Therefore, for these above-mentioned shortcomings, the improvement of further proposition is Handheld electrocardio detecting device, and it does not need the dry-type electrode that is pasted on it by adopting and solve and by device extended wear in puzzlement with it, and must simplify complexity when detecting.If application number is for disclosed in the U.S. Patent application of US7149571 and US7197351, Handheld electrocardio detecting device is provided with dry-type electrode on the surface of device, ECG detecting can be carried out by contacting the mode of hands and/or body surface at any time when there being demand, therefore, no longer be limited to and wear in time with it and attachment of electrodes, therefore can have more and be flexibly used for the situation of monitoring of cardiac, and, such ECG detection device is also configured with analysis programme and display screen usually, user can be allowed instantly namely to learn testing result what measure, need not by the time hold a consultation to hospital, therefore, quite be applicable to using at home, and, also provide and have the user of heightened concern regularly can understand the simple and easy approach of heart situation at ordinary times voluntarily to self health of heart.
Afterwards, along with the electronic installation carried with, such as, popularizing of smart mobile phone, what occur in recent years is the ECG detection device combined with mobile phone, disclosed in US8615290, itself and Handheld electrocardio detecting device are similar, be adopt dry-type electrode equally, so difference only carries out the manipulation of device at the operation interface by mobile phone, such mode allows the user of monitoring of cardiac demand can reduce the quantity of the device carried with.
Just, no matter above-mentioned be the ECG detection device of hand-held form or the form that combines with mobile phone, although can carry with, but operate owing to must be gripped by hands, therefore under the demand meeting ergonomics, add and need to show result, cannot be too small in size, carry and be still certain burden; And, with it electrode is not arranged at always, therefore, during for detecting, needs more step, such as, starting shooting again after first withdrawing device, could start to detect, therefore also likely therefore miss the opportunity of detection.
And, the mode of carrying out measuring with both hands is easy to the phenomenon occurred when measuring as instability such as hand shakes, thus measured electrocardiogram is caused to occur the situation of the impact analysis such as baseline drift, waveform distortions, moreover, when user wish hand remain stable and muscular tone or specially firmly to guarantee with electrode Contact time, be also easy to because of the firmly electromyographic signal of the signal analysis that has an impact.
Therefore, have and need a kind of Wearable ECG checkout gear, can solve the aforesaid drawbacks, allow user while more convenient use, also can be down to minimum by the impact of various uncertain factor during operation.
And, when ECG detection device is wearable in it time, other physiologic information is just obtained further by acquired electrocardiosignal, such as, the time series of eartbeat interval can be obtained according to electrocardiogram, to carry out HRV (HeartRateVariability, heart rate variability rate) analyze, and learn the activity situation of autonomic nerve, also relevant RSA (RespiratorySinusArrhythmia is obtained by analyzing this time series, arrhythmia) information, and then learn the respiratory variations of use, and by these information, the respiratory training contributing to improving autonomic nerve balance is carried out with regard to bootable user.
Because one of ARR important origin cause of formation is vegetative dystonie, therefore, when user wishes electrocardiogram when be there is arrhythmia under real time record by the ECG detection device of Wearable, if same device can provide the function improving arrhythmia symptom, for user, it will be more total solution.

Wherein, this Circuits System can be embodied as and be placed in this wear structure, or, further, also can comprise a housing again according to device of the present utility model, now, this Circuits System just can be placed in this housing and/or this wear structure, therefore, implement situation by reality and determine, not restriction; In addition, the material of this housing be then can be embodied as with this wear structure identical or different, such as, if when being embodied as identical material, the form of the molding that just can form as one, in addition, if when being embodied as unlike material, just can selecting the material be applicable to according to the difference of wearing position, not limit equally.
In addition, owing to being the form being embodied as wearing according to ECG detection device of the present utility model, therefore, this information provider unit provides the mode of information can have more selection, includes, but are not limited to, the modes such as vision, audition and sense of touch, for example, this information provider unit can be embodied as display element and/or light-emitting component, provides information to utilize the modes such as text importing, graphic change and/or cresset change; Or this information provider unit also can be embodied as sounding module, to provide information by the change of sound frequency or volume or the mode of voice; Or this information provider unit also can be embodied as vibration module, and utilize the variation pattern such as power, length as vibration and information is provided.
Moreover, this information provider unit also can be embodied as further, information is exported to an external device (ED) via a wire transmission module or a wireless transport module, give user this information to be provided by this external device (ED), wherein, this external device (ED) can be, but being not limited to, a PC, a smart mobile phone, a panel computer or an intelligent watch etc., need be only the device that this information can be supplied to user, therefore, not restriction.
According in Wearable ECG checkout gear of the present utility model, in particular, this first electrode be embodied as be positioned at when whole ECG detection device to be arranged at by this wear structure user with it time, one of user skin can be contacted on the surface, that is, contact between this first electrode and skin realizes by wear structure is arranged at action with it, therefore, when user need not exert a force voluntarily, this first electrode just can realize and contact between skin, therefore the myoelectricity interference that the muscular tone brought because of operational motion causes can be considerably reduced, quite contribute to obtaining good signal quality.
As for this second electrode, it is then have several selections implemented, such as, can be embodied as be positioned on device except this surface another on the surface, touch for other partial skins of user, such as, hands refers to, the skin of the part such as chest, and be with should be noted that, in order to arrange the surface of this first electrode and another surface in order to arrange this second electrode, it can be arbitrary surface of this wear structure, or arbitrary surface of this housing, not restriction, only should be noted, this first electrode and this second electrode can not contact user with it with the skin of a part.Or, alternatively, also can be embodied as and be arranged at it user by another wear structure, just can utilize the positive force of wear structure equally thus and realize and contact between skin, therefore, not restriction.
Accordingly, in use, with it user will be arranged at according to Wearable ECG checkout gear of the present utility model by this wear structure, such as, on finger, on ear or wrist first-class, and in this case, namely contact between this first electrode and skin realizes, then, when occurring measuring Electrocardiographic demand, only need again by the second electrode being touched the action of other partial skins, the loop of extracting electrocardiosignal can realize, and user can facilitate whenever necessary at any time and easily obtain electrocardiogram.
