Optimization Design of Emergency Quick Fixation Device Based on ANSYS Workbench / 中国医疗器械杂志

ABSTRACT

OBJECTIVE@#A rapid fixation device is developed to solve the problems of emergency fixation and transportation of patients with spinal injury.@*METHODS@#Through the analysis of the function,3D modeling design, finite element analysis and optimization design based on ANSYS Workbench, tensile strength verification experiment, we produced the prototype, and tested it, conducted a simulated rescue experiment.@*RESULTS@#The fixation device designed can meet the demand of spinal injury patients for safe rescue after accidents, and the quality of the rapid fixation device was lighten by about 30% without reducing the intensity.@*CONCLUSIONS@#The method based on optimal design can obviously improve the structure design, and has reference significance for other related rescue equipment design.
