新质生产力视角下中国智能健康医疗专利的创新态势研究OACSTPCD

Objective To discuss the development trend of new quality productivity in the field by analyzing the patent information in the field of intelligent health and medical care and measuring the technological innovation ability in the field.Methods The intelligent health and medical care patents from the establishment of the database to December 31,2023 were obtained from the Patent Search and Analysis system of China National Intellectual Property Administration,and the basic information such as the time trend of the number of patent applications,the distribution of applicant types and regional layout were statistically analyzed.The co-occurrence network and BERTopic theme clustering method were used to deeply analyze the technological themes of patents and their evolutionary trends.Results The number of patent applications in the field of intelligent health and medical care in China increased exponentially,from the first patent application in 1988 to the cumulative application of 12217 patents in 2023.It could be divided into four periods:budding exploration period(1988-2010),steady growth period(2011-2015),rapid rise period(2016-2020)and innovative prosperity period(2021-).The regions and types of the first applicants differed significantly.The key technologies were mainly concentrated in G16H(healthcare informatics)and A61B(diagnostics;department of surgery;identification)field.The common topics included artificial intelligence systems,AI recognition,storage media,machine learning,recommendation models,cardiovascular diseases and mental disorders,and CT image processing.In terms of technological evolution,A61B always occupied an important position in the entire development process,from budding exploration period,steady growth period,rapid rise period to innovative prosperity period,the relevant patent topics continued to expand in breadth and depth,from the early focus of clinical practice application,and gradually penetrated into many fields such as health management,disease prevention,rehabilitation and nursing.Conclusion The new quality productivity in the field of health and medical care represented by artificial intelligence is gradually taking shape and accelerating its development.In the future,the development of the intelligent health and medical industry can be comprehensively promoted from multiple dimensions such as policy orientation,scientific research investment,and talent reserve to achieve further innovation and upgrading of productivity in the health and medical field.
