摘　　要：研制了一种新型的医用点滴自控报警装置,该装置利用光电检测方式工作。通过设定液体的位置可以改变该液位的折射率,改变光线的出射角,从而引起光电二极管接收光强的变化,检测电路侦测到该变化后接通本地及遥控装置进行报警。经实验证明该装置工作可靠,灵敏度高,可应用于医疗及工业液位中。A new type of automatic droping alarm apparatus for medical application is designed to work by using photoelectric detect method. We can change the refractive index by setting the liquid level. The refractive index which means different refractive angle and the change of light intensity received by the diode. This alteration triggers the local and remote beeper through the alarm circuit. The apparatus has been proved reliable and highly sensitive and can be used in medical instruments and industrial control.
