Vaginal contraceptive shield

摘要

A flexible contraceptive vaginal shield having a supporting structure with an outer ring and an internal member which may comprise one or more concentric rings with or without a plurality of ribs connecting the rings said structure bonded to a flexible non-elastomeric film. A spermicide is normally applied to both sides of the film. The bonding of the supporting structure to the film is preferably by heat sealing. Spermicide applied to the ring side of the film is retained within reservoirs formed by the rings, the ribs and the film. In addition there may be reservoirs formed within the supporting structure that release spermicide through the flexing action caused by sexual intercourse.
