Description

Dynamic cardiovascular activity monitoring method and the system using this method

Technical field

Supervised the present invention relates to a kind of dynamic cardiovascular activity monitoring method and using the Wearable cardiovascular activity of this method Examining system, more particularly to a kind of method for changing calculation, operation and data processing method according to the signal quality of physiological signal And system.

Background technology

Modern increasingly focuses on the health of oneself, it is especially cardiovascular in terms of health, and with cardiovascular health most phase What is closed is exactly heart, and in order to understand the situation of heart, it is inspection the most traditional that detailed Electrocardioscopy is carried out in hospital Mode, it can observe most heart disease by way of inspecting ecg wave form, for example, cardiac arrhythmia, cardiac muscle stalk Plug, ventricular hypertrophy etc., in addition it is distinguishable go out heart disease kenel, for example, ventricle type or atrium type cardiac arrhythmia or left ventricle Or right ventricular hypertrophy etc., simply, such mode is not only limited to time, place, also more bothers for patients, in addition, Because some heart diseases, for example, cardiac arrhythmia in being detected instantly for breaking-out, it is necessary to can just obtain useful electrocardiogram, Therefore, there is its limitation on the contrary.

And in order to obtain electrocardiogram when occurring cardiac arrhythmia, the one of which that doctor can typically allow patient to carry out is examined Survey is exercise electrocardiogram, it is, can increase and easily induce the concept of cardiac arrhythmia using cardiac load when moving, and allows trouble Person is directly moved in hospital, for example, in running on treadmill, and with time detecting electrocardiogram, it is desirable to the heart can be caught The moment for work of not haircuting is restrained, in addition, doctor also often allows patient to carry out wearing Huo Teshi electrocardiographs (Holter) at least 24 hours Detection, it would be desirable to the cardiac arrhythmia symptom that may occur at any time is caught in the way of measuring for a long time.

But these modes have its inconvenience for user, still, for example, the Huo Teshi electrocardiographs of 24 hours Though can be full-time record electrocardiogram, result can not be learnt in real time, it is necessary to after whole measurement terminates, returning to hospital will After data recorded in device are downloaded and analyzed, it can just know whether and recorded symptom, so the situation usually having is, etc. Find cardiac arrhythmia disease do not occur in the wearing record of 24 hours or more time when can watch analysis result to patient Shape, is detected equal to the time that wastes and energy, moreover, such Electrocardiography, it is necessary to pass through health care professional's Assistance could be set, and need to paste electrode with for a long time, easily produce skin uncomfortable；Furthermore, prolonged detection will Substantial amounts of data are produced, either storage device is interior or is uploaded to high in the clouds, substantial amounts of storage area can be all consumed, as thing Post analysis and the progress understood, then either traditionally manually carry out analysis deciphering by medical personnel, or uses high in the clouds now The mode of calculating, is all to need to expend a large amount of computing resources to complete.

In addition, the detection of exercise electrocardiogram is similarly very possible because there is not cardiac arrhythmia during moving within the hospital Symptom and make a futile effort.

Occur that the ECG tester that can be used with oneself in recent years, its allow user can usually whenever necessary, For example, when thinking that heart is uncomfortable, the detection of short time is carried out at any time, for example, 30 seconds to several minutes, to record electrocardiogram, And doctor can be diagnosed.Simply it has also been limited, for example, due to being measured in the device using such a kenel When, body movement has a great impact to the whether good of electro-cardio signal, so, user must be examined under static state Survey could obtain useful electrocardiogram, and because the record time is very short, therefore be only suitable for being detected once in a while, it is impossible to for a long time and even The information of related cardiac is provided continuously.

Another selection that can continuously obtain heart information is heart rate monitoring unit, and it is drawn by detecting pulse wave change Heart rate, the advantage of such device is to be adapted to wear for a long time, because it generally uses optical sensor (optical Sensor), only need to contact skin can measure, and install easy, also do not result in skin uncomfortable.

Now, general common heart rate monitoring unit is Wearable exercise heart rate monitoring device, and it generally utilizes wrist strap, arm Band or pectoral girdle and wear with, user can be allowed to wear during movement, the heart rate that wearer is provided under mobile situation becomes Change, to help user to grasp the exercise intensity of itself, simply, also due to such application target, limits the offer of its information Content.First, in order to overcome the measuring environment that mobile possibility is high, such device, which normally only has, provides average heart rate Function, for example, the average heart rate that the heart rate before and after constantly average in 10 seconds is drawn, and can not real time reaction user the heart Rate, be additionally, since needs could provide numerical value after average, therefore the problem of also there is display delay always, it is, being User is not in motion or mobile status, still exist the problem of above-mentioned, therefore, such device is obviously suitable only in fortune Dynamic period uses, if to be used in daily life continuously obtain heart rate information, to observe heart state for a long time, is then not suitable for.

From the foregoing, in the case of being intended to obtain cardiovascular relevant information, according to Holter to obtain continuous electrocardio Figure, must just face and paste the inconvenient and uncomfortable of electrode for a long time, for example, can not voluntarily install, in fact it could happen that skin is uncomfortable, But the electrocardiogram of short time obtains but is necessarily limited to higher operating environment limitation, for example, body movement is clear to signal The influence of degree is big, need to be in measurement under rest configuration, it is impossible to obtained for long-term signal；If in addition, wanting to move the heart using Wearable Rate monitoring device monitors the heart situation of itself on ordinary days, then can only obtain limited information, for example, only average heart rate, it is impossible to The enough information further to analyze is obtained, for example, heart rate in real time.

In addition, one of the problem of long-time physiology monitoring is most commonly encountered is exactly that electric quantity consumption is excessive, for example, it is desired at least 24 The continuous ECG detected more than hour, or the larger optical sensor detecting of continuous illumination, electric quantity consumption is needed, and work as When electrical demand is big, the battery volume of required outfit also becomes big with respect to the need for, will be the increase of burden for user.

Therefore, certain a kind of Wearable cardiovascular activity monitoring device that can solve the problem that disadvantages mentioned above in need, it is possible to provide User's cardiovascular information, and user can be allowed under convenient, comfortable use situation, the cardiovascular feelings of long-term monitoring itself Shape.

Embodiment

The cardiovascular activity of itself is monitored in daily life in order to be able to provide user with most convenient and effective manner, According to the dynamic cardiovascular activity monitoring device of the Wearable of the present invention, use while having setting at least two expression formulas Meter, to allow the device with being worn on to be suitable for the difference activity of daily life, and has selectivity and provides in most suitable information Hold.

Therefore, in the present invention, the dynamic cardiovascular activity monitoring device of the Wearable is except being embodied as wearing in using With person, obtain and be relevant to outside the physiological signal of cardiovascular activity by an at least physiology sensing element, still obtaining life Manage after signal, judge to draw the signal quality of the physiological signal, and decided whether to physiological signal according to the signal quality Perform calculating, and the calculation formula to be performed why, and after being calculated using selected calculation formula, then pass through a letter Breath provides interface and provides user the corresponding information content.Therefore, it is cardiovascular living according to the Wearable of present invention dynamic At least two calculation formulas, one first calculation formula and one second calculation formula are preloaded in the processor of dynamic monitoring device, to adapt to Different signal quality and optionally perform.

