Description
An i-gel 4 is a green, medium-adult size supraglottic airway device, a single-use medical tool used for breathing assistance, featuring a soft, gel-like cuff that forms a seal in the throat without inflation, designed for quick, reliable insertion to help patients breathe in emergencies or anesthesia, with the size 4 for adults weighing 50-90kg.
Key Features & Appearance:
