Analysis of Patent Layout and Development in Digital Nursing for the Elderly Based on LDA Model
Objective To analyze the layout and development of elderly nursing patents in terms of digital health.Methods The digital nursing patents of the elderly in Derwent World Patent Index were searched by computer,and the data were preprocessed,statistically analyzed and the LDA theme model was con-structed by Python.Results A total of 1350 related patents were included,with invention patents account-ing for 51.63％and utility model patents accounting for 48.37％.The number of patent acceptances was on the rise as a whole,and China was dominant.Patent IPC focused on nursing beds,alarms for people with no mobility,measurements for diagnostic purposes,etc.Hot topics on patent included technical equipment and components,nursing and monitoring services,interactive interface and user experience,network and data communication,life assistance and daily management.The development process included the stage of initial development(1997-2012),steady growth(2013-2019),high-speed innovation(2020-2022)and down-ward adjustment(2023-2024).Conclusions The field of digital nursing patents for the elderly is still being tested in the market and developing profoundly.In the future,it will continue to integrate digital technology and provide high-quality services for the elderly.
