Description

Neck wears formula ECG detection device

Technical field

The present invention relates to a kind of neck and wear formula ECG detection device, further, the present invention also relates to and a kind ofly has the stabilized electrodes way of contact and the neck that can obtain clear and stable electrocardiosignal wears formula ECG detection device.

Background technology

Known, ECG detection device is the main path for checking various heart disease, such as, whether has arrhythmia, because of diseases such as myocardial hypertrophy, myocardial infarction or the angina pectoriss caused by hypertension or valvular heart disease.

When when people experience heart discomfort, the hospital that arrives checks, many employings be traditional ECG detection device, such as, twelve-lead electrocardiogram detects, can be more detailed detect various cardiac problems, if but the source of heart discomfort is sporadic symptom, such as, arrhythmia, heart condition during morbidity then probably cannot be recorded between detection period, therefore, in response to this kind of sporadic symptom, how can adopt and to wear the mode that Huo Teshi (Holter) electrocardiograph carries out long-time detection, such as, wore for the 24 little times up to a couple of days, wish the electrocardiogram recorded by this way when there is symptom, and it is similar with Huo Teshi electrocardiograph, cardiac electrical event recorder (ECG event recorder) is also the mode adopting extended wear, but be differently, it allows user decide the time of record in its sole discretion, such as, time heart is felt ill, and record electrocardiogram through the mode of pushbutton enable, such as, device does not carry out record usually, but the electrocardiogram of before and after compressing time each 30 seconds is just recorded when user presses the button.And except being used for recording except sporadic symptom, Huo Teshi electrocardiograph is also usually used in monitoring of cardiac operation or the heart situation after taking medicine, to confirm therapeutic effect.

No matter be Huo Teshi electrocardiograph or cardiac electrical event recorder, its set-up mode all must be pasted multiple in order to obtain Electrocardiographic electrode with it, and be connected to a device through connecting line, therefore, user must paste electrode during measuring always and device is worn in it, quite inconvenience, also easily skin discomfort is produced because pasting electrode for a long time, these are all the reasons allowing user step back, add, even if sometimes also there will be after wearing detection for a long time, but any electrocardiogram for analyzing sporadic symptom is not recorded because not having to fall ill.And, such detection, the assistance that must be transmitted through health care professional just can complete setting, such as, pasting of electrode must be provided with in hospital, further, normally after completing measurement for a long time, then the electrocardiogram got off by doctor's Download History is analyzed, what is wrong to need at least just to know heart after a couple of days, so not only complexity is high, also lack real-time.

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 sticks in it through adopting and solve and by device extended wear in puzzlement with it, and must simplify complexity when detecting.As US7149571 and US7197351 disclose, Handheld electrocardio detecting device is provided with dry-type electrode on the surface of device, ECG detecting can be carried out through the mode contacting hands and/or body surface at any time when there being demand, therefore, no longer be limited to wear and paste in time with it and electrode, therefore for longer periods can be 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, by the time need not return to hospital and examine, 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, intelligent mobile phone universal, what occur in recent years is the ECG detection device combined with mobile phone, as US8615290 disclose, itself and Handheld electrocardio detecting device are similar, be adopt dry-type electrode equally, the operation-interface that difference is only to be through mobile phone carries out the manipulation of device, and such mode allows the user of monitoring of cardiac demand can reduce the quantity of the device carried with.

But, the greatest problem that above-mentioned portable Handheld electrocardio detecting device faces is caused because utilize hands to carry out operation also.When adopting contact both hands form, as shown in Figure 1, first problems faced is exactly that signal is more weak, due to both hands and heart distant, add electrocardiosignal originally just little, after fainter, be very easy to the impact being subject to environment noise, and allow the carrying out analyzed become difficulty, another problem is then that stable operation degree is low, 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 baseline drift, the situation of the impact analysis such as waveform distortions, and, when user wishes that hand remains stable and muscular tone, or during specially firmly to guarantee with electrode Contact, also the electromyographic signal of the signal analysis that has an impact because exerting oneself is easy to.

When adopting the mode in grip device another side contact chest on the other hand, as shown in Figure 2, compared to bimanualness, can be comparatively stable, acquired signal is also stronger, just, such mode of operation has a maximum scruple, clothes must be raised exactly just can measure to contact chest, naturally limit operable occasion, in addition, thoracic cavity is because breathing the fluctuating produced, the electrode in contact chest still can be caused to produce relative movement with between the electrode contacting hands, measured electrocardiogram can be affected equally.

