Abstract
A therapeutic-substance carrying/administering appliance includes a cylindrical outer sheath; a slide member installed in the cylindrical outer sheath to be slidable therein; and a sheet supporting member, connected to a distal end of the slide member and made of a resilient material, for supporting a sheet-shaped therapeutic substance. The sheet supporting member is held in a flat unrolled shape in a free state in which the sheet supporting member projects outwardly from a distal end of the cylindrical outer sheath. When the sheet supporting member is in the free state, sliding the slide member in a retracting direction causes the sheet supporting member to contact the distal end of the cylindrical outer sheath, and subsequently further moving the slide member in the retracting direction causes the sheet supporting member to be retracted into the cylindrical outer sheath while being deformed into a tubular shape.
