Description

의료용 모니터링 전극 {medical-treatment electrode}Medical monitoring electrode {medical-treatment electrode}

본 발명은 심전도(ECG;Electrocardiogram), 근전도(EMG;Electromyog ram), 뇌파 및 신경계 신호를 정밀 측정하기 위하여 사용되는 의료용 모니터링 전극에 관한 것으로서, 니들과 전선을 땜으로 연결하지 않고 압착구로 체결 구성된 의료용 모니터링 전극에 관한 것이다.The present invention relates to a medical monitoring electrode used for precise measurement of electrocardiogram (ECG), electrocardiogram (EMG), electroencephalogram and nervous system signals, and is a medical device configured to be fastened by a crimp without connecting a needle and an electric wire It relates to a monitoring electrode.

근육의 활동전위를 나타내는 근육의 활동전류를 근전도라고 하고, 심근의 흥분은 정맥동(靜脈洞)에서 일어나 심방 ·심실 방향으로 나아가므로 이 흥분을 임의의 두 점에서 전류계(심전계)에 유도하면 심장의 활동전류가 그래프로 묘사되는데, 이와 같이 해서 얻은 것이 심전도이며 심장질환의 진단에 매우 중요하다. The action current of the muscle, which represents the action potential of the muscle, is called EMG, and the excitation of the myocardium rises in the sinus sinus and goes to the atrial and ventricular directions. The active current is depicted graphically, which is obtained by electrocardiography and is very important for the diagnosis of heart disease.

상기와 같은 심전도 및 근전도와 같은 생체신호 및 신체리듬을 측정하기 위해서 버튼타입과 집게 타입의 전극이 널리 사용되고 있다. Button-type and forceps-type electrodes have been widely used to measure biosignals and body rhythms such as electrocardiogram and electromyography.

그러나, 각종 질병의 확대, 세분화 및 현대의학이 고도로 발달함에 따라서 생체신호 및 신체리듬을 보다 정확하게 측정하여야 하는 필요성이 대두되고 있는데, 상기와 같은 버튼타입과 집게타입의 전극은 생체신호를 정확하게 측정하기에 부족한 문제점이 있었다.However, as the expansion, segmentation, and modern medicine of various diseases are highly developed, there is a need to measure bio signals and body rhythms more accurately. The button-type and tong-type electrodes as described above accurately measure bio signals. There was a scarce issue.

이러한 문제점 때문에 근래에는 보다 정확한 생체신호를 측정하기 위해서 바늘타입의 전극을 널리 사용하고 있는 실정이다. 특히 환자의 수술시 미세한 생체 신호의 정밀 측정 및 모니터링 하기 위해 상기와 같은 바늘타입의 전극을 사용하고 있다.Due to these problems, in recent years, needle type electrodes have been widely used to measure more accurate bio signals. In particular, the needle-type electrode is used as described above to precisely measure and monitor minute bio signals during surgery of a patient.

수술과정 중 환자의 생체신호를 정밀 측정하여 이를 기록함으로써 만일, 의료사고가 발생하였을 경우 상기 전극을 통해 기록된 환자의 생체신호를 바탕으로 수술 시술자의 과실의 분석 판별할 수 있기 때문에 수술과정에서도 널리 사용되고 있다.By precisely measuring and recording the patient's biosignal during the procedure, if a medical accident occurs, it is widely used in the procedure because it is possible to analyze the error of the operator based on the patient's biosignal recorded through the electrode. It is used.

상기와 같은 바늘타입의 전극은 도 1과 같이 신체 측정부위에 삽입하는 니들(needle)(10)과, 상기 니들(10)과 측정장비를 전기적으로 연결하는 전선(20)으로 구성되는데, 상기 니들(10)과 전선(20)은 전기적, 물리적으로 연결 고정이 용이한 땜(30)으로 연결하여 사용하고 있다.The needle-type electrode as described above is composed of a needle (needle) 10 to be inserted into the body measurement site as shown in Figure 1, and the wire 20 for electrically connecting the needle 10 and the measurement equipment, the needle 10 and the electric wire 20 are connected and used by the solder 30 which is easy to connect and fix electrically and physically.

이러한 니들(10)과 전선(20)을 연결하기 위한 땜(30)은 통상 은(Ag), 납(Pb), 구리(Cu)를 포함하고 있기 때문에 중금속에 의한 인체에 해를 가할 뿐만 아니라, 환경오염을 발생시키는 원인이 되고 있는 실정이다.Since the solder 30 for connecting the needle 10 and the electric wire 20 usually contains silver (Ag), lead (Pb), and copper (Cu), it not only harms the human body by heavy metals, It is a situation that causes environmental pollution.

