Intelligent immersed teaching system and device used for nasogastric tube operating training

Abstract

The invention discloses an intelligent immersed teaching system and device used for nasogastric tube operating training. A virtual human body structure is constructed through a virtual reality modeling technology, students complete a nasogastric tube manual placing step on the system and achieve cognition training. The process achieves visualization, and physiological response of a patient is simulated for students through touch sense feedback and stereo sound effects. Action of a student during the whole nasogastric tube manual placing process is subjected to quantitative evaluation, which helps the student to raise clinic operation skills. Autonomic and high-efficiency training of students is achieved, sensory cognition and clinic communication skills of learners are raised, and data support is provided for teaching planning.

Description

technical field [0001] The invention relates to the field of virtual reality applications, and more specifically relates to an intelligent immersive teaching system and device for nasogastric tube operation training. Background technique [0002] Nasogastric tube (NGT) is a standard medical device commonly used in outpatient and hospital settings, and its placement is a common part of the nursing process. However, nasogastric tube placement is an action that cannot be completed with the aid of human visual perspective, and the positioning of the tube body cannot be directly recognized by the naked eye. Therefore, fatal medical accidents and complications caused by negligent nasogastric tube insertion occur from time to time . [0003] Under the current technical conditions, nasogastric tube placement in nursing teaching is usually carried out in ordinary classrooms using real subjects for operational training, and serious medical accidents may happen to these real subjects....

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved by the present invention is that, aiming at the defect that the real nasogastric tube operation training in the above-mentioned nursing teaching process of the prior art may lead to serious medical accidents, and the dummy model cannot simulate the physiological response of the patient, a method for An intelligent immersive teaching system and method for nasogastric tube operation training. The system is based on virtual reality (VR) and intelligent computing software installed on a personal computer platform and a set of external tactile feedback equipment. Nasogastric tube is manually placed to achieve cognitive training. During the training process, the system divides the virtual human body area where the tube body is located according to the preset clinical data, and simulates the patient's physiological response to the trainees through tactile feedback and stereo effects. The movement during the whole process of nasogastric tube placement will be quantitatively evaluated for trainees to improve their clinical operation skills
