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.
Claims10
An incontinence device comprising an elongate water-pervious cover, a pad consisting of absorbent material contained within said cover, and at least one strip of transmitting material extending longitudinally on the upper surface of said pad to cover the portions of said upper surface adjacent to both long edges of the pad, the transmitting material being hydrophobic having a three-dimensional opencelled structure defining pores of non-capillary size to offer substantially no resistance to liquid flow in any direction therethrough so that said strip provides a passage along which urine, not immediately absorbed by said pad, can flow readily to the surface of an unsaturated part of the pad.
