Title: 혈액 모니터 장치의 개선된 보정 방법
IPC: A61B5/00
Filed: 2000-04-20
Abstract: 본 발명은 혈액 모니터 장치의 개선된 보정 방법에 관한 것이다.  생체내 측정에 대한 한정된 광학 경로길이의 부재는 분석물 농도의 비침입성 측정에 문제를 야기한다.  이러한 문제들은 여러 파장에서의 측정값을 조합하고 일반적인 신장 기능이 전체 혈액내 물의 농도가 정밀하게 조절되도록 한다는 사실을 사용함으로써 감소될 수 있다.  그러므로, 동맥혈내 물 농도는 이러한 측정에 대한 내부 표준으로서 사용될 수 있다.  다음으로, 측정값은 조사 방사선에 의해 이동된 경로길이 및 조사 방사선이 전파한 부피의 산란 특성에 대한 농도의 의존성을 제거하기 위해 얻어진다.  이러한 방법을 사용함으로써, 동맥혈내 흡수 성분의 측정값에 대한 개선된 보정이 가능하고, 이에 따라 동맥혈내 헤모글로빈 및 글루코오스와 같은 성분의 절대 농도 측정값을 제공할 수 있다.
