Description

Wearable ECG detection device

The present invention relates to a wearable electrocardiographic detecting device, and more particularly to a wearable electrocardiographic detecting device having a structure for actively applying a force to an electrode to provide better ECG signal quality.

It is known that an electrocardiographic detecting device is a main route for examining various heart diseases, for example, whether there is arrhythmia, cardiac hypertrophy caused by hypertension or heart valve disease, myocardial infarction, or a disorder of the heart.

When people feel the heart discomfort and go to the hospital for examination, the traditional ECG detection device is used. For example, 12-lead ECG detection can detect various heart problems in more detail, but if the source of heart discomfort is Occasional symptoms, such as arrhythmia, may not be able to measure the heart condition at the time of onset during the test. Therefore, in response to such sporadic symptoms, a Holter electrocardiograph is used for a long time. The method of detection, for example, wearing 24 hours to several days, is expected to record the electrocardiogram when symptoms appear in this way, and similar to the Hult electrocardiograph, the ECG event recorder is also The long-term wearing method, but differently, allows the user to determine the recording time, for example, when the heart feels uncomfortable, and records the electrocardiogram through the button activation method, for example, the device usually does not record, Instead, the ECG is recorded for 30 seconds before and after the pressing time when the user presses the button. In addition to recording sporadic symptoms, the Hult ECG is also commonly used. Monitor the heart condition after heart surgery or taking a therapeutic drug to confirm the treatment effect.

Whether it is a Hotter ECG machine or an ECG event recorder, it is necessary to attach a plurality of electrodes for obtaining an electrocardiogram to the body and connect to a device through a connecting wire. Therefore, the user must always stick during the measurement. It is quite inconvenient to wear the electrode and wear the device on the body, and it is easy to cause skin discomfort due to sticking to the electrode for a long time. These are the reasons for the user to deter, and sometimes, even after wearing for a long time. After the test, no electrocardiogram for analyzing sporadic symptoms was recorded because there was no disease. Moreover, such testing must be done with the assistance of a professional medical staff member. For example, the electrode paste must be set up in the hospital, and usually after the long-term measurement is completed, the doctor can download and record the recorded electrocardiogram. Analysis, it takes at least a few days to know what is wrong with the heart, so it is not only complicated, but also lacks immediacy.

Therefore, in view of the above disadvantages, a further improvement is a hand-held ECG detecting device which solves the problem of having to wear the device for a long time by using a dry electrode which does not need to be adhered to the body, and simplifies the detection. the complexity. As disclosed in US Pat. No. 7,419,571 and US Pat. No. 7,197,351, the handheld ECG detecting device is provided with a dry electrode on the surface of the device, and the ECG can be detected at any time by contacting the hand and/or the body surface when needed, and thus is no longer restricted. It is more flexible to monitor the heart when it is worn on the body and the electrode is attached. Moreover, such an ECG detection device is usually equipped with an analysis program and a display screen, which allows the user to measure the current moment. That is to say, the test results are not necessary to wait until the hospital is returned to the hospital. Therefore, it is quite suitable for home use, and it also provides an easy way for users who are highly concerned about their heart health to regularly understand the heart condition.

After that, with the popularity of electronic devices that are carried around, for example, smart phones, What has emerged in recent years is an electrocardiographic detection device combined with a mobile phone. As disclosed in US8615290, it is similar to a handheld ECG detection device, and also uses a dry electrode, the only difference being that the device is operated through the operation interface of the mobile phone. This approach allows users with monitoring heart needs to reduce the number of devices they carry with them.

However, the above-mentioned ECG detecting device, whether in the form of a hand-held device or in combination with a mobile phone, can be carried around, but since it must be handled by a hand, it is ergonomically required, plus The result is not too small in size, and it is still a certain burden on the carrier; moreover, since the electrode is not always placed on the body, more steps are required to perform the detection, for example, after the device is removed and then turned on, The detection is started, so it is possible to miss the timing of the detection.

Moreover, the measurement by the two hands is easy to cause an unstable phenomenon such as hand sway during measurement, thereby causing a situation in which the measured electrocardiogram exhibits influences such as baseline drift and waveform deformation, and further, when the user I hope that when the hand is stable and the muscles are tense, or if you deliberately use force to ensure contact with the electrodes, it is easy to exert a myoelectric signal that affects the signal analysis.

Therefore, there is a need for a wearable electrocardiographic detection device that solves the above-mentioned disadvantages, allows the user to use it more conveniently, and minimizes the effects of various uncertainties in operation.

Moreover, when the ECG detecting device can be worn on the body, other physiological information can be further obtained through the obtained ECG signal. For example, the time series of the heartbeat interval can be obtained according to the electrocardiogram to perform HRV (Heart Rate Variability). Mutation rate) analysis, and knowing the activity of the autonomic nerve, can also obtain the relevant RSA by analyzing the time series (Respiratory Sinus Arrhythmia, information on sinus arrhythmia), and then learn about the changes in breathing used, and through this information, can guide the user to perform breathing training that helps improve the balance of autonomic nerves.

Since one of the important causes of arrhythmia is autonomic nervous disorder, when the user wants to immediately record the electrocardiogram when arrhythmia occurs through the wearable ECG detection device, the same device can provide symptoms of arrhythmia improvement. The function, for the user, will be a more complete solution.

It is an object of the present invention to provide a wearable electrocardiographic detecting device in which an electrode system for extracting an electrocardiographic signal is implemented in a wearable form, and the contact between the electrode and the skin can be achieved without the user's application of force.

It is still another object of the present invention to provide a wearable electrocardiographic detecting device that is placed on an ear through an ear-wearing structure and that achieves contact between the electrode and the ear, or the skin in the vicinity of the ear, while being worn.

Another object of the present invention is to provide a wearable electrocardiographic detecting device, which simultaneously disposes two electrodes required for capturing an electrocardiogram on a finger and an ear through a finger wearing structure and an ear wearing structure, respectively. It is easy to wear, and it also minimizes the effect of myoelectric signal interference, and further provides a way to continuously obtain ECG signals for a long time.

Another object of the present invention is to provide a wearable electrocardiogram detecting device which is transparent The device is placed on the wrist through the wrist wearing structure, and the contact between the electrode and the skin near the wrist is achieved while being worn.

Another object of the present invention is to provide a wearable physiological detecting device which has both an electrocardiogram signal and an electroencephalogram signal detecting function, and can realize the electrode and the head while the device is placed on the head through the head-wearing structure.

Figure 13 is a view showing the operation of the head-mounted electrocardiographic detecting device according to the present invention.

The wearable electrocardiograph device according to the present invention includes a control module, a wearable structure, a first electrode and a second electrode, and an information providing unit, wherein the circuit system includes a processor to control the device The overall operation, for example, performing the extraction of the electrocardiogram signal through the first electrode and the second electrode, and the wearing structure is configured to set the device on the user when the ECG signal is captured, to provide use Convenience, the information providing unit is used to provide information to the user, for example, to operate related information, physiological information, and analysis results.

Wherein, the circuit system can be implemented to be housed in the wearing structure, or, further, the device according to the present invention can further include a housing, and the circuit system can be accommodated in the housing and/or Or in the wearing structure, therefore, there is no limitation depending on the actual implementation; in addition, the material of the housing can be implemented to be the same as or different from the wearing structure, for example, if implemented as the same material, it can be formed. In the form of integral molding, if it is implemented as a different material, a suitable material can be selected according to the position to be worn, and there is no limitation.

