Abstract:
Objective To design a high-performance, reliable and practical wireless infusion monitoring system to realize automated infusion monitoring.Methods The system was composed of an infusion monitor,an intelligent gateway and a host computer, which used AD7746 chip to monitor the electric capacity, I2C serial bus for capacity-related data readback, CC2530 SCM for difference calculation and infusion state determination, and ZigBee technology to execute wireless data transmission at real time.Results The system carried out multi-node monitoring on volume and velocity at real time,and the acquired data were accurate and reliable.Conclusion The system gains advantages over the traditional ways in practicability and reliability when used for infusion monitoring.
