Abstract

A one-piece urostomy appliance has a drainage bag secured to an apertured flange which is in turn secured to an apertured adhesive pad. The body side of the apertured flange has a flexible skirt encircling the stoma aperture and located adjacent the radially inner boundary of the adhesive pad. The skirt is constructed and located to impede leakage of urine towards the adhesive pad.

Claims

1. A one-piece urostomy appliance comprising a drainage bag secured to one side of an apertured flange which is in turn secured on its body side opposite the urostomy appliance to an apertured adhesive pad for securing the appliance to the body of the user, the body side of the apertured flange being provided with a flexible skirt encircling the stoma aperture and located adjacent the radially inner boundary of the adhesive pad, the flexible skirt extending from the rim of the flange aperture through the aperture in the adhesive pad towards the body of the wearer and extending beyond the skin-contacting surface of the adhesive pad on the body side of the pad, the rim of the flexible skirt adapted to make sealing contact with the skin of the body of the wearer spaced apart from and around the stoma to impede leakage of urine towards the inner boundary of the adhesive pad and the surface of the skin of the wearer, said apertured flange further comprising a substantially semi-circular arcuate rib or hood which extends into the bag and is positioned to keep a front or inner wall of the bag away from the stoma of the wearer.

2. An appliance according to claim 1 in which the flexible skirt is raised by about 0.5 to 1.00 mm above the skin-contacting surface of the apertured adhesive pad.
