Double‑Lumen Anti‑Aspiration Laryngeal Mask Airway

Product Indications
Dual Anti-Aspiration Silicone Laryngeal Mask Airway (LMA) is a high-end supraglottic airway device with dual protective functions: independent gastric drainage + airway/oral secretion aspiration.It establishes an artificial airway and provides ventilation support during clinical anesthesia, emergency treatment and intensive care. It can drain gastric gas and fluid, as well as aspirate secretions at the airway opening, providing a dual barrier against regurgitation and aspiration from the source.It offers a higher level of airway safety for high-risk patients such as full-stomach, emergency and obese patients, and is suitable for operating rooms, emergency departments, ICUs and other scenarios with strict airway safety requirements.

Core Advantages
·Medical-Grade Liquid Silicone Material
Made of high-biocompatibility medical liquid silicone, soft and skin-friendly, with minimal irritation to the pharyngeal and laryngeal mucosa and high patient tolerance. It can withstand autoclaving for repeated use, with high cost-performance.
·Genuine Dual Anti-Aspiration Design for Comprehensive Safety
Independent gastric drainage lumen: timely drainage of gastric contents to reduce the risk of gastric regurgitation and aspiration
Independent airway opening secretion aspiration lumen: direct aspiration of oropharyngeal and airway opening secretions to keep the airway clean and unobstructed
The two protective mechanisms work simultaneously to achieve dual anti-aspiration, with safety far superior to ordinary laryngeal masks.
·Independent Dual-Channel Design, No Interference
Ventilation, gastric drainage and secretion aspiration channels operate independently. Stable ventilation can be guaranteed while drainage and aspiration are performed synchronously, meeting the needs of complex surgeries and high-risk patient airway management.
·Excellent Sealing Performance, Stable and Reliable Ventilation
The cuff fits the anatomical structure of the throat with good sealing effect and low air leakage rate, suitable for conventional surgery, positive pressure ventilation, laparoscopic surgery and other scenarios with high airway pressure.
·Easy Operation & High Clinical Universality
Standardized specifications ensure simple insertion and removal, compatible with mainstream anesthesia machines, ventilators, drainage and aspiration equipment, suitable for medical institutions at all levels.

Scope of Application
Suitable for ventilation in general anesthesia surgery, emergency airway establishment, long-term airway management in ICU,especially for full-stomach patients, obese patients, emergency surgery, laparoscopic surgery and other clinical scenarios with high risk of regurgitation and aspiration.
