Description

Artificial intelligence deep learning method corrects the monitoring method for continuing blood glucose
Technical field
The invention belongs to glucose monitoring techniques field, in particular to a kind of artificial intelligence deep learning method, which corrects, continues blood The monitoring method of sugar.
Background technique
Diabetes, which have become, seriously threatens one of chronic disease of human health, according to the statistics of the World Health Organization, glycosuria Patient's cumulative year after year, the diabetic of countries in the world has reached as many as 200,000,000, and China is even more to become the high-incidence of diabetes Area, for China diabetic more than 100,000,000, diabetes morbidity is up to 10%, increases by 5,500,000 every year on average, increases daily 1.5 ten thousand, increases by 600 per hour, increase by 10 per minute, worse behind increasingly increased diabetic, Prediabetes are in there are also 2.64 hundred million people, blood glucose is also unsatisfactory for diabetes diagnostic criterion not within normal value, from glycosuria Disease is just poor one step away, if not being careful in one's diet and taking exercise, may making them, sb.'s illness took a turn for the worse and becomes diabetes patient.
Diabetes be by inherent cause, immunologic function disorder, microorganism infection and its toxin, free radical toxin, spirit because The various virulence factors of element etc. act on sugar, the protein, rouge that body leads to hypoinsulinism, insulin resistance etc. and causes A series of metabolic disorder syndromes such as fat, water and electrolyte, clinically using hyperglycemia as main feature, typical case may occur in which more The performance, i.e. " three-many-one-little " symptom such as urine, more drinks, more food, syntexis.If diabetic is without properly treating or treating mistake When being easiest to cause many complication, such as fundus hemorrhage, eye-blurred, have a weak heart, blood pressure injustice is hidden, hyperlipemia, trick Numb or picotement, shank take out crick contraction, the refractory conjunction of oedema, skin disease, wound, gum swelling bleeding, fatty liver etc..If dragged Prolong with the passing of time, fundus hemorrhage and peripheral nerve symptom can be easy to cause.Severe diabetes mellitus is easy to appear ketoacidosis, stupor, kidney The illnesss such as dirty syndrome, albuminuria, headstroke.
Method without eradicating diabetes at this stage, can only be adjusted by frequently monitoring blood glucose value the feed of patient with Medication.Blood sugar test can find the blood glucose value abnormal conditions (blood glucose value is high or low) of patient in time, some hyperglycemic patients are not It is abnormal that itself can be discovered, can only be found in time by blood sugar monitoring, to prevent ketosis acid, ketosis poisoning etc..Hypoglycemia can also be made It will lead to brain tissue blood supply insufficiency at great harm, such as hypoglycemia, it is possible to cause death.Patient needs dense according to blood glucose Degree is to adjust diet and drug.
The method of traditional blood sugar test includes following several method: the detection that phlebotomizes, quick blood sugar radiomete detection, Blood sugar test paper colorimetric detection etc..
The first, venous blood samples blood sugar test is to obtain blood with centrifuge separation blood after phlebotomizing using biochemical instruments Slurry, blood plasma monitor system measurement by generating hydrogen peroxide after reacting oxidizing glucose with glucose oxidase, with another The number of hydrogen peroxide, and obtain blood-sugar content, the usual detection time of this method is slow, and is difficult to accomplish at once after vein haemospasia It examines, and the longer blood glucose of blood samples storage time will be reduced due to glycolysis.
Second, quick blood sugar radiomete detection has many advantages, such as small in size, portable, easy to operate, quick detection, fastly What fast blood glucose meter measured is the blood glucose value of peripheral blood, and peripheral blood is arteriovenous mixing blood, and theoretically its blood glucose level compares venous blood Sugar is slightly higher, and especially postprandial blood sugar differs greatly.The advantages of fast blood glucose meter is simple and efficient, but its result is inevitably slightly missed Difference.
