Design of wearable multi-parameter monitor / 医疗卫生装备

ABSTRACT

Object To develop a wearable multi-parameter monitor to facilitate cardiac monitoring of the aged.Methods The monitor had MSP430F5529 micro controller as the core unit, which realized physiological signals acquisition, transmission and storage with ADS1292R chip 2-channel analog front-end to acquire ECG and respiratory signals, ADXL345 sensor to collect postural information, and Bluetooth 4.0 module to send the acquired data to the intelligent mobile terminal and store them in TF card.Results The developed monitor had the continuous working time being 24 hrs, and provided auxiliary diagnosis by monitoring ECG, respiration and posture parameters.Conclusion The monitor behaves well in small size and high wearability, and gains prospects in ECG monitoring in the field of mobile medicine.
