A wearable knee joint monitoring device and monitoring method based on gprs communication

Abstract

The present invention provides a wearable knee joint monitoring device and monitoring method based on GPRS communication. The monitoring device includes a pair of knee joint straps, and a pair of sensors are respectively arranged on the inside of the two knee joint straps, and the sensors are connected to the sensors through lead wires. Transmitter, sensor The transmitter is connected to the GPRS data acquisition module through the RS-485 serial port. The data acquisition module stores the collected pressure value on the server side by accessing the fixed domain name and port number; the monitoring method uses the principle of density clustering , using four resistance strain pressure sensors to collect the pressure value of the meniscus of the knee joint, coordinate the pressure data collected by each sensor, and then use the Euclidean metric as the measurement basis to support the density-based clustering method to analyze The deviation degree of the pressure at the meniscus, compare and judge the actual deviation value with the standard deviation value. The invention realizes the preventive monitoring of patients with potential knee joint diseases.

Description

technical field [0001] The invention belongs to the technical field of knee joint monitoring, and in particular relates to a knee joint parameter measurement and monitoring device and monitoring method based on GPRS communication. Background technique [0002] With the development of society, population aging is an inevitable trend, which brings great challenges to the country. Aging poses new challenges to the medical security system, and also puts forward new requirements for medical devices. Knee joint diseases such as "X" legs and "O" legs will seriously reduce the quality of life of the elderly, and traditional medical devices cannot meet the needs of the corresponding population. [0003] For example, the common method of measuring the force of the knee joint needs to be realized through the motion capture system and fixed force measuring platform equipped in the gait laboratory, which is not only expensive, but also has a small range of use, and lacks analysis and fe...

Knee joint diseases such as "X"-shaped legs and "O"-shaped legs will seriously reduce the quality of life of the elderly, and traditional medical devices cannot meet the needs of the corresponding population

[0003] For example, the common knee force measurement method needs to be realized through the motion capture system and fixed force measuring platform equipped in the gait laboratory, which is not only expensive, but also has a small range of use, and lacks analysis and feedback on knee force data , has no practical significance for the prevention, monitoring and daily rehabilitation of patients with knee joint diseases