In addition, since the electrocardiographic detecting device according to the present invention is implemented in a wearable form, the manner in which the information providing unit provides information may have more options, including, but not limited to, visual, auditory, and tactile, and the like. For example, the information providing unit can be implemented as a display element and/or a light-emitting element to provide information by means of text display, graphic change, and/or light number change; or the information providing unit can also be implemented as sounding a module that provides information by changing the frequency or volume of the sound, or by means of voice; or, the information is provided The unit can also be implemented as a vibration module and provide information using changes such as the strength and length of the vibration.

Further, the information providing unit can be further configured to output information to an external device via a wired transmission module or a wireless transmission module to provide the information to the user through the external device, wherein The external device may be, but is not limited to, a personal computer, a smart phone, a tablet computer, or a smart watch, etc., and only needs to be able to provide the information to the user, so there is no limit. .

In the wearable electrocardiographic detecting device according to the present invention, in particular, the first electrode is implemented to contact the user's skin when the entire electrocardiographic detecting device is disposed on the user through the wearing structure. On one surface, that is, the contact between the first electrode and the skin is achieved by the action of placing the wearing structure on the body, so that the first electrode can be achieved without the user having to apply force by himself. Contact with the skin, so the myoelectric interference caused by the muscle tension caused by the operation action can be significantly reduced, which is quite helpful for obtaining good signal quality.

As for the second electrode, there are several implementation options, for example, it can be implemented on another surface of the device other than the surface for the user to touch other parts of the skin, for example, a finger, a part of the skin such as the chest, and it should be noted that the surface for arranging the first electrode and the other surface for arranging the second electrode may be any surface of the wearing structure or the housing There is no limitation on any surface. It is only necessary to note that the first electrode and the second electrode do not contact the same part of the skin of the user. Alternatively, it may be implemented to be placed on the user through a further wearing structure, so that the active contact force of the wearing structure can also be utilized to achieve contact with the skin, and thus, there is no limitation.

Accordingly, in use, the wearable ECG detecting device according to the present invention can be placed on the body by the user, for example, on a finger, on the ear, or on the wrist, etc., in this case, The contact between the first electrode and the skin is achieved, and then, when the need to measure the electrocardiogram occurs, the circuit of the ECG signal can be obtained by simply touching the second electrode to the other part of the skin. The user can easily and easily obtain an electrocardiogram whenever necessary.

In addition, when the second electrode is also disposed on the user through the other wearing structure, the user only needs to set the two wearing structures on the body, and the electrode setting for capturing the electrocardiogram signal is Completed, therefore, the user can press the start button to record the signal for a period of time when it is necessary to record the ECG, for example, 30 seconds or 1 minute, or can also be implemented as an ECG signal capture device. After being worn on the body, recording and/or analysis is started to save the action of pressing the start measurement in order to record the sudden cardiac condition. Therefore, there is no limitation, and the appropriate method can be selected according to actual needs.

In this case, the other wearing structure may also be combined with another housing, and the second electrode may also be implemented on any surface of the other wearing structure or the other housing. It suffices that the contact of the second electrode with the skin can be achieved only when the other wearing structure is placed on the user, and therefore, there is no limitation.

Since the electrocardiographic detecting device according to the present invention is in the form of wearing, the operation of the device and/or the detection of the electrocardiogram can be activated in addition to the manner of generally turning on the power and/or starting the detection. There are various options. For example, a switch can be disposed near the second electrode, which can be triggered by the biasing force of the second electrode in contact with the skin, so that the device enters a state in which the electrocardiographic signal can be extracted, and then starts. Device and / or ECG detection; or, as Alternatively, the second electrode may be connected to a physical state detecting unit to detect a physical change of the electrode when contacting the skin, and through the physical change, whether the contact between the electrode and the skin is sufficiently stable, Therefore, it can be known whether the device can perform ECG signal acquisition. In addition, the first electrode can also be implemented to be connected to a physical state detection unit, without limitation.

Here, the physical change includes, but is not limited to, a pressure change and a change in impedance. For example, the physical state detecting unit may include a pressure sensing module to know the pressure change, and determine whether the electrode is pressed. Sufficient, or the physical state detecting unit can also be implemented as a switch, and the pressure of the electrode can be also known. Alternatively, the physical state detecting unit can also include an impedance sensing circuit or a capacitive sensing circuit. In order to know whether the impedance and capacitance of the electrode are changed, it is determined whether or not the electrocardiogram can be detected, and therefore, it is not limited.

Therefore, when the determination is made, if the switch is not completely switched, and/or the physical change does not meet a predetermined range, it means that the contact state between the second electrode and the skin is insufficient for ECG signal extraction, therefore, the device In a state in which the ECG signal cannot be activated, if the switch has been completely switched and/or the physical change conforms to a predetermined range, it indicates that the second electrode and the skin are sufficient for ECG acquisition. Contact, therefore, the device transitions to a state in which the ECG signal can be activated.

Here, in particular, whether the electrode can be used can be controlled by whether the switch is completely switched, or whether the physical change conforms to the preset range, for example, whether the electrode is turned on or not, that is, the electrode is in an unusable state until After the switch is completely switched, or the physical change meets the preset range, the electrode is converted into a usable state, for example, turned on, so that the clarity of the obtained ECG signal can be further ensured. Conducive to the accuracy of the analysis results.

Furthermore, there are various options for how to activate the device and/or detect after determining that ECG signal acquisition is possible. For example, in a preferred embodiment, the device according to the present invention can be designed as The device will automatically start detecting the ECG signal after a certain period of time, for example, 3 seconds; or in another preferred embodiment, the device will not be converted to a certain time after, for example, 3 seconds later. The status of the ECG signal acquisition is performed. After the status of the ECG signal is continued, the ECG signal detection is started. Therefore, there are various possibilities, but the actual demand changes, and there is no limitation.

In addition, in accordance with the above-mentioned manner of starting and judging, the device according to the present invention can also be implemented in the state of signal capture, but only when the ECG signal feature is detected, or the sampling frequency or signal is adjusted. Magnification to record all possible ECG changes more completely.

Hereinafter, preferred embodiments of the wearable electrocardiographic detecting device according to the present invention will be exemplified.

First of all, according to the concept of the first aspect of the present invention, the wearing structure is implemented as a finger-wearing structure, and therefore, the wearable electrocardiographic detecting device according to the present invention is carried by the finger-wearing structure and is provided to the user. In one finger, here, as shown in FIG. 1A, the finger receiving structure may be in the form of a circuit system, or may be implemented as shown in FIG. 1B, and the finger wearing structure is further combined with In the form of the housing 20, the circuit system can be accommodated in the housing and/or the finger-wearing structure, and thus, depending on the actual implementation, there is no limitation.

Wherein, the first electrode 10 is in a position on the device that can be in contact with the skin of the finger due to the wearing action when the finger-wearing structure is disposed on the finger, and the second electrode 12 is located on the surface On the other surface of the device other than the surface, for example, The surface opposite to the surface, or the surface adjacent to it, only needs to be careful not to touch the position of the skin of the finger.

Here, the main reason for selecting a finger as the position for setting the electrocardiac detecting device is that the finger wearing form is similar to the general user, and is a familiar and no need to re-learn the use mode. The structure is bonded to the finger to complete the contact between the first electrode and the skin. Then, when it is necessary to record the electrocardiogram at any time, it is only necessary to make contact with the skin of the second electrode and other parts of the limb other than the finger. The ECG signal can be taken immediately, and the operation flow and action are simple, natural and convenient. Moreover, by applying force to the finger by the finger-wearing structure, the contact between the first electrode and the skin can be achieved without the user's exertion of force, and the effect of muscle tension on the ECG signal can be minimized.

