摘要
血氧含量的监测对人体生理健康具有重要的意义,为了实现无创监测人体组织血氧含量,利用还原血红蛋白和氧合血红蛋白对近红外光吸收光谱的差异性,运用朗伯-比尔定律,设计了一套便携式无创监测组织血氧含量的系统,通过对系统进行标定,建立了血氧含量与近红外光透射光强的数学模型。实验验证绝对误差范围在±2%,验证了设计的合理性和实用性。
Blood oxygen content is an important parameter reflecting the physiological condition of the hu- man biological tissue, which has great significance to diagnosis and clinical nursing, etc. The develop- ment of NIRS makes noninvasively monitor tissue oxygen content possible. A portable non-invasive moni- toring of organization blood oxygen content system is designed based on Lambert-beer law and the near-in- frared absorption spectrum difference between reduced hemoglobin and oxy-hemoglobin. The proposed system is calibrated to establish the mathematical model of the blood oxygen content and the near-infrared light intensity. The experimental results show that the absolute error is within the range of ± 2% , which confirms the rationality and practicality of the design.
