Abstract:
Objective To develop an electronic infusion alarm system with low cost and high safety and reliability.Methods The system was composed of modules of sensor, control, alarm and DC power supply. The integrated operational amplifier was used to amplify the voltage signals from the cantilever sensor, and NE555 timer controlled the system give out alarm when 10% liquid remained in the bottle.Results The system could alarm when 10% liquid remained in the bottle, and three gears were designed for the common infusion bottles in the market.Conclusion The system is easy to operate and maintain, and thus can be popularized in all hospitals and clinics.