There are many possibilities for the actual operation, for example, the second electrode located on the surface can be touched by the other hand, as shown in FIG. 2A, or can be touched by moving the hand wearing the device. Other parts of the skin, such as Figure 2B, show the operation of touching the ring to the cheek, and Figure 2C shows the way the ECG signal is taken to contact the torso, so there is no limit.

Here, in particular, since the finger-wearing form is adopted, the user can achieve the ECG signal capture circuit by moving the hand wearing the device to contact other parts of the body, thereby bringing more operations. The possibility also allows the user to select a suitable contact position according to the use environment and needs, and is more convenient.

Therefore, through such a concept, the user can easily obtain an electrocardiogram with different projection angles by contacting different positions, which helps to judge the condition of the heart more accurately. FIG. 3 shows the general standard 12 Contact position of the electrocardiogram, by means of the invention Refers to the wearing ECG detection device, the user will be able to easily wear the device on the left hand finger, and through the contact points of V1 ~ V6, respectively, to obtain ECG projection of the heart at different angles.

In the measurement of electrocardiogram, an electrocardiogram of one angle can be obtained for each two electrodes, that is, the position of the electrode determines the projection angle of the electrical activity of the heart reflected by the electrocardiogram, and since the heart is three-dimensional and produces a diseased heart The site may be located at any heart position. For example, the examination of myocardial infarction needs to see if there is ST drift in the ECG waveform due to myocardial necrosis, but it may not be noticeable at certain angles due to its positional relationship. At this point, it is necessary to check through the ECG of different angles. Therefore, obtaining an ECG with different angles is very helpful for judging heart disease.

Here, the position of the finger-wearing structure according to the present invention on the finger is preferably a knuckle where the proximal phalanx or the middle phalanx is located, so as to avoid the situation in which the hand is detached due to the position approaching the end of the finger, for example. In terms of the wearing structure, as shown in FIG. 4A, in the form of a general ring, or as shown in FIG. 4B, the flexible tape body surrounding the finger is in the form of a casing, or As shown in FIG. 4C, the embodiment is implemented only in the form of a flexible strip or in the form of an open C-ring, and there is no limitation; here, regardless of the form, the outer diameter can be further adjusted. Structure to further ensure contact stability between the electrodes and the skin, for example, the ring can be implemented as a mechanism with a variable ring to accommodate different wearer's fingers, and the belt can be implemented with an adjustable fixed position, For example, by setting the devil's felt so that the user can select the tightness when wrapping, etc., the embodiment can be changed according to the actual situation, and there is no limitation; in addition, the form of a clip can be used to clamp the knuckle or It is also a good choice for fingertips and for achieving a fixed effect through the elasticity of the clip itself.

Furthermore, it can also be implemented as a finger sleeve provided at the fingertip, as shown in FIG. 4D. That is, a groove structure into which a finger can be inserted, for example, in the form of a ring or a cavity, and the first electrode is disposed on an inner surface of the groove structure, and the inner surface is configured to conform to a surface of the finger to achieve contact between the first electrode and the skin of the finger when the finger is extended, wherein the groove structure can be made of a resilient material, such as rubber or silicone, to achieve an electrode to the skin The contact, or alternatively, may be formed with a plastic casing, and an elastic material is provided inside to cover the finger, or a structural design that provides an inward force to ensure the internal electrode and the skin of the fingertip. Good contact, therefore, no restrictions. Such a form is advantageous in that it is easier to access different positions to achieve an ECG of different projection angles. Therefore, the finger-type ECG detecting device according to the present invention can be implemented in various forms according to actual needs without limitation.

In addition, in a preferred embodiment, the housing 20 can also be connected to the finger wearing structure through a connecting wire and disposed on the wrist of the limb where the finger is located through a wrist wearing structure, as shown in FIG. 4E. In this way, a hardware configuration, such as a circuit, a battery, or the like, which is originally placed in the vicinity of the finger and coupled to the finger-wearing structure, can be moved to the wrist to reduce the burden of the finger when the device is worn, and the wrist wear The structure and/or the surface of the housing that is not in contact with the wrist may also serve as a position for the second electrode to provide another contact option for the user or, as shown in FIG. 4F, Both the wearing structure and the wrist wearing structure have a housing, and therefore, there is no limitation.

Furthermore, in another preferred embodiment, the housing 20 can also be implemented to be coupled to the finger-wearing structure through a connector, as shown in FIG. 4G, in which case the first electrode 10 is in contact. The right hand finger and the second electrode 12 contact the skin near the wrist of the left hand, and since the finger wearing structure is placed on the wrist by being combined with the housing disposed on the wrist, when the user places the hands on the fixed On the surface, for example, on the table, when measuring, it will form very Stable measurement posture, so that the generation of myoelectric signals is minimized. In addition, the circuit of ECG detection can be shortened by the form of connector connection, so that the electromagnetic interference in the environment induced by the connection line can be mixed. The news is reduced to a minimum, so it is also a very favorable option.

Furthermore, according to another aspect of the present invention, the wearing structure is implemented as an ear wearing structure, and therefore, the wearable electrocardiographic detecting device according to the present invention is carried by the ear wearing structure, and is thereby provided to the user. On one of the ears, the circuitry is housed within the ear-worn structure and/or additionally included in a housing.

Wherein, as shown in FIG. 5A, the first electrode 10 is tied to a skin on the device that can be in contact with the skin of the ear or the vicinity of the ear due to the wearing action when the ear wearing structure is disposed on the ear. On the surface, the second electrode 12 is located on the other surface of the device except the surface, for example, may be the surface opposite to the surface, or the surface adjacent thereto, only need to pay attention to Do not touch the position of the ear or the skin near the ear. Here, the first electrode 10 can also be implemented to have two electrodes, as shown in FIG. 6A, and one of the electrodes is used as a ground or reference electrode to suppress common mode noise, for example, noise from a power source. Therefore, there is no limit to implementation.

Here, the advantage of using the ear as the position of the contact electrode is that the ear and its vicinity are areas where the myoelectric signal is extremely small, and a relatively stable relative positional relationship with the head, even if the user is in the measurement period. The body moves, for example, slightly turning the body, or turning the neck, the contact between the electrodes and the skin remains stable, and does not cause too much interference that affects the measurement results.

In addition, in general daily life, the ear is a part that is less covered by the clothing than other body parts, and can be easily contacted directly when needed, and further, the ear The skin around it and the skin also have less hair characteristics, and the contact between the electrodes and the skin can be easily achieved without barriers, and is therefore a convenient choice for the user.

Therefore, in actual operation, as shown in FIG. 5B, the user can easily achieve the ECG signal capture circuit by simply touching the second electrode on the device worn on the ear by hand, which is quite convenient.

In addition, in a preferred embodiment, the housing 20 can also be connected to the ear wearing structure through a connecting wire and disposed on a wrist through a wrist wearing structure, as shown in FIG. 5C. A hardware configuration, such as a circuit, a battery, or the like, that is originally associated with the ear-worn structure near the ear, can be moved to the wrist, with the burden of the ear when the device is worn, and/or the wrist-worn structure and/or the The housing can also be used as a position for arranging the second electrode, for example, a position for the user to touch the other hand, or a position where the wrist of the housing can be contacted, etc., to provide another contact option for the user, or Both the ear-wearing structure and the wrist-worn structure have a housing as shown in Fig. 5D, and therefore, there is no limitation.