In addition, when this second electrode be also embodied as to be arranged at by this another wear structure user with it time, with it then two wear structures only need all be arranged at by user, electrode in order to extract electrocardiosignal arranges and namely completes, therefore, user can press when there being electrocardiogram under needs record the signal extraction that start key carries out a period of time, such as, 30 seconds or 1 minute, or, the device that is extracted in that also can be embodied as electrocardiosignal is worn and to be started record after with it immediately and/or analyze, to save the action that started by press is measured in order to record sudden cardiac situation, so, not restriction, the mode be applicable to can be selected according to actual demand.
At this, similarly, this another wear structure also can be combined with another housing, this second electrode then can be embodied as equally be positioned at this another wear structure or this another housing arbitrary surface on, only need can this another wear structure be arranged at user with it time realize the contact of this second electrode and skin, therefore, not restriction.
Owing to according to ECG detection device of the present utility model being the form adopting wearing, therefore, coordinate the operation behavior that is worn on it, the startup of device and/or ECG detecting, except the mode of general power-on and/or start detection, also can there is various selection, such as, can arrange a switch at this second ate electrode, it can be triggered because of the force of the second electrode and contact skin, to make device enter the state can carrying out electrocardiosignal extraction, with then starting drive and/or ECG detecting; Or, as an alternative, can by this second Electrode connection to physical state detection unit, with the physical change that detecting electrode produces when contacting skin, and learn that whether the contact between electrode and skin is enough stable by this physical change, thus whether known device can carry out electrocardiosignal extraction, in addition, this first electrode equally also can be embodied as and be connected to a physical state detection unit, not restriction.
At this, this physical change comprises, but be not limited to, pressure change and impedance variation, for example, this physical state detection unit can comprise pressure sensing module, to learn that pressure changes, and judge that whether the pressing suffered by electrode is enough, or this physical state detection unit also can be embodied as a switch, the pressure size that electrode bears can be learnt equally, or, this physical state detection unit also can comprise impedance sensing circuit or capacitance sensing circuit, to learn the impedance of electrode, capacitance variations, and judge whether to carry out ECG detecting, therefore, unrestricted.
Therefore when judging, if this switch does not switch completely, and/or this physical change is not inconsistent unification preset range, namely represent that the contact condition between this second electrode and skin is not enough to carry out electrocardiosignal extraction, therefore, device is in electrocardiosignal and extracts the state that cannot be activated, if when this switch switches completely and/or this physical change meets a preset range, then represent the contact achieving between this second electrode and skin and be enough to carry out electrocardiosignal extraction, therefore, device is converted to this electrocardiosignal and extracts the state that can be activated.
At this, especially, also by the no switching of open relation completely or the physical change judgement that whether meets preset range carry out control electrode and whether can be used, such as, whether conducting, namely, electrode is first in not spendable state, until switch be switched completely after or after this physical change meets this preset range, electrode is just converted to spendable state, such as, switched on, thus, the definition of acquired electrocardiosignal can be guaranteed further, be more conducive to precision of analysis.
And further, after being judged as carrying out electrocardiosignal extraction, how starting drive and/or detection, has various selection, for example equally, in a preferred embodiment, can be designed to according to device of the present utility model, device can after a certain time, such as, after 3 seconds, automatically start to carry out detection electrocardiosignal; Or in another preferred embodiment, device after a certain time, such as, after 3 seconds, just can be converted to the state can carrying out electrocardiosignal extraction, afterwards, if state of can extracting still continues, then start ECG signal sampling, therefore, have various may, but actual demand and changing, not restriction.
In addition, coordinate above-mentioned startup and judgment mode, also the state being always in signal extraction can be embodied as according to device of the present utility model, but only just carry out record when electrocardiosignal feature being detected, or just adjust sampling frequency or signal enlargement ratio, record the change of all possible electrocardiosignal with more complete.
Below the better embodiment according to Wearable ECG checkout gear of the present utility model is namely illustrated.
First, according to the conception of this utility model first aspect, this wear structure is embodied as a finger to wear structure, therefore, refer to that wearing structure carried by this according to Wearable ECG checkout gear of the present utility model, and use be arranged at user one finger on, at this, can be embodied as shown in Figure 1A, the form wearing the accommodating Circuits System of structure is referred to by this, or, also can be embodied as shown in Figure 1B, this refers to wear in structure again in conjunction with the form of a housing 20, this Circuits System then can be placed in this housing and/or this refers to wear in structure, therefore, implement situation by reality to determine, not restriction.
Wherein, this first electrode 10 is positioned at when this refers to that wearing structure is arranged on finger, this device can contact with this finger skin because of wearing action one on the surface, as for 12, this second electrode be positioned on this device except this surface another on the surface, such as, can be the surface relative with this surface, or on the surface be adjacent, only should be noted it is the position that can not contact this finger skin.
At this, finger is selected to be as the main cause of the position arranging ECG detection device, refer to wear form to user, just as worn ring, be familiar with and the occupation mode that need not relearn, directly will refer to that wearing structure is incorporated into the contact pointed and can complete between the first electrode and skin, afterwards, when there being electrocardiogram under needs record at any time, the contact of other partial skins that only need carry out again beyond by this second electrode and this finger place limbs just can carry out electrocardiosignal extraction at once, and operating process and action are simply, conveniently again naturally.And by referring to wear structure to finger force, the contact between this first electrode and skin need not exert a force and can realize by user, and muscle tone can be allowed to be down to minimum for the impact of electrocardiosignal.
The mode of practical operation has many possibilities, such as, can remove to touch by another hands this second electrode being positioned at surface, as shown in Figure 2 A, or, the mode also wearing the hands of this device by mobile and touch the skin of other parts, as shown in Figure 2 B ring contacted the operational scenario of cheek, and Fig. 2 C shows electrocardiosignal extracting mode ring being contacted trunk, therefore, not restriction.
At this, in particular, due to be adopt refer to wear form, therefore user is allowed to go the mode at other positions of body contact by the mobile hands wearing this device and realize electrocardiosignal extraction loop, bring more multioperation probability, also allow user can according to the difference of environment for use and demand, and select the contact position that is applicable to, have more convenience.
