The simplified half-body cardiopulmonary resuscitation simulation manikin, characterized by its concise structure and intuitive operation, is one of the most commonly used teaching devices in basic first aid training. Its main advantages are first reflected in its moderate cost and ease of popularization, which can meet the large-scale training needs of schools, communities, enterprises, institutions and public first aid publicity activities. The model is equipped with the simulated chest rebound and resistance required for correct external chest compression, which can help learners master the standard requirements for compression depth, frequency and hand position. Some models are equipped with simple press feedback mechanisms, such as sound prompts or chest rebound indicators, making it easier for beginners to determine whether the operation is up to standard.

In addition, the half-body structure is easy to move and quickly arrange, making it suitable for on-site drills and simultaneous training of multiple groups. As the operation process focuses on compression and artificial respiration, the learning curve is more friendly, which is conducive to public learning and enhancing first aid awareness. The model is durable and reusable, and can train a large number of people in a short time. It is an important tool for promoting and popularizing cardiopulmonary resuscitation skills.
