Abstract

본 발명은 주사기 앞부분에 일반적으로 장착된 공동형의 바늘; 얇은 디스크 플런저와 일체적으로 형성된 화살머리 형태의 결합부재; 주사용되를 위해 플린저가 주사기내에 미끄럼 가능하게 장착될 수 있도록 플린저상에 삽입된 환형링; 공동형 바늘의 후방 바늘부에 패인, 바늘의 바늘축에 경사진 길이방향의 사선축을 가진 통상 원추형으로 형성된 사선 구멍과 연결될 수 있는 플린저상에 형성된 결합부재로 구성되고, 이로써 플런저와 이와 결합된 바늘이 주사기내로 후퇴했을 때 바늘이 기울게 되어 후퇴된 바늘이 더 이상 밖으로 돌출되지 않도록 방지되는, 비용절감을 위한 최소화된 얇은 디스크 플린저를 가진 안전 주사기에 관한 것이다.

Description

Claims (1)

  1. 내부에 의약액을 충전시키기 위한 공동의 구멍부를 가진 주사기 실린더, 주사기 수단의 앞부분에 형성되고 주사기 수단에 중심구멍을 형성시키는 슬리브무, 및 주사기 수단의 중앙부분에 길이방향으로 한정된 주사기 축으로 구성된 주사기 수단; 원추형 바닥, 원추형 바닥으로부터 앞으로 갈수록 좁아지는 원추형 정점 및 바늘장치의 중심부에 길이방향으로 한정되고, 주사를 위해 바늘장치를 상기 주사기 수단에 정착시켰을 때 상기 주사기 수단의 주사기 축에 배열된 바늘축으로부터 예각으로 벗어나 사선축으로 배열되는 길이방향의 사선축으로 구성된 바늘수단의 후방마늘부에 형성된 통상적으로 원추형인 사선구멍을 가진 상기 주사기 수단의 상기 슬리브부에 보유된 몸통부에 고정된 공동의 바늘부를 포함하는 바늘장치; 주사기 실린더내에 의약액을 충전시켜 상기 바늘장치를 통해 주사하기 위해 상기 실린더내에 미끄럼 가능하게 장착된 플런저 수단; 및 사선구멍내에 작동가능할 정도로 강하게 삽입되어 바늘장치를 화살머리부분과 결합시키므로써 주사완료후 상기 바늘장치의 후방바늘부의 탄성복귀 예너지를 저장시키는, 결합부재의 앞 끝에 형성된 화살머리 부분을 가진 상기 플런저상에 형성된 화살머리 부분을 가진 상기 플런저상에 형성된 결합부재로 구성되고, 상기 플런저에 결합된 바늘장치와 플런저가 상기 주사기 실린더내로 후퇴시, 상기 바늘장치는 자동적으로 원상복귀되고 비스듬하게 기울어지므로써 상기 주사기 수단의 바깥으로 상기 바늘장치가 재-돌출되는 것이 방지되는 안전 주사기에 있어서, 상기 플런저는 그 앞부분에 일체적으로 형성되어 있으면서 목부분에 의해 상기 플런저에 일체적으로 결합된 상기 화살 머리 부분을 가진 얇은 디스크 플런저, 및 상기 플린저가 상기 주사기 실린더내에 미끄럼 가능하게 장착될 수 있도록 상기 얇은 디스크 플런저의 둘레에 형성된 환형 홈내에 삽입된 환형 펙킹 링을 포함하고, 상기 화살머리 부분의 후방 말단부 둘레에는 톱니가 형성되어 있으며, 상기 플런저는 이와 일체적으로 연결되어 있으면서 이로부터 후방으로돌출되어 있는 플런저 손잡이와 일체적으로 부착된 플런저 봉을 가지며; 상기 바늘장치내의 상기 사선구멍은 후방 바늘 부분 주변에 형성되어 있으면서 상기 사선구멍의 원추형 바닥으로부터 뒤로 갈수록 방사상으로 좁아지는 톱니 홈을 가지고, 이로써 상기 플런저 수단의 상기 화살머리 부분상의 사이 톱니와 상기 바늘장치중 상기 톱니 홈이 견고하게 결합되므로써 주사를 완료한후 상기 플런저 수단과 상기 바늘장치가 안정하게 결합되는 것을 특징으로 하는 안전 주사기.
