Research On The Intensive Design Of Stretcher In Disaster Environment

Natural disasters occur in China frequently,including flood,drought,landslide,debris flow,typhoon,hailstone,frost and earthquake,etc.,which cause a heavy loss to human life and property.Ministry of Civil Affairs indicates that in first half of 2016,our natural disasters mainly included flood,hailstorm and geological disaster,while earthquake,low-temperature refrigeration,drought,snow disaster and forest hazard also took place to some extent.All kinds of natural disasters made 68.775 million people be hit by a natural adversity,505 people died of it,71 people missed,1.643 million people were rearranged for emergency,and 1.199 million people should be subsidized for life.Under the indifferent natural disasters,humans are so small and weak.Meanwhile,it also shows that humans have shortcomings in emergency and safety education in natural disasters.Under the background,disaster prevention and reduction becomes an important field in current studies.Stretchers are one of common rescue equipment.With some features of portability,motility,low costs and easy operation,they develop a great role on rescue process.The intensive stretchers can meet multiple demands in rescue.Meanwhile,scene study,user behavior analysis,and innovation of intensive modes can realize multi-territory,multi-function,multi-scene,small volume,rapid transfer and assembly,which conform to future development tendency of rescue equipment.Beginning with the oretical construction and design methods,the author draws the agent of intensification appealing by investigating and analyzing development status of stretchers,conducts the analytical investigation on stretcher design with the intensification philosophy,concludes general principles and methods of the design,and conducts design practice by combining with constructive theory and design strategies,hoping to verify operability of conclusions.
