便携式HGB测量系统设计

Design of Portable HGB Measurement System

针对目前单波长法HGB(血红蛋白)测量仪需要测量空白溶液进行对比校正的缺陷,提出了一种便携式双波长HGB测量系统。系统主要包括恒定光源、比色池、光接收器、ARM控制与数据处理单元、LCD显示等模块。经过实际测试表明,该系统性能稳定,精度高,比单波长法更加高效,可以较好的满足临床医学的需要,具有一定的实用性和推广价值。

This paper proposes a portable dual-wavelength HGB measurement system to avoid the defect that the single-wavelength HGB （Hemoglobin） admeasuring apparatus needs to measure the blank solution for comparison and correction,The system consists of constant light sources,residual,core controller based on ARM,data processing unit,LCD part and so on. Compared with the methods of single-wavelength measurement,the system is proved to be high-efficiency and can work at a high speed,and well meet the need of clinical medicine,The technology and methods adopted in the system are practical and can be extensively used.
