From the perspective of virtual value, focusing on the valueadded big data of intelligent medical maintenance, the big data platform of intelligent medical maintenance is established, and an integrated 5 I’s model featuring intelligent smart medical maintenance is built based on the platform. The 5 I’s model is an integrated pension model of the intelligent medical maintenance, which relies on intelligent devices, takes information as a carrier, uses integration as a solution, and aims at the individualized and immediate services. By using big data, the model enables the service demander (the elderly), the service supplier (community, hospital and nursing home) and the service responsibility subject (government and the guardians of elderly) to have access to the timely and complete big data of the intelligent medical maintenance. Based on data analysis and data mining, the 5 I’s model can also provide the elderly with quick and accurate integrated services of the intelligent medical maintenance and build a perfect service system of completeperiod supervision. The study also makes a detailed analysis of the guarantee mechanism of 5 I’s model to realize industrializing integrated services of the intelligent medical maintenance and meet the huge pension demands in China.
