Technical field
The present invention relates to sensing device, more particularly, to the portable noninvasive continuous blood pressure monitoring sensing device of one kind.
Background technology
Modern High-Tech makes rapid progress, the high speed development of internet, and we have welcome the big number of healthy living, Medicare
According to the epoch.Country is also proposed the propulsion plan of fitness-for-all medical treatment in good time, and the development of healthy old-age care is supported energetically.The whole people
The development of medical treatment, will promote the high effective integration of medical resource, promote the change of medical model, reduce huge medical expense and bear
Load.And in this main trend, due to the demand driving of medical big data, light mobile data terminal harvester（Than
Such as Wearable basic physiological parameter real-time acquisition device）Research and development turn into focus.Relative to the maturation of network technology, it may be said that this
Class physiological data terminal lacks, it has also become the severe bottleneck of big data medical treatment.Although the commercialization health of existing profile fashion
Bracelet, can record the daily exercise situation of people, and the indirect sleep quality for inferring people of action monitoring for passing through hand.Also deposit
In the medical Holter systems of the continuous ECG monitorings of specialty（Dynamic ecg monitoring system）.It should say, so far, have no business
Industry, wearing comfort is good, do not influence people's daily routines, suitable for the long-term continuous real-time physiological parameter monitoring of human body
Mobile data terminal.
With the high speed development of society, the dietary structure of people also quietly changes, " three high " phenomenon in modern society
Protrude very much, had a strong impact on daily life and physical and mental health.The development of society, life and work tempo increase is also given
The pressure that large quantities of working clans bring also is increased rapidly, and many people are in sub-health state.Meanwhile, China quickly steps into aging society
Meeting, the aftereffect of family planning policy result in more and more " empty nest " family and be formed.In view of above trend, research and development are suitable to wear
The mobile data terminal for the basic physiological parameter current events monitoring worn, is modern technologies and the demand of social development, and is developed properly
Intelligent sensing device is that it is crucial.
Blood pressure can reflect the function status of human heart and blood vessel as one of human body basic physiology parameter, be to face
The important evidence diagnosed the illness on bed, observe therapeutic effect, carried out Index for diagnosis.Human blood-pressure is with physiological period, individual human feelings
Thread, the external world and inherence various stimulations and produce change, with obvious fluctuation.
Because blood pressure parameter is influenceed by factors such as health, environmental condition and the physiology rhythms, single measurement or
There is bigger difference in the result discontinuously measured, and method for continuous measuring can measure blood pressure in each cardiac cycle, in clinical and doctor
Learning has prior meaning in research.The change for changing the sympathetic nerve activity parallel with normally sleeping-waking up the cycle of blood pressure
It is relevant.For sudden cardiovascular and cerebrovascular disease, Morning Blood Pressure has very important significance.Pathologic, physiologic and epidemiology
Research shows the occurrence probability increase in the morning of SCD, acute myocardial infarction AMI, cerebrovascular disease and cerebral apoplexy.Pass through continuous blood
Pressure monitoring, this symptom can be found in time, be patient and doctor predicts the development of the state of an illness and wins the quality time.Continuous blood pressure is surveyed
Amount can provide corresponding blood pressure transition information, so that deduction and sleep quality for sleep info, by stages and sleep-disorder
Diagnosis provide foundation.
Stethoscopy：Stethoscopy (Auscultatory Method), also known as Korotkoff's Sound method (Korotkoff-Sound
Method), it is one of most non-invasive detection method of clinical practice, its principle is to utilize to inflate cuff compressing arteries,
With the decline of cuff pressure, arteries in complete blocking-gradually open-standard-sized sheet change procedure, by distinguish artery blood flow by
Cross streaming voice and corresponding pressure spot to determine systolic pressure and diastolic pressure during resistance.There is inflation-deflation course, so not
Human body artery blood pressure can continuously be measured.
Oscillographic method：Oscillographic method (Oscillometric method), also referred to as vibration measuring method or vibratory drilling method, are clinically each
The widely used blood pressure measurement technology of class patient monitor, electronic sphygmomanometer.Blood pressure cuff is entangled on patient's arm, what cuff was picked out
Rubber tube is connected on the air pump of non-invasive blood pressure (NIBP) circuit board.Air pump to cuff inflation, make arm arteries close this
When be blocked because of blood flow, the pressure sensor on NIBP plates is only capable of detecting the cuff pressure of static state, and does not detect artery blood flow
Pulse (beating), at this moment inflation stops, vent valve starts progressively to deflate under control circuit function, and cuff pressure is gradually reduced,
The arteries of closure gradually opens, and begins with blood flow and flows through.Then pressure sensor, which is able to detect that, is superimposed upon in cuff pressure
Pulsatile arterial blood pressure.
Angiosthenia method（Arterial Tonometry）：It is to be applied by being pointed to the body surface artery part near bone
External pressure, it is in flat form to make it.Now artery acts on the power on the surface approximate with the pressure in artery into rigid surface state
It is proportional.Therefore can be by measuring the pressure transducer for being placed in radial artery position the pressure on the surface, thus obtain
To the arterial pressure waveform often clapped, and detect the maximum and minimum signal of arteriopalmus to obtain pressure value.Angiosthenia method can
Continuously to measure arterial pressure, but this method is high to sensor positioning requirements, must be long by angiosthenia on bone during installation
During time measurement, keep sensor measurement position more difficult.Meanwhile, the need for the application of external pressure and adjusting apparatus, general
In the case of the method be also difficult to turn into Worn type equipment.The difficult problem of positioning, also limit its application.
Volume-compensation method：Also known as vascular unloading technique, is in artery by preset reference pressure value and goes load condition,
Changed simultaneously using servo-drive system compensation arterial volume caused by the change of artery internal pressure, make arterial volume maintain to go load to move
Arteries and veins volume, now oversleeve internal pressure is equal to artery internal pressure, therefore can measure arterial pressure indirectly by measuring oversleeve internal pressure.This method
Implementation process need a pressure servomechanism, can adjust impressed pressure in real time according to fluctuation of blood pressure is in vascular wall
Constant volume state.Volume-compensation method is continuous BP measurement method more ripe at present.Measurement apparatus is complicated, to quilt when using
Examination person makes troubles, and is also not suitable for using in the observation of long-time continuous blood pressure.
Plethysmography：In heart beat cycles, flowed through in the arteriole, capillary and venule in peripheral vascular
Blood accordingly in pulsating nature change.Volumetric blood is maximum when the heart contracts, and volume is minimum in diastole.Blood
This pulsating nature change of volume, can typically be obtained by photoelectricity volume sensor, contain volume pulse blood in the waveform of gained
Information.Therefore diastolic pressure and systolic pressure, this method can be obtained by volume pulse blood information and the relation of blood pressure signal
It is referred to as photoplethysmography.Generally measured in finger tip, because finger tip blood flow experiences area greatly, to test position requirement
It is less strict；The adaptability of signal, stability and repeatability are superior.But the mechanism for volume pulse blood signal is special with information
Relation does not have abundant announcement between levying, and precision is difficult to ensure that.
Pulse velocity of wave determination method：According to pulse wave along between artery propagation rate and arterial pressure have positively related feature
Propose, arterial pressure value is extrapolated indirectly by measuring pulse velocity of wave.
In summary, stethoscopy, oscillographic method and volume-compensation method are only suitable for batch (-type) measurement；Plethysmography, pulse wave
Fast determination method can be used for continuous BP measurement, and the former precision is difficult to ensure that, the latter needs multimetering, is unfavorable for wrist blood pressure
Portable, the design for aesthetic of meter.
