Physical and mental relaxation training aid and breathing guiding mode display processing method

Abstract

The invention discloses a physical and mental relaxation training aid and a breathing guiding mode display processing method. The aid comprises an acquisition device, a data processing device and a microprocessor, the acquisition device is used for acquiring corresponding pulse data from a photoelectric sensor after human body pulse signals are collected by the photoelectric sensor, the data processing device is connected with the acquisition device and used for processing the pulse data into pulse capacity waveform signals, the microprocessor is connected with the data processing device and is used for processing the pulse capacity waveform signals obtained by means of processing the pulse data by the data processing device, so that a normalized heart rate variability (HRV) curve is obtained, power spectrum distribution is obtained after the normalized heart rate variability (HRV) curve is in Fourier transform, relaxation statuses and respiratory rate of a user are obtained by means of analyzing power spectrum, breathing guiding animation is displayed according to the respiratory rate so as to assist in relaxation training of the user, and a training effect (training score) is assessed and displayed after the training is finished. In addition, the physical and mental relaxation training aid is simple in structure and convenient to carry.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a portable auxiliary device for physical and mental relaxation training and a breathing guidance model display processing method. Background technique [0002] The traditional theory holds that the resting heart acts like a metronome, emitting a constant, regular rhythm. However, it is not. The heart does not beat at a constant rhythm, and the heart rhythm is very irregular even in a quiet state, and the time difference between consecutive heartbeats is a variable value. This natural variation in heart rate from time to time is called heart rate variability (HRV). [0003] Normal heart rate variability is due to the synergy of the two branches of the autonomic nervous system (sympathetic and parasympathetic) -- the functions that control the many nervous systems within the body. The sympathetic nerve speeds up the heart rate, while the parasympathetic nerve slows it ...

AI Technical Summary

Problems solved by technology

[0009] 1) It is only used for breathing guidance and cannot display the current relaxation state in time;

[0010] 2) It can only guide the user to breathe according to the set frequency, without automatic adjustment function;

[0011] 3) There is no function to evaluate the training effect of the entire training process;

[0012] 4) Connected with PC, bulky and heavy, not convenient for family or personal use