So, by such concept, user can easily by contacting different positions, and obtain the electrocardiogram of different projection angle, contribute to the situation judging heart more accurately, Fig. 3 shows and generally obtains standard 12 and lead extremely Electrocardiographic contact position, by according to finger-worn type ECG detection device of the present utility model, device can be worn in left-hand finger by user easily, and by each measuring point of contact V1 ~ V6, and obtain the electrocardiogram projection of different angles heart respectively.
When carrying out ecg measurement, every two electrodes just can draw the electrocardiogram of an angle, namely, the setting position of electrode determines the projection angle of the heart electrical activity that electrocardiogram reacts, and due to heart be three-dimensional, and the cardia producing pathological changes may be positioned at any cardiac position, such as, the inspection of myocardial infarction needs to watch in ecg wave form the ST drift whether occurring occurring because of myocardial necrosis, but often cannot may be discovered under some angle because relation of position occurs for it, now, just need just likely to be checked by the electrocardiogram of different angles and draw, therefore, obtain the electrocardiogram of different angles for judging that heart disease is very helpful.
At this, the setting position of structure on finger is worn according to finger of the present utility model, be preferably the dactylus at proximal phalanx or middle phalanx place, to avoid the situation because position to occur because hand motion comes off close to finger tips, for example, this refers to wear structure can be as shown in Figure 4 A, adopt as the form of ring, or as shown in Figure 4 B, be embodied as the form deflection belt body around finger wearing housing, or as shown in Figure 4 C, be embodied as the form of only deflection belt body, or be embodied as open C type loop type, not restriction; At this, no matter adopt which kind of form, all can have the structure of adjustable collar around diameter further, to guarantee the contact stabilization between electrode and skin further, such as, ring can be embodied as and have alterable and guard against the mechanism enclosed, to adapt to the finger of different wearer, and belt body can be embodied as and has adjustable fixed position, such as, by arranging magic tape, with allow user select around time tightness etc., equally can change mode, not restriction according to practical situation; In addition, also can adopt the form of clip, to clamp dactylus or finger tip, and reach fixing effect by the elasticity of clip itself, be good selection equally.
Moreover, also the fingerstall being arranged at finger tip can be embodied as, as Fig. 4 D1, shown in 4D2, that is, one can for pointing the groove structure stretched into, such as, the form of ring-type or pothole, this first electrode is then be arranged on the inner surface of this groove structure, and, this inner surface is embodied as the surface meeting finger, to realize the contact between this first electrode and finger skin when pointing and stretching into, at this, this groove structure can made by the elastic material of tool, such as, rubber or silica gel, to realize the contact between electrode and skin, or, also can be formed as that there is plastic casing, and elastic material is set in inside and coated hands refers to, or adopt the modes such as the inside structural design exerted a force can be provided, to guarantee the good contact between internal electrode and finger tip skin, therefore, not restriction.Such form then tool advantageously allows contact diverse location seem more easy to obtain the Electrocardiographic operation of different projection angle.So, various forms can be embodied as according to actual demand according to finger-worn type ECG detection device of the present utility model, not restriction.
In addition, in a preferred embodiment, this housing 20 is also connected to this by a connecting line and refers to wear structure, and wear structure by a wrist and be arranged in the wrist of these finger place limbs, as shown in Figure 4 E, thus, wear the hardware configuration that structure is combined with finger near script is positioned at and points, such as, circuit, battery etc., can be moved in wrist, to reduce the burden of finger when wearing apparatus, and, this wrist is worn on the surface that structure and/or this housing do not contact with this wrist, also can be used as the position that this second electrode is set, the contact of user another kind is provided to select, or, as illustrated in figure 4f, also can be embodied as this to refer to wear structure and this wrist and wear in structure and all there is housing, therefore, not restriction.
Moreover, in another preferred embodiment, this housing 20 also can be embodied as and refer to that with this wearing structure combines by adapter, as Fig. 4 G1, shown in 4G2, in this case, first electrode 10 contacts right finger, and second electrode 12 contact skin near left hand wrist, and, owing to referring to that wearing structure is be placed in wrist by combining with the housing be arranged in wrist, therefore, when both hands are positioned on fixing surface by user, such as, on desktop, when measuring, highly stable measurement posture can be formed, and it is minimum to make the generation of electromyographic signal be reduced to, in addition, by the form that adapter connects, the loop of ECG detecting can be shortened, therefore electromagnetic interference noise in the environment responded to because of connecting line can be allowed to reduce to minimum, therefore, also be a kind of quite favourable selection.
Moreover, according to this utility model conception on the other hand, this wear structure is embodied as an ear to wear structure, therefore, wear structure by this ear carried according to Wearable ECG checkout gear of the present utility model, and use and be arranged on an ear of user, this Circuits System is then be placed in this ear to wear in structure, and/or in the housing comprised in addition.
Wherein, as shown in Figure 5A, this first electrode 10 be positioned at when this ear wear structure be arranged on ear time, on this device can because of wearing action with one of the contact skin of this ear or this ear near zone on the surface, as for 12, this second electrode be positioned on this device except this surface another on the surface, such as, can be the surface relative with this surface, or on the surface be adjacent, only should be noted it is the position that can not contact this ear or this ear near zone skin.At this, this first electrode 10 also can be embodied as has two electrodes, as shown in Figure 6A, and using one of them electrode as ground connection or reference electrode, to suppress common-mode noise, such as, from the noise of power supply, therefore, enforcement does not limit.
At this, ear is utilized to have an advantage to be as the position of contact electrode, ear and near be the minimum region of electromyographic signal, add the relative position relation of quite stable between itself and head, even if therefore user health during measuring occurs mobile, such as, rotate health a little or rotate neck, contact between electrode and skin still can remain stable, can not produce the interference affecting measurement result too much.
In addition, in general daily life, compared to other body parts, ear is the less position being subject to medicated clothing and covering, and can directly contact whenever necessary relatively easily, moreover, ear and skin around thereof also have the less characteristic of hair, contact between electrode and skin can light clog-free realization, therefore, is select quite easily for user.
So, when practical operation, as shown in Figure 5 B, as long as user utilizes hands to contact this second electrode of the device worn on ear, just can realize electrocardiosignal easily and extract loop, quite convenient.
