Ambu AuraOnce laryngeal mask #5 321 500 000
The Ambu AuraOnce Laryngeal Mask size 5 (321 500 000) is a single-use, anatomically curved airway device. It is made of phthalate-free PVC to ensure safety and biocompatibility. The mask’s soft, thin cuff provides a reliable seal with low mucosal pressure.
Designed for adult patients (approximately 70–100 kg), the AuraOnce size 5 offers fast, atraumatic placement due to its anatomically correct curve molded directly into the airway tube. The reinforced tip helps resist folding during insertion, improving placement reliability and reducing leaks. The soft, single-piece cuff ensures a secure seal even at low inflation pressures, minimizing risk of trauma. This mask is MR-safe and made for single-use, making it convenient for routine anesthesia or resuscitation without the burden of sterilization.
