Nurses always estimate the spending time to replace or remove the drip bag when patients taking drip infusion. However, there still have risks that the air seep into the artery or blocked up in the artery if patients fell asleep or nurses are too busy. Therefore, this design aims to put a sensor at the drip bag or the drip bottle. It can determine if the liquid is soon to be empty through the light sensing. When it’s almost run out of the liquid, the sensor will send signal to the nurse to notice them.
