Title:
Laryngeal Mask Device
Document Type and Number:
WIPO Patent Application WO/2017/201645
Kind Code:
A1
Abstract:
A cuff structure (20b) for a laryngeal mask device (100) comprises an inner-layer cuff (20b1) that defines an annular main chamber of the cuff structure (20b) to be inflated or self-inflated, and an outer-layer cuff (20b2) that surrounds the inner-layer cuff (20b1). The outer-layer cuff (20b2) has a higher elongation rate and a thinner thickness than the inner-layer cuff (20b1), so that the cuff structure (20b) can comply with the tissue structure of the patient very even. With this dual-layer cuff structure (20b), the leakage resistance of the laryngeal mask device (100) will be improved.