In addition, in a preferred embodiment, this housing 20 is also connected to this ear by a connecting line and wears structure, and wear structure by a wrist and be arranged in a wrist, as shown in Figure 5 C, thus, originally the hardware configuration worn structure near ear with ear and be combined is positioned at, such as, circuit, battery etc., can be moved in wrist, with the burden of ear when wearing apparatus, and, this wrist wears structure and/or this housing also can be used as the position arranging this second electrode, such as, be available for users to the position of another hands contact, or the position etc. of this housing place wrist can be contacted, the contact of user another kind is provided to select, or, also can be embodied as this ear to wear structure and this wrist and wear in structure and all there is housing, as shown in Figure 5 D, therefore, not restriction.
At this, the form of implementation wearing structure according to this utility model ear can have various selection, such as, fixed form common in general daily life, the forms such as the ear-hang as shown in Fig. 6 A1-6C, earplug, ear clip, allow user not need to relearn, can very naturally be configured, therefore, user only needs, simply as worn the action of earphone at ordinary times, can complete electrode and arranging; And when being arranged on ear by electrode by above-mentioned fixed form, the contact of electrode and skin does not need user to exert a force can to realize, and the interference of electromyographic signal can be reduced to minimum, can obtain the signal that quality is good.
In addition, in particular, in a preferred embodiment, this ear is worn structure and is embodied as and utilizes the mode of magnetic force and be attached on ear, such as, can utilize across ear two parts that magnetic is attracting each other, and by parts disposed therein for electrode, and two parts can be embodied as both all has magnetic, or parts have magnetic force, and another parts can be magnetically attracted, not restriction; At this, magnetic force Ke Tong Over arranges magnetisable material in the inside of parts, or directly makes parts by magnetisable material and realize, and in addition, similarly, the material attracted by magnetic force also can be arranged at components interior or in order to forming member.
As for obtaining electrocardiosignal in which position on ear, being then not restriction, can be any position of ear itself, such as, in auditory meatus, ear-lobe, auricle inner face and the back side, such as, cavity of auricular concha, auditory meatus mouth near zone etc., helix and the auricle back side, and as shown in Figure 7, the region near ear, such as, skin etc. near ear and head capsule intersection, these positions are all can in order to contact electrode and to obtain the position of electrocardiosignal.
In addition, because setting position is ear, therefore, also be well suited for combining with earphone according to ear-wearing type ECG detection device of the present utility model, such as, wired or wireless earphone, thus, except ECG detecting can be allowed more to incorporate except daily life, also larger effect is played by the vocal function of earphone, such as, user analysis result is provided by sound and/or voice, such as, reminds and occur that electrocardiosignal is abnormal, or timed reminding user records electrocardiogram etc., more convenient.
At this, be with should be noted that, two ears be all can select wear position, but, learn after experiment, the contact position of the second electrode has the impact of certain degree for signal quality, wherein, when the second electrode is embodied as contact left upper extremity, the quality of the electrocardiosignal obtained is much better than the signal of contact acquired by right upper extremity, therefore, when carrying out electrocardiosignal in the mode contacting ear and measuring, be preferably and utilize left upper extremity to contact this second electrode, to avoid causing signal quality bad because of contact right upper extremity, and then cause analyzing generation erroneous judgement.
And, especially, according to this utility model conception on the one hand again, also can be further, this first electrode and this second electrode are embodied as and wear structure respectively by finger and wear structure with gill and realize the contact with skin, as shown in figures 8 a-8b, thus, wear structure only need be worn on ear and finger by user respectively, namely the electrode configuration of measuring needed for electrocardiosignal has been completed, quite convenient, and, two contacts between electrode and skin are all realized by wear structure positive force, more make the electromyographic signal interference caused because of muscle tone can be reduced to minimum.
At this, as shown in Fig. 8 A and Fig. 8 B, only housing can be combined with on single wear structure, or, also two wear structures all can be provided with housing, not restriction, further, Circuits System can be placed in any one wear structure and housing too ad lib, changes according to actual demand.
In addition, refer to wear except structural electrocardioelectrode except coordinating, the electrocardioelectrode be arranged on ear also can be equipped with the electrocardioelectrode in other positions and obtain electro-cardio signal, such as, the positions such as cervical region, shoulder, upper arm, forearm, such as, the neck that can pass through as item refining, necklace is worn structure and is arranged near cervical region and shoulder, also can pass through arm and wear structure or wrist is worn structure and is arranged on arm, quite convenient equally.Therefore, as long as the Electrocardiographic electrode setting position that can project out all belong to this utility model for the category of specification.
According to the conception of the another aspect of this utility model, this wear structure is embodied as a wrist to wear structure, therefore, wear structure by this wrist carried according to Wearable ECG checkout gear of the present utility model, and use and be arranged in a wrist of user, this Circuits System is then be placed in this wrist to wear in structure, and/or in the housing comprised further.
Wherein, as shown in Fig. 9 A1,9A2, this first electrode 10 be positioned at when this wrist wear structure be arranged in wrist time, on this device can because of wearing action with this wrist near contact skin one on the surface, as for 12, this second electrode be positioned on this device except this surface another on the surface, such as, can be the surface relative with this surface, or on the surface be adjacent, only should be noted it is the position that can not contact this wrist place limb skin.At this, this first electrode 10 also can be embodied as has two electrodes, as shown in Figure 9 B, and using one of them electrode as ground connection or reference electrode, to suppress common-mode noise, such as, from the noise of power supply, therefore, enforcement does not limit.
At this, wrist is selected to be as the main cause of the position arranging ECG detection device, because wrist wears form to user, just as worn wrist-watch, be familiar with and the occupation mode that need not relearn, directly wrist is worn structure and be incorporated into the contact that wrist can complete between the first electrode and skin, afterwards, when there being electrocardiogram under needs record at any time, the contact of other partial skins that only need carry out again beyond by this second electrode and this finger place limbs just can carry out electrocardiosignal extraction at once, operating process and action simple, naturally facilitate again.And wear structure by wrist and exert a force to wrist, the contact between this first electrode and skin need not exert a force and can realize by user, and muscle tone can be allowed to be down to minimum for the impact of electrocardiosignal.
