Description

Wearable physiological detection device

Technical Field

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

Background

An electrocardiographic detection device is known to be used for examining various heart diseases, for example, whether or not there is arrhythmia, myocardial hypertrophy or myocardial infarction due to hypertension or heart valve disease, or ischemic heart disease.

When people feel uncomfortable heart and go to hospitals for examination, the traditional electrocardiograph detection device, for example, the twelve-lead electrocardiograph detection, can detect various heart problems in detail, but if the source of the uncomfortable heart is occasional symptoms, for example, arrhythmia, the heart condition at the time of disease onset is probably not detected during the detection period, so that in response to the occasional symptoms, a manner of wearing a Holter electrocardiograph for long time detection, for example, wearing 24 hours to several days, is often adopted, it is desirable to record the electrocardiograph at the time of symptom occurrence, and similarly to the Holter electrocardiograph, an electrocardiograph recorder (ecgement recorder) is also used for a long time, but differently, the user determines the recording time by himself, for example, the heart feels uncomfortable, the electrocardiogram is recorded by button actuation, for example, the device does not record at all times, but records the electrocardiogram 30 seconds before and after the pressing time when the user presses the button. In addition to recording incidental symptoms, the holt-type electrocardiograph is also commonly used to monitor the heart after cardiac surgery or administration of therapeutic drugs to confirm the effectiveness of the treatment.

In either a hodt-type electrocardiograph or an electrocardiographic event recorder, a plurality of electrodes for obtaining an electrocardiogram must be attached to a user and connected to a device through a connecting wire, so that the user must always attach the electrodes and wear the device on the user during measurement, which is inconvenient, and skin discomfort is easily caused by attaching the electrodes for a long time, which is a cause of the user being lost, and in addition, there are cases where an electrocardiogram which is used for analyzing occasional symptoms is not recorded because of no morbidity even after long-time wearing detection. Moreover, such detection must be completed with the assistance of professional medical personnel, for example, the pasting of the electrodes must be completed in a hospital, and usually, after a long time of measurement is completed, a doctor downloads a recorded electrocardiogram for analysis, and it takes at least several days to know what heart is wrong, so the complexity is high, and the real-time performance is also poor.

Therefore, in view of the above disadvantages, a further improvement is proposed in a handheld electrocardiographic detection device, which solves the problem of having to wear the device on the body for a long time by using dry electrodes that do not need to be adhered to the body, and simplifies the complexity of performing detection. As disclosed in U.S. patent application nos. US7149571 and US7197351, a handheld electrocardiographic detection device has dry electrodes disposed on the surface of the device, which can perform electrocardiographic detection by touching the hand and/or the body surface whenever needed, and therefore, is not limited by the wearing time and the electrode adhesion, and thus can be used to monitor the heart more flexibly.

Then, with the popularization of portable electronic devices, such as smart phones, recently, there has appeared an electrocardiographic detection device combined with a mobile phone, as disclosed in US8615290, which is similar to a handheld electrocardiographic detection device and uses dry electrodes, and the difference is that the device is operated and controlled through an operation interface of the mobile phone, so that the number of devices to be carried on can be reduced for users who have a need to monitor the heart.

However, the above-mentioned electrocardiograph detection device, whether in a hand-held form or in a form combined with a mobile phone, can be carried about, but because it must be held by hand for operation, the size cannot be too small under the requirement of meeting ergonomics and the result needs to be displayed, and the carrying still has a certain burden; moreover, since the electrodes are not always disposed on the body, many steps are required to perform the detection, for example, the device is taken out and then turned on to start the detection, so that the detection time may be missed.

Furthermore, when the user wants to keep the hand stable and the muscle is tense or exert a special force to ensure the contact between the electrodes, the user is also likely to generate the electromyographic signals affecting the signal analysis by exerting a force.

Therefore, there is a need for a wearable electrocardiograph detection device, which can solve the above-mentioned drawbacks, and can be used more conveniently by a user while minimizing the influence of various uncertain factors during operation.

When the electrocardiograph detection device is worn on the body, other physiological information can be further obtained from the obtained electrocardiograph signal, for example, a time series of Heart beat intervals can be obtained from an electrocardiogram to perform HRV (Heart Rate Variability) analysis, so as to obtain the activity of the autonomic nerve, or information of relevant RSA (Respiratory Arrhythmia) can be obtained by analyzing the time series, so as to obtain the respiration variation used, and the user can be guided to perform Respiratory training that is helpful to improve the balance of the autonomic nerve by using the information.

Since one of the important causes of arrhythmia is autonomic nerve disorder, when a user wishes to record an electrocardiogram of the heart at the time of arrhythmia occurrence in real time by means of a wearable electrocardiographic detection device, it would be a more complete solution for the user if the same device could provide a function of improving the symptoms of arrhythmia.

Detailed Description

According to the utility model discloses a wearing formula electrocardio detection device, including a control module, a wearing structure, a first electrode and a second electrode, and an information provides the unit, wherein, this circuit system includes a treater, with controlling means's whole function, for example, via this first electrode and this second electrode and carry out electrocardiosignal's extraction etc. this wearing structure is used for setting up the device on one's body the user when carrying out electrocardiosignal and draw, in order to provide convenient to use nature, then be used for providing information to the user as for this information provides the unit, for example, operation relevant information, physiological information and analysis result etc..

Wherein, the circuit system can be implemented to be accommodated in the wearing structure, or, further, the device according to the present invention can further comprise a housing, at this time, the circuit system can be accommodated in the housing and/or the wearing structure, therefore, depending on the actual implementation situation, there is no limitation; the material of the housing may be the same as or different from the wearing structure, and for example, if the housing is made of the same material, the housing may be integrally formed, and if the housing is made of a different material, the housing may be made of a material suitable for the wearing position, and the housing is not limited.

In addition, since the electrocardiograph detecting device according to the present invention is implemented in a wearable form, the information providing unit can provide information in more options, including, but not limited to, visual, auditory, and tactile manners, 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 lamp number change; alternatively, the information providing unit may also be implemented as a sound module to provide information by way of voice or change in sound frequency or volume; alternatively, the information providing unit may be implemented as a vibration module, and provide information by using a variation manner such as intensity and length of vibration.

Furthermore, the information providing unit may be further implemented to output information to an external device through a wired transmission module or a wireless transmission module, so as 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, and the like, as long as the device is capable of providing the information to the user, and thus, there is no limitation.

In the wearable electrocardiographic detection device according to the present invention, particularly, the first electrode is implemented to be located on a surface that contacts the skin of the user when the entire electrocardiographic detection device is set on the user through the wearable structure, that is, the contact between the first electrode and the skin is realized by the action of setting the wearable structure on the user, and therefore, the first electrode can be brought into contact with the skin without the user applying force by himself, so that the myoelectric interference caused by muscle tension due to the operation action can be significantly reduced, which is very helpful for obtaining good signal quality.

