Wearable medical guardianship system based on ZigBee

The medical guardianship system based on ZigBee wearable sensors is designed to reduce the size of medical equipments and realize wireless medical guardianship, which is able to expand patient's activity area, relief work intensity of paramedics, and lower medical expense. The system has two-layer structure, including inpatient area and guardianship center, which collects patient's temperature, pulse, and other physiological parameters by wearable sensors. The parameters were processed, and then sent to the wireless communication module, transmitted to the guardianship center by ZigBee wireless network finally. Physiological parameters of patients were obtained through system experiments, and compared with the traditional measurement data. The results show that the system is stable and reliable, which realizes the acquisition, wireless transmission, storage and display of physiological parameters, and meets the design requirements.
