Description

[Technical field]

[0001] The present invention relates to a biosignal measuring patch device for measuring a biosignal such as an electrocardiogram signal and utilizing it for health management, and a method of using the same. [Background technology]

[0002] As the economic level improves and the population ages, the general public becomes more interested in health management, and there is an increasing interest in health management that manages health conditions through physical activity and regular sports activities. In order to carry out such health management, it is necessary to develop a biosignal measuring device equipped with a sensor that can constantly measure biosignals such as an electrocardiogram (ECG), respiration, heart pulse wave, and an electromyogram (EMG) related to muscle movement.

[0003] As an example, an electrocardiogram (ECG), one of the most common types of biometric information, is a record of the electrical current generated when the cardiac muscle contracts and expands due to the heart beating. Electrodes are attached to the skin of the body to measure the electrical current or voltage caused by the contraction of the cardiac muscle, and the measured data is then plotted on a graph.

[0004] Such electrocardiograms are used to check for the presence or absence of cardiac abnormalities, and are used as a basic measuring method for diagnosing cardiac diseases such as angina pectoris, myocardial infarction, and arrhythmia.

[0005] As described above, in order to measure an electrocardiogram, the electrocardiogram (ECG) sensor electrodes must maintain intimate contact with the skin, as must the electromyogram (EMG) sensor electrodes for measuring an electromyogram and the sensor for measuring a respiratory signal. However, there are problems in that the quality of the measured signal is reduced due to the problems of the adhesive strength decreasing over time, the curved shape of the human body, and the limitations of the adhesive that can be applied to the human body. Therefore, there is a demand for a new bio-measuring device that can bring the sensor into close contact with the skin and maintain the contact strength.

[0006] An example of Patent Document 1 is shown in FIG. 1. Referring to this, a housing 20 including a battery and an electrode 30 are fixed on a substrate 10 and connected by a conductor. In this case, the substrate 10 can be formed to be flexible, but the housing 30 is not easily attached to the human body due to its rigidity. Furthermore, there is a problem that the housing 30 is not well adhered and sags in the direction of gravity due to the weight of the housing ejection and the battery, thereby reducing the adhesiveness of the remaining substrate.

[0007] In order to solve such a problem, Patent Document 1 discloses a structure in which an adhesive part 12 is formed only on the part of the substrate 10 where the electrode 30 is formed, and no adhesive part is formed on the housing 20 or the part 11 between the housing 20 and the electrode 30, and the adhesive area is separated. However, in this case, the substrate 10 is attached to the user's body in a dangling manner, and there is a limit to preventing the substrate 10 from falling off the body due to the weight of the housing 20.

[0008] The above-mentioned background art is technical information that the inventor possessed for the purpose of deriving the present invention or that he acquired in the process of deriving the present invention, and is not necessarily publicly known art that was disclosed to the general public prior to the filing of the present application. [Prior art documents] [Patent documents]

[0009] [Patent Document 1] U.S. Patent Publication US11337632B2 Summary of the Invention [Problem to be solved by the invention]

[0010] The present invention is intended to solve the problems of the prior art as described above, and specifically aims to provide a means for improving the adhesion quality by adhering a sensor for measuring vital signs to the skin and maintaining contact force, as well as a vital sign measurement patch device and a method for using the same.

[0011] However, such problems are merely examples, and the problems to be solved by the present invention are not limited to these. [Means for solving the problem]

[0012] In order to solve the above-mentioned problems, an embodiment of the present invention provides a biosignal measuring patch device as follows.

[0013] A biosignal measurement patch device according to one embodiment of the present invention includes a substrate made of a flexible material, a housing arranged in a first region of the substrate, and a biosignal measurement sensing electrode arranged in a second region of the substrate, and a slit is formed in the substrate in a direction dividing the first region and the second region.

[0014] Also, a plurality of the slits may be formed in series, and a bridge may be formed between the plurality of slits to connect the first region and the second region.

[0015] The device may further include a reference electrode disposed on the substrate or the housing, and a skin-attached sensing electrode disposed on the substrate for measuring the attachment quality of the biosignal measuring sensing electrode based on a change in capacitance with the reference electrode.

[0016] In addition, a plurality of the skin-attached sensing electrodes may be disposed at positions surrounding the sensing electrode for measuring the biological signal.

[0017] Alternatively, the reference electrode may be disposed in the first region or the housing, and the skin-attached sensing electrode may be disposed in the second region.

[0018] Also, a plurality of the sensing electrodes for measuring the biological signal may be provided, and a plurality of the skin-attached sensing electrodes may be provided and alternately arranged between the plurality of the sensing electrodes for measuring the biological signal.

