As the hemostatic method, a hemostatic method is used to compress the perforated area of blood vessels of a patient using a hand, a sandbag, or a compression machine. do.
그러나, 상기 압박법은 지혈 시간이 과다하게 소요될 뿐만 아니라, 시술 시간 동안 환자가 움직이지 않은 상태로 있어야 하므로 환자의 거동에 많은 제약이 따른다. 특히, 지혈시 천공 부위가 장시간 동안 압박되어 혈류가 눌려진 상태가 되므로 예를 들면, deep vein thrombosis, pulmonary embolization, hematoma 등과 같은 의료적 부작용을 유발하는 한 요인이 된다.However, the compression method not only takes excessive time for hemostasis, but also requires a lot of constraints on the patient's behavior since the patient must remain stationary during the procedure. In particular, during hemostasis, the perforated region is compressed for a long time, and thus the blood flow is depressed, which is one factor causing medical side effects such as deep vein thrombosis, pulmonary embolization, and hematoma.
상기한 압박법의 문제점을 보완한 대표적인 지혈방법으로는 혈관의 천공 부위 내부를 직접 막아서 지혈하는 천공혈관 폐쇄법이 있다. 이 천공혈관 폐쇄법의 시술에는 생분해성 고분자 물질을 이용하여 혈관의 천공 부위를 직접 막을 수 있도록 천공혈관 폐쇄장치가 사용된다.Representative hemostatic method that complements the problems of the compression method is a perforated vascular closure method to directly block the inside of the perforated portion of the blood vessels.

Can be separated from.
본 발명의 일 실시 예에 따르면, 상기 몸체부재(110)는, 외측 표면에 길이방향을 따라 요입된 토출홈(112)을 형성하되, 상기 토출홈(112)이 형성된 구간(D2)은 상기 지혈제(120)가 형성된 구간(D1)보다 길게 형성되어, 외부에서 상기 토출홈(112)을 따라 동맥혈이 빠져 나오는지를 확인하여 상기 몸체부재(110)가 동맥혈관(20)에 삽입되었는지 여부를 판단할 수 있도록 한다.According to one embodiment of the present invention, the body member 110, the discharge groove 112 is formed in the longitudinal direction on the outer surface, the section (D2) in which the discharge groove 112 is formed is the hemostatic agent Is formed longer than the section (D1) 120 is formed, by determining whether the arterial blood exits along the discharge groove 112 from the outside to determine whether the body member 110 is inserted into the arterial vessel 20 To help.
도 5, 도 12, 도 19에 도시한 바와 같이 상기 토출홈(112)은 상기 몸체부재(110)의 외측 표면에 길이방향으로 형성된다. 상기 토출홈(112)은 상기 지혈제(120)가 형성된 구간(D1)보다 길게 형성되는 데, 그 이유는 지혈제(120)가 동맥혈관(20)에 삽입되지 않도록 하기 위함이다. 즉, 상기 몸체부재(110)를 피하조직(10) 및 동맥혈관(20)에 삽입하다가, 상기 토출홈(112)의 하측 단부가 상기 동맥혈관(20)에 삽입되면, 동맥혈이 상기 토출홈(112)으로 유입되고 체외에 위치한 토출홈(112)의 상측 단부를 통해 동맥혈이 빠져 나온다. 이때, 진단 및 치료를 진행하던 의사 또는 간호사는 외부로 빠져 나온 동맥혈을 보고 몸체부재(110)가 동맥혈관(20)에 제대로 삽입되었음을 확인할 수 있고, 동시에 상기 토출홈(112)으로 동맥혈이 빠져 나오지 못하도록 몸체부재(110)를 바깥쪽으로 살짝 잡아당긴다. 이때, 상기 토출홈(112)은 동맥혈관(20) 밖으로 빠져 나오더라도 상기 몸체부재(110)의 하측 단부는 동맥혈관(20)에 삽입된 상태를 유지해야 한다. 