본 발명은 생체신호 측정용 패치형 전극에 관한 것으로서, 더욱 상세하게는 전극체가 인체의 피부에 안정적인 부착상태가 유지되어질 수 있도록 함과 함께 데이타 저장 및 전원공급 기능을 갖는 착탈식 본체가 구비된 패치형 전극 구조에 관한 것이다.The present invention relates to a patch-type electrode for measuring a bio-signal, and more particularly, to a patch-type electrode structure having a detachable body having a data storage and a power supply function while allowing the electrode body to be maintained in a stable attachment state on the human skin. It is about.

대표적인 생체 정보 중의 하나인 심전도(ElectroCardioGram : ECG)는 심장의 박동에 의해 심장근육이 수축 확장되면서 발생되는 활동전류를 기록한 것으로, 신체의 피부에 전극을 부착시켜 심장 근육의 수축에 따른 활동 전류를 측정한 후 측정된 전류데이터를 그래프로 묘사하는 것이다.ElectrocardioGram (ECG), one of the representative biometric information, records the active current generated when the heart muscle contracts and expands due to the beating of the heart, and attaches an electrode to the skin of the body to measure the active current according to the contraction of the heart muscle. The graph then depicts the measured current data.
구체적으로, 심장 박동에 의해 심장 근육이 수축 이완할 때 발생되는 활동 전위는 심장으로부터 온몸으로 전달되는 전류를 일으키며, 이 전류는 몸의 위치에 따라 전위차를 발생시키는데 이 전위차는 인체의 피부에 부착된 표면 전극을 통해 검출하여 기록할 수 있다.Specifically, the action potential generated when the heart muscle contracts and relaxes due to the heartbeat causes an electric current transmitted from the heart to the whole body, which generates an electric potential difference according to the position of the body, which is attached to the skin of the human body. It can be detected and recorded through the surface electrode.
이와 같은 심전도는 심장의 이상 유무 확인하는데 이용되고 있으며, 협심증, 심근경색 및 부정맥 등 심장계 질환의 진단에 기본적인 측정방법으로 이용되고 있다.Such electrocardiograms are used to check for abnormalities of the heart and are used as a basic measurement method for diagnosing cardiac diseases such as angina pectoris, myocardial infarction and arrhythmia.
일반적으로 심장의 전기적 이상을 측정하기 위하여 임상에서 사용하는 전극 유도법은 심장의 동방결절에서 발생한 전기적 자극이 좌우 심실과 좌우 심방으로 전도되면서 발생하는 생체 전위를 측정하는 것으로 2개 이상의 전극을 인체 표면에 부착하여 측정한다.In general, the electrode induction method used in the clinical practice to measure the electrical abnormality of the heart is to measure the biopotential generated when the electrical stimulation generated in the ipsilateral node of the heart is conducted to the left and right ventricles and the left and right atria. It is attached and measured.
이처럼 전극을 이용한 측정법으로는 사지 전극 유도법과 2전극 측정법이 주로 이용되고 있다.As such, the limb electrode induction method and the two-electrode measurement method are mainly used as the measurement method using the electrode.
사지 전극 유도법은 전자기학적으로 선적분의 경로가 길면 길수록 큰 전위를 측정할 수 있다는 점을 이용하여 신체의 양쪽팔과 다리에 전극을 부착하고 이를 케이블로 심장 전기 활동 측정 장치에 연결하여 심장의 전기적 활동을 측정토록 하는 방법이다. 이러한 사지 전극 유도법의 경우 선적분의 경로가 길면 길수록 큰 전위를 측정할 수 있는 특성을 가지기 때문에 소형화가 어렵다는 문제점과 잡음에 민감하다는 단점이 있다.The limb electrode induction method uses the fact that the longer the route of shipment is, the greater the potential can be measured, and the electrode is attached to both arms and legs of the body and the cable is connected to a cardiac electrical activity measuring device. It is a method to measure. In the case of the limb electrode induction method, since the longer the route of the shipment, the larger the potential can be measured, there is a problem that it is difficult to miniaturize and is sensitive to noise.
그리고 2전극 측정법은 신축성을 가지는 밴드를 이용하여 가슴 부위에 전극을 부착하여 심장의 전기적 활동을 측정하는 방법이다. 이러한 2전극 측정법의 경우 신축성을 가지는 밴드를 가슴 부위에 착용시 가슴 압박감 때문에 장시간 착용하기가 어렵다는 문제점이 있다.The two-electrode measuring method is a method of measuring the electrical activity of the heart by attaching an electrode to the chest area using an elastic band. In the case of the two-electrode measurement method, there is a problem in that it is difficult to wear the elastic band for a long time because of the feeling of pressure on the chest.