Here, the reason for present invention is using signal Quality estimation information is, it is desirable to correct cardiovascular letter can be provided Cease to user.General existing heart rate monitoring unit is not in the case of signal quality is considered, it is easy to because be with quality not Good signal causes to be supplied to the cardiovascular information of user incorrect as analysis foundation, for example, the heart rate information of mistake, The puzzlement of user is caused on the contrary, therefore, if can first understand the height of signal quality, so that it may avoid such situation, also allowing makes User can obtain real-time and correct cardiovascular information.

The judgment mode of the signal quality is, while physiological signal is obtained, and can also obtain signal quality correlation letter Breath, and when the signal quality related information meets a preparatory condition, for example, stability, definition, signal noise ratio (S/N Than Signal to noise ratio) etc. when being higher than a preset value, represent that signal quality is high, and when signal quality correlation letter When breath is not inconsistent the preparatory condition, for example, when stability, definition, S/N ratio etc. is less than a preset value, then it represents that signal quality It is low；As for calculation formula selection be then to be determined according to the judged result of signal quality, this first calculate formula in signal quality not Performed when meeting the preparatory condition, and the second calculation formula is performed when signal quality meets the preparatory condition.Here, not by Limit ground is, the preparatory condition can be embodied as multiple, and the thinner of signal quality classification is more beneficial for producing more accurate physiology Information, moreover, also being embodied as multiple calculation formulas, and when being embodied as different preparatory conditions, therefrom selects suitable calculation Formula is calculated, in addition, different selections can also be had by representing the mode of signal quality, for example, using a performance figure (quality index) is to represent, or can also be represented by credit rating (quality level), does not limit.

In addition, further, when determining the signal quality, it can also judge acquired signal if appropriate for performing meter Calculate, for example, the movement of user's body is excessively fierce and causes signal quality too poor, now, the processor just may be selected not perform It is any to calculate, and recover whne signal quality to when being enough to perform calculation formula, just perform the selection of calculation formula.

The factor of influence signal quality has a lot, and the influence that different factors is produced to signal is also different, for example, physiology The artificial disturbance source (artifacts) of signal and/or noise (noises), the stability that physiology sensing element is set, device sheet The interference that body is brought, the interference that surrounding environment is brought etc. is all possible factor, wherein, the physiological signal of user occurs Artificial disturbance source and/or noise are very common situations, especially when user moves or moved, but, due to basis The device original idea of the present invention is that allow user to be worn on persistently is detected with it, and therefore, body movement occurs in user The situation for being nature and being expected；In addition, physiology sensing element occurs setting incomplete situation, for example, connecing between skin Touch not enough or be not sufficiently stable, be also one of very common situation, but as long as paying special attention to just be avoided by；In addition, from outer The interference in portion, for example, the swing of the connecting line of device in itself or the Electromagnetic Interference etc. of external environment all may be acquired Physiological signal bring noise, therefore be also all the factor for needing to consider, therefore, the factor of influence signal quality has many can Can, without certain limitation.

Moreover, it is preferred that the signal quality can also be made in addition to as determining to use the basis of any algorithm Be shown to user for another information, for example, when user be in it is static when, performance figure/grade is but shown as It is low, then user can because of it is such prompting and know be probably because physiology sensing element set completely caused by quality It is not good, and then be adjusted in real time；Or, the signal quality not may be used as operation of the person during installation or measurement yet and refer to Draw, for example, when with user mounts a device onto, can judge whether correctly to have installed by signal quality information, or, When it is in need measure manually when, can also learn operation instantly whether just by the signal quality information provided in real time Really, therefore, no matter which kind of situation, all will can reduce because it is improper operation and produce error.

Furthermore, also have many possibility about the selection of the signal quality related information.For example, in a preferred embodiment In, can be directly by analyzing as the physiological signal acquired by the physiology sensing element, for example, using frequency analysis The mode of (Frequency Domain Analysis), such as Fourier transform (FFT, Fast Fourier Transform) and Decide whether containing artificial disturbance source (artifact) and/or noise (Noises), or, by the volume or pressure of analyzing blood vessel Power changes or analyzed electrocardiogram etc., and draws the body movement situation of wearer, to be used as the signal quality related information； In an another preferred embodiment, the body movement situation of wearer can be detected by setting up an action sensing element, and is made For the signal quality related information, for example, can have an activity pattern preparatory condition, for example, when activity intensity and/or unit Between activity etc., device/physiology sensing element activity pattern caused by action sensing element detects body action is not When meeting the preparatory condition, the signal quality of physiological signal that will be now acquired is considered as low, another aspect, if meeting, Be considered as signal quality high, and be unrestrictedly, preparatory condition can be embodied as it is multiple, also, because body movement may only be short It is temporary time, therefore may be alternatively provided as, above-mentioned in the unit interval not meet situation to be just considered as signal quality more than certain number of times low, To be conducive to producing more accurate physiologic information；In another embodiment, can by physiology sensing element and skin it Between, set up a contact sensing element and detect the setting situation of physiology sensing element, for example, whether contact between the two is enough, This can equally be used as the signal quality related information, and also by way of setting preparatory condition judged result can be made completeer It is kind；In an another embodiment, then quality related information can be obtained by way of electrode is set, for example, myoelectricity news can be detected Number (EMG) and the tensity for learning muscle, or Skin Resistance (impedance) or skin conductivity degree can be detected and learn skin and connect Tactile situation etc., then different preparatory conditions are equipped with, just allow the judgement of signal quality more effective.Therefore, according to being taken Signal difference, the signal quality related information can also be varied from, institute according to preparatory condition can also adjust, therefore It is unrestricted, also, it is noted that above-mentioned citing be not limited to be used alone, can also merge and use, for example, can be simultaneously Action sensing element and pressure sensing element are set, to allow the judgement of signal quality to be easier, do not limited completely.Here, should Action sensing element can be, for example, action sensor, accelerometer etc. are typically commonly used in the mobile sensor of detecting, In addition, the contact sensing element can also have many selections, for example, pressure sensor, touch switch, touch sensing etc., because This is not limited.

In addition, the physiologic information content provided, in addition to being determined according to signal quality, used calculation formula, also phase On used physiology sensing element.Include in general, can obtain and be relevant to the physiology sensing element of cardiovascular information, but It is not limited to, light volume change (PPG, photoplethysmography) sensor, pressure sensor, and electrocardioelectrode, lift For example, PPG sensors and pressure sensor can obtain heart rate relevant information, wherein, PPG sensors are to utilize the change of light volume Principle and the sensor for obtaining optical signal, it can learn heart rate sequence by the consecutive variations of detecting pulse, and pressure sensing Device be then can artery produced by by detecting heartbeat or body (such as thoracic cavity) vibration and obtain heart rate information, for example, logical Cross and be arranged at pulse, in addition, PPG sensors can also obtain the information of related blood oxygen, for example, when with infrared ray (Infrared) blood oxygen concentration (SPO can and during red light (Red) two kinds of light sources, be obtained₂), and electrocardioelectrode can then be obtained Electrocardiogram, to provide the various information of related cardiac activity, and (comes from pulse wave it is possible to further the heart rate information obtained Signal and/or electrocardiogram person) based on, and provide relevant HRV (Heart Rate Variability, heartbeat aberration rate) and from The information such as nervous activity situation is restrained, also therefore, when used physiology sensing element is different, the calculation formula being applicable is also It is different.

