基于专利数据的我国公立康复医院科技创新能力分析OA北大核心CSTPCD

Objective To analyze the technological innovation capability of public rehabilitation hospitals in China by sorting out patent application data.Method A total of 924 patent applications by 61 public rehabilitation hospitals in China from 1989 to 2022 were collected and sorted.Quantitative analysis was used to examine data on trends,legal status,and regions of these patent applications.Cluster analysis was applied to construct a patent cooperation network,together with natural language processing utilized in extracting patent text keywords and calculating their frequency.Results The number of patent applications by public rehabilitation hospitals in China increased year by year from 1989 to 2022,reaching a peak of 674 utility model patents(72.94%).In terms of patent legal status,there are 535 valid patents(57.90%),117 patents under review(12.66%),and 272 invalid patents(29.44%).The top three regions with the highest number of patent applications are Beijing,Shanghai,and Jiangsu.Three Grade-3 hospitals,namely China Rehabilitation Research Center,Beijing Xiaotangshan Hospital,and Shanghai Yangzhi Rehabilitation Hospital,each have over 100 patent applications.Patent cooperation network analysis shows limited cross-regional technical cooperation among public rehabilitation hospitals in China.Currently,three large patent inventor cooperation networks have been formed.Various phases of patent development focus on different aspects of research and development technologies:the incubation phase emphasizes functional compensatory rehabilitation aids,the budding phase focuses on rehabilitation training equipment,and the development phase centers on intelligent rehabilitation training aids.Additionally,physical therapy rehabilitation equipment based on traditional Chinese medicine has been further developed.Conclusion The research and development of patent technology in public rehabilitation hospitals in China has entered its development phase,with intelligent assistive devices becoming a key direction.Grade-3 public rehabilitation hospitals play an important role in scientific and technological innovation,with Beijing and Shanghai as the major players.Public rehabilitation hospitals face challenges such as insufficient output capacity for high-value innovation achievements,low efficiency in technology transformation,and inadequate synergic innovation capabilities.