In addition, Handheld electrocardio detecting device operates owing to must be gripped by hands, under the demand meeting ergonomics, adds and needs to show result, cannot be too small in size, carries and is 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.

Moreover, there is another kind to utilize neck mode of hanging to be worn on heart rate monitoring unit with it, such as, US8668643, US20130345578, US20080287768, and US20070106145 those disclosed herein.Although such device is easy to carry, but be the mode that electrode touches health naturally due to what adopt, compared to aforementioned adherent electrode or hand to modes of operation such as electrode surface forces, lack fixing strength, therefore the contact between electrode and skin is very unstable, also therefore clear and stable electrocardiogram cannot be obtained, therefore and be not suitable for for judging whether heart occurs exception, such as, whether there is the symptom such as arrhythmia, myocardial infarction, add the particular arrangement mode that electrode is arranged at cervical region by it, also causing using has many restrictions.

Therefore, really need a kind of ECG detection device that can solve above-mentioned shortcoming, while user can be used more easily, also can the impact of various uncertain factors during operation is down to minimum.

Detailed description of the invention

Because allow user can Electrocardiographic object under real time record, device of the present invention is embodied as wearing form, and in many modes that ECG detection device can be arranged at it, the present invention have selected neck and wears, wearing mode as shown in Figure 4, main reason is as follows.

First, through the form that neck is hung, device can be placed in trunk front naturally, as below clavicle, front, the position such as abdominal part front, because as is known in the art, trunk is the region that electrocardiosignal is the strongest, and therefore, first such setting ensure that acquired signal has enough intensity.

Moreover compared to the pectoral girdle form that device can be arranged at front equally, it is little many that neck wears the constraint sense that form brings user, thus can provide more comfortable use experience.

In addition, neck is worn form and is also allowed device can naturally position be between clothes and trunk, and the action of electrode contact trunk does not need to raise clothes and just can reach, and eliminates the restriction of use occasion, allow user no longer because must clothing be lifted step back, or condescend to take this post in the more weak both hands number of the winning the confidence metering system of signal.

In addition, the present invention adopts dry-type electrode, and user can be used at any time, need not worry the problem that electrode is arranged, and saves and must use the trouble of conductive paste and eliminate the doubt that user may be caused to occur the uncomfortable phenomenon of skin.

Therefore, wear mode through employing neck, according to the various shortcomings overcoming aforesaid known technology of the present invention, such as, need to paste electrode, may cause that skin is uncomfortable, signal intensity not, lack real-time, clothing need be lifted carry out the problem such as measuring.

And also due to adopt the form worn of neck allow user can ground free of a burden worn for long periods in it, add and naturally, easily can obtain the enough electrocardiosignaies of intensity at any time, therefore, be quite applicable to being applied to nurse field at home, for example, device can be worn in cervical region 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.

In addition, neck according to the present invention is worn when formula ECG detection device is also quite adapted at motion and is used, for example, user can have in motor process can not feel burden according to device of the present invention, and at the volley between time of having a rest directly be measured and know the impact that heart is caused of moving, such as, whether reach enough exercise intensitys (whether heart beating reaches re-set target), or whether heart there is exception etc., especially motion be arrhythmia send out the time well, therefore, electrocardiogram when just can there is arrhythmia under very real-time record through device of the present invention.

Refer to Fig. 3, its display neck according to the present invention wears the configured in one piece schematic diagram of formula ECG detection device.As shown in the figure, neck according to the present invention wears formula ECG detection device 10 from finding out that having a housing 12, depends on assembly 14 in appearance, and at least two electrodes 16, wherein, this depends on assembly 14 and is embodied as and combines with this housing 12, and can adhere to the cervical region of user, with the front making this housing 12 be positioned at user trunk, such as, below clavicle, front, the position such as abdominal part front, as shown in Figure 4, electrode 16 is then the surface being positioned at housing 12.

In a preferred embodiment, electrode according to the present invention is embodied as position on the same surface of this housing, as on the first surface 122 of Fig. 3, that is, when housing is arranged at trunk front through this depends on assembly, towards trunk this on the surface, as shown in Figure 4, even if be covered in clothes, two contacts between electrode and skin also can be reached easily, therefore do not need to lift clothing and also can detect.And so the basis of embodiment is just, through the form that neck is worn, be arranged on the position around heart according to the housing of device of the present invention, the position that electrocardiosignal intensity is enough, the restriction when arranging electrode position is little, and such as, distance can be very short.