So, when practical operation, as shown in Figure 9 C, as long as user utilizes hands to contact this second electrode, just can realize electrocardiosignal easily and extract loop, quite convenient.And except wear structure carrying except the form of housing, also can, as shown in Fig. 9 D1,9D2, circuit be placed in Wrist wearable type structure, and therefore, not restriction.
And, especially, according to the conception of the another aspect of this utility model, also can be further, as shown in Fig. 9 E-9F2, this first electrode 10 and this second electrode 12 are embodied as and wear structure 90 respectively by wrist and refer to wear structure 92 and realize the contact with skin, thus, wear structure only need be worn on finger and wrist by user respectively, namely the electrode configuration of measuring needed for electrocardiosignal has been completed, quite convenient, and, two contacts between electrode and skin are all realized by wear structure positive force, user need not exert a force and can realize the contact with electrode, add, if both hands all can be positioned in fixing plane when measuring by user, the electromyographic signal interference caused because of muscle tone can be made can be reduced to minimum, quite there is advantage.
In addition, in the embodiment shown by Fig. 9 E and Fig. 9 F1,9F2, also additionally further can wear structure not with on the surface of wrist contact skin at this wrist, one the 3rd electrode is set again, such as, be arranged at the surface 94 shown in Fig. 9 F1,9F2 or surface 95 on, with allow user do not use refer to wear structure when, still can be carried out the acquisition of electro-cardio signal by the first electrode 10 and the 3rd electrode, the selection that another uses is provided.
Moreover, further, also a connectivity port 14 can be comprised according to Wrist wearable type ECG detection device of the present utility model, as shown in figures 10a-10c, to be electrically connected The the 3rd electrode 16 by a connecting line, at this, 3rd electrode can be embodied as the function replacing this second electrode further, such as, can be embodied as this second electrode can the 3rd Electrode connection to during this connectivity port automatically by anergy, or, which electrode what also allow user decide in its sole discretion by a change-over switch will to start is, embodiment is unrestricted, in addition, 3rd electrode 16 also can be embodied as and be realized and contact skin by wear structure, such as, ear wears structure (as shown in Figure 10 B), finger wears structure (as illustrated in figure 10 c) or wrist wears structure etc.
Alternatively, 3rd electrode 16 also can be embodied as and be connected by the mode of adapter, as shown in Figure 10 D1,10D2, now, the first electrode 10 can be worn structure because wearing this wrist and contact the wrist of user, and the 3rd electrode 16 can be positioned at this and refer to wear among structure, in this case, owing to referring to that wearing structure is combined with the device in wrist by adapter, therefore, the measurement posture of quite stable can be realized, more contribute to the electrocardiosignal obtaining high-quality.
When such as being extended the 3rd electrode shown in Figure 10 B-10C by connecting line, compared to the second electrode being positioned at apparatus surface, device of the present utility model can provide more contact position to select, to obtain the electrocardiogram of different heart Angles Projections, for example, heart projecting angle when use the second electrode be by two handss (wear wrist wear structure wrist and contact the second electrode hand) and obtain time, using the 3rd electrode just can provide utilizes ear to wear form touch ear (such as, wear wrist wear the left hand of structure and wear the left ear that ear wears structure) to obtain the Electrocardiographic selection of different heart projection angles.
As previously mentioned, because the cardia producing pathological changes may be positioned at any cardiac position, such as, the inspection of myocardial infarction needs to watch in ecg wave form the ST drift whether occurring occurring because of myocardial necrosis, but when pathological changes generation position cannot be discovered under some angle, the electrocardiogram of different angles just has its necessity.
Therefore, device of the present utility model, by extending three electrode mode, allows user carry out except electrocardiosignal measurement except being positioned at second electrode on surface by contact, also can when there being demand, simply by the mode connecting an electrode again, and obtain more information about heart.
In addition, the 3rd electrode extended also further provides other advantages used.
In this utility model, the setting of the second electrode allows user can very simply and promptly obtaining electrocardiosignal by the mode of touching surface electrode whenever necessary, the 3rd electrode extended then provide that user obtains stabilization signal another select.Due to when use the 3rd electrode, it is made the 3rd electrode and user health part contact skin, therefore, the factor such as muscle tone, hand shake that the most easily can affect electrocardiosignal quality is got rid of, and then obtains the more stable and electrocardiosignal of high-quality.
In addition, relative to the hands of touching second electrode, the 3rd electrode extended by connecting line as shown in Figure 10 B-10C also allows user can select the measuring position that electrocardiosignal is stronger, such as, the position that distance heart is nearer, diminish to allow the impact of interfering signal, such as, the electromyographic signal of formed objects can be excluded when electrocardiosignal is stronger, but just when electrocardiosignal is fainter distinguishes because making with electrocardiosignal and produce and judge by accident possibly, so, user is just by being arranged at the position that can obtain compared with the heart tonifying signal of telecommunication by the 3rd electrode, and then the correctness of raw analysis result.
So, according to Wrist wearable type ECG detection device of the present utility model, there are two kinds of operator schemes, first operator scheme and the second operator scheme, in this first operator scheme, form the first electrocardiosignal together by this first electrode and this second electrode and extract loop, to obtain the first electrocardiogram, and in this second operator scheme, this first electrode and the 3rd electrode form the second electrocardiosignal together and extract loop, and then obtain the second electrocardiogram, and by alternative operator scheme design like this, even if face different operating environments and use habit, all can obtain and stablize and high-quality electrocardiosignal.
And except Wrist wearable type ECG detection device, similarly, above-mentioned also can being embodied as according to finger-worn type ECG detection device of the present utility model and ear-wearing type ECG detection device has a connectivity port, to connect one the 3rd electrode, replace this second electrode.
For example, as shown in Figure 11 A, finger-worn type ECG detection device connects a finger-worn type the 3rd electrode by connecting line, and as Figure 11 B, ear-wearing type ECG detection device also connects a finger-worn type the 3rd electrode by connecting line, these two kinds of situations all allow the operator scheme that hands originally need be utilized to contact electrode can be provided the finger of positive force wear structure replace, thus, because of hand comes in contact, issuable instability factor just can be excluded, and contributes to obtaining more stable signal; In addition, as shown in Figure 11 C, finger-worn type ECG detection device also can connect an ear-wearing type the 3rd electrode, except providing the metering system that need not exert a force, also obtains and contacts the different heart projecting angle electrocardiogram of electrode with both hands.Therefore, not restriction.
