제2도는 제1도와 유사하나 수축위치의 바늘 방호물을 보여준다.
제3도는 제2도의 라인(3-3)을 따라 절단한 주사기 원통을 보여 주는 단편적인 단면도.

Claims (7)

  1. 다른 밀폐단부에 부착하고 세로축의 동축방향으로 확장하는 피하 바늘이 달린 주사기 원통과, 이 피하바늘을 위한 것으로서 주사기 원통에 활주할 수 있도록 설치 하여 회전위치와 확장위치 사이의 주사기 원통을 축운동시키는 수축 및 확장 방호물과, 이 주사기 원통 바늘방호물 사이에 설치하고 바늘방호물 내면상의 고정돌출부를 포함하고 주사기 원통 외면에 형성된 미끄럼홈(guideway)속에 수용되는 고정수단을 포함하며 한편 이 미끄럼 홈의 각축 단부에는 고정부가 있고 고정수단이 주사기 원통의 원주위로 확장하는 미끄럼홈의 확장범위에 속해있고, 또한 바늘방호물을 세로축 주위의 정해진 곳까지 회전시켜 풀고 다시 이 바늘방호물은 미끄럼홈 내에서 움직이는 돌출부의 인도하에서 주사기 원통축 방향으로 이동시키며 이 바늘방호물이 선별된 하나의 고정수단과 고정돌출부를 맞물려서 선별된 하나의 수축 및 확장위치에 고정할 수 있는 것을 특징으로 하는 피하주사기.
  2. 제1항에 있어서, 이 주사기 원통이 견고하고 원형의 단면으로 되어있으며, 바늘방호물은 유연한 탄원형 단면으로 되고, 이 타원형 단면의 보조축은 고정 돌출부를 통해 확장하고, 한편 주사기 원통의 주위를 방사상으로 움직이는 고정 돌출부는 바늘 방호물을 주축방향으로 압축시켜 주사기 원통과 맞물린 고정부를 풀수 있는 것을 특징으로 하는 피하주사기.
  3. 제1항에 있어서, 주사기 원통과 바늘방호물 사이에 위치하고 언제나 움직일 수 있어서 바늘방호물을 확장위치로 이동시키는 압축 스프링을 포함하는 피하주사기.
  4. 제1항에 있어서, 바늘에서 간격을 두고 부착된 말단-캡을 포함하는 피하주사기.
  5. 제1항에 있어서, 개방된 바늘방호물 말단부를 가로질러 확장하고 또한 바늘방호물 수축시에 피하바늘에 의해 파열될 수 있는 파열격막을 포함하는 피하주사기.
  6. 제1항에 있어서, 미끄럼홈이 주사기 원통축방향으로 확장하는 직선 중심부와 또한 각 단부에서 이 주사기 원통의 원주상으로 확장하는 원형부를 포함하고 각 원형부는 고정수단을 갖추고 있어서 고정돌출부와 함께 공동작용하는 것을 특징으로 하는 피하주사기.
  7. 제1항에 있어서, 주사기 원통을 폴리메타크릴레이트 재료로 것을 특징으로 하는 피하주사기.
