Continua ECG Device Solutions: An X73-PHD Bluetooth Adaptor and An x73-PHD ZigBee Adaptor

摘要

With the increase of aging population and the threat of cardiovascular disease, ECG monitoring system becomes important healthcare equipment. However, current ECG monitoring systems are private communication systems. There is a necessary need for intercommunication and exchange measurement data among the various ECG devices and application hosting devices within a single system. The study proposes two designs: one is for the x73-PHD Bluetooth adaptor and the other is for the x73-PHD ZigBee adaptor. Both x73-PHD adaptors act as agent of ECG device. The x73-PHD adaptor collects the measured data and transmits them compliant with the international standard 11073 data format via a Bluetooth Health Device Profile (HDP) or ZigBee Health Care Profile (HCP) interface. The design for the x73-PHD Bluetooth adaptor proposed in this paper is based on the MSP430F5529 and Stollmann chipsets as well as the x73-PHD ZigBee adaptor is based on the Freescale ZigBee chipset. Each of the adaptors adopts the ISO/IEEE 11073 standards, which functions as a bridge between the application hosting device and the ECG device. The x73-PHD adaptor converts vital sign data from the connecting ECG device, and then transmits these data (waveform or heart rate) to the application hosting device in compliance with ISO/IEEE 11073 personal health device data format and protocol standards via the Bluetooth HDP or ZigBee HCP interface. Based on the testing results, users can transmit ECG waveform or heart rate data to any application host device certified by Continua Health Alliance over the Bluetooth HDP or ZigBee HCP interface successfully.
