MEDICAL DRESSING

摘要

A medical dressing including a support material layer, a backing layer, and an adhesive. The adhesive forms a window. The backing layer extends over the window and is spatially affixed to the adhesive along an attachment region that surrounds, but is spatially offset from, an edge of the window. When used to cover an object on a patient's skin, the object bears against the backing layer and generates a lifting force onto the adhesive in a direction opposite the patient's skin. The off-set attachment region interior border dissipates the lifting force, transferring it to the adhesive as a shear-type force. The adhesive readily resists the shear-type force, providing the medical dressing with an elevated wear life.
