Problems solved by technology

[0005] 2. Human-computer interaction is limited to the feedback of measurement information. In the process of training and learning, the positive reinforcement effect on the learning effect is not obvious;
[0006] 3. The therapist needs to adjust the target threshold in time according to the feedback information during the practice process, which cannot meet the home training needs of the treated person

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0024] The cardiovascular system is the main target cell of the stress response. When the stress load is too strong or the stress lasts too long, it will have adverse effects on the cardiovascular system. Usually, when people are in a state of stress or the stress load is strengthened, the physiological defense compensation caused by the sympathetic-adrenal medullary system will lead to changes in cardiovascular parameters, such as increased heart rate, increased cardiac contractility, increased peripheral total resistance and Blood redistribution, increased cardiac output, increased blood pressure, increased myocardial oxygen consumption, etc., such as figure 2 shown. Studies have confirmed that scientific and effective relaxation training can help relieve psychological stress and reduce anxiety levels, thereby better controlling and enhancing the n...

Abstract

The invention discloses a biological feedback system based on pulse waves. According to the technical scheme, based on the haemodynamics principles of the pulse waves, blood pressure and pulse wave signals of a human body are recorded through a collecting instrument, the feature information of the pulse waveform is analyzed to obtain physiological parameters related to the angiocarpy of the human body, a multimedia video interactive system is further used to carry out physiological signal feedback and strengthening, stepped training targets are set automatically, a user is guided to carry out biological feedback training and the relaxation training, training strengthening effect is improved by the soothing multimedia video-audio effect combined with visual visualization angiocarpy physiological signal feedback and by using small-step-progressive target setting, and accordingly the effectiveness of user autonomous relaxation training is improved. The biological feedback system is widely applicable to home treating of various physical and mental diseases and health care, training strengthening effect is improved, and the effectiveness of user autonomous relaxation training is improved.

Description

technical field [0001] The invention relates to a biomedical instrument, in particular to a pulse wave-based biofeedback system. Background technique [0002] The basic principle of biofeedback therapy is to amplify the signals of internal organ activities regulated by the human autonomic nervous system through certain detection instruments, and convert them into visual and auditory signals that can be perceived by the eyes and ears, so that people can perceive these internal organs. By consciously changing the mental state, the physiological changes can be adjusted to improve towards a certain goal. [0003] Commonly used biofeedback instruments mainly include: electromyographic feedback instrument, which can restore paralyzed muscle movement by feeding back muscle tension signals to achieve the purpose of rehabilitation; skin temperature feedback instrument, which can train patients to learn to regulate skin temperature, treat migraine, anxiety, etc.; Feedback instrument,...