The second electrode may be implemented on another surface of the device other than the surface, for example, the skin of a finger, a chest, etc., and the surface for disposing the first electrode and the other surface for disposing the second electrode may be any surface of the wearing structure or any surface of the shell, without limitation, it is only necessary to note that the first electrode and the second electrode do not contact the same portion of the skin of the user. Alternatively, it can be implemented to be disposed on the user through another wearing structure, so that the contact with the skin can be achieved by the active force of the wearing structure, and therefore, there is no limitation.

In view of the above, when using, this wearing structure of user accessible and will be according to the utility model discloses a wearing formula electrocardio detection device sets up on one's body, for example, on the finger, on the ear or on the wrist etc. and under this situation, the contact between this first electrode and skin has been realized promptly, then, when the demand of measuring the heart electrograph appears, only need again through the action with second electrode touching other part skins, draw electrocardio signal's return circuit can realize, the user can conveniently and easily gain the heart electrograph when having the needs at any time.

In addition, when the second electrode is also arranged on the user through the other wearing structure, the user only needs to arrange both wearing structures on the user, and the electrode arrangement for extracting the electrocardiosignal is completed, so that the user can press the starting key to extract the signal for a period of time, such as 30 seconds or 1 minute, when the user needs to record the electrocardiogram, or the user can also extract the electrocardiosignal and start recording and/or analyzing immediately after the device is worn on the user, so that the action of pressing the starting key to start measurement for recording the sudden heart condition is saved, and the method is not limited, and the appropriate mode can be selected according to the actual requirement.

Here, similarly, another shell may be combined with the another wearing structure, and the second electrode may also be implemented to be located on any surface of the another wearing structure or the another shell, as long as the second electrode can be in contact with the skin when the another wearing structure is disposed on the user, and therefore, there is no limitation.

Because the utility model discloses an electrocardio detection device adopts the form of wearing, consequently, the operation action of wearing on one's body, the start-up of device and/or electrocardio detection, except that general power and/or the mode of starting up the detection, still can have various selections, for example, can set up a switch near this second electrode, it can be triggered because of the application of force that second electrode and skin contact to make the device enter into the state that can carry out electrocardio signal extraction, in order to follow the start-up device and/or electrocardio detection; or, alternatively, the second electrode may be connected to a physical state detection unit to detect a physical change generated when the electrode contacts the skin, and the physical change is used to determine whether the contact between the electrode and the skin is stable enough, so as to determine whether the device can extract the electrocardiographic signal.

The physical state detecting unit may include a pressure sensing module for obtaining the pressure change and determining whether the electrode is pressed sufficiently, or may be implemented as a switch for obtaining the pressure applied to the electrode, or may include an impedance sensing circuit or a capacitance sensing circuit for obtaining the impedance and capacitance change of the electrode and determining whether the electrocardiographic detection is possible, and therefore, is not limited.

Therefore, when the switch is switched completely and/or the physical change does not conform to a preset range, the contact state between the second electrode and the skin is not enough for extracting the electrocardiosignals, so that the device is in a state that the extraction of the electrocardiosignals cannot be started, and when the switch is switched completely and/or the physical change conforms to a preset range, the contact between the second electrode and the skin is enough for extracting the electrocardiosignals, so that the device is converted into a state that the extraction of the electrocardiosignals can be started.

In particular, whether the electrode can be used or not, for example, whether the electrode is turned on or not, that is, the electrode is in an unusable state first, and the electrode is not turned on until the switch is completely switched or the physical change meets the preset range, so that the definition of the obtained electrocardiographic signal can be further ensured, and the accuracy of the analysis result is more favorable.

Furthermore, after determining that the ecg signal can be extracted, there are various options as to how to start the device and/or to perform the detection, for example, in a preferred embodiment, the device according to the present invention may be designed such that the device automatically starts to detect the ecg signal after a certain time, for example, 3 seconds; or in another preferred embodiment, the device is switched to the state in which the extraction of the ecg signal can be performed after a certain time, for example, after 3 seconds, and then the detection of the ecg signal is activated if the state in which the extraction can be performed is still continuous, so that there are various possibilities that may vary depending on the actual needs, without limitation.

In addition, with the above-mentioned starting and judging method, the device according to the present invention can also be implemented in a state of signal extraction, but only records when detecting the characteristic of the electrocardiographic signal, or adjusts the sampling frequency or the signal amplification factor, so as to record all possible electrocardiographic signal changes more completely.

The following is an example of a preferred embodiment of the wearable electrocardiograph detection device according to the present invention.

First, according to the concept of the first aspect of the present invention, the wearable structure is implemented as a finger-wearing structure, and therefore, the wearable electrocardiograph detection device according to the present invention is carried by the finger-wearing structure and is disposed on a finger of a user, and here, the wearable electrocardiograph detection device can be implemented in a manner that the finger-wearing structure accommodates the circuit system as shown in fig. 1A, or can also be implemented in a manner that the finger-wearing structure is combined with a housing 20 as shown in fig. 1B, and the circuit system can be accommodated in the housing and/or the finger-wearing structure, so that the wearable electrocardiograph detection device can be implemented according to practical implementation situations without limitation.

The first electrode 10 is located on a surface of the device that can be contacted with the skin of the finger due to wearing when the finger-worn structure is placed on the finger, and the second electrode 12 is located on another surface of the device other than the surface, for example, the surface may be the surface opposite to the surface or the surface adjacent to the surface, but it is only necessary to pay attention to the position that the skin of the finger is not contacted.

The main reason for selecting the finger as the position for setting the electrocardiograph detection device is that the finger wearing mode is a familiar use mode without learning again as wearing a ring for a common user, the contact between the first electrode and the skin can be completed by directly combining the finger wearing structure with the finger, and then when the electrocardiogram needs to be recorded at any time, the electrocardiograph signal can be immediately extracted by only contacting the second electrode with the skin of other parts except the limb where the finger is located. Moreover, the finger wearing structure applies force to the finger, the contact between the first electrode and the skin can be realized without the application of force of a user, and the influence of muscle tension on electrocardiosignals can be minimized.

There are many possibilities for practical operation, for example, the second electrode on the surface can be touched by another hand, as shown in fig. 2A, or other parts of the skin can be touched by moving the hand with the device, as shown in fig. 2B for operation of touching the ring to the cheek, and fig. 2C for electrocardiogram signal extraction for touching the ring to the torso, and therefore, there is no limitation.

Particularly, the finger-worn mode is adopted, so that the user can realize the electrocardio signal extracting circuit by moving the hand with the device to contact other parts of the body, more operation possibilities are brought, and the user can select a proper contact position according to different use environments and requirements, and the convenience is further improved.

Therefore, by such a concept, the user can conveniently obtain the electrocardiograms with different projection angles by contacting different positions, which is helpful for more accurately judging the heart condition, fig. 3 shows the contact position of the general twelve-lead electrocardiogram, and by the finger-wearing type electrocardio-detecting device according to the present invention, the user can conveniently wear the device on the left finger and obtain the electrocardiograms projection of the heart with different angles by contacting each measuring point from V1 to V6.

