Technical Field

[0001] The present application relates to a biofeedback device using an electrocardiogram and a control method thereof. Background Art

[0002] Figure 1 This is a diagram for explaining conventional biofeedback.

[0003] refer to Figure 1 Biofeedback is a technique that uses special equipment to measure physical and mental reactions, and feeds back the measured information to the patient in a perceptible form in the form of sound, light or graphics, thereby training the patient to self-regulate his or her own state of relaxation or tension.

[0004] Biofeedback therapy refers to a type of training that allows one to accurately recognize the changing state of one's own physiological activities and the ability to control their changes while confirming various involuntary physiological activities such as blood pressure, heart rate, skin temperature, muscle tension, breathing, and skin conductance, which are regulated by the autonomic nervous system. This biofeedback technique is used as a treatment method to relieve pain, relieve stress, stabilize the mind, and promote overall health.

[0005] Generally speaking, in existing biofeedback, while a user is sitting or lying steadily in a specific space equipped with a biofeedback device, electrodes (or sensors) for measuring the user's physiological reactions (biosignals) are attached to the user's body, and the physiological reactions are confirmed based on the responses of the signals applied to the corresponding electrodes, thereby performing biofeedback therapy.

[0006] However, if Figure 1 As shown, this conventional biofeedback technology is limited in space when using the technology, and has a complex structure due to multiple wires connected to the electrodes, so there is the inconvenience of limiting the movement / operation of the user.

[0007] The background art of the present application is disclosed in Korean Patent No. 10-1990383. Summary of the invention

[0010] However, the technical problems to be solved by the embodiments of the present application are not limited to the above-mentioned technical problems, and there may also be other technical problems.

[0011] Technical Solution

[0012] As a technical solution for achieving the technical problem, a biofeedback device using an electrocardiogram in one embodiment of the present invention includes: a signal acquisition unit, which acquires an electrocardiogram signal of a user from an electrocardiograph; an analysis unit, which analyzes the acquired electrocardiogram signal and provides a diagnosis result of the user's state as an analysis result; and a control unit, which controls at least one stimulation unit among a plurality of stimulation units to control the user's state according to the diagnosis result of the state, and provides stimulation corresponding to the at least one stimulation unit to the user under the control of the control unit.

[0015] Furthermore, the analysis unit determines whether the suspected abnormal electrocardiogram signal is an abnormal electrocardiogram signal by comparing the similarity between the waveform data of a plurality of abnormal electrocardiogram signals stored in the database and the waveform data of the suspected abnormal electrocardiogram signal, thereby providing the state diagnosis result.

[0016] Moreover, the analysis unit can determine the user's heart rate by analyzing the electrocardiogram signal, and the control unit can differently control the stimulation provision type of the stimulation provided by the at least one stimulation unit according to the determined heart rate. When the heart rate meets the preset standard, the control unit controls to change the stimulation provision type of the stimulation provided by the at least one stimulation unit from a first stimulation provision type to a second stimulation provision type.

[0017] Moreover, the odor stimulation unit may include: a plurality of fragrance storage parts for storing a plurality of types of fragrance substances; and a nozzle part connected to the plurality of fragrance storage parts for spraying a fragrance substance stored in the plurality of fragrance storage parts under the control of the control part.

[0018] Moreover, when the heart rate meets the preset standard, the control unit controls the nozzle unit to spray the fragrance substance stored in one of the multiple fragrance storage units; when the heart rate does not meet the preset standard, the control unit controls the nozzle unit to spray the fragrance substance stored in a fragrance storage unit among the multiple fragrance storage units that is different from the one fragrance storage unit.

[0019] In addition, according to an embodiment of the present application, a control method for a biofeedback device using an electrocardiogram may include: a step in which a signal acquisition unit acquires an electrocardiogram signal of a user from an electrocardiograph; a step in which an analysis unit analyzes the acquired electrocardiogram signal and provides a state diagnosis result of the user as an analysis result; and a step in which a control unit controls at least one stimulation unit among a plurality of stimulation units based on the state diagnosis result to perform biofeedback to control the state of the user, and the control step provides stimulation corresponding to the at least one stimulation unit to the user.

[0045] Figure 2 is a schematic structural diagram of a biofeedback system 1000 using an electrocardiogram according to an embodiment of the present application, Figure 3 is a structural block diagram of a biofeedback device 100 using an electrocardiogram according to an embodiment of the present application.

[0046] Hereinafter, for the convenience of description, the biofeedback system 1000 using an electrocardiogram according to an embodiment of the present application is referred to as the present system 1000 , and the biofeedback device 100 using an electrocardiogram according to an embodiment of the present application is referred to as the present device 100 .

[0047] refer to Figure 2 and Figure 3 , the system 1000 may include the device 100 and the user terminal 20.

[0048] The present device 100 can obtain the electrocardiogram signal of the user 3 from the electrocardiograph 10 included in the present device 100, and control at least one stimulation unit among the multiple stimulation units 60 included in the present device 100 based on the analysis result of the obtained electrocardiogram signal (in other words, it can be expressed as a status diagnosis result).

[0049] As an example, the device 100 may provide the status diagnosis result to the user terminal 20 through the control unit 50. As an example, for example, the operation of the device 100 may be controlled by the user terminal 20 (ie, remotely controlled).

[0050] The device 100 and the user terminal 20 can send and receive data (information) via the network.

[0051] As an example of a network for sharing information between the present device 100 and the user terminal 20, it can include a 3GPP (3rd Generation Partnership Project) network, an LTE (Long Term Evolution) network, a 5G network, a WIMAX (World Interoperability for Microwave Access) network, a wireless network (Internet), a LAN (Local Area Network), a Wireless LAN (Wireless Local Area Network), a WAN (Wide Area Network), a PAN (Personal Area Network), a Bluetooth network, a WiFi network, an NFC (Near Field Communication) network, a satellite broadcasting network, an analog broadcasting network, a DMB (Digital Multimedia Broadcasting) network, etc., but is not limited to these.

[0052] The user terminal 20 may refer to a device (apparatus) linked to the present apparatus 100 through a network. The user terminal 20 may include all types of wireless communication devices such as PCS (Personal Communication System), GSM (Global System for Mobile Communication), PDC (Personal Digital Cellular), PHS (Personal Handyphone System), PDA (Personal Digital Assistant), IMT (International Mobile Telecommunication)-2000, CDMA (Code Division Multiple Access)-2000, W-CDMA (W-Code Division Multiple Access), Wibro (Wireless Broadband Internet) terminal, smart phone (Smartphone), smart pad (Smart Pad), tablet PC (tablet PC), wearable device, desktop computer, etc., but is not limited thereto.

[0053] The device 100 may be provided in a patch type that can be attached to a part of the body of the user 3, a wearable type that can be worn on a part of the body of the user 3 (for example, a watch that can be worn on the wrist of the user), or a type that can be built into various products, but is not limited thereto. Here, various products may be, for example, yoga items, massage chairs, car steering wheels, etc.

[0054] The device 100 may include: an electrocardiograph 10 , a signal acquisition unit 30 , an analysis unit 40 , a control unit 50 , and a plurality of stimulation units 60 .

[0055] As an example, the electrocardiograph 10 may be provided in a form built in the present device 100. That is, the present device 100 may include the electrocardiograph 10.

[0056] In one example of the present application, a configuration is described in which the electrocardiograph 10 is included in the present device 100 (that is, a configuration in which the electrocardiograph 10 is built into the present device), but the present invention is not limited thereto.

[0057] As another example, the electrocardiograph 10 may be provided as a separate component from the present apparatus 100. In this way, when the electrocardiograph 10 and the present apparatus 100 are provided as separate structures from each other, the present apparatus 100 may obtain the electrocardiograph signal measured (sensed) by the electrocardiograph 10 from the electrocardiograph 10 by wireless communication via a network.

[0058] The electrocardiograph 10 can measure an electrocardiogram (ECG) signal of the user 3 and provide the measured ECG signal to the signal acquisition unit 30 .

[0059] The signal acquisition unit 30 may acquire the electrocardiogram signal of the user 3 from the electrocardiograph 10 via wired or wireless communication. In the present application, as an example, the user 3 may be a patient, but is not limited thereto.

[0060] The analysis unit 40 can analyze the electrocardiogram signal acquired by the signal acquisition unit 30, and provide the state diagnosis result of the user 3 as the analysis result. Here, the state diagnosis result may include whether it is normal / abnormal related to the heart state, etc., but is not limited thereto. The state diagnosis result may also include the data of the electrocardiogram signal obtained from the signal acquisition unit 30.

[0061] Here, the normal heart state can be expressed differently as the user's health state is a stable state, and the abnormal heart state can be expressed differently as the user's health state is an unstable state.

[0062] That is, the analysis unit 40 analyzes the electrocardiogram signal acquired by the signal acquisition unit 30, thereby determining (analyzing) whether the heart state of the user 3 is normal (i.e., the health state is a stable state) or abnormal (i.e., whether the health state is an unstable state) as a state diagnosis result.

[0063] When there is a waveform satisfying the preset characteristic condition in the waveform of the electrocardiogram signal acquired by the signal acquisition unit 30, the analysis unit 40 can preliminarily determine that the signal corresponding to the waveform satisfying the preset characteristic condition is a suspected abnormal electrocardiogram signal. Here, the preset characteristic condition can represent a condition in which a signal belonging to a threshold range has a characteristic during a preset time period.

[0064] In other words, the analysis unit 40 can preliminarily determine whether a suspected abnormal electrocardiogram signal has occurred based on whether there is a waveform of a signal within a threshold range during a preset time period in the waveform of the electrocardiogram signal acquired by the electrocardiograph 10. Figure 4 Here, the threshold range, as an example, may refer to a range set with respect to the amplitude of the waveform of the electrocardiogram signal acquired from the electrocardiograph 10 .

[0065] Figure 41 is a diagram showing an example of a waveform of an electrocardiogram signal acquired (measured) by the electrocardiograph 10 in the biofeedback device 100 using an electrocardiogram according to an embodiment of the present application.

[0066] Figure 4 The waveforms of the electrocardiogram signal obtained (measured) by the electrocardiograph 10 shown include a waveform S1 that does not meet the preset characteristic conditions, i.e., the waveform S1 of a normal electrocardiogram signal, and a waveform S2 that meets the preset characteristic conditions, i.e., the waveform S2 of a suspected abnormal electrocardiogram signal suspected to be an abnormal electrocardiogram signal.

[0067] refer to Figure 4 , the analysis unit 40 can determine whether there is (occurs) a waveform S2 that satisfies the characteristic (waveform characteristic) of the signal occurrence preset time t that belongs to the threshold range r in the waveform of the electrocardiograph signal obtained from the electrocardiograph 10. At this time, if there is a waveform S2 that satisfies the preset characteristic condition, the analysis unit 40 can preliminarily determine the signal (electrical signal) corresponding to the waveform S2 that satisfies the preset characteristic condition as a suspected abnormal electrocardiogram signal, which may be an abnormal electrocardiogram signal caused by the poor heart condition of the user 3.

[0068] In other words, if there is a waveform S2 in the acquired ECG signal waveform that belongs to the threshold range r and occurs at a preset time t, the analysis unit 140 can preliminarily determine that the signal corresponding to the waveform, that is, the signal corresponding to the waveform S2 that meets the preset characteristic condition, is a suspected abnormal ECG signal, and the suspected abnormal ECG signal may be an abnormal ECG signal. Figure 4 The signal corresponding to waveform S2 in the middle A interval is preliminarily judged to be a suspected abnormal electrocardiogram signal.

[0069] Here, the threshold range r may represent a preset range relative to the value of the electrocardiogram signal (or the value of the electrical signal of the electrocardiogram signal) measured (acquired) by the electrocardiograph 10. Figure 4 The case where the electric signal of the electrocardiogram signal acquired from the electrocardiograph 10 is a voltage signal is shown. In this case, the threshold range r can be set to a range of not less than the first voltage value and not more than the second voltage value.

[0070] Therefore, when an electrical signal having a voltage value greater than the first voltage value and less than the second voltage value in the electrocardiogram signal acquired from the electrocardiograph 10 occurs for a preset time t, the analysis unit 40 can preliminarily determine the signal as a suspected abnormal electrocardiogram signal.

[0071] Accordingly, when the electrocardiogram signal (electrical signal) obtained from the electrocardiograph 10 generates a signal of waveform S2 that meets the preset characteristic conditions, the analysis unit 40 does not immediately judge the signal corresponding to the waveform S2 as an abnormal electrocardiogram signal, but can preliminarily (temporarily) judge it as a suspected abnormal electrocardiogram signal, which may be an abnormal electrocardiogram signal.

[0072] After initially determining that the electrocardiogram signal is suspected to be abnormal, the analysis unit 40 can make a second determination (i.e., a final determination) as to whether the electrocardiogram signal is abnormal by comparing the waveform data of a plurality of abnormal electrocardiogram signals stored in a database (not shown) with the waveform data of the suspected abnormal electrocardiogram signal. The analysis unit 40 can provide a state diagnosis result based on the second determination result.

[0073] Specifically, the analysis unit 40 can compare the similarity between each of the waveform data of the plurality of abnormal electrocardiogram signals stored in the database (not shown) and the waveform data of the previously preliminarily determined suspected abnormal electrocardiogram signal. Through the similarity comparison, the analysis unit 40 can determine whether there is waveform data of an abnormal electrocardiogram signal whose similarity with the waveform data of the suspected abnormal electrocardiogram signal exceeds a threshold similarity among the waveform data of the plurality of abnormal electrocardiogram signals.

[0074] At this time, if there is at least one waveform data of an abnormal electrocardiogram signal whose similarity exceeds the threshold similarity among the waveform data of the multiple abnormal electrocardiogram signals, the analysis unit 40 can finally determine for the second time that the waveform data of the suspected abnormal electrocardiogram signal is the waveform data of the actual abnormal electrocardiogram signal. Through the second judgment, the analysis unit 40 can finally determine (analyze) that an abnormal electrocardiogram signal has occurred in the electrocardiogram signal obtained from the electrocardiograph 10.

[0075] That is, regarding the waveform data of the suspected abnormal electrocardiogram signal that has been preliminarily judged, when, through similarity comparison, there is at least one waveform data of an abnormal electrocardiogram signal whose similarity exceeds the threshold similarity in the database (not shown), the analysis unit 40 can judge the suspected abnormal electrocardiogram signal that has been preliminarily judged as an abnormal electrocardiogram signal for the second time (finally).

[0076] refer to Figure 5 , the description of the similarity calculation process can be more easily understood.

[0077] Figure 5 The following is a process for explaining how the analysis unit 40 of the biofeedback device 100 using an electrocardiogram calculates (calculates) the similarity between the waveform data of a suspected abnormal electrocardiogram signal and the waveform data of an abnormal electrocardiogram signal according to an embodiment of the present application.

[0078] Figure 5As an example, S2 shows an example of waveform data of the suspected abnormal electrocardiogram signal (i.e., suspected abnormal electrocardiogram signal) determined initially above. In addition, D1 is waveform data of one abnormal electrocardiogram signal (i.e., one abnormal electrocardiogram signal) among waveform data of multiple abnormal electrocardiogram signals stored in a database (not shown), and as an example, an example of waveform data of a first abnormal electrocardiogram signal (i.e., a first abnormal electrocardiogram signal) is shown.

[0079] In the following, for the convenience of explanation, S2 is set as a suspected abnormal electrocardiogram signal, and D1 is set as a first abnormal electrocardiogram signal. In addition, the value of the first abnormal electrocardiogram signal D1 (the value of the electrical signal corresponding to the first abnormal electrocardiogram signal) can be expressed differently as a standard value. In this case, even if the description of the first abnormal electrocardiogram signal D1 is omitted below, it can also be applied to the description of each of the multiple abnormal electrocardiogram signals stored in the database (not shown).

[0080] In addition, D1a represents an upper limit value obtained by adding a preset error range value (e.g., e%) to a standard value, and D1b represents a lower limit value obtained by subtracting a preset error range value (e%) from a standard value. Here, a range R above the lower limit value D1b and below the upper limit value D1a may be referred to as an allowable range (allowable error range). In other words, the allowable range R (allowable error range) may represent a range in which the value of an electrical signal (for example, a voltage value) falls within a range above the lower limit value D1b and below the upper limit value D1a.

[0081] refer to Figure 5 The analyzing section 40 may compare (ie, calculate) the similarity between the first abnormal electrocardiogram signal D1 and the suspected abnormal electrocardiogram signal S2 of any one of the waveform data of a plurality of abnormal electrocardiogram signals stored in a database (not shown).

[0082] In order to compare the similarity, the analysis unit 40 may obtain the values ​​of the electrical signals of a preset number (e.g., 100) of sampling points P from the suspected abnormal electrocardiogram signal S2. For example, for 100 sampling points P on the suspected abnormal electrocardiogram signal S2, the analysis unit 40 may obtain the value of the electrical signal corresponding to each of the 100 sampling points.

[0083] Here, the positions of the preset number of sampling points on the suspected abnormal electrocardiogram signal S2 can be determined at positions where the distances between the sampling points are spaced apart from each other at the same interval relative to the length of time (i.e., the preset time, t) corresponding to the suspected abnormal electrocardiogram signal S2. That is, the preset number of sampling points can be determined at positions spaced apart from each other at the same interval.

[0084] The preset number of sampling points P may include a first sampling point P1 located within the allowable range R, and a second sampling point P2 located outside the allowable range R. That is, the first sampling point P1 may represent a point located within a range above the lower limit value D1b and below the upper limit value D1a. The second sampling point P2 may represent a point located within a range less than the lower limit value D1b or within a range exceeding the upper limit value D1a.

[0085] The analysis unit 40 may calculate the number of first sampling points P1 within the allowable range and the number of second sampling points P2 outside the allowable range among the preset number of sampling points P. The analysis unit 40 may calculate the similarity between the first abnormal electrocardiogram signal D1 and the suspected abnormal electrocardiogram signal S2 using the ratio between the number of first sampling points P1 and the number of second sampling points P2.

[0086] The analyzing section 40 may calculate the similarity (similarity value) between the first abnormal electrocardiogram signal D1 and the suspected abnormal electrocardiogram signal S2 using the following formula 1.

[0087] [Mathematical formula 1]

[0088] S(%)=N1 / N×100%

[0089] Here, S(%) represents the similarity (similarity value) between the first abnormal ECG signal D1 and the suspected abnormal ECG signal S2, N1 represents the number of first sampling points P1 within the allowable range, and N represents the number of second sampling points P2 outside the allowable range.

[0090] As an example, when the number of first sampling points P1 among 100 sampling points P is 90 and the number of second sampling points P2 is 10, the similarity (similarity value) between the first abnormal electrocardiogram signal D1 and the suspected abnormal electrocardiogram signal S2 may be 90%.

[0091] Thus, the analysis unit 40 can compare the similarity between the plurality of abnormal electrocardiogram signals (i.e., waveform data of the plurality of electrocardiogram signals) stored in the database (not shown) and the suspected abnormal electrocardiogram signal S2 (waveform data diagram of the suspected abnormal electrocardiogram signal). In other words, the analysis unit 40 can calculate the similarity between each of the plurality of abnormal electrocardiogram signals and the suspected abnormal electrocardiogram signal S2.

[0092] According to the similarity comparison (calculation) result, if there is at least one abnormal ECG signal among the multiple abnormal ECG signals whose similarity with the suspected abnormal ECG signal S2 exceeds the threshold similarity, the analysis unit 40 can determine for the second time that the suspected abnormal ECG signal S2 is an abnormal ECG signal. If it is determined that the suspected abnormal ECG signal S2 is an abnormal ECG signal, the analysis unit 40 can finally determine that an abnormal ECG signal has occurred in the ECG signal obtained from the electrocardiograph 10. Here, the threshold similarity is a value that serves as a reference for identifying whether the suspected abnormal ECG signal is an abnormal ECG signal, and can represent a threshold value for the similarity calculated by the mathematical formula 1. As an example, the threshold similarity can be set to 98%, but is not limited thereto.

