Description
Technical field
The present invention relates to biomedical engineering and pharmaceutical information technical field, specifically a kind of data flow method based on left guan synchronous acquisition pulse wave and blood pressure.
Background technology
The feeling the pulse of the traditional Chinese medical science is from ancient times diagnosed a disease, the Han dynasty Zhang Zhongjing from all over examine be improved to " solely getting the area on the wrist over the radial artery where the pulse is felt for diagnosis " and " three body parts and nine pulse-taking sites " method after, the successive dynasties all the someone objectify, digitized exploration.Digitizing technique up to the pulse-taking seventies of 20th century has just had further research and development, has realized modern " suspension is felt the pulse " that combine with " blood circulation dynamics arteries and veins figure detects and pulse instrument ".But clearly should not be standardized as " left guan three marquis " method, the method for yet unresolved synchronous digital collection online.So that the application of above-mentioned technology and instrument all can only be operated by the professional, all be to gather body surface left radial artery pulse information, coupling left brachial artery blood pressure is finished.In order to guarantee to measure accuracy of blood pressure, still continue to use traditional mercurial sphygmomanometer and measure blood pressure.Though asynchronous equal error is arranged like this, and such error often is left in the basket also, and can not realizes automatization, digitized online carrying out date processing and analysis.
Electric sphygmomanometer has become the main tool that family's blood pressure detects through years of development.Modal on the domestic market is the Omron electric sphygmomanometer, and its product is also progressively ripe, and has developed the more complete different series of kind.Current electric sphygmomanometer is because of simple to operate, friendly interface, and individual self contrast can illustrate the variation of blood pressure, day by day is subjected to domestic consumer's approval.But its accuracy is owing to oscillographic method principle and chip (DSC) produce error to the limitation of pressure and current conversion, uses at random and hypertension or hypotensive critical patient used to be restricted.Over past ten years, breakthrough is arranged along with electric sphygmomanometer is technical, product is ripe and progressively enlarge popularization, and the hospital that has also has been applied to health care.
The traditional Chinese medical science is deep to the feeling the pulse of one of " four diagnostic methods " understanding of diagnosing a disease, and its method is exactly the palpation (being called " pulse-taking ") by the area on the wrist over the radial artery where the pulse is felt for diagnosis, seeks and visits the whether peculiar signs of the traditional Chinese medical science such as imbalance of YIN and YANG, deficiency and excess cold and heat of human body.With the examination patient disease and the state of an illness roughly.Doctor in long-term clinical practice knows " between pulse-taking inspection and the heart change exist work confidential relation ", and state identification, judgement and diseases prevention and treatment that physiology, pathology and the pharmacology that has hemodynamics to change changed are all significant.The essence of pulse wave spectrum " marquis's QI and blood " is the hemodynamic state of monitoring human integral body, and the value of its application usually surpasses methods such as electrocardiogram.Medical three referred to pulse-takings during we learnt to realize in the practice of the traditional Chinese medical science, in fact had with middle finger pressurization (inflating as inflator pump) to measure the effect of blood pressure, just were difficult to accurately and digitized is obtained blood pressure values.So pulse-taking should be to gather the measurement that pulse condition adds blood pressure.It is not all right only to measure blood pressure, blood pressure is all three people of 150/80mmHg, may be respectively hypertension, rheumatic heart disease, coronary heart disease, only add the digital assay of pulse condition (trace and be " arteries and veins figure " or pulse wave), just can have been distinguished, a same hypertensive patient is if add arteries and veins figure or pulse wave, the patient that can also test and assess has acardia (target organ) to get involved and situation such as Peripheral resistance, carries out the individuation determination of treatment based on pathogenesis obtained through differentiation of symptoms and signs.
Now, biomedical engineering circle hankers after developing the Chinese medicine pulse instrument, because still in the method for continuing to use " three ones nine marquis ", the generation operation is disturbed in pulse condition extraction processing unavoidably, the synchronous measuring blood pressure of feasible combination is used and carried out date processing and also is difficult to realize.The traditional Chinese medical science is the darkest to pulse-taking understanding, its method is exactly by the diagnosis to pulse condition, and diagnose a disease people's roughly disease of inspection is sought and visited whether distinctive signs such as imbalance of YIN and YANG, deficiency and excess cold and heat of human body, carry out carefully partly analysing but suffer from shortage quantification means, also can't circulate mutually with modern western medical science.There is following defective in existing pulse condition technology: 1. learn feature not in full conformity with the physiology of human body, pathology and special physiological, be open to misunderstanding, mistaken diagnosis and misleading; 2. accuracy, reliability can't reach the requirement that synchronous online inspection is examined; 3. can't detect drug effect, curative effect; 4. can't satisfy the knowledge structure of different user; 5. can't provide intelligible health care consultation and determination of treatment based on pathogenesis obtained through differentiation of symptoms and signs to various objects.So that existing pulse-taking technology can't adapt to user's multiformity requirement in application facet.

If 3. the pulse wave waveform is defective, should take out pulse transducer and lay again and inflate, qualified until waveform.
(3), inflation pressurization
When 1. slowly being inflated to 2/3～3/4 value of diastolic pressure, pulse wave preferably can occur, see that the relatively stable back of waveform gathered pulse wave 10 seconds, and enter A/D automatically and be converted to Data (1);
2. continue to be inflated to pulse wave b point (∨ shape cusp) and cut or see short flat horizontal line, the blowing pressure (CP value) of this moment is recorded as PDP1;
3. continue pressurization and be inflated to pulse wave peak (C point and whole waveform just disappear), the blowing pressure this moment (CP value) is recorded as PSP1.
(4), venting
Visible pulse wave progressively occurs in slowly exitting, and reappears until complete pulse wave.
(5), defuelling pressurization
Same step (three)～(four) comprise and gathered pulse wave 10 seconds, and enter A/D automatically and be converted to Data (2), and b point CP value record is PDP2, and c point CP value record is PSP2.
(6), three inflation pressurizations
Same step (three)～(four) comprise and gathered pulse wave 10 seconds, and waveform shows and enters A/D automatically changes Data (3), and b point CP value record is PDP3, and c point CP value record is PSP3.
Consult accompanying drawing 2, a point is the atrial systole starting point among the arteries and veins figure; B point (seeing ∨ shape cusp) is aortic valve opening point, the i.e. intrinsic pressure minimum point of left ventricular end diastolic tremulous pulse (PDP); The c point is the intrinsic pressure peak of aorta, i.e. the intrinsic pressure peak of left ventricle shrinkage period artery (PSP); The c point is aorta maximal pressure force; The d point is the aorta elasticity oscillation point; The e point stops to penetrate the blood point for left ventricle; e
