| Abstract: | We have fabricated an automatic alarm device for medical transfusion.This device is mainly composed of pulse-modulated light source,plastic optical fiber,photo diode,and alarm circuit.The alarm signal is immune from the unwanted light interference due to the application of pulse modulation.The use of plastic optical fiber allows us to carry out the remote and non-contact monitoring to the medical transfusion.In addition,this device is simple,practical,inexpensive,and easy to install.The feasibility of this automatic alarm device has been demonstrated by experiment. |
