  • Patent number: 5702381
    Abstract: An absorbent product useful as a male incontinence device is disclosed. The product is convertible between a two-dimensional structure for storage and a three-dimensional structure for use. There are folds forming pleats located in the interior of the product to allow the interior to be expanded from a pleated configuration to an expanded configuration, and the periphery of the product is secured to prevent substantial expansion. Thus, the product is capable of being manipulated between a substantially two-dimensional planar structure for storage and a three-dimensional, cup-like structure for use. Methods of manufacturing these absorbent products are also disclosed.

  • Patent number: 4898594
    Abstract: An incontinence device which includes a garment having a sewn-in absorbent pad. A sheet of liquid impervious material is interposed between the garment and the surface of the absorbent pad remote from the wearer. The absorbent pad is coupled to the sheet of liquid-impervious material by stitching then the sheet is coupled to the garment by portions of the sheet turned back from the stitching of the pad to the sheet and stitched to the garment. In a further embodiment, a layer of permeable hydrophobic material is provided intermediate the pad and the wearer.

  • Patent number: 4753644
    Abstract: An incontinence device consisting of a rectangular pad of absorbent material incorporating along its upper surface at least one strip of a skeleton polyester foam material, the function of which is to enable urine to flow rapidly to the surface of those regions of the pad not immediately saturated by urine. In a preferred embodiment there are provided three strips of skeleton foam, two peripheral and one along the center line of the pad, to enhance further the capability of the device to absorb urine at high flow rates. A layer of hydrophyllic material may be provided between the foam strips and an outer permeable cover to enhance the wetting properties of the device at low flow rates and to eliminate discomfort caused to the patient by the rough surface of the foam material.
