  • Patent number: 4875358
    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.
