Visually Open Anatomical Design: One side of the tracheal intubation model is fully open to clearly show nasal cavity, tracheal structure, and cervical spine movement, making it easier for teaching demonstration and student observation Electronic Alarm & Operation Feedback: Alerts automatically when laryngoscope exerts excessive pressure on teeth; correct intubation provides electronic indication and simulated lung inflation, while esophageal misinsertion triggers an alarm and simulated stomach distension Realistic Clinical Simulation Features: Designed with one normal pupil and one dilated pupil for comparison, and clearly marked cricothyroid membrane puncture location for comprehensive clinical skill training Dual Oral & Nasal Intubation Training: Supports both oral and nasal tracheal intubation practice, ideal for standardized skill training in airway management, emergency care, and asphyxia resuscitation Wide Application in Medical Education: Perfect for medical universities, labs, training centers, and healthcare institutions; an essential teaching model for tracheal intubation skill training and first aid education