When the electrocardiogram is measured, an electrocardiogram with an angle can be obtained by every two electrodes, namely, the arrangement positions of the electrodes determine the projection angle of the electrical activity of the heart reflected by the electrocardiogram, and because the heart is three-dimensional and the heart part with pathological changes can be located at any heart position, for example, the examination of myocardial infarction needs to check whether ST drift caused by myocardial necrosis occurs in the electrocardiogram waveform or not, but the ST drift can not be detected at certain angles because of the position relationship of the ST drift, at the moment, the electrocardiogram with different angles needs to be examined, so that the obtaining of the electrocardiogram with different angles is greatly helpful for judging the heart diseases.

Here, the finger-worn structure according to the present invention is preferably disposed at a position on a finger, preferably at a knuckle where a proximal phalanx or a middle phalanx is located, so as to avoid falling off of the finger due to the position close to the end of the finger, for example, the finger-worn structure may be in the form of a general ring as shown in fig. 4A, or in the form of a shell worn on a flexible band surrounding the finger as shown in fig. 4B, or in the form of a flexible band only as shown in fig. 4C, or in the form of an open C-shaped ring without limitation; in any form, the ring may be implemented as a mechanism with variable ring circumference to adapt to the fingers of different wearers, and the band may be implemented as a mechanism with adjustable fixing position, for example, by arranging a fastening band to allow the user to select tightness of the ring, etc., and the implementation mode may also be varied according to actual situations without limitation; in addition, the form of the clip can be adopted to clip the knuckle or the fingertip, and the fixing effect can be achieved through the elasticity of the clip, which is also a good choice.

Furthermore, the finger stall may also be implemented as a finger stall disposed on the fingertip, as shown in fig. 4D, that is, a groove structure into which a finger can extend, for example, in the form of a ring or a concave hole, and the first electrode is disposed on the inner surface of the groove structure, and the inner surface is implemented to conform to the surface of the finger, so as to realize the contact between the first electrode and the skin of the finger when the finger extends. This configuration advantageously facilitates the operation of contacting different locations to obtain electrocardiograms of different projection angles. Therefore, the finger-worn electrocardiograph detection 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-worn structure through a connection line and disposed on the wrist of the limb where the finger is located through a wrist-worn structure, as shown in fig. 4E, so that the hardware configuration originally located near the finger and combined with the finger-worn structure, such as circuit, battery, etc., can be moved to the wrist to reduce the burden of the finger when wearing the device, and the wrist-worn structure and/or the surface of the housing not in contact with the wrist can also be used as the location for disposing the second electrode to provide another contact option for the user, or, as shown in fig. 4F, can be implemented as having housings on both the finger-worn structure and the wrist-worn structure, and therefore, there is no limitation.

Furthermore, in another preferred embodiment, the housing 20 can be combined with the finger-wearing structure through connectors, as shown in fig. 4G, in this case, the first electrode 10 contacts the right finger, and the second electrode 12 contacts the skin near the left wrist, and since the finger-wearing structure is placed against the wrist by being combined with the housing disposed on the wrist, when the user places both hands on a fixed surface, such as a table, for measurement, a very stable measurement posture can be formed, so that the generation of the electromyographic signals is minimized, and in addition, by the form of the connector connection, the loop of the electrocardiographic detection can be shortened, so that the electromagnetic interference noise in the environment induced by the connection wires can be minimized, and therefore, it is a very advantageous option.

Furthermore, according to another aspect of the present invention, the wearable structure is implemented as an ear wearing structure, so that the wearable electrocardiograph detection device of the present invention is carried by the ear wearing structure and is disposed on an ear of the user, and the circuit system is accommodated in the ear wearing structure and/or in a housing additionally included.

As shown in fig. 5A, the first electrode 10 is located on a surface of the device that can be contacted with the skin of the ear or the area near the ear due to wearing when the ear-worn structure is placed on the ear, and the second electrode 12 is located on another surface of the device other than the surface, for example, the surface opposite to the surface or the surface adjacent to the surface, but only needs to pay attention to the position where the skin of the ear or the area near the ear is not contacted. 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, such as noise from a power supply, and therefore, the implementation is not limited.

Here, the advantage of using the ear as the contact electrode is that the ear and its vicinity are regions with very small electromyographic signals, and the relative positional relationship between the ear and the head is relatively stable, so that even if the user moves his body during the measurement, for example, by slightly rotating his body or by rotating his neck, the contact between the electrode and the skin can be maintained stable without much interference affecting the measurement result.

In addition, in general daily life, compared with other body parts, the ears are parts which are less covered by clothes, and can be easily and directly contacted when needed, and moreover, the ears and the skin around the ears have the characteristic of less hairs, and the contact between the electrodes and the skin can be easily and freely realized, so that the ear-type electrode is quite convenient for a user to select.

Therefore, in practical operation, as shown in fig. 5B, the user can easily implement the electrical cardiac signal extracting circuit by touching the second electrode of the device worn on the ear with his/her hand, which is quite convenient.

In addition, in a preferred embodiment, the casing 20 can also be connected to the ear wearing structure through a connection line and disposed on a wrist through a wrist wearing structure, as shown in fig. 5C, so that hardware configurations originally located near the ear and combined with the ear wearing structure, such as circuits, batteries, etc., can be moved to the wrist to bear the ear when wearing the device, and the wrist wearing structure and/or the casing can also be used as a location for disposing the second electrode, such as a location for contacting another hand of the user or a location for contacting the wrist where the casing is located, so as to provide another contact option for the user, or can be implemented as having casings on both the ear wearing structure and the wrist wearing structure, as shown in fig. 5D, and therefore, there is no limitation.

Here, the implementation form of the ear wearing structure according to the present invention can have various options, for example, a common fixing manner in general daily life, such as the form of ear hook, ear plug, ear clip and the like shown in fig. 6A to 6C, so that the user does not need to learn again and can configure the ear wearing structure naturally, and therefore, the user can complete the electrode setting simply by wearing the ear wearing structure at ordinary times; moreover, when the electrodes are fixed on the ears by the fixing method, the contact between the electrodes and the skin can be realized without the force applied by the user, the interference of the electromyographic signals can be reduced to the minimum, and signals with good quality can be obtained.

In addition, particularly, in a preferred embodiment, the earwear structure is implemented to be attached to the ear by means of magnetic force, for example, two parts magnetically attracted to each other across the ear are utilized, and an electrode is disposed on one of the parts, and both parts can be implemented to be magnetic, or one part can have magnetic force and the other part can be attracted by magnetic force, without limitation; the magnetic force may be realized by arranging a magnetic substance inside the component or by directly manufacturing the component from the magnetic substance, and in addition, the substance attracted by the magnetic force may also be arranged inside the component or used for forming the component.

The position on the ear where the electrocardiographic signal is to be obtained is not limited, and may be any position of the ear itself, such as the inside of the ear canal, the earlobe, the inner and back surfaces of the auricle, e.g., the cavum concha, the area near the mouth of the ear canal, etc., the helix and the back surface of the auricle, and as shown in fig. 7, the area near the ear, e.g., the skin near the interface between the ear and the skull, etc., which are positions where the electrodes can be contacted to obtain the electrocardiographic signal.