Again further, also can be embodied as according to Wearable ECG checkout gear of the present utility model, the first electrocardiogram can be obtained by the first electrode and the second electrode simultaneously, and obtain the second electrocardiogram by the first electrode and the 3rd electrode, as shown in Figure 12 A and Figure 12 B, that is, this first electrode is when measuring, form ECG detecting loop with this second electrode and with the 3rd electrode simultaneously, thus, user just can select different operator schemes according to different demands, to obtain the heart information closest to self-demand.
Moreover, according to this utility model conception on the one hand again, this wear structure is embodied as one and wears structure, therefore, worn structure according to Wearable ECG checkout gear of the present utility model carried by this, and use the head being arranged at user, this Circuits System is then be placed in this to wear in structure, and/or is placed in the housing that comprises in addition.
As shown in figure 13, this the first electrode position when this wear structure be arranged at head time, this device can contact with skin of head because of wearing action one on the surface, as for 12, this second electrode be position on the apparatus except this surface another on the surface, to contact upper limb (such as, finger, arm), the skin of the position such as cervical region, shoulder, and then reach electro-cardio signal acquisition loop.At this, be with should be noted, the setting position of this second electrode can have various selection, for example, can be situated on relative surface, this surface of wearing structure with this or the surface be adjacent, touch for upper limb, or refer to wear structure, wrist wears structure or arm wears structure and contact the skin of upper limb through one; Or, alternatively, also can connect an ear that can be fixed on ear and wear structure, and this second electrode is arranged at the exposed surface that this ear wears structure, utilize upper limb to contact for user; Such as, or alternatively, also can pass through connecting line and this second electrode extended to the position such as cervical region or shoulder, the neck through such as necklace, item refining wears structure, equally also can obtain electro-cardio signal.Therefore, various possibility can be had, not restriction.
At this, this wears structure also can be embodied as various forms, such as, belt body, head-shield (headgear), or the rigid head frame of tool guiding mechanism, or glasses form etc., focus on the contact can reaching electrode and skin, therefore, not restriction.
Head and ear have similar characteristic, be not easy generation can cause interference electromyographic signal to electrocardiosignal, therefore, the position being applicable to arranging electrocardioelectrode equally, and, by wearing structure, also electrode for encephalograms can be set further, to obtain EEG signals, for example, only at least two electrode for encephalograms need be set in the inner side of wearing structure, or when being combined with ear and wearing structure, set up an electrode for encephalograms separately wearing the inner side that structure wears structure with gill, with the EEG signals sample point on contact head, such as, common sample point comprises Fp1, Fp2, O1, O2, A1, A2 etc., or any position defined according to 10-20 system, just can when increasing burden hardly, there is provided user more measuring ability, quite there is advantage.
And, be arranged at the electrocardioelectrode worn in order to contact head skin in structure, that is, first electrode, also can share as electrode for encephalograms further, and form electro-cardio signal acquisition circuitry with this second electrode, and form brain electricity acquisition circuitry with another electrode for encephalograms.
Or, alternatively, the mode shared also can be embodied as, be used for obtaining electro-cardio signal and brain electric signal by two electrodes simultaneously, that is, electro-cardio signal and brain electric signal obtain through same physiological signal acquisition circuitry, at this, the reason that can perform like this is, electro-cardio signal is much larger than brain electric signal, wherein, electro-cardio signal about drops on the scope of millivolt (mV), and EEG signals then drops on the scope of microvolt (μ V), therefore, even if enter the same input of physiological signal acquisition circuitry, both still can be distinguished from each other.
When implementing, for example, the electrode of a contact head can be utilized, in cooperation another can simultaneously contact head and hand electrode and reach obtaining of electro-cardio signal and brain electric signal, wherein, the electrode of this simultaneously contact head and hand, for modal metal electrode film, two electrode slices that can be embodied as contact hand and head are electrically connected to each other, two parts that also can be embodied as an electrode slice contact hand and head respectively, such as, when be arranged at wear in structure time, in the skin of interior side contacts head and the skin of outside hand, therefore, form of implementation is not limited.
Accordingly, electrode for encephalograms is applicable to the ear be arranged at as Fig. 5-6 and Fig. 8 too and wears in structure.First, ear and ear near zone have the position that cerebral cortex activity can be detected, such as, temporal lobe district (temporallobe), moreover, in brain electro-detection field, ear due to structure and position be all separated with head, be not subject to the impact of brain activity, therefore be considered to be one of optimum position that reference electrode is set always, so, being incorporated into ear with reference to electrode wears in structure and ear contacts, originally brain electro-detection time institute is common, therefore, according to ear-wearing type ECG detection device of the present utility model being also quite suitable for combination, electrode for encephalograms is set, to obtain brain electric signal, and, also be applicable to same the mode adopting shared electrode, that is, first electrode is embodied as electrode for encephalograms simultaneously.
Further, in the embodiment of Fig. 5 A-Fig. 6 and Fig. 8, wear except in structure except two electrode for encephalograms are all arranged at ear, also can connect in addition and wear structure, so that an electrode for encephalograms is arranged on wherein, thus, just can pass through to be arranged at respectively and wear structure and wear structural electrode for encephalograms with gill and obtain brain electric signal, and wear electrocardioelectrode in structure and coordinate through being arranged at ear and be arranged on ear and wear electrocardioelectrode (Fig. 5 A-Fig. 6) on structure exposed surface, or being arranged on finger wears the electrocardioelectrode of structural electrocardioelectrode (Fig. 8) and obtains electro-cardio signal, and then provide various possible enforcement to select.
When reality uses, according to ECG detection device of the present utility model owing to adopting the design of wearing form, because herein is provided the probability obtaining electrocardiosignal during dressing easily continuously, also therefore provide user more facilitating functions.
First, due to adopt dress form user can be allowed free of a burden be worn on it, therefore, be quite applicable to wear use in daily life, for example, device can be worn on ear, on finger or in wrist by user in daily life, and at any time whenever necessary, such as, when thinking that heart is uncomfortable, start ECG signal sampling in real time, or carry out Electrocardiography termly every day, effectively grasp the heart change of self.
