Description

Neck wears formula ECG detection device

The present invention is：On 04 17th, 2014；Application No. is：201410156219.0；It is entitled：Neck Wear the divisional application of the patent application of formula ECG detection device.

Technical field

The present invention relates to a kind of necks to wear formula ECG detection device, is further, the present invention is also related to a kind of with steady The fixed electrode way of contact simultaneously can obtain the neck of electrocardiosignal that is clear and stablizing and wear formula ECG detection device.

Background technology

It is known that ECG detection device is the main path for checking various heart diseases, such as, if it intentionally restrains not The illnesss such as myocardial hypertrophy, myocardial infarction or angina pectoris whole, caused by hypertension or heart valve disease.

When people experience heart discomfort and the hospital that arrives checks, what is mostly used is traditional ECG detection device, For example, twelve-lead electrocardiogram detects, various cardiac problems can be detected more in detail, if but the source of heart discomfort is accidental The symptom of property, for example, cardiac arrhythmia, then be likely to not measure heart condition when morbidity during detection, therefore, in response to this The sporadic symptom of kind, mostly can be by the way of wearing Huo Teshi (Holter) electrocardiograph and carrying out long-time detection, for example, wearing The 24 hours time to a couple of days, it is desirable to record electrocardiogram when there is symptom in this way, and with Huo Teshi electrocardiographs Similar, cardiac electrical event logger (ECG event recorder) is also but to be differently by the way of extended wear, User is allowed to decide the time of record in its sole discretion, for example, when heart is felt ill, and recorded through the mode that button starts Lower electrocardiogram, for example, device but is just recorded each 30 before and after compressing time usually without record when user is by lower button The electrocardiogram of second.And other than being used for recording sporadic symptom, Huo Teshi electrocardiographs are also commonly used for monitoring of cardiac operation or clothes With the heart situation after medicine, to confirm therapeutic effect.

Either Huo Teshi electrocardiographs or cardiac electrical event logger, set-up mode must all paste multiple use with To obtain the electrode of electrocardiogram, and it is connected to a device through connecting line, therefore, user must paste always during measurement Electrode and device is worn with, it is quite inconvenient, it is also easy to generate skin discomfort because pasting electrode for a long time, these are all The reason of allowing user to step back is added, and also will appear sometimes after wearing detection even across long-time, but due to not having morbidity Any electrocardiogram for the sporadic symptom of analysis is not recorded.Moreover, such detection, it is necessary to through health care professional's Assistance could complete setting, for example, pasting for electrode must be provided in hospital, also, be typically to complete for a long time Measurement after, then the electrocardiogram to be got off by doctor's Download History analyzes, and just can know that heart goes out after needing at least a couple of days What problem, so, not only complexity is high, also lacks real-time.

Therefore, for these above-mentioned disadvantages, it is further proposed that improvement be Handheld electrocardio detecting device, through adopting It is solved device extended wear must to be examined in puzzlement with it, and simplification with the dry-type electrode being not required to sticking in Complexity when survey.As disclosed in US7149571 and US7197351, Handheld electrocardio detecting device is set on the surface of device It is equipped with dry-type electrode, ECG detecting can be carried out through the mode of contact hand and/or body surface when there is demand at any time, therefore, no Be limited to wear again in it time and electrode paste, therefore can for longer periods be used for the situation of monitoring of cardiac, moreover, this The ECG detection device of sample is usually also configured with analysis program and display screen, and user can be allowed to learn detection instantly in measurement As a result, need not be examined until being returned to hospital, therefore, quite it is suitble to residential use, also, also provide and have height to itself health of heart The user that degree is concerned about usually voluntarily can periodically understand the simple approach of heart situation.

Later, it with portable electronic device, for example, smartphone is universal, occurs that in recent years and hand The ECG detection device that machine is combined, it is similar with Handheld electrocardio detecting device as disclosed in US8615290, equally adopt With dry-type electrode, difference is only that the manipulation that device is carried out through the operate interface of mobile phone, and such mode, which allows, the monitoring heart The user of dirty demand can reduce the quantity of portable device.

