Description

Stress Relief System to Improve Sleep Quality}

The present invention relates to a stress relief system. Specifically, it monitors the user's lifestyle and electrocardiogram signals, collects resting electrocardiogram waveforms, and plays a sound source to which resting electrocardiogram waveforms are applied when sleeping to relieve stress and provide stable sleep. It is about a stress relief system to improve sleep quality.

Recently, the number of people complaining of sleep disorders is increasing due to reasons such as intensifying competition due to industrialization, lack of sleep due to excessive work or diversification of working hours, changes in sleep patterns, and increased stress, and the quality of sleep is increasing along with interest in health. Efforts to improve are also increasing.

Sleep disorder is a broad concept that includes not getting healthy sleep, not being able to stay awake during the day despite getting enough sleep, or having difficulty sleeping or staying awake due to a disturbed sleep rhythm. It manifests itself in a variety of symptoms. there is.

In relation to this, the British daily newspaper Daily Mail cited a study published by the University of Warwick Medical School in the European Heart Journal and reported that long-term sleep deprivation increases the risk of stroke and heart disease, and according to Professor Cappellichio, who led the study, 6 per day. Research has shown that if you do not sleep for more than an hour, you have a 48% higher risk of dying from or suffering from heart disease, and a 15% higher risk of dying or having a stroke, raising awareness of the importance of sleep. there is.

Traditionally, the use of drugs such as sleeping pills has been used to solve these sleep disorders, but not only is expert diagnosis, prescription, and dispensing essential, but there is also a risk of increasing drug dependence and leading to chronic insomnia, and taking the drug itself is harmful to patients. It is avoided because it can cause stress to people.

Accordingly, methods of using natural foods that induce sound sleep without negative effects or side effects on the human body, sound sources such as white noise, natural sounds, and classical music that induce psychological stability, or sound sources that induce stability of brain waves have emerged. However, it is not uncommon for there to be no effect at all depending on the person's constitution and tendencies.

Republic of Korea Patent No. 10-2260010 (2021.05.28)

The present invention was created to solve the above problems, and the purpose of the present invention is to collect and monitor the user's electrocardiogram, obtain the electrocardiogram waveform in a resting state, and reflect the resting electrocardiogram waveform obtained before sleep to generate sound waves.

The present invention helps users effectively relieve mental and physical fatigue by relieving stress while going to bed, making it easier to sleep, and improving sleep quality.

In particular, by using sound sources that reflect resting heart rate waveforms rather than drugs or methods that affect brain waves, anyone can use them without any side effects or resistance, and the choice of sound sources is wide and more accurate customized care can be provided through the monitoring and feedback process. You can.

Figure 2 is a block diagram showing the configuration and connection relationship according to an embodiment of the present invention.

Hereinafter, the configuration of the stress relief system for improving sleep quality of the present invention will be described in detail with reference to the attached drawings.

Figure 1 is a conceptual diagram of the present invention. The present invention supports mental stability and stress relief by listening to sound sources optimized by reflecting the heart rate of the user's mental stability before sleep, and not only induces sleep but also improves the quality of sleep. .

Figure 2 is a block diagram showing the configuration and connection relationship according to an embodiment of the present invention. The main components for this purpose are a measurement module 110, an analysis module 120, a sound source management module 130, In addition to the sound source processing module 140 and the output module 150, it is equipped with a monitoring module 160 and a feedback module 170 to improve the effect.

The measurement module 110 is configured to measure the user's electrocardiogram signal, and is configured to be held in the user's hand or worn or attached to the body, for example, the wrist or various parts where electrocardiogram measurement is possible, so that the user can use it. It is configured to obtain an electrocardiogram signal. In particular, in the present invention, since it is mainly used intensively before sleep to improve sleep quality, the measurement module 110 is provided at the user's sleeping place.

The ECG signal is obtained by guiding the active current generated in the myocardium according to the heartbeat to two appropriate locations on the body surface and recording it with an ammeter, thereby obtaining a record of the myocardial active current. In particular, in the present invention, the ECG waveform in the measured ECG signal is very It acts as an important factor.

Figure 1 contains a graph showing a typical electrocardiogram waveform, where P in the curve represents contraction of the atrium, and QRST originates from contraction of the ventricle.

At this time, the PQ interval represents the time when excitation occurs in the sinus node and is conducted to the atrioventricular node of the impulse conduction system.

In addition, the QRS complex usually coincides temporally with the apex beat and the beginning of the first heart sound, so R shows the largest voltage change, and the area between S and T is when the entire ventricle is contracting on average. The rise of the T occurs because contraction of the base of the heart remains even after contraction of the apex has ended. The end of T coincides temporally with the beginning of the second heart sound.

The analysis module 120 collects and analyzes waveform information including the amplitude and frequency of the heartbeat through the measured electrocardiogram signal and extracts waveform information of the psychological stabilizer.

