Abstract
A female urinary incontinence device including a periurethral cup, an external pad of soft, flexible, resilient material, and a compressible tubular elastic bellows extending between a lower opening of the cup and the inlet to a fluid discharge passage extending through the pad. The discharge passage extends forwardly (anteriorly) in a generally horizontal direction along the sagittal midplane of the pad, and the undersurface of the pad is provided with laterally-disposed and generally-horizontal surface portions, and preferably also a coplanar medial surface portion, for distributing forces and preventing inversion of the pad when a wearer is seated. A flexible discharge tube has one end detachably connected to the pad's discharge passage by means of a tubular coupling having an insert portion received in the outlet of that passage. The coupling includes a laterally-directed vent and valve, and an upwardly-extending T-shaped (in section) projection of the coupling is frictionally received in a T-shaped slot in the pad for preventing rotation of the coupling with respect to the pad and for holding the coupling in alignment, and in flow communication, with the pad's discharge passag…