[0093] In other words, in order to determine whether waveform data matching the waveform data of the suspected abnormal electrocardiogram signal S2 exists among the waveform data of multiple abnormal electrocardiogram signals stored in a database (not shown), the analysis unit 40 may perform a matching comparison between the waveform data of the suspected abnormal electrocardiogram signal S2 and the waveform data of multiple abnormal electrocardiogram signals stored in a database (not shown).

[0094] At this time, if there is at least one waveform data of an abnormal ECG signal that matches the waveform data of the suspected abnormal ECG signal S2 among the waveform data of multiple abnormal ECG signals stored in the database (database), the analysis unit 40 will secondarily judge the suspected abnormal ECG signal S2 that has been preliminarily judged to be a second abnormal ECG signal, thereby ultimately judging that the ECG signal of user 3 is abnormal (i.e., judging that an abnormal ECG signal has occurred in the ECG signal obtained from the electrocardiograph).

[0095] Here, the waveform data of the abnormal ECG signal that matches the waveform data of the suspected abnormal ECG signal S2 can represent the waveform data of the abnormal ECG signal that matches the waveform of the suspected abnormal ECG signal S2 100%, but is not limited to this. As described above, it can represent the waveform data of the abnormal ECG signal that belongs to a preset similarity range (i.e., the similarity exceeds the threshold similarity).

[0096] If the second judgment is that the suspected abnormal ECG signal determined initially is an abnormal ECG signal, the analysis unit 40 can know that the current heart state of the user 3 is abnormal (that is, the user's health state is unstable), and provide a status diagnosis result indicating that the current heart state of the user 3 is abnormal.

[0097] The control unit 50 can control at least one stimulation unit among the plurality of stimulation units 60 based on the state diagnosis result provided by the analysis unit 40, so as to control (adjust, control) the state of the user 3. Through the control of the control unit 50, stimulation corresponding to at least one stimulation unit controlled by the control unit 50 can be provided to the user 3.

[0098] As an example, when the analysis unit 40 provides a state diagnosis result indicating that the heart state of the user 3 is in a "normal" state, the control unit 50 may control at least one of the plurality of stimulation units 60 to provide stimulation of a first stimulation provision type. On the other hand, when the analysis unit 40 provides a state diagnosis result indicating that the heart state of the user 3 is in an "abnormal" state, the control unit 50 may control at least one of the plurality of stimulation units 60 to provide stimulation of a second stimulation provision type.

[0099] In this case, the second stimulation provision type may indicate a type in which the stimulation intensity is relatively stronger or the stimulation time is relatively longer than the first stimulation provision type. A specific example thereof can be more easily understood through the following description.

[0100] A plurality of stimulation units 60 may be provided in a form built into the present device 100 (biofeedback device using electrocardiogram).

[0101] The multiple stimulation units 60 may include at least two of: a vibration stimulation unit 61 capable of providing vibration stimulation, a sound stimulation unit 62 capable of providing sound stimulation, a light stimulation unit 63 capable of providing light stimulation, and an odor stimulation unit 64 capable of providing odor stimulation.

[0102] Furthermore, the analysis section 40 may determine the heart rate of the user 3 by analyzing the electrocardiogram signal acquired from the electrocardiograph 10 .

[0103] The control section 50 may differently control the stimulation providing type of stimulation provided by the at least one stimulation unit in consideration of the heart rate determined at the analysis section 40 (or based on the heart rate, in synchronization with the heart rate).

[0104] Here, the stimulation providing type may include at least one of stimulation intensity, stimulation time, and stimulation pattern.

[0105] As a specific example, the control unit 50 may control at least one of the vibration intensity, the vibration time, and the vibration pattern as the stimulation provision type of the vibration stimulation provided by the vibration stimulation unit 61. The control unit 50 may control at least one of the sound intensity (magnitude), the sound emission time, and the sound emission pattern as the stimulation provision type of the sound stimulation provided by the sound stimulation unit 62. The control unit 50 may control at least one of the light intensity (magnitude), the light emission time, and the light emission pattern as the stimulation provision type of the light stimulation provided by the light stimulation unit 63. The control unit 50 may control at least one of the odor intensity (the amount of odor emitted), the odor emission time, and the odor emission pattern as the stimulation provision type of the odor stimulation provided by the odor stimulation unit 64.

[0106] When the heart rate determined by the analysis section 40 satisfies a preset standard, the control section 50 may control to change the stimulation provision type of stimulation provided by at least one stimulation unit among the plurality of stimulation units 60 from the first stimulation provision type to the second stimulation provision type.

[0107] For example, the control unit 50 controls the stimulation (vibration stimulation) provided by the vibration stimulation unit 61 as at least one stimulation unit differently according to the determined heart rate as follows. That is, the control unit 50 controls the stimulation (vibration stimulation) provided by the vibration stimulation unit 61 differently according to the heart rate as follows.

[0108] When the determined heart rate is 100 beats per minute, the control unit 50 may control the operation of the vibration stimulation unit 61 so that the vibration stimulation unit 61 vibrates 100 times per minute (generating vibration stimulation) at the fifth stage of vibration intensity among the five stages of vibration intensity (here, the first stage may be the lightest intensity and the fifth stage may be the strongest intensity) according to the heart rate. As another example, when the determined heart rate is 70 beats per minute, the control unit 50 may control the operation of the vibration stimulation unit 61 so that the vibration stimulation unit 61 vibrates 70 times per minute (generating vibration stimulation) at the second stage of vibration intensity among the five stages of vibration intensity according to the heart rate.

[0109] In one example of the present application, it is shown that controlling at least one stimulation unit according to the heart rate (synchronous) means only controlling at least one stimulation unit so that the number of stimulations generated corresponds to the number of heartbeats, but it is not limited thereto. As another example, it can be shown that when the present invention controls at least one stimulation unit according to the heart rate, at least one stimulation unit is controlled so that the number of stimulations generated corresponds to the number of times set in proportion to the heart rate.

[0110] Exemplarily, it is assumed that the number of times set in proportion to the heart rate is 1 / 2. In this case, when the determined heart rate is 100 beats per minute, the control unit 50 can control the action of the vibration stimulation unit 61 so that the vibration stimulation unit 61 vibrates 50 times per minute according to the heart rate at the fifth stage of vibration intensity among the five stages of vibration intensity (i.e., 1 / 2 of the total 100 times, i.e., 50 times). As another example, when the determined heart rate is 70 beats per minute, the control unit 50 can control the action of the vibration stimulation unit 61 so that the vibration stimulation unit 61 vibrates 35 times per minute according to the heart rate at the second stage of vibration intensity among the five stages of vibration intensity (i.e., half of the total 70 times, i.e., 35 times).

[0111] As another example, the control unit 50 controls the stimulation providing type (odor stimulation) provided by the odor stimulation unit 64 as at least one stimulation unit differently according to the determined heart rate as follows. At this time, it is assumed that the number of times set in proportion to the heart rate is 1 / 50. Here, the number of times set in proportion to the heart rate can be input and set by the user according to the type of stimulation (that is, according to which stimulation among vibration, sound, light, and odor stimulation).

[0112] For example, when the judged heart rate is 100 beats per minute, the control unit 50 can control the operation of the odor stimulation unit 64 so that the odor stimulation unit 64 generates an odor (aroma) with an odor intensity of the fifth stage twice (1 / 50 of 100 times, i.e. 2 times) per minute (i.e., generates odor stimulation) according to the heart rate in the odor intensity (odor emission) divided into 5 stages (at this time, the first stage can represent the situation when the amount of odor emitted is the least and the intensity is the weakest, and the fifth stage can represent the situation when the amount of odor emitted is the largest and the intensity is the strongest).

[0113] In this way, the control section 50 can differently control the stimulation providing type of at least one stimulation unit among the plurality of stimulation units 60 in consideration of the heart rate determined by the analysis section 40 (according to the heart rate).

[0114] In addition, when the heart rate meets the preset standard, the control unit 50 controls the stimulation type provided by at least one stimulation unit to change from the first stimulation type to the second stimulation type. Here, the second stimulation type may refer to a type that is set to have a relatively strong stimulation intensity or a relatively long stimulation time compared to the first stimulation type.

[0115] In addition, the preset standard may refer to a standard set as a preset threshold value, or may also refer to a standard set in a plurality of preset range intervals.

[0116] Exemplarily, the preset threshold value is set as the preset standard, assuming that it is set to "80 times or more per minute".

[0117] When the heart rate of the user 3 analyzed by the analysis unit 40 is less than 80 beats per minute, the control unit 50 may control the stimulation provision type of the vibration stimulation of the vibration stimulation unit 61 as at least one stimulation unit with the first stimulation provision type. On the other hand, when the heart rate of the user 3 analyzed by the analysis unit 40 is more than 80 beats per minute (preset threshold), the control unit 50 may control the stimulation provision type of the vibration stimulation unit 61 to change from the first stimulation provision type to the second stimulation provision type.

[0118] Here, as an example, the first stimulation providing type may indicate a type of generating vibration stimulation having a second level of vibration intensity for 20 seconds, and the second stimulation providing type may indicate a type of generating vibration stimulation having a fifth level of vibration intensity for 40 seconds.

[0119] As another example, when the heart rate of the user 3 analyzed by the analysis unit 40 is less than 80 beats per minute, the control unit 50 may control the stimulation provision type of the sound stimulation of the sound stimulation unit 62 as at least one stimulation unit with the first stimulation provision type. On the other hand, when the heart rate of the user 3 analyzed by the analysis unit 40 is more than 80 beats per minute, the control unit 50 may control the stimulation provision type of the sound stimulation unit 62 to change from the first stimulation provision type to the second stimulation provision type.

