ABSTRACT:
A tightly coiled, substantially cylindrical wick of compressed, dehydrated, sponge-like material having sufficient rigidity to be inserted endwise into an ear canal will, when hydrated, uncoil and expand radially whereby to substantially engage the inner surface of the ear canal for applying medicament to said inner surface while securing it against accidental or unintentional dislodgment therefrom. When hydrated, a central opening is provided through the uncoiled member through which opening sound waves may freely pass en route to the ear drum.