In addition, because the position of setting up is the ear, consequently, according to the utility model discloses an ear-wearing electrocardio detection device also is very suitable for combining together with the earphone, for example, wired or wireless earphone, so, except can let electrocardio detection more integrate into daily life, also can exert bigger effect through the vocal function of earphone, for example, accessible sound and/or pronunciation and provide user's analysis result, for example, remind the electrocardio signal unusual to appear, or regularly remind the user to record the heart electrograph etc. more convenient.

It should be noted that both ears are selectable wearing positions, however, it is known through experiments that the contact position of the second electrode has a considerable influence on the signal quality, wherein when the second electrode is implemented to contact the left upper limb, the quality of the obtained electrocardiograph signal is far better than the signal obtained by contacting the right upper limb, therefore, when the electrocardiograph signal is measured by contacting the ears, the left upper limb is preferably contacted with the second electrode, so as to avoid the poor signal quality caused by contacting the right upper limb, and further to cause the erroneous judgment in the analysis.

Furthermore, in particular, according to another aspect of the present invention, the first electrode and the second electrode can be further configured to contact with the skin through the finger-wearing structure and the ear-wearing structure, as shown in fig. 8A-8B, so that the user can complete the electrode configuration required for measuring the electrocardiographic signal by wearing the wearing structures on the ear and the finger, and the contact between the two electrodes and the skin is achieved by actively applying force by the wearing structures, thereby minimizing the interference of the electromyographic signal caused by muscle tension.

Here, as shown in fig. 8A and 8B, the housing may be combined with only a single wearable structure, or both wearable structures may be provided with housings without limitation, and the circuit system may be accommodated in any wearable structure and housing without limitation, and may be changed according to actual requirements.

Besides the electrocardiograph electrodes on the finger-worn structure, the electrocardiograph electrodes on the ears can be matched with electrocardiograph electrodes on other positions to obtain electrocardiograph signals, such as the positions of the neck, the shoulders, the upper arms, the forearms and the like, for example, the electrocardiograph electrodes can be arranged on the neck and the vicinity of the shoulders through neck-worn structures such as neck rings and neck rings, and can also be arranged on the arms through arm-worn structures or wrist-worn structures, which is also quite convenient. Therefore, the electrode installation position capable of projecting the electrocardiogram is all the category of the present invention.

According to another aspect of the present invention, the wearable structure is implemented as a wrist-wearing structure, and the wearable electrocardiograph detection device according to the present invention is carried by the wrist-wearing structure and is disposed on a wrist of the user, and the circuit system is accommodated in the wrist-wearing structure and/or a housing further included therein.

As shown in fig. 9A, the first electrode 10 is located on a surface of the device that can be contacted with the skin near the wrist due to wearing when the wrist-worn structure is disposed on the wrist, and the second electrode 12 is located on another surface of the device other than the surface, for example, the surface may be a surface opposite to the surface or a surface adjacent to the surface, and only the position where the skin of the limb where the wrist is located is not contacted. 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, such as noise from a power supply, and therefore, the implementation is not limited.

The main reason for selecting the wrist as the location for installing the electrocardiograph detection device is that, as for a general user, the wrist wearing mode is familiar and needs no study again just like wearing a watch, the contact between the first electrode and the skin can be completed by directly combining the wrist wearing structure with the wrist, and then, when the electrocardiogram needs to be recorded at any time, the electrocardiograph signal can be immediately extracted by only contacting the second electrode with the skin of the other part except the limb where the finger is located, so that the operation process and the action are simple, natural and convenient. Moreover, the wrist is applied with force by the wrist wearing structure, the contact between the first electrode and the skin can be realized without the application of force by a user, and the influence of the muscle tension on the electrocardiosignals can be reduced to the minimum.

Therefore, in actual operation, as shown in fig. 9C, the user can easily realize the electrocardiographic signal extraction circuit by touching the second electrode with a hand, which is quite convenient. Besides the form of the wearing structure carrying the housing, the circuit can be accommodated in the wrist-worn structure as shown in fig. 9D, and therefore, there is no limitation.

Furthermore, in particular, according to another aspect of the present invention, as shown in fig. 9E-9F, the first electrode 10 and the second electrode 12 can be further implemented to be in contact with the skin through the wrist-wearing structure 90 and the finger-wearing structure 92, respectively, so that the user only needs to wear the wearing structures on the fingers and the wrist, respectively, to complete the electrode configuration required for measuring the electrocardiographic signal, which is quite convenient, and the contact between the two electrodes and the skin is achieved by the active force application of the wearing structures, and the user can achieve the contact with the electrodes without applying force, and in addition, if the user can place both hands on a fixed plane during the measurement, the interference of the electromyographic signal caused by the muscle tension can be minimized, which is quite advantageous.

In addition, in the embodiment shown in fig. 9E and 9F, a third electrode may be further disposed on a surface of the wrist wearing structure not contacting with the wrist skin, for example, the third electrode is disposed on the surface 94 or the surface 95 shown in fig. 9F, so that the user can still capture the electrocardiographic signal through the first electrode 10 and the third electrode without using the finger wearing structure, thereby providing another option for use.

Furthermore, the wrist-worn electrocardiograph detection device according to the present invention may further include a connection port 14, as shown in fig. 10A to 10C, for electrically connecting the third electrode 16 through a connection wire, where the third electrode may be further implemented to replace the function of the second electrode, for example, the second electrode may be disabled automatically when the third electrode is connected to the connection port, or the user may decide which electrode to start by himself through a switch, the implementation is not limited, and the third electrode 16 may also be implemented to contact the skin through a wearing structure, for example, an ear wearing structure (as shown in fig. 10B), a finger wearing structure (as shown in fig. 10C), or a wrist wearing structure.

Alternatively, the third electrode 16 can be connected by means of a connector, as shown in fig. 10D, in which case the first electrode 10 contacts the wrist of the user by wearing the wrist wearing structure, and the third electrode 16 is located in the finger wearing structure, in which case, since the finger wearing structure is combined with the device on the wrist by the connector, a relatively stable measuring posture can be realized, which further facilitates obtaining high-quality electrocardiographic signals.

When the third electrode is extended through the connection line as shown in fig. 10B-10C, the device of the present invention can provide more contact position options to obtain different cardiac projection electrocardiograms compared to the second electrode on the surface of the device, for example, when the cardiac projection angle of the second electrode is obtained through two hands (wearing the wrist of the wrist wearing structure and the hand contacting the second electrode), the third electrode can provide the option of obtaining different cardiac projection electrocardiograms by using the ear wearing structure to contact the ear (e.g., wearing the left hand of the wrist wearing structure and wearing the left ear of the ear wearing structure).

As described above, since a lesion-generating heart site may be located at any heart position, for example, examination of myocardial infarction requires to see whether ST drift due to myocardial necrosis occurs in an electrocardiographic waveform, but when the lesion-generating site is not detected at some angles, an electrocardiogram at different angles is necessary.

Therefore, the device of the present invention, by extending the third electrode, allows the user to measure the electrocardiographic signal by contacting the second electrode on the surface, and can obtain more information about the heart simply by reconnecting an electrode when the user needs to do so.

