The 6-in-1 Tactical Combat Casualty Care (TCCC) Trainer is a cutting-edge training tool designed to provide a realistic and versatile simulation for medical personnel. It features a Hyper-Realistic® male head and upper torso, anatomically similar to human anatomy, with a skeleton that allows for user-repairable body skin, neck skins, tracheas, and replaceable intraosseous training pucks. This trainer supports a wide range of essential procedures, including Nasopharyngeal Airway (NPA) Adjunct Insertion with oropharyngeal visual confirmation, clearing upper airway obstructions with finger-sweep techniques, and performing surgical airways such as Cricothyroidotomy and Cricothyroidcentesis. Additional procedures include Chest Needle Thoracentesis at four sites (MCL, AAL), Sternal Intraosseous Catheter Insertion, and Proximal Humerus Intraosseous Catheter Insertion, making it an invaluable resource for hands-on, realistic combat casualty care training.
