ABSTRACT:
A device for introducing pharmaceutical formulations into a body orifice is described. The device consists of a hollow tube constructed of a rigid but flexible material which is closed at at least one end. A freely sliding, rigid tube or rod is contained within the hollow tube and is attached to one end of it. The outer tube is slit longitudinally near the end where the two tubes are joined to form a plurality or uniform distensible ribs which distend or flex when pressure is applied to the end to which the inner tube is attached.
