Abstract: Objective To design a lifting aid to enhance the loading and unloading efficiency of casualties in emergency rescue.Methods The lifting aid was composed of a lifting mechanism,a motorized control unit and a manual control unit,which used a pulley set to enhance working efficiency,achieved lateral patient translation via a separable and movable sleeping pad and realized electric and manual control by a motor and lever respectively.An equivalent scaled-down model was made to test the forces at the lever under 0,5,10,20 and 30 kg bearing weights to verify the performance of the aid.Results The trend of the tensile force exerted on the lever under five sets of different loads was in accordance with the results of the theoretical analysis.Conclusion The lifting aid with easy operation ensures patient safety and enhances the loading and unloading efficiency while saving the workload.[Chinese Medical Equipment Journal,2024,45(4):111-115]
