Description
Technical Field
[0001] The present invention relates to the technical field of medical training, in particular to a sinking and floating human simulator system. Background Art
[0002] A water rescue manikin is a device specifically designed for use in water rescue training, research, and testing. It's typically designed and manufactured to mimic the human body's shape, weight, density, and other characteristics. Its materials, structure, and performance are designed to closely simulate the state of a real person in water. During rescue training, the manikin can simulate various situations of a drowning person in the water, such as floating, sinking, and struggling. This allows rescuers to practice various rescue techniques and methods, such as using lifebuoys, life jackets, and rescue boats. This helps rescuers accumulate practical experience, improve their rescue capabilities, and enhance their ability to respond to complex situations.
[0003] Current underwater rescue training methods largely rely on mannequins with relatively simple structures and functions. These simple mannequins can only partially represent the basic conditions of a drowning victim and fail to accurately simulate the complex situations encountered in real-life rescue scenarios. Furthermore, during the entire training process, when students make errors in rescue maneuvers or related operations, the lack of advanced monitoring and feedback mechanisms means they rely entirely on the instructor's on-site observation and targeted guidance. This heavily dependent on on-site instructor guidance presents significant drawbacks. Firstly, instructors have limited energy and attention, making it difficult to fully and promptly address every detail of each student's movements. Secondly, manual judgment can be subject to certain subjective factors and errors, making it difficult to objectively and accurately identify errors. This results in relatively low efficiency in underwater rescue training, making it difficult for students to efficiently and systematically master professional skills and correct operational procedures, hindering the rapid development of highly skilled and practical rescue personnel.
