The present paper is to design an infusion alarm system of one leader with multi-followers , which uses photo-electricity to detect liquid level change in the infusion tube, to determine the infusion is complete or not through discriminating the liquid surface changes of electrical signal. The timely alarm prompt of transfusion completion transfers the alarm signal to the alarm terminal via the Bluetooth wireless by using the SCM, to achieve the dual alarm which from the machine-infusion test terminal and the host machine-alarm terminal. The use of master-slave machine’s Bluetooth can make the whole infusion alarm system to achieve the centralized management which from one host machine-alarm terminal to many slave machines-infusion test terminal over the same time .Bluetooth wireless transmission can make the slave machine-infusion test side to move arbitrarily within the range that host Bluetooth effective signal coverage, so it can solve infusion management problems very well, reduce paramedics’ pressure and ease the lack of paramedic.