[0120] Here, as an example, the first stimulation providing type may represent a type of generating a sound having a second stage of sound intensity (magnitude) for 20 seconds, and the second stimulation providing type may represent a type of generating a vibration stimulation having a fifth stage of sound intensity (magnitude) for 40 seconds.

[0121] In addition, exemplarily, as a preset standard, a standard for multiple preset range intervals is set, assuming that the first range interval is set to "less than 70 times per minute", the second range interval is set to "more than 70 times and less than 80 times per minute", the third range interval is set to "more than 80 times and less than 90 times per minute", and the fourth range interval is set to "more than 90 times per minute".

[0122] At this time, when the heart rate belongs to the condition of the first range interval among the multiple range intervals, the control section 50 can control the stimulation providing type of the vibration stimulation of the vibration stimulation unit 61 as at least one stimulation unit with the first stimulation providing type. In addition, when the heart rate belongs to the condition of the second range interval, the control section 50 can control the stimulation providing type of the vibration stimulation unit 61 with the second stimulation providing type, and when the heart rate belongs to the condition of the third range interval, the stimulation providing type of the vibration stimulation unit 61 can be controlled with the third stimulation providing type. In addition, when the heart rate belongs to the condition of the fourth range interval, the control section 50 can control the stimulation providing type of the vibration stimulation unit 61 with the fourth stimulation providing type.

[0123] Here, from the first stimulation provision type to the fourth stimulation provision type, the stimulation intensity may be set to gradually become stronger, and the stimulation time may be set to gradually become longer.

[0124] For example, when the heart rate falls within the first range, the control unit 50 may control the vibration stimulation unit 61 to provide the first stimulation type and generate the first stage of vibration intensity for 10 seconds. Furthermore, when the heart rate falls within the second range, the control unit 50 may control the vibration stimulation unit 61 to provide the second stimulation type and generate the second stage of vibration intensity for 20 seconds.

[0125] In addition, when the heart rate falls within the third range, the control unit 50 can control the vibration stimulation unit 61 to provide the third stimulation type to produce the third stage of vibration intensity for 30 seconds. In addition, when the heart rate falls within the fourth range, the control unit 50 can control the vibration stimulation unit 61 to provide the fourth stimulation type to produce the fourth stage of vibration intensity for 40 seconds.

[0126] In this way, the control unit 50 can consider the standard set as a preset threshold as a preset standard for control, so that when the heart rate of the user 3 analyzed by the analysis unit 40 is above the preset threshold, the stimulation providing type of the stimulation providing unit provided by at least one stimulation unit among the multiple stimulation units 60 can be changed from the first stimulation providing type to the second stimulation providing type.

[0127] In addition, the control unit 50 can consider controlling the standards related to multiple range intervals as preset standards, so that according to the heart rate level of the user 3 analyzed by the analysis unit 40, the stimulation providing type provided by the stimulation providing unit from at least one stimulation unit among the multiple stimulation units 60 is changed differently according to each of the multiple range intervals.

[0128] On the one hand, the odor stimulation unit 64 may include a plurality of aroma storages for storing various types of aroma substances. In addition, the odor stimulation unit 64 may include a nozzle portion, which is connected to the plurality of aroma storages and, under the control of the control unit 50, sprays any aroma substance stored in the plurality of aroma storages.

[0129] Exemplarily, it is assumed that the odor stimulation unit 64 includes three aroma storage parts as the plurality of aroma storage parts. In this case, the odor stimulation unit 64 may include: a first aroma storage part for storing a first aroma substance, a second aroma storage part for storing a second aroma substance, and a third aroma storage part for storing a third aroma substance. In addition, the odor stimulation unit 64 is connected to the first aroma storage part, the second aroma storage part, and the third aroma storage part, and selectively sprays one of the plurality of aroma substances (for example, the first aroma substance, the second aroma substance, and the third aroma substance).

[0130] In one example of the present application, the nozzle part is illustrated as a component connected to all of the plurality of fragrance storage parts, but it is not limited thereto, and the nozzle part may be provided with a plurality of nozzle parts so as to be connected to the plurality of fragrance storage parts respectively. That is, as another example, the odor stimulation unit 64 may include: a first nozzle part connected to the first fragrance storage part, a second nozzle part connected to the second fragrance storage part, and a third nozzle part connected to the third fragrance storage part.

[0131] In this case, the aroma substance stored in each of the plurality of aroma storage parts may be in the form of liquid, gas, solid, etc., but is not limited thereto.

[0132] Exemplarily, the first fragrance substance may be a known lavender fragrance-related substance, which can relieve stress, palpitations, headaches, etc., and contribute to physical and mental stability. The second fragrance substance may be a known strawberry fragrance-related substance, which has the effect of significantly relieving tension and anxiety and stably regulating emotions. The third fragrance substance is a known grapefruit flavor-related substance, which has a variety of positive effects on the body and mind, such as relieving stress, eliminating depression, eliminating edema, migraines, and enhancing liver function. However, these examples of fragrances are merely examples to help understand the present disclosure, and are not limited thereto. The fragrance substances stored in each of the plurality of fragrance storage units may store substances related to various fragrances.

[0133] When the heart rate determined by the analysis unit 40 satisfies the preset standard, the control unit 50 may control the operation of the nozzle unit so as to spray the aroma substance stored in one of the plurality of aroma storage units. On the other hand, when the heart rate determined by the analysis unit 40 does not satisfy the preset standard, the control unit 50 may control the operation of the nozzle unit so as to spray the aroma substance stored in a different aroma storage unit from the one of the plurality of aroma storage units.

[0134] For example, when the determined heart rate satisfies the condition of "more than 80 times per minute" as a preset standard, the control unit 50 may control the action of the nozzle unit so as to spray a first aroma substance stored in one of the plurality of aroma storage units, namely, a first aroma storage unit. On the other hand, when the determined heart rate does not satisfy the condition of "more than 80 times per minute" as a preset standard (i.e., less than 80 times per minute), the control unit 50 controls the action of the nozzle unit so as to spray a second aroma substance stored in another aroma storage unit, namely, a second aroma storage unit, among the plurality of aroma storage units, which is different from the first aroma storage unit.

[0135] In this way, the control unit 50 controls the nozzle unit to selectively spray any one of the multiple fragrance substances stored in the multiple fragrance storage units according to whether the judged heart rate meets the preset standard (or according to the level of the heart rate), thereby providing different fragrances to the user 3 according to the user's heart rate state.

[0136] In addition, in the present device 100, a plurality of fragrance storage parts are replaceably provided in the odor stimulation unit 64. By replacing, the present device 100 can be used for a longer time, and convenience can be provided to the user.

[0137] In addition, the odor stimulation unit 64 may include a sensing unit (not shown) to sense the remaining amount of the aroma substance stored in each of the plurality of aroma storage units. Here, as an example, the sensing unit (not shown) may be at least one of a weight sensor, a distance sensor (or a laser measurement sensor), and an image sensor, but is not limited thereto, and all types of sensors that can measure the remaining amount of a substance may be applied. As an example, a plurality of sensing units (not shown) may be provided to correspond to each of the plurality of aroma storage units.

[0138] As a result of analyzing the signal sensed by the sensing unit (not shown), when the remaining amount of the first aroma substance stored in the first aroma storage unit among the plurality of aroma storage units is less than or equal to the preset remaining amount, the control unit 50 can provide a replacement reminder through at least one of the plurality of stimulation units 60 to remind the replacement of the first aroma storage unit including the first aroma substance below the preset remaining amount. At this time, the content of the first aroma storage, even if omitted below, can also be applied to the plurality of aroma storage units.

[0139] For example, it is assumed that the first aroma substance in liquid form is stored in the first aroma storage portion, a weight sensor is provided as a sensing portion (not shown) in the first aroma storage portion, and the remaining amount is preset to be 10 g.

[0140] In this case, as an example, when the weight value measured by the weighing sensor in the first fragrance storage section is 10g, the control unit 50 can determine that the remaining amount of the first fragrance substance is less than the preset remaining amount (i.e., 10g), and therefore, a replacement reminder for replacing the first fragrance storage section can be provided by at least one stimulation unit among the multiple stimulation units 60.

[0141] Exemplarily, when a replacement reminder is provided through the vibration stimulation unit 61, the control unit 50 may control the vibration stimulation unit 61 to turn on / off the vibration with the fifth stage of vibration intensity at a cycle of 1 second. As another example, when a replacement reminder is provided through the sound stimulation unit 62, the control unit 50 may control the action of the sound stimulation unit 62 to provide a voice guidance such as "the first fragrance substance needs to be replaced". In addition, when a replacement reminder is provided through the light stimulation unit 63, the control unit 50 may control the action of the light stimulation unit 63, as an example, to light up (on) a red light and keep it for 1 minute.

[0142] In this way, the control unit 50 confirms (checks) the remaining amount of the fragrance substance stored in the multiple fragrance storage units based on the analysis result of the sensing signal of the sensing unit (not shown), and when the remaining amount is below the preset remaining amount, a replacement reminder is provided through at least one of the multiple stimulation units 60, thereby allowing the user to use or manage the device 100 more easily and conveniently.

[0143] The present application proposes a real-time biofeedback device (the present device) 100 using an electrocardiogram.

[0144] The device 100 can use the user's electrocardiogram signal obtained (measured) by the electrocardiograph 10 to monitor the user's heart state in real time. In addition, the device 100 can provide feedback to the user based on the result of analyzing the obtained electrocardiogram signal using at least one stimulus of vibration, sound, light (color) and smell, whereby the user 3 can guide the change of the electrocardiogram signal to cause the user's action to change. As described above, the device 100 can be set in the form of a patch type, a watch type, etc.

[0145] The device 100 can obtain the user's electrocardiogram signal through the electrocardiograph 10, and grasp the user's heart state (normal state, suspected abnormal state, abnormal state, etc.) in real time by analyzing the obtained electrocardiogram signal (as an example, by analyzing using a medical algorithm), and record relevant information. That is, the device 100 can store (record) the results analyzed by the analysis unit 40 (i.e., the state diagnosis result) and even the information related to the action control forms of the multiple stimulation units 60 in a database (not shown).

