Inflation capability: The model allows for the supply of air to inflate both lungs while injecting air into the catheter balloon for secure catheter placement. It also features a marking for the cricothyroid puncture site. Flexible tongue model: The innovative tongue design is flexible, enabling it to work in conjunction with tongue pressure to ensure proper movement of the epiglottis, enhancing glottis visibility during clinical procedures. Comprehensive training operations: Ideal for training and demonstration scenarios focused on oral and nasal endotracheal intubation, with gas supply facilitating realistic inflation for enhanced learning. Suitable for training: This teaching model is designed for students, junior clinicians, and emergency response personnel, providing practical experience in intubation techniques. Integrated monitoring system: The model allows for correct airway insertion during intubation training, featuring electronic display and alarm functions to alert users of improper technique to prevent damage to teeth.
