Description

Technical Field

[0001] The invention belongs to the technical field of endotracheal intubation training, and in particular relates to an endotracheal intubation training model for anesthesia. Background Art

[0002] In the field of medical respiratory emergency, tracheal intubation is an effective method to maintain unobstructed breathing and thus perform respiratory management. It is also an important measure for anesthesia and emergency rescue. Its main function is to ensure unobstructed breathing to prevent cell necrosis. In order to ensure that the patient's breathing is unobstructed, it is necessary to promptly suck out obstacles such as sputum or blood in the trachea to prevent carbon dioxide accumulation. Tracheal intubation is generally used to eliminate the above problems. Due to the importance of tracheal intubation surgery, the operation level of medical staff is required to be high. Clinical operations generally use blind intubation. The success of this type of technical operation depends entirely on the experience of the operating medical staff. There are also many inconveniences in actual medical training, and there is a lack of effective intubation training methods. Therefore, there is an urgent need for a method and system for tracheal intubation simulation training using virtual reality technology and mixed reality technology to solve the problem that the existing tracheal intubation training method is not effective, so as to adapt to the needs of various tracheal intubation training scenarios, provide trainees with immersive experience, and lay a solid foundation for them to enter real clinical surgery; Since most patients are lying down during tracheal intubation, in the actual teaching demonstration process, it is not convenient for students to watch and learn using a lying mold for teaching. If the teaching is conducted vertically, teaching errors are prone to occur because the gravity direction of the tracheal intubation when operating on a platform patient is inconsistent with the gravity direction of the vertical model. This leads to a large difference in the control force and deflection force required by medical staff between the two. Therefore, the current teaching demonstration tracheal intubation mold does not have a demonstration model that is convenient for teaching demonstration and students to watch while ensuring the authenticity of the demonstration conditions.