But, the greatest problem that above-mentioned portable Handheld electrocardio detecting device faces, but also in that utilizing Caused by hand is operated.When using both hands form is contacted, as shown in Figure 1, problems faced is exactly that signal is weaker first, by Farther out in both hands and heart distance, along with electrocardiosignal is originally just small, after fainter, it is highly susceptible to ambient noise It influences, and analysis is allowed become difficult, another problem is then that stable operation degree is low, hold very much in such a way that both hands measure Easily when measuring there is a phenomenon where such as hand shake etc. is unstable, thus measured electrocardiogram is caused baseline drift, wave occur The situation of the impact analysis such as deformation, moreover, when user wish hand maintain stablize and muscular tone or specially firmly with When ensuring to contact between electrode, also it is easy to have an impact the electromyography signal of signal analysis due to firmly.

When being contacted by the way of chest using proficiency grip device another side, as shown in Fig. 2, operated compared to both hands, it can Relatively stable, acquired signal is also relatively strong, and only, such mode of operation is scrupled there are one maximum, must exactly raise clothing Clothes can just measure to contact chest, the occasion that can be used be limited naturally, in addition, thoracic cavity caused by breathing because rising Volt can still cause to generate relative movement between the electrode and the electrode for contacting hand in contact chest, can equally influence the measured heart Electrograph.

In addition, Handheld electrocardio detecting device is operated due to that must be held by hand, under the demand for meeting ergonomics, Along with needing to show to be still certain burden in carrying as a result, can not be too small in size；Moreover, because electrode is not always With being set to, therefore, when to be detected, more step is needed, for example, being switched on again after first withdrawing device, could started It is detected, therefore is also possible to therefore miss opportunity of detection.

Furthermore the heart rate monitoring unit with being worn in the way of having another extension using neck, for example, US8668643, US20130345578, US20080287768 and US20070106145 those disclosed herein.Such device is although easy to carry, but Due to touching the mode of body naturally using electrode, electrode surface is applied compared to aforementioned adherent electrode or hand The modes of operation such as power lack fixed strength, therefore the contact between electrode and skin is highly unstable, therefore can not also obtain clear Electrocardiogram that is clear and stablizing, therefore be not appropriate for for judging whether heart exception occurs, such as, if it intentionally restrains not whole, myocardium Electrode is set to the particular arrangement mode of neck along with it by the symptoms such as infraction, is also resulted in using above there is many restrictions.

Therefore, a kind of ECG detection device that can solve disadvantages mentioned above is needed really, and user can more easily use While, the influence of various uncertain factors when operating can also be minimized.

Specific implementation mode

In view of the purpose for allowing user that can record electrocardiogram in real time, the device of the invention is embodied as wearing form, and Many ECG detection device can be set to mode in, the present invention has selected neck to wear, wearing mode as shown in Figure 4, Main reason is as follows.

First, the form hung through neck, device can be placed in naturally in front of trunk, before clavicle lower section, front, abdomen The positions such as side, because as is known in the art, trunk is the strongest region of electrocardiosignal, therefore, such to set Setting the signal acquired by first making sure has enough intensity.

Furthermore compared to the chest strap form that device can be equally set to front, neck wears form to caused by user Small upper many is felt in constraint, thus can provide relatively comfortable use experience.

In addition, neck wear form also allow device can naturally position between clothes and trunk, electrode contact trunk action not Clothes need to be raised just to may achieve, eliminate the limitation of use occasion, allow user no longer to step back because clothing must be lifted, or condescend to take this post in letter Number weaker both hands number of winning the confidence measurement method.

In addition, the present invention uses dry-type electrode, user can use at any time, without the problem of electrode is arranged is worried, saves Go the doubt that must use the trouble of conductive paste and elimination that user may be caused skin discomfort phenomenon occur.

Therefore, mode is worn through using neck, the various disadvantages according to the present invention for overcoming aforesaid known technology, for example, Need to paste electrode, may cause skin is uncomfortable, signal strength not enough, lack real-time, the problems such as clothing measures need to be lifted.

And also due to allowed in the form of neck is worn user can ground free of a burden worn for long periods with, along with can naturally, The enough electrocardiosignals of intensity are easily obtained at any time, and therefore, being quite suitably applied house nurse field for example makes User can in daily life wear device in neck, and at any time whenever necessary, for example, when thinking that heart is uncomfortable, in real time Ground starts ECG signal sampling, or regularly carries out Electrocardiography daily, effectively grasps the heart variation of itself.

Also quite it is suitble to use during exercise in addition, neck according to the present invention wears formula ECG detection device, for example, makes User can have on the apparatus according to the invention and be born without feeling during the motion, and during exercise between time for resting it is straight It connects to be measured and knows movement to the influence caused by heart, such as, if having reached enough exercise intensities, (whether heartbeat Reach target) or heart whether occur abnormal etc., especially movement is the good hair time of cardiac arrhythmia, therefore, through this The device of invention can note down electrocardiogram when lower generation cardiac arrhythmia in real time very much.

