Design of ECG Monitoring Analyzer Based on MicrocontrollerCC2530 / 中国医疗器械杂志

<p><b>OBJECTIVE</b>A remote wireless electrocardiogram (ECG) monitoring system is designed by using the CC2530 micro-controller as the device core.</p><p><b>METHODS</b>Acquisition, conversion and data processing for ECG signals are realized on CC2530 micro-controllers. And the ECG data is transmitted to the coordinator by using ZigBee. It realizes the real-time monitoring of ECG signals and heart rate variability (HRV) data.</p><p><b>RESULTS</b>The test results show that the maximum error of the designed ECG monitoring analyzer is 3 beats per minute and the average error is 1.6 beats per minute, which can meet the requirement of pharmaceutical industry standards of the People's Republic of China.</p><p><b>CONCLUSIONS</b>The ECG monitoring analyzer has good portability, high measurement precision and good practical application values.</p>

Design and implementation of infusion monitoring system based on improved capacitance detection method / 医疗卫生装备

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.