Especially, ARR generation is often without early warning, therefore, by being worn on ECG detection device with it like this, electrocardiogram when electrocardiogram when just can note down lower generation arrhythmia in real time or user sensation irregular heartbeats, to judge whether foundation when suffering from arrhythmia as doctor.
For example, be no matter adopt refer to wear, ECG detection device that Er Dai or wrist wear form, user all when feeling under the weather or can be wanted to record electrocardiogram, electrocardiogram is obtained in real time by the mode of hand comes in contact second electrode, as Fig. 2 A, Fig. 5 B, and shown in Fig. 9 C; Alternatively, when to be arranged at it or to use three electrode situation by wear structure according to the second electrode, because two electrodes obtaining electrocardiosignal complete contact all, therefore, user only need start electrocardiosignal and measure, such as, by started by press key, just electrocardiogram can be recorded in real time.No matter which kind of situation is all quite simple and convenient in use.
At this, the electrocardiogram that automatically can record next set time after electrocardio measurement is activated can be set as according to device of the present utility model, such as, 30 seconds or 1 minute, with allow user can heart does not feel well under real time record like a cork time, such as, there is electrocardiogram during arrhythmia.
In addition, user also can select the lower continuous print electrocardiogram of long-time record, and especially when two electrodes are all arranged at it by wear structure time, and by analyzing the electrocardiogram that long-time continuous obtains, user can obtain more information.
For example, the information of continuous heart rate sequence can be obtained according to continuous ECG, analyze to carry out HRV (HeartRateVariability, heart rate variability rate).It is observe the movable topmost method of autonomic nerve that HRV analyzes, and analyzes produced analysis result, the situation of understanding autonomic nerve activity that can be detailed by HRV, such as, orthosympathetic activity, parasympathetic activity, the equilibrium condition of autonomic nerve, and the active size etc. of autonomic nerve entirety, and existing more and more study display, numerous disease, such as, headache, intestines and stomach discomfort, hypertension, insomnia, depression etc. may be all because vegetative dystonie caused.So, just can be learnt in daily work and rest by long-time continuous HRV analysis result, the change situation of autonomic nerve activity, and then inquire into which behavior or emotion in daily life and whether cause vegetative dystonie, and whether above-mentioned disease is led because of in vegetative dystonie etc.
And, owing to being adopt the form of dressing according to device of the present utility model, therefore, by this information provider unit, also the result that real-time HRV analyzes can be provided and give user, therefore, user just can learn which behavior or emotion may cause autonomic nerve unbalance in real time, and further, by the design that this utility model is such, user also can carry out mental regulation in real time, such as, body and mind relaxing, and learn therefore whether autonomic nerve return to the state comparatively coordinated.
In addition, when in the sleep period chien shih used time, by carrying out HRV analysis to continuous ECG between sleep period, also can understand the physiological change between sleep period, such as, can sleep cycle be judged, sleep quality etc. can be understood, suitable tool convenience.
At this, be, after obtaining electrocardiosignal, can be embodied as according to device of the present utility model and electrocardiosignal is first stored with should be noted, after end to be measured, then export and be further processed, such as, export computer apparatus to and carry out storing and analysis etc.; And/or, because device of the present utility model has information provider unit, therefore also in real time relevant information or analysis result can be provided and give user, such as, average heart rate, HRV analysis result etc., such as, and/or this information provider unit also can be embodied as and recorded electrocardiosignal and/or data are transferred to an external device (ED) in real time, mobile phone, panel computer etc., and shown in real time by this external device (ED) and/or analyze, therefore, not restriction.
Moreover, the approach allowing user can carry out with oneself respiratory training is also provide for according to Wearable ECG checkout gear of the present utility model.By being worn on form with it, continuous electrocardiosignal can be obtained according to device of the present utility model, and obtain the time series of eartbeat interval, that is, heart rate sequence, and by analyzing this heart rate sequence, just can obtain relevant arrhythmia (RespiratorySinusArrhythmia, RSA) information, so-called RSA refers to, when heart rate is by autonomic nerve control, breathe and make heart beating occur the phenomenon of change because having an impact to autonomic nervous system, generally speaking, intake period, can make to palpitate quickly, heart beating is then made to slow down between respiratory period, therefore learn the changing pattern of breathing and the activity situation of autonomic nerve by observing RSA.
Separately, because breathing is that a kind of control by autonomic nerve again can by realizing the physiological activity that affect, therefore, autonomic nerve is affected by adjusting breathing consciously, to reach the effect of body and mind relaxing, wherein, according to research display, breathing rate (respirationrate), tidal volume and during exhaling/intake period ratio is all the factor of the sympathetic and parasympathetic nervous activity of impact, wherein, speed is slack-off reduces orthosympathetic activity, speed accelerates, and sympathetic activity can be made to increase, for example, the breathing rate of general adult about drops in the scope of 10-18 time per minute, when the speed of breathing can be reduced to the scope of 5-8 time per minute, can contribute to increasing parasympathetic nervous active, in addition, when exhale during/intake period ratio increase time, that is, time during there is expiration longer for intake period, parasympathetic activity can obtain lifting equally.
So, generally speaking, namely respiratory training is contribute to a respiratory daoyin of the breathing pattern of body and mind relaxing by providing user to have and carry out, such as, respiratory daoyin can provide the breathing rate dropping on 5-8 time per minute that can reduce sympathetic activity, and/or can under general breathing prerequisite, during the expiration increased, breathing rate and/or during increasing expiration is reduced to guide user, and then it is active to increase parasympathetic nervous, suppress sympathetic nerve, and allow human body can remove from tense situation, recover to loosen.
And, because vegetative dystonie is also one of ARR important origin cause of formation, therefore, under Electrocardiographic situation when wishing that arrhythmia occurs under real time record in one of the object of the user using this device, this utility model device provides respiratory daoyin training function, changes the mode of autonomic nerve balance, will contribute to improving arrhythmia symptom to allow user pass through control breathing, both complement each other, and have more meaning.
