Blood fluid characteristics analysis instrument |
摘要 |
An apparatus for enhancing the analysis of light reflected from a blood exposed reagent is described. Light from sources, such as LED's, is used to detect the levels of glucose and fructosamine in the blood exposed reagent. A special optical arrangement is used ot obtain optical signals indicative of the optically sensitive chemicals in the reagent. The optical beams from respective LED's are directed at a common surface of an optical element used to redirect the light onto the reagent and reflect portions onto a reference detector. A main detector is strategically located adjacent a surface of the optical element to detect reflections from the reagent. A control circuit is described with which the light from the LED light sources can be held at substantially constant levels despite factors tending to cause light level changes.