Referring to Fig. 3, it shows that neck according to the present invention wears the configured in one piece schematic diagram of formula ECG detection device.As schemed Showing, neck according to the present invention is worn formula ECG detection device 10 and be can be seen that from the appearance depends on component 14 with a shell 12, one, with And at least two electrodes 16, wherein this depends on component 14 and is embodied as being combined with the shell 12, and can adhere to the neck of user Portion, so that the shell 12 is located at the front of user's trunk, for example, the positions such as clavicle lower section, front, abdomen front, such as Fig. 4 institutes Show, and electrode 16 is then positioned at the surface of shell 12.

In a preferred embodiment, electrode according to the present invention is embodied as position on the same surface of the shell, such as Fig. 3 First surface 122 on, also that is, when shell depends on component through this and is set in front of trunk, towards the surface of trunk On, as shown in figure 4, even if being covered in clothes, two contacts between electrode and skin can be also easily achievable, therefore be not required to lift clothing Also it can be detected.And the basis of so embodiment is that, through the form that neck is worn, the shell of the apparatus according to the invention Body is arranged on the position around heart, and the enough positions of electrocardiosignal intensity, the limitation when electrode position is arranged is small, for example, Distance can be very short.

In the present invention, electrode is arranged on shell, rather than on such as band body of known technology, in addition to body top electrode Steady contact is not easy to reach outside, main reasons is that：

First, it is heart signal most clearly sample position as previously mentioned, near heart, that is, body, moreover, by In two electrodes each other very close to circuit loop is short, can avoid all kinds of noise jamming electrocardios and measures, makes an uproar especially for common mode Sound, as 50Hz/60Hz can be excluded easily.

Furthermore when electrode is all located on shell, user can easily penetrate mobile shell with regard to traveling electrode position It sets, and then changes the relative position of electrode and heart, so that it may obtain the electrocardiogram of various different angles.

When carrying out ecg measurement, every two electrode can obtain the electrocardiogram of an angle, it is, the setting of electrode Position determines heart that electrocardiogram is reacted electrically movable projection angle, and since heart is three-dimensional, and generate lesion Cardia may position in any cardiac position, whether occur for example, the inspection of myocardial infarction needs to watch in ecg wave form The ST drifts occurred by myocardial necrosis, but be often possible to not examined under certain angles because the relationship of position occurs for it Feel, at this time, it is necessary to through different angle electrocardiogram be possible to check draw, therefore, obtain the electrocardio of different angle Figure is for judging that heart disease is very helpful.

So when electrode is all located on shell, electrode position can be moved very simply through mobile shell, then be added Upper casing position is in front of body, with heart apart from close, even if short-range movement also can get the prodigious difference of angle difference Electrocardiogram, in addition even if only roll-shell, for example, rectangular shell is rotated by 90 °, it as shown in figs. 5 a-b, can also There is same effect, therefore, through such setting, even a very simple neck wears formula ECG detection device, equally may be used To provide the electrocardiogram of multi-angle for user, and provide more information in relation to heart state.

So for the device of the invention, precisely due to electrode is set on shell, known neck Dai Shixin can be just overcome The shortcomings that electric detection means, and then in the case of not losing signal strength, while user's most convenient and free of a burden being provided Use experience.

In addition, electrode is arranged through the shell with certain degree of hardness, the contact stabilization between electrode and skin is also allowed to obtain It must be promoted, be added, in same housing plane, relative position between the two is fixed for two electrode positions, therefore, even if in survey Occur such as breathing body action during amount, still can effectively maintain good contact stability.

As described above, neck according to the present invention wears formula ECG detection device using dry-type electrode, and therefore, the material of electrode Matter can be as is well known use stainless steel, and be fixed on surface of shell；And alternatively, electrode It can be embodied as, for example, the local conductive coating or shell itself of surface of shell are conductive material, exhausted using coating Edge material and build up electrode position, therefore, can there is various possibilities, there is no limit.

Further, since the present invention wears form using neck, and device is hidden in clothes, therefore, also it is contemplated that using non- Conductive electrode, for example, the electrode form of condenser type, induction type, electromagnetic type etc. can be used, to further increase ease of use, Even if for example, thereby through clothing also can use hand electrocardiosignal if allow the configuration limits of electrode to reduce, in response to operation It is accustomed to and there are more variations.And when using such non-conductive electrode, also using the shell of non-conductive material as electrode, For example, a part for capacitive electrode.