또한, 최초 부착시 사용자의 실수로 인해 느슨하게 부착되거나 장시간 사용으로 인해 전극의 습도가 저감될 경우 측정되는 심장박동 신호의 품질이 떨어진다는 문제점이 있다.In addition, there is a problem in that the quality of the heart rate signal measured when the electrode is loosely attached due to a user's mistake when the first attachment or the humidity of the electrode is reduced due to long use.
이와 같은 종래의 심장박동 신호를 측정하는 장치에서 발생되는 문제점들을 해결할 수 있는 심장박동 신호 측정장치들이 개발되었다.Heart rate signal measuring apparatus has been developed that can solve the problems occurring in the conventional device for measuring the heart rate signal.

이 기술의 경우 종래의 사지 전극 유도법에 비해 소형화된 무선 전극 패치를 이용한 심장 전기 활동 신호를 지속적으로 모니터링 할 수 있다는 이점이 있다. 하지만 무선 전극 패치를 이용함으로써, 신호 처리 및 전송부로 부터 생성되어 증폭된 생체 전위 신호를 무선으로 전송받을 수 있는 심전도 측정 기기에만 적용이 가능하게 되는 문제점이 있었다.This technique has the advantage of continuously monitoring cardiac electrical activity signals using a miniaturized wireless electrode patch compared to conventional limb electrode induction. However, by using the wireless electrode patch, there was a problem that can be applied only to the electrocardiogram measuring device that can receive the amplified biopotential signal generated from the signal processing and transmission unit by wireless.

한편, 본 실시 예에서의 전극부(20) 및 신호라인(30)은 통전성 향상을 위한 염화은(AgCl) 재질로 형성됨이 바람직하다.On the other hand, the electrode unit 20 and the signal line 30 in the present embodiment is preferably formed of a silver chloride (AgCl) material for improving the electrical conductivity.
특히, 도 8의 패치형 전극체의 배면측 분해 사시도에서 나타내어지는 바와 같이 신호라인(30)의 내부식성과 경도를 향상시키기 위해 경화도료 재료로 이루어진 UV코팅층(35)이 구성되어짐이 바람직하다. 미설명 부호 41은 스냅단추(40)의 고정을 위해 부직포층(10)의 반대면에 결합되어지는 단추 고정구를 나타낸다.In particular, as shown in the back side exploded perspective view of the patch-type electrode body of FIG. 8, it is preferable that a UV coating layer 35 made of a cured coating material is formed to improve the corrosion resistance and hardness of the signal line 30. Reference numeral 41 denotes a button fixture that is coupled to the opposite side of the nonwoven layer 10 to secure the snap button 40.
이와 같은 구성을 이루는 본 발명 패치형 전극의 사용에 따른 작용효과를 살펴보기로 한다.The effect of using the patch-type electrode of the present invention constituting such a configuration will be described.
본 발명의 패치형 전극은 먼저 부직포 패치의 중앙에 본체(70)를 결합시킨 상태에서 패치를 도 11에서와 같이 측정할 실험자의 신체 가슴부위에 부착시킴으로서 패치가 본체(70)를 감싸는 형태를 이루어 본체(70)의 외부노출이 방지되는 가운데 생체 전위 신호를 측정 및 저장하게 되는 것이다.The patch-type electrode of the present invention forms a form in which the patch surrounds the main body 70 by attaching the patch to the body chest of the experimenter to be measured as shown in FIG. 11 while the main body 70 is coupled to the center of the nonwoven patch. While the external exposure of 70 is prevented, the biopotential signal is measured and stored.
즉, 패치는 각 전극부(20)에 형성된 접착층(60)과 부직포층(10)의 전면에 도포된 접착제의 접착력에 의해 인체의 가슴부위 등 특정 부위에 밀착된 형태로 부착되어질 수 있게 되는데, 이와 같이 패치의 가슴 부착이 이루어지기 전에 먼저 스냅단추(40)를 이용하여 본체(70)를 패치의 중심에 결합시키게 되면 본체(70)에서 제어부(74)의 제어신호에 의해 내장 전원부(73)로 부터 인가되는 동작전류가 스냅단추(40) 및 신호라인(30)을 통해 전극부(20)에 전달되어짐으로서 전극부(20)에서는 생체 전위 신호의 변화를 측정하게 된다.That is, the patch may be attached in a form in close contact with a specific part such as the breast part of the human body by the adhesive force of the adhesive layer 60 and the non-woven fabric layer 10 formed on the front of the electrode portion 20, As such, when the main body 70 is coupled to the center of the patch using the snap button 40 before the patch is attached to the chest, the internal power supply unit 73 is controlled by the control signal of the controller 74 in the main body 70. Since the operating current applied from the transfer to the electrode unit 20 through the snap button 40 and the signal line 30, the electrode unit 20 measures the change in the biopotential signal.
