Medical wraps

A method of manufacturing a wrap to treat living tissue, the method comprising:

• introducing a fibrous substrate into a gap defined by a mold roll and an opposed cooperating member, the mold roll defining an array of blind cavities shaped to form fastener elements or fastener element stems;
• extruding resin into the gap to form a discrete band of resin extending along the substrate and bonded to surface features of the substrate, the band being narrower than the substrate and leaving an adjacent area exposed and free of the resin;
• forming an array of fastener elements extending integrally from the band of resin, the fastener elements formed to provide a peel force characteristic of less than about 0.2 pounds per transverse inch of engaged width when releasably engaged with exposed surface fibers of the substrate;
• bonding a strip of resin to the substrate, such that the bonded strip is spaced apart from the band of resin;
• and
• cutting across the substrate, resin strip, and resin band to form individual wraps, each wrap of a length sufficient to enwrap an intended treatment site, and each wrap comprising a segment of the band of resin spaced apart from a segment of the strip of resin, and an exposed surface of the fibrous substrate.

A method of forming medical wraps for delivering medical treatments, the method comprising:

• extruding a resin into a gap defined by a mold roll and an opposed cooperating member, the mold roll defining an array of blind cavities shaped to form discrete fastener elements or fastener element stems extending from a flexible band of resin;
• introducing a sheet-form substrate into the gap such that the resin and the substrate are laminated forming a composite carrying both a field of fiber loops comprising exposed surface fibers of the substrate, the band of resin being narrower than the substrate and having an array of fastener elements or fastener element stems molded in the cavities;
• bonding a strip of resin to the substrate, such that the bonded strip is spaced apart from the band of resin across a width of the substrate;
• cutting the composite to form individual wraps, each wrap of a length sufficient to enwrap an intended treatment site and having both an area of fastener elements and an area of the releasably engageable fiber loops arranged to engage one another;
• welding to the strip of resin a medical function delivery pouch configured to contain materials selected to provide medical treatment to living tissue when the wrap is wrapped about the tissue;
• and
• inserting a medical function component into the pouch, the medical function component comprising a material selected from the group consisting of an absorbent material, or an endothermic material, or an exothermic material, or a predetermined medicinal treatment.
