| Abstract: |
The device includes a continuous flexible pouch which is entirely surrounded by a flange member which acts as a shield to cover the periphery of the vaginal entrance. The pouch, which is preferably in the form of a loose collapsed sheath, is arranged to be introduced into the user's vagina so as to form a liquid barrier between the penis and vagina. Straps and ribbed protrusions are provided for securely maintaining the flange member in its operational position. Preferably, an applicator rod is also provided.
