Description

액체 공급 시스템에서 공기를 검출하기 위한 장치 및 방법
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
도면의 제1도는 본 발명에 따라 구성된 주입 장치의 선도, 제2도는 버블 검출기의 초음파 송신기와 수신기 사이의 주입관 내에서 공기 버블의 진행을 상세히 도시하는 선도, 제3도는 주입펌프가 공기 버블을 진행시킴에 따라 그것이 어떻게 변하는가를 보여주는 버블 검출기 출력을 도시한 도면.

Claims (11)

  1. 액체 분리 소스로부터 주입관을 통하여 액체를 환자에게 공급하기 위한 주입 펌프 수단, 주입관에 공기 버블의 존재를 검출하기 위한 버블 검출기 수단, 및 공기 버블의 크기가 수용할 수 없는 것인가를 결정하기 위한 버블 검출기 수단에 응답하는 제어수단을 포함하고, 이 제어수단은 공기 버블이 검출될 동안 그것이 수용할 수 없는 크기를 나타내는 거리를 진행하는 가를 결정하는 것을 특징으로하는 주입 장치.
  2. 제1항에 있어서, 상기 제어 수단이 공기 버블이 검출된 동안 진행한 거리를 결정하기 위해 상기 주입 펌프의 동작을 감시하는 것을 특징으로 하는 주입장치.
  3. 제1항에 있어서, 상기 주입 펌프가 선형 연동 주입 펌프이고, 상기 제어수단이 공기 버블이 진행하는 거리의 지시로서 주입 펌프의 스텝을 계수하는 것을 특징으로 하는 주입 장치.
  4. 제1항에 있어서, 상기 제어수단이 마이크로프로세서 회로를 포함하는 것을 특징으로 하는 주입 장치.
  5. 제1항에 있어서, 상기 제어수단이 공기 버블의 크기가 수용할 수 없다면 상기 주입 펌프를 정지시키는 것을 특징으로 하는 주입 장치.
  6. 제1항에 있어서, 상기 제어 수단이 공기 버블의 크기가 수용할수 없다면 경보를 발생시키는 것을 특징으로 하는 주입 장치.
  7. 제1항에 있어서, 상기 버블 검출기 수단이 초음파 버블 검출기를 포함하는 것을 특징으로 하는 주입 장치.
  8. 제7항에 있어서, 상기 초음파 버블 검출기가 고정 길이 버블 검출기인 것을 특징으로 하는 주입 장치.
  9. 액체를 환자체내에 공급할때 통과하는 주입관에 수용할 수 없는 크기의 공기 버블을 검출하는 방법에 있어서, 주입관을 통해 액체를 공급하기 위한 주입 펌프 및 주입관내의 공기 버블의 존재를 검출하기 위해 설치된 버블 검출기를 갖는 주입 장치를 설치하는 단계, 공기 버블이 검출될 동안 그것이 수용할 수 없는 크기를 지시하는 거리를 진행하는 가를 결정하는 단계를 포함하는 것을 특징으로 하는 방법.
  10. 제9항에 있어서, 수요할수 없는 크기를 지시하는 거리를 공기버블이 진행하는 가를 결정하는 상기 단계가 주입 펌프 동작을 감시하는 것을 포함하는 것을 특징으로 하는 방법.
  11. 제9항에 있어서, 설치하는 상기 단계가 선형 연동 주입 펌프를 갖는 주입 장치를 설치하는 것을 포함하고, 공기 버블이 수용할수 없는 크기를 지시하는 거리를 진행하는 가를 결정하는 상기 단계가 주입펌프의 스텝을 계수하는 것을 특징으로 하는 방법.
