Abstract :
Based on the azide methemoglobin method, a portable hemoglobin concentration determinator has been developed, utilizing the disposable microcuvette containing reagent, which could be used for performing the quick online test of undiluted and unhemolyzed whole blood within 30 to 60 seconds. In this paper, a detailed description has been made on measuring principle, measuring mechanism, controlling system and derivation of concentration calculating formula. As the clinical trials indicates that the pertinence of the measurement result and the accuracy can reach as high as 0.9836 and 96.32% respectively compared to cyan-methemoglobin method. The instrument can be widely applied in moveable blood collecting - and - supplying institutions, assessing athletic performance and family health care etc.
