Portex® Soft Seal® Laryngeal Mask

Portex® Soft Seal® Laryngeal Mask


The Portex® Soft Seal® Laryngeal Mask features the exclusive Soft Seal® Cuff which is less permeable to nitrous oxide than that of re-usable masks, reducing increase in pressure and minimising potential trauma.

The cuff, combined with the higher atrium, helps to provide an improved seal. The Portex® Soft Seal® Laryngeal Mask is designed to avoid the risk of blockage without the need for obstructive epiglottis bars, allowing easy access for flexible fibre optic devices and fibre optic-guided placement of endotracheal tubes.
