Abstract
Description
Technical Field
[0001] The present invention relates to the field of sleep breathing detection, evaluation and auxiliary regulation, and in particular to a method, system and device for detecting, quantifying and auxiliary regulation of sleep respiratory muscle states. Background Art
[0002] Respiratory movement is the most basic behavior for human survival, and the driving force comes from the respiratory muscles; the respiratory muscles mainly include intercostal muscles, diaphragm, abdominal wall muscles, sternocleidomastoid muscles, back muscles, chest muscles, etc. Respiratory movement not only brings about changes in lung volume and pressure, but also causes changes in muscle behavior of the thorax, throat, mouth and nose. The physiological state and behavioral changes of respiratory muscles and respiratory-related link organs have very good respiratory dynamics. In addition, events or phenomena such as obstructive sleep apnea, hypopnea, snoring, etc. caused by narrowing and obstruction of the upper airway are accompanied by vibrations of multiple parts such as the oropharynx, soft palate, and mandible; while central sleep apnea is accompanied by abnormal chest and abdominal breathing behavior, and chest and abdominal breathing is also the main breathing mode during sleep; the above events or phenomena not only directly lead to frequent intermittent hypoxia at night, but also damage sleep structure and sleep quality, and indirectly have different degrees of impact on people's quality of life and work, physical health and life safety.
[0003] The prior art solution CN116013470A relates to a method, system and device for dynamically adjusting the level of active sleep behavior: a method for dynamically adjusting the level of active sleep behavior is provided, which collects and processes the physiological state signals and behavioral state signals of the user's sleep process in real time, generates real-time characteristics of physiological and behavioral states, identifies the sleep phase state in real time and generates a sleep phase curve; performs real-time behavioral ability quantitative analysis, baseline change analysis and extreme value harmonic analysis on the real-time characteristics of physiological and behavioral states, generates real-time indexes of muscle tension level, central motor ability and behavioral action level; performs real-time baseline change analysis and extreme value harmonic analysis based on the above indexes, generates a real-time curve of active sleep behavior level, predicts and generates a trend curve of active sleep behavior level, generates a dynamic adjustment strategy for active sleep behavior level in real time and adjusts it dynamically, generates a sleep behavior active level adjustment report and establishes a personalized behavior adjustment long-term database. The invention realizes the scientific detection, evaluation and training of the active or inhibited level of sleep behavior; however, the technical solution does not specifically involve the identification and extraction of muscle state dynamic characteristics, the identification and detection of sleep breathing events, the calculation and extraction of event intensity, and the regulation and control of sleep breathing.
[0004] In general, the detection, analysis and evaluation of sleep breathing in the existing technical solutions mainly rely on polysomnography (PSG), which identifies respiratory event detection and event types through traditional respiratory signal waveform analysis such as oral and nasal pressure, thermal sensitivity and chest and abdominal belt pressure, and further completes simple statistical analysis such as hypopnea index and number of respiratory events. The existing technical solutions lack systematic and scientific detection, analysis and evaluation of the process characteristics, state events and occurrence and development of the sleep respiratory muscle state, especially lacking a clear definition or characteristic quantification of the intensity of sleep respiratory events from the perspective of respiratory dynamics. In addition, in the existing technical solutions and existing application scenarios, sleep breathing control equipment is usually separated from sleep breathing detection equipment. Most sleep breathing control equipment can feedback control parameters online but still use offline preset program control to complete device feedback control, making it difficult to perform intelligent, accurate and personalized dynamic auxiliary adjustment according to the user's real-time status.
[0005] From the above, we can see that how to systematically and scientifically detect, quantify and evaluate the process characteristics, state events and occurrence and development of the sleep respiratory muscle state, and further optimize and improve the efficiency and effectiveness of existing sleep breathing control equipment, so as to assist users' sleep breathing and improve sleep quality, is a problem that needs to be further solved in current domestic and foreign product technical solutions and actual application scenarios.

[0131] In this embodiment, signal fusion specifically involves synchronously averaging or delaying averaging different component signals from the same signal source to fuse them into one source signal.
