  • Publication number: 20220395401
    Abstract: The disclosed adhesive medical article has a backing layer having a first major surface and a second major surface opposite to the first major surface. The backing layer has a central portion and an outer circumferential portion. The article further has a pressure sensitive adhesive pattern coating applied onto at least part of the first major surface of the backing layer in such a way as to form a plurality of adhesive coated and adhesive uncoated areas of the backing layer. The adhesive uncoated areas comprise a central collection portion and at least one longitudinal extension radiating from the central collection portion towards the outer circumferential portion of the backing layer.
