Patent attributes
A wound dressing provides a tenacious occlusive seal against the skin of a wearer, even in the presence of excessive blood or heavy perspiration. The preferred embodiment combines an adhesive backing layer with a hydrogel island providing superior hydrophilic gel adhesion. The product performs under extreme temperatures (i.e., 32-140° F.), and may be used to hold other dressings in place. The preferred embodiments are entirely translucent, and include a large pull-tab for easy removal. Two dressings may be packaged in a pliable re-sealable protective pouch, thereby forming a portable “kit.” Different “vented” embodiments are disclosed. A preferred structure includes a cover layer peripherally bonded to backing and hydrogel layers having a central aperture therethrough. The cover layer has one or more vent holes, and pressure is released through the central aperture and out the vent hole(s).
