It is noted that the terms used herein should be interpreted as having a meaning that is consistent with the context of this specification and should not be interpreted in an idealized or overly formal sense.

The first embodiment is as follows:

as shown in fig. 1, an embodiment of the present application provides a method for estimating a relaxation state of a body, including the following steps:

carrying out relaxation training according to the relaxation training model to obtain a training respiratory waveform;

In the above scheme, before starting the relaxation training, it is necessary to prepare the equipment related to the relaxation training, which is specifically as follows:

seat or lying furniture for relaxation training: the patient needs a relatively comfortable physical environment for the return training to well stretch the body, and sitting or lying down can help the patient to better find the corresponding physical environment. As shown in fig. 2, the seat 101 includes a backrest, a base, and side arm portions so that the patient can have a better "wrapped feeling" when sitting, which is similar to the feeling that an infant is wrapped in the placenta before birth, and can be more relaxed.

In order to collect data of the user during relaxation, it is necessary to mount a vibration sensor on the seat, which may be mounted at the first area 101A or at the second area 102B of the seat 101. The vibration sensor comprises an acceleration sensor, a pressure sensor and a displacement sensor or a sensor which is equivalently converted by taking acceleration, pressure and displacement as basic physical quantities, and the vibration sensor adopts a light ray sensor.

In addition, the seat 101 is further provided with a display device 103, which can be a notebook, a tablet, a mobile phone, etc., without limitation, and can input the identity information, the training information, etc. of the user through the display device, so that the user can find his own training information in time; as shown in fig. 3, the seat 101 further includes a backrest 201A and a foot supporting plate 201B, the angle of the user sitting on the seat 101 can be adjusted by adjusting the backrest 201A, and the angles of the two legs can be adjusted by adjusting the foot supporting plate 201B, so as to help the user find a more comfortable state, wherein the adjustment methods of the backrest 201A and the foot supporting plate 201B are not limited herein, and may be manual adjustment or electric adjustment.

It should be noted that, in the present application, there is no requirement for the structural form of the seat or the sliding tool, as long as a person can perform relaxation training on the seat and obtain related data.

After the preparation work is finished, the user selects a relaxation training model suitable for the user as required, and the relaxation training module comprises: voice guidance, music therapy, VR therapy, binaural beat therapy, and the like. After the relaxation training model is selected, the corresponding reference respiration waveform can be obtained according to the training model.

The user then merely sits on the seat with or without the earphones 104, and is in a separate, relatively quiet environment where the music is played out, such as by sound. In the training process, a patient does not need to do any operation, only needs to follow a training model, such as voice guidance, and relaxes the body and mind in an immersive mode as much as possible, while the vibration sensor always collects data in the process that the user is not prepared and burdened, and actually calculates related parameters for evaluating the relaxation state of the user.

As shown in fig. 4, the training respiratory waveform acquired by the vibration sensor in the second region 102B during exercise of the user is shown, in the figure, the large contour is a signal envelope generated during the exhalation process and the inhalation process of the user, and the heart beat and other interference noise are superimposed on a respiratory envelope curve, at this time, the respiratory signal waveform related to the actual exhalation process and the inhalation process of the user is directly acquired based on the respiratory envelope curve, that is, the data acquired by the vibration sensor is directly preprocessed to capture the signal within the required bandwidth range (0-2 HZ) of the calculated respiratory waveform, and the preprocessing method may be one or more combinations of filtering methods such as an IIR filter, an FIR filter, a wavelet filter, a zero-phase bidirectional filter, a mean value filter, and a smoothing filter.

As shown in fig. 5, the training respiratory waveform obtained by performing the low-pass filtering process on fig. 4 with an IIR filter is shown. The utility model provides an optical fiber sensor is adopted to vibration sensor, the sensitive pressure variation that vibration displacement change arouses, the user exhales the position relation system of pressure variation and vibration sensor that the process arouses with the process of breathing in, the position that vibration sensor installed on thing to sit on 101 is different, can lead to the training breathing waveform that produces different, vibration sensor is arranged in the second area 102B in this embodiment, user's buttock below promptly, when the user breathes in, the chest abdominal cavity is carried the gas and is expanded, lead to the health to be in the state of pushing down, for the increase trend to bottom pressure variation, for the falling edge interval in the training breathing waveform, the rising interval in the breathing waveform is then untrained to the expiratory state.

