Description
Technical Field
The utility model relates to the field of medical education, in particular to a visual laryngoscope system for tracheal intubation teaching and examination.
Background
The trachea intubation is a rescue technique commonly used in clinic, is also a common means for managing the air passage of an anesthesia department, has extremely important significance for rescuing and treating critical patients and ensuring effective ventilation and unobstructed respiratory tract of the patients in the perioperative period, and is one of necessary skills of all clinicians. More and more majors have all developed the teaching of trachea cannula course, and at traditional teaching in-process, the teacher often all relies on feeling and experience to operate and impart knowledge to students in the area of teaching, and because the direct laryngoscope of tradition that used ever can only one-man operation, and the field of vision can only be through patient's oral cavity, the pharyngeal cavity direct vision laryngeal exposure condition, and visual scope is very little, often can only supply alone to see of operator. The consequence of this is that when the teacher with teaching is operating in person, the students are difficult to see the process of putting the laryngoscope and the exposure condition of the throat, even if the teacher with teaching is put the laryngoscope at a proper position and the visual field is left for the students to observe, the students are easy to shift to affect the observation; when students operate by themselves, the teacher with the teacher can hardly see the process of putting the laryngoscope in, the problems in the operation process can not be found, and the correction and guidance can not be carried out in a targeted manner, so that the teaching effect is greatly reduced, unnecessary injury can be brought to patients, and the operation risk is increased.
In recent years, many teachers use a visual laryngoscope to teach endotracheal intubation, and since the visual laryngoscope can transmit the visual field at the front end of the laryngoscope to a display screen, teachers can introduce relevant anatomical structures and characteristics thereof in the airway of students and demonstrate specific steps of endotracheal intubation operation under the guidance of the visual laryngoscope. By the method, students can get familiar with the anatomical structure of the throat more quickly and master the related operations of visual endotracheal intubation under the laryngoscope.
