positioned directly above one end of the base plate. Connecting plates are fixedly connected to both sides of the bottom of the protective plate. Connecting plates are symmetrically fixedly connected to the side walls of both ends of the base plate. A mounting shaft is fixedly connected to the outer side wall of the connecting plate. The connecting plates are rotatably mounted on the mounting shaft. Support components are provided on the sides of the protective plate and the base plate, which support and limit the position of the protective plate and the base plate. This invention, by providing support and limiting components, facilitates the fixing of the position of the protective plate and the base plate, thus protecting the foot and ankle. Furthermore, it can remove the restrictions on the protective plate and the base plate, allowing for rehabilitation exercises of the foot and ankle, which is beneficial for rapid recovery.
