Description

Technical Field

[0001] The present invention relates to the technical field of psychological stress assessment, and in particular to a psychological stress assessment method and device combined with sleep conditions. Background Art

[0002] The pace of modern society is getting faster, and more and more people are beginning to pay attention to their own mental stress state. In the prior art, there are many stress monitoring schemes based on physiological signals, such as monitoring stress through heart rate variability. The human autonomic nervous system is divided into two branches, the sympathetic nerve and the parasympathetic nerve. The two interact with each other. When under tension and stress, the sympathetic nerve will play a leading role, and vice versa, the parasympathetic nerve will dominate. When the parasympathetic nerve is dominant or relatively active, it will not only reduce our heart rate, but also provide more space for changes between consecutive heartbeats. The regulation of the parasympathetic nerve is immediate, but one regulation can only affect a few heartbeats, and then the heart will return to its inherent frequency. In other words, it is relatively relaxed and stress-free, the parasympathetic nerve is dominant, and your body will beat only when it feels that the heart needs to beat. The beating rhythm is more random when meeting the needs of the body, so there will be large fluctuations between consecutive heartbeats. When you are nervous and stressed, when the sympathetic nerve branch controls the body, the heart beats with a clear rhythm. Heart rate variability can measure the rhythm of the heartbeat; heart rate variability = heart rate variance mean / (heart rate mode + heart rate mean). The smaller the heart rate variability value is, the greater the stress and the more tired the body is on that day; the larger the heart rate variability value is, the less stress and the better the body condition is. However, the test process itself brings a certain amount of stress to the patient, which will affect the physiological characteristics and lead to inaccurate results of the stress test.

[0068] Anxiety was scored based on the Generalized Anxiety Scale according to actual feelings in the past two weeks. The frequency of the scoring items in the Generalized Anxiety Scale is divided into 4 levels, including: not at all, a few days, more than half of the days, and almost every day; each frequency is scored from 0 to 3.

[0069] During the specific implementation process, the sleep problem situation is determined according to the sleep score on a percentage basis: when X≤25, there is no obvious sleep problem; when 25<X≤50, it is a mild sleep problem; when 50<X≤75, it is a moderate sleep problem; when X>75, it is a severe sleep problem, where X is the sleep score on a percentage basis; the depression situation is determined according to the depression score Y: a depression score Y below 52 is normal, 53-62 is mild depression, 63-72 is moderate depression, and 73 points and above is severe depression; the anxiety situation is determined according to the anxiety score J: when the anxiety score J is 0-4, there is no anxiety disorder; when it is 5-9, there may be mild anxiety disorder; when it is 10-13, there may be moderate anxiety disorder; when it is 14-18, there may be moderate to severe anxiety disorder; when it is 19-21, there may be severe anxiety disorder.

[0070] Collect multi-dimensional vital sign parameters of the person to be evaluated, including blood oxygen, blood pressure, heart rate parameters at rest, and brain waves at rest. And score the multi-dimensional vital sign parameters.

[0071] Respiratory diseases cause mental disorders mainly because respiratory disorders cause insufficient oxygen intake in the body, resulting in insufficient blood oxygen concentration, which affects the functions of various organs of the body, especially the nervous system, resulting in mental disorders, causing patients to be confused, weaken their control over themselves, and unable to correctly view and respond to external stimuli, and make overreactions or inappropriate reactions. The main clinical manifestations are anxiety, depression, cognitive dysfunction, and even stupor, delirium, and coma. Hypoxemia can cause cognitive dysfunction and impaired consciousness. Moderate hypercapnia can cause headaches, dizziness, indifference, and forgetfulness, while severe hypercapnia can lead to stupor or coma. This application uses a blood oxygen clamp to collect blood oxygen saturation data and evaluate it. If the blood oxygen saturation is <95%, the blood oxygen saturation score XY is 3, 95≤blood oxygen saturation≤100, and the blood oxygen saturation score XY is 0.

[0072] The incidence of sleep disorders in people with hypertension has increased significantly. The incidence of insomnia in patients with hypertension is 40%, and it shows an increasing trend as the course of the disease increases. Sleep can affect blood pressure by changing autonomic nervous function and other physiological factors. Insomnia can lead to increased blood pressure. In turn, increased blood pressure can also affect sleep through pathways such as neurohumoral regulation, aggravating insomnia symptoms. Hypertension and sleep problems in such patients are mutually influential and causal. Therefore, blood pressure is also an important factor in judging sleep quality. For example, problems such as excessive mental stress or anxiety may cause insomnia. Long-term lack of sleep or poor quality may lead to autonomic dysfunction, which in turn affects the heart's ability to pump blood and leads to hypotension. Too low blood pressure will affect sleep, because too low blood pressure will cause clinical symptoms of low perfusion, that is, insufficient blood perfusion in the capillaries, and obvious insufficiency of blood supply to the nervous system. Long-term autonomic dysfunction will cause sleep problems. Severe hypotension will cause serious autonomic dysfunction, and there will be obvious clinical symptoms and reactions such as insomnia and dreaminess. There is a certain correlation between blood pressure and psychology: young men with elevated resting heart rate and blood pressure, but still within normal range, are more likely to suffer from various mental illnesses, including obsessive-compulsive disorder, schizophrenia, and anxiety. People with high blood pressure are prone to tension, hostility, and prejudice. Long-term low blood pressure leads to mental illnesses such as fatigue, mental exhaustion, depression, and melancholy.

