目的 分析数字健康背景下老年护理专利的布局与发展趋势。方法 计算机检索Derwent世界专利索引老年数字护理专利，使用Python进行数据预处理、统计分析和构建隐含狄利克雷分布（latent dirichlet allocation，LDA）主题模型。结果 共纳入相关专利1350项，发明专利占51.63%，实用新型专利占48.37%。专利受理数量整体呈上升趋势，我国占主导地位。国际专利分类集中在护理床、响应无活动能力者的报警器、用于诊断目的的测量等。专利热点主题有技术设备与组件、护理与监测服务、交互界面与用户体验、网络与数据通信和生活辅助与日常管理。发展脉络包括初步发展阶段（1997-2012年）、稳定增长阶段（2013-2019年）、高速创新阶段（2020-2022年）和下降调整阶段（2023-2024年）。结论 老年数字护理专利领域正处于市场验证与深入发展阶段，未来老年护理领域将继续融合数字技术纵深发展，以提供高质量的老年护理服务。

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 constructed by Python.Results A total of 1350 related patents were included,with invention patents accounting 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 downward 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.
