Research status and development tendency of unmanned aerial vehicles for casualty evacuation / 医疗卫生装备

ABSTRACT

Objective To explore the application of unmanned aerial vehicles (UAVs) technology for casualty evacuation in disaster rescue.Methods The research status of casualty evacuation using unmanned aerial vehicles was described in the disaster medical rescue,and several UAVs involved in casualty evacuation were introduced.According to different dynamic structures,casualty evacuation UAVs were divided into four types,such as traditional rotor helicopter,multi-rotor aircraft,ducted fan aircraft,compound aircraft.Meanwhile,the load capacity and flight speed of involved UAVs were analyzed.Results The advantages of casualty evacuation UAVs in the previous researches related were summarized,with the problems and technical difficulty discussed.Furthermore,the development tendencies of casualty evacuation UAVs were predicted.Conclusion Casualty evacuation UAVs can transport the wounded to the professional medical institutions outside of the disaster scene instead of rescue crews,to reduce the casualty rate of rescuers and avoid secondary damage of the injured personnel,with accurate point to point casualty evacuation.
