Abstract
An improved wound dressing having an adhesive layer (26, 426) containing one or more hydrocolloids dispersed in a viscous elastomer, a flexible water-impervious backing layer (22, 322, 422) on one side of the adhesive layer, and a removable release layer (28, 328, 428) on the adhesive layer's opposite side. The dressing includes a body portion (36) with a stair-like outer contour merging with a peripheral flange (38, 238, 338, 438) of reduced thickness. The flange (38, 238, 338, 438) is required to have a width of at least 5 mm. and the thickness of the adhesive layer of that flange is no greater than 0.5 mm., for purposes of overcoming prior problems of adhesive flow, fluid channeling, leakage, and unintentional detachment.
