摘要：

为了实时检测血氧量,能使缺氧特别敏感的脑组织或心脏类疾病患者得到及时治疗,采用近红外双波长透射式光电脉搏血氧测定法,以H桥电路对发射光源进行控制及通用运算放大器搭建滤波电路。运用参数理论计算和计算机仿真结果相对比的方法,通过Multisim软件对所设计电路进行仿真,仿真结果与理论参数计算相吻合,证明了电路参数设计的可行性,为血氧仪的实物制作提供参考。

Abstract:

For real-time detection of oxygen saturation for timely treatment of the brain or heart,which are very sensitive to oxygen inadequacy,the near-infrared wavelengths double photoelectric pulse oximeter transmission method is adopted.The illuminant is controlled with the H bridge circuit and the filter circuit is built with general op-amps.Parameters by theoretical calculation is compared with the computer simulation results in Multisim and satisfactory results are obtained.It is shown that the design of the circuit parameters is feasible and can be a help in making the phy
sical blood-oxygen monitor.

Key words: Multisim simulation;oxygen saturation;double wavelength projection measurement;photoelectric diode;filter parameter design;H bridge driving circuit