Here, the embodiment of the ear-wearing structure according to the present invention may have various options, for example, a fixing method commonly used in daily life, such as ear hooks, earplugs, ear clips, etc. shown in Figures 6A-6C, for the user. It does not need to be re-learned, and it can be configured naturally. Therefore, the user can simply complete the electrode setting by simply wearing the earphones; and when the electrodes are placed on the ear through the above fixed manner, The contact between the electrode and the skin can be achieved without the user's exertion of force, and the interference of the myoelectric signal can be minimized, and a good quality signal can be obtained.

In addition, in particular, in a preferred embodiment, the earwear structure is implemented to be attached to the ear by means of a magnetic force, for example, two components that are magnetically attracted to each other across the ear, and The electrode is disposed on one of the components, and the two components can be implemented as both All of them are magnetic, or one part has a magnetic force, and the other part can be attracted by a magnetic force, and there is no limitation. Here, the magnetic force can be made by disposing a magnetic substance inside the part or directly by a magnetic substance, and Similarly, the substance attracted by the magnetic force may be disposed inside the component or used to form the component.

As for the position on the ear to obtain the ECG signal, there is no limit, and it can be any position of the ear itself, for example, in the ear canal, the earlobe, the inner surface of the auricle, for example, the ear cavity, the ear canal, etc., the ear wheel And the back of the auricle, as shown in Fig. 7, the area near the ear, for example, the skin near the junction of the ear and the head, etc. These positions are the locations where the electrodes can be contacted and the ECG signal is obtained.

In addition, since the setting position is an ear, the ear-mounted electrocardiographic detecting device according to the present invention is also suitable for combination with an earphone, for example, a wired or wireless earphone, in addition to allowing the electrocardiographic detection to be more integrated into daily life. In addition, it can also exert greater effects through the sounding function of the earphone. For example, the user can provide the result of the analysis by sound and/or voice, for example, to remind the user that the ECG signal is abnormal, or to remind the user to record the time. Electrocardiogram, etc., is more convenient.

Here, it should be noted that both ears are selectable wearing positions. However, it has been experimentally found that the contact position of the second electrode has a considerable influence on the signal quality, wherein when the second electrode is implemented In order to contact the left upper limb, the quality of the ECG signal obtained is much better than that obtained by contacting the right upper limb. Therefore, when the ECG measurement is performed in contact with the ear, it is preferable to contact the left upper limb. The second electrode prevents the signal quality from being bad due to contact with the right upper limb, which leads to misjudgment in the analysis.

And, in particular, according to another aspect of the present invention, the first electrode and the second electrode may be further implemented by the finger-wearing structure and the ear-wearing structure, respectively. In contact with the skin, as shown in Figures 8A-8B, the user only needs to wear the wearing structure on the ear and the finger respectively, that is, the electrode configuration required for measuring the ECG signal is completed, which is equivalent. Conveniently, the contact between the two electrodes and the skin is achieved by the active application of the wear structure, and the myoelectric signal interference caused by muscle tension can be minimized.

Here, as shown in FIGS. 8A and 8B, the housing may be combined only on a single wearing structure, or the housing may be provided on both wearing structures, without limitation, and the circuit system is also the same. It can be accommodated in any wearable structure and housing without limitation, and is changed according to actual needs.

In addition, in addition to the electrocardiographic electrodes on the finger-wearing structure, the electrocardiographic electrodes disposed on the ear can also be combined with the electrocardiographic electrodes disposed at other locations to obtain ECG signals, such as the neck, shoulders, upper arms, forearms, etc. The position, for example, can be placed around the neck and shoulders through a neck-wearing structure such as a necklace or a collar, or can be placed on the arm through an arm-worn structure or a wrist-worn structure, which is also quite convenient. Therefore, any electrode placement position capable of projecting an electrocardiogram is within the scope of the present invention.

According to a further aspect of the present invention, the wearing structure is implemented as a wrist-worn structure, and therefore, the wearable electrocardiographic detecting device according to the present invention is carried by the wrist-worn structure and is disposed on a wrist of the user. And the circuitry is housed within the wrist-worn structure and/or further included in a housing.

Wherein, as shown in FIG. 9A, the first electrode 10 is tied to a surface of the device that can be in contact with the skin near the wrist due to the wearing action when the wrist-worn structure is disposed on the wrist. The second electrode 12 is located on the other surface of the device other than the surface, for example, may be the surface opposite to the surface, or the surface adjacent thereto, only need to note This means that you will not touch the position of the skin of the wrist where the wrist is located. Here, the first electrode 10 can also be implemented to have two electrodes, as shown in FIG. 9B, and one of the electrodes is used as a ground or reference electrode to suppress common mode noise, for example, noise from a power source. Therefore, there is no limit to implementation.

Here, the main reason for selecting the wrist as the position for setting the electrocardiographic detecting device is that since the wrist-worn form is the same as the wearing of the watch, it is familiar and does not need to be re-learned, and the wrist is directly worn. The wearing structure is combined with the wrist to complete the contact between the first electrode and the skin. Then, when it is necessary to record the electrocardiogram at any time, it is only necessary to contact the second electrode with the skin other than the limb of the finger. The ECG signal can be taken immediately, and the operation process and action are simple, natural and convenient. Moreover, by applying a force to the wrist of the wrist wearing structure, the contact between the first electrode and the skin can be achieved without the user's exertion, and the influence of the muscle tension on the ECG signal can be minimized.

Therefore, in actual operation, as shown in FIG. 9C, the user can easily reach the ECG signal capture circuit by using the hand to contact the second electrode, which is quite convenient. In addition to the form in which the housing is carried on the wearing structure, the circuit can be accommodated in the wrist-worn structure as shown in FIG. 9D, and thus, there is no limitation.

And, in particular, according to the concept of still another aspect of the present invention, further, as shown in FIG. 9E-9F, the first electrode 10 and the second electrode 12 are implemented by the wrist-worn structure 90 and Refers to wearing the structure 92 to achieve contact with the skin, so that the user only needs to wear the wearing structure on the finger and the wrist, that is, the electrode configuration required for measuring the ECG signal is quite convenient, and The contact between the two electrodes and the skin is achieved by the active application of the wearing structure, and the user can reach the contact with the electrode without applying force, and if the user can put both hands in the measurement On a fixed plane, it will be caused by muscle tension EMG interference can be minimized and is quite advantageous.

Furthermore, the wrist-worn electrocardiographic detecting device according to the present invention may further include a connecting port 14 electrically connected to a third electrode 16 through a connecting wire as shown in FIGS. 10A-10C. The third electrode may be further implemented to replace the function of the second electrode. For example, the second electrode may be automatically disabled when the third electrode is connected to the connection port, or may be switched through a switch. The switch allows the user to decide which electrode to activate, and the embodiment is not limited. In addition, the third electrode 16 can also be implemented to achieve skin contact by wearing the structure, for example, an ear wearing structure (eg, Figure 10B shows), refers to the wearing structure (as shown in Figure 10C), or the wrist-worn structure.

Alternatively, the third electrode 16 can also be connected through a connector, as shown in FIG. 10D. At this time, the first electrode 10 contacts the wrist of the user by wearing the wrist-worn structure, and The three electrodes 16 are positioned in the finger-wearing structure. In this case, since the finger-wearing structure is combined with the device on the wrist through the connector, a relatively stable measurement posture can be achieved, which is more helpful to obtain. High quality ECG signal.

