The PHRsync Smart Home Healthcare Monitoring System connects patients, healthcare professionals, and family members through an integrated platform consisting of a mobile app, a management portal, and a home gateway device. It supports real-time monitoring via smart devices such as the ASTRI Chest Patch, which tracks ECG, respiration rate, skin temperature, and detects falls. Patients can record health data, receive reminders, and report discomfort through the app. Family members can monitor patient status, while healthcare professionals access real-time data, adjust treatment plans, and provide remote guidance. The Home Gateway device is preloaded with the PHRsync app and is ideal for patients unfamiliar with smartphones, offering a simplified interface and built-in camera for remote check-ins. The system supports daily health management, remote medical consultations, emergency alerts for abnormal readings or disconnection, and strengthens collaboration between caregivers and families. It aligns with Hong Kong’s primary healthcare goals—focusing on prevention, early detection, data sharing, and family involvement. Future developments include AI-powered health risk prediction and expanded connectivity with other devices (e.g., call bells, motion sensors), enabling a more comprehensive and proactive approach to home-based chronic disease management and elderly care.