[0146] In other words, the device 100 attaches the electrocardiograph 10 to the body of the user 3 in the form of lead electrodes or stickers (i.e., the electrocardiograph is connected to a part of the user's body), and the electrocardiograph 10 can measure the electrocardiogram signal of the user 3. The device 100 can grasp the user's heart state (normal, suspected abnormal, etc.) in real time or record it by analyzing the electrocardiogram signal measured (obtained) by the electrocardiograph 10.

[0147] The electrocardiogram measurement technology known in the art is only used as a basic medical examination to diagnose the health status of a user, and the technology for immediately feeding back the diagnosis result to the user is still in an immature state.

[0148] Therefore, the present device 100 can use the "real-time electrocardiogram signal" obtained by the electrocardiograph 10 as an analysis source to stabilize and wake up the state of the user 3. The present device 100 can obtain and collect the electrocardiogram signal of the user 3 measured by the electrocardiograph 10 from the electrocardiograph 10, and the electrocardiograph 10 can be implemented in various forms (for example, a patch type, a watch type, a handle, a piece of furniture, etc.). Based on the results of analyzing the electrocardiogram signal obtained from the electrocardiograph 10 (status diagnosis results, etc.), the present device 100 provides feedback to the user on the current state of the user through a plurality of stimulation units 60 (61, 62, 63, 64) built in the present device 100 that can provide various types of stimulation (stimulations such as vibration, sound, light, and smell).

[0149] Through such feedback (i.e., by feeding back the user's heart state or health state, etc. through vibration, sound, light, smell, etc.), the device 100 can stabilize or wake up the user. That is, through feedback, the device 100 can stabilize the user's state and provide the user with a wake-up (recognition) function for his or her current heart state or even health state.

[0150] That is, the device 100 can control the action of at least one of the multiple stimulation units 60 including the vibration stimulation unit 61, the sound stimulation unit 62, the light stimulation unit 63, and the odor stimulation unit 63 in order to control the user's state (heart state or even health state) based on the analysis result (state diagnosis result) of the electrocardiogram signal, and feed back at least one stimulation of vibration, sound, light, and odor to the user. Thus, the device 100 can stabilize the user and / or wake up the user.

[0151] When the device 100 is provided as including the electrocardiograph 10, as an example, the device 100 can be differently expressed as an electrocardiograph 10 integrated feedback device (electrocardiograph 10 integrated feedback device). Figure 1In addition, when the present device 100 and the electrocardiograph 10 are separately constituted, as an example, the present device 100 can be differently expressed as an electrocardiograph 10-separated feedback device (i.e., an electrocardiograph-separated biofeedback device).

[0152] This device 100, based on the analysis results of the electrocardiogram signal obtained by the electrocardiograph 10, feeds back at least one stimulus of vibration, sound, light and smell according to the user's heart state, so that the user can recognize his or her own heart state and even health state (normal state or abnormal state, stable state or unstable state, etc.).

[0153] For example, when vibration stimulation (biofeedback) is applied to the body of the user 3 according to the heart rate, blood pressure can be lowered. Thus, the device 100 provides feedback on at least one stimulation of vibration, sound, light and smell according to the heart rate (heart rate) determined by the analysis unit 40 (synchronous), thereby greatly improving the user's physical and mental stabilization and awakening effects.

[0154] In addition, as an example, the device 100 can analyze the user's state (changes in electrocardiogram signals) before and after using the meditation application in combination with the meditation application, and can control the actions of the plurality of stimulation units 60 based on the analysis results. As an example, when the device 100 is applied to the steering wheel of a car, the device 100 can provide tactile feedback to wake up the driver.

[0155] The device 100 can provide at least one of vibration, sound, light (light, color) and smell as various types of stimulation according to the user's state, so as to stabilize the user's body and mind and wake the user up.

[0156] The device 100 can be provided in a form that can be attached or worn on a part of the user's body, and can be formed to be small and light for easy carrying. As an example, when the device 100 is formed in a patch form, the device 100 can be differently expressed as a patch-type electrocardiogram terminal for biofeedback.

[0157] The present application provides a biofeedback device (the present device, 100) using an electrocardiogram, thereby being able to solve the problems of existing biofeedback technologies (i.e., space limitations, and a complex structure due to multiple wires connected to electrodes, which limits the movement / exercise of the user, etc.).

[0158] In addition, the present application can provide effects such as reducing the user's stress, stabilizing the body and mind, and lowering blood pressure by providing the present device 100. The present device 100 can apply various types of stimulation (vibration, sound, light, and odor-related stimulation) (biofeedback) to the user's body according to the heart rate (heart rate), thereby lowering blood pressure, etc.

[0159] In addition, as an example, when the user is meditating or doing yoga, the device 100 can synchronize the vibration stimulation unit 61 with the user's heart rate to apply vibration stimulation to the user. The device 100 can be applied to yoga products, massage chairs, car steering wheels, etc., but is not limited thereto.

[0160] In the above example, the sound stimulation provided by the sound stimulation unit 61 of the present device 100 is provided in the form of a voice guide (i.e., a voice message), but the present invention is not limited thereto. The sound stimulation may be provided in the form of music (music by genre, such as love songs, R&B, music, dance, etc.).

[0161] Fig.12a 1 is a diagram for explaining the biofeedback principle of the biofeedback device 100 using an electrocardiogram according to an embodiment of the present application.

[0162] refer to Fig.12a As an example, the device 100 may be provided in the form of a part attached to the body of the user 3. The signal acquisition unit 30 of the device 100 may acquire the electrocardiogram signal of the user 3 from the electrocardiograph 10 in the device 100.

[0163] The analyzing section 40 may diagnose the state of the user by analyzing the obtained electrocardiogram signal, and thereby may provide a diagnosis result of the state of the user.

[0164] Regarding the user's state, the analysis unit 40 can diagnose (analyze) whether the user's 3 heart state is a normal state or an abnormal state (for example, an arrhythmia state, a suspected arrhythmia state, etc.).

[0165] In order to determine whether the user 3 is in an arrhythmia state, the analysis unit 40 may apply an arrhythmia reading algorithm to the acquired electrocardiogram signal for analysis. Here, the arrhythmia reading algorithm may include an algorithm for determining whether an arrhythmia is present based on the RR interval, an algorithm for determining whether an arrhythmia is present based on the QRS duration value, and an algorithm for determining an arrhythmia algorithm by comparing the electrocardiogram morphology. However, the present invention is not limited thereto and may be applied to various arrhythmia reading algorithms that are currently known or will be developed in the future.

[0166] As an example, the analysis unit 40 may use a 2×1 multiplexer to provide, as a state diagnosis result, whether the user's heart state is normal or abnormal.

[0167] The control unit 50 may control the action of at least one of the plurality of stimulation units 60 using, for example, a 4×1 multiplexer based on the state diagnosis result provided from the analysis unit 40. The control unit 50 may control the action of the plurality of stimulation units 60 to provide the user 3 with biofeedback associated with at least one of a plurality of types of stimulation (e.g., vibration stimulation, sound stimulation, light stimulation, and odor stimulation).

[0168] In this case, when the control unit 50 controls the operation of at least one of the plurality of stimulation units 60 based on the state diagnosis result, the operation of at least one stimulation unit may be controlled by taking into account the user's stimulation receiving environment, as an example.

[0169] For example, it is assumed that based on the information selected by the user 3 (for example, the selected information that the sound stimulation cannot be received), the analysis unit 40 analyzes that the environment in which the user cannot receive the sound stimulation (that is, the environment in which the user is located is an environment in which no sound can be heard, such as in an airplane, etc.). In this case, the control unit 50 can control the operation of at least one of the stimulation units 60 other than the sound stimulation unit 61 (that is, the vibration stimulation unit, the light stimulation unit, and the odor stimulation unit) based on the information selected by the user 3.

[0170] The device 100 can provide the user 3 with a stable state or induce the user 3 to wake up by controlling the actions of the plurality of stimulation units 60 by the control unit 50 .

[0171] Figure 12b 1 is a diagram for explaining a case where vibration stimulation is fed back as biofeedback in the biofeedback device 100 using an electrocardiogram according to an embodiment of the present application.

[0172] refer to Figure 12b , the device 100 can apply an arrhythmia reading algorithm to the acquired electrocardiogram signal to analyze the electrocardiogram signal of the user 3 obtained from the electrocardiograph 10. Thus, the control unit 50 of the device 100 can control the action of the vibration stimulation unit 61 as an example among the multiple stimulation units 60 based on the state diagnosis result of the user 3. Thus, the control unit 50 can provide the user with biofeedback related to vibration (vibration stimulation) by controlling the vibration stimulation unit 61.

[0173] At this time, as an example, when the state diagnosis result analyzes that the user's heart state is normal, the control unit 50 can control the vibration stimulation unit 61 to prevent the vibration stimulation unit 61 from vibrating (i.e., non-vibration operation). By controlling the vibration stimulation unit 61 to be non-vibrating by the control unit 50, the state of the user 3 can be kept in a stable state.

[0174] On the other hand, when the user's heart state is abnormal (arrhythmia state or suspected arrhythmia state) as a result of the state diagnosis, the control unit 50 can control the vibration stimulation unit 61 so that the vibration stimulation unit 61 provides vibration with the strongest vibration intensity of the fifth stage among the vibration intensities divided into five stages. The control unit 50 controls the vibration stimulation unit 61 to provide vibration stimulation with, for example, the fifth stage of vibration intensity, thereby providing (inducing) the user 3 to wake up (recognize) that his or her heart state is an abnormal state (especially, an arrhythmia state or a suspected arrhythmia state).

[0175] Fig.12c 1 is a diagram for explaining a case where sound stimulation is fed back as biofeedback in the biofeedback apparatus 100 using an electrocardiogram according to an embodiment of the present application.

