為了實時檢測血氧量,能使缺氧特別敏感的腦組織或心臟類疾病患者得到及時治療,采用近紅外雙波長透射式光電脈搏血氧測定法,以H橋電路對發射光源進行控制及通用運算放大器搭建濾波電路。運用參數理論計算和計算機仿真結果相對比的方法,通過Mu ltisim軟件對所設計電路進行仿真,仿真結果與理論參數計算相吻合,證明了電路參數設計的可行性,為血氧儀的實物制作提供參考。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 physical blood-oxygen monitor.