When the third electrode is extended through the connecting wire as shown in Figs. 10B-10C, the device of the present invention can provide more contact position selection to obtain different hearts than the second electrode positioned on the surface of the device. An angle-projected electrocardiogram, for example, when the second electrode is used, the angle of projection of the heart is obtained by both hands (the wrist wearing the wrist-worn structure and the hand contacting the second electrode), and the third electrode is used. An ear-wearing structure can be provided to contact the ear (eg, a left hand wearing a wrist-worn structure and a left ear wearing an ear-worn structure) to achieve an electrocardiogram of different cardiac projection angles.

As mentioned earlier, the heart part of the lesion may be located in any heart position. For example, the examination of myocardial infarction needs to see whether there is ST drift in the ECG waveform due to myocardial necrosis, but when the location of the lesion cannot be detected at certain angles, the ECG of different angles is necessary.

Therefore, the device of the present invention allows the user to perform electrocardiographic signal measurement by contacting the second electrode on the surface by means of extending the third electrode, and can simply reconnect the connection when needed. An electrode way to get more information about the heart.

In addition, the extended third electrode further provides other advantages in use.

In the present invention, the arrangement of the second electrode allows the user to easily and quickly obtain the ECG signal by touching the surface electrode as needed, and the extended third electrode provides the user. Another option to get a stable signal. Since the third electrode is in contact with a part of the skin of the user's body when the third electrode is used, the muscle tension and the hand shaking which are most likely to affect the quality of the electrocardiographic signal can be excluded. In turn, a more stable and high quality ECG signal is obtained.

In addition, with respect to the hand touching the second electrode, the third electrode extending through the connecting line as shown in FIG. 10B-10C also allows the user to select a measurement position with a strong ECG signal, for example, from the heart. Close position, so that the influence of the interference signal is reduced. For example, the same size of the myoelectric signal can be excluded in the case of a strong ECG signal, but in the case of a weak ECG signal, it is likely to be incompatible with the heart. The difference between the electrical signals and the misjudgment is made. Therefore, the user can set the third electrode to a position where a strong ECG signal can be obtained, thereby generating the correctness of the analysis result.

Therefore, the wrist-worn electrocardiographic detecting device according to the present invention has two operations. a mode, a first mode of operation, and a second mode of operation, in the first mode of operation, the first electrode and the second electrode are combined to form a first electrocardiographic signal capture circuit to obtain a first electrocardiogram, and In the second mode of operation, the first electrode and the third electrode together form a second ECG acquisition circuit, thereby obtaining a second electrocardiogram, and through such an optional operation mode design, even if facing different operations A stable and high-quality ECG signal is available for both the environment and the habits of use.

In addition to the wrist-worn electrocardiographic device, the finger-mounted ECG detecting device and the ear-mounted ECG detecting device according to the present invention may be implemented to have a connection port for connecting a third electrode. , replacing the second electrode.

For example, as shown in FIG. 11A, the wearable electrocardiographic detecting device can connect a finger-type third electrode through a connecting wire, and as shown in FIG. 11B, the ear-mounted electrocardiographic detecting device can also pass through the connecting wire. And connecting a finger-type third electrode, both of which make the operation mode that originally needs to be contacted with the hand electrode replaced by a finger-wearing structure that can provide an active force, so that it may be generated due to hand contact. The instability factor can be eliminated to help achieve a more stable signal; in addition, as shown in Fig. 11C, the wearable ECG detection device can also be connected to an ear-mounted third electrode, except that no force is applied. In addition to the measurement method, a cardiac projection angle electrocardiogram different from the two-hand contact electrode is also obtained. Therefore, there is no limit.

Further, the wearable electrocardiogram detecting device according to the present invention may be configured to obtain a first electrocardiogram through the first electrode and the second electrode, and obtain a second electrocardiogram through the first electrode and the third electrode. As shown in FIG. 12A and FIG. 12B, that is, the first electrode forms an electrocardiographic detection circuit with the second electrode and the third electrode simultaneously when the measurement is performed, so that the user can follow the Choose different modes of operation for different needs, Get the heart information closest to your needs.

Furthermore, according to a further aspect of the present invention, the wearing structure is implemented as a head-mounted structure, and therefore, the wearable electrocardiographic detecting device according to the present invention is carried by the head-mounted structure and is provided to the user. The circuitry is housed within the housing and/or additionally included in a housing.

As shown in FIG. 13, the first electrode is located on a surface of the device that can be in contact with the skin of the head due to the wearing action when the head structure is disposed on the head, and the second electrode 12 is located on the other surface of the device except the surface to contact the skin of the upper limb (eg, finger, arm), neck, shoulder, etc., thereby achieving an ECG signal capture circuit. Here, it should be noted that the second electrode can be disposed at various positions, for example, on a surface opposite to the surface of the head structure or on a surface adjacent thereto. Touching the upper limb or touching the skin of the upper limb through a finger-worn structure, a wrist-worn structure, or an arm-worn structure; or, alternatively, an ear-worn structure that can be attached to the ear, and the first The second electrode is disposed on the exposed surface of the ear-wearing structure for the user to make contact with the upper limb; or alternatively, the second electrode may be extended to a position such as a neck or a shoulder through the connecting wire, for example, The neck-wearing structure of the collar and necklace can also obtain the ECG signal. Therefore, there are various possibilities and no restrictions.

Here, the head-wearing structure can also be implemented in various forms, for example, a belt body, a headgear, or a hard head frame with an adjustment mechanism, or a form of glasses, etc., with an emphasis on achieving electrode-to-skin contact. Therefore, there is no limit.

The head and the ear have similar characteristics, and it is not easy to generate a myoelectric signal that interferes with the ECG signal. Therefore, it is also suitable for setting the position of the electrocardiographic electrode, and The structure may further include an EEG electrode to obtain an EEG signal. For example, only at least two EEG electrodes are disposed on the inner side of the head-mounted structure, or in the head-wearing structure when the ear-wearing structure is fitted And an EEG electrode is disposed on the inner side of the ear-wearing structure to contact the EEG sampling point on the head. For example, common sampling points include Fp1, Fp2, O1, O2, A1, A2, etc., or any basis according to 10-20 The position defined by the system can provide users with more detection functions without increasing the burden, which is quite advantageous.

Moreover, the electrocardiographic electrode disposed on the head structure for contacting the skin of the head, that is, the first electrode, may further share as an electroencephalogram electrode, and form an electrocardiographic signal extraction circuit with the second electrode, and Forming an EEG circuit with an other EEG electrode.

Alternatively, the shared method can also be implemented by using two electrodes simultaneously for obtaining the ECG signal and the EEG signal, that is, the ECG signal and the EEG signal are obtained through the same physiological signal acquisition circuit. Here, the reason for this can be that the ECG signal is much larger than the EEG signal, wherein the ECG signal falls within the range of millivolts (mV), and the EEG signal falls within the range of microvolts (μV). Therefore, even if they enter the same input of the physiological signal capture circuit, the two can be distinguished from each other.

In the implementation, for example, an electrode contacting the head can be used to cooperate with another electrode that can simultaneously contact the head and the hand to obtain the ECG signal and the EEG signal, wherein the simultaneous contact head The electrode of the part and the hand, for example, the most common metal electrode piece can be electrically connected to the two electrode pieces contacting the hand and the head, or can be implemented as two parts of one electrode piece respectively contacting the hand And the head, for example, when placed on the headgear structure, contacts the skin of the head and the skin of the outside hand on the inside, and therefore, the embodiment is not limited.