Here, it is noted that because the apparatus according to the invention is implemented as being worn on the form with user, because This, as long as used physiology sensing element stable by the behavior of dressing can be set, is not limited to specific shape Formula.

Next i.e. how narration in the concept of the present invention, provides different calculation formulas according to different signal quality, To provide user various corresponding physiological informations.Here, need to illustrate in advance, by either captured physiological signal The selection of the behavior or the calculation formula used of species, user during physiology detection apparatus is dressed, all can be because of various shapes Condition and it is different, therefore, in ensuing narration, to avoid confusion, the calculation formula that is used when signal quality is low will It is referred to as the first calculation formula, the physiologic information provided is referred to as the first physiologic information, and used when signal quality is high Calculation formula is then referred to as the second calculation formula, and the physiologic information provided is then referred to as the second physiologic information.

Referring to Fig. 1, it is according to the signal process chart of a preferred embodiment of the present invention, its with PPG sensors and/ Or based on the heart rate information that can obtain of electrocardioelectrode.After physiological signal is obtained, when determining signal quality, news can be first determined Whether number quality is not enough to perform calculating, for example, one of which situation is, signal quality is drawn according to signal quality related information Bad is due to that sensor/electrode is fallen off or loose contact, for example, it was discovered that signal interrupts, loses physiological characteristic etc., herein Under situation, calculating/analysis will not be performed, and provides interface by the information and reminds this phenomenon of user, on the other hand, also can Whether improve, and restart calculating/analysis when recovering if continuing the setting situation of detection sensor/electrode.

Another situation condition is, according to signal quality related information draw signal quality it is bad be due to user's movement institute Cause, for example, action sensing element detects a large amount of, prolonged movement, in this case, if it is mobile have resulted in physiological signal without Method is analyzed, then without calculating/analysis, and user notify can not to be calculated/analyze greatly very much because mobile, now, compared with Be goodly, it is further provided the information of user's relevant action sensing element, for example, activity intensity and/or activity, using as The reference of user, and similarly, in this case, the also mobile situation of sustainable monitoring user, and extensive in signal quality When multiple, for example, when movement slows down/stopped, restarting calculating/analysis；On the other hand, if noise caused by mobile and/or Artificial disturbance source etc. can be removed by configuration processor, and the physiological signal after removed program still has physiological significance, then exists Under this situation, it is preferred that in performing after removal program, user, example are supplied in the way of the average data of a period of time Such as, average heart rate, wherein, obtaining the method for average data has multiple choices, for example, using the mode of frequency-domain analysis, or, Rolling average (moving average) can also be used, or removes the mode such as average (trimmed mean) end to end and obtains Average data, and allow user still to will appreciate that the substantially variation tendency of physiological status, or, alternatively, also can be in signal quality When bad, acquired physiological signal is handled using the mode of reduced sampling (down sampling), except reaching data compression Purpose outside, computing resource and power consumption can be also saved, therefore equally feasible method, in addition, it is preferred that flat providing While equal data, signal performance figure is also provided, allows user to be also aware that the physiological signal matter for calculating this average data according to this Why is amount.Furthermore, when carrying out signal processing, it is possible to use common DSP program (Digital Signal Processing), for example, Laplce (Laplace) changes, Fourier (Fourier) conversion, and Hilbert (Hilbert) change, therefore Z conversions etc., do not limit.

Here, it should be noted that as described above, because the first calculation formula that signal quality is not good and uses can be according to reality The difference of border situation and have different selections, can be above-mentioned single or any combination, be not only restricted to specific processing mode.

Therefore, by above-mentioned mode, even under the not good situation of signal quality, also allowing for user and obtaining correct And in real time physiologic information, and understand device actual operation situation why, moreover, further, it is important that ground is, such Operating mode also can reach power saving, save storage area, reduce the benefit such as computing resource afterwards, for example, high in the clouds storage area with And cloud computing resource.

Further, by the judgement of signal quality, and it can reach the effect of power saving.Due to the master according to apparatus of the present invention Being of syllabus carries out continuous physiology monitoring, for example, 8 hours, the continuous monitoring of 24 hours, therefore, one of them is quite crucial Emphasis be whether electric power is enough to provide prolonged running, and because in most cases, the volume of Wearable device is more It is decided by the size of battery, therefore, if the consumption of electric power can be reduced, is also beneficial to reduce burden during user's object wearing device.

Accordingly, by above-mentioned mode, when the quality for judging current physiology signal is not enough to be analyzed, so that it may enter One step effect for reaching power saving by reduction, the electric quantity consumption of stopping physiology sensing element, for example, in an embodiment In, what the luminous intensities of PPG sensors was directly affected is the amplitude size of acquired physiological signal, therefore generally can be by adding Strong luminous intensity and overcome the interference caused by environment light source, but when cause signal quality it is not good be other reasonses when, for example, Sensor, which is set, there are the situations such as release, body movement is excessive, then is easily detected by changing luminous intensity and being improved, because This, in this case, before signal quality can not obtain improvement, so that it may reduce luminous intensity, even stop luminous and reach drop Low battery consume, wherein, according to be reduce luminous intensity mode, can save power consumption while also persistently supervise Survey whether signal quality has improved, recover luminous intensity again after improving, and in the case of stopping luminous, then can be by regular Ground starts PPG sensors and monitors whether signal quality has improved, it is to be restored after again restart the detecting of physiology sensing element Action, moreover, the pause of PPG sensors is luminous to represent that the sampling of signal has stopped, therefore can also reduce data volume and required storage Space；Furthermore, in a further preferred embodiment, also can be when signal quality be low, by the sampling for changing physiology sensing element The mode of rate, for example, the sampling rate of reduction electro-cardio signal and/or pulse wave signal, and reach the effect of power saving, it is however generally that, it is high Sampling rate is conducive to obtaining accurately analysis result, but when signal quality is not good, then need not too high sampling rate, therefore can lead to The mode for crossing reduction sampling rate only obtains rough heart rate information and/or is used as the judgement of signal quality, is disappeared with reducing electric power Consumption, also, can also reduce data volume and required storage area and save calculating time and resource, it is the side of suitable tool efficiency Formula.

Furthermore, also having is advantageously, the storage action carried out for ex-post analysis, can also find that signal quality is not enough (no matter whether physiology sensing element changes luminous intensity, stops sampling or reduction sampling rate) is temporarily stopped during being analyzed Only, for example, it was discovered that when sensor/electrode has come off, can stop-record signal, and this phenomenon is marked, consequently, it is possible to can not only save Province storage area, is greatly decreased invalid signal, also reduces the computing resource afterwards needed for calculating/analysis, for example, the meter in high in the clouds Resource is calculated, also, also reduces the human cost for needing to intervene, quite with advantage.

