Nasal feeding surgery virtual training method and system

Abstract

The invention discloses a nasal feeding surgery virtual training method and system. The nasal feeding surgery virtual training method comprises the following steps of login, mode selection, case selection, preoperative preparation, preparation before catheterization, marking of a gastric tube, intubation, wiping, confirming the position of the gastric tube, perfusion of food, extubation, and ending; the marking of the gastric tube comprises the steps of detecting whether the intubation length is required to measure and whether the measurement is correct, and marking the gastric tube accordingto the measured intubation length; the intubation comprises the steps of lubricating the anterior segment of a virtual gastric tube, detecting that a simulated gastric tube is inserted from a nostrilof a model human, detecting the position of the simulated gastric tube passing through the model person during the intubation, and controlling the virtual patient to stop swallowing if a stop swallowing instruction is received. According to the sputum suctioning virtual training method and system, the simulated nasal feeding surgery operation is performed through prompt and timely feedback and guidance; and the training method is designed according to the operation process of the actual sputum suctioning, therefore, the realism of the simulated training is increased, and the airway managementoperation ability of the operator is improved.

Description

technical field [0001] The invention relates to a medical teaching and training system, in particular to a virtual training method and system for nasal feeding. Background technique [0002] Nasogastric gavage (nasogastric gavage) is to send a gastric tube into the patient's stomach through the nasal cavity, and feed food into the patient's stomach through the gastric tube. It is usually used for patients who are comatose or unable to eat by themselves. Nasogastric feeding is one of the basic skills that emergency department and critical care medicine doctors must master. Among them, nasal feeding is a frequently used operation in clinical work. Students rarely have the opportunity to train clinically; the traditional manipulator training process is incomplete, and some training methods do not match the actual situation; there is no monitoring and no error feedback during the operation process of the students; the existing model training steps are incomplete, only the intub...

Problems solved by technology

Students rarely have the opportunity to train clinically; the traditional manipulator training process is incomplete, and some training methods do not match the actual situation; there is no monitoring and no error feedback during the operation process of the students; the existing model training steps are incomplete, only the intubation link, lack of preoperative Preparation, preoperative communication preparation and other steps; the method of determining the position of the catheter during the operation is to directly observe the contraction and contraction of the exposed lung and stomach structure, which is inconsistent with the actual auscultation method; the traditional model is "dead", and will not be given to students according to different operations Corresponding feedback; skill teaching must be taught by teachers in the classroom, and daily training is difficult to carry out; traditional training is only skill practice and lacks the cultivation of clinical thinking
