Portable muscle mechanical parameter and muscular strength in vivo ultrasonic detection device and method

Abstract

The invention discloses a portable muscle mechanical parameter and muscular strength in vivo ultrasonic detection device and method. The device consists of a broadband ultrasonic probe, a multi-channel ultrasonic system and a man-machine interactive system, wherein the multi-channel ultrasonic system communicates with the man-machine interactive system through a local area network or a USB (universal serial bus) 3.0 interface. The device performs ultrasonic signal acquisition on the muscle of a human body or an animal in vivo, performs intelligent analysis and processing on a detection signal in time, extracts a plurality of characteristic parameters related to the muscle strength to perform imaging respectively, supports tracking and tracing measurement under a multi-image model, combines the traditional B scanning image to realize measurement and quantitative display of the mechanical property parameters and the muscle strength of single muscle, and predicts the health state of the muscle according to a muscle preset threshold value and gives alarm prompt correspondingly. According to the device and the method, in vivo, non-invasive, real-time, precise and overall quantitative evaluation on the muscle mechanical properties and the muscle strength is realized.

Description

technical field [0001] The invention relates to the field of biomechanics, in particular to a portable ultrasonic detection device and method for muscle mechanical parameters and muscle force in vivo. Background technique [0002] Muscle is the power source for organisms to complete various actions, and the dynamic characteristics of muscle force during exercise is one of the main contents of biomechanics research. The in-depth study on the quantitative evaluation of muscle force will help to expand the research scope of biomechanics and promote the development of bionic mechanical design, biomedicine, competitive sports and other disciplines. However, due to the redundancy of muscles, individual differences, diversity and in vivo experiments The limitation of this method makes it very difficult to carry out the research work on the quantitative evaluation of the muscle force of the organism, especially the quantification of the single muscle force is one of the problems tha...