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

The utility model discloses in, the setting of second electrode lets the user can be very simply and rapidly when having the needs through the mode of touching surface electrode and gain electrocardiosignal, and the third electrode that extends then provides another selection that the user gained stable signal. When the third electrode is used, the third electrode is brought into contact with a part of the skin of the user's body by the wearing structure, so that factors such as muscle tension and hand movement which most easily affect the quality of the electrocardiographic signal can be eliminated, and a more stable and high-quality electrocardiographic signal can be obtained.

In addition, with respect to the hand touching the second electrode, the third electrode extending through the connection line as shown in fig. 10B-10C also allows the user to select a measurement position with a stronger cardiac electrical signal, for example, a position closer to the heart, so as to reduce the influence of the interference signal, for example, the myoelectrical signal with the same size can be excluded when the cardiac electrical signal is stronger, but the myoelectrical signal with the same size may be erroneously determined when the cardiac electrical signal is weaker because the myoelectrical signal cannot be distinguished from the cardiac electrical signal, so the user may set the third electrode at a position where the stronger cardiac electrical signal can be obtained, and the accuracy of the analysis result is further improved.

Therefore, according to the utility model discloses a wrist-worn electrocardio detection device has two kinds of operating modes, first operating mode and second operating mode, in this first operating mode, form first electrocardio signal extraction return circuit by this first electrode and this second electrode together, in order to gain first heart electrograph, and in this second operating mode, this first electrode and this third electrode form second electrocardio signal extraction return circuit together, and then gain second heart electrograph, and through the design of the operating mode that so chooses, even face different operating environment and use custom, all can get stable and high-quality electrocardio signal.

In addition to the wrist-worn ecg device, the finger-worn ecg device and the ear-worn ecg device according to the present invention can also be implemented to have a connection port to connect a third electrode instead of the second electrode.

For example, as shown in fig. 11A, the finger-worn electrocardiographic detection device may be connected to a finger-worn third electrode through a connection wire, and as shown in fig. 11B, the ear-worn electrocardiographic detection device may also be connected to a finger-worn third electrode through a connection wire, both of which allow the operation mode that the hand contacts the electrode to be replaced by a finger-worn structure that can provide active force application, so that unstable factors that may be generated due to the contact of the hand can be eliminated, which is helpful for obtaining more stable signals; in addition, as shown in fig. 11C, the finger-worn electrocardiograph detection device may be connected to an ear-worn third electrode, so that not only a measurement method without applying force is provided, but also an electrocardiogram of the heart projection angle different from that of the electrodes in contact with both hands is obtained. Therefore, there is no limitation.

Still further, according to the present invention, the wearable electrocardiograph detection device can also be implemented to obtain the first electrocardiogram through the first electrode and the second electrode, and obtain the second electrocardiogram through the first electrode and the third electrode, as shown in fig. 12A and 12B, that is, the first electrode forms an electrocardiograph detection loop with the second electrode and the third electrode when performing measurement, so that the user can select different operation modes according to different requirements to obtain the heart information closest to the self-requirement.

Furthermore, according to another aspect of the present invention, the wearable structure is implemented as a head-wearing structure, and therefore, the wearable electrocardiograph detection device of the present invention is carried by the head-wearing structure and is configured to be disposed on the head of the user, and the circuit system is accommodated in the head-wearing structure and/or in a housing that is otherwise included.

As shown in fig. 13, the first electrode is located on one surface of the device that can be contacted with the skin of the head due to wearing when the head-wearing 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 limbs (e.g., fingers, arms), neck, shoulders, etc., so as to achieve the cardiac signal capturing loop. It should be noted that the second electrode can be disposed at various positions, for example, on the surface opposite to the surface of the head-wearing structure or the surface adjacent to the surface, so as to be touched by the upper limb, or contact the skin of the upper limb through a finger-wearing structure, a wrist-wearing structure, or an arm-wearing structure; or, alternatively, an ear wearing structure capable of being fixed on the ear can be connected, and the second electrode is arranged on the exposed surface of the ear wearing structure so as to be contacted by the upper limb of the user; alternatively, the second electrode may be extended to the neck or shoulder via a connecting wire, for example, via a neck wearing structure such as a collar or necklace, so as to obtain the electrocardiographic signal. Thus, there may be various possibilities without limitation.

Here, the head-wearing structure may be implemented in various forms, such as a band, a head cover (head gear), or a hard head frame with an adjusting mechanism, or a glasses form, etc., with an emphasis on achieving contact of the electrodes with the skin, and thus, there is no limitation.

The head and the ear have similar characteristics, and electromyographic signals which can cause interference on the electrocardiosignals are not easy to generate, so the electroencephalogram detection device is also suitable for arranging the positions of the electrocardioelectrodes, and the electroencephalogram electrodes can be further arranged through the head wearing structure to obtain the electroencephalogram signals, for example, only at least two electroencephalogram electrodes are arranged on the inner side of the head wearing structure, or when the ear wearing structure is matched, one electroencephalogram electrode is respectively arranged on the inner sides of the head wearing structure and the ear wearing structure to contact electroencephalogram signal sampling points on the head, for example, common sampling points comprise Fp1, Fp2, O1, O2, A1, A2 and the like, or any position defined according to a 10-20 system, so that more detection functions can be provided for a user under the condition of hardly increasing load, and the electroencephalogram detection device has great advantages.

Moreover, the electrocardio-electrode, i.e. the first electrode, which is arranged on the head-wearing structure and is used for contacting the skin of the head can be further shared as an electroencephalogram electrode, and forms an electrocardio-signal acquisition circuit with the second electrode and forms an electroencephalogram acquisition circuit with another electroencephalogram electrode.

Alternatively, the sharing may be implemented by using two electrodes to obtain the ecg signal and the eeg signal simultaneously, i.e. the ecg signal and the eeg signal are obtained through the same physiological signal acquisition circuit, which is performed because the ecg signal is much larger than the eeg signal, wherein the ecg signal is in the mV (millivolt) range, and the eeg signal is in the mV (μ V) range, so that the two signals can be distinguished from each other even though entering the same input terminal of the physiological signal acquisition circuit.

In practice, for example, one electrode contacting the head and the hand may be used in conjunction with another electrode capable of contacting the head and the hand simultaneously to obtain an electrocardiographic signal and an electroencephalogram signal, wherein the electrode contacting the head and the hand simultaneously, taking the most common metal electrode plate as an example, may be implemented such that two electrode plates contacting the hand and the head are electrically connected to each other, or may be implemented such that two portions of one electrode plate contact the hand and the head respectively, for example, when the electrode is disposed on the head-mounted structure, the skin of the head and the skin of the outside hand are contacted at the inner side, and thus, the implementation form is not limited.

Accordingly, the electroencephalogram electrodes are also suitable for placement on the ear-worn structures of fig. 5-6 and 8. Firstly, there is the position that can detect cerebral cortex activity in ear and ear near region, for example, temporal lobe area (temporal lobe), moreover, in the brain electricity detection field, the ear is because structure and position all with head phase separation, be difficult for receiving the influence of brain activity, so always be regarded as one of the best position of setting up the reference electrode, so, combine reference electrode in wearing the structure and contact with the ear, originally be common when the brain electricity detects, consequently, according to the utility model discloses an ear wear formula electrocardio detection device is last also be fairly suitable for combining and sets up brain electricity electrode to obtain brain electricity signal, and also with the mode that is equally suitable for adopting shared electrode, namely, implement first electrode simultaneously as brain electricity electrode.

