In contemporary society, the design of healthcare space does not just stop at the level of basic functional layout and the setting of medical equipment. Humanized intervention is getting more and more attention from the relative stakeholders , such as patients with families, medical staff, etc. In order to meet the dual needs of the users on the physical and psychological levels, in this study I introduce the USS system to realize humanized intervention. USS means User - Space - Story, which can be applied to any functional type of architecture, and the medical space is not an exception. In this triangular framework, on the one hand, I sorted out the interrelationships between the three elements, that is, the two of them have corresponding needs and influences on each other.
