Abstract

A manufacturing process to produce a laryngeal mask (10) substantially as described in UK Patent GB2205499B consists in a mould (20, 21, 23, 24) which manufactures the inflatable annular ring (13) formation of the device in an inverted form. This allows a more rigid core (20) 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 eliminated the need to assemble a further components 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.
