基于动态光谱法的血红蛋白检测系统

　　贫血严重威胁着人类健康。血红蛋白含量是评价人群贫血患者率和铁营养状况的重要指标，在临床上诊断中有着很广的应用价值。本设计根据动态光谱理论，借助ADSP-BF506F强大的数据处理能力，采用调制解调的方法获取多个波长的光电脉搏波。对获取的光电脉搏波滤波，利用频域分析的方法提取脉搏波基波分量，实现血红蛋白的检测。系统软硬件的设计基本完成，为血红蛋白无创检测进入临床打下了良好的基础。此外，系统可以利用到血糖的无创检测上。

　　Noninvasive haemoglobin measuring system based on Dynamic Spectrum Theory

　　Anemia significantly threatens peoples’ health. The content of haemoglobin is an important index which evaluates the rate of anemia patients and the iron status. Themeasurement of haemoglobin shows a great value in clinical diagnoses. Based on Dynamic Spectrum Theory, this design uses ADSP-BF506F as the core microcontroller which has the powerful data processing ability.The design gets the photoelectric pulse waves of different wavelengths by the method of modulation and demodulation. Applying the frequency domain analysis calculates the fundamental component of the pulse wave to realize the measurement of haemoglobin. The design of the system software and hardware was basically completed, which lays a good foundation for the noninvasive measurement of haemoglobin entering the clinical application. More importantly, the system can be applied to noninvasive glucose detection.