In the present invention, electrode is arranged on housing, but not as on the belt body of known technology, and except the stable contact of belt body top electrode is not easily reached, chief reason is:

First, as previously mentioned, near heart, namely body, be heart signal sample position the most clearly, and because two electrodes are very close each other, circuit loop is short, all kinds of noise jamming electrocardio can be avoided to measure, particularly for common-mode noise, as 50Hz/60Hz can be got rid of easily.

Moreover, when electrode is all positioned on housing, user can easily through mobile shell with regard to traveling electrode position, and then change the relative position of electrode and heart, just can obtain the electrocardiogram of various different angles.

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 possibility position of generation pathological changes is 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 the electrocardiogram through different angles just likely to check to draw, therefore, obtain the electrocardiogram of different angles for judging that heart disease is very helpful.

So, when electrode is all positioned on housing, electrode position can move through mobile shell very simply, add housing position in body front, very near with heart distance, even if short-range movement also can obtain the very large decentraction electrograph of angle difference, even if even just roll-shell, such as, rectangular housing 90-degree rotation, as shown in figs. 5 a-b, also same effect can be had, therefore, through such setting, even a very simple neck wears formula ECG detection device, the electrocardiogram of multi-angle can be provided equally for user, and more information about heart state is provided.

So, for device of the present invention, exactly because electrode is arranged on housing, just can overcome the shortcoming that known neck wears formula ECG detection device, and then when not losing signal intensity, provide user most convenient and use experience free of a burden simultaneously.

In addition, through there is the housing of certain degree of hardness to arrange electrode, also allow the contact stabilization between electrode and skin obtain promote, add, two electrode positions are on same housing face, and relative position is between the two fixed, therefore, even if occur during measurement as body actions such as breathings, still good contact stabilization degree effectively can be maintained.

As mentioned above, what neck according to the present invention wore that formula ECG detection device adopts is dry-type electrode, and therefore, the material of electrode can employing stainless steel as is well known, and is fixed on surface of shell; And alternatively, electrode also can be embodied as, for example, the local conductive coating of surface of shell, or housing itself is conductive material, utilizes coating isolation material and construction goes out electrode position, therefore, can have various probability, not restriction.

In addition, because the present invention adopts neck to wear form, and device is hidden in clothes, therefore, also can consider to use non-conductive electrode, such as, the electrode form of condenser type, vicarious, electromagnetic type etc. can be adopted, to increase ease of use further, such as, even if by this through the medicated clothing also desirable electrocardiosignal obtaining hand, the configuration restriction of electrode is also allowed to reduce, there to be more change in response to operating habit.And when adopting this kind of non-conductive electrode, the housing of non-conductive material also can be utilized as electrode, and such as, a part for capacitive electrode.

At this, this form depending on that assembly the most easily implements is the belt body around cervical region, such as, and necklace or necklace etc., but it is not limited, as long as can pass through cervical region and arrange the mode of housing, all belong to the scope that the present invention is contained, and, its material used also can change according to actual demand, such as, can be the belt body that the various materials such as fabric, metal, rubber are made, not restriction.

Moreover, further, also can pass through and depend on assembly and help housing to carry out orientation, as shown in figs. 5 a-b, by the combination between design add-on assemble and housing, the surface of shell with electrode can be allowed more naturally towards trunk, and then to guarantee between electrode with skin correct contacts.

Then, refer to Fig. 6, the electrocardiosignal that its display neck according to the present invention wears formula ECG detection device extracts circuit, comprise an analogy signal processing unit 22, one processing unit 24, one transport module 26, and a battery 28, wherein, this analogy signal processing unit 22 is in order to receive the electrocardiosignal extracted through electrode 16, this processing unit 24 is as the control centre of whole ECG detection device, and can extract electrocardiosignal be processed, this transport module 26 is in order to carry out external transmission, this battery 28 is then electric power required when providing operation ECG detection device.

At this, this electrocardiosignal extraction circuit can be embodied as and be placed in this housing 12, or, also can be embodied as and be scattered in housing 12 and depend in assembly 14, or be separately set in and depend in assembly 14, not restriction, can change according to actual enforcement situation, for example, this depends on assembly except providing support except the function of housing, also can be embodied as and have bearing function, such as, this depends on assembly can be embodied as form as tubulose, so that circuit is placed in wherein, at this, further, this depends on the space that assembly also can be embodied as its accommodating circuit and communicates with housing; Or the quantity of this housing also can be embodied as more than one, and with accommodating more circuit, each surface of shell then all can have electrode, or only partial shell has electrode, such as, housing also only can arrange starting switch, etc., therefore, not restriction.