[0132] In this embodiment, the sleep respiratory muscle state dynamics signal at least includes an electromyography envelope signal, a skin electrical SCL level signal, and a skin electrical SCR level signal.
[0133] The first step is to decompose the sleep muscle state signal to obtain a set of sleep muscle state description signals.
[0134] In this embodiment, a variational mode decomposition method is selected to perform signal decomposition on each signal in the sleeping muscle state signal.
[0135] In actual applications, the combined use of methods such as empirical mode decomposition (EMD), variational mode decomposition (VMD), blind source separation (BSS), independent component analysis (ICA), principal component analysis (PCA) and their evolutionary variants can meet the signal decomposition needs of different user scenarios.
[0136] The second step is to perform signal recognition on the sleep muscle state description signal set to obtain the sleep muscle state dynamics description signal set.
[0137] In this embodiment, first, the scaled electromyographic data of breathing, swallowing, clenching / grinding / chewing, head movement, and body movement are learned and modeled by machine learning to build an electromyographic source identification model. Then, by pre-building a machine learning model-electromyographic source identification model, the signal components of different sources such as breathing, swallowing, clenching / grinding / chewing, head movement, and body movement are identified from the decomposed signal set of each source signal in the sleep muscle state description signal set. Finally, the signal marked with "breathing" is screened to obtain the sleep muscle state dynamics description signal set.
[0138] The third step is to perform signal fusion and / or envelope extraction on the sleep muscle state dynamics description signal set to obtain the sleep respiratory muscle state dynamics signal.
[0139] In this embodiment, first, the signals of the "breathing" mark of each source signal in the signal set describing the dynamics of the sleep muscle state are fused through signal fusion to obtain the pure breathing signal of each source signal; then, the envelope signal of these pure breathing signals is extracted by Hilbert transform to obtain the breathing envelope signal of each source signal; thirdly, one signal is selected from the signal sources of the oropharynx-four channels and the chest and abdomen-two channels, and one respiratory dynamics signal is obtained through signal fusion (linear addition) to obtain the sleep respiratory muscle state dynamics signal.
[0140] In actual application scenarios, the oropharyngeal-muscle state signal is more likely to detect and describe events or phenomena such as obstructive sleep apnea, hypopnea, and snoring; chest and abdominal breathing is also the main breathing pattern during sleep, and central sleep apnea is more likely to be detected and fully described from the chest and abdomen-muscle state signal and chest and abdomen breathing behavior abnormalities. The fusion analysis of the oropharyngeal-muscle state signal and the chest and abdomen-muscle state signal can more comprehensively describe the sleep breathing behavior process and various sleep breathing events.
[0141] P300: performing event detection and analysis on the sleep respiratory muscle state dynamics signal to obtain a sleep respiratory muscle state event, and further extracting event intensity in combination with the sleep movement position signal.
[0142] The first step is to perform event detection and analysis on the sleep respiratory muscle state dynamics signal, extract the basic event information, and obtain the sleep respiratory muscle state event.
[0143] In this embodiment, the event detection and analysis specifically performs waveform feature recognition and marker extraction on the sleep respiratory muscle state dynamics signal according to a preset sleep respiratory-muscle event knowledge base and / or a machine learning model to obtain the basic event information of the sleep respiratory muscle state event; the basic event information includes at least event type, start time, end time, duration, peak and valley values, and peak and valley time.
[0144] In this embodiment, the sleep respiratory muscle state event at least includes event type, start time, end time, duration, peak and valley values, peak and valley value time, and event intensity.
[0145] In this embodiment, the sleep respiratory muscle state dynamics signal and the sleep respiratory muscle state event scale sample data are trained and modeled by machine learning, and a sleep respiratory muscle state event recognition model is pre-built. In the application process, the sleep respiratory muscle state dynamics signal is subjected to event detection analysis and information annotation by the sleep respiratory muscle state event recognition model, so that the basic event information of the sleep respiratory muscle state event can be easily extracted.
