Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1: respiratory waves induced by vital activity: the duration of the first breathing manoeuvre is T1, the duration of the second breathing manoeuvre is T2, the duration of the third breathing manoeuvre is T3 and so on without further illustrating the exhaust. Wherein the time period of inspiration in the first breathing manoeuvre is t11 and the time period of expiration in the first breathing manoeuvre is t 12; the duration of inspiration in the second breathing manoeuvre is t21, the duration of expiration in the second breathing manoeuvre is t22, and so on without further illustration of the exhaustion. Corresponding to an inspiratory phase within t11 time of inspiration in the first breathing action, wherein the pressure in the chest cavity of the human body is negative pressure; the time period t12 of expiration in the first respiratory action corresponds to the expiratory phase, in which the pressure in the human chest is positive. When the human thorax is in a negative pressure state, the human muscle group is relatively tense, and when the human thorax is in a positive pressure state, the human muscle group is relatively relaxed and tends to relax. It should be noted that the respiratory wave shown in fig. 1 is obtained by the prior art vital signal collecting device after being collected instantly, and therefore, the technical details of the related signal acquisition are not further illustrated and described herein.

Through experimental study, the breathing rate of a normal human body is generally between 30 times per minute (2 seconds per time) and 5 times per minute (12 seconds per time) (including end points), 50 milliseconds are taken as a minimum time interval (in the following scheme, the minimum time interval is referred to as time resolution), the time length distribution is divided into 201 time periods with different time lengths from 2000ms to 12000ms, and 201 tidal sound files with the playing time lengths respectively consistent with the time periods are manufactured according to the different playing time lengths. For example: the playing time of the first tidal sound file is 2000ms, the playing time of the second tidal sound file is 2050ms, and the like until the playing time of the last tidal sound file is 12000 ms. And the 201 sound files are combined into a first sound file library. The playing volume of any sound file is from low to high and then is reduced to low, and the effect reflected on the hearing is from absent to present and then to absent.

Example 1:

in this embodiment, the file in the play control module calls rules, and full-wave acquisition is adopted to guide generation of playing sound of tide and tide. Experiments prove that under the action of the biological feedback type depth relaxation guide system, when the guide is repeatedly conducted for more than three times, the respiratory wave of the experiential person is synchronously coincided with the playing period of the tidal sound. Specifically, referring to fig. 2, the tidal sound playing curve shown in the lower part of fig. 2 includes three playing periods in total; as shown in the upper image of fig. 2, when the physiological information collecting module collects a respiratory wave signal with a first time duration of T1, the playing control module calls a tidal sound file with a playing time duration consistent with T1 from the first sound file library to play continuously three times; in this process, as shown in the upper image of fig. 2, the respiratory wave of the experiential person will gradually coincide with the playing period of the tidal sound synchronously, which is embodied that the total duration of T2, T3 and T4 is close to 3 times of T1; at this time, in order to ensure continuity of subsequent tidal sound playing, the playing control module averages the total durations of T2, T3 and T4 to further obtain a new playing and picking-up duration; the playing control module calls the tidal sound file with the playing time length consistent with the average value time length from the first sound file library to play continuously for three times; the respiratory wave of the experiential person will gradually coincide with the playing period of the tidal sound to obtain further synchronization, and further obtain T5, T6 and T7 (not shown in the figure); and repeating the average calculation and the playing operation of the corresponding tidal sound file until the tested person is guided to the super low wakefulness state or the sleep state.

Preferably, in one of the preferable technical solutions of this embodiment, each time the tidal sound file with three times and the same time duration is played, the voice prompt provided by the second sound file library for guiding the human body to relax is played synchronously. Preferably, the guidance information included in the voice prompt includes, but is not limited to, guidance of the attention of the subject to be distracted at various parts of the body.

It should be noted that, in the foregoing embodiment of the present application, the time resolution is not limited to 50ms, and an integral multiple of 50ms may also be used as the minimum time interval, and the tidal sound file with a corresponding duration is called from the first sound file library to be played, so as to obtain a use effect of low-resolution tidal sound guidance playing, and bring different comfort levels of relaxation guidance experience to a user. In addition, the number of times of playing the same tidal audio file each time by the playing control module is not limited to three times adopted in the above embodiment, and the number of times of playing is set to be more than or less than three times according to the requirements of a user, which is also claimed in the present application, but no matter the number of times of playing is set to be several times, the calculation method of the average duration remains unchanged, that is, the sum of the durations of the complete respiration waveforms of the corresponding times acquired by the vital signal acquisition device in the repeated playing duration range is subjected to quotient with the playing times, so as to obtain the corresponding average duration; the playing control module calls the corresponding times of the continuous playing of the tidal sound file with the playing duration consistent with the average value time duration obtained by calculation from the first sound file library; so reciprocating, the tested person is brought into a super low wakefulness state or a sleep state. Therefore, the application also claims the freely set playing mode.

Experiments prove that under the action of the biological feedback type depth relaxation guide system, when the guide is repeatedly conducted for more than three times, the respiratory wave of the experiential person is synchronously coincided with the playing period of the tidal sound. Since the playback time of the half-wave method is about half of the playback time of the full-wave method, it is necessary to further increase the number of sound files in the first sound file library, and further increase the number of tidal sound files (including end points, the number of files being 20 in total) whose playback time is between 1000ms and 1950ms with 50ms as the time resolution in the first sound file library.

Specifically, referring to fig. 3, the tidal sound playing curve shown in the lower part of fig. 3 totally includes four playing periods, and the played tidal sound file is played only in expiration; as shown in the upper image of fig. 3, when the physiological information collecting and processing module collects the first inspiratory respiratory wave signal with time duration t11, the playing control module extracts the tidal sound file with playing time duration t11 from the first sound file library to play once; the physiological information collecting and processing module synchronously collects the time length t21 of the second inspiration respiratory wave signal shown as the upper image of the picture in fig. 3 at the same time of playing, and when the collection is finished, the playing control module calls a tidal sound file with the playing time length t21 from the first sound file library and plays the tidal sound file when the expiration of the second inspiration respiratory wave signal begins, and the process is repeated in a circulating way until the tested person is guided to a super low wakefulness state or a sleep state.

Preferably, in one of the preferable technical solutions of this embodiment, each time the tidal file is played, a voice prompt for guiding the human body to relax is played synchronously. Preferably, the guidance information included in the voice guidance provided by the second sound file library includes, but is not limited to, guiding the attention of the subject to be diverted to various parts of the body.

Example 3:

Experiments prove that under the action of the biological feedback type depth relaxation guide system, when the guide is repeatedly conducted for more than three times, the respiratory wave of the experiential person is synchronously coincided with the playing period of the tidal sound. Since the playback time of the first half-wave method is about half of the playback time of the full-wave method, it is also necessary to further increase the number of sound files in the first sound file library in which the tidal sound files (including the end points, the number of files being 20 in total) having playback times between 1000ms and 1950ms with 50ms as the time resolution.

Specifically, referring to fig. 4, the tidal sound playing curve shown in the lower part of fig. 4 totally includes three playing periods, and the played tidal sound file is played only when inhaling; as shown in the upper image of fig. 4, when the physiological information collecting and processing module collects the first expiratory respiratory wave signal with time duration t12, the playing control module extracts the tidal sound file with playing time duration t12 from the first sound file library to play once; the physiological information collecting and processing module synchronously collects the time length t22 of the second expiration respiratory wave signal shown in the upper image of the figure 4 during the playing, and the playing control module calls the tidal sound file with the playing time length t22 from the first sound file library when the collection is finished, and plays the tidal sound file when the expiration of the second expiration respiratory wave signal is finished, so that the circulation is repeated until the tested person is guided to the super low-wakefulness state or the sleep state.
