摘要
一氧化氮(NO)是生物体内重要的信使分子和效应分子,同时临床上根据人体呼出的NO浓度可诊断哮喘及气道嗜酸性粒细胞炎症、判断哮喘患者对于激素治疗的敏感度.鉴于此,设计基于吸收光谱的气体检测系统,测量人体呼出的NO浓度.实验结果表明:该文系统的测量精度小于1%,满足设计要求.该文系统可推广应用于其他气体的快速检测.
Nitric oxide(NO) is an important messenger molecule and effector molecule in vivo. At the same time, the concentration of NO in human exhaled breath can be used to diagnose asthma and airway eosinophilic inflammation and to judge the sensitivity of asthma patients to hormone therapy. In view of this, a gas detection system based on absorption spectrum was designed to measure the concentration of NO exhaled by human body. The experimental results showed that the detection accuracy of this system was less than 1%, which met the design requirements. This system could be applied to the rapid detection of other gases.