[0019] The skin-attached sensing electrode is further disposed in the first region, and a distance between the skin-attached sensing electrode in the first region and the slit is closer than a distance between the skin-attached sensing electrode and a center of the housing.

[0020] The biosignal measuring sensing electrodes may further include at least one of a respiration sensor, an electrocardiogram (ECG) sensor, a snoring sensor, a turning sensor, an electromyogram sensor, a temperature sensor, and an impedance sensor.

[0021] Also, the first region may be disposed in a lower region of the substrate, and the second region may be disposed in an upper region of the substrate.

[0022] In addition, a method of using a biosignal measuring patch device according to one embodiment of the present invention is a method of using the above-mentioned biosignal measuring patch device, and includes a substrate positioning step of positioning one side of a substrate on which the housing and the biosignal measuring electrodes are arranged, at a user's heart area, and an attachment step of attaching the substrate to the user's skin using an adhesive patch attached to the other side of the substrate, and in the substrate positioning step, the substrate can be positioned so that the first region is located lower than the second region.

[0023] Other aspects, features, and advantages in addition to those described above will become apparent from the following detailed description of the invention, the claims, and the drawings. Effect of the Invention

[0024] According to the above-mentioned means for solving the problems of the present invention, various effects including the following items can be expected. However, the present invention is not achieved by achieving all of the following effects.

[0025] According to one embodiment of the present invention, a biosignal measuring patch device forms a slit between a housing and a biosignal sensing sensor, so that the substrate can deform in response to bending and movement of human skin, but the sensor for measuring biosignals can be closely attached to the skin and contact force can be maintained.

[0026] In addition, the present invention has an advantage in that it can accurately detect whether the sensor is in close contact with the skin by using the skin-attached sensing electrodes, and can immediately respond to the patch falling off the skin.

[0027] Furthermore, the present invention is capable of sensing not only electrocardiogram signals, but also breathing, snoring, turning over in bed, etc., and by sounding an alarm if the breathing signal or electrocardiogram signal is reduced, monitoring is easy and emergency situations can be dealt with quickly.

[0028] In addition, the present invention prevents the second area from being separated from the skin due to the gravity of the housing by arranging the first area of ​​the substrate on which the housing is arranged at the bottom and the second area on which the sensor is arranged at the top.

[0030] The present invention can be modified in various ways and can have various embodiments, but specific embodiments are illustrated in the drawings and will be described in detail by the description of the invention. However, they do not limit the present invention to the specific embodiments, and should be understood to include all modifications, equivalents, or alternatives within the spirit and technical scope of the present invention. In describing the present invention, the same identification symbols are used for the same components even if they are illustrated in other embodiments.

[0031] Hereinafter, an embodiment of the present invention will be described in detail with reference to the attached drawings. When describing with reference to the drawings, the same or corresponding components are denoted by the same reference numerals, and duplicate descriptions thereof will be omitted.

[0032] In the following embodiments, terms such as first and second are not used in a limiting sense but are used only to distinguish one component from another component.

[0033] In the following embodiments, a singular expression includes a plural expression unless otherwise clearly indicated in the context.

[0034] In the following embodiments, the terms "comprise" or "have" mean the presence of features or components described in the specification, without precluding the possibility that one or more other features or components may be added.

[0035] In the drawings, the size of components may be exaggerated or reduced for the convenience of explanation. For example, the size and thickness of each component shown in the drawings are arbitrarily shown for the convenience of explanation, and the present invention is not necessarily limited to what is shown in the drawings.

[0036] In the following embodiments, the x-axis, y-axis, and z-axis are not limited to the three axes on a Cartesian coordinate system, but are also interpreted in a broad sense including them. For example, the x-axis, y-axis, and z-axis may be mutually orthogonal, but may not be mutually orthogonal and may refer to mutually different directions.

[0037] When an embodiment can be embodied in other forms, the order of certain steps may be performed differently than that described, for example, two steps described as successive may be performed substantially simultaneously or may be performed in the opposite order to that described.

[0038] The terms used in this application are merely used to describe certain embodiments and are not intended to limit the present invention. In this application, terms such as "comprise" or "have" are intended to specify the presence of a feature, number, step, operation, component, part, or combination thereof described in the specification, and should be understood not to preclude the presence or addition of one or more other features, numbers, steps, operations, components, parts, or combinations thereof.

[0039] In the present disclosure, a monitoring device is an electronic device including a processor, a memory, and a communication module, such as a desktop, a smart phone, a mobile phone, a laptop, a tablet, etc. The monitoring device can communicate with a biosignal measuring patch device and receive data related to the biosignal measured by the biosignal measuring patch device.