Accordingly, the electroencephalogram electrode is also suitable for the ear as shown in Figures 5-6 and 8 Wear the structure. First, there are areas in the vicinity of the ears and ears that detect the activity of the cerebral cortex, for example, the temporal lobe. Furthermore, in the field of EEG detection, the ears are separated from the head due to their structure and position. It is not easily affected by brain activity, so it has always been regarded as one of the best positions for setting the reference electrode. Therefore, the reference electrode is combined with the ear in the ear-wearing structure, which is common in EEG detection. Therefore, the ear-mounted electrocardiographic detecting device according to the present invention is also quite suitable for combining and providing an electroencephalogram electrode to obtain an electroencephalogram signal, and is also suitable for adopting a common electrode, that is, simultaneously using the first electrode Implemented as an EEG electrode.

Further, in the embodiments of FIGS. 5-6 and 8 , in addition to the two electroencephalogram electrodes being disposed on the ear-wearing structure, a head-mounted structure may be additionally connected to set an electroencephalogram electrode. In this way, the EEG signal can be obtained through the EEG electrodes respectively disposed on the head-mounted structure and the ear-wearing structure, and the ear-wearing structure is exposed through the ECG electrode disposed in the ear-wearing structure. The electrocardiographic electrodes on the surface (Figs. 5-6) or the electrocardiographic electrodes of the electrocardiographic electrodes (Fig. 8) placed on the finger-like structure obtain ECG signals, thereby providing various possible implementation options.

In actual use, the electrocardiographic detecting device according to the present invention provides a possibility of continuously and continuously obtaining an electrocardiographic signal during wear due to the design of the wearable form, and thus provides the user with more convenient functions.

Firstly, since the wearable form allows the user to wear on the body without burden, it is quite suitable for wearing in daily life. For example, the user can wear the device on the ear and on the finger in daily life. On the wrist, or on the wrist, when you need it at any time, for example, when you feel uncomfortable, start the ECG detection immediately, or perform ECG detection regularly every day to effectively control your heart changes.

In particular, the occurrence of arrhythmia is often unwarranted. Therefore, the electrocardiogram detecting device worn on the body can instantly record the electrocardiogram when the arrhythmia occurs, or the electrocardiogram when the user feels that the heartbeat is irregular. As a basis for doctors to determine whether they have arrhythmia.

For example, whether using an electrocardiographic device in the form of finger-wearing, ear-wearing, or wrist-worn, the user may feel uncomfortable or want to record an electrocardiogram by touching the second electrode with the hand. Obtaining an electrocardiogram in a timely manner, as shown in FIG. 2A, FIG. 5B, and FIG. 9C; alternatively, if the second electrode is disposed on the body through the wearing structure or the third electrode is used, The two electrodes of the ECG signal are all in contact, so the user only needs to activate the ECG measurement. For example, by pressing the start button, the ECG can be recorded instantly. In any case, it is quite simple and convenient to use.

Here, the device according to the present invention can be set to automatically record the next fixed time electrocardiogram after the electrocardiographic measurement is activated, for example, 30 seconds or 1 minute, so that the user can easily record the heart immediately when it feels uncomfortable. For example, when an arrhythmia occurs, the electrocardiogram.

In addition, the user can also choose to record a continuous electrocardiogram for a long time, especially when both electrodes are placed on the body through the wearing structure, and by analyzing the electrocardiogram continuously obtained for a long time, the user can obtain more News.

For example, information on a continuous heart rate sequence can be obtained from a continuous electrocardiogram for HRV (Heart Rate Variability) analysis. HRV analysis is the most important method for observing autonomic nervous activity. Through the analysis results produced by HRV analysis, detailed information on autonomic nervous activity can be obtained, for example, sympathetic activity, parasympathetic activity, autonomic balance, and The activity of the autonomic nervous system as a whole, and more and more Studies have shown that many diseases, such as headache, gastrointestinal discomfort, high blood pressure, insomnia, depression, etc., may be caused by autonomic nervous disorders. Therefore, through the long-term continuous HRV analysis results, we can know the changes of autonomic nerve activity in daily routine, and then explore whether any behaviors or emotions in daily life lead to autonomic nervous disorders, and whether the above diseases are caused by autonomic nerves. Disorders, etc.

Moreover, since the device according to the present invention is in the form of wear, the result of the instant HRV analysis can also be provided to the user through the information providing unit, so that the user can immediately know which behaviors or emotions are present. It is possible to cause an autonomic nervous imbalance, and further, with the design of the present invention, the user can immediately perform physical and mental adjustments, for example, relaxing the body and mind, and knowing whether the autonomic nerve has returned to a more coordinated state.

In addition, when used during sleep, the HRV analysis of the continuous electrocardiogram during sleep can also be used to understand the physiological changes during sleep. For example, the sleep cycle can be judged, and the sleep quality can be understood, which is quite convenient.

Here, it should be noted that after the ECG signal is obtained, the device according to the present invention can be implemented to store the ECG signal first, and after the measurement is completed, output the signal for further processing, for example, output to a computer device. Storage and analysis, etc.; and/or, since the device of the present invention has an information providing unit, relevant information or analysis results can be immediately provided to the user, for example, average heart rate, HRV analysis results, etc., and/or The information providing unit can also be implemented to instantly transmit the recorded ECG signals and/or data to an external device, such as a mobile phone, a tablet computer, etc., for immediate display and/or analysis by the external device. Therefore, there is no limit.

Furthermore, the wearable electrocardiographic detecting device according to the present invention also provides a user The means of breathing training can be carried out with you. By wearing the body, the device according to the present invention can obtain a continuous ECG signal and obtain a time series of heartbeat intervals, that is, a heart rate sequence, and by analyzing the heart rate sequence, relevant sinus arrhythmia can be obtained (Respiratory) Sinus Arrhythmia (RSA), the so-called RSA refers to the phenomenon that the heartbeat changes due to the influence of the autonomic nervous system in the case where the heart rate is controlled by the autonomic nervous system. Generally, the inhalation period will occur. The heartbeat is accelerated, and the heartbeat is slowed down during breathing, so the pattern of changes in breathing and the activity of the autonomic nerve can be known by observing the RSA.

In addition, since breathing is a physiological activity that is controlled by autonomic nerves and can be affected by consciousness, it can affect the self-regulating nerve by consciously adjusting the breathing to achieve the effect of relaxing the body and mind. Among them, according to research, the breathing rate (respiration) Rate), tidal volume, and ratio during expiration/inhalation are factors that affect sympathetic and parasympathetic activity. Among them, slower rate can reduce the activity of sympathetic nerves, while faster rate will increase sympathetic nerve activity. For example, the average adult's breathing rate falls within the range of 10-18 times per minute. When the rate of breathing can be reduced to 5-8 times per minute, it can help increase parasympathetic activity. The activity of the parasympathetic nerve can also be improved when the ratio during the exhalation/inhalation period is increased, that is, when there is a longer exhalation period relative to the inspiratory period.

Therefore, in general, breathing training is performed by providing a breathing guide that the user has a breathing pattern that helps to relax the body and mind. For example, the breathing guide provides a minute per minute that reduces sympathetic activity. -8 times of breathing rate, and / or in the case of natural breathing, during the extended exhalation period, to guide the user to lower the breathing rate and / or increase the exhalation period, thereby increasing parasympathetic nerve activity, inhibiting sympathetic nerves, And the body can be lifted from tension and relaxed.

