A mixed reality based training method and system for esophageal electrode intubation

Abstract

The invention relates to a mixed reality-based esophageal electrode intubation training method and system. The method includes constructing a human esophagus model, initializing the position of the virtual esophageal electrode and calibrating the standard intubation track of the virtual esophageal electrode; Information to adjust the actual position of the virtual esophageal electrode in the human esophagus model, and determine the feedback friction of the trainer according to the actual position; display the deviation information between the actual position and the standard intubation track to guide the trainer to adjust the intubation operation. The present invention adjusts the actual position of the virtual esophageal electrode in the human esophagus model by constructing the human esophagus model, and according to the operation signal generated by the trainer receiving the esophageal electrode intubation operation of the trainer, and at the same time determines the feedback friction force of the trainer according to the actual position , it is convenient for the trainer to experience the intubation process visually and tactilely, it is beneficial for the trainer to adjust the intubation operation in time, quickly master the intubation skills, and improve the learning efficiency.

Description

technical field [0001] The invention relates to the technical field of mixed reality, in particular to a mixed reality-based esophageal electrode intubation training method and system. Background technique [0002] Body surface electrocardiogram is the gold standard for diagnosing arrhythmia, and it has provided timely, accurate and reliable diagnostic basis for clinical diagnosis and treatment for one hundred years. However, some arrhythmias can only be described when the patient attacks, and the recording point is limited to the body surface, resulting in unclear P waves, so the specific origin of the arrhythmia or the sequence of cardiac activation cannot be clarified, and it is difficult to correct for some complex arrhythmias diagnosis. [0003] Both the esophagus and the heart are located in the mediastinum, with the heart anterior and the esophagus posterior, separated only by the pericardium. The anterior wall of the lower end of the esophagus is closely adjacent t...

AI Technical Summary

Problems solved by technology

[0005] In the prior art, medical staff acquire the skill of esophageal electrode intubation by intubating the patient’s esophagus through the mouth / nasal cavity, so for medical staff who are not skilled in intubation skills, the success rate of intubation is low, and intubation is prone to occur. Deviations such as mistakenly entering the trachea cause extreme discomfort to the patient, especially if the insertion position of the esophageal electrode cannot be accurately grasped, which will easily lead to inaccurate ECG parameters and affect the diagnosis of the patient's condition. There is no equipment for intubation training for patients' esophagus in existing technologies, which is not conducive to medical staff learning and acquiring esophageal intubation skills