In order to obtain an ECG signal in a stable state or as close to it as possible, it is necessary to obtain an ECG signal that is judged to be in the most stable state through multiple measurements over a period of time when the stress source is removed, rather than a one-time measurement.

For this purpose, the electrocardiogram signal is continuously measured in the absence of stress sources or removed as much as possible in advance, and heart information is also input, or the autonomic nervous system measurement equipment is used to measure continuously for a set period of time, and then based on the heart rate variability (HRV). The balance of autonomic nervous system (Balance of Autonomic Nervous System) can be quantified using the standard derivation method and the value expressed can be used as mental information. ECG waveform information is extracted from the ECG signal in the psychologically stable state.

The sound source management module 130 receives and stores sound sources to be used for stress relief, and includes a sound wave generator 131 and a sound source storage unit 132 in detail.

The sound wave generator 131 is configured to generate sound waves with the same sound wave characteristics by extracting feature vectors for the amplitude and frequency of the waveform information of the stabilizer. That is, through analysis of changes in the normal rhythm P-QRS-T waveform of the electrocardiogram in the user's resting state, feature vectors for amplitude and frequency are extracted and converted to the same sound wave.

The sound source storage unit 132 is configured to receive and store a plurality of sound sources having a BPM in a set range, and can receive and utilize sound sources such as various music or natural sounds that can provide mental and physical stability in advance. In particular, a sound source with the same BPM as the resting heart rate is effective, so it is possible to artificially adjust the speed of a specific sound source to have a specific BPM, but it is preferable to collect and store a separate sound source with the corresponding BPM if possible.

That is, since the range of a person's normal heart rate is 60 to 100 beats per minute, a number of sound sources with BPMs in the range are received based on this.

It can be configured to provide and manage sound source information including scale, chords, chord progression, and instruments that make up the sound source, and receive recommendations from advance experts for sound sources suitable for the set sound source information or systematically exclude sound sources that are unsuitable for the sound source information. It can also be configured to do so.

This is to provide music with an optimal effect as the scale of the music, chords and chord progression, and instruments can affect the stress relieving effect. In the embodiment of the present invention, repetitive G-C-D-G in 4/4 time. Although keyboard and guitar ensemble music was used as a rhythm pattern composed of chords, it is natural that sound sources with various characteristics can be used.

Scale used in sound sources refers to the arrangement of a certain note to a note one octave higher. The notes used change depending on the scale used when making music, and the atmosphere is determined accordingly. Most music we listen to uses the Ionian scale or Aeolian scale, which are called the major scale and minor scale, respectively.

This means that the music most familiar to our ears is created using the two scales immediately above. Music in the major scale creates a bright atmosphere, and music in the minor scale creates a dark atmosphere. Healing beat's music uses Major Scale to create a bright atmosphere that is familiar to our ears.

The chord used is called a Diatonic Chord, as it is created by stacking each note of the scale mentioned above. Since it is a code created using notes belonging to a scale, it can be said that there is no sense of heterogeneity in a given scale. Healing beat uses music composed based on the G Major scale, and the corresponding diatonic chords are G, Am, Bm, C, D, Em, F#m7(b5). Among them, excluding F#m7 (b5), which can be said to be unstable in composition, it was made using the remaining six chords.

The chord progression of 1-6-4-5 is a type that can be easily found in many songs, and the most common progression that people can easily listen to is used. The Bridge section also uses the commonly seen progression of 4-5-3-6 degrees and the progression of 2-1-4-5 degrees to select the most natural progression within the Diatonic Chord. The 1-6-4-5 progression from earlier appears again, ending the song with a familiar feeling.

Use music composed so that the progression of the melody is sufficiently predictable, and avoid using excessive jumps (more than 8 degrees) or notes that are not included in the scale. Progression to the fourth degree, which can cause anxiety, is also excluded.

It was composed to be easy to listen to using mainly sequential progression (ascending, descending), and an appropriate speed must be maintained to increase the BPM from 60 to 100, but the use of eighth notes mainly makes the song feel like it is stretching or is too fast. Avoid feeling it.

The choice of instrument is guitar and piano, which are the most easily accessible instruments around. The piano is used to play the background with chords, and the melody is played on top of the guitar.

The sound source processing module 140 extracts a sound source identical to the BPM according to the waveform information of the psychological stabilizer from the sound source storage unit 132 in accordance with the set bedtime, and then generates the searched sound source through the sound wave generator 131. It is a configuration that reflects and processes sound wave information.

That is, basically, a song is selected whose heart rate BPM of the user's psychological stability matches the BPM of the sound source in the sound source storage unit 132, and the extracted sound source is converted into a sound wave generated through the sound wave generator 131. It is reflected and processed so that the sound wave characteristics of the sound source are the same as the sound wave extracted from the feature vector of the user's resting heart rate waveform.

The output module 150 operates to relieve stress through a sound source, and includes an output unit 151 and a timer unit 152 in detail.

The output unit 151 is configured to correspond to a speaker and may operate in conjunction with a separate speaker or audio system installed so that the user can listen, and the user can listen to the sound source processed through the sound source processing module 140. The output is output at an appropriate volume level.