그리고, 전극부(20)에서 측정된 전류신호(심전도신호)는 신호라인(30)을 통해 스냅단추(40)와 통전상태의 본체(70)로 전달되어지게 되며, 본체(70)에서는 전달된 전류신호가 AMP(76)에서 증폭되어진 후 제어부(74)의 제어에 의해 데이터 저장부(72)에 저장되어지게 된다.Then, the current signal (electrocardiogram signal) measured by the electrode unit 20 is transmitted to the main body 70 in the energized state with the snap button 40 through the signal line 30, the main body 70 The current signal is amplified by the AMP 76 and then stored in the data storage unit 72 under the control of the controller 74.
따라서, 정해진 측정시간 동안의 신체 전류신호가 데이터 저장부(72)에 저장되어지게 됨으로 측정 신호의 변화를 파악할 수 있게 된다.Therefore, the body current signal for the predetermined measurement time is stored in the data storage unit 72, so that the change in the measurement signal can be grasped.
특히, 본 발명에서의 본체(70) 내에는 가속도센서(75)가 함께 구성되어져 있기 때문에 가속도센서(75)의 기울기 측정 데이타가 함께 데이터 저장부(72)에 저장되어짐으로서, 저장된 데이터의 확인을 통해 해당 전류신호가 실험자의 어떤 자세에 따른 측정 결과인지를 함께 확인할 수 있게 된다.In particular, since the acceleration sensor 75 is configured together in the main body 70 in the present invention, the tilt measurement data of the acceleration sensor 75 is stored together in the data storage unit 72, thereby confirming the confirmation of the stored data. Through this, it is possible to check whether the current signal is the measurement result according to the posture of the experimenter.
한편, 일정 시간동안 측정작업이 완료되면 패치형 전극을 신체로 부터 떼어낸 후, 본체(70)를 스냅단추(40)로 부터 분리하여 본체(70) 일 측에 구비된 유에스비 소켓(미도시)에 유에스비 등과 같은 데이터 전송장치를 연결하여 데이터 저장부(72)에 저장된 데이터를 외부로 전송하여 측정 데이터를 확인 및 분석할 수 있게 된다.On the other hand, when the measurement is completed for a certain time, after removing the patch-type electrode from the body, the main body 70 is separated from the snap button 40 to the USB socket (not shown) provided on one side of the main body 70 By connecting a data transmission device such as a USB network, the data stored in the data storage unit 72 may be transmitted to the outside to check and analyze the measurement data.
따라서, 본 발명의 생체신호 측정용 패치형 전극은 인체의 피부에 견고하게 부착된 상태를 이루게 됨으로 신체 움직임에 악영향을 미치지 않게 됨은 물론 측정 데이터가 저장되어지는 본체(70)의 착탈이 용이한 구조를 이룸으로서 제품의 신뢰성을 극대화할 수 있게 됨을 알 수 있다.Therefore, the patch-type electrode for measuring the bio-signals of the present invention has a structure that is firmly attached to the skin of the human body, thereby not adversely affecting body movements, and of course, the detachable structure of the main body 70 in which the measurement data is stored. This shows that the reliability of the product can be maximized.
한편, 도 9의 응용 예에서 나타내어진 바와 같이 부직포층(10)의 저면에는 전극부(20)로 전원 공급을 위한 페이퍼 배터리 형태의 외장 전원부(80)가 부착 구비되되, 상기 외장 전원부(80)는 스냅단추(40)와 접촉에 따른 통전이 이루어지는 구조를 이루도록 한 것이다.Meanwhile, as shown in the application example of FIG. 9, an external power supply unit 80 in the form of a paper battery for supplying power to the electrode unit 20 is attached to the bottom surface of the nonwoven fabric layer 10. Is to achieve a structure in which the energization according to the contact with the snap button 40 is made.
이와 같은 구조를 이루게 되면, 상기 일 실시 예에서와 같이 본체(70)에 별도의 내장 전원부(73)를 설치할 필요가 없게 됨으로 본체(70)의 크기를 더욱 줄일 수 있게 되어 제품의 컴팩트화를 이룰 수 있는 효과를 나타낸다.When such a structure is achieved, it is not necessary to install a separate built-in power supply unit 73 in the main body 70 as in the embodiment, thereby further reducing the size of the main body 70 to achieve compactness of the product. It can have an effect.
도 10은 본 발명의 다른 실시 예에 따른 밴드형태로 제작되어진 패치형 전극 구조체의 구조를 나타낸 것으로서, 상기 방사형 외에도 다양한 형태로 패치 전극의 제작이 가능하게 됨을 알 수 있다.Figure 10 shows the structure of a patch-type electrode structure manufactured in a band form according to another embodiment of the present invention, it can be seen that it is possible to manufacture the patch electrode in various forms in addition to the radial.
