Abstract
A forming tool member which presents a contoured peripherally continuous concave recess within the confines of an exposed upper surface of the tool. This concave recess conforms generally to the contour of the inflatable ring of a laryngeal mask in its inflated state. A second or closure member (or force-application member) has a convexly contoured lower peripheral surface conforming generally to a predetermined or desired optimum shape of the ring in its deflated state, so that the predetermined shape of the deflated ring can be achieved by squeezing compression of these two members against an interposed deflatable ring in the course of fully deflating the ring. Releasably engageable elements of the two members retain a clamped and compressed condition of the fully deflated ring, in instant readiness for emergency use of the involved laryngeal mask.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
