Abstract
Official abstract text for this publication.
An extracorporeal blood chamber for an optical blood monitoring system includes an opaque chamber body in order to prevent inaccuracies when measuring oxygen saturation levels due to light ducting, which can occur at low oxygen saturation levels and low hematocrit levels. In one embodiment, the blood chamber need not include a moat as is present in conventional blood chambers.
First claim
Opening claim text (preview).
What is claimed is: 1. A blood chamber connected to an extracorporeal tube for optically monitoring blood flowing through the extracorporeal tube, the chamber comprising: a chamber body forming an internal blood flow cavity which provides flow path for the flowing blood and includes a flat viewing area for optical monitoring of the blood using a photoemitter and a photodetector; a portion of the chamber body outside the flat viewing area tinted blue and opaque to red light and…
