Abstract
A hollow-cylindrical tube of dehydrated, regenerated cellulose sponge material is tightly compressed to provide an elongate member of minimal diameter having sufficient rigidity to be inserted endwise into a body opening where it will, when moistened, expand radially whereby to substantially engage the inner peripheral walls of the opening for securing it against accidental or unintentional dislodgement therefrom. When used in association with an ear canal an axial opening through the expanded member permits sound waves to reach the ear drum. The device can be used to apply medicament by expanding the compressed tube with a liquid medicament.
