Abstract
A fluid such as air is tightly enclosed in a chamber which serves to plug an organic passage such as a person's nasal cavity. The fluid is supplied into the chamber through a tube so as elastically to expand the chamber and thereafter is discharged through a valve device comprising an opening formed in the tube and a valve member which normally closes the opening but can be rolled up on itself so that the fluid in the chamber can flow out through the opening.
