BRIEF SUMMARY
BACKGROUND OF THE INVENTION
This invention relates to an artificial vagina and more particularly to a male sexual gratification device.
Due to the current worlwide risks of life threatening infections such as AIDS (Acquired Immunity Deficiency Syndrome) care must be exercised in sexual relationships by using protection such as condoms to prevent the spread of the infection. The alternatives to this are total abstinence from sexual intercourse, or self-gratification for prudent sexually unfulfilled mature males unable to attain otherwise satisfying monogamous relationships with consenting female partners.
Although devices of this type are available, they have the disadvantage that they are not 100% reliable from the point of view of hygiene.
SUMMARY OF THE INVENTION
An aim of the present invention is to overcome the above disadvantage and to provide a device which fulfills its purpose and is hygienically maintained.
According to the present invention there is provided an artificial vagina comprising a tapered sheath of flexible waterproof material, the larger end of which has an opening re-sealable by a removable closure member, the closure member having releasable means to connect with the other end of the sheath to pull this into the sheath so that a fluid chamber is formed between the inwardly folded end and the wall of the other end of the sheath.
Preferably, the closure member is a screw-threaded stopper, and the releasable means is a loop and swivel hook connection.
Conveniently, the outer wall of the sheath has an annular membrane, the inner circumference of which has a ring shaped reinforced elastic rib.
In a preferred construction the sheath is formed with a bulbous portion adjacent the annular membrane where it joins the sheath wall.
BRIEF DESCRIPTION OF THE INVENTION
An embodiment of the artificial vagina will now be described by way of example only, with reference to the accompanying drawings, in which:
FIG. 1 is a diagrammatic longitudinal section of the artificial vagina according to the invention;
FIG. 2 is a longitudinal section of the artificial vagina in its assembled position for use; and
FIG. 3 is an end elevation of the artificial vagina shown in FIG. 2.
DESCRIPTION OF THE PREFERRED EMBODIMENT
The artificial vagina illustrated comprises a sheath 1 made from a flexible waterproof material such as rubber or an elastomeric plastics material. The sheath tapers from one end to the other, the wider end having a re-sealable opening 2 closed by a screw-threaded stopper 3 which screws into and forms a seal with a screw-thread moulded in the sheath opening 2. Projecting from the inner end of the stopper is an eye loop 4 which is connected to a hook 5 which swivels on a wire connection 6 secured to a tab 7 formed integral with the sheath 1.
The tapered end of the sheath 1 is moulded with a soft flexible portion formed with an undulating wall 8. Intermediate the ends of the sheath the wall has a bulbous portion 9 from which extends an annular membrane 10 the outer peripheral edge of which has a reinforced elastic rib 11 extending around the outside of the sheath 1.
To assemble the device the tapered end of the sheath is pushed into the wider end and the hook 5 is connected to the loop 4 carried by the stopper 3 to form an annular fluid chamber 12. The wire connection 6 allows the hook 5 to swivel while hooked to the eye loop 4 when the stopper 3 is tightened to seal the sheath opening 2. The chamber 12 is filled with warm water 13 or another suitable fluid through the opening 2 which is sealed by screwing in the stopper 3.
By inverting the tapered end of the sleeve a flexible chamber 14 is formed for receiving a male penis. To simulate the shape of a female vagina the bulbous portion 9 projects into the extrance of the chamber 12 to form a clitoris (see FIG. 3) and has an aperture 15 to allow the warm water from the chamber 12 to fill the bulbous portion 9.
The assembled sheath, when filled with warm water, becomes a warm soft envelope closely resembling a female vagina, clitoris, hymen a