For convenience of description, the mode for guiding the patient's breathing is not configured in this embodiment as the simplest fixed breathing frequency mode with reference to the state set of the beard waveform, and is configured as a training "fast deep inhalation slow deep exhalation" mode, where the inhalation time interval is configured as T1, the exhalation time interval is configured as T2, and the cycle is repeated, generally, the patient needs to inhale fast and deeply, and exhale slowly, that is, the exhalation time interval is set to be T2 greater than the inhalation time interval as T1, and in this embodiment, the exhalation time interval as T2 is about twice as long as the inhalation time interval as T1. As shown in fig. 6, the uppermost solid square wave is a reference respiratory waveform, the low state value indicates a guiding inspiratory state, the high state value indicates a guiding expiratory state, the user performs expiration and inspiration along with voice guidance during training, the vibration sensor records the respiratory state of the user, the recorded data is a waveform diagram of the middle position, for convenience of presentation, the waveform diagrams of the middle position are two, one is a training respiratory waveform obtained by original training respiration, the other is a formed waveform obtained by filtering the original data, a real training respiratory waveform after training can be calculated by the waveform, and the lowermost square wave is a training respiratory waveform in a square waveform form obtained according to the training respiratory waveform after filtering processing in the middle. Similarly, a low state value indicates a leading inspiratory state and a high state value indicates a leading expiratory state; wherein the gray filled-in module represents the time difference during inspiration that the actual inspiration is earlier or later than the end of the reference inspiration, and the black filled-in module represents the time difference during expiration that the actual expiration is earlier or later than the end of the reference expiration.

Then calculating a breath matching index between the reference breath waveform and the training breath waveform according to the reference breath waveform and the training breath waveform, wherein the breath matching index comprises an expiration matching index and an inspiration matching index; the mental pressure index is calculated according to the breathing frequency in the training breathing waveform, the relaxation state of the body is comprehensively evaluated according to whether the obtained breathing matching index is located in a preset expiration matching index interval or not and whether the obtained breathing matching index is located in a preset mental pressure index interval or not, for example, the preset breathing matching index interval is 0.2-0.5 and the preset mental pressure index interval is 0.1-0.3, whether the user is in the relaxation state or not is judged through the breathing matching index and the mental pressure index together, the user is not judged to be more relaxed only through the higher breathing matching index, the user is not relaxed through the lower mental pressure index, and the breathing matching index obtained through the relaxation training of the user is not high, each time of expiration is delayed by a certain time compared with the training model, but the user is probably in the most relaxed state, and the user is easy to be misjudged if the relaxation state is judged only through the breathing matching index.

The body in the present application refers to a user using the method or apparatus in the present application.

Therefore, according to the body relaxation state evaluation method provided by the application, firstly, a user selects a relaxation training model to obtain a reference respiration waveform, then the user trains the relaxation training model to obtain a training respiration waveform, and according to the obtained reference respiration waveform and the training respiration waveform, the respiration matching index between the reference respiration waveform and the training respiration waveform, the mental stress index of the user, the comprehensive respiration matching index and the mental stress index are calculated to evaluate the relaxation state of the body, so that the fine state of the user in the inspiration and expiration processes is combined, and the relaxation state of the user is more comprehensively and accurately evaluated.

and calculating a breath matching index according to the difference duration.

and calculating to obtain the breath matching index according to the mapping relation.

In the above scheme, the respiratory matching index substantially refers to the matching degree between the reference respiratory waveform and the training respiratory waveform, and the specific calculation method is as follows:

as shown in fig. 6, the gray filled blocks represent the time difference during inspiration that the actual inspiration is earlier or later than the end of the reference inspiration, and the black filled blocks represent the time difference during expiration that the actual expiration is earlier or later than the end of the reference expiration; adding the corresponding time lengths of all the gray filling modules to be used as inspiration difference time length, and then calculating corresponding inspiration matching indexes according to the ratio of the inspiration difference time length to the integral time length of the reference respiration waveform or according to the difference time length through methods such as a functional relation and the like; after the difference duration is obtained, a mapping relation can be established between the difference duration and the inspiration matching index, for example, the difference duration is 0.1, the corresponding inspiration matching index is 1, the inspiration matching index can be obtained through the method, and in addition, the corresponding difference area, volume and the like can be calculated through the inspiration difference duration to obtain the corresponding inspiration matching index.

