Abstract

See full text

A shell of flexibly pliant material is in peripherally sealed engagement with the inflatable ring portion of a laryngeal mask such that when both the mask ring and the space within the shell are inflated, i.e., after patient installation of the mask in deflated condition, a back cushion is established with large-area self-adapting conformation to the back wall of the pharynx, so that inflation pressure in the back cushion not only positions back contours of the mask per se at offset from the back wall of the pharynx but in addition establishes a large area of uniformly distributed forward pressure on the mask per se, resulting in a pneumatically loaded application of the inflatable ring of the mask, into enhanced sealing conformance to and engagement with the laryngeal inlet.
