摘　　要：本文介绍了专用于贫血类型诊断的红细胞寿命测定仪器的研制。测定仪由气路、电子电路、零气制备三大部分组成,测定仪基于非色散红外光谱原理,通过零气制备、特殊进样处理、微弱信号线性保真等技术创新,实现了非色散红外光谱技术准确测定小量、低浓度CO气体的目的。测定仪测量0.55ppm、0.95ppm、1.20ppm标准CO气体,平均误差分别为0.036、0.038、0.063,精密度分别为8.98%、4.68%、5.10%,符合红细胞寿命测定的临床需要。A new erythrocyte life span measuring instrument designed for anemia diagnosis was introduced.The instrument include three systems：gas circuit,electronic circuit and zero gas preparation.With the new technique such as zero gas preparation,special sample injection dispose and weak signal linear fidelity,etc,this instrument based on NDIR can achieve the measurement of a small quantity and low concentration CO.The 0.55 ppm,0.95 ppm and 1.20 ppm normal CO were measured by the instrument,it＇s found that the average errors are 0.036 ppm,0.038 ppm and 0.063 ppm,and precisions are 8.98%,4.68% and 5.10%,respectively.These results fulfilled the clinical need in erythrocyte life span measure.