또한, 크기가 매우 작은 니들(10)과 전선(20)을 일일이 땜으로 체결하여야 하기 때문에 대량생산이 불가능한 문제점이 있었다.In addition, since the needle 10 and the wire 20 having a very small size must be fastened by soldering, there was a problem that mass production was impossible.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출한 것으로서, 중금속으로 구성된 땜을 사용하지 않고 니들과 전선을 체결 연결함으로써 인체에 해를 가하지 않고 환경오염을 발생시키지 않으며, 대량생산이 가능한 의료용 모니터링 전극을 제공하는 것이 본 발명의 목적이다.The present invention has been made to solve the above problems, by connecting and connecting the needle and the wire without using a solder made of heavy metal does not harm the human body and does not cause environmental pollution, medical monitoring electrode capable of mass production It is an object of the present invention to provide.

상기의 목적을 달성하기 위하여 본 발명은

As described above, while the wing pieces 102 on both sides of the body 101 are bent into the body 101, the needle 110 and the wire 120 are firmly connected to each other.

이때, 상기 압착구(100)의 고정편(103)이 몸체(101) 내측으로 소정각도 꺽여있기 때문에 날개편(102)이 꺽이면서 상기 고정편(103)이 자연스럽게 니들(110)과 전선(120)의 사이로 삽입되면서 도 4와 같이 니들(110)과 전선(120)을 감싸면서 압착되어 더욱 견고하게 체결된다.At this time, since the fixing piece 103 of the pressing hole 100 is bent at a predetermined angle to the inside of the body 101, the wing piece 102 is bent and the fixing piece 103 naturally has the needle 110 and the electric wire 120. ) While being inserted between the needle 110 and the wire 120 as shown in FIG.

또한, 도 3과 같이 고정편(103)의 단부에는 압입구(104)가 형성되어 있기 때문에 압착과정에서 상기 압입구(104)가 니들(110)과 전선(120)에 강하게 압입되어 더욱 견고하게 체결되도록 한다. 상술한 바와 같이 전선(120)은 여러 가닥의 가는 세선을 꼬아 구성한 것으로써, 상기 압입구(104)가 꼬안 세선의 사이에 압입되고, 상기 압입구(104)가 니들(110)의 표면에 압입됨으로써 니들(110)과 전선(120)이 더욱 강하게 체결되는 것이다.In addition, since the indentation hole 104 is formed at the end of the fixing piece 103 as shown in FIG. 3, the indentation hole 104 is strongly pressed into the needle 110 and the electric wire 120 in the pressing process. To be tightened. As described above, the wire 120 is formed by twisting a plurality of thin fine wires, and the indentation hole 104 is press-fitted between the fine eye wires, and the indentation 104 is press-fitted on the surface of the needle 110. By doing so, the needle 110 and the wire 120 is more strongly fastened.

도면에는 도시하지 않았으나, 상기 날개편(102)에 소정 곡률의 만곡부(미도시)를 형성함으로써 압착구(100)를 압착할 때 만곡부가 형성된 날개편(102)이 니들(110)과 전선(120)에 밀착된 상태로 압착되도록 구성하는 것이 바람직하다.Although not shown in the drawing, the blade piece 102 formed with the curved portion when the crimp 100 is crimped by forming a curved portion (not shown) having a predetermined curvature in the blade piece 102 has a needle 110 and an electric wire 120. It is preferable to comprise so that it may be crimped in close contact.

또한, 도 2와 같이 압착구(100)를 이용하여 니들(110)과 전선(120)을 체결 연결한 후 연결부위에 수축튜브 등으로 마감처리하는 것이 바람직하다.In addition, it is preferable that the needle 110 and the electric wire 120 are fastened and connected to each other by using a crimping hole 100, and then finished with a contraction tube.

상기와 같이 구성된 본 발명은 중금속 소재의 땜을 사용하지 않고 니들과 전선을 압착구를 이용하여 체결 연결하기 때문에 인체에 해가 없고, 환경오염을 발생시키지 않으며, 구조가 간단하고 체결방법이 간단하기 때문에 대량생산이 가능하여 생산비용을 획기적으로 절감할 수 있다.The present invention configured as described above has no harm to the human body, does not cause environmental pollution, since the needle and the electric wire are fastened and connected without using a solder of heavy metal material, the structure is simple and the fastening method is simple. Therefore, mass production is possible, which can drastically reduce the production cost.