Moreover, since autonomic nervous disorder is also one of the important causes of arrhythmia, the device of the present invention provides a respiratory guide in the case where one of the purposes of the user using the device is to immediately record the electrocardiogram when arrhythmia occurs. Introducing the training function to allow the user to change the way of autonomic nerve balance by controlling breathing will help to improve the symptoms of arrhythmia, which complement each other and make more sense.

When breathing training is performed using the wearable electrocardiographic detecting device according to the present invention, the user only needs to wear the device on the body and maintain contact between the two electrodes and the skin, and during the breathing training, the The information providing unit is configured to provide a breathing guide signal to the user to allow the user to follow the adjustment of the breathing. In addition, the information providing unit can also provide a physiological state change during the breathing training of the user, for example, sympathetic nerve. Changes in activity with negative sympathetic nerves, changes in heart rate, and changes in actual breathing patterns are used as a reference for breathing training for users.

Here, since the breathing exercise is performed for a long time, it is preferable that the user can select a form in which both electrodes are disposed on the body through the wearing structure, for example, using the second electrode disposed through the wearable structure. Or use the third electrode to cooperate with the first electrode for ECG signal extraction, and perform breathing training in an easier way.

In addition, the breathing guide signal may also be a dynamic guiding signal adjusted according to the breathing change pattern obtained by the heart rate sequence, that is, the breathing state of the user obtained through the instant, so as to know the breathing rate. And/or whether it falls within the range of speeds that are conducive to relaxation, and dynamically adjusts the guidance signal so that the user can achieve the effect of breathing guidance training in the most relaxed and comfortable way.

Or, because increasing the amplitude of the RSA helps trigger a relaxation response (Relaxation) Response), relieves the cumulative pressure, and achieves the effect of increasing the proportion of parasympathetic/sympathetic nerve activity. Therefore, by observing the user's heart rate change pattern, and guiding the user to start inhaling through the guidance when the heart rate starts to accelerate, And when the heart rate begins to slow down, the user is informed through the guide that the exhalation can be started, so as to increase the amplitude of the RSA and achieve the purpose of relaxing the body and mind.

Furthermore, it is also possible to know whether the breathing and heart rate are harmonious and synchronized by the frequency domain analysis of the heart rate sequence, and the better harmony and synchronization between breathing and heart rate represents a more orderly and coordinated heartbeat rhythm. That is, the human body is in a state of relaxation and stability. Therefore, when the user obtains relevant information while performing training, the physiological state of the person can be changed through consciousness.

In addition, when the EEG signal can be obtained by cooperating with the EEG electrode, the heart rate, the respiration and the synchronization between the EEG signals can be observed to understand the physiological state of the user. Because, according to research, exhalation and inspiration cause fluctuations in blood flow in the blood vessels, and this fluctuation also reaches the brain with blood flow, which causes fluctuations in brain waves in the low-frequency segment. Whether the synchronization between the two is achieved by resonance, the breathing pattern can be known by observing the brain waves, and the sinus node and vascular system of the heart are regulated by the autonomic nervous system, and the autonomic nervous system is also The heart rate and blood pressure will be fed back to the brain through the baroreceptor, which will affect the function and operation of the brain. In addition, consciously controlling the breathing can cause heart rate changes due to the influence of the autonomic nerve. Therefore, There is a relationship between the two, so the good synchronicity between the three can represent the human body in a more relaxed state. According to this, the analysis result of the related synchronization can also be used as a self-consciousness adjustment for the user. Information for physiological feedback.

For example, the information providing unit can provide the information about the heart rate and/or the synchronization of the related breathing and heart rate obtained through spectrum calculation while providing the breathing guide signal. You can immediately know the effects of breathing adjustment on the autonomic nervous system, for example, whether the activity of the parasympathetic nerve is improved, or whether the activity of the sympathetic nerve has decreased, etc., so that the respiratory guidance signal can be used. The physiological feedback program performed is more efficient.

In addition, the results of the HRV analysis can be further used to inform the user of the effectiveness of the breathing training. For example, the HRV analysis can be performed before and after the breathing training, and the effect of the breathing training on the autonomic nerve is learned, even It can also be implemented as an instant HRV analysis, and through the information providing unit, the user can immediately know the activity of the autonomic nerve, and the user can instantly understand the physiological state of the patient in a physiologically similar manner, which further helps to achieve Relax and unwind.

Since the HRV analysis analyzes the heart rate sequence over a period of time, the real-time HRV analysis can be performed by moving the concept of the Moving Window, that is, first determining a time period, for example, 1 minute. Or 2 minutes, after that, by continuously changing the time zone backwards, for example, every 5 seconds, the HRV analysis result can be obtained continuously, for example, an HRV analysis result is obtained every 5 seconds, thus achieving the offer For the purpose of real-time HRV analysis results, in addition, the concept of weighting can also be used to moderately increase the proportion of physiological signals closer to the analysis time, so that the analysis results are closer to the immediate physiological condition.

The information providing unit can have various choices when providing the breathing guide signal, for example, it can be guided in a visual, audible, and/or tactile manner without limitation. Vision The choice of the sense guide includes, but is not limited to, a graphical change, a text display, a change in the brightness of the light, and/or a change in the number of the light, etc., all of which are suitable means, for example, utilizing a pattern of breathing change in the display element. The pattern guides the user to inhale and exhale; or the amount of LED light changes to represent inhalation and exhalation; or the text can be used to directly inform the user to inhale and exhale.

In addition, when the method of auditory guidance is adopted, the selection includes, but is not limited to, sound changes and voices, for example, the intensity of the sound may represent the inhalation and exhalation changes; or the different sound types represent the inhalation and exhalation. And let the user follow, for example, bird sounds, sea waves, different music tracks, etc.; or the user can be informed by voice to inhale or exhale, for example, when breathing instruction training is just started, The user's breathing mode can be guided through the "inhalation" and "exhalation" voice instructions that match the breathing pattern, and the user is informed that the user's breathing has been consistent with the desired mode of change. Maintain the current breathing rate, and stop the voice guidance of "inhalation" and "exhalation". Therefore, there are various options that can be varied depending on the actual implementation requirements, without limitation.

When the device according to the present invention is implemented as a combination with the earphone, the above-described auditory guidance will appear more natural, and since the sound and/or voice directly enters the ear via the earphone, it does not disturb the person around, so It also provides concealment so that breathing training can be carried out regardless of time and place. For example, breathing training can also be performed when riding a vehicle.

Moreover, when the tactile guidance method is employed, it is preferable to provide a change in vibration through a combination of components that are in contact with the user's body, for example, a wear structure, and the manner in which the vibration changes is also absent. Limitations, for example, can be implemented to use a vibration signal to alert the user to the correct exhalation and/or inspiratory start time point, or to only find the user's breathing pattern. When the deviation from the preset target guidance signal is too large, vibration guidance or the like is generated.

Here, it is advantageous that when the hearing and/or tactile guidance is adopted, the user can pry the eyes during the breathing guide training, which is more conducive to body relaxation and breathing adjustment.

In addition, in a preferred embodiment, the breathing guide signal can also be implemented to be output to the external device via the information providing unit and the wired/wireless transmission module, for example, a smart phone, a tablet computer, or a smart watch. And then, the external device provides the breathing guide signal to the user for breathing training.