Furthermore, in the embodiments of fig. 5-6 and 8, in addition to the two electroencephalogram electrodes being disposed on the ear-wearing structure, a head-wearing structure may be further connected to dispose an electroencephalogram electrode therein, so that electroencephalogram signals can be obtained through the electroencephalogram electrodes disposed on the head-wearing structure and the ear-wearing structure, respectively, and electrocardiosignals can be obtained through the electrocardio electrodes disposed in the ear-wearing structure in cooperation with the electrocardio electrodes disposed on the exposed surface of the ear-wearing structure (fig. 5-6) or the electrocardio electrodes disposed on the finger-wearing structure (fig. 8), thereby providing various possible implementation options.

In practical use, according to the utility model discloses an electrocardio detection device is owing to adopt the design of wearing the form, consequently provides the possibility of conveniently obtaining electrocardiosignal in succession during wearing, also consequently provides more convenient functions of user.

First, since the wearable device can be worn on the body of a user without any burden, the wearable device is suitable for use in daily life, for example, the user can wear the wearable device on the ear, finger or wrist in daily life, and can start electrocardiographic signal detection in real time or periodically perform electrocardiographic detection every day to effectively grasp the heart changes of the user when the user needs the device at any time, for example, when the user feels that the heart is uncomfortable.

In particular, the occurrence of arrhythmia is often without warning, so that the electrocardiogram detecting device worn on the body can record the electrocardiogram when arrhythmia occurs or the electrocardiogram when the user feels irregular heartbeat in real time, so as to be used as a basis for the doctor to judge whether arrhythmia occurs.

For example, no matter what the form of the electrocardiographic detection device is worn by fingers, ears or wrists, the user can obtain the electrocardiograph in real time by touching the second electrode with hands when feeling uncomfortable or trying to record the electrocardiograph, as shown in fig. 2A, 5B and 9C; alternatively, in the case where the second electrode is provided on the body by the wearing structure or the third electrode is used, since both electrodes for obtaining the electrocardiographic signal are already in contact, the user can record the electrocardiographic signal in real time by simply starting the electrocardiographic signal measurement, for example, by pressing the start key. In any case, the use is simple and convenient.

Here, the apparatus according to the present invention may be set to automatically record an electrocardiogram for a fixed time, for example, 30 seconds or 1 minute, after the electrocardiographic measurement is started, so that the user can easily record the electrocardiogram when the heart feels discomfort, for example, when arrhythmia occurs, in real time.

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

For example, information of a continuous Heart Rate sequence can be obtained from a continuous electrocardiogram to perform an HRV (Heart Rate Variability) analysis. HRV analysis is the most important method for observing autonomic nervous activity, and the results of the HRV analysis can provide detailed understanding of autonomic nervous activity, such as activity of sympathetic nerves, activity of parasympathetic nerves, equilibrium of autonomic nerves, and the magnitude of the activity of autonomic nerves, and there have been more and more studies showing that many diseases, such as headache, gastrointestinal discomfort, hypertension, insomnia, depression, etc., may be caused by autonomic nervous dysfunction. Therefore, the change of autonomic nervous activity during daily work and rest can be known from the results of long-term continuous HRV analysis, and further, it is possible to investigate whether the behavior or emotion in daily life causes autonomic nervous dysfunction, whether the above-mentioned diseases are caused by autonomic nervous dysfunction, and the like.

Moreover, because according to the utility model discloses a form is dressed in the adoption of the device, consequently, through this information providing unit, still can provide the user with real-time HRV analysis's result, consequently, the user just can learn in real time which action or mood probably cause autonomic nerve unbalance, and further, through the utility model discloses such design, the user still can carry out psychosomatic adjustment in real time, for example, relaxes the mind and body, and learns whether autonomic nerve consequently resumes to comparatively harmonious state.

In addition, when the electrocardiogram apparatus is used in a sleep period, the HRV analysis of the continuous electrocardiogram during the sleep period can also be used to understand the physiological changes during the sleep period, for example, the sleep period can be determined, the sleep quality can be understood, and the like, thereby being convenient.

It should be noted that, after obtaining the ecg signal, the device according to the present invention can be implemented to store the ecg signal first, and output the ecg signal for further processing after the measurement is finished, for example, to a computer for storage and analysis; and/or, since the device of the present invention has the information providing unit, it can also provide the user with the related information or analysis result in real time, such as the average heart rate, the HRV analysis result, etc., and/or the information providing unit can also be implemented to transmit the recorded electrocardiosignal and/or data to an external device, such as a mobile phone, a tablet computer, etc., in real time, and the external device displays and/or analyzes the electrocardiosignal and/or data in real time, and therefore, there is no limitation.

Furthermore, according to the utility model discloses a wearing formula electrocardio detection device also provides the way that lets the user can carry on the breathing training with oneself. By wearing on the body, the device according to the present invention can obtain continuous ecg signals and time series of heart beat intervals, i.e. heart rate series, and by analyzing the heart rate series, information of Relevant Sinus Arrhythmia (RSA) can be obtained, so-called RSA means a phenomenon that the heart beat changes due to the influence of respiration on the autonomic nervous system in the case where the heart rate is controlled by the autonomic nerve, generally speaking, the heart beat is accelerated during inspiration, and the heart beat is slowed down during respiration, so that the change pattern of respiration and the activity of the autonomic nerve can be known by observing RSA.

In addition, since respiration is a physiological activity that is controlled by autonomic nerves and influenced by consciousness, it is possible to influence autonomic nerves by consciously adjusting the respiration, so as to achieve a physical and mental relaxation effect, wherein studies have shown that the respiration rate (respiration rate), the tidal volume, and the expiratory/inspiratory ratio are factors that influence the activities of sympathetic and parasympathetic nerves, wherein a slower rate decreases the activity of the sympathetic nerves, and a faster rate increases the activity of the sympathetic nerves, for example, the respiration rate of a typical adult falls within a range of about 10 to 18 times per minute, when the respiration rate decreases to a range of 5 to 8 times per minute, it is helpful to increase the activity of the parasympathetic nerves, and when the expiratory/inspiratory ratio increases, that is, when there is a longer expiratory period relative to the inspiratory period, parasympathetic activity can also be enhanced.

Therefore, generally speaking, breathing training is performed by providing a user with a breathing guidance that helps relax the mind and body, for example, the breathing guidance provides a breathing rate that falls within 5-8 breaths per minute that reduces sympathetic activity and/or, in the case of natural breathing, increases expiratory phase to guide the user to reduce the breathing rate and/or increase expiratory phase, thereby increasing parasympathetic activity, suppressing sympathetic nerves, and allowing the body to relax from a stressed state.

Furthermore, since the autonomic imbalance is also one of the important causes of arrhythmia, when one of the purposes of the user using the device is to record the electrocardiogram of arrhythmia in real time, the device of the present invention provides a breath guidance training function to help the user to improve the arrhythmia by controlling the breath to change the balance of autonomic nerves, and the two are complementary and more significant.

