  • Patent number: 5318553
    Abstract: A unitary sanitary disposable absorbent incontinence pad has an elongated absorbent member between a pervious cover topsheet and an impervious backsheet. The absorbent member includes an absorbent batt which contains a combination of cellulose fibers and thermally-bondable fibers. A melt-blown web is superimposed on the batt. A portion of each lateral side of the batt is slit and turned inwardly toward the center of the batt to form a pair of fluid-barriers or dams, creating a fluid channel therebetween. The melt-blown web lies between the dams on top of the batt. Preferably the melt-blown web includes inturned side edges which may create a second channel therebetween. The assembly of batt and web are particularly effective for moving fluid longitudinally in said pad and preventing leakage along the sides of the pad.

  • Patent number: 5203806
    Abstract: An absorbent pad for use with an ostomy appliance or similar apparatus connected to a stoma extending through the skin of a patient, is formed of a flexible laminate with a liquid-permeable inner layer facing toward the patient's skin, an intermediate layer of absorbent material, and a liquid-impermeable outer layer. The layers are sealed together, and the laminate has a central opening for fitting around the connection between the ostomy appliance flange and body portion. An adhesive layer is provided on the peripheral border of the pad for sealing to the patient's skin. The adhesive layer is applied so that it encircles the absorbent surface area of the pad. The adhesive layer cooperates with the impermeable outer layer of the laminate to surround the fluid-absorbing intermediate layers of the pad and prevent fluid and odor absorbed therein from being released. The absorbent pad is further characterized in that it can be applied and disposed of separate and apart from the ostomy appliance.