In particular, in another preferred embodiment, the breathing guide signal is implemented to be generated by the external device and provided to the user. At this time, the external device further receives the relevant user from the information providing unit. Information on autonomic nervous activity, or breathing pattern, to provide the respiratory guidance signal to the user, or as a basis for adjusting the respiratory guidance signal, and the external device may further require Information about the breathing patterns of the relevant users received is stored as a reference for subsequent viewing of the records.

Furthermore, the wearable electrocardiographic detecting device according to the present invention may include other physiological sensors in addition to the electrocardiographic signal extraction and the above-mentioned electroencephalogram signal detection. Get other physiological signals on your body.

For example, there may be at least one photo sensor, where the photo sensor refers to a sensor having a light emitting element and a light receiving element and utilizing the principle of PPG (photoplethysmography) to obtain an optical signal, for example, utilizing The measure is performed in a penetrating manner or in a reflective manner, and the setting is also performed by the action of wearing the wearing structure, for example, on the surface on which the first electrode is located, thereby making it possible to wear the wearing structure. And being disposed on the user together with the first electrode, for example, near a finger, an ear or an ear, near a wrist, or Head and so on.

The light sensor is mainly used to detect the pulse generated by the heart beat, and the continuous pulse change obtained can obtain the user's heart rate sequence and be used for correlation analysis, since only a single light sensor is needed. The physiological signal can be obtained, and the setting is simple. The user only needs to wear the wearing structure to wear, so it is quite beneficial for continuous signal acquisition for long-term physiological state monitoring.

When the device of the present invention has the function of acquiring an electrocardiogram signal by using an electrode and acquiring a heart rate sequence by using a photo sensor, it is particularly advantageous for early warning and judgment of arrhythmia. This is because, despite complete heart rhythm information, for example, different types of arrhythmia, such as premature atrial contractions (PAC) occurring in the atria, and premature ventricular contractions occurring in the ventricle (Premature ventricular) Contractions, PVC), traditionally need to be judged by observing the electrocardiogram, but by observing changes in heart rate, you can still understand whether there are arrhythmia features, such as premature beats, ventricular fibrillation (AF, Atrial Fibrillation), various symptoms such as Tachycardia, Bradycardia, and Pause. Therefore, with the configuration of the present invention, it is possible to continuously obtain a heart rate sequence by using a photosensor for a long time. Pre-screening for arrhythmia may occur, and then, when arrhythmia may occur, the user is notified to perform an electrocardiogram to further confirm the correctness of the arrhythmia event and obtain further detailed information.

Therefore, in actual implementation, the user places the device on the body by the wearing structure, for example, on a finger, an ear, or a wrist. At this time, the light sensor on the wearing structure performs continuous pulse wave detection. And get the heart rate sequence, after which the acquired heart rate sequence will continue The ground is compared with the temporal characteristics of the possible events of the arrhythmia, and when a coincidence occurs, a possible event of arrhythmia is determined. At this time, the information providing unit notifies the user that a possible arrhythmia event has occurred, and reminds the user to perform the heart. The electrical signal is measured. Therefore, after receiving the notification, the user can easily obtain the ECG signal by touching the second electrode, and immediately obtain an ECG signal that may have arrhythmia. Here, the ECG signal can be directly analyzed to know whether there is arrhythmia symptom, and the result is notified to the user, or can be immediately transmitted to an external device, such as a mobile phone or a tablet, for storage and/or analysis. Etc., or, you can save it first, and then analyze it later, for example, download it to a computer for analysis, etc., without restriction.

In addition, the heart rate sequence obtained by the light sensor can also be used for continuous HRV analysis and breathing training as described above. Since the execution procedure is similar to the foregoing, the difference lies only in the HRV analysis and the breathing training. The physiological signal is the heart rate sequence obtained by the light sensor, so it will not be described again. Moreover, it can also cooperate with the acquisition of the EEG signal, and continuously perform the synchronization analysis between the respiratory, heart rate and EEG signals. To provide users with more information without increasing the burden.

Furthermore, when it is implemented to simultaneously obtain the electrocardiogram signal and the pulse, it is also possible to obtain the time required for the pulse wave to pass from the heart to the sensing position of the photo sensor, that is, the pulse transit time (Pulse Transit Time). , PTT), and because PTT is related to the arterial vessel hardness that affects blood pressure, the reference blood pressure value can be calculated through a specific relationship between PTT and blood pressure values.

In addition, similarly, the light sensor can be disposed in different positions, for example, when the two electrodes are disposed by the wearing structure, the light sensing can be separately set in the respective wearing structures. In this way, by calculating the time difference between the two pulse waves, the information about the Pulse Wave Velocity (PWV) can be obtained, and then the known The calculation theory can obtain the reference blood pressure value.

Alternatively, the blood pressure value can be directly obtained by using the cuff and the inflated pump, and in this case, the pulse pulse can be continuously changed through the cuff, thereby performing the analysis of the arrhythmia possible event as described above. Quite has an advantage.

Furthermore, the wearable electrocardiographic detecting device according to the present invention is also suitable for use during exercise, for example, the user can wear the device according to the present invention during exercise without feeling a burden and rest in the middle of exercise. The time is measured directly to know the effect of exercise on the heart. For example, the ECG can be obtained by touching the electrode by hand, or when the two wearing structures are directly worn, the ECG signal is directly obtained, or the light is configured. In the case of the sensor, the heart rate sequence and the like are obtained by the light sensor, whereby the information provided by the information providing unit can be known, for example, whether sufficient exercise intensity is reached (whether the heartbeat reaches the desired target), Whether the heart is abnormal or not, especially exercise is a good time for arrhythmia. Therefore, the electrocardiogram when arrhythmia occurs can be recorded immediately by the device of the present invention.

In addition, in addition to the intense exercise period, other time when the heartbeat abnormality may occur, for example, when climbing a mountain or flying a plane, it is also suitable to use the wearable electrocardiographic detecting device according to the present invention to more accurately grasp the heart condition of the heart. .

In summary, the wearable electrocardiographic detecting device according to the present invention has a device disposed on the user through the wearing structure, so that the contact between the electrocardiographic electrode and the skin is completed by the wearing action, thereby reducing the user's application. Force, and reduce the effect of myoelectric signal interference, especially when the two electrodes needed to obtain the ECG signal are placed on the user by wearing the structure, the interference of muscle tension is minimized. Moreover, whether it is wearing, wearing, wearing, and/or wearing, it is a common way of wearing in everyday life. It doesn't look awkward, it is more conducive to the user to wear on the body at any time, to record the physiological signal at any time when necessary, for example, to record the electrocardiogram when the arrhythmia occurs, and / or to obtain their own physiological information, For example, the results of real-time HRV analysis, and/or by physiological regulation, for example, breathing training, etc., are not only easy to configure, but also easy to use, and are widely used.

Furthermore, the wearable electrocardiographic detecting device according to the present invention also provides two modes of operation. In the first mode of operation, both electrodes are located on the surface of the device, and in the second mode of operation, one of the electrodes is transmissive. The connecting line extends out. Therefore, in addition to the user's selection of the operating mode depending on the use environment and operating habits, in the second operating mode, the extended electrodes are also provided in different body positions. The possibility of projecting an electrocardiogram at different angles, and because the extended electrode is disposed on the user through the wearing structure, further provides an operation mode that does not require active force of the user, and is quite advantageous.
