Design and Implementation of a Hierarchical Diagnosis-Assisted Tool on HarmonyOS

This study describes the design and development of an intelligent medical app that combines the DeepSeek-R1 model with HarmonyOS technology. The app offers key features like smart symptom search, online consultation, and diagnostic assistance. After introducing the core technologies, the system’s overall architecture and module functions were outlined, and the main components were implemented through coding. The goal of this system is to improve healthcare delivery, make smart medical tools more accessible, and support the digital transformation of the healthcare industry.