When user is when using according to device of the present invention, as shown in Figure 4, only need be fixed on cervical region by depending on assembly 14, device just can be placed on trunk front naturally, below clavicle, before breast, abdominal part front etc., afterwards, only need determine that the surface with electrode is towards trunk, thus, when there being needs to detect, just can hands be utilized like a cork to exert a force to housing, and make the surface of shell contact with electrode to skin, and start a special time, such as, 30 seconds, 1 minute, ECG signal sampling, or the time span that will detect is determined according to self-demand.

At this, be with should be noted that, generally speaking, Handheld electrocardio detecting device is many can give tacit consent to a Measuring Time, such as, 30 seconds or 1 minute, and automatically stop after time is up, except being to consider the persistent period of heart bursty state, also be to allow user need not maintain measurement posture excessively of a specified duration, more unstable situation is there is to avoid operation by human hand, but, device of the present invention is owing to being the form adopting neck to wear, and the hand factors of instability are down to minimum, therefore, user can be allowed to determine the time span of every secondary measurement according to actual demand, for example, when device predetermined 30 seconds Measuring Time terminate and sound remind time, user is not still let go by Continued depression electrode and allows measurement continue, all can completely go on record to allow various heart situation.

Also be with should be noted that, in order to what exert a force to housing, being not limited to is which position of hands, such as, can be finger, palm (palm of the hand or the back of the hand), wrist, arm etc., as long as user feels hand position easily, all detection can be completed, and also do not limit and use left hand or the right hand, user can freely detect according to personal habits.

Due to the contact between electrode and skin, what be dependent on is between the housing between hands and skin that exerts a force, therefore, what housing needs energy was correct and suitable conducts to electrode and skin by force, therefore is preferably, and the surface of shell in order to contact skin is embodied as the structure having and promote electrode contact stability, for example, when depending on assembly and housing being arranged at front, this surface can be embodied as has cambered surface, to meet the curve of chest; Or if depend on assembly when housing being arranged at abdominal part front, then this surface can be embodied as plane; Or if depend on assembly when being arranged at below clavicle by housing, then this surface can be embodied as curved surface or plane.In addition, especially, in a preferred embodiment, the housing parts arranging electrode can be embodied as projecting surface of shell, as shown in Figure 7, to allow force more concentrate on electrode contact, contact not only can be allowed more easily to reach, also can increase degree of stability.Therefore, not restriction.

Moreover owing to adopting neck to hang form, therefore, the size of housing is unsuitable excessive, excessive to avoid user cervical region to bear, and at vpg connection, specifically do not limit equally, such as, can be rectangle, square, circle or irregular shape, visual actual demand and changing.

In addition, the material of housing is also the key factor affecting electrode contact, and hand force can be conveyed to electrode by its needs, and to guarantee between electrode with skin stable contacts, therefore, the material that housing uses can have certain hardness, to guarantee the correct reception and registration of strength, such as, plastics, in addition, also can be embodied as and there is flexible material, such as, rubber, with the docile degree increased and between skin, therefore, material can have different selections equally, can actual demand and changing.

In a preferred embodiment, this housing also can be embodied as and is made up of two kinds of materials, as shown in Figure 8, that is, towards skin, the Part I housing 32 being used for carrying electrode adopts has flexible material, to allow this surface when contact skin, naturally deformation can be produced along with the fluctuating of contact skin area, make more docile between the two, also allow the contact of electrode and skin more stable, and the Part II housing 34 except this surface, just can use harder material, to reach the effect effectively passing on pressing strength, thus, the position no matter housing is set up why, contact between electrode and skin all can be unaffected.

Between detection period, except carrying out the extraction of electrocardiosignal, neck according to the present invention wears formula ECG detection device also can possess the function providing user to be relevant to the information between detection period.For example, an information providing module can be comprised, to provide user to be relevant to the information of signal using situation and/or extract, wherein according to device of the present invention, the mode that information provides comprises, but be not limited to, screen display, sound variation, vibration change, and visible change, such as, the mode such as color, brightness flop of luminescence component.

And the content of the data provided also can have various possibility, for example, during when user pressing housing for starting to measure, device can utilize sound notification user detection to start, and at the end of predetermined detection time, notify that user can terminate push action; Or, the in poor shape or signal quality of the current electrode contact of user can be reminded when starting to detect not good, allowing user adjust force size or the position of housing; Or, can remind between detection period or notify what situation user there occurs, such as, sound can being utilized to show heart beating change, as utilized the sound the same with palmic rate, or using sound notification heart state, as long and minor represent different states.In addition, further, upon completion of the assays, user result can be provided.Therefore, the mode that information provides and content neither restricted, as long as can allow definitely user obtain understand.
