摘　　要：利用差分吸收光谱法与输液监测系统的结合,研究水对光的吸收变化.事先将引起输液监测系统警报器响应的电压、电流设置在一定的范围内.将光分为2路,一路经过含有水的输液管;另一路经过未含有水的空输液管.利用光电转换器将经过输液管的光信号转换为电信号,传输到输液监测器中引发警报器响应.Using the combination of differential absorption spectroscopy and the infusion monitoring system to study the changes in water absorption of light,the voltage and current that cause the alarm of the infusion monitoring system to be sounded are set within a certain range in advance.Then the light is divided into two channels,one way through the infusion tube that contains water,the other way through the empty infusion tube that does not contain water.The photoelectric converter is used to convert the optical signal into an electrical signal,which is transmitted to the infusion monitor to trigger.

关 键 词：差分吸收光谱法 输液监测系统 光电转换器 水的吸收谱