Here, it is to surround the band body of neck that this, which depends on the form that component is easiest to implement, for example, necklace or necklace etc., but It is not limited, as long as can pass through neck and the mode of shell is arranged, all belongs to the range that the present invention is covered, also, it is made Material can also change according to actual demand, for example, it may be band body made of the various materials such as fabric, metal, rubber, does not have It is restricted.

Furthermore it further, also can pass through and depend on component and shell is helped to be oriented, as shown in figs. 5 a-b, lead to The combination between design add-on assemble and shell is crossed, can allow surface of shell with electrode more naturally towards trunk, in turn Ensure correctly contacting between electrode and skin.

Then, referring to Fig. 6, it shows that neck according to the present invention wears the electrocardiosignal extraction electricity of formula ECG detection device Road, including an analogy signal processing unit 22, a processing unit 24, a transmission module 26 and a battery 28, wherein the mould To receive the electrocardiosignal for penetrating electrode 16 and being extracted, which examines quasi- signal processing unit 22 as entire electrocardio The control centre for surveying device, and can be handled the electrocardiosignal extracted, and the transmission module 26 is carrying out external biography It is defeated, and the battery 28 is then provided for electric power required when operation ECG detection device.

Here, electrocardiosignal extraction circuit can be embodied as being placed in the shell 12, alternatively, also being embodied as being scattered in It shell 12 and depends in component 14, or is separately set in and depends in component 14, there is no limit can become according to actual implementation situation Change, for example, this depends on component other than providing the function of supporting shell, can also be embodied as with bearing function, for example, should Form such as tubulose can be embodied as by depending on component, circuit is placed in wherein, here, further, this, which depends on component, may be used also The space for being embodied as its accommodating circuit is communicated with shell；Alternatively, the quantity of the shell also be embodied as it is more than one, with it is accommodating more More circuits, and each surface of shell then can all have electrode, or there is electrode only in partial shell, for example, on shell Starting switch also can be only set, etc., therefore, there is no limit.

When user is in the use apparatus according to the invention, as shown in figure 4, need to will only depend on component 14 is fixed on neck, Device can be placed on naturally in front of trunk, such as clavicle lower section, front, abdomen front, and later, need to only determine has electricity The surface of pole is towards trunk, thus, when in need be detected, so that it may and easily hand is utilized to exert a force shell, And so that surface of shell with electrode is contacted to skin, and start a specific time, for example, 30 seconds, 1 minute, electrocardiosignal Detection, or the time span to be detected is determined according to self-demand.

Here, it should be noted that in general, Handheld electrocardio detecting device mostly can give tacit consent to a time of measuring, for example, 30 seconds or 1 minute, and be automatically stopped after time is up, other than being to consider the duration of heart bursty state, also exist In user need not maintain to measure posture too long, occur more unstable situation to avoid operation by human hand, it is but, of the invention Device is minimized the hand factors of instability due to being the form worn using neck, therefore, user can be allowed according to reality Border demand determines that the time span per secondary measurement for example when device terminates in scheduled 30 seconds time of measuring and is sent out When sound prompting, user still can by Continued depression electrode is not let go allow measurement continue, to allow various heart situations all may be used Completely it is recorded.

Also it should be noted that exert a force to shell, however it is not limited to be which position of hand, for example, it may be hand Finger, palm (palm of the hand or the back of the hand), wrist, arm etc., as long as user feels convenient hand position, can all complete to detect, Moreover, also not limiting using left or right hand, user can freely be detected according to personal habits.

Due to the contact between electrode and skin, what is be dependent on is the shell between force hand and skin, therefore, shell It needs energy correct and the conduction appropriate that will exert a force is to electrode and skin, therefore it is preferred that contact the surface of shell of skin It is embodied as with the structure for promoting electrode contact stabilization, for example, when depending on component shell being set to front, the table Face can be embodied as with cambered surface, to meet the curve of chest；If alternatively, when depending on component shell being set in front of abdomen, The surface can be embodied as plane；Or if when depending on component shell being set to below clavicle, which can implement For curved surface or plane.In addition, particularly, in a preferred embodiment, be arranged electrode housing parts can be embodied as it is projecting Surface of shell, as shown in fig. 7, with allow force more concentrate on electrode contact, can not only contact be allowed to be more easily achieved, can also increased Stability.Therefore, there is no limit.

