Research on Electromagnetic Positioning Detection Method for Tracheal Intubation Trajectory
摘要
Abstract
Objective To avoid the injury of patients caused by intubation errors,to study the electromagnetic positioning detection method of tracheal intubation trajectory,so as to improve the success rate and efficiency of intubation operation and provide key technical support for the development of automated tracheal intubation robot.Methods The correct and incorrect tracheal intubation curves were collected based on the electromagnetic position tracker and the human head and neck model.The curve data were processed and screened using MATLAB.The optimal paths of the correct and incorrect tracheal intubation curves were calculated based on the dynamic time warping(DTW)algorithm.The DTW algorithm was then used to calculate the similarity between the correct and incorrect optimal paths and the curve to be detected.The correctness of this intubation operation was determined by comparing the similarity values.Results The similarity values between 120 groups of intubation operations and the correct and incorrect optimal paths differed significantly,which could be used to determine whether the intubation operation was correct or not.The system was tested using 50 sets of curves,and the success rate was 100%.Conclusion The tracheal intubation trajectory detection system can detect whether the intubation process is correct,assist doctors in operation,improve intubation efficiency,and avoid accidental injury to patients during intubation.关键词