The third, blood sugar test paper colorimetric method blood sugar test: this method, which does not need detector, can measure blood sugar concentration, but its It is a kind of semidefinite weight testing method, test paper can only be used at 18-35 DEG C.The blood glucose meter of early stage glucose oxidase colorimetric method, Change color after test paper and reaction of blood, to the time after erase drop of blood and place into blood glucose meter blood glucose value is obtained by measurement chromatography. The above method requires needle needle-holding hand and refers to or venous blood, is detected with blood.Although some methods are being widely used, some is Among research, but whether be a kind of that method they will extract the blood of patient, be to belong to invasive detection, patient can be caused Do not accommodate increase infection chance, it is also necessary to expensive consumables, so not being ideal detection method.
In order to solve inconvenience brought by invasive inspection and pain, noninvasive dynamics monitoring has become competing both at home and abroad in recent years The mutually hot spot of research and development, the detection of Woundless blood sugar include near infrared spectroscopy, mid-infrared light spectrometry, metabolism thermal method etc., these methods All is mostly that blood sugar concentration is determined using spectrum analysis, some can also the parameters such as combination temperature, humidity analyzed, but due to Human body environment is complicated, and everyone body difference, and existing blood glucose meter precision is not generally high, therefore clinical and market is all It is not widely popularized.The general big rise and fall of the blood glucose value of diabetes patient, invasive monitoring and Woundless blood sugar values all at present Blood glucose value can only be read at a small number of time points, the blood glucose meter that can continuously monitor becomes the demand of numerous diabetics, also takes Certain achievement was obtained, such as someone has developed the blood glucose meter of sustainable monitoring, this is a kind of minimally invasive blood glucose meter, and probe is implanted into skin Under, the blood glucose fluctuation in subcutaneous space interstitial fluid can be continuously recorded, can be completed over time to blood glucose trend Tracking, while inflammation can be also generated, so that monitoring signals is affected, but continous way blood sugar monitoring is the hair appointed be so from now on Direction is opened up, research and development temperature is high, and technology is left to be desired.
Existing glucose monitoring techniques are mostly finger tip blood drawing monitoring, due to finger tip blood drawing skin can be generated certain wound and Pain, patient are often unwilling often to draw blood, and can generate conflict psychology, this is just likely to the best period of delay treatment, Cause serious consequence, and this method can only spot measurement, cannot reflect the trend of change of blood sugar, be unfavorable for the prison of the state of an illness Control and treatment, some non-invasive blood sugar instruments occurred currently on the market equally have this limitation, and the disadvantage of non-invasive blood sugar instrument maximum Be to measure it is inaccurate, it is most of by infrared this is because non-invasive blood sugar instrument is not direct detection human blood glucose concentration The variation of tissue fluid is detected, blood glucose value then is calculated using algorithm, but since human internal environment is complicated, and person to person Between body it is also variant, while being influenced again by external environment, therefore although noninvasive dynamics monitoring avoids make patient Body is by wound, however but there is very big errors, also just can not really react glucose situation.Sustainable blood glucose meter energy The blood glucose fluctuation of enough preferable reflection diabetics, it is to be implanted by probe subcutaneously, records the blood glucose in subcutaneous space interstitial fluid Fluctuation, in the blood glucose value that a few days ago can accurately measure patient of implantation, but with the growth of probe Implantation Time, meeting Inflammatory reaction is induced, the exact value of measurement is influenced.
With machine learning, the rise of artificial intelligence, artificial intelligence technology is used for diabetes glucose value by many scholars The combination of detection, especially Woundless blood sugar monitoring and machine learning.Since machine learning needs biggish data collection capacity ability Preferable learning effect is obtained, and data collected there must be certain accuracy, but often due to non-invasive blood sugar instrument It can only just be capable of measuring at some time point, be unable to continuous acquisition data, this just brings biggish workload to the acquisition of data, number It is less not accurate enough plus data according to measuring, therefore there is no good learning effects.In addition, in addition, such method can not Achieve the effect that personalization, it, can be from many diabetics when acquiring data in order to make up the inadequate defect of above-mentioned data volume Trained data are obtained with it, are then gone to detect other patients again with this result, it will be clear that since interpersonal body is poor The effect of different reason, detection is not very good, moreover, such method obviously considerably increases workload, therefore cannot be obtained To extensive use.
Therefore, research and develop it is a kind of for diabetic can provide accurately and reliably blood glucose real time data, preferably to manage The monitoring method for managing the lasting blood glucose of artificial intelligence deep learning method correction of own bodies situation is extremely urgent.