Similarly, the corresponding durations of all the black filling modules are added to be used as the expiration difference duration, and then the corresponding expiration matching index is calculated according to the ratio of the expiration difference duration to the overall duration of the reference respiration waveform or according to the difference duration through methods such as a functional relation and the like; after the difference duration is obtained, a mapping relation can be established between the difference duration and the expiration matching index, if the difference duration is 0.1, and the corresponding expiration matching index is 1, the expiration matching index can be obtained through the method, and in addition, the corresponding difference area, volume and the like can be calculated through the expiration difference duration to obtain the corresponding expiration matching index.

If only the inspiration process is concerned, only an inspiration matching index model can be evaluated and established to represent the breathing matching index evaluation training effect; if only the exhalation process is concerned, the exhalation matching index model can be only evaluated and established to evaluate and characterize the training effect of the breathing matching index. Of course, the two processes can be considered simultaneously, and the breathing matching index model is evaluated and established by considering the inspiration process and the expiration process simultaneously, so as to represent the training effect of the breathing matching index evaluation. In one embodiment, different attention weights are possible for the inspiration process and the expiration process, and the respiratory matching index model can be established through a weight distribution function. Further, the difference duration, the ratio of the difference duration to the training duration, the ratio of the difference duration to the overlap duration, and the relationship between the difference durations and the training durations, which can be converted with each other, may all establish a mapping relationship corresponding to the breath matching index, which is not described in detail.

After the training respiratory waveform is obtained, respiratory parameters such as respiratory frequency and respiratory mode of the training respiratory waveform can be calculated and obtained through various methods such as a time domain wave searching method, a morphology matching method and a time-frequency analysis method, and then mental stress indexes are calculated through the respiratory parameters, wherein if the respiratory frequency is higher, the mental stress is higher, and if the respiratory frequency is lower and tends to be stable, the mental stress is lower.

The mental stress index of the body can be calculated according to training heart rate parameters of the user, such as heart rate, heart rate variability and other parameters, obtained by the vibration sensor after the user performs relaxation training.

The mental stress index of the body can be calculated according to the comprehensive breathing parameter and heart rate parameter.

In the application, the heart rate variability is used for calculation, the synergistic effect of the sympathetic nerve and the parasympathetic nerve of the autonomic nervous system is reflected, the function and the balance capability of the autonomic nervous system are represented, and the mental state of a patient can be reflected. There are many analysis methods for heart rate variability, including linear analysis methods and nonlinear analysis methods, and linear analysis methods also include time domain analysis methods, frequency domain analysis methods, transfer function analysis methods, and the like. In this embodiment, a frequency domain analysis method is adopted, and based on the obtained time domain BCG signal waveform, a beat-to-beat heart beat width sequence is obtained by a wave searching method, and a heart beat width sequence of a certain time length (2 minutes in this embodiment) is taken for power spectrum analysis. The power spectrum can be obtained by using methods such as Fourier transform, welch spectrum method, AR spectrum estimation and the like. In the embodiment, an AR spectrum estimation method is adopted, then spectrum division is carried out, and high-frequency components HF are classified into groups of 0.15 to 0.40Hz, low-frequency components LF are classified into groups of 0.04 to 0.15Hz, and ultra-low-frequency components VLF are classified into groups of 0.003 to 0.04Hz. An energy ratio LF/HF of the low frequency component to the high frequency component is calculated, which reflects the state of equilibrium of the autonomic nervous system, to thereby map the Stress index Stress (HRV (t)), HRV (t) = HRV ((LF/HF) (t)). Further, in one embodiment, the Stress index Stress (HRV (t)), HRV (t) = HRV ((LF/HF) (t), TP (t)) may be corrected in combination with the total power spectrum TP.