When utilizing according to the utility model discloses a wearing formula electrocardio detection device and when breathing the training, the user only needs to dress the device on one's body, and maintain two electrodes and skin between the contact can, and during breathing the training, this information provides the unit then is used for providing the user with breathing guide signal, so that the user follows the adjustment and breathes, in addition, this information provides the unit and also can provide the physiological state change of relevant user during breathing the training, for example, sympathetic nerve and burden sympathetic nerve's activity change, the change of rhythm of the heart, and the change of actual breathing mode etc. in order to carry out the reference of breathing the training as the user.

Here, since the time for performing the respiratory training is longer, 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, by using the second electrode disposed through the wearing structure, or by using the third electrode to perform the cardiac signal extraction in cooperation with the first electrode, so as to perform the respiratory training in a more relaxed manner.

In addition, the respiration guiding signal can also be a dynamic guiding signal which is used for adjusting according to a respiration change mode obtained by the heart rate sequence, namely, the respiration condition of the user is obtained in real time to know the respiration rate and/or whether the respiration rate falls in a rate range which is beneficial to relaxing the body and mind, and the guiding signal is dynamically adjusted, so that the user can achieve the effect of respiration guiding training in the easiest and most comfortable way.

Or, because increasing the amplitude of RSA helps trigger relaxation response (relaxation response) and release the accumulated pressure, so as to achieve the effect of increasing the ratio of parasympathetic/sympathetic activity, the user can start inhaling by observing the heart rate variation pattern of the user and informing the user to start exhaling by guidance when the heart rate starts accelerating, and can start exhaling by guidance when the heart rate starts slowing down, so as to achieve the effect of increasing the amplitude of RSA and achieve the purpose of relaxing the body and mind.

Furthermore, it can be known whether the respiration and the heart rate are harmonious and synchronous through the result of the frequency domain analysis of the heart rate sequence, and the better harmonious and synchronous between the respiration and the heart rate represents a more orderly and harmonious heart rhythm, i.e. the human body is in a more relaxed and steady state, so that when the user obtains relevant information during training, the physiological state of the user can be changed through consciousness.

In addition, when the electroencephalogram electrodes are matched to obtain the electroencephalogram signals, the heart rate, the respiration and the synchronization (synchronization) among the electroencephalogram signals can be observed, and the physiological state of the user can be known. Since, according to research, exhalation and inhalation cause blood volume fluctuation in blood vessels, and the fluctuation also reaches the brain along with the blood flow, and further causes brain waves to fluctuate in a low frequency region, for example, below 0.5 hz, the breathing pattern can also be known by observing the brain waves, and furthermore, since the sinoatrial node and the vascular system of the heart are also regulated by the autonomic nervous system, and the autonomic nervous system also feeds changes in heart rate and blood pressure back to the brain through the baroreceptor system (baroreceptor system), and further affects the function and operation of the brain, for example, the cerebral cortex, and can be measured by EEG, there is a relationship of influence between them, and good synchronism between them can represent that the human body is in a more relaxed state, which is quite useful information.

For example, the information providing unit may provide information related to the heart rate in real time while providing the respiration guidance signal, and/or obtain information related to the synchronization between the respiration and the heart rate through spectrum calculation, so that the user may know in real time the influence of respiration adjustment on the autonomic nerve, such as whether the activity of the parasympathetic nerve is enhanced or whether the activity of the sympathetic nerve is reduced, and thus, the physiological feedback procedure performed by using the respiration guidance signal may be more efficient.

In addition, the user can further know the effect of the breathing training through the HRV analysis result, for example, the HRV analysis can be respectively executed before and after the breathing training, so as to know the influence of the breathing training on the autonomic nerve, even, the real-time HRV analysis can be implemented, the information providing unit can be used for enabling the user to know the activity situation of the autonomic nerve in real time, and the user can know the physiological condition of the user in real time in a manner similar to physiological feedback, so that the physical and mental relaxation effect is further facilitated.

Since the HRV analysis is performed on a heart rate sequence over a period of time, the real-time HRV analysis can be performed by Moving a time Window (Moving Window) concept, i.e. a calculation time segment is determined, for example, 1 minute or 2 minutes, and then, by continuously Moving the time segment backward, for example, every 5 seconds, the HRV analysis result can be continuously obtained, for example, every 5 seconds, so as to achieve the purpose of providing the real-time HRV analysis result.

The information providing unit may have various options in providing the breathing guidance signal, for example, guidance may be performed in a visual, auditory, and/or tactile manner, without limitation. The selection of visual guidance includes, but is not limited to, graphical changes, text display, changes in light intensity, and/or changes in light signal, etc., which are suitable, for example, to guide the user to inhale and exhale on the display element by using patterns conforming to the breathing change pattern; or the number of the LED lamps changes to represent inspiration and expiration; or the user can be informed directly by using characters to inhale and exhale.

In addition, when using auditory guidance, the selection includes, but is not limited to, sound changes and speech, for example, the strength of sound can represent inhalation and exhalation changes; or different sound types represent inspiration and expiration, so that the user can follow the sound, such as a bird, a sea wave, different music tracks and the like; alternatively, the user may be informed of the inspiration or expiration by voice, for example, when the breathing guidance training is just started, the user may be guided through the voice instructions "inspiration" and "expiration" that match the breathing variation pattern, and when it is detected that the user's breathing matches the desired variation pattern, the user is informed of the voice guidance "continue to maintain the current inspiration and expiration rate" and stop "inspiration" and "expiration". Therefore, there are various options, which can be varied according to the requirements of the actual implementation without limitation.

When the device according to the present invention is implemented in combination with an earphone, the auditory guidance is more natural, and sound and/or voice directly enters the ear through the earphone, so that the user is not disturbed, and the concealment is further provided, so that the breathing training can be performed without being limited by time and place, for example, the breathing training can be performed while riding a vehicle, which is more convenient.

Furthermore, when the tactile guidance is adopted, it is preferable to provide the vibration variation in a form combined with a member contacting with the user's body, such as a wearing structure, and the vibration variation is also not limited, and for example, it may be implemented by using a vibration signal to remind the user of a correct expiration and/or inspiration start time point, or generating vibration guidance only when the user's breathing pattern is found to deviate too much from a preset target guidance signal, or the like.

Here, it is advantageous that, when the auditory and/or tactile guidance is used, the user can close both eyes during the breathing guidance training, which is more helpful for the relaxation of the body and the adjustment of breathing.

In addition, in a preferred embodiment, the respiration guiding signal can also be implemented to be outputted to the external device, such as a smart phone, a tablet computer, a smart watch, etc., via the information providing unit and the wired/wireless transmission module, and then the external device provides the respiration guiding signal to the user for the user to perform the respiration training.

In particular, in another preferred embodiment, the respiration guidance signal is generated and provided to the user by the external device, and the external device further receives information related to the autonomic nervous activity or the respiration pattern of the user from the information providing unit, and provides the information to the user at the same time of providing the respiration guidance signal, or is used as a basis for adjusting the respiration guidance signal, and the external device may further store the information related to the respiration pattern of the user to be received, and the information is used as a reference for later viewing the record.

