随着医疗护理知识更新速度加快，学生需要掌握的知识和技能也在飞速增加。各类在线教育方式使学生获取的学习资源呈现多样化、便捷化，但这也导致了知识的碎片化。知识图谱能够有效地整合并呈现各个领域的知识，为护理教学提供更加全面与系统的理论基础和知识支撑。该研究以内科护理学课程中的支气管哮喘患者护理章节为例，从教学内容结构化、模式层和数据层设计、知识抽取和知识存储等方面构建了知识图谱，可为解决知识碎片化问题提供思路，为构建医学课程知识图谱提供方法学参考。

With the accelerating pace of updates in medical and nursing knowledge，the knowledge and skills that students need to master are also increasing rapidly. Various online education methods has provided students with diverse and convenient learning resources，but there may also lead to problems such as fragmented knowledge. Knowledge graph can effectively integrate and present knowledge from various fields，providing a more comprehensive and systematic theoretical basis and knowledge support for nursing education. Therefore，this study has undertaken the bronchial asthma chapter in Medical Nursing as an example and constructed a digital teaching model based on a knowledge graph from the aspects of structured teaching content，design of model layer and data layer，knowledge extraction and knowledge storage. This study aims to provide research ideas for solving problems such as fragmented knowledge and provides methodological references for constructing knowledge graphs of medical courses.