However, be distinguishingly, when the application purpose of device is different, it is also possible to be embodied as opposite situation, citing and Speech, the purpose of one of which physiology of exercise monitoring device is to be to continue, produce heart rate information without interruption, therefore, works as discovery When having violent mobile, luminous intensity can be strengthened on the contrary, to therefrom tell heart rate spy as much as possible by improving S/N ratios Levy, therefore, when signal quality is low how to change luminous intensity has no certain limitation, can be different according to purpose and have different Selection.

On the other hand, when signal quality is high, that is, represent that the physiological characteristic of acquired physiological signal understands and S/N ratios Height, therefore nature can be more analyzed it, be no longer influenced by limitation, also therefore, it is possible to provide more detailed physiologic information content.

By taking PPG signals as an example, when signal quality is high, by it is distinguishable go out each heartbeat, accurately calculate each heartbeat Between time interval, to obtain accurate heart rate (beat-to-beat hear rate), and then draw changes in heart rate (Heart Rate variation), therefore, first, it is, real-time heart rate value to allow user to control real-time heart with most can directly providing Activity change.

Then it is then that can carry out the analysis about cardiac arrhythmia, can filters out whether have the rhythm of the heart not by analyzing changes in heart rate Whole Possible event, for example, early onset shrinks (Premature Beats), auricular fibrillation (AF, Atrial Fibrillation), The various symptoms such as rapid heart beat (Tachycardia), heartbeat excessively slow (Bradycardia), heartbeat pause (Pause), wherein, very An important symptom is auricular fibrillation, and it is the quick and irregular bounce of heart, it may be possible to of short duration a period of time, also may be used Can be long period of time, and known auricular fibrillation can increase heart failure (heart failure), apoplexy (stroke) etc. The danger of disease, therefore be a very important index.In this case, although the type of some cardiac arrhythmias can not be complete It is distinguished, for example, early onset shrinks early onset atrial contraction (the Premature atrial for including and betiding atrium Contractions, PAC), and occur early onset ventricular contraction (the Premature ventricular in ventricle Contractions, PVC) two types, still need to be judged by observing electrocardiographic wave, but by observing the change of heart rate Change, can still interpret cardiac arrhythmia Possible event whether occur, and reach the purpose screened in advance, notify user the rhythm of the heart occur Not whole correlated characteristic, and notified by such, user is to know to need to further consult with doctor, carries out more inspection in detail Look into, for example, user can be informed by way of showing the cumulative frequency of cardiac arrhythmia Possible event,

So, it is preferred that the apparatus according to the invention can provide a notification message, to occur seriously in real time User is notified during cardiac arrhythmia Possible event, however, because accidental some classification cardiac arrhythmias belong to normal physiological phenomena, Therefore, in order to not cause the puzzlement of user, it also is embodied as reaching after preset times, for example, accumulation occurs in special time More than specific times, user is just notified, before preset times are not reached, then only provided without notifying, for example, be only shown in screen The curtain number of times accumulated upper today, and this preset times can be embodied as it is built-in or by user's sets itself etc. by program, Do not limit.

Furthermore, further, by analyzing heart rate, the information of HRV and autonomic nerve activity can be obtained, and this two are believed Breath is then to have close relationship with the angiocardiopathy of many and the condition of people, for example, occurring before miocardial infarction For a period of time, for example, 2-3 days, autonomic nerve activity can become very low, therefore, if as soon as this situation can be learnt in advance, it is organic The generation of miocardial infarction can be avoided；In addition, by analyzing heart rate, can also obtain related RSA (Respiratory Sinus Arrhythmia, respiratory sinus arrhythmia) information, and then learn the respiratory variations of user, and due to by intentional Autonomic nerve can be influenceed by knowing ground adjustment breathing, therefore, by such information, and user can be helped to improve autonomic nerve activity. In addition, when the PPG sensors of use have multiple light sources, the information about blood oxygen concentration will can be obtained.

Herein, it is necessary to be with illustrating, typically when calculating HRV, when using frequency domain (frequency domain) point During analysis method, it usually needs based on the continuous physiological signal of 3-5 minutes, but because apparatus of the present invention are implemented as dressing shape Formula, therefore many fluctuations caused by body is moved are there may be in expectable acquired physiological signal or are interrupted, therefore, In particular, can be by the way of time domain (time domain) analysis, because more than 3 successive heartbeats can obtain time domain Heart rate variability rate (HRV) information virtual value of analysis, therefore can also be analyzed even if occurring signal interruption, and this analysis is to use The method of statistics, sequential relationship not necessarily, consequently, it is possible under relatively low signal quality, still can carry out time-domain analysis to take The related physiological information of HRV and autonomic nerve activity is obtained, is quite suitable method.

Then, then by taking electro-cardio signal as an example, because electrocardiogram is that most traditional heart rate obtains source, therefore, above by The information that analysis PPG signals obtain heart rate and can provided, be also all by analyzing the content that electro-cardio signal can be provided, for example, Real-time heart rate, related cardiac arrhythmia information, HRV and autonomic nerve action message, and correlation RSA information etc., therefore herein i.e. not Repeat.

And compared to pulse wave signal, the maximum feature of electrocardiogram is that it can provide heartbeat waveform, therefore, the heart is being judged When rule is not whole, so that it may whether exception occur by observing the shape of P ripples and/or QRS wave in electrocardiographic wave and judge that contraction is Position from ventricle or atrium, and PAC and PVC is clearly differentiated, in addition, whether will also realize that has beyond cardiac arrhythmia Symptom, for example, can be known whether with myocardial infarction symptoms by observing ST values (ST level), or observation QRS wave shakes Width and known whether ventricular hypertrophy etc..

Here, it should be noted that second calculation formula selection it is equally unrestricted, can be above-mentioned any combinations, Especially, the physiologic information that can be provided due to the second calculation formula is more detailed, and therefore, user can have more spatial choices The physiologic information content that oneself needs, is not limited completely.

In addition, when selecting the second calculation formula because of signal quality to be high, also can be real in addition to above-mentioned various analyses Apply as in the physiological signal species more than one of input, it may for example comprise there is provided can only analyze when PPG signals and electrocardiogram The selection of one of which physiological signal, for example, only PPG signals are analyzed, or selection analysis electrocardiogram etc., to provide more Meet the information of demand.

In addition, although in narration above, the offer of the first physiologic information is main when signal quality is low, but It is preferred that first physiologic information also can physiological signal quality for it is high when provide, and allow user to obtain more information, It can be then embodied as by user's sets itself, or lead at any time in when providing respectively as first and second physiologic information Cross manual mode start etc., visual use demand and it is different, do not limit.

Furthermore, it should also be noted that ground is, selection uses the first calculation formula (signal quality is low) and the second calculation formula (signal matter Amount is high) basis be in real time, that is, being determined completely in accordance with acquired signal quality, without the limitation of specific period.

As to how information (including signal quality information, physiologic information, and notification message etc.) is supplied to user, Then there are many selections.Firstly, since the device of the present invention is implemented as being worn on the form with user, therefore, wherein one Kind of preferred mode is also to be worn on information offer interface with user, for example, by combined with device or with wearing The mode that structure is combined, consequently, it is possible to which user, which just only needs to single wearing action, can complete all settings, here, can The information providing formula of selection includes tactile, the sense of hearing and/or the appreciable form of vision, for example, vibration, sound, voice, hair Light, color change, text importing etc., it is unrestricted, for example, can be by setting vibration module, sounding component, light-emitting component shows Show element etc. and reach, wherein being especially advantageously, by the way of vibration, because the apparatus according to the invention is intended to Continuous physiological status monitoring is performed, therefore, more than user can wish device being worn on compared with background, and vibration is It is best suitable for one of information providing formula of such a situation.