[0146] The second step is to calculate the event intensity of the sleep respiratory muscle state event based on the sleep respiratory muscle state dynamics signal, the basic event information and the sleep movement position signal.
[0147] In this embodiment, the event intensity is specifically determined by the duration, start time, end time, peak and valley values, and relative time between the peak and valley values of the sleep respiratory muscle state event, as well as the characteristic amplitude change of the sleep respiratory muscle state.
[0148] In this embodiment, the calculation and generation method of event intensity is specifically as follows:
[0149] 1) Obtaining the start time, end time, duration, peak-to-valley value, and peak-to-valley value time of the sleep respiratory muscle state event, as well as the preset sleep respiratory muscle state dynamic signal threshold;
[0150] 2) calculating the relative change of the peak-to-valley value of the sleep respiratory muscle state event and the preset sleep respiratory muscle state dynamic signal threshold to obtain the peak-to-valley relative value;
[0151] 3) Calculate the linear slope according to the start time, peak-to-valley value and time at the peak-to-valley value of the sleep respiratory muscle state event to obtain the peak-to-valley front slope;
[0152] 4) Calculate the linear slope according to the end time, peak-to-valley value and time at the peak-to-valley value of the sleep respiratory muscle state event to obtain the peak-to-valley trailing edge slope;
[0153] 5) Extracting the sleeping angle and sleeping direction information according to the sleeping movement position signal, and extracting the sleeping position correction coefficient according to a preset sleeping position correction coefficient comparison table or a preset sleeping position correction calculation strategy;
[0154] 6) according to the signal source of the sleep respiratory muscle state dynamics, according to the preset dynamic signal source-correction coefficient comparison table, extract the dynamic signal source correction coefficient;
[0155] 7) The event intensity is obtained by numerically fusion calculation based on the duration of the sleep respiratory muscle state event, the relative value of the peak and valley, the leading slope of the peak and valley, the trailing slope of the peak and valley, the sleep position correction coefficient, and the correction coefficient of the dynamic signal source.
[0156] In this embodiment, the preset sleep respiratory muscle state dynamics signal threshold is the mean of the sleep respiratory muscle state dynamics signal (electromyographic envelope signal) in the non-sleep respiratory muscle state event interval. In actual use scenarios, the mean of the user's electromyographic envelope signal in a resting state can also be used as the preset sleep respiratory muscle state dynamics signal threshold. In this embodiment, 20%, 50%, 80%, 100%, 150%, 200%, 300%, 500%, 800%, and 1000% exceeding the preset sleep respiratory muscle state dynamics signal threshold are used as grading intervals (preset sleep respiratory muscle state event intensity grading rules) to determine the event level or signal threshold selection.
[0157] In this embodiment, a preset sleeping position correction calculation strategy is used: the coefficient of the supine 0° angle is 0.5, and the coefficient of the prone 180° angle is 1.0 for linear angle calculation; the coefficient of the left side lying is a constant of 0.95, the coefficient of the right side lying is a constant of 0.90, the coefficient of the supine is a constant of 0.85, and the coefficient of the prone is a constant of 1.0. By obtaining the user's different sleeping posture directions and sleeping posture angles, the sleeping position correction coefficient is directly converted and calculated. In actual application scenarios, different sleeping positions (directions and angles) have a very large impact on sleep breathing behavior, directly affecting the local muscle state, especially the respiratory muscles. For example, obstructive sleep apnea is very easy to cause in a supine lying posture, which can be alleviated by sleeping on the side, but sleeping on the side will bring compression to the chest or heart.
[0158] In this embodiment, the preset dynamic signal source-correction coefficient comparison table has a comparison relationship of: oropharyngeal signal -0.80, thoracic and abdominal signal -0.90, oropharyngeal thoracic and abdominal combined signal -1.00.
[0159] In this embodiment, two widely used event intensity calculation formulas are provided to illustrate the construction method of numerical fusion calculation. In the actual application process, the numerical combination calculation method of event intensity is selected according to the actual situation of different user scenarios.
