Abstract:
A breathable film for contact with skin wherein the film has texture variations is disclosed. The film is useful as a backing material for an adhesive bandage, and a bandage employing the film is easily applied to the skin of a user without inadvertently sticking to itself or surfaces other than the skin.

US Classification:
602 52
Abstract:
A surgical dressing consisting of a film which carries an adhesive layer wherein the film has a hydration rate of at least 0. 1 g/in. sup. 2 /min. ; becomes saturated when in contact with water in 3 minutes or less and absorbs at least its own weight of water. The film comprises a polyethylene oxide and a polymer or polymers selected from an ether based polyurethane and a polyether block amide. The dressing finds special use as a IV catheter site cover.
Adhesive Attachment System With A Non-Tacky Surface For Sanitary Napkins
This invention is directed to a pressure sensitive positioning adhesive for absorbent articles which can be used without release paper. The positioning adhesive has non-tacky irregularly shaped particles on its surface thereby rendering the adhesive non-tacky. Upon the application of pressure during use, i. e. , when attaching the napkin to the undergarment, the particles are rearranged, exposing adhesive to the undergarment, thereby facilitating attachment of the napkin to the undergarment.

Abstract:
An absorbent adhesive dressing is disclosed which is intended for use in treating wounds of the ulcer and burn type where there is significant wound exudate, which has a three layer sandwich-type construction having an occlusive film (e. g. polyethylene, polypropylene etc. ) as the outer layer, an absorbent layer of fibers (e. g. cellulose, synthetic fibers etc. ) as the middle layer, and a wet-stick adhesive as the inner wound facing adhesive layer, wherein said adhesive layer is a continuous, substantially non-pourous layer having a porosity of less than 0. 4 cc/sec/in. sup. 2 which is made from an acrylic polymer having both hydrophilic and hydrophobic characteristics (e. g. a wet-stick adhesive polymer formed from emulsion polymerization in water of N-vinyl caprolactam with n-butyl acrylate or with 2-ethylhexyl acrylate, or both, and which because of the hydrophilic nature of the polymer allows exudate to pass through the adhesive layer to the absorbent fibers of its middle layer without degrading the adhesive or its performance, and where the peripheral outer edges of the layers are optionally sealed.
