Description

혈관접속을 위한 의료용 연결기구Medical connector for vascular connection
본 발명은 혈관접속을 위한 의료용 연결기구에 관한 것으로서, 상세히는 케이스 내에 1단 패킹부와 2단 패킹이동부가 각각 설치되어, 주사기의 삽입에 따른 상기 2단 패킹이동부의 이동에 의해 1단 패킹부의 절개부를 개방함과 동시에, 상기 2단 패킹이동부 중심의 삽입장공을 통해 주사기의 바늘을 삽입하도록 한 혈관접속을 위한 의료용 연결기구에 관한 것이다.The present invention relates to a medical connection mechanism for vascular connection, in detail, the first stage packing part and the second stage packing moving part are respectively installed in the case, the first stage by the movement of the two-stage packing moving part according to the insertion of the syringe. The present invention relates to a medical connecting device for vascular connection for opening a cutout of a packing part and inserting a needle of a syringe through an insertion hole in the center of the second packing moving part.
본 발명의 배경기술로는 도 5에 도시한 바와 같이, 예컨대 Y자형 튜브(19)에 연결된 헤파린 캡(21)이라고 하는 원통형으로 된 혈관 접속용 연결기구가 있으며, 이러한 상기 헤파린 캡(21)의 재질과 구조를 볼 때 몸체 부분은 플라스틱이고, 상기 몸체 내부의 입구부분에는 주사기 바늘이 삽입되어 드나드는 실리콘 패킹(32)이 설치되어, 상기 실리콘 패킹(32)이 원통형의 몸체 내부의 상단에 위치하게 된다.As the background of the present invention, as shown in Fig. 5, for example, there is a cylindrical connection mechanism for connecting blood vessels called heparin cap 21 connected to the Y-shaped tube 19. In view of the material and structure, the body part is plastic, and the inlet part of the body is provided with a silicone packing 32 into and out of the syringe needle, and the silicon packing 32 is located at the upper end of the cylindrical body. Done.
그런데 이러한 종래 혈관 접속용 기구는 주사기(60)의 바늘(60')로 약액을 주입할 때, 헤파린 캡(21) 내부의 실리콘 패킹(32)이 상기 주사기 바늘(60')에 의해 파쇄되어, 상기 실리콘 패킹(32)의 파쇄된 실리콘 입자의 일부가 주사기(60) 바늘(60') 및 정맥과 연결된 수액 줄을 통해 삽입되어 환자의 혈관에 유입됨으로써 환자에게 위해를 끼칠 수 있는 문제점이 있다. By the way, such a conventional blood vessel connecting mechanism, when injecting the chemical liquid into the needle 60 'of the syringe 60, the silicone packing 32 inside the heparin cap 21 is broken by the syringe needle 60', A portion of the crushed silicon particles of the silicon packing 32 is inserted through the fluid line connected to the syringe 60 and the needle 60 'and enters the blood vessel of the patient, thereby causing a problem for the patient.
이러한 실리콘 패킹(32)에 실리콘 입자가 주사기(60) 바늘(60') 내로 삽입하지 않도록 상기 바늘(60')이 통과하는 바늘, 구멍을 형성할 수 있으나, 혈관 내에 주사기(60)로 약액을 주입할 때에는 공기가 들어가지 않도록 진공상태를 유지해야 하기 때문에 일단 실리콘 패킹(32)으로 헤파린 캡(21)의 내부를 폐쇄하는 것이다. The silicon packing 32 may form a needle, a hole through which the needle 60 'passes, so that the silicon particles do not insert into the needle 60' of the syringe 60, but the chemical liquid is injected into the blood vessel by the syringe 60. When injecting, since the vacuum must be maintained so that no air enters, the inside of the heparin cap 21 is closed with the silicon packing 32.
따라서 헤파린 캡(21)과 같은 의료기구를 사용할 때, 상기 헤파린 캡(21) 내부의 진공상태를 유지하면서도 주사기(60) 바늘(60') 내에 이물질이 삽입되지 않도록 하는 것이 중요하다. Therefore, when using a medical device such as the heparin cap 21, it is important to prevent foreign substances from being inserted into the needle 60 'of the syringe 60 while maintaining the vacuum inside the heparin cap 21.