[0040] Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.

[0041] FIG. 2 is a plan view of one embodiment of the biosignal measurement patch device of the present invention, FIG. 3A is a right side view of the biosignal measurement patch device according to the first embodiment, FIG. 3B is a right side view of the biosignal measurement patch device according to the second embodiment, FIG. 4 is a bottom view illustrating the skin-attached sensing electrode 140 arranged in the first region 110 in FIG. 2, and FIG. 5 is a bottom view illustrating the skin-attached sensing electrode 140 arranged around the sensor in FIG. 2.

[0042] As shown in these drawings, an embodiment of the present invention also includes a substrate 100 made of a flexible material, a housing 200 disposed on the substrate 100, and a sensing electrode 300 for measuring a biosignal. In FIG. 3A, the sensing electrode 300 for measuring a biosignal is located on the upper part of the substrate 100, but as shown in FIG. 3B, the sensing electrode 300 for measuring a biosignal may be located on the lower part depending on a sensing signal. The sensing electrode 300 for measuring a biosignal, which senses a voltage (e.g., electrocardiogram) and measures a biosignal, may be located on one side of the substrate so as to be attached to the skin (lower end). If the sensing electrode 300 for measuring a biosignal includes a module (such as an acoustic module), it may be located on the front side as shown in FIG. 3A.

[0043] The substrate 100 is made of a flexible material, and is worn so as to bend flexibly as the human body bends and to be in close contact with the skin. The substrate 100 is configured to supply electricity to a sensor and transmit a sensor signal, and a circuit may be formed on the substrate 100. The substrate 100 may also be made of a flexible material, a flexible printed circuit board (FPCB). The substrate 100 may also be made of a plurality of substrates, and may be formed in a form in which a general PCB is bonded to the FPCB. In this case, it is preferable that the PCB has a shape that can be easily warped and is formed to include a narrow portion. The FPCB may be a film-shaped material or a waterproof fiber material.

[0044] According to an embodiment of the present invention, the substrate 100 may be divided into a first region 110 and a second region 120. The housing 200 may be disposed in the first region 110, and the sensing electrode 300 for measuring a biosignal may be disposed in the second region 120. That is, the substrate 100 may be divided such that the housing 200 is disposed on one side and the sensing electrode 300 for measuring a biosignal is disposed on the other side. The sensing electrode 300 for measuring a biosignal may be disposed on a surface that contacts the skin. The sensing electrode 300 for measuring a biosignal may also be disposed on the front or back surface of the substrate 100 as shown in FIGS. 3A and 3B.

[0045] A housing arrangement hole 111 may be formed through the first region 110 for arrangement of the housing 200. The housing arrangement hole 111 allows electrical connection between the parts of the components provided in the housing 200 that need electrical connection with the human body. In addition, the housing arrangement hole 111 is formed to correspond to the overall shape or a part of the shape of the housing 200.

[0046] In addition, a housing fixing hole 112 may be formed in a portion surrounding the housing arrangement hole 111. The housing 200 and the substrate 100 may be coupled together by tying a knot using the housing fixing hole 112 or by inserting a protrusion formed on the housing 200 into the housing fixing hole 112.

[0047] In addition, a separation part 113 may be formed on one side of the housing arrangement hole 111. Although the separation part 113 is shown in Fig. 4, it may also be formed at a portion where the housing 200 is electrically connected to an electrical component other than the housing 200. The separation part 113 is formed in a longitudinal hole shape on the substrate 100, and an end of the hole is formed to penetrate the housing arrangement hole 111. Therefore, even if the substrate 100 is deformed, the external force that causes the deformation is not transmitted to the inside of the housing 200 by the separation part 113, thereby improving durability.

[0048] One or more sensing electrodes 300 for measuring biological signals may be disposed in the second region 120. The region of the substrate 100 other than the second region 120 also constitutes the first region 110. The sensing electrodes 300 for measuring biological signals will be described later.

[0049] In addition, a slit 130 may be formed in a portion defined by the first region 110 and the second region 120 along the direction of definition. The slit 130 may also be formed along the boundary between the first region 110 and the second region 120. That is, the first region 110 and the second region 120 are defined in the vertical direction in FIG. 2, and the slit 130 may also be formed in the vertical direction. A plurality of slits 130 may be formed in series, and therefore, a bridge 131 may be formed between the slits 130 to connect the first region 110 and the second region 120. Although the slit 130 is shown in one direction for convenience, it goes without saying that a plurality of slits 130 may be embodied at various angles.

