The work aims to explore innovative design methods of the diagnosis and treatment bed to improve the satisfaction of doctors and patients in the use of the diagnosis and treatment bed, and improve the reliability and practicality of the diagnosis and treatment bed .An application model of QFD and AHP was constructed. Firstly, core user demands were obtained through user interviews, and QFD was used to transform core user demands into design features. Then according to the conclusions drawn by QFD, a hierarchical model of the design characteristics of the diagnosis and treatment bed was established in combination with AHP and with a judgment matrix for each level. The design characteristics to be prioritized were obtained through weight calculation. After calculating the design characteristics that need to be prioritized, namely the replacement structure of the pad cloth, the waste storage structure, the overall external structure, the material and the process, the innovative design of the diagnosis and treatment bed was carried out with these four entry points.The application model integrated with QFD and AHP can not only meet the demands of users, but also systematically and accurately judge design indicators, complete program decisions, effectively develop products, and improve design efficiency. This application model can provide method guidance and theoretical reference for the innovative design of the diagnosis and treatment bed, and has certain reference significance.