[0073] This application uses a blood pressure cuff to collect the patient's instantaneous blood pressure at rest, including systolic pressure and diastolic pressure. Scoring is performed based on the systolic and diastolic pressures, including:

[0074] When systolic blood pressure ≥140 mmHg and / or diastolic blood pressure ≥90 mmHg, blood pressure is too high and the blood pressure score Z is 3 points; when systolic blood pressure <90 mmHg and / or diastolic blood pressure <60 mmHg, blood pressure is too low and the blood pressure score Z is 3 points; 90 < systolic blood pressure <140 mmHg and / or 60 < systolic blood pressure

[0075] When the blood pressure is <90 mmHg, the blood pressure is normal and the blood pressure score Z is 0.

[0076] The relationship between heart rate and sleep: A general indicator of sleep quality is the average heart rate during sleep. The standard value of heart rate during sleep is about 50 beats / minute. The standard heart rate of an average adult should be 60-100 beats / minute. The heart rate during sleep is usually lower than 60 beats / minute. As long as it is not lower than 40 beats / minute, it is normal; if the patient's heart rate during sleep is lower than 40 beats / minute, it affects the quality of sleep. The relationship between arrhythmia and sleep varies with age and cause, that is, arrhythmia can affect the quality of sleep. Some patients with arrhythmia may have palpitations, discomfort in the precordial area, and some anxiety, which may cause sleep disorders, such as difficulty falling asleep, shallow sleep, dreaming, intermittent sleep, etc. Slow arrhythmias may also cause symptoms of reduced cardiac output, such as fatigue, shortness of breath and drowsiness. In addition, sleep itself and sleep disorders can also cause or aggravate arrhythmias.

[0077] This application uses a blood oxygen clamp to synchronously monitor the heart rate and monitor the patient's heart rate at rest. The heart rate is scored. When the heart rate level is <60, the heart rate is low and the heart rate U score is 0 points; when the heart rate level is 60≤≤100, the heart rate is normal and the heart rate U score is 0 points; when X>100, the heart rate is too high and the heart rate U score is 4 points.

[0078] The EEG monitoring equipment is used to collect brain wave signals through the contact points of the back earlobe and forehead. Brain wave activities have certain regular characteristics and correspond to the consciousness of the brain to a certain extent. When people are in different states such as excitement, tension, and coma, the frequency of brain waves will be significantly different, ranging from about 1 to 40 Hz. According to different frequencies, brain waves are further divided into α, β, δ, θ, and γ waves. When people are highly cognitive, the frequency of brain waves is higher than 30 Hz, and this band is called γ waves. When people are under certain pressure and highly concentrated, the frequency of brain waves is between 12 and 30 Hz. This band is called β waves, which are brain waves at the "conscious" level; when people's attention decreases and they are in a relaxed state, the frequency of brain waves will drop to 8 to 12 Hz, which is called α waves; after entering the sleep state, the frequency of brain waves drops further and is divided into 4 to 8 Hz θ waves and 0.5 to 4 Hz δ waves, which respectively reflect the state of people in the "subconscious" and "unconscious" stages.

[0079] This application uses the four waveforms that are most closely related to the psychological sleep state: alpha wave, beta wave, delta wave, and theta wave.

[0080] The eSense algorithm converts alpha waves, beta waves, delta waves, and theta waves into eSense index values ​​of relaxation and concentration. The eSense index value of concentration is used as the attention score; the difference between the eSense index values ​​of relaxation and concentration is used as the difference score of concentration attention.

[0081] eSense is an algorithm used to measure a person's current mental state in a digital index. The eSense index indicates the user's concentration and relaxation levels with a specific value between 1 and 100. The eSense index of 1-100 is graded in three stages:

[0082]

[0083]

[0084] The depression and anxiety states are determined according to the relaxation degree F, concentration degree Z and the difference between relaxation degree F and concentration degree Z, including: when relaxation degree F≤50 and concentration degree Z≤50, the state is normal; when relaxation degree F≥50 and concentration degree Z≥50, the state is normal; when relaxation degree F<50 and concentration degree Z>50, if |FZ|≤20, the state is normal, if 20<|FZ|≤45, it is mild anxiety, if 45<|FZ|≤70, it is moderate anxiety, if |FZ|>70, it is severe anxiety; when relaxation degree F>50 and concentration degree Z<50, if |FZ|≤20, the state is normal, if 20<|FZ|≤45, it is mild depression, if 45<|FZ|≤70, it is moderate depression, if |FZ|>70, it is severe depression. As shown in the following table:

[0085]

[0086]

[0087] The state table corresponds to the following:

[0088] Focus Low Low middle high high Relaxation Difference [1，20] (20，40] (40，60] (60，80] (80，100] Low [1，20] Good condition Normal status Mild anxiety Moderate anxiety Severe anxiety Low (20，40] Normal status Good condition Normal status Mild anxiety Moderate anxiety middle (40，60] Mild depression Normal status Good condition Normal status Mild anxiety high (60，80] Moderate depression Mild depression Normal status Good condition Normal status high (80，100] Severe depression Moderate depression Mild depression Normal status Good condition

[0089] The sleep score, depression score, and anxiety score are steady-state scores. In this application, the sleep score, depression score, and anxiety score are used as conditional scores.

Thus, the final stress state is obtained based on the dynamic and steady-state scores.

[0092] The pressure assessment network code using LSMT as an example is as follows:

[0093]

[0094]

[0095] The training data used for training the stress assessment network include conditional scores, time series scores and stress level labels. The cross entropy loss between the predicted stress level and the actual stress level label is used as the loss function. The goal is to minimize the loss function. The stress assessment network is trained through the gradient descent algorithm, and the training uses the Adam optimizer.
