Research on the design of household coagulation testing product service system

In this study, the product service system was introduced to study and design the postoperative health management of patients with coronary heart disease, aiming at solving the problems such as difficult medication guidance and high reexamination time cost for patients with coronary heart disease. The user journey map, which focuses on user experience, was used to identify the requirements and pain points of postoperative health management of patients with coronary heart disease. Combined with Kano model, the functions transformed from requirements and pain points were classified and prioritized to guide the design of product service system. Through the research, the framework of product service system is established, and the household coagulation testing product service system is visually displayed through the service blueprint. The design of household coagulation tester, interactive interface of mobile and computer software is produced, so as to improve the efficiency and effectiveness of health management for patients with coronary heart disease and realize a one-stop service platform integrating medical diagnosis, medication guidance and health management. The findings of this study propose a new noninfectious chronic disease (NCD) management mode taking coronary heart disease health management as an example, and provide a reference for the research of NCDs management system in China.