[0176] refer to Fig.12c , the device 100 can apply an arrhythmia reading algorithm to the acquired electrocardiogram signal. Thus, the control unit 50 of the device 100 can control the action of the sound stimulation unit 62 as an example among the multiple stimulation units 60 based on the state diagnosis result of the user 3. Thus, the control unit 50 can provide the user with biofeedback related to sound (sound stimulation) by controlling the sound stimulation unit 62.

[0177] At this time, as an example, when the state diagnosis result analyzes that the user's heart state is normal, the control unit 50 can control the sound stimulation unit 62 to prevent the sound stimulation unit 62 from emitting sound (i.e., silent operation). By controlling the sound stimulation unit 62 to be silent by the control unit 50, the state of the user 3 can be kept in a stable state.

[0178] On the other hand, when the user's heart state is abnormal (arrhythmia state or suspected arrhythmia state) as a result of the state diagnosis, the control unit 50 can control the sound stimulation unit 62 so that the sound stimulation unit 62 provides the highest sound among the sound intensities divided into five stages (or provides a siren sound). The control unit 50 controls the sound stimulation unit 62 to provide, for example, a sound stimulation related to a siren sound, thereby providing (inducing) the user 3 to wake up (recognize) that his or her heart state is abnormal (especially, arrhythmia state or suspected arrhythmia state).

[0179] Fig.12d 1 is a diagram for explaining a case where light stimulation is fed back as biofeedback in the biofeedback device 100 using an electrocardiogram according to an embodiment of the present application.

[0180] refer to Fig.12d, the device 100 can apply an arrhythmia reading algorithm to the acquired electrocardiogram signal. Thus, the control unit 50 of the device 100 can control the action of the light stimulation unit 63 as an example among the multiple stimulation units 60 based on the state diagnosis result of the user 3. Thus, the control unit 50 can provide the user with biofeedback related to light (light stimulation) by controlling the light stimulation unit 63.

[0181] At this time, as an example, when the state diagnosis result analyzes that the user's heart state is normal, the control unit 50 can control the light stimulation unit 63 to emit, for example, green light. The control unit 50 controls the light stimulation unit 63 to emit green light, so that the state of the user 3 can be kept in a stable state.

[0182] On the other hand, as a result of the state diagnosis, when the user's heart state is abnormal (arrhythmia state or suspected arrhythmia state), the control unit 50 can control the light stimulation unit 63 so that the light stimulation unit 63 emits, for example, red light. The control unit 50 controls the light stimulation unit 63 to emit red light, thereby providing (inducing) the user 3 to wake up (recognize) that his or her heart state is abnormal (especially, arrhythmia state or suspected arrhythmia state).

[0183] Fig.12e 1 is a diagram for explaining a case where odor stimulation is fed back as biofeedback in the biofeedback apparatus 100 using an electrocardiogram according to an embodiment of the present application.

[0184] refer to Fig.12e , the device 100 can apply an arrhythmia reading algorithm to the acquired electrocardiogram signal. Thus, the control unit 50 of the device 100 can control the action of the odor stimulation unit 64 as an example among the multiple stimulation units 60 based on the state diagnosis result of the user 3. Thus, the control unit 50 can provide the user with biofeedback related to odor (odor stimulation) by controlling the odor stimulation unit 62.

[0185] At this time, as an example, when the state diagnosis result analyzes that the user's heart state is normal, the control unit 50 can control the odor stimulation unit 64 to prevent the odor stimulation unit 64 from emitting an odor (i.e., no odor). By controlling the odor stimulation unit 64 to be odorless by the control unit 50, the state of the user 3 can be kept in a stable state.

[0186] On the other hand, as a result of the state diagnosis, when the user's heart state is abnormal (arrhythmia state or suspected arrhythmia state), the control unit 50 can control the odor stimulation unit 64 so that the odor stimulation unit 64 emits an odor. At this time, the control unit 50 can control the odor stimulation unit 64 to spit out an aroma (smell) corresponding to any one of the multiple types of aroma substances. The control unit 50 controls the odor stimulation unit 64 to emit an odor (spit out an odor), thereby providing (inducing) the user 3 to wake up (recognize) that his or her heart state is abnormal (especially, arrhythmia state or suspected arrhythmia state).

[0187] Next, a technology is described in which a motion sensor built into a wearable or adhesive electrocardiograph 10 without wires included in the present device 100 is used to sense the pasting direction (position, angle, etc.) of the electrocardiograph 10, and the sensed information is transmitted to a user terminal 20 (as a mobile terminal, such as a smartphone, tablet computer, PC, etc.) via wireless (Bluetooth, Wi-Fi, etc.), thereby guiding the electrocardiograph 10 to be pasted in the direction of the electrocardiogram lead intended by the user 3 (i.e., electrocardiogram lead guidance technology).

[0188] When explaining the electrocardiogram lead guidance technology, the descriptions of the above-mentioned system 1000, the device 100, the electrocardiograph 10, the user terminal 20, etc., even if omitted below, can also be applied to the electrocardiogram lead guidance technology.

[0189] In addition, in the following description, when explaining the electrocardiogram lead guidance technology, the electrocardiograph 10 is illustrated as an electrocardiograph that is integrated with the present device 100 (i.e., the electrocardiograph included in the present device). However, this is not limited to this. As described above, as another example, the electrocardiograph 10 can also be provided as a separate structure separated from the present device 100.

[0190] Regarding ECG lead guidance technology, refer again Figure 2 , the electrocardiograph 10 included in the present device 100 can be attached to a part of the body of the user 3. In other words, the present device 100 including the electrocardiograph 10 can be attached to a part of the body of the user 3. In the following description, the user 3 may be referred to as a patient.

[0191] The electrocardiograph 10 can utilize a plurality of sensors to obtain posture information and electrocardiogram signals. As an example, the electrocardiograph 10 can be a terminal, a patch type, or a wearable product. In addition, the posture information can include the position and angle information of the electrocardiograph 10. The electrocardiograph 10 can be pasted in the direction of a specific electrocardiogram lead to obtain an electrocardiogram signal. In addition, the electrocardiograph 10 can include a sensing unit 11 for obtaining posture information, and an electrode (sensor) for obtaining an electrocardiogram signal. As an example, the posture information can include information related to the current position and direction of the electrocardiograph 10.

[0192] In order to accurately grasp the user's heart state, the electrocardiograph 10 needs to be attached to a part of the user's 3 body (e.g., near the heart) in a predetermined direction (i.e., the direction of the standard posture information described later). That is, the electrocardiograph 10 needs to be attached to the electrode position and direction specified in advance to obtain an accurate electrocardiogram waveform.

[0193] According to the electrocardiograph 10, the electrocardiograph in the range of several mV measured around the heart is filtered by an LPF (Low Pass Filter) and applied as an input of an IA (Instrumentation Amplifier) ​​through a buffer. The electrocardiograph waveform is output after being amplified 1000 times at the IA end, and an electrocardiograph signal in the range of 1Hz to 35Hz is output through a BPF (Band Pass Filter) composed of a combination of an LPF and an HPF (High Pass Filter) connected to the output of the IA end. In addition, the electrocardiograph 10 can drive hardware capable of measuring electrocardiograph signals, filter analog electrocardiograph signals, and convert them into digital electrocardiograph signals before transmitting them to the user terminal 20. In addition, the electrocardiograph 10 can transmit only the electrocardiograph signal converted into a digital signal by an analog-to-digital converter to the user terminal 20. Exemplarily, the analog-to-digital converter can have a 24-bit resolution and a 250Hz sampling frequency. However, the structure of the electrocardiograph 10 is not limited thereto.

[0194] The user terminal 20 may provide guidance information for guiding the attaching direction of the electrocardiograph 10 based on the posture information obtained from the electrocardiograph 10. The guidance information may be information for providing the attaching direction of the electrocardiograph 10 to be attached in order to obtain a conventional standardized electrocardiogram signal.

[0195] In other words, for the electrocardiograph 10 provided integrally with the present device 100 or provided as a structure separate from the present device 100, the user terminal 20 can provide guidance information (feedback information) to guide the electrocardiograph 10 affixed to a part of the body of the user 3 to be affixed more accurately in the direction of the electrocardiogram lead intended by the user.

[0196] The sticking direction of the electrocardiograph 10 can be adjusted by the guide information provided by the user terminal 20 .

[0197] In this case, when the present device 100 is a biofeedback device integrated with the electrocardiograph 10, as an example, the user can adjust the pasting direction of the present device 100 itself including the electrocardiograph 10. As another example, when the present device 100 is a feedback device integrated with the electrocardiograph 10, the control unit 50 of the present device 100 can automatically adjust the pasting direction of the electrocardiograph 10 built into the present device 100 based on the guidance information provided from the user terminal 20. As another example, when the present device 100 is a biofeedback device separated from the electrocardiograph 10, the user can adjust the pasting direction of the electrocardiograph 10 by directly moving the electrocardiograph 10.

[0198] For example, the user terminal 20 can receive user input information for measuring the electrocardiogram in the direction of lead I. The user terminal 20 can provide guidance information so that the electrocardiograph 10 is located on the left chest (on the nipple) of the user 3. In addition, in order to measure the electrocardiogram in the direction of lead I, the user terminal 20 can provide guidance information so that the "+" electrode provided on the electrocardiograph 10 is close to the left arm LA of the user 3, and the "-" electrode is close to the right arm RA of the user 3. In addition, the electrocardiograph 10 can infer the angle difference between the first direction including the preset standard information of lead I and the direction information obtained based on the sensor. The user terminal 20 can provide different output characteristics of the guidance information based on the angle difference information inferred by the electrocardiograph 10.

[0199] For example, in medicine and academia, the measurement directions of the electrocardiogram leads (Lead I, II, III, aVL, aVR, aVF, V1, V2, V3, V4, V5, V6) have been standardized. The standard 12-lead electrocardiogram is divided into a bipolar lead that records the potential difference between two parts and a unipolar lead that records the potential of the part where the electrode is attached. The bipolar standard leads can be divided into Lead I, II, and III. Lead I is the voltage flowing between the left arm LA electrode and the right arm RA electrode (I=LA-RA). Lead II is the voltage flowing between the left leg LL electrode and the right arm RA electrode (II=LL-RA). Lead III is the voltage flowing between the left leg LL electrode and the left arm LA electrode.

