Description
Technical field
It a kind of analyzes the present invention relates to a kind of medical monitoring equipment more particularly to for brain electricity and blood oxygen saturation monitoring
Intelligent medical monitoring device.
Background technology
Sleep apnea syndrome is a kind of common sleep disturbance, is the height of the major diseases such as hypertension, cerebral apoplexy
Danger influence factor, can cause sudden death, have 10% or so adult to be influenced by sleep apnea syndrome at present when serious,
It finds and treats sleep apnea to be of great significance early.On Vehicles Collected from Market there are no occur by monitor human body electroencephalogram and
The intelligent medical equipment of sleep apnea syndrome is observed and treated to heart rate signal.
Sleep is divided into NREM sleep (NREM) and rapid-eye-movement sleep by the international sleep criteria for classifying
(REM), under normal circumstances the NREM stages based on θ waves, referred to as slow wave sleep；The REM stages, also known as fast wave was slept based on α waves
Sleep (Rechtschaffen＆Kales,《Mankind's sleep stage standardizes term, technology and dividing system handbook》,1968).
Morisson F and Lavigne G et al. carries out research discovery by the brain electricity to patients with sleep apnea：Patient
EEG signals integral energy is basically unchanged in entire sleep procedure, but EEG signals frequency slows down--- brain electricity delay ratio
(δ+θ)/(alpha+beta) increases, and the variation in parietal bone and occipital area is especially pronounced, and delay ratio is caused to increase most significant factor
Be δ waves (1-4Hz) activity enhancing and α waves (8-13Hz) activity weaken (Morisson F＆Lavigne G＆Petit D.et al,
Spectral analysis ofwakefulness and REM sleep EEG in patients with sleep
apnoea syndrome.European Respiratory Journal,1998)；Svanborg E and Guilleminault
The research of C et al. finds that the δ wave activities of OSA patient enhance in entire cerebral cortex as it can be seen that and being presented in forehead region maximum
Energy (Svanborg E＆Guilleminault C, EEG frequency changes during sleep
apneas.Sleep,1996)；Hyun-Kwon L and Doo-Heum et al. are it has also been found that gyrus α waves subtract after on the right side of OSA brain in patients
Weak most apparent, θ waves (4-8Hz) also show activity in frontal lobe, top, temporal lobe and increase (Hyun-KwonL＆Doo-Heum P＆
Hyun-Sil S.et al,Comparison oflow resolution electromagnetic tomography
imaging between subjects with mild and severe obstructive sleep apnea
syndrome:a preliminary study.Psychiatry Investigation,2008).Finnigan S and
The research of Robertson I H finds the difference with sleep stage, and there is also differences for the brain Electrical change of sleep apnea patient
It is different：In the NREM stages, δ waves activity continues to increase with the degree of apnea；In the REM stages, δ wave activity is presented discontinuity and increases
Add, and its δ wave energy maximum value is less than NREM stages (Finnigan S＆Robertson I H, Resting EEG theta
power correlates with cognitive performance in healthy older
adults.Psychophysiology,2011).Brain wave rhythm variation when sleep apnea is as shown in table 1.
Brain Electrical change when the 1. sleep cerebral electricity rhythm and pace of moving things of table and sleep apnea
| Brain wave rhythm | Normal person | OSA patient respiratory halted states |
| δ(1-4Hz) | Do not have when awake, when sleep occurs | Showed increased, forehead are most notable |
| θ(4-8Hz) | Occur when sleepy | Frontal lobe, top, temporal lobe activity increase |
| α(8-13Hz) | It is awake to close the appearance of mesh state | Reduced activity, gyrus is most notable behind right side |
| β(13-30Hz) | Mesh appearance is closed in thinking, peace and quiet | Reduced activity |
1984, Guilleminault et al. find heart rate variability the characteristics of, it is indicated that obstructive sleep apnea meeting
Cause the cyclically-varying of heart rate：It will produce heart rate decline when apnea starts, Tissue Blood caused by anoxic after a period of time
Oxygen decline can cause brain microarousal, can stimulate expansion pharynx flesh contraction that respiratory function is made to restore, restore with microarousal and breathing
Occur, heart rate has apparent rapid raising, and breathing restores to reach normal condition after a period of time, and heart rate also gradually restores just
Often (Guilleminault C＆Connolly S＆Winkle R.et al, Cyclical variation ofthe heart
rate in sleep apnoea syndrome.Mechanisms,and usefulness of24h
electrocardiography as a screening technique.Lancet,1984).Heart rate measurement can use light
Near infrared light skin is received the light intensity for transmiting or reflecting through skin, bone using photoelectric sensor by Power Capacity graphical method
Bone, blood etc. organize the decaying that can lead to light intensity to the absorption of light, since bone, blood etc. are constant to the absorbability of light, and
As heartbeat changes, tissue, endovascular blood volume can change, and the bigger absorption to light of blood volume is more, therefore
The light intensity signal measured according to photoelectric sensor can obtain the cyclically-varying of in-vivo tissue, vessel inner blood capacity, can
To calculate heart rate accordingly.In addition, sleep apnea event can cause the mutually strain of the information such as the eye electricity of patient, the oxygen content of blood
Change.
At present clinically for the diagnosis of sleep apnea syndrome mainly using hypnotic instrument is led, patient can be monitored more
Electrocardio, myoelectricity, brain electricity, eye electricity, chest and stomach wall movement, blood oxygen saturation, mouth and nose respiratory air flow and the sound of snoring etc..Using leading more
Hypnogram can accurately detect sleep apnea, be the gold standard of clinical diagnosis, but equipment is complicated, expensive,
Patient is asked to remain in a hospital under observation, monitoring data need professional to read, and need to place numerous electrodes and sensing on the patient whole body
Device can seriously affect patient at night sleep, while easy to fall off be easy to cause of sensor measures inaccuracy in sleep procedure.Therefore this
Kind mode is suitable for making a definite diagnosis suspected patient, is not particularly suited for ordinary user's use.
In addition, also there are many researchs to attempt to lead hypnotic instrument instead of complex and expensive by easy monitoring means more, but all
It is by being monitored to a certain physiological signal, since there are certain disturbing factor, single differentiations in actual application
Standard can influence its accuracy, its application is caused to be restricted.
