  • Publication number: 20050107752
    Abstract: The novel idea of the present invention is to fabricate spiral configuration into the annular recessed cylindrical wall around the spray nozzle on the face plate of certain kinds of currently marketed hand-held and wall-mounted showerheads to allow a coupling feature in place for screw-on connection by our specially designed disposable vaginal douche nozzle. The showerhead water flow path for the douche nozzle shares the same water flow path with the spray nozzle. User can access the douche mode by selecting the existing spray mode of the spray nozzle wherein it has a coupling structure attachable to our douche nozzle. The spray pattern of the spray nozzle stays unaffected when our douche nozzle is not attached. In accordance with the present invention, adequate and efficient vaginal deodorization may be accomplished by douching with only normal household water that ensures minimal alteration of vaginal pH while rinsing out the vaginal canal.