[0050] According to an embodiment of the present invention, the first region 110 of the substrate 100 in which the housing 200 is disposed is also disposed at the bottom, and the second region 120 in which the sensor is disposed is also disposed at the top. The housing 200 is formed of a material with high rigidity in order to protect the internal components, and therefore, the weight of the housing 200 body and the weight of the internal components are added, and the housing 200 is heavier than other parts. Therefore, when the first region 110 and the second region 120 are disposed horizontally, the first region 110 and the second region 120 may be lifted up from the skin one after another due to the weight of the housing 200. Similarly, when the first region 110 is located at the top and the second region 120 is located at the bottom, the first region 110 and the second region 120 may be lifted up from the skin one after another. Therefore, by attaching the first region 110 to the bottom and the second region 120 to the top, the second region 120 may be prevented from being separated from the skin due to the weight of the housing 200. Here, the lower part is the leg side direction and the upper part is also the head side direction.

[0051] The present invention also includes an alarm unit (not shown) in the housing 200 or the substrate 100. The alarm unit is also controlled to generate a visual and / or audio alarm via a lamp or speaker if the magnitude or frequency of the respiratory signal or electrocardiogram (ECG) signal is reduced.

[0052] In addition, the substrate 100 may further include a skin-attached sensing electrode 140. The skin-attached sensing electrode 140 detects a potential difference with a reference electrode 210, which will be described later, and can determine whether the biosignal measurement patch of the present invention is attached properly and its quality by using the difference between the capacitance when the electrode is in contact with the human body and the capacitance when the electrode is not in contact with the human body or is in poor contact with the human body.

[0053] Skin-attached sensing electrodes 140 are illustrated in Figures 4 and 5. Skin-attached sensing electrodes 140 are also attached to one side of substrate 100, the side that contacts the human body, as shown in Figure 3A. Skin-attached sensing electrodes 140 are also attached to the back side of substrate 100, the side that contacts the human body, as shown in Figure 3B.

[0054] 4, in one embodiment, the skin-attached sensing electrode 140 may be disposed in the first region 110. In this case, however, the skin-attached sensing electrode 140 may be disposed on the side of the slit 130. That is, the distance from the skin-attached sensing electrode 140 to the slit 130 is formed closer than the distance from the center of the housing 200. This is because the second region 120 is the region where accurate attachment is required, and therefore the skin-attached sensing electrode 140 is disposed closer to the second region 120. Furthermore, because the reference electrode 210 is provided in the housing 200, a sufficient distance is required between the skin-attached sensing electrode 140 and the reference electrode 210 to increase the accuracy of the potential difference measurement.

[0055] As another embodiment of the arrangement of the skin-attached sensing electrodes 140, as shown in Fig. 5, a plurality of skin-attached sensing electrodes 140 may be arranged at positions surrounding the sensing electrodes for measuring biological signals. Furthermore, when a plurality of sensors are arranged, the sensors and the skin-attached sensing electrodes 140 may be arranged alternately. It is also possible for the skin-attached sensing electrodes 140 to transmit information related to electrodes that are determined not to be attached to the human body, i.e., the positions of the electrodes, to an external monitoring device via a communication unit. Through this, it is possible to sense which parts are raised or not attached.

[0056] 4, the battery 150 may be mounted to the substrate 100 and protected by the housing 200 or may be mounted within the housing 200. The drawing shows the battery 150 mounted to the substrate 100.

[0057] As shown in Fig. 4, the housing 200 is disposed in the housing arrangement hole 111 in the first region 110 of the substrate 100. The housing 200 also includes a communication unit for collecting information measured by the battery 150 and the sensor and transmitting the collected information to the monitoring device. The communication unit also includes an ID for Bluetooth connection. The biometric patch device according to the embodiment of the present disclosure further includes an alarm unit and a control unit for controlling the aforementioned electrical components.

[0058] The housing 200 is also formed by plastic injection molding, and has a certain thickness since the battery 150 and the like are disposed inside. Therefore, since it protrudes from other parts of the substrate 100, it has a structure that makes it easier to adhere to the human body when pressed against the human body. Therefore, if a breathing sensor that detects sound is provided, the breathing sensor is also provided in the housing 200.

[0059] The housing 200 may also be provided with a reference electrode 210. The reference electrode 210, together with the above-mentioned skin-attached sensing electrode 140, is for measuring the attachment quality of the bio-signal patch of the present invention. The reference electrode 210 is also attached to one side of the substrate 100, i.e., the side that contacts the human body.

