This paper focuses on the problems of naval first aid training such as simple training content, backward training mode and so on, research on the application of VR (virtual reality) technology in naval battlefield first-aid simulation training. This paper introduces the current situation and development trend of VR technology application, analyzes the needs of naval first aid simulation training, designs the naval battle-position first aid simulation training system based on the characteristics of VR technology, constructs the battle-position first aid simulation training simulation model, and designs the naval first-aid simulation training platform based on VR technology. It realizes the first-aid simulation training in an “actualized” background. The study will promote first-aid capabilities of naval health officers, medical sergeant and medical.
