Patent

CA 2150401

An ostomy appliance of one-piece or two-piece construction having an adhesive faceplate with a stoma-receiving opening for peristomal adhesive attachment of the appliance to a wearer. The faceplate includes a flexible patch which may be formed of non-woven material and is covered on one side with a first layer of pressure-sensitive adhesive material -- particularly a skinfriendly, tacky, hydrocolloid-containing, moisture-absorbing skin barrier material -- surrounding the stoma-receiving opening, and a second layer of a soft, easily-deformable, and extrudable fluid-resistant sealant material also surrounding that opening. Inward displacement of the sealant material following adhesive attachment of the faceplate to a patient results in the formation in situ of a fluid-resistant gasket that prevents stomal fluids from contacting the peristomal skin surfaces and the first layer of skinfriendly adhesive and possibly dissolving that layer and/or disrupting its attachment to the skin.
