Product overview This intubation training model is a PVC die cast simulator designed for oral and nasal tracheal intubation practice. The model combines standard human anatomy with visible, realworld demonstration features to support stepwise skills training from basic to advanced techniques. It is constructed for realistic appearance, durable use, and easy disassembly for inspection and maintenance. Key features and functions Material and construction: Made of PVC plastic using a die casting process for a lifelike look, stable structure, and long service life. Components are designed for convenient disassembly and reassembly. Visual feedback: Includes a side visual function that lets trainees observe tube placement during practice, showing both correct and incorrect paths. Correct insertion demonstration: When the tube is inserted into the airway, the model demonstrates lung expansion with air supply to the lungs. Incorrect insertion demonstration: If the tube is inserted into the esophagus, the model shows stomach inflation when air is supplied, allowing trainees to recognize and correct misplacement. Tube fixation and airbag function: Air can be injected into the tube airbag fixing tube to simulate tube cuff inflation and demonstrate fixation techniques. Anatomical fidelity: Combines standard human anatomy with practical visual cues to support realistic handson training. Benefits Teaches immediate recognition of correct versus incorrect tube placement through visible, mechanical responses. Supports progressive skill development from basic intubation steps to more advanced technique refinement. Facilitates instructorled demonstrations and selfguided practice with clear, repeatable feedback. Durable and serviceable construction reduces downtime and simplifies cleaning and part replacement. Use scenarios and applications Classroom skills labs: Use for instructorled demonstrations and student practice of oral and nasal tracheal intubation techniques. Emergency airway training: Practice recognizing esophageal intubation and confirming airway placement under simulated conditions. Prehospital and simulation drills: Integrate into scenariobased training for paramedic, EMT, nursing, and respiratory care education. Specifications and compatibility Material: PVC plastic, die casting process. Primary functions: Oral and nasal tracheal intubation training, side visual observation, lung expansion simulation, stomach inflation on esophageal insertion, and tube airbag fixation simulation. Design attributes: Lifelike appearance, reasonable internal structure, convenient disassembly, and durable construction. This model is intended as a practical training tool to provide realistic visual and mechanical feedback during airway management practice.
