Description

Wearable Achilles tendon information collection and monitoring system

technical field

The invention relates to a method of collecting human Achilles tendon data information by using a wearable sensor, and transmitting the collected data to an open cloud processing center for data analysis and feature extraction through a smart device, and then sending the analysis result back to the smart device for the user Browse wearable human Achilles tendon information collection and monitoring system.

Background technique

The main function of the Achilles tendon is to be responsible for the plantar flexion of the ankle joint, which plays an important role in the completion of walking, running, jumping and other movements. Achilles tendon rupture is often a common sports injury, and its incidence has been increasing in recent years. After Achilles tendon rupture, the walking function of patients will be seriously affected.

Numerous studies at home and abroad have shown that after wearing high-heeled shoes, the load-bearing line of the human body changes, the heel is raised, and the pressure on the foot is redistributed. Long-term wearing of high-heeled shoes may lead to changes in the structure and function of the human calf muscle-tendon tissue, which will eventually change the mechanical properties of the lower limbs and cause some physiological diseases. Relevant reports have proved that wearing high heels for a long time will lead to structural and functional changes in the calf muscles, such as the increase in the strength of the Achilles tendon and the reduction in the strength of the ankle joint, by using technologies such as nuclear magnetic resonance imaging technology, ultrasonic imaging technology, and isokinetic muscle strength tester. range of activities. Relevant foreign research groups explored the changes in the neuromechanical characteristics of humans during walking by studying the plantar pressure and the changes in the kinematic characteristics of the ankle and knee joints, observing the activity of the Achilles tendon, and measuring the length of the fibers of the Achilles tendon. Long-term wearing of high heels increases the risk of Achilles tendon injury, leading to muscle discomfort and fatigue.

Plantar pressure distribution characteristics are one of the important indicators that affect the health of the Achilles tendon. The measurement of plantar pressure distribution has important guiding significance in the fields of rehabilitation medicine, orthopedic surgery, sports training, and shoemaking. The pressure test board and test bench technology currently used in clinical practice has great space limitations and is not wearable. Therefore, the development of an Achilles tendon information collection and monitoring system with a wearable plantar pressure device has become an important work in this technical field.

The ankle joint and the metatarsophalangeal joint are important joints for lower limb activities, and play an important role in the force magnitude and direction of the Achilles tendon. Therefore, in these sports, the ankle joint and metatarsophalangeal joint have a normal range of motion. In the current sports training, whether the athletes' movements are reasonable or not is usually observed by naked eyes and video playback. These two methods can only rely on people's subjective judgment and cannot provide objective judgment basis.

During the past medical research and development, researchers invented and used many human body characteristic sensors. However, these devices are all designed to be used in the environment of a hospital consulting room, and the equipment is bulky and heavy, and professionals are required to operate and use them. Data processing and analysis also need to be done manually by professionals. In recent years, researchers have begun to use microprocessors and data acquisition systems to collect and digitize human body characteristic information, and transmit the data remotely through the network for analysis and diagnosis by professionals.

Based on previous work, the existing technology mainly has the following defects: many sensors, such as electrocardiographs, need to place multiple probes on different parts of the human body. Some machines, such as ultrasound imaging machines, require conductive fluid to be applied to the body. These instruments are suitable for use in a clinic environment and are operated by medical professionals. But for the daily use of ordinary users, these devices become very inconvenient or even unusable. Another challenge is how to place these sensors on the human body for a long time without causing discomfort to the user. The ideal design is to allow ordinary users to carry out normal work and engage in various activities after wearing it. In addition, the sensors and their supporting data acquisition and transmission systems for ordinary users should not only be cheap, but also allow ordinary users to replace them every one to two years. In addition, on the remote server side, the previous invention only uses it to store data. Data analysis is mainly analyzed and interpreted manually by professionals. This approach is only suitable for specialized medical institutions serving a limited number of patients. But when there are tens of thousands, even millions of users uploading their Achilles tendon data to the server regularly, it is obviously unrealistic to rely on manual analysis. The entire data collection, uploading, analysis and reporting of results must be automated. Although there are data analysis automation and expert systems, these systems are closed structures. That is, only the system designer can change or add new analysis methods. But the wisdom and capabilities of a company or research institution are limited after all. The ideal approach is to open the data analysis platform to experienced and qualified experts and scholars around the world. They are encouraged to take full advantage of this data to develop better analysis and forecasting methods.

Nowadays, data mining technology is widely used in clinical medicine. It has become a reality to analyze and mine the daily physical activity data of each person, and to provide health advice or disease warning.

On the other hand, industrial progress has made various semiconductor chips and sensors smaller and smaller, more power-saving, more powerful, and cheaper, so that more and more ordinary consumers can Widely used in daily life. At the same time, with the popularity of instant messaging and social media, more and more people use cloud centers to store and exchange information and data.