The timer unit 152 is configured to set and control the bedtime and sound source output time. Basically, it allows the user to listen to the sound source 10 to 20 minutes before going to bed, preferably 15 minutes before, but especially while listening to the sound source. It is configured so that the user can set the time so that sound source playback stops after a set time even when entering sleep.

The present invention applies a beat induction intervention program using beats and sound waves, called the Healing Beat Program, before sleep time to improve sleep quality, and provides waveform characteristics identical to the electrocardiogram waveform at rest to users exposed to various stressors during the day before sleep. By outputting a sound source and inducing calming, the stress-relieving effect through this sound source can be proven through various research papers in which the present inventor participated.

The monitoring module 160 is configured to control the playback time and volume of the sound source as the user enters a sleep state while listening to the aforementioned sound source, induce deeper sleep, and improve sleep quality. The detailed configuration includes the first part. It is provided with a tracking unit 161 and a control unit 162.

The first tracking unit 161 is a component that analyzes real-time changes in the electrocardiogram signal collected through the measurement module 110 during the operation time of the output module. In other words, when entering sleep normally, the electrocardiogram changes are alleviated to the same extent as during sleep.

ECG changes during sleep may vary slightly depending on the person, but basically, it is common for it to gradually decrease until deep sleep and then gradually recover until waking up, or to continue to decrease until waking up, depending on the case. It may rise for a certain period of time if you deviate from the normal pattern and go to bed late or if melatonin is initially secreted excessively to help you sleep. Preferably, the individual's heart rate during stable sleep is measured in advance and applied, or compared with the resting electrocardiogram to determine that sleep is progressing. If an unstable electrocardiogram appears in the case of a dream or REM sleep disorder, it is necessary to continuously secure the playback time of the sound source even during actual sleep.

The control unit 162 is configured to control the sound source output time to be reset and the volume fade-out change corresponding to the reset output time by reflecting the change rate when it is determined that the sleep progress range is stable as a result of electrocardiogram signal analysis.

In other words, playing a sound source with the volume not properly controlled when entering sleep may actually interfere with improving the quality of sleep. Therefore, when entering a stable sleep state is confirmed through the first tracker 161, the sound source is played by gradually reducing the volume. and ensure stable sleep continues.

At this time, if rapid stabilization is achieved by reflecting the speed of ECG change, the volume should fade out and the sound source playback should be stopped within a short period of time. If slow stabilization is achieved, the volume should be faded out and the sound source playback should be stopped over a relatively long period of time. There is. In other words, a slow stabilization speed means that it takes more time to fall asleep, which means that there is a high risk of being easily awakened by changes in the surrounding environment in a sensitive state.

Accordingly, it is desirable to apply a set time equal to or proportional to the time from the beginning of sound source playback to the time when the ECG signal is stabilized, fade out the volume over the set time, and stop playback of the sound source when the final volume becomes 0. do.

In addition, after applying the present invention, a feedback module 170 may be provided to receive feedback from the user on aspects related to improving sleep quality and correct the conditions by finding the optimal sound source in the setting range, and the evaluation unit 171 may be configured in detail. ), a second tracking unit 172, and a calculating unit 173.

The evaluation unit 171 is configured to receive evaluation information from the user after use. It allows questions and responses on a 3 to 10 point scale, and can receive evaluation information through a linked web or application.

The main questions are: how many times did you wake up during sleep, how much did you move during sleep, total sleep time from the moment you lay down to sleep until you woke up, the depth of sleep you felt, how long did it take from the moment you lay down to fall asleep, how long did you sleep? An evaluation of your sleep, including how you felt when you woke up and whether you woke up on your own or was woken up by someone else, is entered as a subjective numeric indicator, and whether a positive or negative evaluation was made is determined based on the midpoint of the overall score.

The second tracking unit 172 maintains the waveform information when the evaluation information is positive, and generates and outputs a converted sound source that applies the BPM and sound wave characteristics in the upper and lower ranges to the sound source output when the evaluation information is negative. It is a configuration that collects real-time changes in the electrocardiogram signal collected through the measurement module.

That is, if it is a sound source that normally reflects sound waves according to the resting ECG waveform, the ECG changes will quickly stabilize, so a converted sound source is generated by applying the BPM and sound wave characteristics in the upper and lower ranges to the sound source output through the output unit 151. and output, and correspondingly collect real-time changes in the electrocardiogram signal collected through the measurement module 110.

The calculation unit 173 analyzes the collection results of the second tracking unit 172 and calculates a sound source corresponding to the waveform information of the real-time electrocardiogram signal stabilizer.

In other words, as it may be difficult to create a situation in which there is no initial stress, supplementation can be made so that an optimized sound source can be found later through the feedback module 170.

The rights of the present invention are not limited to the embodiments described above but are defined by the claims, and those skilled in the art can make various changes and modifications within the scope of the claims. This is self-evident.