Or, alternatively, information also can be supplied to user by an external device (ED), for example, according to the present invention Device the information transmission provided can be intended to by wired or wireless mode to the external device (ED), and pass through the external device (ED) institute The information having provides interface and provides information to user, for example, the external device (ED) can be intelligent mobile phone, flat board meter Calculation machine, the portable electronic devices such as intelligent watch, and with the apparatus according to the invention by modes such as earphone jacks or bluetooth Be connected with each other, consequently, it is possible to can also be used vibration, sound, voice is luminous, color change, the mode such as text importing and allowing makes User learns the physiological status of oneself in real time, same quite tool convenience.

Furthermore, also having is advantageously, and the apparatus according to the invention can further provide for a triggering button, to allow user can In the physiological status for being intended to learn itself, actively start the offer of information by the action for pressing or touching, rather than passively Wait.

In addition, about the processing to signal, also there is a variety of possibility.For example, in a preferred embodiment, can be by dressing Device with is calculated, analyzed and information offer；Or, in a further preferred embodiment, when being embodied as and outside dress Put when being connected (can be wired or wireless connection), device that can be with being worn on is calculated, analyzed, and by outside Device provide information, or can by real-time Transmissions such as acquired physiological signal, signal quality related informations to external device (ED), and Calculated, analyzed and information offer by external device (ED)；Or, in a further preferred embodiment, signal can first be stored down Come, row is calculated, analyzed again after remaining, for example, the detection carried out during sleep, it will usually adopt the mode stored in advance, and In this case, physiological signal can be stored directly in device, for example, can be stored in internal memory, then passed by wired or wireless Defeated mode is transmitted to external device (ED), or can be stored in SD card, then is read the mode of SD card by external device (ED) and obtained stored Data, or can also transmit to external device (ED) and stored, as signal quality related information, then also can in advance store, treat Signal performance figure/grade etc. is just determined during ex-post analysis, or, signal performance figure/grade can be also determined in advance and is marked In on acquired physiological signal, do not limit.

In another embodiment, acquired physiological signal, signal quality related information are then sent to high in the clouds Stocking system, then big data computing is carried out by high in the clouds, for example, can directly be uploaded by object wearing device or by the external device (ED) Connect network and be uploaded to a network servicer, and the form that upload in real time can be embodied as or uploaded again after first storing, do not have Limitation, in addition, the network servicer can also produce report after computing is carried out according to physiological signal and/or signal quality information Accuse, to allow user to more clearly understand testing result.Accordingly, there can be various possible embodiments, can be according to reality Demand is different and changes.

Due to it is an object of the invention to provide continuous physiology monitoring, for example, the long-time monitoring of 8 hours, 24 hours, therefore Inevitably, substantial amounts of data volume can be produced, is stored in device, and when needing to carry out data transfer described above, especially It is that when being carried out by wireless transmission method, the size of data volume will directly affect the time of transmission, in this case, according to this The signal Quality estimation program of invention can bring the advantage for shortening transmission time.For example, in the signal by the present invention After Quality estimation program, if find signal quality it is not good, just it has been observed that may take, for example, reduction sampling rate, stop sampling, Stop recording/storage physiological signal and/or handle the means such as physiological signal using the mode of reduced sampling, therefore on the one hand can save Electricity, on the other hand can also reduce data volume, and reduce data volume in addition to influence storage area and computing resource, also quite weigh Strategic point is exactly to shorten data transmission period because, except long-time monitoring inevitably data volume greatly in addition to, when with a variety of lifes When managing sensing element, data volume will be multiple growth, therefore, be effectively reduced data volume and will be helpful to significantly reduce transmission Time, especially, object wearing device now is mostly to use wireless transmission method, for example, bluetooth, to reduce the complexity of wiring, therefore Its data transfer bandwidth can be limited to more, if data volume can not be reduced effectively, it will waste the substantial amounts of time in data transfer.

In addition, further, can also decide whether to be transmitted according to the result of signal Quality estimation, if for example, Judgment result displays physiological signal quality is excessively poor, then can be embodied as not sending data to external device (ED) or network servicer is carried out Calculate (no matter whether data volume has been reduced), equally computing resource can be saved by such mode.

So far, by way of the present invention also obtains quality related information while obtaining physiological signal so that physiology The processing routine of signal has dynamically been adapted to according to signal quality, ensures to be supplied to the physiology of user to believe to maximize The correctness of breath, also, can also change the sample program of physiological signal according to signal quality, further change physiology in real time The mode of operation of monitoring device, to reach power saving, reduce data volume and storage area, shortening data transmission period and saving The multiple effect such as computing resource.

When actually implementing, in order to obtain continuous signal, the apparatus according to the invention can be dressed by a wear structure With user, knot is worn for example, structure, pectoral girdle, paster, clothes, neck can be worn structure, wrist being worn by wearing structure, glasses, ear Structure, arm wear structure, refer to and wear structure etc., and it is first-class to be arranged at head, ear, chest, neck, wrist, arm, finger or finger tip Position, is not limited, species that can be according to the physiology sensing element for obtaining physiological signal and the position to be set, and user Actual demand and change.

In addition, the apparatus according to the invention can have a housing, by circuit (for example, being generally used for physiological signal capture Analog signal processor, analog-digital converter, filter, amplifier of equipment etc., are omitted herein) it is placed in wherein, then by Wear structure carrying is arranged at user, or, alternatively, circuit can be also directly arranged in the wear structure, without Housing is set in addition, in addition, the physiology sensing element may be disposed on housing, on wear structure or passes through a connecting line and extends And go out, also without limitation.

When using PPG sensors, included according to the position that the cardiovascular activity monitoring device of the present invention can be set, but It is not limited to, head, ear, neck, wrist, arm, finger and chest etc., its mode measured is that photocell is launched The light of specific wavelength enters skin underlying blood vessels, and light is connect after penetrating blood or being reflected through blood by an optical detector Receive, and blood flow is learnt because of the change produced by heartbeat by analyzing the change of light absorption value, to push away to obtain changes in heart rate.Cause This, as long as the position that can obtain blood physiology signal by PPG sensors all belongs to the application category of the present invention, does not limit.

Or, electrocardioelectrode can be also used, to obtain electrocardiogram, in this case, according to the cardiovascular activity of the present invention The set location of monitoring device includes, but not limited to head, ear, neck, arm, wrist, finger and chest etc., citing For, conventional patch electrode can be used, pectoral girdle can also be used two electrodes is arranged at chest, or it is each by adapting to human body The various wear structures at position and two electrodes are arranged at user, to reach the continuous purpose for obtaining electro-cardio signal. Therefore, as long as the embodiment of without prejudice to user all belongs to the application category of the present invention, do not limit.

