Abstract
Device and method for preparation of a condom by a user. The device defines a circular surface adapted to receive the annular ring of a condom in retaining or sealing relationship and gas inflation source is provided for producing a gas flow into the condom. By producing a pressure level to cause a detectable loss of air if the membrane has porosity in excess of a predetermined maximum degree the user can effectively test the condom for leaks. By associating the gas inflation sources with a composition selected to reside in the condom during use and effective against sperm or disease organisms, the user may achieve an improved degree of protection. The devices shown define an elongated, generally cylindrical forming member, which may be nestable annular elements, which extends from the circular surface that is engaged by the ring of the condom into the tubular membrane, adapted to support the condom to enable it to be unrolled into position for treatment and rerolled upon itself into compact form ready for use. Both a bellows and an aerosol can are shown for inflation and for injecting the active fluid composition. A storage compartment for pre-prepared condoms is advantageously pr…