[0060] The sensing electrode 300 for measuring a biological signal can measure a biological signal, and may include, for example, a respiration sensor, an electrocardiogram (ECG) sensor, a snoring sensor, a rolling sensor, an electromyogram sensor, etc. The sensing electrode 300 for measuring a biological signal may be realized by three electrodes as shown in the drawings, but is not limited thereto, and may be realized by two or more electrodes. The sensing electrode 300 for measuring a biological signal may be formed by a sensor electrode or a semiconductor.

[0061] An electrocardiogram (ECG) sensor is a sensor that uses electrocardiogram electrodes to sense potential differences caused by contraction and expansion of the heart. The ECG sensor can detect heart rate, arrhythmia, and the like by using the sensed potential differences.

[0062] A respiration sensor that detects sound must be attached closely to the human body, and therefore is also provided on the housing 200, which is easier to attach to than the substrate 100 when compressed. A respiration sensor that detects a capacitor is a sensor that measures the change in capacitance as the volume of the thorax contracts and expands during breathing, and can also be measured using the skin-attached sensing electrode 140. The period of change in capacitance can be used to calculate the number of breaths per hour.

[0063] The snore sensor is a sensor that recognizes snoring sounds and apnea states using an acoustic sensor. The turnover sensor is an acceleration sensor or a gyro sensor that detects when the user's posture changes and can measure the degree of turning depending on the degree of posture change. The electromyogram sensor can detect electrical signals required for muscle movement by measuring the potential difference between electromyogram (EMG) electrodes, similar to electrocardiogram electrodes. In addition to these, it also includes a temperature sensor and an impedance sensor.

[0064] The battery 150, the skin-attached sensing electrode 140 and the biosignal measuring sensing electrode 300 are electrically connected to the internal components of the housing 200 by the conductors 310 on the substrate 100, and in particular are also connected via the connector 320. The connector 320 is provided on the separation portion 113 side of the substrate 100 described above and is protected from external forces. It is advantageous that the separation portion 113 is formed on both sides of the connector 320.

[0065] An adhesive patch 400 may be attached to the back surface of the substrate 100. The adhesive patch 400 may be a patch with adhesive applied to one side as shown in FIG. 3A, or may be formed of an adhesive film. The adhesive patch 400 is formed to be larger than the substrate 100, to protect the substrate 100, and to allow the edge portion to be attached to the human body. Thus, the back surface of the adhesive patch 400 is non-adhesive, and the front surface of the adhesive patch 400 is formed to be adhesive. A release paper is attached to the front surface of the adhesive patch 400, and the release paper can be removed just before use. The adhesive patch 400 is formed in a portion of the substrate 100 as shown in FIG. 3B, but is not limited thereto and may be modified in various ways.

[0066] Hereinafter, a method of using a patch device for measuring a biological signal according to an embodiment of the present invention will be described. The method of using the patch device for measuring a biological signal according to the present invention relates to the method of using the patch device for measuring a biological signal described above, and the same names and reference numerals are understood to have the same meanings. However, it is not necessary to implement the patch device for measuring a biological signal by including all of its components in order to fall within the scope of the present invention, and even if only some of its components are used, it may fall within the scope of the present invention.

[0067] FIG. 6 is a flow chart of a method for using a vital sign measurement patch device according to one embodiment.

[0068] The method of using the biosignal measuring patch device includes a substrate placement step (S110) of placing one side of the substrate 100, on which the housing 200 and the sensing electrode 300 for measuring a biosignal are arranged, on the user's heart, and an attachment step (S120) of attaching the substrate 100 to the user's skin using the adhesive patch 400 attached to the other side of the substrate 100. Here, the heart does not mean the exact location of the heart, but includes any part of the chest adjacent to the heart. Here, the one side of the substrate is also the surface on which the sensing electrode 300 for measuring a biosignal is arranged.

[0069] FIG. 7 is an exemplary diagram of a vital sign measuring patch device attached to a user's heart area according to one embodiment.

[0070] In the substrate placement step, the substrate 100 can be placed so that the first region 110 of the substrate 100 is located lower than the second region 120. As shown in Fig. 7, the biosignal measurement patch device T can be attached near the user's heart in a direction in which the housing 200 is located lower than other parts on the substrate 100. The substrate 100 can be attached to the user's heart so that the housing 200 is located lower than other parts on the substrate 100. This is because the weight of the housing 200 is relatively heavy on the substrate 100, and the second region 120 of the substrate 100 is prevented from lifting up from the skin due to the weight of the housing 200.

[0071] The present invention has been described above with reference to the embodiments shown in the drawings, but they are merely examples.