Certainly, can also have multiple physiology sensing elements simultaneously, for example, PPG sensors and the heart can be set simultaneously Electrode, or multiple PPG sensors (for example, arm and wrist, or wrist and finger etc.) of diverse location are respectively arranged at, And set by such, so that it may by the comparison and/or correction between two signals, and make the offer of information more elastic, For example, when only one signal occurs abnormal, the abnormal signal of the appearance can be given up after the comparison, consequently, it is possible to quality Index will not be lowered, also will not therefore and initial second calculates the calculating of formula, user still can obtain more letter Cease content.

Furthermore, when with multiple physiology sensing elements, one of physiology sensing element also is embodied as only specific Carry out signal capturing is just activated under situation.For example, in a preferred embodiment, according to the dynamic heart of the Wearable of the present invention Angiokinesis monitoring device can have PPG sensors and electrocardioelectrode simultaneously, and implementation is, when usually with wearing When, although electrocardioelectrode has contacted skin, but only constantly obtains heart rate information by the PPG sensors, for example, quality refers to Number for it is low when provide average heart rate, and performance figure for it is high when real-time heart rate is provided, cardiac arrhythmia Possible event, and restraining oneself Nervous activity situation information, and electrocardioelectrode be then enabled only when the performance figure is shown as high, just be it is usable, also It is that electrocardiogram is only just measured at steady-state, to allow under stable state the information that can be provided more polynary. This, the measurement of the electrocardiogram can then be embodied as automatically beginning to, or set the opportunity of enable by user, or by using Person manually boots, and does not limit.

Or, in a further preferred embodiment, at the same time with PPG sensors and in the case of electrocardioelectrode, work as basis The present invention device be worn on when, at least one of the electrocardioelectrode is embodied as not in contact with skin, but is allowed and used Person, which decides in its sole discretion, to be contacted manually whenever necessary and measures electrocardiogram, for example, when device be arranged at head, ear, Neck, wrist, finger, on arm when, on the inside of the wear structure that an electrode can be arranged to contact skin, and another electrode Then it is located at the position that can be contacted by outside, therefore, when in need detected, user can pass through hand face contact Outer electrode or mobile device and act other positions of external electrode contact body etc. and reach the measurement of electrocardiogram.

And in particular, above-mentioned mode is particularly suitable for the monitoring of cardiac arrhythmia, as mentioned earlier, PPG sensors Whether there is cardiac arrhythmia Possible event available for monitoring and screening, it is therefore, continuous in PPG sensors by such configuration In the case of obtaining pulse wave signal, by performing the second expression formula, it can know whether cardiac arrhythmia Possible event occur, this When, as long as providing interface notification user by information finds cardiac arrhythmia Possible event, so that it may remind user to carry out in real time Electro-cardio signal is detected, for example, by modes such as vibration, sound or screen displays user can be notified cardiac arrhythmia occur Possible event, and after user is notified, need to only lift the exposed electrode of hand contact can start electro-cardio signal acquisition, so One, it not only can confirm whether cardiac arrhythmia really occurs, the electrocardiogram that may occur problem can be also recorded in real time, is quite had Help doctor in being understood and judged afterwards.However, as previously described, because accidental some classification cardiac arrhythmias belong to normal Physiological phenomenon, therefore, in order to not cause the puzzlement of user, just the cardiac arrhythmia that can also implement particular category is given notice, be Reach after preset times, for example, accumulation there occurs more than specific times in special time, just notify user, not up to default Before number of times, then only provide without notifying, for example, the number of times that today has been accumulated on screen is only shown in, and this preset times can It is embodied as built-in or by user's sets itself etc. by program, does not limit.

Moreover, using such a mode another advantage is that, can be big in order to understand the stored data volume got off afterwards The reduction of amount.Although electrocardiogram can provide most detailed heart activity information really, relatively, also illustrate that its data volume compared with Greatly, therefore, in the case where needing the demand of long-time continuous monitoring, such mode, so that it may ensuring that important cardiac event do not lose While being recorded to leakage, mass storage space and computing resource are also saved, can also shorten data transmission period.

So, it is preferred that according to the notification message of apparatus of the present invention, can also implement to notify user to carry out manually Ecg measurement, and can then there be various possibility on the generation opportunity of the notification message, for example, when the performance figure is shown as high When, notify user to be appropriate for the acquisition of electro-cardio signal now, or, sent out after the signal acquired by PPG sensors is analyzed When existing heart rate occurs abnormal, for example, when there is cardiac arrhythmia Possible event, notifying user to carry out that more information can be provided manually The measurement of electrocardiogram signal etc., be all possible situation, it is unrestricted.

In addition, further, when there is PPG sensors and electrocardioelectrode simultaneously, due to pulse wave can be drawn from heart Reach the time needed for the sensing the feedback of position of optical sensor, that is, so-called pulse wave passing time (Pulse Transit Time, PTT), its known arteries hardness with influenceing blood pressure height is relevant, adds, by the way that PPG sensors are arranged at into difference Position, can by calculate two at pulse wave transmit time difference and obtain related pulse wave velocity (Pulse Wave Velocity, PWV) information, consequently, it is possible to by can by its between pressure value specific relation and calculate the blood pressure of reference Value.

Accordingly, according to idea of the invention, first, with device is worn on by user, and physiology sensing element is completed Setting, to start the acquisition of physiological signal and quality related information；Then, it is related comprising physiological signal and quality when receiving After the input of information, processor judges signal quality to be high or low immediately, and the decision calculation to be used in this, as basis Formula, and after computing, the information that immediately can draw current signal quality is supplied to user, and when signal quality occurs During change, processor is to rejudge adoptable calculation formula automatically, and provides corresponding physiologic information in real time to user.Cause This, by such flow, user need to only put on device, place physiology sensing element, and proceed by monitoring, The action of itself need not be paid special attention to, need not need to more be detected because symptom is occurred in that using another table apparatus in a hurry.

For example, user can be in the situation for wearing the dynamic cardiovascular activity monitoring device of Wearable according to the present invention Under be engaged in motion, for example, jog, and during movement, because processor voluntarily can judge to be taken according to performance figure Calculation formula why, for example, when running, the Oscillation Amplitude for being likely to result in device is excessive, cause signal Quality Down, because This, the information that user can see may be limited only to the numerical value of the non real-time reaction physiological status such as average heart rate, and be accused when running After one paragraph, user stop rest when, because user no longer moves, signal quality is high, now, it is possible to which having more has User can be supplied to by closing cardiovascular information, for example, heart rate in real time, the information of related cardiac arrhythmia, relevant HRV and self-discipline Neururgic information, and the information etc. about breathing, and the time just moved, to be also user most took notice of the heart of oneself When vascular condition, even more send out the time of cardiac problems well, such device can meet completely the demand of user there is provided Convenience.

In a further preferred embodiment, user can live wearing the Wearable dynamic angiocarpy according to the present invention during sleep Dynamic monitoring device, for example, on head, in wrist or finger is first-class, with the collection of lasting progress signal during sleep.In this feelings Under shape, firstly, since during user is in sleep, therefore, compared to real-time display, it can be more desirable to record the whole night Signal, for waking up relief user or medical personnel are diagnosed, for example, can by analyze electrocardiogram and/or by PPG sensors obtain heart rate information and see whether occur cardiac arrhythmia, can also obtain HRV and learn autonomic nerve activity feelings Shape, and then judge sleep stage, Depth of sleep etc..

