| 目的 采用多弹簧组变阻尼结构模拟真实的人体胸腔生物力学特性，结合原有的电子反馈系统设计出一款基于仿真胸腔生物力学特性的新型心肺复苏训练模拟人，并测试其在心肺复苏（cardiopulmonary resuscitation，CPR）教学中的应用效果。方法 选取海军军医大学2019级五年制临床医学专业的60名本科学员作为研究对象，分成试验组和对照组，每组30名。对照组使用传统模拟人进行CPR培训，试验组在对照组基础上应用新型模拟人进行CPR培训。培训结束后对两组人员分别进行单项技能考核。单项技能主要是徒手进行心肺复苏操作，包括人工呼吸与胸外按压。比较两组的CPR理论和技能操作考核情况及对教学方法的满意度。采用SPSS 23.0进行统计学分析。结果 试验组学员单项技能操作考核成绩为（54.33±3.09）分，优于对照组学员（52.33±3.08）分，差异有统计学意义（P <0.05）。调查问卷显示，试验组学员对于新型模拟人的教学训练效果评价较好。结论 新型心肺复苏模拟人相比传统模拟人，更能够模拟真实人体的心肺复苏急救场景，可以有效提高医学学员规范化培训CPR教学效果，助力我国心肺急救技术的标准化、规范化、普及化工作。 |

| Objective To simulate the biomechanical characteristics of the real human thoracic cavity with a multi-spring group variable damping structure, and to design a new cardiopulmonary resuscitation training manikin based on the simulated thoracic biomechanical characteristics combined with the original electronic feedback system, and to test its application effect in cardiopulmonary resuscitation (CPR) teaching. Methods A total of 60 undergraduate students majoring in five-year clinical medicine of Batch 2019 in Naval Medical University were selected as the research objects and were randomly divided into the experimental group and the control group, with 30 students in each group. The control group used the traditional manikin for CPR training, and the experimental group used the new type of manikin for CPR training based on the control group. After the training, the two groups of personnel were assessed for single skill. The single skill was mainly manual CPR operations, including artificial respiration and chest compressions. The theory and skill operation assessment of CPR and satisfaction for teaching method in the two groups were compared. SPSS 23.0 was used for statistical analysis. Results The students in the experimental group scored (54.33±3.09) points in the single skill operation assessment, which were significantly better than that of the students in the control group [(52.33±3.08) points], and the difference was statistically significant (P<0.05). The follow-up questionnaire showed that the students in the experimental group had a better evaluation of the teaching and training effect of the new type of manikin. Conclusion Compared with the traditional manikin, the new CPR manikin can simulate the CPR emergency scene of the real human body, which can effectively improve the CPR teaching effect of standardized training for medical students, and help the standardization, normalization, and popularization of CPR technology in China. |