When utilization carries out respiratory training according to Wearable ECG checkout gear of the present utility model, with it device only need be worn on by user, and maintain two contacts between electrode and skin, and during carrying out respiratory training, this information provider unit then gives user in order to be provided by respiratory daoyin signal, follow adjustment to allow user to breathe, in addition, this information provider unit also can provide about the physiological status change of user during respiratory training, such as, sympathetic nerve and negative orthosympathetic activity change, the change of heart rate, and the change etc. of actual breathing pattern, to carry out the reference of respiratory training as user.
At this, because the time performing respiratory training is longer, therefore, be preferably, user can select two electrodes to be all arranged at form with it by wear structure, such as, utilizes the second electrode arranged by wear structure, or utilize the 3rd electrode to coordinate the first electrode to carry out electrocardiosignal extraction, and carry out respiratory training in mode more easily.
In addition, this respiratory daoyin signal can also be the dynamic steering signal carried out according to the respiratory variations pattern acquired by heart rate sequence as adjustment, namely, by the breath state of user obtained in real time, be conducive in the speed range of body and mind relaxing to learn why and/or whether breathing rate drops on, and dynamic conditioning steering signal according to this, and allow user can reach the effect of respiratory daoyin training in the most comfortable mode.
Or, reaction (RelaxationResponse) is loosened because the amplitude strengthening RSA contributes to triggering, remove the pressure of accumulation, and reach the effect of raising parasympathetic nervous/sympathetic activity ratio, therefore, by observing the changes in heart rate pattern of user, and when heart rate starts to accelerate, inform that user can start air-breathing by guiding, and when heart rate starts to slow down, inform that user can start to feel elated and exultant by guiding, to reach the effect increasing RSA amplitude, also reach the object of body and mind relaxing.
Further, also learn that whether breathing is harmonious and synchronous with heart rate by carrying out the result of frequency-domain analysis to heart rate sequence, between breathing and heart rate, harmonious and synchronicity then represents heart beat rhythm that is more orderly and that coordinate preferably, namely, human body be in compare loosen, stable state, therefore, when user obtains relevant information when training, the physiological status of self is just changed by consciousness.
In addition, when can obtain EEG signals when coordinating upper electrode for encephalograms, observable heart rate, breathes and synchronicity (synchronization) between EEG signals, and understands the physiological status of user.Because, according to research display, exhale and can cause the fluctuation of Ink vessel transfusing blood volume with air-breathing, and this fluctuation also can arrive brain along with blood flow, and then cause E.E.G in low frequency section, such as, lower than 0.5 hertz, fluctuation, therefore, also can pass through and observe E.E.G and learn breathing pattern, moreover, because the SA node of heart and vascular system are also by the regulation and control of autonomic nervous system, and, the change of heart rate and blood pressure also can be fed to back brain through pressure receiver system (baroreceptorsystem) by autonomic nervous system, and then affect function and the running of brain, such as, affect cerebral cortex, and can be recorded by EEG, therefore, the relation affected each other is there is between three, and synchronicity good between three can represent human body is in the state comparatively loosened, quite useful information.
For example, this information provider unit is while providing this respiratory daoyin signal, the information of relevant heart rate also can be provided in real time, and/or the information of the synchronicity of the related breathing being calculated by frequency spectrum and obtain and heart rate, therefore, user just can learn the impact of breathing and adjusting and causing for autonomic nerve in real time, such as, whether parasympathetic activity obtains lifting, or whether orthosympathetic activity reduces, thus, the biofeedback program of carrying out with respiratory daoyin signal of can making concessions has more efficiency.
In addition, also can learn the effect of respiratory training by user further by the analysis result of HRV, such as, HRV can be performed respectively analyze in the front and back of carrying out respiratory training, and learn the impact that respiratory training brings for autonomic nerve, even, also can be embodied as real-time HRV to analyze, and allow user learn the activity situation of autonomic nerve in real time by this information provider unit, and allow user understand the physiological situation of self in real time in the mode of similar biofeedback, contribute to the effect realizing body and mind relaxing further.
Because HRV analysis analyzes heart rate sequence in a period of time, therefore, the carrying out that real-time HRV analyzes is implemented by the concept of traveling time pane (MovingWindow), that is, first determine one computation time section, such as, 1 minute or 2 minutes, afterwards, by the continuous mode that this time section is passed backward, such as, within every 5 seconds, calculate once, just obtain HRV analysis result sustainably, such as, within every 5 seconds, obtain a HRV analysis result, thus the object that real-time HRV analysis result is provided is realized, in addition, also the concept of weighted calculation (weighting) can be adopted, moderately increase comparatively close to the calculated specific gravity of the physiological signal of analysis time, real-time physiological situation is more pressed close to allow analysis result.
This information provider unit can have various selection when providing this respiratory daoyin signal, such as, can adopt vision, the mode of audition and/or sense of touch guides, not restriction.The selection of visual guidance includes, but not limited to graphic change, text importing, luminosity changes, and/or cresset change etc., be all suitable mode, for example, the pattern that meets respiratory variations pattern can be utilized on the display element and guide user and carry out air-breathing and feel elated and exultant; Or represent air-breathing by the number change of LED and feel elated and exultant; Or word can be utilized directly to inform, and user carries out air-breathing and feels elated and exultant.
In addition, when adopting the mode of audition guiding, selecting then to include, but not limited to sound variation and voice, for example, air-breathing can be represented and change of feeling elated and exultant by the power of sound; Or represent air-breathing by different sound kinds and feel elated and exultant, and allowing user follow, such as, tweedle, sound of sea wave, different music track etc.; Or also can be informed user this carries out air-breathing or feels elated and exultant by voice, such as, when just starting to carry out respiratory daoyin training, " air-breathing " and " feeling elated and exultant " voice by meeting respiratory variations pattern indicate and guide the breathing pattern of user, and when detecting that the breathing of user has met the changing pattern for reaching, namely inform that user " continues to maintain present compressing speed ", and stop the voice instruction that " air-breathing " " feels elated and exultant ".Therefore, various selection can be had, can change, not restriction according to the demand of actual enforcement.
And when being embodied as according to device of the present utility model the situation be combined with earphone, above-mentioned audition guides will seem more natural, and, because sound and/or voice directly enter ear via earphone, people at one's side can not be bothered completely, therefore also further provide disguise, the carrying out of respiratory training can not be limited by time place, such as, when riding public transportation means, also can respiratory training be carried out, more convenient.