In addition, also the change of blood oxygen concentration can be recorded in the case of the PPG sensors used have multiple light sources Change, to judge whether to occur Sleep Apnea event, for example, apnea (Apnea) and shallow breathing (Hypopnea), and What respiratory variations were directly affected is exactly the oxygen concentration in blood, therefore, is changed by acquired blood oxygen concentration, so that it may will The dynamic cardiovascular activity monitoring device of the Wearable of the present invention is applied to the detecting of Sleep Apnea event, more increases it practical Property.

Here, alternatively, in addition to using wearing form, the sensor using other forms is well suited for, for example, mattress Pressure sensor can be also obtained because the vibration produced by heartbeat or the electromagnetic induction device of bedside can be measured because of electrocardio institute Electromagnetic field change of generation etc..

Furthermore, by the content of the quality related information, the sleep situation of user can be also learnt, for example, can be by dividing The mode of heart rate signal is analysed, or in the case of using action sensing element, cither indirectly or directly obtains the letter of body movement Breath, for example, the frequency stood up, and then judge the quality of sleep quality etc., therefore, except the offer originally having is cardiovascular related Outside the function of information, need to only carry out different analyses to the signal that script is provided, so that it may further provide relevant sleep quality, The information of Depth of sleep.

Moreover, tool is advantageously, by the signal quality record according to the present invention, medical personnel are in deciphering/analysis afterwards During signal, the time for watching the not good signal of quality can be reduced, for example, user is possible to causing life during sleeping because mobile Reason sensing element is released, and this can be clearly reacted in signal quality record, therefore, and medical personnel only need to be before deciphering/analysis First understand the integral status of signal quality, or the signal quality that each signal section of observation is marked, and select signal quality The section of analysis is sufficient for, time and resource can be largely saved.

In another embodiment, user being loosened, biofeedback or during respiratory training, with having on root According to the dynamic cardiovascular activity monitoring device of the Wearable of the present invention, now, because body is in static state mostly, therefore can be pre- Heart rate signal quality acquired by phase is of a relatively high, also therefore more physiologic information can be obtained, for example, the real-time heart can be obtained Rate, HRV changes, the activity situation of autonomic nerve, and breathing situation etc., and these be all then loosen, biofeedback and/or The physiologic information of change occurs in respiratory training program, therefore, is quite suitably applied these programs and reaches effect to understand Really.

In another preferred embodiment, user can wear the dynamic painstaking effort of Wearable according to the present invention in daily life Pipe movement monitoring device, except can long-term record be used as health control, by even connect to the Net, for example, can be embodied as wearing The device direct networking with is worn, or is networked by an external device (ED), acquired cardiovascular relevant information can be transmitted To long-range, for example, remote medical nursing center or medical personnel, for example, can regularly upload data, or, also can be in detecting When being gone wrong to heart, for example, it was discovered that during cardiac arrhythmia Possible event, the situation that heart goes wrong in real time notifies remote Journey, or, by setting up danger button on device user can also be allowed to press and SOS, it is unrestricted.

Therefore, by way of obtaining signal quality related information and determining signal quality, the apparatus according to the invention is just Different information can be provided under different operating conditions, and the use for allowing user to be achieved with maximum by same device is imitated Benefit.

Possible embodiment during actual implement is illustrated below.

First, ear also is embodied as according to the cardiovascular activity monitoring device of the present invention and wears form, and physiology sensing element Then it is embodied as while having PPG sensors and electrocardioelectrode.

In the life of modern, the use of earphone is more and more universal, is especially taking the popular vehicles, walking phase Between, music often is listened very much using earphone, therefore, form is worn using ear and does not show lofty not only, can also be incorporated naturally in daily life, and And, it is more advantageously the form that is embodied directly as being combined with earphone, for example, with for listening the earphone of music, or being used for Receive soniferous ear microphone etc. to be combined, and be also not necessarily limited to be that bilateral ear is worn or unilateral ear wears form, or use earplug Or ear-hang form, consequently, it is possible to which also interface directly can be provided by the use of earphone as information, by physiologic information, notification message etc. User is supplied to, quite has convenience.

In the case of form is worn using ear, the set location of PPG sensors and electrocardioelectrode wears structure not according to ear With there is many selections, and the position to be illustrated herein is, refer to shown in Fig. 2 auricle (auricle, also referred to as Pinna) structure, wherein, in the cymba (superior concha) and cavity of concha (inferior concha) of auricle inner face Around, have from concha auriculae bottom (concha floor) (that is, parallel to plane of head) and connect up to anthelix (antihelix) and antitragus (antitragus) a vertical area, referred to as concha auriculae wall (concha wall), this ear Native physiological structure just provide a continuous level perpendicular to concha auriculae bottom, in addition, being next to below concha auriculae wall, be located at Intertragic incisure (intertragic notch) between antitragus and tragus, and close to tragus (tragus), equally There is provided the contact area perpendicular to concha auriculae bottom.

When using this region as electrode contact locations, the strength required for fixed electrode, it will be parallel to concha auriculae bottom The strength (namely strength perpendicular to the concha auriculae wall direction) in portion, especially, when being embodied as earplug form, passes through earplug and auricle Strength is supported between the projection and depression of inner face, just can reach steady between physiology sensing element and this vertical area simultaneously naturally Fixed contact, is using upper suitable tool convenience.

In addition, the contact position at the auricle back side also has same advantage, especially general common ear hook structure is when implementing Generally one part all can be set in the front and rear of auricle respectively, and reach and be fixed on by interaction force between the two Effect on auricle, therefore, when the contact position of physiology sensing element is selected at the auricle back side, will conform exactly to interaction The force direction of power, it is natural with regard to the steady contact between electrode and dorsum auriculae surface skin can be reached.

Accordingly, in this embodiment, when PPG sensors are embodied as wearing structure by the ear and be arranged on ear and/or When near ear, its set location can Yi Erdai structures actual implementation situation and change, be embodied as example, wearing structure when the ear During earplug form, it may be placed between interior duct, duct mouth, cavity of concha, cymba, concha auriculae wall, concha auriculae bottom, tragus, tragus The positions such as incisura, antitragus, that is, earplug is arranged at the position that can contact during auricle inner face, or, when the ear wears structure reality When applying as ear-hang form, PPG sensors may be placed on ear back part, so that from the auricle back side, V-type is recessed between auricle and head Fall into, or head near auricle obtains signal, or, it also is embodied as the structure that earplug coordinates ear-hang, then or, it can also implement For the form of ear clip, to be located on ear-lobe, therefore, do not limit.

As for electrocardioelectrode, exemplified by two, one of electrocardioelectrode is embodied as being located at, when the ear wear structure setting in The position that can be contacted when on ear with the skin of head near ear or ear, consequently, it is possible to wear structure by dressing the ear Action can complete the contact of electrode, and settable position is then identical with above-mentioned PPG sensors, for example, in ear-lobe, duct, Duct mouth, cavity of concha, cymba, concha auriculae wall, concha auriculae bottom, tragus, intertragic incisure, antitragus, the auricle back side, auricle and head Head etc. between cranium near V-type depression and/or auricle, also therefore, this electrocardioelectrode can be embodied as mutually tying with PPG sensors Close.

