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.

Claims

1. A device for dispensing a pharmaceutical formulation into body cavities which comprises:

a tube having a plurality of lengthwise, elongated ribs at one end, said tube being disposed to incorporate said formulation on said ribs;

a cylindrical rod slidably positioned within said tube and connected to said tube at the end containing said elongated ribs, the distal end of said tube being essentially flat is shape and comprising thumb actuating means, the free end of said rod and the distal end of said tube containing two opposed slots for the receipt of finger actuating means comprising at least one moveable finger support means, said cylindrical rod being disposed in pressure responsive relation to said tube such that pressure applied between the thumb actuating means and said finger acutating means causes the elongated ribs to distend, thereby depositing the pharmaceutical formulation on the interior walls of the cavity.