Furthermore, according to the utility model discloses a wearing formula electrocardio detection device except can carrying out electrocardio signal's extraction to and the above-mentioned EEG signal detection mentioned, also can include other physiological sensor to obtain other physiological signal when dressing on one's body.

For example, the sensor may include at least one light sensor, where the light sensor includes a light emitting element and a light receiving element, and obtains a light signal by using a ppg (photoplethysmography) principle, for example, a person who measures the light signal by using a penetrating method or a reflecting method, and the light sensor is also set by the action of wearing a wearing structure, for example, the light sensor may be located on a surface where the first electrode is located, so that the light sensor may be set on the user body, for example, near a finger, an ear or an ear, near a wrist or a head, and the like, together with the first electrode by the action of wearing the wearing structure.

The optical sensor mainly aims to detect the pulse generated by the heart beat, and the heart rate sequence of the user can be obtained through the obtained continuous pulse change, and the heart rate sequence is used for carrying out related analysis.

When the utility model discloses a device has the function that utilizes the electrode to gain electrocardiosignal and utilize light sensor to gain the rhythm of the heart sequence simultaneously, will be favorable to arrhythmia's early warning and judgement very much. This is because, although complete arrhythmia information, for example, different types of arrhythmia such as Premature Atrial Contractions (PACs) occurring in the atria and Premature Ventricular Contractions (PVCs) occurring in the ventricles, conventionally needs to be determined by observing the electrocardiogram, by observing the change in the heart rate, it is possible to interpret the characteristics of arrhythmia, such as Premature contractions (prematurity Beats), ventricular Fibrillation (AF), tachycardias (tachycardias), bradycardias (bradycardias), and cardiac pauses (Pause), and so on, and therefore, with the configuration of the present invention, it is possible to obtain a cardiac rhythm sequence continuously for a long time by using the optical sensor to previously screen whether an arrhythmia is likely, and then, when an arrhythmia is likely, notify the arrhythmia user of cardiac rhythm detection, to further confirm the correctness of the possible event of arrhythmia and to obtain further detailed information.

Therefore, in practical implementation, the user sets the device on the body, for example, on a finger, an ear or a wrist, through the wearing structure, at this time, the optical sensor on the wearing structure performs continuous pulse wave detection and obtains a heart rate sequence, then the obtained heart rate sequence is continuously compared with the time characteristics of the arrhythmia possibility event, and when the heart rate sequence matches with the time characteristics of the arrhythmia possibility event, the arrhythmia possibility event is determined, at this time, the information providing unit notifies the user that the arrhythmia possibility event occurs through the information providing unit, and reminds the user to measure the electrocardiosignal, so that after the user receives the notification, the user can simply contact the second electrode to extract the electrocardiosignal, and immediately obtain the electrocardiosignal with the arrhythmia possibility. Here, the ecg signal may be directly analyzed to determine whether the arrhythmia symptom occurs, and the result is notified to the user, or may be transmitted to an external device, such as a mobile phone or a tablet computer, for storage and/or analysis, or may be stored in advance and analyzed later, such as being downloaded to a computer for analysis, without limitation.

In addition, the heart rate sequence obtained by the optical sensor can also be used for performing continuous HRV analysis and respiratory training as described above, and the execution procedure is similar to that described above, and the difference is only that the physiological signal for performing HRV analysis and respiratory training is the heart rate sequence obtained by the optical sensor, so that the details are not repeated; furthermore, the synchronization analysis among the respiration, the heart rate and the electroencephalogram signal can be continuously performed in coordination with the acquisition of the electroencephalogram signal, so that more information can be provided for the user without increasing the burden.

Further, when the electrocardiographic signal and the Pulse wave are acquired at the same Time, the Time required for the Pulse wave to travel from the heart to the sensing position of the photosensor, that is, the so-called Pulse Transit Time (PTT) can be obtained, and since PTT is related to the hardness of arterial blood vessels that affect the blood pressure level, the reference blood pressure value can be calculated from a specific relationship between PTT and the blood pressure value.

Similarly, the optical sensors may be disposed at different positions, for example, when both electrodes are disposed through the wearing structure, the optical sensors may be disposed in the wearing structures separately, so that the information about the propagation Velocity (PWV) of the Pulse Wave can be obtained by calculating the time difference between the two Pulse waves, and the reference blood pressure value can be obtained by a known calculation theory.

Alternatively, it is also advantageous to use a tourniquet and an inflation pump to directly obtain the blood pressure, and in this case, it is also possible to obtain the continuous pulse variation through the tourniquet, so as to perform the analysis of the arrhythmia event as described above.

Furthermore, the wearable ECG 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 directly during the time of rest in the middle of the exercise to know the effect of the exercise on the heart, e.g., the electrocardiogram can be obtained by touching the electrodes with hands, or the electrocardiogram signal can be directly obtained when the two wearing structures are directly worn, or the heart rate sequence can be obtained by the optical sensor under the condition of arranging the optical sensor, it is thus known, on the basis of the information provided by the information providing unit, whether, for example, a sufficient exercise intensity has been reached (whether the heartbeat has reached the intended target), or whether the heart is abnormal or not, especially the exercise is the good sending time of arrhythmia, therefore, the device of the utility model can also record the electrocardiogram when arrhythmia happens in real time.

In addition, except during the violent exercise period, other times that the heartbeat is abnormal may appear, for example, when climbing mountain, taking the aircraft, also be fit for using according to the utility model discloses a wearing formula electrocardio detection device to grasp self heart situation more in real time.

In summary, according to the wearable electrocardiograph detection device of the present invention, the wearable electrocardiograph detection device is disposed on the body of the user through the wearable structure, so that the contact between the electrocardiograph electrodes and the skin is completed through the wearing action, thereby achieving the effects of reducing the force applied by the user and reducing the interference of the electromyographic signals, and especially, when two electrodes required for obtaining the electrocardiograph signals are disposed on the body of the user through the wearable structure, the interference of the muscle tension is minimized; moreover, no matter the mode of wearing by fingers, ears, wrists and/or heads is a common wearing mode in ordinary daily life, the wearing mode is not obtrusive in use, and the wearing mode is more beneficial for a user to wear on the body at ordinary times so as to record physiological signals at any time when necessary, for example, recording an electrocardiogram and the like when arrhythmia occurs, and/or obtaining physiological information of the user, for example, real-time HRV analysis results, and/or performing physiological regulation and control by using the physiological signals, for example, performing respiratory training and the like, therefore, the wearing mode is easy to configure, convenient to use and wide in application.

Furthermore, according to the utility model discloses a wearing formula electrocardio detection device also provides two kinds of mode of operation, in first mode of operation, two electrodes all are located the surface of device, and in second mode of operation, one of them electrode extends through the connecting wire, consequently, except that the user can let according to service environment and operation habit different and select the mode of operation, in second mode of operation, the electrode that extends also provides and sets up in different health positions and gain the possibility of different angle projection electrocardiograms, and, because this electrode that extends sets up on the user through wearing the structure, the event also further provides the mode of operation that need not the user's initiative application of force, has the advantage rather.