Furthermore due to hanging form using neck, the size of shell should not be too large, and be born to avoid user's neck Greatly, and in vpg connection, also without specific limitation, for example, it may be rectangle, square, circle or irregular shape Shape, visual actual demand and change.

In addition, the material of shell is also a key factor for influencing electrode contact, being required to exert a force hand passes Electrode is reached, and ensures the steady contact between electrode and skin, therefore, material used in shell can have certain hardness, To ensure the correct reception and registration of strength, for example, plastics, in addition, it also is embodied as flexible material, for example, rubber, to increase Docile degree between skin, therefore, material can equally have different selections, can actual demand and change.

In a preferred embodiment, which can also be embodied as being made of two kinds of materials, as shown in figure 8, also that is, towards Skin, for carry electrode first part's shell 32 use flexible material, with allow the surface contact skin when It waits, deformation can be generated with the fluctuating of contact skin area naturally, make more docile between the two, also allow electrode and skin Contact more stable, and the second part shell 34 other than the surface, so that it may harder material is used, to reach effective Convey pressing strength effect, thus, no matter shell provided position why, the contact between electrode and skin all may not be used It is impacted.

During detection, other than carrying out the extraction of electrocardiosignal, neck according to the present invention wears formula ECG detection device also Can have the function that the information that user is relevant to during detection is provided.For example, the apparatus according to the invention may include a letter Breath provides module, to provide user's information of signal for being relevant to use situation and/or being extracted, wherein the side that information provides Formula includes, but are not limited to screen display, sound variation, vibration variation and visible change, for example, the color of luminescence component, The modes such as brightness change.

And the content of the data provided can also have various possibility, for example, be intended to start when user presses shell When measuring, device can utilize sound notification user detection to start, and notify to use at the end of scheduled detection time Person can terminate push action；Alternatively, can remind the current electrode contact condition of user bad when starting detection or signal quality It is bad etc., allow user to adjust the position of force size or shell；Or it can remind or notify during detection to use Any situation has occurred in person, for example, using sound performance heartbeat variation, as utilized the sound as palmic rate, or use Sound notification heart state, as long indicates different states from minor.In addition, further, can carry upon completion of the assays For user's result.Therefore, the mode and content that information provides are all unrestricted, as long as definitely user can be allowed to obtain Solution.

Neck according to the present invention wears formula ECG detection device due to being disposed in front of the trunk of user, and using to shell Therefore the mode of operation of force coordinates the startup of such operation behavior, device and/or detection, in addition to generally opening power supply And/or start outside the mode detected, can also there are various selections, for example, a switch can be set on shell, it can be by shell Force triggering, and make device into the state of electrocardiosignal extraction can be carried out, with then starter and/or detection；Or Person, alternatively, a physical state detection unit 40 can be connected the electrode to, as shown in figure 9, with detecting electrode in contact skin When a generated physical change, and learn whether the contact between electrode and skin sufficiently stable through the physical change, because And understand whether device can carry out electrocardiosignal extraction.

Here, the physical change includes, but are not limited to pressure change and impedance variations, and for example, the physical state Detection unit 40 may include pressure sensing module, to learn pressure change, and judge whether the pressing suffered by electrode is enough, or It is that the physical state detection unit also is embodied as a switch, it is same it can be seen that the pressure size that electrode is born, or, it should Physical state detection unit also may include impedance sensing circuit or capacitance sensing circuit, to learn that the impedance of electrode, capacitance become Change, and judge whether that ECG detecting can be carried out, therefore, which is embodied as a pressure sensing module, a resistance Anti- sensing circuit, a capacitance sensing circuit or a switch, or two combination at least within, it is unrestricted, also, the physics State-detection component can be embodied as being connected to one of electrode or all electrodes, can be depending on actual implementation situation, together There is no limit for sample.

So when being judged, if the switch does not switch completely and/or the physical change does not meet a preset range, Indicate that the contact condition between electrode and skin is not enough to carry out electrocardiosignal extraction, therefore, device is in electrocardiosignal extraction nothing The state that method is activated, if switching and/or physical change completely indicates electrode and skin when meeting a preset range to the switch The contact for being sufficient for electrocardiosignal extraction is reached between skin, therefore, device is converted to what electrocardiosignal extraction can be activated State.
