Abstract
Abstract The present invention provides a throat pack comprising a resilient moulding of polymeric foam material shaped and adapted for insertion into and occlusion of the oro-pharynx or laryngo-pharynx or both. An exposed region of the foamed material, at least in the anterior surface of the moulding, may be useful in absorbing fluids. One or more safety tapes are incorporated in the pack so as to extend outwards through the mouth.
