The simple half-body cardiopulmonary resuscitation (CPR) manikin is a teaching device used for basic first aid training, mainly for the learning and practice of CPR skills. This model has a simple structure, including key anatomical parts such as the head, chest and upper body. It can truly reproduce the rebound sensation of chest compression and the correct physiological position, enabling trainees to master the standard compression depth and frequency during training.

In teaching, trainees can repeatedly practice operations such as external chest compressions, artificial respiration, and airway opening through this simulation manikin, form muscle memory, and improve their proficiency in emergency handling. It is easy to operate and portable, and is suitable for various scenarios such as schools, communities, hospitals and public safety training.

The simple half-body cardiopulmonary resuscitation (CPR) manikin not only helps beginners master the essentials of first aid, but also can be used to popularize CPR knowledge and enhance the public's self-rescue and mutual rescue capabilities. Through repeated training, the response speed and operational accuracy of emergency rescue can be effectively enhanced, which is of great significance for improving the survival rate in emergencies.
