| The trend of aging in our country makes the related older industries concerned, However, the elderly household medical products can not meet the needs of the elderly in the home environment. Therefore, how to transform home medical products designed to make it more suitable for elderly become an urgent issue in the field of Elderly product areas.In recent years, the development of the Internet of things(IOT) technology has a tremendous impact on the elderly household medical products industry. And these products did not form a mature product system, but also ignored the interests of the various sectors of the industry, making the development of the industry into the bottleneck period.Therefore, thesis the to the elderly household medical products for the study, based on existing theories and case of IOT, build a service model in the elderly household medical product systems, and based on this service model, we designed a product system model which includes person-Product-environmental, and complete product design practice on the basis of this system.Firstly, through a large number of literature and case analysis, the paper analyzes the characteristics of the elderly medical products and their service mode. On this basis, the author decompose the medical product life cycle, and get the interest groups of the service mode. Then through the interview with the elderly users to summarize, in order to build the user role models. After completing the above analysis, Building service model in product system which is the human factor of product system.Secondly, after planning of the system position, the Usage scenarios and the overall goal, combined with service model has been constructed, mixing the product factors and environmental factors, then design the system of elderly household medical products, and analyze the system in-depth explanation. At last, design a specific product design and APP design to complete design practice.
