模拟肺动脉空气栓塞演示模型的制作及教学应用

目的：设计制作模拟肺动脉空气栓塞演示模型，解决病理解剖学肺动脉空气栓塞实验教学的难题．方法根据局部血液循环障碍和空气栓塞发生的原理设计制作模型，以本校护理专业学生为研究对象，将223名学生随机分为动物实验对照组及模型教学研究组，比较两组教学效果．结果研究组实验考试成绩高于对照组（P〈0.05）．结论使用模拟肺动脉空气栓塞演示模型教学可以明显提高学生实验考试成绩，并能反复重复使用，激发学生实验学习兴趣，降低教学成本，提高教学质量．

Production and Teaching Application of Simulated Pulmonary Air Embolism Demonstration Model

Objective To design simulated pulmonary air embolism demonstration model,so as to solve the problem of pathological anatomy of pulmonary air embolism in experiment teaching. Methods According to the principle of the disturbance of local blood circulation and air embolism, we designed a pulmonary air embolism model. We took 223 school nursing students as the object of this study,and randomly divided them into 2 groups：animal experiment teaching group and model control group,then we compared the teaching effect between the two groups. Result The test scores of students in the animal experiment teaching group were higher than control group （P〈0.05） . Conclusion The use of simulated pulmonary air embolism demonstration model teaching can improve the students’experimental test scores,and can be repeatedly used,stimulate students＆#39; study interest,reduce the cost of teaching,and improve the teaching quality.