[0200] In addition, the unipolar limb leads are divided into aVL, aVR, and aVF, and the electrodes are connected to the right hand, left hand, and left foot to record the electrocardiogram. At this time, since the size of the electrocardiogram waveform recorded by the unipolar limb leads is small, aVR, aVL, and aVF that amplify the electrocardiogram waveform by 1.5 times can be used. Among them, a can refer to the first letter of augmented.

[0201] The chest leads are divided into V1, V2, V3, V4, V5, and V6, and have the disadvantage that the standard leads or limb leads record the electrocardiogram at a position far away from the heart, but the chest leads record the electrocardiogram at a position closer to the heart. Among the positions of each chest lead, V1 can be located just beside the right sternum in the fourth intercostal space (between the 4th and 5th ribs). V2 can be located just beside the left sternum in the fourth intercostal space (between the 4th and 5th ribs). V3 can be located in the middle of V2 and V4. V4 can be located in the fifth intercostal space (between the 5th and 6th ribs) on the mid-clavicular line. V5 can be located on the left side of the anterior axilla to be horizontally parallel to V4. V6 can be located on the middle axillary line to be horizontally parallel to V4 and V5.

[0202] As an example, the user terminal 20 may output an electrocardiogram lead guide menu, an electrocardiogram measurement menu, an electrocardiograph pasting guide menu, etc. For example, an application program that provides an electrocardiogram lead guide menu and an electrocardiogram measurement menu may be installed on the user terminal 20, and the electrocardiogram lead guide menu, the electrocardiogram measurement menu, and the electrocardiograph pasting guide menu may be provided through the installed application program.

[0203] Figure 6 is a block diagram of an electrocardiograph 10 included in a biofeedback apparatus 100 using an electrocardiogram according to an embodiment of the present application.

[0204] The electrocardiograph 10 included in the present device 100 is an electrocardiograph 10 according to an embodiment of the present invention, and is hereinafter referred to as the present electrocardiograph 10 for convenience of description.

[0205] refer to Figure 6 The electrocardiograph 10 may include a sensor unit 11, a generator unit 12, a sensing unit 13, and a communication unit 14. However, the structure of the electrocardiograph 10 is not limited thereto. For example, the electrocardiograph 10 may include a power supply unit (not shown) for applying power.

[0206] The sensing unit 11 can use multiple sensors to obtain position and angle information. In other words, the sensing unit 11 can use an acceleration sensor and a gyro sensor to obtain the position and angle information of the electrocardiograph 10. As an example, the multiple sensors can be acceleration sensors and gyro sensors. The sensing unit 11 can use an acceleration sensor and a gyro sensor to obtain the position and angle information of the electrocardiograph 10. In addition, the sensing unit 11 can use multiple sensors to obtain the current position and angle information of the electrocardiograph 10 including information such as X-coordinates, Y-coordinates, and Z-coordinates. In addition, the sensing unit 11 can obtain the current position and angle information including information such as roll, pitch, and yaw angles.

[0207] For example, an acceleration sensor is a sensor for measuring the dynamic force of an object such as acceleration vibration and impact, and refers to a sensor that can sense the motion state of an object. A gyroscope sensor is different from an acceleration sensor that measures acceleration, and measures angular velocity. As another example, the multiple sensors of the sensing unit 11 may include an accelerometer, an angular velocity meter, a geomagnetic field meter, a GPS, a computer vision, etc.

[0208] In addition, the sensing unit 11 may include electrodes (sensors). The sensing unit 11 may obtain an electrocardiogram signal of the user 3 from the electrodes (sensors). The sensing unit 11 may obtain an electrocardiogram signal. An electrocardiogram signal is referred to as an electrocardiogram or an electrocardiogram signal, and refers to an analysis of the electrical activity of the heart and recording it in the form of a wavelength. More specifically, it is a wavelength composed of the vector sum of action potentials generated by the special excitatory & conductive system of the heart. That is, it is a signal of the vector sum signal of action potentials generated in the sinoatrial node (SAnode), atrioventricular node (AV node), His bundle, His bundle branch, Purkinje fibers, etc., which are various components of the heart, measured from electrodes in contact with the outside of the body. When measuring an electrocardiogram, two or more electrodes are used, and the electrodes form a pair.

[0209] Even if the electrocardiogram signal, electrocardiogram or electrocardiogram signal are used in combination, they do not represent different meanings respectively but represent the same electrocardiogram signal.

[0210] The generating unit 12 can predict the current posture information of the electrocardiograph based on the position and angle information of the electrocardiograph obtained from the sensing unit 11. For example, the generating unit 12 can calculate the current position and current posture of the electrocardiograph 10. The generating unit 12 can predict the current position of the electrocardiograph 10 including information such as the X-coordinate, the Y-coordinate, and the Z-coordinate, and can also predict the current posture of the electrocardiograph 10 including information such as the roll, pitch, and yaw angle. Roll refers to rotation about the front-rear axis, pitch refers to the up-and-down movement of the electrocardiograph 10, and the yaw angle refers to the angle of inclination to one side. The generating unit 12 can calculate the current position and current posture (angle) of the electrocardiograph 10 to generate direction information.

[0211] In addition, the generating unit 12 can calculate the angle difference between the standard posture information and the current posture information, and infer the difference between the standard posture information and the current posture information. The standard posture information can be set to correspond to multiple standard direction information respectively. In addition, the generating unit 12 can infer the angle difference between the preset first standard posture information and the current posture information. In addition, the generating unit 12 can infer the angle difference between the preset second standard posture information and the current posture information. In addition, the generating unit 12 can infer the angle difference between the preset third standard posture information and the current posture information. Among them, the first standard posture information can be information related to lead I. In addition, the second standard posture information can be information related to lead II. In addition, the third standard posture information can be information related to lead III.

[0212] Figure 7 1 is a schematic diagram showing the pasting direction of the electrocardiograph included in the biofeedback device 100 using an electrocardiogram according to an embodiment of the present application. Figure 7 2 is a diagram showing an example of the direction in which the electrocardiograph 10 is attached in order to provide electrocardiogram lead guidance technology with respect to the electrocardiograph included in the present device 100 .

[0213] For standard posture information, as an example reference Figure 7 (a), lead I is used to record the potential difference between the left hand electrode (+) and the right hand electrode (-), and needs to be set to be horizontal with the "-" electrode and the "+" electrode of the electrocardiograph 10. In other words, the standard posture information of lead I can be the case where the "-" electrode and the "+" electrode are in a horizontal state.

[0214] In addition, refer to Figure 7 (b), lead II is used to record the potential difference between the left foot electrode (+) and the right hand electrode (-), and can obtain an electrocardiogram signal in a state where the "+" electrode of the electrocardiograph 10 is tilted at a specific angle (for example, -44°) based on the "+" electrode. In other words, the standard posture information of lead II can be a state where the "-" electrode and the "+" electrode are tilted at a specific angle. As an example, in order to measure the electrocardiogram in the direction of lead II, the electrocardiograph 10 can be set to a state where the "-" electrode is tilted toward the right hand and the "+" electrode is tilted toward the left foot.

[0215] In addition, refer to Figure 7(c), lead III is used to record the potential difference between the left foot electrode (+) and the left foot electrode (-), and can obtain an electrocardiogram signal in a state where the "+" electrode of the electrocardiograph 10 is tilted at a specific angle (for example, -134°) based on the "+" electrode of the electrocardiograph 10. In other words, the standard posture information of lead III can be a state where the "-" electrode and the "+" electrode are tilted at a specific angle. As an example, in order to measure the electrocardiogram in the direction of lead III, the electrocardiograph 10 can be set to a state where the "-" electrode is tilted toward the left hand and the "+" electrode is tilted toward the left foot.

[0216] In addition, the generating unit 12 may estimate the angle difference between the preset standard posture information and the current posture information. Figure 7 , you can Figure 7 The blue line shown in (a) and (b) is called the standard posture information of lead I, and the red line is called the current posture information.

[0217] When the standard posture information of lead 1 is consistent with the current posture information, the generating unit 12 may generate the angle information in the current posture information of the electrocardiograph 10 as 0°. Figure 7 As shown in (a), when the difference between the standard posture information and the current posture information of lead 1 is 23°, the generating unit 12 generates the angle information in the current posture information of the electrocardiograph 10 as 23°. Figure 7 As shown in (a), when the difference between the standard posture information and the current posture information of lead I is -8°, the angle information in the current posture information of the electrocardiograph 10 is generated as -8°.

[0218] The sensing unit 13 can sense whether the electrode (sensor) is attached to a part of the body of the user 3. As an example, the sensing unit 13 can sense whether the electrode (sensor) is attached to a part of the body of the user 3 (for example, the left chest nipple). The sensing unit 13 can sense whether the electrode (sensor) is attached based on temperature, electrocardiogram acquisition signals, etc., but is not limited thereto.

[0219] The communication unit 14 can transmit the current posture information and the electrocardiogram lead signal to the user terminal 20. In addition, the communication unit 14 can transmit the angle difference between the preset standard posture information and the current posture information to the user terminal 20. As an example, the communication unit 15 can transmit the information and signal obtained from the electrocardiograph 10 to the user terminal 20 through the network. The communication unit 14 can transmit the direction information and the electrocardiogram lead signal to the user terminal 20 through a network such as Bluetooth, Wi-Fi, etc.

[0220] In addition, the communication unit 14 may provide (transmit) the angle difference information of the preset standard posture information and the current posture information estimated by the generation unit 12 and the electrocardiogram signal to the user terminal 20 when the sensing unit 13 senses whether the paste is on. When the sensing unit 13 senses whether the paste is on, the electrocardiogram signal can be obtained from the electrode (sensor), so the communication unit 14 may provide (transmit) the angle difference information estimated by the generation unit 12 and the electrocardiogram signal obtained from the sensing unit 11 to the user terminal 20 when the sensing unit 13 senses whether the paste is on.