Example two:

the second embodiment of the present application provides a method for adjusting a body relaxation state, including the following steps:

executing the assessment method of the body relaxation state;

In the above scheme, after the organism passes the relaxation training, the calculated breath matching index is located outside the preset breath matching index interval, the organism needs to be adjusted, and the breath matching index is adjusted to the preset breath matching index interval, and the specific adjustment method is as follows:

the last two black filled blocks are very small in area as shown in fig. 6. And the gray filling blocks still exist, but both gray filling blocks are provided with the inspiration end position, namely the expiration start position later than the reference respiration waveform, so that the voice guidance can generate an adjusted relaxed training guidance model according to the characteristic self-adaptive update, the inspiration time ratio is slightly lengthened, namely, the inspiration time interval T1 is adjusted to be T1+ delta T, the expiration time interval is T2-delta T, and the delta T is larger than 0 and is adjusted according to the patient adaptation time difference. Of course, the adjustment cannot be blindly adjusted, otherwise, the patient's own unscientific breathing pattern may be matched, and the fine adjustment must be carried out by properly matching the breathing fluctuation rhythm of the patient on the premise of the scientific breathing pattern approved by medical staff. In the embodiment, the allowable adjustment range is configured such that after the inspiration time interval T1 is adjusted to T1+ Δ T, the time interval of 70% of the expiration time interval T2- Δ T still cannot be exceeded, so as to ensure the training status of fast deep inspiration and slow expiration.

In one embodiment, the mode configured to guide the patient's breathing is a training "slow deep inspiration slow deep expiration" mode, and the adjusted T1+ Δ T may be limited to a range of (T2- Δ T) × 80% - (T2- Δ T) × 120%. In one embodiment, the mode configured to guide the patient's breathing is a training "slow deep inhalation, fast deep exhalation" mode, and the adjusted T1+ Δ T may be limited to be no less than (T2- Δ T) × 150%.

In particular, due to differences in the acuteness of reflex actions made by the patient in the relaxation training guided by the reference respiratory waveform, for example, the body has a lag in the transition from the inspiration state to the expiration state corresponding to the guidance instruction, and although not matched with the reference respiratory waveform, the current state may be the most comfortable and relaxed state of the body.

It should be noted that, in the present application, the relaxed state of the body can be adjusted by adjusting the inspiration time or the expiration time alone, and the adjustment can be performed by adjusting the inspiration time and the expiration time simultaneously, which is not limited herein.

After the body passes the relaxation training, the calculated mental stress index is outside the preset mental stress index interval, the body needs to be adjusted, and the mental stress index is adjusted to the preset mental stress index interval, wherein the specific adjustment method comprises the following steps:

in this embodiment, at a certain time T1 during the respiratory training, the inspiration time interval is T1 (T1), the expiration time interval is T2 (T1), and the Stress index is Stress (T1). At this time, if an adjustment is made to Δ T (T1), Δ T (T1) >0, for the respiratory matching state of the patient, at the next time T2, the inspiration time interval is T1 (T2) = T1 (T1) + Δ T (T1), the expiration time interval is T2 (T2) = T1 (T1) - Δ T (T1), and the Stress index is Stress (T2). In this case, the deviation Δ Stress (t 2) between Stress (t 2) and Stress (t 1) can be determined. If Δ Stress (T2) is greater than 0, indicating that the direction of adjustment may adversely affect the patient's own relaxation state, and therefore- Δ T (T2), Δ T (T2) >0, can be adjusted in reverse, then at the next time T3, the inspiration time interval is T1 (T3) = T1 (T2) - Δ T (T2), the expiration time interval is T2 (T3) = T1 (T2) + Δ T (T2), and the Stress index is Stress (T3). At this time, the deviation value Δ Stress (t 3) between Stress (t 3) and Stress (t 2) can be judged, and Δ Stress (t 3) is found to be less than 0, which indicates that the adjustment direction is accurate and further adjustment can be performed. The above steps are repeated in a cycle, so that a relaxation training guide model which is best fit with the current patient can be found in the current breathing mode. In one embodiment, when Δ Stress (t 2) is found to be greater than 0, Δ t (t 2) >0, which is adjusted in the reverse direction, may also ensure that Δ t (t 2) > Δ t (t 1) >0, to reach the equilibrium point more quickly.

Preferably, the breath matching index and mental stress index can also be adjusted by adjusting the breath depth, such as adjusting the frequency of expiration and inspiration in the breath depth, 10 breaths in 1 minute, 5 breaths out, and the like.

Therefore, by the method for adjusting the body relaxation state, the breath of the user can be adjusted in time according to the estimated relaxation result in real time, the breath matching index and the mental stress index are updated continuously in time to form annular feedback, so that the user can obtain good relaxation training and is in the relaxation state as far as possible, and the user is helped to find a proper relaxation training method.