따라서, 상기 토출홈(112)은 상기 몸체부재(110)의 하단부에서 소정의 거리(D3)만큼 이격하여 형성될 수 있다.5, 12 and 19, the discharge groove 112 is formed in the longitudinal direction on the outer surface of the body member 110. The discharge groove 112 is formed longer than the section D1 in which the hemostatic agent 120 is formed, for the reason that the hemostatic agent 120 is not inserted into the arterial vessel 20. That is, when the body member 110 is inserted into the subcutaneous tissue 10 and the arterial vessel 20, and the lower end of the discharge groove 112 is inserted into the arterial vessel 20, arterial blood is discharged from the discharge groove ( Arterial blood flows through the upper end of the discharge groove 112 which is introduced into the 112 and located outside the body. At this time, the doctor or nurse in the process of diagnosis and treatment can see the arterial blood leaked to the outside to confirm that the body member 110 is properly inserted into the arterial vessel 20, and at the same time the arterial blood is not drawn out to the discharge groove 112 To prevent the body member 110 is slightly pulled outward. At this time, even if the discharge groove 112 is pulled out of the arterial vessel 20, the lower end of the body member 110 should maintain a state inserted into the arterial vessel 20. Therefore, the discharge groove 112 may be formed to be spaced apart from the lower end of the body member 110 by a predetermined distance (D3).
이하, 도 4 내지 도 7을 참조하여, 상기한 지혈요소가 구비된 의료기구의 사용 예를 설명하면 다음과 같다. Hereinafter, referring to FIGS. 4 to 7, a usage example of the medical apparatus provided with the hemostatic element is as follows.
먼저, 몸체부재(110)를 체내에 삽입하기 전 보호부재(140)를 제거한다. 그리고 나서, 피하조직(10)을 천자하여 몸체부재(110)를 체내에 삽입시킨다. 이 과정에서 상기 몸체부재(110)의 표면에 형성된 지혈제(120)는 상기 몸체부재(110)와 함께 피하조직(10)에 삽입된다. 삽입된 몸체부재(110)가 피하조직(10)을 거쳐, 동맥혈관(20)에 도달하고, 소정의 길이(D3)만큼 더 삽입되면, 몸체부재(110)의 외측 표면에 길이방향으로 요입 형성된 토출홈(112)을 통해 동맥혈이 외부로 빠져 나오게 되고, 외부에서는 몸체부재(110)가 동맥혈관(20)에 도착했음을 확인할 수 있다. 동맥혈이 토출홈(112)으로 빠져 나오는 것을 막기 위해 몸체부재(110)를 바깥방향으로 살짝 잡아당겨 토출홈(112)을 동맥혈관(20)에서 빼내고 그 위치를 고정한다. 이는 토출홈(112)으로 동맥혈이 빠져 나오는지 여부에 따라 확인할 수 있다. 상기와 같이 몸체부재(110)의 위치가 고정되면 의사 또는 간호사는 환자를 진단하거나 치료한다. 그리고, 환자의 진단 및 처치가 완료되면 상기 몸체부재(110)를 피하조직(10) 및 동맥혈관(20)에서 빼낸다. 이때, 상기 지혈제(120)는 몸체부재(110)와 함께 체외로 빠져나오면서, 천자부위를 지혈시키게 된다. First, the protective member 140 is removed before inserting the body member 110 into the body. Then, the subcutaneous tissue 10 is punctured to insert the body member 110 into the body. In this process, the hemostatic agent 120 formed on the surface of the body member 110 is inserted into the subcutaneous tissue 10 together with the body member 110. When the inserted body member 110 reaches the arterial vessel 20 through the subcutaneous tissue 10 and is further inserted by a predetermined length D3, the body member 110 is indented in the longitudinal direction on the outer surface of the body member 110. Arterial blood is discharged to the outside through the discharge groove 112, it can be confirmed that the body member 110 arrived at the arterial vessel 20 from the outside. In order to prevent arterial blood from escaping into the discharge groove 112, the body member 110 is slightly pulled outward to remove the discharge groove 112 from the arterial vessel 20 and fix the position thereof.
