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. 本发明公开了一种用于鼻胃管操作实训的智能沉浸式教学系统及装置，通过虚拟现实建模技术构建出虚拟人体结构，学员通过在系统上完成鼻胃管手工放置步骤以实现认知训练，该过程不仅实现了可视化，且通过触觉反馈和立体声效向学员模拟患者的生理反应，学员在整个鼻胃管放置过程的动作将予以量化评估，供学员改进临床操作技巧，实现了学员的自主高效实训，提升了学习者的感官认知以及临床沟通技巧，同时也对教学计划的制定提供数据支持。
