Key Features — Dual Lumen, Dual Channel
Main ventilation channel — connects to the anesthesia machine or ventilator to deliver oxygen and anesthetic gases.
Independent gastric drainage channel — a parallel channel built into the tube accepts a gastric tube directly, allowing gastric suction and isolation of reflux, significantly reducing the risk of aspiration — comparable to second-generation drainage LMA safety standards.
Integrally moulded bite block with lateral stabilising wings — self-retaining wings on both sides of the tube prevent rotation and displacement in the oral cavity; the built-in bite block prevents the patient from biting down and occluding the airway on emergence.
