Description
Technical field
The invention belongs to sleep monitor field, more particularly to the system and method that a kind of sleep quality improves.
Background technology
Sleep is high-grade complex physiologic process needful for living things, the process be related to from nervous centralis to
The coordinate operation of each bodily tissue, to ensure being normally carried out for sleep.The sleep of high-quality is human body clear-headed
The precondition of abundant physical and good spirit is kept under state, and it is sleep disordered, it may cause a variety of
Disease.Therefore the assessment that objectifies to sleep quality, monitoring and relevant medical research to health state
It is significant, and the rational scheme patient not good to sleep quality can be formulated based on this enter
The effective treatment of row.
Research shows that the sleep procedure of the mankind mainly includes two classes after sleep stage is entered by regaining consciousness completely
The process that cycle alternation is carried out, is called fast quick-action eye phase (REM) and no rapid eye movement phase (NREM) respectively,
The two is all to constitute the essential part of complete sleep.Wherein, organ activity is promoted during REM
Sympathetic activation be in the ascendance, with rapid eye movement, muscular tone, heart rate rise and θ wave bands brain electricity
Ripple occurs being principal character, correspond to the important stage that individual memory is formed；And suppress organ during NREM
Activity parasympathetic nerve excitement be in the ascendance, loosened with whole body, breathe and heart rate slow down, δ wave band brains
Electric wave occurs being principal character, correspond to the important stage of individual fatigue recovery and energy storage.It is public at present
Think clinical sleep detection and by stages be known as polysomnogram (PSG) the one of method " goldstandard "
Class technology, it needs that a variety of instruments are used in combination while the multi-channal physiological in being slept the whole night to tester enters
Row record, includes brain electric (EEG), eye dynamic electric (EOG), jaw myoelectricity (EMG), mouth and nose air-flow
With blood oxygen saturation etc., then carry out sleep mode automatically by stages by computer, then by technical staff according to international
Standard is corrected.Generally, PSG technologies can be by sleep on the basis of REM and NREM, according to each
The characteristics of road signal, NREM is further subdivided into the 1-4 phases (S1-S4), wherein S1, S2 are collectively referred to as
Shallow to sleep the phase, S3, S4 are collectively referred to as the sound sleep phase (also referred to as slow wave sleep phase, SWS).However, collection PSG
Signal needs, in the affixed multiple electrodes in partes corporis humani position, to cause great inconvenience, also sleep can be caused to do
Disturb to influence really to record result；Other PSG measurement needs to click through on the ground for having special expensive device
OK, it is difficult to extend to general domestic medicine monitoring arts.Therefore, it is necessary to which other are more simple for research and utilization
Method with means with low cost to sleep progress by stages.
Brain wave is influenceed by outside noninvasive minimal irritation, so as to regulate and control to sleep quality, learned
Art research turns out to be effective means.It is now generally used for the more ripe method of brain minimal irritation
Mainly transcranial magnetic stimulation (TMS), the technology passes through cranium using the pulsed magnetic field produced in magnetic induction coil
Bone influences the cynapse film potential of neuron, causes faradic produce so as to change local nerve excitability
To improve sleep.But disadvantage is that it is using bulky coil and complicated excitation set, overall
Equipment price also costly, be not particularly suited for using in normal sleep procedure.In addition, usual
Application scenarios in, the monitoring of sleep and stimulation are still that the equipment for being taken as two class independences is used alone, hardly possible
Made a concerted effort with being formed, to sleep quality, not good patient does not have optimal treatment improvement.
In summary, a simple in construction, the sleep monitor equipment that operation is simple and cheap how is designed,
It is provided simultaneously with the function of progress by stages with stimulation of sleeping under sleep condition for user, realize pin

The HRV of the user is calculated according to the heart rate signal, and is obtained by frequency-domain analysis
The ratio of the HRV low frequency components and high fdrequency component；
It is to go back the fast quick-action eye phase according to the low frequency component and the sleep state of the ratio in judgement user of high fdrequency component
It is for the no rapid eye movement phase；
If the sleep state of user is the no rapid eye movement phase, moved according to the body that the body movement information obtains user
Amplitude and body dynamic frequency, and judge that the sleep state of user is slept to be shallow according to the dynamic amplitude of the body and body dynamic frequency
Phase is still the sound sleep phase.
8. the method that sleep quality as claimed in claim 7 improves, it is characterised in that described in the basis
It is still that non-rapid is moved the fast quick-action phase that the sleep state of the ratio in judgement user of low frequency component and high fdrequency component, which is,
The eye phase specifically includes：
Judge whether the ratio of the low frequency component and high fdrequency component is less than predetermined threshold value；
If more than or equal to predetermined threshold value, the sleep state of the user is the fast quick-action eye phase；
If less than predetermined threshold value, the sleep state of the user is the no rapid eye movement phase.
9. the method that sleep quality as claimed in claim 6 improves, it is characterised in that the control system
Main frame dynamically adjusts stimulation mode and the time of the electrical transcranial stimulation instrument according to the sleep state, to change
The sleep quality of kind user is specifically included：
When the sleep state of user is the no rapid eye movement phase, the once non-rapid is counted every preset time
Ratio shared by the dynamic eye interim sound sleep phase, when the ratio is less than preset ratio, is controlled described through cranium electricity thorn
Swash instrument to start the electrical transcranial stimulation of slow wave δ wave bands and continue 4~6min of stimulation, to improve the sleep matter of user
Amount；
When the sleep state of user is the fast quick-action eye phase, the electrical transcranial stimulation instrument is controlled to start θ wave bands
Electrical transcranial stimulation simultaneously continues stimulation 8~10 minutes, to coordinate the stage distinctive brain wave frequency to stimulate lifting user
In the sleep quality in the stage.
10. the method that sleep quality as claimed in claim 6 improves, it is characterised in that described to be pierced through cranium electricity
It is to exchange one kind in electric stimulating instrument with through cranium through cranium galvanic current stimulation instrument to swash instrument.
