Abstract: A body fluids absorbent article has a liquid-permeable topsheet formed by a nonwoven fabric of thermoplastic synthetic fibers. The topsheet is formed with a plurality of openings each having a diameter of 0.5.about.3 mm. These openings queue up so as to form plural columns of openings extending in parallel one to another. One half or more of a total number of the openings are reinforced by strands of thermoplastic synthetic resin each having a diameter of 0.1.about.0.5 mm and extending circumferentially of the respective openings.

Abstract: An individually wrapped absorbent article such as a sanitary napkin which is simple, compact, sanitary, and easy to unwrap for use and to dispose of after use. The absorbent article avoids the need for a separate peel strip and pouch because it is provided with a wrapper that can be folded into a pouch. Substantially the entire backsheet of the absorbent article directly faces the wrapper and is secured to it to form an assembly. In the case of a winged or tabbed type absorbent article, this configuration obviates the need for a separate peel strip to cover the garment adhesive located on the wings or tabs. The assembly is wrapped by folding the lateral flaps thereof longitudinally over one another to enclose the article to prevent the garment adhesive from becoming contaminated. The package is then tri-folded laterally to form an e-shaped pouch. Wrapping and folding are performed by an in-line process that uses simple equipment and that does not require reversal in the direction of article conveyance.

Abstract: An improved incontinence fluid collection and disposal system consisting of a flexible fluid reservoir assembly mounted in an opening in a reusable brief is presented. The brief is either adjustable or one piece but in either case holds the fluid reservoir assembly snugly against the body to restrict fluid leakage. An adhesive layer, normally in the form of a gasket and affixed to a flange on an inlet end of the fluid reservoir assembly, can be used to hold the fluid reservoir in position against a layer in the brief. Additional gasket layer(s) in the form of other materials can also be utilized. The fluid reservoir assembly is, in its preferred embodiment, supplied with a gelatin agent to gelatinize the urine to make for easy removal and disposal. A bactericidal agent is supplied as part of the fluid reservoir assembly to prevent infections. An optional feature is a valve in the fluid reservoir assembly to which a collection tube can be attached for long term drainage.

Abstract: An urinary incontinence device for use by a male includes an undergarment worn closely to the body and including an opening or hole through which the penis passes and is kept upright and close to the body by a flap across the opener in the undergarment. The flap may include an occlusion device integrally incorporated therein and aligned with the opening to be positioned between the base of the shaft of the penis and the scrotum to occlude the urethral passage of the penis. The occlusion device is designed to apply sufficient pressure to occlude the urethral passage without cutting off circulation of blood within the penis through the dorsal vein. The flap design maintains and retains an optimum position of the penis and occlusion of the urethral passage to prevent urine discharge in a form fitting undergarment that allows significant freedom of movement by the wearer.
