Abstract
Description
도 2는 본 발명의 다른 실시예에 따른 기관 내관의 개략 구성단면도이다.
300,400: 단방향 날개판 410: 공기유입로
Claims (5)
- 일단은 환자의 기관 내에 삽입 배치하고, 타단은 기관 외부로 노출되는 중공의 원통 형상을 가지는 관형 본체와;
상기 관형 본체의 일단 외측면에 구비하며, 기관 외부에서 공급되는 공기를 통해 팽창하는 커프; 및
상기 커프의 외측 둘레를 감싸도록 원형링 구조를 가지며, 내측 단부는 커프의 외측면에 고정되게 결합하는 연질의 단방향 날개판;을 구비하며,
상기 단방향 날개판은, 관형 본체를 통해 기관 내부에서 외부로의 흡기시에 발생하는 압력을 통해 밀림되면서 외측 단부가 기관 내벽에 밀착되어, 커프와 기관 내벽 사이를 밀폐상태로 유지하고,
상기 단방향 날개판은 관형 본체의 길이방향 일단에서 길이방향 타단방향으로 갈수록 하향 경사지게 형성되어, 기관 내부에서 외부로의 흡기시에 발생하는 압력을 통해 기관 외부 방향으로 밀림되더라도 단방향 날개판의 외측 단부가 펼침되는 방향으로 이동하면서 기관 내벽에 안정적인 밀착상태를 유지하며,
상기 단방향 날개판은 관형 본체에 접하는 내측 단부에서 관형 본체로부터 멀어지는 외측 단부로 갈수록 두께가 얇아지도록 형성되어, 기관 내부에서 외부로의 흡기시에 발생하는 압력을 통해 기관 외부 방향으로 밀림 이동시 단방향 날개판의 접힘을 방지할 수 있는 강도를 제공함과 더불어 기관 내벽에 밀착된 상태에서 필요 이상의 높은 압력이 기관 내벽에 가해지지 않도록 단방향 날개판의 밀림 이동되는 범위를 한정하는 기관 내관. - 삭제
- 삭제
- 청구항 1에 있어서,
상기 단방향 날개판의 내측에는 방사형의 공기유입로가 형성되며,
상기 공기유입로는 커프의 내부와 연결되는 기관 내관. - 청구항 1에 있어서,
상기 단방향 날개판의 외측 단부에는 평판 형태의 보조 날개판이 연장 형성된 기관 내관.
