Abstract

See full text

A manufacturing process to produce a laryngeal mask substantially as described in UK Patent GB2205499B consists in a mould which manufactures the inflatable annular ring formation of the device in an inverted form. This allows a more rigid core in the cavity mould or alternatively a dip-moulding process, which in turn, permits greater accuracy in control of wall thickness. An alternative form of the mould eliminates the need to assemble a further component, by incorporating the latter into the same single moulding process. And in a further alternative embodiment, the same single moulding process additionally provides an integrally formed inlet for oesophagus drainage, independent of the larynx-venting function of the mask per se.