And the setting of another electrocardioelectrode then has multiple choices, for example, it can be similarly provided at the ear and wear structure On, but the position not contacted with skin near ear or ear, to allow electrode that exposed state is presented, thus user can be allowed sharp Contacted with upper limbs, for example, finger is touched, as shown in Figure 3 a, in this case, as long as user is when needing to measure Touching electrode of raising one's hand 10, so that it may obtain electro-cardio signal in real time, quite facilitates, and the especially advantageous profit of such set-up mode It is continuously to be detected with PPG sensors with mode, and persistently according to signal quality information, providing real-time physiological information and giving makes User, with allow user can in need, for example, when there is cardiac arrhythmia symptom, detect in real time and record electro-cardio signal, The actual physiological status of understanding is not only helped, the post-event diagnosis of doctor is more conducive to.

Or, alternatively, another electrocardioelectrode can be also set to other positions of body, example by connecting line Such as, shoulder neck, chest, arm, wrist, finger etc., now, if coordinating another wear structure again, two electrocardioelectrodes are The contact between skin is all maintained by wear structure, for example, neck wears structure, arm wears structure, and wrist wears structure, refers to and wears structure (as shown in Figure 3 b), pectoral girdle etc., captures consequently, it is possible to can be achieved to continuous electro-cardio signal, can be determined according to signal quality information Surely why and whether to be supplied to the physiologic information of user will store acquired electro-cardio signal etc., with reduce data volume with And required storage area, in addition, along with signal quality can be marked on electro-cardio signal, flower needed for ex-post analysis can also be reduced The calculating that takes, time resource, quite with advantage.

Here, it is noted that two ears are all the positions for the setting electrocardioelectrode that can be selected, however, through experiment After learn, the contact position of exposed electrode or extension electrode has considerable degree of influence for signal quality, wherein, work as upper left When limb touches exposed electrode or when extension electrode is arranged at left upper extremity, the quality of the electrocardiosignal obtained is much better than the contact right side Signal acquired by upper limbs, especially contacting left ear and left upper extremity respectively with electrode has optimal signal quality, therefore, to connect When touching the mode of ear and carrying out electro-cardio signal measurement, exposed electrode or extension electrode preferably are contacted using left upper extremity, with Avoid because contact right upper extremity and caused by signal quality it is bad, and then cause analysis produce erroneous judgement.

First, in a preferred embodiment, as shown in figure 4, the apparatus according to the invention, which is embodied as neck, wears form, used Physiology sensing element be a PPG sensors.

Here, as shown in FIG., in particular, different from general common PPG sensor set locations, for example, finger tip, Ear-lobe, in this embodiment, PPG sensors are incorporated into the neck and worn in structure, and wear structure by the neck and be arranged at neck Portion rear, to carry out the acquisition of continuous pulse wave signal.

When determining the measurement position of PPG sensors, need most consideration is the signal that can be obtained in the position Intensity and quality, because it has strong influence to analysis result, therefore it is considered herein that under, learnt via experiment test, work as use When neck wears form, neck wears the physiological location that structure can be touched, then fit neck wear be after structure and the characteristic of human contact, neck can The position of intensity height and the good PPG signals of quality is obtained, therefore, the present invention is effectively measured using this novelty of neck rear Position as PPG sensors set location.

It is the ornaments that can be worn in common people's daily life to be additionally, since necklace, the form worn by neck, and user can be Used naturally in daily life, do not show lofty, also do not increased burden moreover, being used even if long-time, therefore be quite suitable for The continuous detecting of physiological signal.

Here, the PPG sensors can be by way of being directly combined to the neck and wearing in structure, or as shown in figure 4, it can pass through Neck rear is arranged at reference to the mode on the housing that structure is carried is worn in the neck, regardless of whether using which kind of mode, compared with It is that, using the material and/or structure for meeting neck rear ergonomics, for example, the neck, which wears structure, can be embodied as length goodly Degree is shorter, just around neck, reduces displacement, or, the part that the neck can also be worn to form touch neck rear is embodied as symbol Close the curvature of neck and/or be made of elastic material, for example, silica gel, rubber, foam, memory metal, deflection plastics material Matter etc., it is conformable to increase, displacement is reduced, in addition, similarly, it is preferred that when PPG sensors are disposed on surface of shell, shell The curvature and/or housing that the shape of body is embodied as meeting neck are made of elastic material, therefore, are not limited, as long as can increase Plus PPG sensors are arranged at the mode of the stability at neck rear and belonged to the scope of the present invention.

Or, alternatively, structure can be also worn by the neck and a housing is placed in front of clavicle lower section, front or belly, Therefore, the PPG sensors after the pulling force brought by the housing and its content weight, neck can obtain stable strength, This is, it is necessary to be noted that, in this case, PPG sensors can be still arranged at after neck by housing, all has housing before and after being formed Situation, it is therefore unrestricted.

Furthermore, as long as being equipped with vibration module, sounding component, light-emitting component, display element etc., so that it may in real time by correlation Physiologic information be supplied to user, for example, by modes such as vibration, sounding, color change, text importings, quite facilitating.

In addition, further, device is worn according to the neck of the present invention and also is adapted for setting electrocardioelectrode, to obtain electro-cardio signal, Here, can be embodied as only being separately provided electrocardioelectrode, or it also is embodied as setting together with PPG sensors, does not limit.

Furthermore, glasses form also is embodied as according to the cardiovascular activity monitoring device of the present invention, wherein, physiological sensing member Part is embodied as while having PPG sensors and electrocardioelectrode.

In recent years, glasses have been no longer confined to A nearsighted person's wearing, are increasingly becoming ornamental part, in being common people's daily life Accessory common and being commonly used, therefore, similarly helps to be lifted the acceptance of user using glasses form.Described at this Glasses structure refer to, be arranged at by auricle and nose as the strong point on head and can be with head and/or the skin of ear Skin produces the wear structure of contact, therefore, is not limited to general Glasses structure, is also deformed including it, for example, Ke Yishi Have the structure of grip force to head both sides, or be embodied as the asymmetric form of both sides mirror pin, for example, one side mirror pin has in auricle rear There is bent portion, another side mirror pin does not have bent portion only frame then above auricle, also, can not have eyeglass, therefore yet, there is each Possibility is planted, is not limited.

PPG sensors may be disposed on Glasses structure the position for pressing close to head and/or ear, for example, the bridge of the nose, mountain root, two Region between eye, temple, the auricle back side, V-type is recessed between auricle and head, and the head near auricle etc.；As for electrocardio electricity The setting of pole, and foregoing similar, an electrocardioelectrode can be arranged at into Glasses structure can contact with head and/or ear skin Position, for example, the bridge of the nose, mountain root, region between two, temple, the auricle back side, V-type is recessed between auricle and head, and auricle is attached Near head, therefore, is further embodied as being combined with PPG sensors, and another electrode 10 then may be disposed at Glasses structure Exposed surface is touched for the hand of user, as shown in Figure 5 a, or extends other portions of contact body using connecting line Position, for example, shoulder neck, chest, arm, wrist, finger etc., and when also can further coordinate another wear structure and reach long Between set electrode possibility.
