Evaluation device and evaluation method for muscle function state on the basis of photoelectric signal detection

Abstract

The invention discloses an evaluation device and an evaluation method for a muscle function state on the basis of photoelectric signal detection. The evaluation device comprises at least one photoelectric receiving diode, a plurality of LEDs (light emitting diode) with different wavelengths, a signal processor, an internal optical isolation barrier, an external shading barrier and a transparent isolation layer thin film, wherein the signal processor controls driving circuits for the LEDs and the photoelectric receiving diode and processes the receiving signal of the photoelectric receiving diode; the internal optical isolation barrier is positioned between the LEDs and the photoelectric receiving diode; the external shading barrier shades external light for the LEDs and the photoelectric receiving diode; and the transparent isolation layer thin film is arranged in a working direction of the LEDs and the photoelectric receiving diode and directly acts on a detected skin surface. The evaluation device can detect the mechanomyograph, the oxygen content of blood, the heart rate parameter and the like of muscle on a target position in real time so as to evaluate the muscle function state.

Description

technical field [0001] The invention belongs to the field of biomedicine, and in particular relates to an evaluation device and evaluation method of muscle function state based on photoelectric signal detection. Background technique [0002] Stroke, pelvic floor dysfunction and other external traumas such as fractures and surgery will cause varying degrees of damage to the relevant muscles of the human body. Evaluation of the functional state of the muscles can help patients treat and recover. The traditional evaluation method of muscle function status is realized through the subjective feeling of the patient or the subjective judgment of the doctor. Such a method lacks scientific basis and is prone to misdiagnosis due to personal subjective judgment errors. [0003] In addition, one of the more popular scientific evaluation methods of muscle function status is electromyographic signal (EMG) detection, that is, to judge the function status of muscles by detecting the action ...

Problems solved by technology

[0006] The article Method for measuring mechanical vibrations from isometrically contracted muscles mentions a method of measuring muscle signal (MMG) with a laser ranging sensor, but this method can only measure muscle signal (MMG), and cannot simultaneously measure muscle signal (MMG) , blood oxygen levels and heart rate, not to mention the measurement of muscle state

Of course, because the method in the article is unable to obtain the measurement of comprehensive physiological parameters of muscle function state measurement during exercise, including blood oxygen content and heart rate, it is impossible to give a more accurate measurement of muscle function state

[0007] The patent application with the application publication number CN107684433A discloses a device and method for simultaneously detecting multiple physiological parameter indicators of the wound surface, using photoelectric signal sensors to detect signals, but the device realizes the detection of wound physiological parameters by introducing various component sensitive films , and there is only a detection method, and no further analysis method
