Abstract: With the advancement of medical technology,implantable infusion devices have been increasingly adopted in clinical practice. This study employs the incoPat database for patent literature retrieval and data analysis to systematically examine and organize global and Chinese patent applications related to implantable infusion devices. Emphasis is placed on five key dimensions：annual distribution of applications,geographical distribution of applications,distribution of technical branches,major applicants,and technology evolution routes. The findings aim to provide a reference for future applications of implantable infusion device technologies.

Key words: implantable infusion, patent analysis, global patents