[0221] On the contrary, when the sensing unit 13 senses that the sticking is disconnected (Off), the communication unit 14 may provide (transmit) the angle difference information between the preset standard posture information estimated by the generation unit 12 and the current posture information to the user terminal 20 .

[0222] Figure 8 1 is a block diagram showing a structure of a user terminal 20 included in a biofeedback system 1000 using an electrocardiogram according to an embodiment of the present invention. In particular, Figure 8 This is a diagram for explaining the functions of the user terminal 20 required for providing the electrocardiogram lead guidance technology.

[0223] refer to Figure 8 In order to provide the electrocardiogram lead guidance technology, the user terminal 20 may include a user input receiving unit 21 and a guidance information providing unit 22. However, the structure of the user terminal 20 is not limited thereto. For example, the user terminal 20 may include a data storage unit (not shown) for storing information received from the electrocardiograph 10.

[0224] The user input receiving unit 21 may receive user input information of selecting at least one of a plurality of standard direction information items. For example, the plurality of standard direction information items may include a lead I direction information item, a lead II direction information item, and a lead III direction information item.

[0225] The user can select any one of the electrocardiogram lead direction items that he wants to obtain from the multiple standard direction information items. For example, the user input receiving unit 21 can receive user input information corresponding to the lead I direction information item. The guidance information providing unit 22 can correspond to the lead I direction information item as the user input information, and provide guidance information related to the position and direction information where the electrocardiograph 10 needs to be pasted in order to obtain the lead I direction electrocardiogram measurement signal.

[0226] The guidance information providing unit 22 can provide guidance information based on the user input information and the angle difference information obtained from the electrocardiograph. In other words, the guidance information providing unit 22 can provide guidance information for the pasting direction of the electrocardiograph 10 based on the user input information and the angle difference information between the preset standard posture information and the current posture information obtained from the electrocardiograph 10.

[0227] For example, the guidance information providing unit 22 may correspond to the lead I direction information item as user input information, and provide guidance information related to the position and direction information on which the electrocardiograph 10 needs to be pasted in order to obtain the lead I direction electrocardiogram measurement signal.

[0228] In addition, the guidance information providing unit 22 may provide guidance information based on the angle difference information provided by the electrocardiograph 10 so as to make the current posture information consistent with the preset standard posture information.

[0229] Fig. 9 FIG. 1 is a diagram showing an example of outputting guidance information by the guidance information providing unit of the user terminal 20 included in the biofeedback system 1000 using an electrocardiogram according to an embodiment of the present application.

[0230] refer to Fig. 9 , the guidance information providing unit 22 can change the output characteristics of the guidance information based on the user input information and the angle difference information. As an example, the output characteristics may include at least one of flashing speed, vibration, and sound. In other words, the output characteristics of the guidance information can be changed based on the pasting direction of the electrocardiograph 10 associated with the standard posture information corresponding to the user input information and the angle difference information between the preset standard posture information provided by the electrocardiograph 10 and the current posture information.

[0231] The guidance information providing unit 22 can set the flashing speed to be different based on the angle difference corresponding to each standard information of the preset angle. As an example, the guidance information providing unit 22 can change the output characteristics to flash in a 2-second cycle when the angle difference information is above ±60°. In addition, when it is above ±30° to below ±60°, the output characteristics can be changed to flash in a 1.5-second cycle. In addition, when it is above ±10° to below ±30°, the output characteristics can be changed to flash in a 1.0-second cycle. In addition, when it is above ±5° to below ±10°, the output characteristics can be changed to flash in a 0.5-second cycle. In addition, when it is below ±5°, the output characteristics can be changed to stop red flashing and display blue.

[0232] As an example, refer to Fig. 9(a), when the user input receiving unit 21 receives the user input information corresponding to the lead I direction information item, the guidance information providing unit 22 causes the first arrow 2 to output red. In addition, the guidance information providing unit 22 can change the output characteristics of the first arrow 2 based on the angle difference information, that is, the angle difference information of the preset first standard posture information and the current posture information.

[0233] The guide information providing unit 22 can obtain the angle difference information of 23° from the electrocardiograph 10, and change the output feature of the first arrow 2 based on the output feature corresponding to the preset angle difference information. Fig. 9 In (a), the angle difference information is 23°, so the guidance information providing unit 22 changes the output feature so that the first arrow 2 flashes at a period of 1.0 second.

[0234] In addition, refer to Fig. 9 (b), when the user input receiving unit 21 receives the user input information corresponding to the lead I direction information item, the guidance information providing unit 22 causes the second arrow 2' to be output in red. In addition, the guidance information providing unit 22 can change the output characteristics of the second arrow 2' based on the angle difference information, that is, the angle difference information of the preset second standard posture information and the current posture information.

[0235] The guide information providing unit 22 can obtain the angle difference information of -8° from the electrocardiograph 10, and change the output characteristics of the second arrow 2' based on the output characteristics corresponding to the preset angle difference information. Fig. 9 In (b), the angle difference information is -8°, so the guidance information providing unit 22 may change the output feature to make the second arrow 2' flash at a period of 0.5 seconds.

[0236] Fig.10 1 is a diagram for explaining an electrocardiogram lead guidance technique using an electrocardiograph 10 and a user terminal 20 included in a biofeedback system 1000 using an electrocardiogram according to an embodiment of the present invention.

[0237] refer to Fig.10 According to an embodiment of the present application, in order to obtain electrocardiogram lead guidance technology, the user can prepare the electrocardiograph 10 and the user terminal 20 provided by the present invention.

[0238] Electrodes (sensors) can be attached and set on the electrocardiograph 10, and the user can start the power supply of the electrocardiograph 10. In addition, the user can run the electrocardiogram lead guidance application downloaded on the user terminal 20, thereby providing the electrocardiogram lead guidance technology.

[0239] The user can select at least one of the leads I, II, and III measured by the electrocardiogram lead guidance application downloaded to the user terminal 20. The user terminal 20 can set any of the arrows of the selected lead in the triangle to output differently based on the user input information.

[0240] As an example, the user positions the electrode adhesive surface of the electrocardiograph 10 toward the body surface and places it on the left chest (nipple) without being attached to the body surface. The electrocardiograph 10 can predict the current posture information using the sensor unit 11. In addition, the electrocardiograph 10 can estimate the angle difference between the preset standard posture information and the current posture information, and transmit the estimated angle difference information to the user terminal 20.

[0241] The user terminal 20 can use the angle and arrow to display the difference between the direction of the electrocardiograph 10 and the user's input information (selected lead information) on the screen of the user terminal 20. In addition, the user terminal 20 can output different arrow flashing speeds on the screen based on the estimated angle difference information.

[0242] The user can adjust the position of the electrocardiograph 10 so that the angle difference information displayed on the user terminal 20 is within 5°, and when the angle difference information displayed on the user terminal 20 becomes within 5° and the flashing of the arrow text stops, the electrocardiograph 10 is pasted on a part of the body of the user 3.

[0243] The user terminal 20 may output an electrocardiogram signal and heart rate information obtained from the electrocardiograph 10 when the electrocardiograph 10 is attached to a part of the body of the user 3 .

[0244] Generally, an electrocardiograph is a device that uses the potential difference between two points on the body surface to detect the electromotive force generated by the heart muscle activity, amplifies it, and displays it on a recording paper as a waveform. It is generally used to diagnose heart diseases by analyzing and recording the minute waveform of the potential difference generated between the heart and the arms and legs as the extremities of the body. Electrocardiographs include electrocardiographs used in hospitals or medical institutions, portable electrocardiographs that can also be used at home or in daily life, and wearable electrocardiographs. Recently, electrocardiographs that can be connected to smartphones for measurement have also been developed.

[0245] In medicine and academia, the measurement directions of ECG leads (Lead I, II, III, aVL, aVR, aVF, V1, V2, V3, V4, V5, V6) have been standardized. Wearable or adhesive electrocardiographs with freedom and no additional wires measure ECG leads differently depending on the direction in which the electrocardiograph is attached. When attaching a wearable or adhesive electrocardiograph, if the standard lead direction is not accurately matched, it is difficult to obtain the intended ECG lead signal. Current products are fixed to a specific direction to measure the ECG.

[0246] On the one hand, there is a situation where the ECG leads need to be applied differently depending on the patient's symptoms and characteristics. At this time, when non-medical personnel who are not skilled medical personnel wear them by themselves, the pasting direction may be incorrect, thereby failing to obtain accurate ECG signals.

[0247] Therefore, according to the ECG lead technology proposed in this application, the system 1000 uses the (motion) sensor built into the electrocardiograph to sense the pasting direction (position, angle, etc.) of the electrocardiograph, and transmits it to the mobile terminal (smartphone, tablet computer, PC) via wireless (Bluetooth, Wi-Fi, etc.), so as to guide the electrocardiograph to be pasted in the direction of the ECG lead intended by the user.

[0248] That is, based on the electrocardiograph 10 in the present system 1000 and the electrocardiograph lead guidance technology provided by the user terminal 20, the present application utilizes a (motion) sensor built into the electrocardiograph to sense the pasting direction (position, angle, etc.) of the electrocardiograph, and transmits it to a mobile terminal (smartphone, tablet computer, PC) via wireless (Bluetooth, Wi-Fi, etc.), thereby guiding the electrocardiograph to be pasted in the direction of the electrocardiograph lead intended by the user. Therefore, non-medical personnel who are not skilled medical personnel can also paste the electrocardiograph in the correct direction.

[0249] Below, based on the above detailed description, the workflow of this application is briefly described.

[0250] Fig.11 It is a flowchart of a control method of a biofeedback device using an electrocardiogram according to an embodiment of the present application.

[0251] Fig.11 The control method of the biofeedback device using an electrocardiogram shown in the above can be executed by the above-mentioned present device 100. Therefore, even if the content is omitted below, the content described in the present device 100 can also be applied to the description of the control method of the biofeedback device using an electrocardiogram.
